Patient Medication Information: uses, side effects, how to take - Bio-Metformin
ABOUT THIS MEDICATION
What the medication is used for:
Bio-METFORMIN (metformin hydrochloride) tablets are used to treat type 2 diabetes which cannot be controlled by proper diet, exercise and weight reduction.
What it does:
Bio-METFORMIN is used to treat type 2 diabetes. People with type 2 diabetes are not able to make enough insulin or respond normally to the insulin their bodies make. When this happens, sugar (glucose) builds up in the blood. This can lead to serious medical problems including kidney damage, amputations, and blindness. Diabetes is also closely linked to heart disease. The main goal of treating diabetes is to lower your blood sugar to a normal level.
High blood sugar can be lowered by diet and exercise, by a number of medicines taken by mouth, and by insulin shots. While you take your diabetes medicine, continue to exercise and follow the diet advised for your diabetes, by your doctor.
No matter what your recommended diabetes management plan is, studies have shown that maintaining good blood sugar control can prevent or delay complications of diabetes, such as blindness.
Bio-METFORMIN helps control your blood sugar Although the mode of action is not fully understood, it is believed to help your body respond better to the insulin it makes naturally by:
- decreasing the amount of sugar your liver makes, and
- decreasing the amount of sugar your intestines absorb.
When it should not be used:

SIDE EFFECTS AND WHAT TO DO ABOUT THEM
Common side effects of Bio-METFORMIN include:
- diarrhea
- nausea
- upset stomach
- abdominal bloating
- gas
- loss of appetite
These side effects generally go away after you take the medicine for a while. Taking your medicine with meals can help reduce these side effects.

| IMPORTANT: PLEASE READ |
happen if you do not eat enough, if you drink alcohol, or if you take other medicines to lower blood sugar.
Lactic Acidosis. In rare cases, Bio-METFORMIN can cause a serious side effect called lactic acidosis. This is caused by a buildup of lactic acid in your blood. This build-up can cause serious damage. Lactic acidosis caused by Bio-METFORMIN is rare and has occurred mostly in people whose kidneys were not working normally. Although rare, if lactic acidosis does occur, it can be fatal in up to half the people who develop it.
It is also important for your liver to be working normally when you take Bio-METFORMIN. Your liver helps remove lactic acid from your blood.
Make sure you tell your doctor before you use Bio-METFORMIN if you have kidney or liver problems.
You should also stop using Bio-METFORMIN and call your doctor right away if you have signs of lactic acidosis. Lactic acidosis is a medical emergency that must be treated in a hospital.
If your medical condition suddenly changes, stop taking Bio-METFORMIN and call your doctor right away. This may be a sign of lactic acidosis or another serious side effect.
