How to take this drug

For tablets or capsules, adults usually take 1 to 2 tablets daily, preferably with food to help your body absorb the vitamins better. For the syrup like Avrobion, follow the dose on the bottle — usually 1 to 2 teaspoonfuls (5-10ml) daily. Injections are given by a healthcare professional, usually when your body needs the vitamins urgently or you cannot swallow.

What if I Miss a Dose?

If you miss a dose, just take it as soon as you remember. If it is almost time for your next dose, skip the missed one and continue as normal. No need to double up — these are vitamins, not antibiotics.

What to watch out for

Buy only from reputable pharmacies — avoid buying vitamins from roadside sellers or open markets as they may be expired or fake. Do not take more than the recommended dose thinking it will work faster — excess vitamins can cause problems. If you are on TB medication, tell your doctor so they can adjust your B-Complex dose properly.

Common Side Effects

Bright yellow urine (this is normal and harmless — it is just excess Riboflavin leaving your body)
mild stomach upset or nausea
slight warmth or flushing of the skin
mild diarrhea if taken on an empty stomach

Serious Side Effects

Severe allergic reaction such as swelling of the face
lips
or throat and difficulty breathing — go to the hospital immediately. Severe skin rash or itching all over the body also needs urgent medical attention.

Drug Interactions

Levodopa (used for Parkinson's disease) — Pyridoxine (B6) can reduce its effectiveness. Certain antibiotics like isoniazid (used for TB treatment) can deplete B vitamins, so your doctor may prescribe B-Complex alongside TB drugs. Alcohol reduces your body's ability to absorb B vitamins, so reduce alcohol intake while using this supplement.
