FAQ
Common questions about glipizide
Below you’ll find answers to a few commonly asked questions about glipizide.
What brand names are available for glipizide?
Glipizide oral tablet is only available as a generic medication. There are no brand-name versions available at this time. Glipizide extended-release* oral tablet is available as a brand-name medication called Glucotrol XL.
A generic medication is an identical copy of the active drug in a brand-name medication. (An active drug is the ingredient that makes a medication work.) Generic drugs are believed to be as effective and safe as brand-name drugs. And generic drugs typically cost less compared to brand-name drugs.
If you have more questions about this, talk with your doctor or pharmacist.
* “Extended release” means the drug is slowly released into your body over a period of time after it’s taken.
Is it safe to take glipizide with metformin?
Yes, glipizide and metformin can be taken together. There’s a combination medication called Metaglip that contains both glipizide and metformin.
Glipizide and metformin work differently to help manage type 2 diabetes. Also, each drug has its own risks. Talk with your doctor if you have questions about whether this combination of medications is right for you.
Do I need to eat right after taking glipizide?
Yes, if you’re taking glipizide oral tablet, you should eat within 30 minutes after you take a dose. Glipizide extended-release* tablets should be taken with breakfast or your first main meal of the day.
If you don’t eat after taking glipizide, your blood sugar may drop too low, which can lead to low blood sugar. You may have symptoms such as shakiness, sweating, or dizziness. In some cases, this condition can become serious and life threatening.
Only take glipizide if you plan to eat a meal. If you have more questions about this, talk with your doctor.
* “Extended release” means the drug is slowly released into your body over a period of time after it’s taken.
Can glipizide cause long-term side effects?
Yes, in some cases glipizide may cause long-term side effects. These can last for a while after you’ve stopped taking the drug. These side effects may differ based on the form of glipizide you take.
One example of a long-term side effect of glipizide is the syndrome of inappropriate antidiuretic hormone. With this condition, your brain releases excessive amounts of antidiuretic hormone, causing your body to hold more fluid than usual.
Talk with your doctor to learn more about long-term side effects and how to best manage them. Ask your doctor for more information about how long these side effects of glipizide may last.
How does glipizide work? And how long does it take to start working?
Glipizide works by helping your pancreas release more insulin. Insulin is a hormone that signals your body to move sugar from your blood into your cells. This helps lower your blood sugar level.
Glipizide oral tablet starts lowering your blood sugar within 30 minutes after you take a dose. Glipizide extended-release* oral tablet starts lowering your blood sugar within 2–3 hours after you take a dose.
If you’d like to know more about this, talk with your doctor or pharmacist.
* “Extended release” means the drug is slowly released into your body over a period of time after it’s taken.
Uses
Uses of glipizide
The Food and Drug Administration (FDA) approves prescription drugs such as glipizide for certain conditions. The approved use for glipizide is described below.
Use for lowering blood sugar
Doctors may prescribe a glipizide oral tablet or extended-release* oral tablet for treating type 2 diabetes. The drug is used for this purpose in adults. It’s usually prescribed as a long-term treatment.
With type 2 diabetes, there’s a buildup of sugar in your blood. Usually, your pancreas releases a hormone called insulin that signals your body to move sugar from your blood into your cells. But with type 2 diabetes, your body may not respond to insulin as well, or your body might not make enough insulin. This causes the sugar to stay in your bloodstream, which leads to high blood sugar levels. Glipizide helps your body release more insulin, which helps lower your blood sugar.
Both glipizide oral tablet and glipizide extended-release oral tablet are prescribed together with diet and exercise for type 2 diabetes.
Doctors may not prescribe glipizide oral tablet or glipizide extended-release oral tablet in certain situations, such as for treating type 1 diabetes or diabetic ketoacidosis.
* “Extended release” means the drug is slowly released into your body over a long period of time after it’s taken.
