Common questions about pioglitazone/glimepiride
Below you’ll find answers to a few commonly asked questions about pioglitazone/glimepiride.
Can I take pioglitazone/glimepiride with metformin?
Yes, it’s generally considered safe to take pioglitazone/glimepiride with metformin (Fortamet, Glumetza). These medications aren’t known to interact with each other.
That said, metformin and pioglitazone/glimepiride can cause some similar side effects. Examples include low blood sugar and, in rare cases, liver failure. Taking these medications together increases your risk of these side effects. But the benefits of taking the drugs to lower blood sugar may outweigh the risks for some people.
Your doctor or pharmacist can provide more information on the benefits and risks of taking metformin with pioglitazone/glimepiride. They can also determine whether this is a safe combination for you to take.
Is pioglitazone/glimepiride similar to glipizide, glyburide, or vildagliptin?
Yes, in some ways. But these drugs also have some differences.
Pioglitazone/glimepiride, glipizide (Glucotrol XL), glyburide (Glynase), and vildagliptin are all prescribed to manage blood sugar levels in people with type 2 diabetes.
Unlike the other drugs mentioned here, vildagliptin is not approved by the Food and Drug Administration (FDA) for use in the United States.
Glimepiride, glipizide, and glyburide all belong to a group of drugs called sulfonylureas. This means these drugs work in the same way to lower blood sugar levels. Pioglitazone and vildagliptin work differently to treat type 2 diabetes.
Your doctor or pharmacist can provide more information on how pioglitazone/glimepiride compares to other treatments for type 2 diabetes.
Will pioglitazone/glimepiride 30 mg/2 mg cause fewer side effects than the 30 mg/4 mg strength of the drug?
Maybe. In general, lower strengths of a drug are less likely to cause side effects compared with higher strengths. This was true for certain side effects reported in pioglitazone/glimepiride’s studies, such as weight gain and edema.
If you’d like to know more about how your pioglitazone/glimepiride dose affects your risk of side effects, talk with your doctor or pharmacist.
Does pioglitazone/glimepiride cause long-term side effects?
Yes, in some cases, pioglitazone/glimepiride may cause long-term side effects. These can occur if you take the drug for a long time. And some side effects may last for a while after you’ve stopped taking the drug.
Examples of long-term side effects include:
- diabetic macular edema (an eye condition that may result from diabetes)
- liver failure, which may not go away even if you stop treatment
- boxed warning: risk of heart failure*
* For details about this side effect, see the “Interactions and warnings for pioglitazone/glimepiride” section below.
Talk with your doctor to learn more about these side effects and how to best manage them. Ask your doctor for more information about how long these side effects of pioglitazone/glimepiride may last.
How does pioglitazone/glimepiride work? And how long does it take to start working?
Pioglitazone/glimepiride contains two active drugs. An active drug is the ingredient that makes a medication work.
Pioglitazone and glimepiride work differently for managing blood sugar levels in people with type 2 diabetes.
Pioglitazone belongs to a group of drugs called thiazolidinediones. It can lower blood sugar levels by helping the insulin made by your body work better. Insulin is a hormone that helps send sugar out of your blood and into your cells to use as energy.
Glimepiride belongs to a group of drugs called sulfonylureas. It helps lower blood sugar levels by causing your pancreas to release insulin.
Pioglitazone/glimepiride begins working when you take a dose. But it can take a few weeks or months before you notice long-term changes to your blood sugar level. Your doctor can provide more information on how they’ll determine whether the drug helps manage your blood sugar.
If you have additional questions about how pioglitazone/glimepiride works or when you may notice changes in your blood sugar level from taking the drug, ask your doctor or pharmacist.
Uses of pioglitazone/glimepiride
The Food and Drug Administration (FDA) approves prescription drugs such as pioglitazone/glimepiride for certain conditions. Approved uses for pioglitazone/glimepiride are described below.
Use for type 2 diabetes
Doctors may prescribe pioglitazone/glimepiride oral tablet for managing blood sugar levels in adults with type 2 diabetes. For this purpose, the drug is part of a treatment plan that includes a balanced diet and exercise. It’s typically prescribed as a long-term treatment.
Usually, a person’s body releases the hormone insulin to move glucose (sugar) out of the blood and into cells. The cells use this sugar for energy. With type 2 diabetes, cells stop responding or don’t respond as well to insulin. And the body may stop making insulin or may not make enough. This causes high blood sugar.
Over time, high blood sugar can cause serious harm to the heart, kidneys, eyes, and other parts of the body.
Symptoms of type 2 diabetes include fatigue (low energy), increased thirst or appetite, and urinating more frequently than usual.
Doctors will likely not prescribe pioglitazone/glimepiride oral tablet to treat type 1 diabetes. Also, pioglitazone/glimepiride should not be used to treat diabetic ketoacidosis (DKA), a serious condition that causes the blood to be too acidic.
Dosage of pioglitazone/glimepiride
The dosage of pioglitazone/glimepiride your doctor prescribes may vary based on your condition and certain other factors. Talk with your doctor about the dosage you should take.

You should not take more pioglitazone/glimepiride than your doctor prescribes. For some drugs, doing so may lead to serious side effects or overdose.
