PaxLyte Prescribing Information

Warnings and Precautions

Folic Acid alone is improper therapy in the treatment of pernicious anemia and other megaloblastic anemias where vitamin B12 is deficient. Daily doses of 0.1 mg or more of folic acid (vitamin B9) may obscure pernicious anemia. Hematologic improvement can occur while neurological damage progresses. Exclusive use of folic acid to treat vitamin B12-deficient macrocytic anemia can lead to progressive and irreversible neurological damage. Vitamin B12 deficiency allowed to progress for over 3 months may cause permanent spinal cord lesions. Doses of vitamin B12 exceeding 10 mcg daily may produce hematologic response in patients with vitamin B9 deficiency. Indiscriminate administration may mask the true diagnosis.

Adverse Reactions/Side Effects

Mild transient diarrhea, polycythemia vera, itching, transitory exanthema, feeling of swelling of entire body may occur with administration of vitamin B12. Allergic sensitization has been reported following both oral and parenteral administration of vitamin B9.

PaxLyte Description

PaxLyte is an orally administered prescription vitamin for therapeutic use formulated for patients who are under specific direction and monitoring of homocysteine (HCY) status by a physician. It is specifically formulated for patients with deficiencies in folate and vitamin B12, including those with genetic polymorphisms affecting homocysteine metabolism. A recent study+ suggested that PaxLyte was effective in lowering homocysteine levels in patients that are positive for MTHFR (methylenetetrahydrofolate reductase polymorphism).
