What is the most important information I should know about Praziquantel?
Praziquantel (praziquantel) is contraindicated in patients who previously have shown hypersensitivity to the drug or any of the excipients. Since parasite destruction within the eye may cause irreversible lesions, ocular cysticercosis must not be treated with this compound.
Concomitant administration with strong Cytochrome P450 (P450) inducers, such as rifampin, is contraindicated since therapeutically effective blood levels of praziquantel may not be achieved. In patients receiving rifampin who need immediate treatment for schistosomiasis, alternative agents for schistosomiasis should be considered. However, if treatment with praziquantel is necessary, rifampin should be discontinued 4 weeks before administration of praziquantel. Treatment with rifampin can then be restarted one day after completion of praziquantel treatment.
The following adverse reactions were observed in clinical field trials with Lufenuron for Cats: pain on injection, injection site lumps/granulomas, vomiting, listlessness/lethargy and anorexia.
Histologic examination of one cat’s injection site lump showed evidence of inflammation surrounding an area of necrosis with marked proliferation of fibrous connective tissue. In another cat, granulamatous inflammation was noted which included non-pleomorphic fibrocytes and fibroplasia.
The following adverse reactions have been reported following the use of Milbemycin Oxime: Depression/lethargy, vomiting, ataxia, anorexia, diarrhea, convulsions, weakness and hypersalivation.

In addition to its needed effects, some unwanted effects may be caused by praziquantel (the active ingredient contained in Praziquantel). In the event that any of these side effects do occur, they may require medical attention.

Some of the side effects that can occur with praziquantel may not need medical attention. As your body adjusts to the medicine during treatment these side effects may go away. Your health care professional may also be able to tell you about ways to reduce or prevent some of these side effects. If any of the following side effects continue, are bothersome or if you have any questions about them, check with your health care professional:

inflammatory disorders
An indication is a term used for the list of condition or symptom or illness for which the medicine is prescribed or used by the patient. For example, acetaminophen or paracetamol is used for fever by the patient, or the doctor prescribes it for a headache or body pains. Now fever, headache and body pains are the indications of paracetamol. A patient should be aware of the indications of medications used for common conditions because they can be taken over the counter in the pharmacy meaning without prescription by the Physician.Praziquantel (praziquantel) is indicated for the treatment of infections due to: all species of schistosoma (for example, Schistosoma mekongi, Schistosoma japonicum, Schistosoma mansoni and Schistosoma hematobium), and infections due to the liver flukes, Clonorchis sinensis/Opisthorchis viverrini (approval of this indication was based on studies in which the two species were not differentiated).
Praziquantel is used to treat infections caused by parasites such as liver flukes (worms) or schistosoma (blood fluke). These infections are also known as snail fever, schistosomiasis, or bilharziasis. Praziquantel may also be used for other worm infections as determined by your doctor. However, it will not work for pinworms or other roundworms.
Praziquantel belongs to the family of medicines called anthelmintics. Anthelmintics are used in the treatment of worm infections. Praziquantel works by causing severe spasms and paralysis of the worms' muscles. Some kinds of worms are then passed in the stool. However, you may not notice them since they are sometimes completely destroyed in the intestine.
praziquantel is available only with your doctor's prescription.
Once a medicine has been approved for marketing for a certain use, experience may show that it is also useful for other medical problems. Although these uses are not included in the product labeling, praziquantel is used in certain patients with the following medical conditions:
An anthelmintic used in most schistosome and many cestode infestations. [PubChem]
Use praziquantel as directed by your doctor. Check the label on the medicine for exact dosing instructions.
Ask your health care provider any questions you may have about how to use praziquantel.
There are specific as well as general uses of a drug or medicine. A medicine can be used to prevent a disease, treat a disease over a period or cure a disease. It can also be used to treat the particular symptom of the disease. The drug use depends on the form the patient takes it. It may be more useful in injection form or sometimes in tablet form. The drug can be used for a single troubling symptom or a life-threatening condition. While some medications can be stopped after few days, some drugs need to be continued for prolonged period to get the benefit from it.Use: Labeled IndicationsHelminths: Treatment of infections in patients ≥1 year caused by the following: All species of Schistosoma (eg, Schistosoma mekongi, Schistosoma japonicum, Schistosoma mansoni, Schistosoma haematobium) and the liver flukes Clonorchis sinensis/Opisthorchis viverrini
Off Label UsesNeurocysticercosis, parenchymal
Data from the phase II and phase III portions of a randomized, double blind, placebo-controlled study supports the use of praziquantel (in combination with albendazole) in the treatment of parenchymal neurocysticercosis.
The dosage recommended for the treatment of schistosomiasis is: 20 mg/kg bodyweight three times a day as a one day treatment, at intervals of not less than 4 hours and not more than 6 hours. The recommended dose for clonorchiasis and opisthorchiasis is: 25 mg/kg bodyweight three times a day as a one day treatment, at intervals of not less than 4 hours and not more than 6 hours. The tablets should be washed down unchewed with water during meals. Keeping the tablets or segments thereof in the mouth can reveal a bitter taste which can promote gagging or vomiting.
How suppliedPraziquantel (praziquantel) is supplied as a 600 mg white to orange tinged, film-coated, oblong tablet with three scores. The tablet is coded with “BAYER” on one side and “LG” on the reverse side. When broken, each of the four segments contains 150 mg of active ingredient so that the dosage can be easily adjusted to the patient's bodyweight.
Segments are broken off by pressing the score (notch) with thumbnails. If ¼ of a tablet is required, this is best achieved by breaking the segment from the outer end.
Praziquantel (praziquantel) is available in bottles of 6 tablets.

What other drugs will affect Praziquantel?
Concomitant administration of rifampin, a strong P450 inducer, with praziquantel is contraindicated and must be avoided. In a crossover study with a 2-week washout period, 10 healthy subjects ingested a single 40 mg/kg dose of praziquantel following pre-treatment with oral rifampin (600 mg daily for 5 days). Plasma praziquantel concentrations were undetectable in 7 out of 10 subjects. When a single 40 mg/kg dose of praziquantel was administered to these healthy subjects two weeks after discontinuation of rifampin, the mean praziquantel AUC and Cmax were 23% and 35% lower, respectively, than when praziquantel was given alone. In patients receiving rifampin, for example, as part of a combination regimen for the treatment of tuberculosis, alternative agents for schistosomiasis should be considered. However, if treatment with praziquantel is necessary, treatment with rifampin should be discontinued 4 weeks before administration of praziquantel. Treatment with rifampin can then be restarted one day after completion of praziquantel treatment.
Concomitant administration of other drugs that increase the activity of drug metabolizing liver enzymes (P450 inducers), for example, antiepileptic drugs (phenytoin, phenobarbital and carbamazepine), and dexamethasone, may also reduce plasma levels of praziquantel. Concomitant administration of drugs that decrease the activity of drug metabolizing liver enzymes (P 450 inhibitors), for example, cimetidine, ketoconazole, itraconazole, erythromycin may increase plasma levels of praziquantel.
Chloroquine, when taken simultaneously, may lead to lower concentrations of praziquantel in blood. The mechanism of this drug-drug interaction is unclear.
Grapefruit juice was reported to produce a 1.6-fold increase in the Cmax and a 1.9-fold increase in the AUC of praziquantel. However, the effect of this exposure increase on the therapeutic effect and safety of praziquantel has not been systematically evaluated.
