FAQs

Mecobalamin is a synthetic form of vitamin B12. It works by increasing vitamin B12 levels in your body, assisting in the treatment of anaemias and nerve problems.

Pain, swelling, or itchy skin where your injection was administered; these symptoms are often minimal and should last only a few hours. If the discomfort is affecting you, you might seek a healthcare expert for a mild pain reliever.

When your vitamin B12 (Mecobalamin) blood levels return to normal, you may be able to discontinue taking Mecobalamin. However, if your diet lacks vitamin B12 or you cannot absorb enough vitamin B12 from food, you may need to take it for the rest of your life.

Vitamin B12 deficiency occurs when you don't have enough Methylcobalamin or Mecobalamin levels in the body. You can include natural Vitamin B12 sources like eggs, beef, liver, chicken, trout, salmon, tuna, fish, clams, fortified breakfast cereal, low-fat milk, yoghurt, and cheese in your diet to treat the deficiency. If you still have low levels of B12, please consult your doctor.

Diarrhoea might be a side-effect of Happy Nerve 500Mcg/1Ml Inj. Drink lots of fluids and eat food rich in fibre. If you find blood in your stools (tarry stools) or if you experience excess diarrhoea, consult your doctor.

If you miss a dose, take it as soon as you remember. However, if it is time for the next scheduled dose, skip the missed dose and follow your usual dosage.
