General

Folic acid, when administered in daily doses above 0.1mg, may obscure the detection of B12 deficiency (specifically, the administration of folic acid may reverse the hematological manifestations of B12 deficiency, including pernicious anemia, while not addressing the neurological manifestations). L-METHYLFOLATE CALCIUM Tablets may be less likely than folic acid to mask vitamin B12 deficiency.7,8 Folate therapy alone is inadequate for the treatment of a B12 deficiency.

A major depressive episode may be the initial presentation of bipolar disorder. It is generally believed, (although not established in controlled trials) that treating such an episode with an antidepressant alone may increase the likelihood of a precipitation of a mixed/manic episode in patients at risk for bipolar disorder. L-METHYLFOLATE CALCIUM Tablets is not an antidepressant; however, 5-MTHF has been shown to enhance antidepressant effects of known antidepressants.2 Caution is recommended in patients with a history of bipolar illness. Patients with depressive symptoms should be adequately screened to determine if they are at risk for bipolar disorder since mood elevation in this population is possible.

Interaction with Drugs

L-METHYLFOLATE CALCIUM Tablets contains folate, which may have interactions the following:

• Antiepileptic drugs (AED): The AED class including, but not limited to, phenytoin, carbamazepine, primidone, valproic acid, phenobarbital and lamotrigine have been shown to impair folate absorption and increase the metabolism of circulating folate. Additionally, concurrent use of folic acid has been associated with enhanced phenytoin metabolism, lowering the level of this AED in the blood and allowing breakthrough seizures to occur.9,10,12,15
• Capecitabine: Folinic acid (5-formyltetrahydrofolate) may increase the toxicity of Capecitabine.11
• Dihydrofolate Reductase Inhibitors (DHFRI): DHFIs block the conversion of folic acid to its active forms, and lower plasma and red blood cell folate levels. DHFIs include aminopterin, methotrexate, pyrimethamine, triamterene, and trimethoprim.12
• Fluoxetine: Fluoxetine exerts a noncompetitive inhibition of the 5-methyltetrahydrofolate active transport in the intestine.13
• Isotretinoin: Reduced folate levels have occurred in some patients taking isotretinoin,14
• Nonsteroidal Anti-inflammatory Drugs (NSAIDs): NSAIDs have been shown to inhibit some folate dependent enzymes in laboratory experiments. NSAIDs include ibuprofen, naproxen, indomethacin and sulindac.12
• Oral Contraceptives: Serum folate levels may be depressed by oral contraceptive therapy. 12
• Methylprednisolone: Reduced serum folate levels have been noted after treatment with methylpredinisolone. 12
• Pancreatic Enzymes: Reduced folate levels have occurred in some patients taking pancreatic extracts. 12
• Pentamidine: Reduced folate levels have been seen with prolonged intravenous pentamidine. 12
• Metformin treatment in patients with type 2 diabetes decreases serum folate.16,17
• Warfarin can produce significant impairment in folate status after a 6-month therapy.18
