Vancomicina combino

Overdose

Toxicity due to overdose has been reported. 500 mg IV to a child, 2 year of age, resulted in lethal intoxication. Administration of a total of 56 g during 10 days to an adult resulted in renal insufficiency. In certain high-risk conditions (e. g. in case of severe renal impairment) high serum levels and oto- and nephrotoxic effects can occur.

Measures in case of overdose

- A specific antidote is not known.

- Symptomatic treatment while maintaining renal function is required.

- Vancomicina Combino is poorly removed from the blood by haemodialysis or peritoneal dialysis. Haemofiltration or haemoperfusion with polysulfone resins have been used to reduce serum concentrations of Vancomicina Combino.

Contraindications

Vancomicina Combino should not be administered intramuscularly due to the risk of necrosis at the site of administration.

Incompatibilities

Vancomicina Combino has a low pH that may cause chemical or physical instability when it is mixed with other substances. Therefore, each parenteral solution should be checked visually for precipitations and discolouration prior to use.

Combination therapy

In case of combination therapy of Vancomicina Combino with other antibiotics/chemotherapeutics, the preparations should be administered separately.

Mixtures of solutions of Vancomicina Combino and beta-lactam antibiotics have been shown to be physically incompatible. The likelihood of precipitation increases with higher concentrations of Vancomicina Combino. It is recommended to adequately flush the intravenous lines between administration of these antibiotics. It is also recommended to dilute solutions of Vancomicina Combino to 5 mg/ml or less.

Undesirable effects

Summary of the Safety profile

The most common adverse reactions are phlebitis, pseudo-allergic reactions and flushing of the upper body (“red-neck syndrome”) in connection with too rapid intravenous use of Vancomicina Combino.

Tabulated List of Adverse reactions

Within each frequency grouping, undesirable effects are presented in order of decreasing seriousness.

The adverse reactions listed below are defined using the following MedDRA convention and system organ class database:

Very common (> 1/10); common (> 1/100 to < 1/10); uncommon (> 1/1,000 to < 1/100); rare (> 1/10,000 to < 1/1,000); very rare (< 1/10,000), not known (cannot be estimated from the available data).

Description of selected adverse drug reactions

Reversible neutropenia usually starting one week or more after onset of intravenous therapy or after total dose of more than 25 g.

During or shortly after rapid infusion anaphylactic/anaphylactoid reactions including wheezing may occur. The reactions abate when administration is stopped, generally between 20 minutes and 2 hours. Vancomicina Combino should be infused slowly. Necrosis may occur after intramuscular injection.

Tinnitus, possibly preceding onset of deafness, should be regarded as an indication to discontinue treatment.

Ototoxicity has primarily been reported in patients given high doses, or in those on concomitant treatment with other ototoxic medicinal product like aminoglycoside, or in those who had a pre-existing reduction in kidney function or hearing.

If a bullous disorder is suspected, the drug should be discontinued and specialised dermatological assessment should be carried out.

Paediatric population

The safety profile is generally consistent among children and adult patients. Nephrotoxicity has been described in children, usually in association with other nephrotoxic agents such as aminoglycosides.

Reporting of suspected adverse reactions

Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the national reporting system listed in: Yellow Card Scheme

Preclinical safety data

Non-clinical data reveal no special hazard for humans based on conventional studies of safety pharmacology and repeated dose toxicity.

Limited data on mutagenic effects show negative results, long-term studies in animals regarding a carcinogenic potential are not available. In teratogenicity studies, where rats and rabbits received doses approximately corresponding to the human dose based on body surface (mg/m2), no direct or indirect teratogenic effects were observed.

Animal studies of the use during the perinatal/postnatal period and regarding effects on fertility are not available.

Therapeutic indications

Intravenous administration

Vancomicina Combino is indicated in all age groups for the treatment of the following infections :

- complicated skin and soft tissue infections (cSSTI)

- bone and joint infections

- community acquired pneumonia (CAP)

- hospital acquired pneumonia (HAP), including ventilator-associated pneumonia (VAP)

- infective endocarditis

Vancomicina Combino is also indicated in all age groups for the perioperative antibacterial prophylaxis in patients that are at high risk of developing bacterial endocarditis when undergoing major surgical procedures.

Consideration should be given to official guidance on the appropriate use of antibacterial agents.

