Drug Information
Metformin hydrochloride is a biguanide, a class of diabetes medications in clinical use for over 60 years. The extended-release (ER) version was introduced in 2000 under the brand name Glucophage XR. The original brand-name products have been discontinued, but generic metformin ER remains widely available.
What Metformin ER Treats
Metformin ER is an add-on to diet and exercise to improve blood sugar control in adults with type 2 diabetes. It is the first-line medication recommended by the American Diabetes Association for most people diagnosed with type 2 diabetes.
Metformin is not approved for type 1 diabetes. It does not cause the body to produce insulin and is not a substitute for insulin in patients who need it.
How Metformin ER Works
Metformin lowers blood sugar primarily by reducing the glucose your liver releases between meals and overnight. It also slows glucose absorption in the intestines and improves how muscle and fat cells respond to insulin.
Unlike sulfonylureas or insulin, metformin rarely causes low blood sugar (hypoglycemia) when used alone. It is weight-neutral or may cause modest weight loss, which is why doctors often choose it first for type 2 diabetes.
The “ER” in Metformin ER stands for extended-release. The tablet dissolves slowly, releasing the drug over several hours. You take it once daily instead of two or three times, and it is easier on the stomach. In clinical studies, about 90% of patients who could not tolerate standard metformin stayed on the extended-release version.
Metformin ER Dosage
The usual starting dose is 500mg once daily with the evening meal. Your doctor may increase the dose by 500mg per week, up to 2000mg once daily. PandaMeds carries the 1000mg tablet, the most commonly prescribed maintenance dose.
Swallow the tablet whole with food. Do not crush, chew, or split it. This would break the extended-release mechanism and release the full dose at once. A soft tablet shell may appear in your stool, which is normal. If you miss a dose, take it with your next meal. Do not double up.

Important safety information
Metformin carries a boxed warning for lactic acidosis. This condition is rare but can be fatal. The risk increases with kidney impairment, liver disease, excessive alcohol use, dehydration, or heart failure. Symptoms include:
- Muscle pain
- Weakness
- Difficulty breathing
- Unusual drowsiness
- Feeling cold.
Stop taking metformin and get emergency medical care if these occur.
Your doctor should check kidney function before starting metformin and at least once a year afterward. Stop metformin temporarily before any surgery or imaging procedure using iodinated contrast dye.
Common side effects
- Diarrhea
- Nausea
- Stomach pain and gas.
These usually go away within a few weeks. Taking metformin ER with food and starting at a low dose helps reduce stomach issues. Long-term use may lower vitamin B12 levels, so your doctor should check B12 periodically.

Frequently Asked Questions
What is the difference between Metformin and Metformin ER?
Standard metformin (immediate-release) is taken two or three times a day. Metformin ER dissolves slowly and is taken once daily, usually with dinner. The ER version causes fewer GI side effects. Both control blood sugar equally well.
Does Metformin cause weight gain?
No. Metformin is weight-neutral or causes modest weight loss in many patients. It does not stimulate insulin production, which is why it does not cause the weight gain associated with some other diabetes drugs.
Can I drink alcohol while taking Metformin?
Heavy or binge drinking raises the risk of lactic acidosis and should be avoided. Occasional, moderate alcohol use is generally acceptable, but discuss your habits with your doctor. Alcohol can also lower blood sugar, which may interact with your diabetes management plan.
Why order from Canada if generic Metformin is cheap in the US?
US generic metformin ER is inexpensive at many pharmacies with a coupon, but prices vary by pharmacy and location. PandaMeds provides a fixed, upfront price with no insurance paperwork, no prior authorizations and direct-to-door shipping for patients who prefer that convenience.
