Warnings and precautions

Tingling, numbness or burning in the hands and feet should be assessed by a doctor rather than self-treated — a supplement does not address the cause. Folic acid can mask a vitamin B12 deficiency while nerve damage continues, so B12 should be checked before taking folic acid long term. Bright yellow urine after a B-complex dose is expected and harmless.

Do not take Rejunuron if

Not for anyone with a known allergy to this medicine or to any ingredient in the pack.

Interactions with other medicines

Long-term metformin, acid-reducing medicines and some anti-epileptics lower B12 or folate levels. Tell your doctor if you take levodopa, as vitamin B6 can reduce its effect.

How to store Rejunuron Injection 1 ml

Store as printed on the carton — some injections need refrigeration and must not be frozen. Keep out of the reach of children.
