PART III: CONSUMER INFORMATION
ECL-METFORMIN Metformin Hydrochloride Tablets, USP
This leaflet is part III of a three-part "Product Monograph" published when ECL-METFORMIN was approved for sale in Canada and is designed specifically for Consumers. This leaflet is a summary and will not tell you everything about ECL-METFORMIN. Contact your doctor or pharmacist if you have any questions about the drug.
What this medication is used for:
ECL-METFORMIN (metformin hydrochloride) is used to treat type 2 diabetes which cannot be controlled by proper diet, exercise and weight reduction.
What it does:
ECL-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.
ECL-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:
Do not take ECL-METFORMIN if you:
have unstable and/or insulin-dependent (Type I) diabetes mellitus

SIDE EFFECTS AND WHAT TO DO ABOUT THEM
| IMPORTANT: PLEASE READ |
If you have taken too much ECL-METFORMIN, immediately see your doctor, contact the poison control or go to the nearest hospital emergency department. Do this even if there are no signs of discomfort or poisoning.
Missed Dose:
If you forget to take ECL-METFORMIN tablets, do not take a double dose to make up for the forgotten individual doses. Take the next dose at the usual time.

- diarrhea
- nausea
- vomiting
- abdominal-bloating
- gas

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. Tell your doctor if the side effects bother you a lot, last for more than a few weeks, come back after they’ve gone away, or start later in therapy. You may need a lower dose or a need to stop taking the medicine for a short period or for good.
ECL-Metformin hydrochloride rarely cause hypoglycemia (low blood sugar) by themselves. However, hypoglycemia can 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, metformin hydrochloride 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 cause by metformin hydrochloride 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 ECL-METFORMIN. Your liver helps remove lactic acid from your blood.
Make sure you tell your doctor before you use ECL-
METFORMIN if you have kidney or liver problems.
You should also stop using ECL-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 ECL-METFORMIN and call your doctor right away. This may be a sign of lactic acidosis or another serious side effect.
