How Siglyn M 100/1000 Tablet works

Siglyn M 100/1000 Tablet ER is a combination of two medicines: sitagliptin and metformin. Sitagliptin helps your pancreas produce more insulin, facilitates effective use of insulin by the body, and reduces excess sugar that your liver makes. Metformin is a biguanide that lowers glucose production in the liver, delays glucose absorption from the intestines, and increases the body's sensitivity to insulin. Together, they provide better control of blood sugar.

Warnings and precautions

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.

Do not take Siglyn M 100/1000 if

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.

Interactions with other medicines

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.

How to store Siglyn M 100/1000 Tablet

Store below 30°C in the original pack, away from direct sunlight and moisture. Keep out of the reach of children.

Expert advice for Siglyn M 100/1000 Tablet

Take Siglyn M 100/1000 Tablet ER with food to lower your chance of having an upset stomach. Take it in addition to regular exercise and a healthy diet to lower blood sugar levels. The chances of weight gain and low blood sugar are lower than with 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 Siglyn M 100/1000 Tablet ER may cause a rare but serious condition called lactic acidosis, which is an excess of lactic acid in the blood.
