DRUG INTERACTIONS: Contraindicated with pyrimethamine (antimalarial) – folate may reduce drug effectiveness.

Caution with tetracycline antibiotics - concurrent administration with B2 and B12 may decrease the effectiveness of the medication. Separate dose by 2 hours.

Caution with chloramphenicol (broad spectrum antibiotic) – folic acid and B12 may impact drug metabolism. Separate dose by 2 hours.

Caution with anticholingeric drugs - these drugs reduce the

absorption of vitamin B2. Separate dose.

Caution with carbamazepine and primidone – vitamin B3 and folate may impact drug metabolism, resulting in increased drug levels in the body. Monitor use.

Caution with amiodarone – vitamin B6 may increase the risk of drug induced photosensitivity. Separate doses by at least 2 hours.

Caution with levodopa – vitamin B6 may reduce drug effects. However, this effect is prevented by the administration of a dopadecarboxylase inhibitor (e.g. benserazide, carbidopa) with levodopa, as is common clinical practice.

Caution with phenobarbital/phenobarbitone and phenytoin (anticonvulsants) - vitamin B6 and folate may reduce serum concentrations of these drugs.


B vitamins are stimulatory in nature. To avoid any sleep interference, avoid taking before bed.

Taking at night may result in more vivid dreams (vitamin B6).

Caution if there is a history of renal calculi (kidney stones) - vitamin C (ascorbic acid) may increase the risk of recurrence of calcium oxalate calculi.

SIDE EFFECTS: Supplemental B vitamins may cause nausea or mild gastrointestinal upset if taken on an empty stomach. Best taken with food to reduce the risk.

Riboflavin can impart a bright yellow colour to urine
