What is the most important information I should know about Lysatone Plus?
You should not use this medication if you are allergic to cobalt, or if you have Leber's disease. Lysatone Plus can lead to optic nerve damage (and possibly blindness) in people with Leber's disease.
To treat pernicious anemia, you will have to use this medication on a regular basis for the rest of your life. Not using the medication can lead to irreversible nerve damage in your spinal cord.
Pernicious anemia is also treated with folic acid to help maintain red blood cells. However, folic acid will not treat Vitamin B12 deficiency and will not prevent possible damage to the spinal cord. Use all of your medications as directed.
Avoid eating or drinking hot foods or liquids within 1 hour before or after using the nasal form of this medication.
Tell your doctor if you develop nasal congestion, a cold, or allergies. The nasal spray may not work as well if you are congested.
Your dose needs may change if you become pregnant, if you breast-feed, or if you eat a vegetarian diet. Tell your doctor about any changes in your diet or medical condition.

What are the possible side effects of Lysatone Plus?
The incidence of adverse experiences described in the Table below are based on data from a short-term clinical trial in vitamin B12 deficient patients in hematologic remission receiving Lysatone Plus (Lysatone Plus, USP) Gel for Intranasal Administration (N=24) and intramuscular vitamin B12 (N=25). In the pharmacokinetic study comparing Lysatone Plus Nasal Spray and Lysatone Plus Nasal Gel, the incidence of adverse events was similar.
The intensity of the reported adverse experiences following the administration of Lysatone Plus (Lysatone Plus, USP) Gel for Intranasal Administration and intramuscular vitamin B12 were generally mild. One patient reported severe headache following intramuscular dosing. Similarly, a few adverse experiences of moderate intensity were reported following intramuscular dosing (two headaches and rhinitis; one dyspepsia, arthritis, and dizziness), and dosing with Lysatone Plus (Lysatone Plus, USP) Gel for Intranasal Administration (one headache, infection, and paresthesia).
The majority of the reported adverse experiences following dosing with Lysatone Plus (Lysatone Plus, USP) Gel for Intranasal Administration and intramuscular vitamin B12 were judged to be intercurrent events. For the other reported adverse experiences, the relationship to study drug was judged as "possible" or "remote". Of the adverse experiences judged to be of "possible" relationship to the study drug, anxiety, incoordination, and nervousness were reported following intramuscular vitamin B12 and headache, nausea, and rhinitis were reported following dosing with Lysatone Plus (Lysatone Plus, USP) Gel for Intranasal Administration.
The following adverse reactions have been reported with parenteral vitamin B12:
Generalized: Anaphylactic shock and death.
Cardiovascular: Pulmonary edema and congestive heart failure early in treatment; peripheral vascular thrombosis.
Hematological: Polycythemia vera.
Gastrointestinal: Mild transient diarrhea.
Dermatological: Itching; transitory exanthema.
Miscellaneous: Feeling of swelling of the entire body.
Lysatone Plus Nasal Spray is indicated for the maintenance of normal hematologic status in pernicious anemia patients who are in remission following intramuscular vitamin B12 therapy and who have no nervous system involvement.
Lysatone Plus Nasal Spray is also indicated as a supplement for other vitamin B12 deficiencies, including:
I. Dietary deficiency of vitamin B12 occurring in strict vegetarians (Isolated vitamin B12 deficiency is very rare).
II. Malabsorption of vitamin B12 resulting from structural or functional damage to the stomach, where intrinsic factor is secreted, or to the ileum, where intrinsic factor facilitates vitamin B12 absorption. These conditions include HIV infection, AIDS, Crohn's disease, tropical sprue, and nontropical sprue (idiopathic steatorrhea, gluten-induced enteropathy). Folate deficiency in these patients is usually more severe than vitamin B12 deficiency.
III. Inadequate secretion of intrinsic factor, resulting from lesions that destroy the gastric mucosa (ingestion of corrosives, extensive neoplasia), and a number of conditions associated with a variable degree of gastric atrophy (such as multiple sclerosis, HIV infection, AIDS, certain endocrine disorders, iron deficiency, and subtotal gastrectomy). Total gastrectomy always produces vitamin B12 deficiency. Structural lesions leading to vitamin B12 deficiency include regional ileitis, ileal resections, malignancies, etc.
IV. Competition for vitamin B12 by intestinal parasites or bacteria. The fish tapeworm (Diphyllobothrium latum) absorbs huge quantities of vitamin B12 and infested patients often have associated gastric atrophy. The blind loop syndrome may produce deficiency of vitamin B12 or folate.
V. Inadequate utilization of vitamin B12. This may occur if antimetabolites for the vitamin are employed in the treatment of neoplasia.
It may be possible to treat the underlying disease by surgical correction of anatomic lesions leading to small bowel bacterial overgrowth, expulsion of fish tapeworm, discontinuation of drugs leading to vitamin malabsorption, use of a gluten-free diet in non-tropical sprue, or administration of antibiotics in tropical sprue. Such measures remove the need for long-term administration of vitamin B12.
Requirements of vitamin B12 in excess of normal (due to pregnancy, thyrotoxicosis, hemolytic anemia, hemorrhage, malignancy, hepatic and renal disease) can usually be met with intranasal or oral supplementation.
Lysatone Plus Nasal Spray is not suitable for vitamin B12 absorption test (Schilling Test).
Lysatone Plus nasal spray contains Cyanocobalamin, a man-made form of vitamin B12. Vitamin B12 is important for growth, cell reproduction, blood formation, and protein and tissue synthesis.
Lysatone Plus nasal spray is used to treat vitamin B12 deficiency in people with pernicious anemia and other conditions.
Lysatone Plus nasal spray is usually given after treatment with an injection form of this medicine.
Lysatone Plus may also be used for purposes not listed in this medication guide.
Lysatone Plus (commonly known as Vitamin B12) is the most chemically complex of all the vitamins. Lysatone Plus's structure is based on a corrin ring, which, although similar to the porphyrin ring found in heme, chlorophyll, and cytochrome, has two of the pyrrole rings directly bonded. The central metal ion is Co (cobalt). Lysatone Plus cannot be made by plants or by animals, as the only type of organisms that have the enzymes required for the synthesis of Lysatone Plus are bacteria and archaea. Higher plants do not concentrate Lysatone Plus from the soil and so are a poor source of the substance as compared with animal tissues. Lysatone Plus is naturally found in foods including meat (especially liver and shellfish), eggs, and milk products. [HMDB]