Pharmacotherapeutic group

Pharmacodynamic properties

Pharmacotherapeutic group: Glycopeptide antibacterials, ATC Code: J01XA01.

Mechanism of action

Vancomicina Combino is a tricyclic glycopeptide antibiotic that inhibits the synthesis of the cell wall in sensitive bacteria by binding with high affinity to the D-alanyl-D-alanine terminus of cell wall precursor units. The drug is slowly bactericidal for dividing microorganisms. In addition, it impairs the permeability of the bacterial cell membrane and RNA synthesis.

Pharmacokinetic/ Pharmacodynamic relationship

Vancomicina Combino displays concentration-independent activity with the area under the concentration curve (AUC) divided by the minimum inhibitory concentration (MIC) of the target organism as the primary predictive parameter for efficacy. On basis of in vitro, animal and limited human data, an AUC/MIC ratio of 400 has been established as a PK/PD target to achieve clinical effectiveness with Vancomicina Combino. To achieve this target when MICs are > 1.0 mg/l, dosing in the upper range and high trough serum concentrations (15-20 mg/l) are required.

Mechanism of resistance

Acquired resistance to glycopeptides is most common in enterococci and is based on acquisition of various van gene complexes which modifies the D-alanyl-D-alanine target to D-alanyl-D-lactate or D-alanyl-D-serine which bind Vancomicina Combino poorly. In some countries, increasing cases of resistance are observed particularly in enterococci; multi-resistant strains of Enterococcus faecium are especially alarming.

Van genes have rarely been found in Staphylococcus aureus, where changes in cell wall structure result in “intermediate” susceptibility, which is most commonly heterogeneous. Also, methicillin-resistant staphylococcus strains (MRSA) with reduced susceptibility for Vancomicina Combino were reported. The reduced susceptibility or resistance to Vancomicina Combino in Staphylococcus is not well understood. Several genetic elements and multiple mutations are required.

There is no cross-resistance between Vancomicina Combino and other classes of antibiotics. Cross-resistance with other glycopeptide antibiotics, such as teicoplanin, does occur. Secondary development of resistance during therapy is rare.

Synergism

The combination of Vancomicina Combino with an aminoglycoside antibiotic has a synergistic effect against many strains of Staphylococcus aureus, non-enterococcal group D-streptococci, enterococci and streptococci of the Viridans group. The combination of Vancomicina Combino with a cephalosporin has a synergistic effect against some oxacillin-resistant Staphylococcus epidermidis strains, and the combination of Vancomicina Combino with rifampicin has a synergistic effect against Staphylococcus epidermidis and a partial synergistic effect against some Staphylococcus aureus strains. As Vancomicina Combino in combination with a cephalosporin may also have an antagonistic effect against some Staphylococcus epidermidis strains and in combination with rifampicin against some Staphylococcus aureus strains, preceding synergism testing is useful.

Specimens for bacterial cultures should be obtained in order to isolate and identify the causative organisms and to determine their susceptibility to Vancomicina Combino.

Susceptibility testing breakpoints

Vancomicina Combino is active against gram-positive bacteria, such as staphylococci, streptococci, enterococci, pneumococci, and clostridia. Gram-negative bacteria are resistant.

The prevalence of acquired resistance may vary geographically and with time for selected species and local information on resistance is desirable, particularly when treating severe infections. As necessary, expert advice should be sought when the local prevalence of resistance is such that the utility of the agent in at least some types of infections is questionable. This information only provides approximate guidance on the chance whether micro-organisms are susceptible to Vancomicina Combino.

Minimum inhibitory concentration (MIC) breakpoints established by the European Committee on Antimicrobial Susceptibility Testing (EUCAST) are as follows:

1S. aureus with Vancomicina Combino MIC values of 2 mg/L are on the border of the wild type distribution and there may be an impaired clinical response.

Pharmacokinetic properties

Absorption

Vancomicina Combino is administered intravenously for the treatment of systemic infections.

In the case of patients with normal renal function, intravenous infusion of multiple doses of 1g Vancomicina Combino (15 mg/kg) for 60 minutes produces approximate average plasma concentrations of 50-60 mg/L, 20-25 mg/L and 5-10 mg/L, immediately, 2 hours and 11 hours after completing the infusion, respectively. The plasma levels obtained after multiple doses are similar to those achieved after a single dose.

