Rejumet Tablet belongs to the group of medications called ‘anti-diabetic’ used in the treatment of Type 2 diabetes mellitus. Type 2 diabetes mellitus is a chronic or life-long condition in which blood sugar or glucose levels rise more than normal. It occurs when the body does not produce enough insulin (metabolizes glucose), or if produced, it cannot function properly in the body.

Rejumet Tablet is a combination of two medicines, namely: Metformin and Methylcobalamin. Metformin acts by decreasing liver glucose production and intestinal glucose uptake. It may deplete vitamin B12 levels. So, it is taken with methylcobalamin that can treat vitamin B12 deficiency. Thus, Rejumet Tablet does not cause a sudden lowering of the blood glucose level or significant hypoglycemia.

You should take this medicine as prescribed by your doctor. You may experience side-effects of such as changes in taste, nausea (feeling sick), vomiting (falling sick), diarrhoea, headache, anorexia (loss of appetite), and sweating. Inform your doctor if any of these side-effects persist or worsen.

Do not take Rejumet Tablet if you are allergic to any of its contents. Before taking Rejumet Tablet , inform your doctor if you have liver problems, severe kidney failure, uncontrolled diabetes, dehydration due to severe diarrhoea or vomiting, severe infections, acute heart failure or heart attack, and alcoholism. Also, inform your doctor if you are pregnant, planning to become pregnant, or breastfeeding. 

Rejumet Tablet is a combination of two medicines, namely: Metformin and Methylcobalamin. Metformin acts by decreasing liver glucose production and intestinal glucose uptake. Methylcobalamin reduces vitamin B12 deficiency. Rejumet Tablet does not cause significant hypoglycemia (sudden lowering of the blood glucose level). It is usually preferred in obese patients with diabetes as it may cause weight loss and lowers the complications of diabetes.  

Rejumet Tablet may cause a rare and serious side-effect ‘lactic acidosis’ (buildup of lactic acid in the blood), characterized by abdominal pain, muscle cramps, vomiting, severe fatigue, and difficulty breathing. It is a life-threatening condition that requires immediate medical attention. Inform your doctor if you have any severe liver or kidney problems as their normal functioning is required to eliminate excess lactic acid from the body.  Do not consume excess alcohol as it increases the risk of lactic acidosis. It should be used with caution in patients with heart diseases as it increases the risk of heart failure. If you have dehydration (severe loss of body fluids) due to severe vomiting, diarrhoea, exposure to heat, or fever, stop taking Rejumet Tablet and immediately seek medical attention. Rejumet Tablet may cause electrolyte imbalance, so taking this medicine during dehydration can worsen the condition.  

Beware of hypoglycemia (low blood sugar level) symptoms include sweating, dizziness, palpitations, shivering, intense thirst, dry mouth, dry skin, frequent urination, etc. Whenever you experience these symptoms, try to eat 5-6 candies or 3 glucose biscuits or 3 teaspoons of honey/sugar and get in touch with your doctor. Make sure you carry these with you at all times, especially for long travels.
