Common use

Glucophage SR is a sustained release formulation of metformin, one of the most widely prescribed medications for type 2 diabetes worldwide. This extended release tablet belongs to the biguanide class of antidiabetic agents and is specifically designed to provide steady, continuous blood sugar control throughout the day. If you are looking to buy Glucophage SR online, this trusted diabetes treatment helps millions manage their condition effectively with once-daily dosing convenience.

Metformin sustained release works through multiple mechanisms to combat high blood glucose levels. It reduces the concentration of glucose in the blood by suppressing excess glucose production in the liver (hepatic gluconeogenesis), decreasing absorption of glucose from the gastrointestinal tract, and enhancing glucose utilization in peripheral tissues — particularly skeletal muscle. These combined actions make Glucophage SR a cornerstone of type 2 diabetes management.

A significant advantage of this Glucophage SR generic formulation is its ability to stabilize or reduce body weight — a welcome benefit since many patients with type 2 diabetes struggle with obesity. Unlike sulfonylureas and insulin, metformin SR does not cause hypoglycemic reactions when used as monotherapy, because its therapeutic effect depends on the presence of circulating insulin. This makes it a safer first-line option for blood sugar control.

Glucophage SR also offers cardiovascular benefits. It has been shown to improve fibrinolytic properties of blood, potentially reducing the risk of blood clot formation. This medication is prescribed for the treatment of type 2 diabetes in adults, particularly in patients for whom treatment with sulfonylurea drugs has been ineffective — especially in cases accompanied by obesity and insulin resistance.



Dosage and direction

Do not take Glucophage SR unless it has been prescribed by your doctor, and do not exceed the recommended dose. The extended release tablet should be swallowed whole with food — do not crush, break, or chew the tablet, as this would destroy the sustained release mechanism.

When you buy metformin SR, typical starting doses for adults with type 2 diabetes are 500 mg once daily with the evening meal. Based on blood glucose monitoring results, your doctor may gradually increase the dose. The maximum recommended daily dose of Glucophage SR is 2000 mg, taken as a single dose or divided into two doses. Dosage adjustments should be guided by regular blood sugar testing to achieve optimal diabetes treatment outcomes.



Precautions

Metformin sustained release can, in rare cases, cause a life-threatening condition called lactic acidosis. This is characterized by weakness, increasing sleepiness, slow heartbeat, cold feeling, muscle pain, abdominal pain, shortness of breath, lightheadedness, and fainting. If you experience any of these symptoms while taking Glucophage SR, seek immediate medical attention.

Be alert to symptoms of low blood sugar (hypoglycemia), which may occur if you are taking other diabetes treatment medications alongside metformin. These symptoms include hunger, confusion, irritability, drowsiness, headache, weakness, fast heartbeat, tremors, sweating, and seizures. Always keep a source of fast-acting sugar readily available.

Avoid drinking alcohol while taking Glucophage SR, as alcohol increases the risk of lactic acidosis and can interfere with blood sugar control. Regular monitoring of kidney function, blood glucose, and hemoglobin A1c levels is recommended for all patients using this biguanide medication.



Contraindications

Glucophage SR is contraindicated in patients with hypersensitivity to metformin, hyperglycemic coma, diabetic ketoacidosis, kidney failure (eGFR below 30 mL/min), liver disease, heart failure, acute myocardial infarction, respiratory failure, severe dehydration, serious infectious diseases, extensive surgery or trauma, chronic alcoholism, severely reduced-calorie diet (less than 1000 kcal/day), or a history of lactic acidosis.

This extended release diabetes treatment should be temporarily discontinued 2 days before any planned surgery, radioisotope studies, X-ray examinations with contrast media, or CT scanning. Glucophage SR is contraindicated during pregnancy and breastfeeding. Special caution is warranted in patients over 60 years of age or those engaged in heavy physical labor, as the risk of lactic acidosis increases in these populations.



Side effects

The most common side effects of Glucophage SR include nausea, vomiting, gas, bloating, diarrhea, abdominal discomfort, and decreased appetite. These gastrointestinal effects are often most pronounced when starting treatment and typically improve over time. The sustained release formulation is specifically designed to reduce these side effects compared to immediate-release metformin.

Seek emergency medical help if you develop symptoms of lactic acidosis: weakness, increasing drowsiness, slow heartbeat, cold sensation, shortness of breath, abdominal or muscle pain, lightheadedness, or fainting. Allergic reactions including hives, swelling, and skin rash are possible but uncommon. Long-term use of metformin may reduce vitamin B12 absorption, so periodic monitoring is recommended.



Drug interactions

Cimetidine (Tagamet) increases blood levels of metformin by affecting its renal elimination. Glucophage SR is not compatible with alcohol — this combination significantly raises the risk of lactic acidosis. Concomitant administration with indirect anticoagulants and Cimetidine should be done with caution.

Metformin SR enhances the metabolism of Furosemide. Derivatives of sulfonylurea, insulin, acarbose, MAO inhibitors, oxytetracycline, cyclophosphamide, and salicylates increase the blood sugar control effects of Glucophage SR. A decrease in metformin's hypoglycemic effect may result from co-administration with thyroid medications, oral contraceptives and other hormones, Epinephrine, Glucagon, thiazide diuretics, and nicotinic acid derivatives. Iodinated contrast media used in radiological studies can impair kidney function and should be avoided around the time of Glucophage SR administration.



Missed dose

If you forget to take your Glucophage SR dose, take it as soon as you remember — but only if it is taken with food. If it is nearly time for your next scheduled dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose of this diabetes treatment to make up for a missed one.



Overdose

Symptoms of Glucophage SR overdose include signs of severe hypoglycemia: hunger, confusion, irritability, drowsiness, headache, weakness, tremors, sweating, fast heartbeat, and seizures. In severe cases, lactic acidosis may develop. If you suspect an overdose, seek emergency medical attention immediately. Keep a source of fast-acting sugar available at all times while taking metformin sustained release.



Storage

Store Glucophage SR at room temperature between 20-25 degrees C (68-77 degrees F). Keep away from moisture, heat, and direct sunlight. Do not store in the bathroom. Keep this medication out of reach of children and pets.