Distribution

The volume of distribution is about 60 L/1.73 m2 body surface. At serum concentrations of Vancomicina Combino of 10 mg/l to 100 mg/l, the binding of the drug to plasma proteins is approximately 30-55%, measured by ultra-filtration.

Vancomicina Combino diffuses readily across the placenta and is distributed into cord blood. In non-inflamed meninges, Vancomicina Combino passes the blood-brain barrier only to a low extent.

Biotransformation

There is very little metabolism of the drug. After parenteral administration it is excreted almost completely as microbiologically active substance (approx. 75-90% within 24 hours) through glomerular filtration via the kidneys.

Elimination

The elimination half-life of Vancomicina Combino is 4 to 6 hours in patients with normal renal function and 2.2-3 hours in children. Plasma clearance is about 0.058 L/kg/h and kidney clearance about 0.048 L/kg/h. In the first 24 hours, approximately 80 % of an administered dose of Vancomicina Combino is excreted in the urine through glomerular filtration. Renal dysfunction delays the excretion of Vancomicina Combino. In anephric patients, the mean half-life is 7.5 days. Due to ototoxicity of Vancomicina Combino therapy-adjuvant monitoring of the plasma concentrations is indicated in such cases.

Biliary excretion is insignificant (less than 5% of a dose).

Although the Vancomicina Combino is not eliminated efficiently by haemodialysis or peritoneal dialysis, there have been reports of an increase in Vancomicina Combino clearance with haemoperfusion and haemofiltration.

Linerarity/non-linearity

Vancomicina Combino concentration generally increases proportionally with increasing dose. Plasma concentrations during multiple dose administration are similar to those after the administration of a single dose.

Characteristics in specific groups

Renal impairment

Vancomicina Combino is primarily cleared by glomerular filtration. Posology and method of administration.

Hepatic impairment

Vancomicina Combino pharmacokinetics is not altered in patients with hepatic impairment.

Pregnant Women

Significantly increased doses may be required to achieve therapeutic serum concentrations in pregnant women.

Overweight patients

Vancomicina Combino distribution may be altered in overweight patients due to increases in volume of distribution, in renal clearance and possible changes in plasma protein binding. In these subpopulations Vancomicina Combino serum concentration was found higher than expected in male healthy adults.

Paediatric population

Vancomicina Combino PK has shown wide inter-individual variability in preterm and term neonates. In neonates, after intravenous administration, Vancomicina Combino volume of distribution varies between 0.38 and 0.97 L/kg, similar to adult values, while clearance varies between 0.63 and 1.4 ml/kg/min. Half-life varies between 3.5 and 10 h and is longer than in adults, reflecting the usual lower values for clearance in the neonate.

In infants and older children, the volume of distribution ranges between 0.26-1.05 L/kg while clearance varies between 0.33-1.87 ml/kg/min.

Qualitative and quantitative composition

Special warnings and precautions for use

Hypersensitivity reactions

Serious and occasionally fatal hypersensitivity reactions are possible. In case of hypersensitivity reactions, treatment with Vancomicina Combino must be discontinued immediately and the adequate emergency measures must be initiated.

In patients receiving Vancomicina Combino over a longer-term period or concurrently with other medications which may cause neutropenia or agranulocytosis, the leukocyte count should be monitored at regular intervals. All patients receiving Vancomicina Combino should have periodic haematologic studies, urine analysis, liver and renal function tests.

Vancomicina Combino should be used with caution in patients with allergic reactions to teicoplanin, since cross hypersensitivity, including fatal anaphylactic shock, may occur.

Spectrum of antibacterial activity

Vancomicina Combino has a spectrum of antibacterial activity limited to Gram-positive organisms. It is not suitable for use as a single agent for the treatment of some types of infections unless the pathogen is already documented and known to be susceptible or there is a high suspicion that the most likely pathogen(s) would be suitable for treatment with Vancomicina Combino.

The rational use of Vancomicina Combino should take into account the bacterial spectrum of activity, the safety profile and the suitability of standard antibacterial therapy to treat the individual patient.

Ototoxicity

Ototoxicity, which may be transitory or permanent has been reported in patients with prior deafness, who have received excessive intravenous doses, or who receive concomitant treatment with another ototoxic active substance such as an aminoglycoside. Vancomicina Combino should also be avoided in patients with previous hearing loss. Deafness may be preceded by tinnitus. Experience with other antibiotics suggests that deafness may be progressive despite cessation of treatment. To reduce the risk of ototoxicity, blood levels should be determined periodically and periodic testing of auditory function is recommended.

