Glucophage (Metformin)

4.79 / 284

Glucophage is one of the most common medicines with antihyperglycemic activity. The drug is known for its reliability in lowering blood sugar levels to a safe range. The mechanism of action of Glucophage differs from that of other oral sugar-lowering medications.

The main task of Glucophage is to control the optimal blood glucose level over a long period of time. In addition, it provides control over hyperglycemia and, after eating, does not allow glucose levels to rise to a critical level.

In various clinical trials and post-marketing studies, Glucophage has shown a good safety profile for various groups of patients with type 2 diabetes of varying severity.

  • Manufacturer: Merck.

Glucophage and its active substance Metformin

Metformin is the medical name for the active ingredient of Glucophage tablets. In addition, the pills contain excipients that provide the necessary dissolution rate in a liquid medium.

Due to the unique molecular structure, Glucophage compares favorably with other hypoglycemic agents. The drug does not cause:

  • Hypoglycemia (decrease in blood sugar levels to critically low values);
  • Hyperinsulinemia (high levels of blood insulin).

These are two obvious advantages over some other drugs with a lower degree of pharmacological safety. Glucophage tablets can contain 300 mg, 500 mg, 850 mg or 1000 mg of Metformin. This active substance is classified as an antihyperglycemic agent. It acts primarily in the liver by reducing glucose production.

The drug has several therapeutic effects:

  • It improves glucose tolerance by reducing blood sugar levels before, during and after meals;
  • It does not stimulate insulin production, the secretion of this hormone remains unchanged;
  • It reduces hepatic gluconeogenesis (synthesis of glucose from non-carbohydrate components);
  • It increases insulin sensitivity in skeletal muscles and other tissues;
  • It slows down and reduces the absorption of glucose by the walls of the small intestine.

During treatment, a beneficial effect on lipid metabolism is also observed. The level of triglycerides is reduced when measured on an empty stomach. High levels of this type of fat increase the risk of damage to large blood vessels (atherosclerosis) and other cardiovascular diseases.

The combination of all therapeutic effects of the drug allows you to achieve adequate glycemic control.

Indications for use

The antihyperglycemic effects of Glucophage have been experimentally demonstrated and clinically confirmed. This medicine is safe and highly effective for therapy of:

  • Type 2 diabetes.

The purpose of using this medication is to help people overcome the existing problems with high blood sugar level and improve long-term well-being.

It is suitable for overweight patients, as one of its effects (not for all patients) is loss of appetite. Long use of the drug may help reduce the risk of complications associated with hyperglycemia.

Where to buy Glucophage? Possible options

Metformin has proven itself good for the treatment of type 2 diabetes. However, more and more people want to buy Glucophage online because this option is a lot more profitable.

For example, the cost of one Metformin tablet online in our pharmacy is 3-4 times lower than in city pharmacies. At the same time, we offer original tablets from the manufacturer and each drug has quality certificates. Buying Glucophage in our pharmacy, you save a lot of money every month. Given that diabetes care is typically lifelong, we can help you cut your medical costs significantly.

Treatment regimens and dosages

This drug can be used both in combination therapy (for example, with insulin) and as a standalone drug in the treatment of diabetes. Glucophage should always be taken during meals or immediately after meals.

The treatment regimen may depend on several factors, such as:

  • Age;
  • Therapeutic response;
  • Other medical conditions.

For adults

Before treatment, it is important to determine the right dose for you. If you have no other serious health problems and do not take other medications, you can use the following starting doses of Glucophage:

  • 500 mg;
  • 850 mg.

Starting doses are usually taken two or three times a day.

Persistence of a high blood glucose level may indicate an insufficient dosage of Glucophage and the absence of optimal therapeutic effects.

Gradual increase in the dose (by 500 mg or 850 mg in 1.5–2 week increments) and reaching a maximum dose of 3000 mg provide long-term control of diabetes.

Therapeutic response to treatment is dose-dependent and varies from patient to patient. Dose determination and adjustment should be assessed individually.

For children (the medicine is not recommended for use in children under 10 years of age)

In accordance with the recommendations, children are prescribed lower doses of Glucophage than adults are. The interval between doses of the drug may also differ.

  • The starting dosage is 500 mg twice a day.
  • After a week and each subsequent week of treatment, the dose should be increased by 500 mg.
  • Considering the effect of treatment and other medical conditions, the dose is usually increased to a maximum of 2000 mg per day.

Usually the therapeutic effect of Glucophage is noticeable after a couple of weeks. So, at first you will not see a big difference in reducing the symptoms of diabetes. Continue taking the pills during this time. If you are worried about whether the drug is helping, visit your doctor, but do not stop treatment.

Recommendations for use

You can take Glucophage tablets at any time of the day, preferably during meals or just after meals. It is recommended to choose a constant intake time. This way the drug will work better and there will be less chance that you will forget to take it.

Glucophage film-coated tablets are taken whole with a glass of water. Do not break or chew them. If a treatment is prescribed for a child, make sure he or she swallows the tablet immediately without chewing it.

