Hypoglycemia
Glipizide oral tablets are used to manage blood sugar levels in adults with type 2 diabetes. But in some cases, glipizide may cause your blood sugar to drop too low. This causes hypoglycemia (low blood sugar).
The American Diabetes Association defines hypoglycemia as a blood sugar level of 70 milligrams per deciliter (mg/dL) or lower.
In clinical studies of glipizide oral tablets, low blood sugar was more common in people with certain risk factors or in certain situations. These may include:
- older age (65 years and older)
- kidney, liver, or adrenal gland problems
- use of insulin or other drugs that lower blood sugar
- use of alcohol
- frequently skipping meals or not eating regularly
- participation in intense or prolonged exercise
To find out how often hypoglycemia occurred in clinical studies, see prescribing information on glipizide IR oral tablets and glipizide ER oral tablets.
You may notice certain symptoms when your blood sugar first begins to drop too low. These may include feeling nervous or anxious, shaking, sweating, or feeling clammy.
If your blood sugar continues to drop, severe hypoglycemia (very low blood sugar) may occur. This is a medical emergency and requires urgent treatment. If not treated quickly, it can cause the following:
To prevent low blood sugar from becoming severe, it is important to recognize the early symptoms listed above. Before starting glipizide, you and your doctor will come up with a hypoglycemia action plan. The plan will include what you should do at the first sign of low blood sugar.
Some people may not notice the early symptoms of low blood sugar due to having other medical conditions or taking certain medications, such as beta-blockers. In this case, your doctor may recommend a different medication or prescribe a lower dose of glipizide for you. They may also suggest checking your blood sugar more often.
Before taking glipizide, talk with your doctor about your risk for low blood sugar during your treatment. It's also important to talk with them about your health history and the medications you take.
Cardiovascular problems
In 1970, a University Group Diabetes Program (UGDP) research study showed that taking certain diabetes drugs long term may increase the risk of death due to cardiovascular (heart- or blood vessel-related) problems. However, a more recent
Because of this risk, it's important to talk with your doctor about your heart health before starting glipizide. Your doctor may look at whether you have risk factors for cardiovascular disease, such as:
The American Diabetes Association also recommends drugs other than sulfonylureas as the first treatment option for people with cardiovascular disease. So if you have cardiovascular disease, your doctor can help determine whether another treatment option is better for you.
Gastrointestinal problems
Gastrointestinal (digestive system) problems are common side effects of glipizide. These may include side effects such as:
These gastrointestinal side effects tend to improve on their own within the first few days or weeks of treatment.
However, if these side effects don't go away, or if they bother you or become severe, talk with your doctor. They may suggest ways to relieve these side effects, or they may adjust your dosage of glipizide.
Allergic reactionAs with most drugs, some people can have an allergic reaction after taking glipizide oral tablets. Allergic skin reactions, sometimes temporary, were reported in clinical studies of the drug.
Symptoms of a mild allergic reaction can include:
A more severe allergic reaction is rare but possible. Symptoms of a severe allergic reaction can include:
- swelling under your skin, typically in your eyelids, lips, hands, or feet
- swelling of your tongue, mouth, or throat
- trouble breathing

Call your doctor right away if you have an allergic reaction to glipizide oral tablets, as the reaction could become severe. Call 911 or your local emergency number if your symptoms feel life threatening or if you think you're having a medical emergency.