The elderly are particularly susceptible to auditory damage. Monitoring of vestibular and auditory function in the elderly should be carried out during and after treatment. Concurrent or sequential use of other ototoxic substances should be avoided.

Infusion-related reactions

Rapid bolus administration (i.e. over several minutes) may be associated with exaggerated hypotension (including shock and, rarely, cardiac arrest), histamine like responses and maculopapular or erythematous rash (“red man's syndrome” or “red neck syndrome”). Vancomicina Combino should be infused slowly in a dilute solution (2.5 to 5.0 mg/ml) at a rate no greater than 10 mg/min and over a period not less than 60 minutes to avoid rapid infusion-related reactions. Stopping the infusion usually results in a prompt cessation of these reactions.

The frequency of infusion-related reactions (hypotension, flushing, erythema, urticaria and pruritus) increases with the concomitant administration of anaesthetic agents. This may be reduced by administering Vancomicina Combino by infusion over at least 60 minutes, before anaesthetic induction.

Severe bullous reactions

Stevens-Johnson syndrome (SJS) has been reported with the use of Vancomicina Combino. If symptoms or signs of SJS (e.g. progressive skin rash often with blisters or mucosal lesions) are present, Vancomicina Combino treatment should be discontinued immediately and specialised dermatological assessment be sought.

Administration site related reactions

Pain and thrombophlebitis may occur in many patients receiving intravenous Vancomicina Combino and are occasionally severe. The frequency and severity of thrombophlebitis can be minimized by administering the medicinal product slowly as a dilute solution and by changing the sites of infusion regularly.

The efficacy and safety of Vancomicina Combino has not been established for the intrathecal, intralumbar and intraventricular routes of administration.

Nephrotoxicity

Vancomicina Combino should be used with care in patients with renal insufficiency, including anuria, as the possibility of developing toxic effects is much higher in the presence of prolonged high blood concentrations. The risk of toxicity is increased by high blood concentrations or prolonged therapy.

Regular monitoring of the blood levels of Vancomicina Combino is indicated in high dose therapy and longer-term use, particularly in patients with renal dysfunction or impaired faculty of hearing as well as in concurrent administration of nephrotoxic or ototoxic substances, respectively.

Paediatric population

The current intravenous dosing recommendations for the paediatric population, in particular for children below 12 years of age, may lead to sub-therapeutic Vancomicina Combino levels in a substantial number of children. However, the safety of increased Vancomicina Combino dosing has not been properly assessed and higher doses than 60 mg/kg/day cannot be generally recommended.

Vancomicina Combino should be used with particular care in premature neonates and young infants, because of their renal immaturity and the possible increase in the serum concentration of Vancomicina Combino. The blood concentrations of Vancomicina Combino should therefore be monitored carefully in these children. Concomitant administration of Vancomicina Combino and anaesthetic agents has been associated with erythema and histamine-like flushing in children. Similarly, concomitant use with nephrotoxic agents such as aminoglycoside antibiotics, NSAIDs (e.g., ibuprofen for closure of patent ductus arteriosus) or amphotericin B is associated with an increased risk of nephrotoxicity and therefore more frequent monitoring of Vancomicina Combino serum levels and renal function is indicated.

Use in the elderly

The natural decrement of glomerular filtration with increasing age may lead to elevated Vancomicina Combino serum concentrations if dosage is not adjusted.

Drug interactions with anaesthetic agents

Anaesthetic induced myocardial depression may be enhanced by Vancomicina Combino. During anaesthesia, doses must be well diluted and administered slowly with close cardiac monitoring. Position changes should be delayed until the infusion is completed to allow for postural adjustment.

Pseudomembranous enterocolitis

In case of severe persistent diarrhoea the possibility of pseudomembranous enterocolitis that might be life-threatening has to be taken into account. Anti-diarrhoeic medicinal products must not be given.

Superinfection

Prolonged use of Vancomicina Combino may result in the overgrowth of non-susceptible organisms. Careful observation of the patient is essential. If superinfection occurs during therapy, appropriate measures should be taken.