General recommendations:

  • If you take one dose per day, take it in the morning (breakfast);
  • If you divide the dose in two parts, take them in the morning (breakfast) and in the evening (dinner);
  • If you divide the dose in three parts, take them in the morning (breakfast), at midday (lunch) and in the evening (dinner);
  • It would be better to divide the doses of 2000 mg and higher in 3 parts;
  • If you have the impression that the effect of the medicine is too strong or too weak, talk to your doctor or pharmacist.

Unless recommended by your doctor, Glucophage should not be combined with other antidiabetic medications in an attempt to increase the effect.

Taking Glucophage cannot replace a healthy lifestyle. Continue to follow a diet recommended by your doctor and exercise regularly.

Make sure you always have plenty of medicine. Order Glucophage online in advance so that you do not run out of pills.

Missed Dose

Avoid taking double doses or missing doses. If you forget to take a tablet at the usual time, skip that dose and follow the standard dosing regimen unless otherwise advised by your doctor.


Although Glucophage may be highly effective for the treatment of diabetes, maximum doses and standard dosage regimens are not recommended for everyone.

Be sure to tell your doctor if:

  • You have cardiovascular diseases;
  • A surgery under anesthesia is planned;
  • Any medications are used, kidney function is impaired;
  • A contrast radiography is planned;
  • You have a deficiency of vitamin B12.

During treatment, excessive alcohol consumption increases the risk of serious complications (including lactic acidosis), especially in case of malnutrition.

Use of Glucophage during pregnancy

During pregnancy, insulin is usually prescribed to keep blood glucose levels as close to normal as possible.

If you are pregnant or breastfeeding and want to start or continue taking Glucophage, you should first consult your doctor.

Possible side effects

When treating type 2 diabetes, safety is a top priority. However, adverse reactions are sometimes possible.

For this reason, when using any medication, you should be familiar with the potential side effects so that you can respond appropriately, if any of them manifest. Monitor any unusual reactions that occur during treatment.

The following list contains side effects that are relatively common when using Glucophage:

  • Vomiting;
  • Nausea;
  • Fatigue;
  • Diarrhea;
  • Flatulence;
  • Digestive problems;
  • Abdominal discomfort;
  • Headache.

In rare cases, you may feel less hungry and you may find food tastes different. These problems should resolve in a few days or weeks.

Gastrointestinal adverse reactions most often occur early in therapy and are very likely to resolve spontaneously. If they are too severe or cause discomfort, you should consider dividing the total daily dose in 2–3 parts.

Metformin: interaction with other drugs

Clinically significant drug interactions involving Metformin are rare. However, Glucophage may interact with a number of medications and substances:

  • Nifedipine (used to treat certain types of angina);
  • Furosemide (a diuretic used to treat swelling);
  • Cationic drugs (organic cation transporters);
  • Glyburide (used to treat type 2 diabetes);
  • Drugs and substances increasing blood sugar.

According to clinical studies, Glucophage can interact (increase sensitivity) with insulin. Both medicines can be taken together. In case of combined treatment, the recommended dosage regimen for Glucophage usually does not change, while standard insulin doses can be reduced.

This is not an exhaustive list of possible drug interactions.


Store Glucophage at room temperature between 20°C and 25°C. Do not freeze the drug. Store it in a dark place. Do not store the medicine in the bathroom and any other places where temperature and humidity may fluctuate.

  • Siegfried Courtney

    I order Glucophage online for the third time, orders arrive on time. So far, there have been good results, pills are worth the money, I still use them.

  • Lucian Peacock

    I bought Glucophage to control blood sugar levels. Great online service, fast delivery and a good medicine, thanks.

  • Emil Dupuy

    This drug made my life better. I take 850 mg pills three time a day. Skin rashes got less frequent.

  • Lyndon Lewerenz

    The advantage of the treatment was that the blood sugar level, which was very high at the beginning of the treatment, decreased to a controlled level.

  • Cyril Trumbauer

    It irritates me when people lack elementary logic and critical thinking. Why if Glucophage causes side effects in some people, they say that no one should take this drug. My only brother has taken Glucophage for 5 years and this is not the biggest problem in his life. His blood sugar level is under control and that's the main thing. If you have side effects, reduce the dose or change the drug.

  • Regan Wayne

    The first week it was a little hard. I often had nausea and abdominal distension. I changed my diet to a lower-carb one, the side effects were gone. Now I like these pills. My blood sugar level is okay now.

  • Alphonse Baumgartner

    I use Glucophage mainly because it does not cause a sharp drop in blood sugar level and does not lead to weight gain. Previously I used other drugs, but I put on weight.

  • Lavern Ellis

    The drug works well as before. It makes me feel better. Great service. I will continue ordering Glucophage online.

  • Niklaus Arrington

    My endocrinologist, when I was first diagnosed with diabetes, said: "There are two things you can never eat again." I started to worry because I really like to eat, even though my weight is normal. And then she added that these are "poison and cookies with poison." I tell this story for all those who says they are very limited in food. For 6 months I’ve been taking Glucophage to control my blood glucose level. I follow a diet, but it doesn’t bother me.

