Metformin HCL 850mg-Glycoheal Tablets

Q1: What is Metformin 850mg used for?

Metformin HCl 850mg is a standard maintenance dose for established type 2 diabetes, providing stronger blood sugar lowering than 500mg for patients who need better glycemic control or have been on Metformin long-term.

Q2: How does Metformin 850mg differ from 500mg?

The 850mg dose delivers a higher amount of Metformin per tablet, providing more hepatic glucose suppression. Many patients on twice-daily 850mg achieve better HbA1c than on three-times-daily 500mg, with fewer daily doses improving adherence.

Q3: When should I take Metformin 850mg?

Take two to three times daily with meals. The most common schedule is 850mg with breakfast and dinner (twice daily). Taking with food reduces nausea and GI upset.

Q4: What is the maximum daily dose?

The maximum recommended daily dose is 2550mg (three 850mg tablets). Most patients reach adequate control at 1700mg (two tablets). Higher doses provide modest additional benefit but more GI side effects.

Q5: Can Metformin 850mg cause low blood sugar?

Metformin monotherapy rarely causes hypoglycemia. Unlike sulfonylureas, it does not stimulate insulin secretion. Hypoglycemia risk only increases when combined with insulin or sulfonylureas.

Q6: What are the most common side effects at 850mg?

GI disturbances (diarrhea, nausea, abdominal cramping) and metallic taste are most common, especially when starting. These typically improve after 2–4 weeks. Starting at 500mg and titrating up reduces GI intolerance.

Q7: What cardiovascular benefits does Metformin provide?

The UKPDS trial demonstrated that Metformin reduces cardiovascular events and all-cause mortality in overweight type 2 diabetics, independent of glucose lowering. This makes it a preferred first-line choice for most patients.

Q8: Is Metformin 850mg safe for kidney disease?

Not recommended if eGFR is below 30 ml/min. Use with caution between 30–45 ml/min. Hold before iodinated contrast procedures or major surgery; restart only after confirming normal renal function.

Q9: Can I take Metformin 850mg during pregnancy?

Under some clinical guidelines Metformin is used in gestational diabetes, but insulin remains the preferred standard. Discuss with your doctor the most appropriate management during pregnancy.

Q10: Does long-term Metformin use deplete B12?

Yes. Long-term use reduces vitamin B12 absorption. Periodic B12 monitoring and supplementation may be needed, especially if you experience numbness, tingling, or fatigue.

Q11: How should I store Metformin 850mg?

Store below 25°C in the original packaging, away from moisture. Keep out of reach of children. Do not use after the expiry date.

Q12: Do I need a prescription?

Yes. Metformin 850mg requires a prescription. Your doctor will assess kidney function, cardiac status, and current diabetes control before prescribing.