Effects on ability to drive and use machines

Vancomicina Combino has no or negligible influence on the ability to drive and use machines.

Dosage (Posology) and method of administration

Posology

Where appropriate, Vancomicina Combino should be administered in combination with other antibacterial agents.

Intravenous administration

The initial dose should be based on total body weight. Subsequent dose adjustments should be based on serum concentrations to achieve targeted therapeutic concentrations. Renal function must be taken into consideration for subsequent doses and interval of administration

Patients aged 12 years and older

The recommended dose is 15 to 20 mg/kg of body weight every 8 to 12 h (not to exceed 2 g per dose).

In seriously ill patients, a loading dose of 25-30 mg/kg of body weight can be used to facilitate rapid attainment of target trough serum Vancomicina Combino concentration.

Infants and children aged from one month to less than 12 years of age:

The recommended dose is 10 to 15 mg/kg body weight every 6 hours.

Term neonates (from birth to 27 days of post-natal age) and preterm neonates (from birth to the expected date of delivery plus 27 days)

For establishing the dosing regimen for neonates, the advice of a physician experienced in the management of neonates should be sought. One possible way of dosing Vancomicina Combino in neonates is illustrated in the following table:

PMA: post-menstrual age [(time elapsed between the first day of the last menstrual period and birth (gestational age) plus the time elapsed after birth (post-natal age)].

Peri-operative prophylaxis of bacterial endocarditis in all age groups

The recommended dose is an initial dose of 15 mg/kg prior to induction of anaesthesia. Depending on the duration of surgery, a second Vancomicina Combino dose may be required.

Duration of treatment

Suggested treatment duration is shown in table below. In any case, the duration of treatment should be tailored to the type and severity of infection and the individual clinical response.

*Continue until further debridement is not necessary, patient has clinically improved, and patient is afebrile for 48 to 72 hours

**Longer courses of oral suppression treatment with suitable antibiotics should be considered for prosthetic joint infections

***Duration and need for combination therapy is based on valve-type and organism

Special populations

Elderly

Lower maintenance doses may be required due to the age-related reduction in renal function.

Renal impairment

In adult and paediatric patients with renal impairment, consideration should be given to an initial starting dose followed by serum Vancomicina Combino trough levels rather than to a scheduled dosing regimen, particularly in patients with severe renal impairment or those who undergo renal replacement therapy (RRT) due to the many varying factors that may affect Vancomicina Combino levels in them.

In patients with mild or moderate renal failure, the starting dose must not be reduced. In patients with severe renal failure, it is preferable to prolong the interval of administration rather than administer lower daily doses.

Appropriate consideration should be given to the concomitant administration of medicinal products that may reduce Vancomicina Combino clearance and/or potentiate its undesirable effects.

Vancomicina Combino is poorly dialyzable by intermittent hemodialysis. However, use of high-flux membranes and continuous renal replacement therapy (CRRT) increases Vancomicina Combino clearance and generally requires replacement dosing (usually after the haemodialysis session in case of intermittent haemodialysis).

Adults

Dose adjustments in adult patients could be based on glomerular filtration rate estimated (eGFR) by the following formula:

Men: [Weight (kg) x 140 - age (years)]/ 72 x serum creatinine (mg/dl)

Women: 0.85 x value calculated by the above formula.

The usual starting dose for adult patients is 15 to 20 mg/kg that could be administered every 24 hours in patients with creatinine clearance between 20 to 49 ml/min. In patients with severe renal impairment (creatinine clearance below 20 ml/min) or those on renal replacement therapy, the appropriate timing and amount of subsequent doses largely depend on the modality of RRT and should be based on serum Vancomicina Combino trough levels and on residual renal function. Depending on the clinical situation, consideration could be given to withhold the next dose while awaiting the results of Vancomicina Combino levels.

In the critically ill patient with renal insufficiency, the initial loading dose (25 to 30 mg/kg) should not be reduced.

Paediatric population

Dose adjustments in paediatric patients aged 1 year and older could be based on glomerular filtration rate estimated (eGFR) by the revised Schwartz formula:

eGFR (mL/min/1.73m2) = (height cm x 0.413)/ serum creatinine (mg/dl)

eGFR (mL/min/1.73m2) = (height cm x 36.2/serum creatinine (μmol/L)

For neonates and infants below 1 year of age, expert advice should be sought as the revised Schwartz formula is not applicable to them.

