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 Rejunex Forte 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 Rejunex Forte Injection

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