Description
Overview of the medicine
Medivit 5 mg Tablet contains Folic Acid, a B vitamin essential for red blood cell formation and DNA synthesis. It is used to treat and prevent folate deficiency and certain types of anemia.
Uses & Indications
Dosage
Adults
Typically 5 mg daily for 4 months; then 5 mg every 1-7 days depending on the underlying cause. For prophylaxis in pregnancy: 0.4-5 mg daily.
Elderly
Same as adult dose, but caution with potential B12 deficiency masking.
Renal_impairment
No specific dose adjustment required, but caution in dialysis patients due to potential loss.
How to Take
Oral. Can be taken with or without food.
Mechanism of Action
Folic acid is converted to tetrahydrofolate, which is a coenzyme for various metabolic processes including DNA synthesis, cell division, and red blood cell production.
Pharmacokinetics
Onset
Therapeutic effects may be seen within days, with resolution of megaloblastic anemia over weeks.
Excretion
Excreted in the urine as metabolites and unconverted folic acid, especially with high doses.
Half life
Approximately 30-90 minutes (for un-metabolized folic acid). For metabolites, it's longer.
Absorption
Readily absorbed from the gastrointestinal tract, primarily from the duodenum and jejunum. Peak plasma concentrations are reached within 1 hour.
Metabolism
Mainly in the liver to dihydrofolate and tetrahydrofolate. Also undergoes enterohepatic recirculation.
Side Effects
Contraindications
- •Untreated pernicious anemia or other vitamin B12 deficiencies (folic acid can mask B12 deficiency symptoms while neurological damage progresses)
- •Known hypersensitivity to folic acid or any component of the formulation
Drug Interactions
Phenytoin
Folic acid may decrease phenytoin levels, potentially leading to seizures. Monitor levels.
Methotrexate
Folic acid can antagonize the effects of methotrexate. Dosage adjustments may be needed.
Sulfasalazine
May decrease folic acid absorption.
Storage
Store in a cool, dry place, below 30°C. Protect from light and moisture. Keep out of reach of children.
Overdose
Folic acid is generally well-tolerated even at high doses. Symptoms are rare but may include gastrointestinal disturbances. Treatment is supportive.
Pregnancy & Lactation
Generally considered safe and essential during pregnancy to prevent neural tube defects. Also safe during lactation, as folate is excreted in breast milk in small amounts.
