Sitomni-M-OD 100/500 FAQ: Patient Questions Answered
Sitomni-M-OD 100/500: Sitagliptin Phosphate & Metformin Hydrochloride Tablets
Straight answers to the questions patients ask most often about Sitomni-M-OD 100/500, grouped into what it is, taking it, staying safe, and everyday practical matters.
About the medicine
What exactly is Sitomni-M-OD 100/500? It is a film-coated prescription tablet marketed by EMK Omni Pharma that contains Sitagliptin 100 mg and Metformin Hydrochloride 500 mg, made for the company at GMP-certified units.
Why two drugs in one tablet? Because the two work differently. Metformin reduces glucose output from the liver and improves insulin sensitivity, while sitagliptin extends the action of the gut hormones that prompt insulin release after meals. One tablet is also easier to remember than two.
What does OD mean on the pack? OD indicates the once-daily design of the tablet. Your actual schedule is whatever your doctor writes on the prescription.
Is it a new type of medicine? No. Metformin has been used in diabetes care for many decades, and DPP-4 inhibitors such as sitagliptin have been part of standard type 2 diabetes practice for years.
Taking Sitomni-M-OD 100/500
Before or after food? Generally with food or straight after a meal, because the metformin part can irritate an empty stomach.
Can I break the tablet? No. Swallow it whole with water. If swallowing is hard, speak to your doctor instead of splitting it.
I forgot yesterday's dose. Do I take two today? No. Take the next dose at the usual time and carry on. Doubling up does not help and can cause stomach upset.
Can I change the time of day? A change of timing should be discussed with your doctor or pharmacist, and once you settle on a time, keep it consistent.
Does it work immediately? It begins acting from the first doses, but the true measure of control is HbA1c and readings over weeks, which is why reviews are scheduled rather than immediate.
Safety questions people ask
Will it cause low blood sugar? On its own it is less likely to. The risk goes up if it is prescribed with a sulfonylurea or insulin, or if meals are skipped. Learn the signs of a low and how to treat one.
Is it safe for my kidneys? Metformin needs working kidneys to be cleared, so your doctor checks kidney function before starting and periodically afterwards. It is not prescribed when function is too low.
Can I take it while pregnant or breastfeeding? This needs a specific decision from your doctor. Tell them as early as possible if you are pregnant or planning to be.
Can I drink alcohol? Best avoided or kept minimal. Alcohol upsets glucose control and increases the risk of a rare but serious metformin complication.
Is it addictive? No. It is a long-term treatment, which is different from dependence. Continue it as long as your doctor advises.
Practical and everyday matters
Where can I buy it? Only from a licensed chemist, against a prescription from a registered medical practitioner, since it carries Schedule G and Schedule H warnings. Ask for a bill and check the batch, expiry and MRP printed on the pack.
How should I store it at home? In a cool, dry, dark cupboard, protected from light, away from bathroom humidity and away from children.
Can I carry it while travelling? Yes. Keep it in hand baggage with a copy of the prescription and take a few extra days' supply.
Can I give a strip to a relative with diabetes? No. Prescriptions are individual and depend on kidney function, other medicines and sugar readings. Sharing is unsafe.
