Eternex M 1000 is used for treatment of Type 2 diabetes mellitus.
Medically reviewed by Dr. Balaji Krishnan, MBBS · Updated September 2026
Eternex M 1000 contains Metformin (1000mg) + Teneligliptin (20mg). It belongs to the Biguanide and DPP-4 inhibitor class of medicines.
Treatment of Type 2 diabetes mellitus
Eternex-M 1000 Tablet SR is a combination of two antidiabetic medicines:
Take this medicine in the dose and duration as advised by your doctor. Swallow it as a whole. Do not chew, crush or break it. Eternex-M 1000 Tablet SR should be taken with or after food.
Take it exactly as your doctor prescribed. Do not change the dose or stop early on your own.
If you miss a dose of Eternex-M 1000 Tablet SR, take it as soon as possible. However, if it is almost time for your next dose, skip the missed dose and go back to your regular schedule. Do not double the dose.
An overdose of this medicine can cause a dangerous build-up of acid in the blood, with vomiting, severe weakness and laboured breathing. It may cause low blood sugar, particularly if you also take other diabetes medicines. Do not wait for symptoms to appear — go to the nearest emergency department and take the pack or strip with you.
Most side effects of Eternex M are mild and settle as the body adjusts. Reported side effects include:
Stop the medicine and seek help immediately for a rash, swelling of the face or lips, wheezing or difficulty breathing. Tell your doctor about any side effect that persists or worries you.

Stomach upset is common in the first two weeks and usually settles; taking it with food helps. Tell your doctor before any surgery or a scan that uses contrast dye — this medicine is usually stopped for a short time around them. Stop and seek urgent care if you develop deep rapid breathing, severe weakness, muscle pain or vomiting with cold clammy skin. This is rare but serious. Long-term use can lower vitamin B12, so your doctor may check it from time to time. Stop and see a doctor urgently if you get severe, persistent abdominal pain that spreads to your back, with or without vomiting. Tell your doctor if you develop severe or disabling joint pain. Blisters or peeling of the skin should be reported promptly.
Not for anyone with a known allergy to this medicine or to any ingredient in the pack. Not for people with severe kidney disease, severe liver disease, or an acute illness causing dehydration. Not for people who have had diabetic ketoacidosis. Not for type 1 diabetes or for diabetic ketoacidosis.
Tell your doctor about water tablets, steroids, and any contrast dye scan. Alcohol increases the risk of the rare acid build-up and should be limited. Low blood sugar is more likely when this is combined with a sulfonylurea or insulin; your doctor may lower that dose.
Store below 30°C in the original pack, away from direct sunlight and moisture. Keep out of the reach of children.
You have been prescribed this combination medicine as it can control blood sugar better than metformin alone. Take it in addition to regular exercise and a healthy diet to lower levels of blood sugar. Take it with food to lower your chance of having an upset stomach. Chances of weight gain and low blood sugar are lesser as compared to other diabetes medicines. Monitor your blood sugar level regularly while you are taking this medicine. Inform your doctor about your diabetes treatment if you are due to have surgery under a general anesthetic. Tell your doctor immediately if you experience any deep or rapid breathing, persistent nausea, vomiting, and stomach pain as Eternex-M 1000 Tablet SR may cause a rare but serious condition called lactic acidosis, which is an excess of lactic acid in the blood.
Medicines with the same active ingredient (Metformin (1000mg) + Teneligliptin (20mg)). Ask your doctor or pharmacist before switching brands.
