Drug Information for Folic Acid Tablets, (Amneal Pharmaceuticals, LLC): OVERDOSAGE

Except during pregnancy and lactation, folic acid should not be given in therapeutic doses greater than 0.4 mg daily until pernicious anemia has been ruled out. Patients with pernicious anemia receiving more than 0.4 mg of folic acid daily who are inadequately treated with vitamin B₁₂ may show reversion of the hematologic parameters to normal, but neurologic manifestations due to vitamin B₁₂ deficiency will progress. Doses of folic acid exceeding the Recommended Dietary Allowance (RDA) should not be included in multivitamin preparations; if therapeutic amounts are necessary, folic acid should be given separately.
