Glucophage Metformin Hydrochloride 850mg 50 Tablets

 is the generic name of the prescription medications Glucophage, Glumetza, and Fortamet, used to control blood sugar in people with type 2 diabetes.

  • Type 2 diabetes is a disease that occurs when the body does not produce or use insulin normally, which results in high blood sugar (glucose).
  • Metformin works by decreasing the amount of sugar you absorb from food and reducing the amount of glucose your liver makes. It also increases your body's response to insulin.
  • Metformin is in a class of medications called biguanides. It's sometimes used along with diet, exercise, and other medications to control blood glucose levels.
  • It's also used to prevent the development of diabetes in people at high risk for the disease, treat polycystic ovary syndrome (PCOS), and control weight gain that occurs from taking certain drugs.
  • The Food and Drug Administration (FDA) approved the medication in 1994.

Metformin and PCOS (Polycystic Ovary Syndrome)

Polycystic ovary syndrome (PCOS) is a common endocrine disorder that affects about one in 10 women of reproductive age.

Women with PCOS may have enlarged ovaries containing fluid, or follicles. These fluids may cause infrequent or prolonged menstrual periods, excess hair growth, acne, and weight gain.

The exact cause of PCOS is unknown, but the disorder has been linked to insulin resistance and excess insulin in the body.

If you have insulin resistance, your body cannot use insulin effectively. As a result, your pancreas has to secrete more insulin to make glucose available to cells and tissues, including those that compose the ovaries.

Researchers believe excess insulin may affect the ovaries by increasing androgen production, which may interfere with the ovaries' ability to ovulate.

Because metformin can increase your body’s response to insulin, the drug has been used in the treatment of PCOS, particularly in women with gestational diabetes.

There is conflicting data surrounding the efficacy of metformin in PCOS.

Studies have reported that metformin can restore ovulation, reduce weight, reduce circulating androgen levels, reduce the risk of miscarriage, and reduce the risk of gestational diabetes mellitus in women with PCOS.

It’s also been reported that metformin improves pregnancy outcome, as an adjunct to ovarian stimulation in women undergoing in vitro fertilization (IVF).

However, there are other studies indicating that metformin is not effective in improving insulin response in women with PCOS.

Oral contraceptives are the first-choice therapy in most non-diabetic patients in PCOS. Oral contraceptives are preferred over metformin for endometrial protection, hyperandrogenic symptoms, and restoration of normal menstrual cycles.

If you have been diagnosed with PCOS, talk to your doctor to see if metformin is an option.


In rare cases, metformin may cause a life-threatening condition known as lactic acidosis (a build-up of lactic acid in the body). You may be more likely to develop this condition if you:

  • Have liver or kidney disease
  • Have congestive heart failure
  • Have a severe infection
  • Drink large amounts of alcohol
  • Are dehydrated
  • You should tell your doctor if you are over 80 years old and if you have ever suffered a heart attack, stroke, diabetic ketoacidosis (an extremely high blood sugar episode that requires emergency medical treatment) or coma, or kidney, heart, or liver disease.

You should also tell your doctor you are taking metformin before having any type of surgery, including dental procedures. If you are having any type of X-ray where dye is injected, you may need to stop taking metformin. Your doctor will advise you on when to stop and restart the drug.

Some laboratory animals that were given high doses of metformin developed non-cancerous abnormal growths of tissue (polyps) on the uterus. It is not known if this medicine increases the risk of polyps in humans. You can talk to your doctor about this risk.

You should keep all appointments with your doctor while taking metformin. Your physician will likely order specific tests to check your body's response to the drug.

This medicine controls diabetes but doesn't cure it. You should continue to take metformin even if you feel well. Don't stop taking the drug without talking to your physician.

Metformin shouldn't be used to treat people with type 1 diabetes. The medication should not be given to a child younger than 10 years old. The extended-release form of the drug should not be given to a child younger than 17 years old.

Metformin and Weight Loss

Some patients may experience weight loss when starting metformin. The drug can cause a loss of appetite and feelings of fullness that lead to this effect.

Metformin and PCOS

Metformin is sometimes used to lower insulin and blood sugar levels in women with polycystic ovary syndrome, or PCOS. PCOS causes irregular or no menstrual periods, irregular ovulation, and high levels of androgens (male hormones) in the body, sometimes leading to hirsutism (excessive growth of facial or body hair on women)

Lowering blood sugar and insulin may help regulate menstrual cycles, start ovulation, and lower the risk of miscarriage in women with PCOS.

Metformin and Fertility

Regulating blood sugar with metformin may help women who struggle with infertility.

Pregnancy and Metformin

Metformin is an FDA Pregnancy Category B drug, which means it is not expected to be harmful to an unborn baby. However, you should talk to your doctor before taking this medicine if you are pregnant or plan to become pregnant.

It's not known whether metformin passes into breast milk and could harm a nursing infant. You should also talk to your doctor before starting to breastfeed if you are taking metformin.