  • Royal Samuels

    Glucophage works very well and I have excellent results without any side effects. I have NO excess weight, but I have to watch what I eat. I used to say: "I can eat almost anything I want and not get fat." Now I’m on a diet, although it is not very strict. This way it’s easier to control blood counts.

  • Delia Anderson

    My mom has diabetes, same thing happened to me in 2021. I began to take Glucophage, switched to a low-carb diet. In 2022, I lost 19 kg of weight, blood sugar level became normal. I’m just curious whether the doctors will reverse my diagnosis if I get good blood tests. Or this disease is forever?

  • Stanley Auteberry

    Thanks for your reviews. This gives me hope that I am back to the right nutrition right on time and that I did not to go too far the wrong way. My friend has excellent results when using Glucophage. I’ve been taking this medication recently. The diagnosis of type 2 diabetes has been a shock to me, but I hope for the best.

  • Tobin Everly

    I took Glucophage, and it helped to decrease my blood sugar level to 120. As for diet, I use a lot of sweeteners. I do not follow a strict diet. I have almost normal BMI. And sometimes I eat carbs, probably because it’s nice and fun.

  • Haywood Tate

    Thank you all for writing reviews here. I got a lot of information reading your reviews. My congratulations to all who had success.

  • Courteney Kauffmann

    Although I did not faint from this drug, at first, I often had a headache. About a week later I started feeling normal again and had no more headaches. My blood sugar level seems to be getting better and that’s the main thing, most of the time it’s below 130.

  • Corinne Castle

    You MUST eat before taking this drug.

  • Joyce Bernard

    After I had started using Glucophage, I began thinking that I was in good health. I have good blood sugar levels, weight is decreased, and I have a normal appetite again. The longer I take it, the better I feel. I believe this is the best diabetes drug I’ve ever used. Try it and good luck!

  • Vincent Wildgrube

    Now I have normal blood counts. Before taking Glucophage, blood sugar level was always in the range of 150 to 160. No problem with hypoglycemia. I can recommend these pills to anyone who has difficulties in lowering their sugar levels. It works great.

  • Deidra Reich

    Glucophage helped improve my diabetes. It keeps my blood sugar levels between 90 and 130. This is the first time that I have such blood sugar levels for two years. My appetite decreased, I lost 5 kg of weight in the last 2 months, and this makes me very happy. No side effects when I take the pills after meals.

  • Marcel Bellerose

    I’ve taken Glucophage for several years, it works fine. I have good blood counts when I’m disciplined in food and exercise.

  • Lovell Tate

    Recently, I was diagnosed with diabetes. Glucophage is great (glucose level is 100–110), but I expect even better results next time I do a blood test. For the last two weeks, I’ve been active in sports, and I’m very proud of it.

  • Adolphe Samuelson

    Hello everyone. I understand that Glucophage can cause side effects and not work for everyone. But for me, it is a miracle drug. My blood sugar level dropped at once and stayed low. Now it is easier for me to work full-time, and I’m not gonna quit. The drug became an indispensable element of my everyday life. I recommend it to everyone.

  • Darrell Walters

    I discovered that it was easier for me to control blood sugar level with Glucophage than with insulin. I feel better, I have more energy, it’s easier for me to go in for sports.

  • Howard Woodcock

    I have excess weight and diabetes. Some of my treatment attempts were a failure. I tried Glucophage (3 x 850 mg) about a year ago. At first, I had an upset stomach, but after a few weeks the problem resolved. Except for this, Glucophage is a great drug.

  • Barrett Adam

    I was diagnosed 12 years ago, and I had successes and failures. First time, I took Glucophage five years ago. It had some effect but it did not satisfy the doctor. Now I take Glucophage and follow my dietary advice. My blood sugar level is always good.

  • Priska Garrod

    I tried various drugs, and Glucophage is my only solution. My insurance won’t cover it, but Glucophage has no side effects. I buy it only at online pharmacies. I think it’s worth it.

  • Ethan Dennel

    I really like this drug because I can control my sugar. I grew thin a little, and I feel much better. Excellent price. Great service.

  • Deloris Peel

    My experience with Glucophage is great. I take two 500 mg tablets in the morning and two 500 mg during lunch/dinner. I go in for sports and watch what I eat. My blood count isn’t perfect, but it’s always okay.

  • Martina Suggitt

    Glucophage first caused diarrhea. I told the doctor about it. The doctor said that this drug should be taken during meals or after meals. This was in the instructions, but I didn’t pay attention to it. Now I take 1 tablet in the morning after breakfast and 1 tablet after dinner. The diarrhea that tormented me never came back.

  • Royston Brose

    Hello! I read a lot of reviews and decided to share my experience of using Glucophage. The drug caused no digestive disorders. I had no side effects. I only had reduced appetite, less desire to eat carbs, lower blood glucose levels.
