Pharmacology

Methylfolate, or L-methylfolate, is the active form of folate in the body, which can be transported into peripheral tissues and across the blood-brain barrier. Folate is necessary for formation of numerous coenzymes in many metabolic systems, particularly for purine, pyrimidine, and nucleoprotein synthesis, and maintenance in erythropoiesis; stimulates WBC and platelet production in folate deficiency anemia.

Use: Labeled Indications

Medical food for the nutritional requirements of patients with suboptimal L-methylfolate and have major depressive disorder or who have or are at risk for hyperhomocysteinemia and have schizophrenia

Note: A medical food is formulated to be administered enterally under the supervision of a physician and is intended for the specific dietary management of a disease or condition for which distinctive nutritional requirements are established by medical evaluation. Medical foods are not drugs and, therefore, are not subject to any FDA regulatory requirements that specifically apply to drugs (eg, requirement for written/oral prescription prior to dispensing, premarket review or approval, proof of safety and efficacy).

Patient Education

• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)

• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