Orientative dosing recommendations for the paediatric population are shown in table below that follow the same principles as in adult patients.

*The appropriate timing and amount of subsequent doses largely depends on the modality of RRT and should be based on serum Vancomicina Combino levels obtained prior to dosing and on residual renal function. Depending on the clinical situation, consideration could be given to withhold the next dose while awaiting the results of Vancomicina Combino levels.

Hepatic impairment

No dose adjustment is needed in patients with hepatic insufficiency.

Pregnancy

Significantly increased doses may be required to achieve therapeutic serum concentrations in pregnant women.

Obese patients

In obese patients, the initial dose should be individually adapted according to total body weight as in non-obese patients.

Monitoring of Vancomicina Combino serum concentrations

The frequency of therapeutic drug monitoring (TDM) needs to be individualized based on the clinical situation and response to treatment, ranging from daily sampling that may be required in some hemodynamically unstable patients to at least once weekly in stable patients showing a treatment response. In patients with normal renal function, the serum concentration of Vancomicina Combino should be monitored on the second day of treatment immediately prior to the next dose.

In patients on intermittent haemodialysis, Vancomicina Combino levels should be usually obtained before the start of the haemodialysis session.

Therapeutic trough (minimum) Vancomicina Combino blood levels should normally be 10-20 mg/l, depending on the site of infection and susceptibility of the pathogen. Trough values of 15-20 mg/l are usually recommended by clinical laboratories to better cover susceptible-classified pathogens with MIC >1 mg/L.

Model-based methods may be useful in the prediction of individual dose requirements to reach an adequate AUC. The model-based approach can be used both in calculating the personalized starting dose and for dose adjustments based on TDM results.

Method of administration:

Intravenous administration

Intravenous Vancomicina Combino is usually administered as an intermittent infusion and the dosing recommendations presented in this section for the intravenous route correspond to this type of administration.

Vancomicina Combino shall only be administered as slow intravenous infusion of at least one hour duration or at a maximum rate of 10 mg/min (whichever is longer) which is sufficiently diluted (at least 100 ml per 500 mg or at least 200 ml per 1000 mg).

Patients whose fluid intake must be limited can also receive a solution of 500 mg/50 ml or 1000 mg/100 ml, although the risk of infusion-related undesirable effects can be increased with these higher concentrations.

Continuous Vancomicina Combino infusion may be considered, e.g., in patients with unstable Vancomicina Combino clearance.

Special precautions for disposal and other handling

The product must be reconstituted and the resulting concentrate must then be diluted immediately prior to use.

Preparation of the reconstituted concentrate

Dissolve Vancomicina Combino 1000 mg Powder for concentrate for solution for infusion in 20 ml of sterile Water for injection.

One ml of reconstituted concentrate contains 50 mg of Vancomicina Combino.

Appearance of reconstituted concentrate

After reconstitution, the solution is clear and colourless to slightly yellowish brown without visible particles.

Preparation of final diluted Solution for infusion

Reconstituted solutions containing 50 mg/ml of Vancomicina Combino should be further diluted.

Suitable diluents are:

Sodium Chloride 9 mg/ml (0.9%) Injection

Glucose 50 mg/ml (5%) Injection

Intermittent infusion:

Reconstituted solution containing 1000 mg Vancomicina Combino (50 mg/ml) must be diluted further with at least 200 ml diluent (to 5 mg/ml).

The concentration of Vancomicina Combino in Solution for infusion should not exceed 5 mg/ml.

The desired dose should be administered slowly by intravenous use at a rate of no more than 10 mg/minute, for at least 60 minutes or even longer.

Continuous infusion:

This should be used only if treatment with an intermittent infusion is not possible. Dilute 1000 mg to 2000 mg of dissolved Vancomicina Combino in a sufficient amount of the above suitable diluent and administer it in the form of a drip infusion, so that the patient will receive the prescribed daily dose in 24 hours.

Appearance of diluted solution

After dilution the solution is clear, free from extraneous particles.

Before administration, the reconstituted and diluted solutions should be inspected visually for particulate matter and discoloration. Only clear and colourless solution free from particles should be used.

Disposal

Vials are for single use only. Unused medicinal products must be discarded.

Any unused medicinal product or waste material should be disposed of in accordance with local requirements.
