FOLIC ACID oral solution is indicated for the treatment of megaloblastic anemias due to folic acid deficiency in adult and pediatric patients. FOLIC ACID oral solution is a folate analog indicated for the treatment of megaloblastic anemias due to folic acid deficiency in adult and pediatric patients. ( 1 )

FOLIC ACID oral solution is contraindicated in patients with a history of a hypersensitivity reaction to folic acid or any of the ingredients of QUIOFIC [see Description (11) ]. FOLIC ACID oral solution is contraindicated in patients with a history of a hypersensitivity reaction to folic acid or any of the ingredients of QUIOFIC. ( 4 )

Folic acid in doses above 0.1 mg daily may obscure pernicious anemia in that hematologic remission can occur while neurologic manifestations remain progressive. This may result in severe nervous system damage before the correct diagnosis is made. ( 5.1 )

5.1Risk of Obscuring Diagnosis of Pernicious Anemia

The use of single-agent FOLIC ACID oral solution (without the use of vitamin B12) is not recommended for the treatment of pernicious anemia and other megaloblastic anemias in which vitamin B 12 is deficient. Folic acid in doses above 0.1 mg daily may obscure pernicious anemia in that hematologic remission can occur while neurologic manifestations remain progressive. There is a potential danger in administering folic acid to patients with undiagnosed anemia, since folic acid may obscure the diagnosis of pernicious anemia by alleviating the hematologic manifestations of the disease while allowing the neurologic complications to progress.

This may result in severe nervous system damage before the correct diagnosis is made. Adequate doses of vitamin B 12 may prevent, halt, or improve the neurologic changes caused by pernicious anemia.

Anticonvulsant action of phenytoin is antagonized by folic acid. ( 7 ) Multiple drug classes, including anticonvulsants, antibiotic/antimicrobial agents, folate antagonists, GI-binding agents, and oral contraceptives, may reduce folic acid absorption or folate levels. ( 7 )
