Overview

Amaryl is a prescription medication used to treat type 2 diabetes. This medication belongs to a group of drugs called sulfonylureas, which help to lower blood sugar by causing the pancreas to produce insulin (a natural substance that is needed to break down sugar in the body). It also helps the body use insulin efficiently.

Amaryl comes in tablet form. It is usually taken once daily with breakfast.

Common side effects include headache, weakness, and nausea. Amaryl can cause dizziness. Do not drive or operate heavy machinery until you know how it affects you.

  • Amaryl can decrease the number of red blood cells in people with glucose-6-phosphate dehydrogenase (G6PD) deficiency.  Alert your doctor if you have a history of G6PD deficiency or anemia.
  • Increased risk of cardiovascular mortality with Sulfonylureas. The administration of oral hypoglycemic drugs has been reported to be associated with increased cardiovascular mortality as compared to treatment with diet alone or diet plus insulin. Ask your doctor about the risks and benefits of taking Amaryl.

Ask your doctor about the safe use of alcoholic beverages while you are taking Amaryl. Alcohol can make the side effects from Amaryl worse. Consuming alcohol while taking Amaryl also may cause symptoms such as flushing (reddening of the face), headache, nausea, vomiting, chest pain, weakness, blurred vision, mental confusion, sweating, choking, breathing difficulty, and anxiety.

Avoid unnecessary or prolonged exposure to sunlight, and wear protective clothing, sunglasses, and sunscreen. Amaryl may make your skin sensitive to sunlight.

Ask your doctor what to do if you get sick, develop an infection or fever, experience unusual stress, or are injured. These conditions can affect your blood sugar and the amount of Amaryl you may need.

Do not take Amaryl if you:

  • are allergic to Amaryl or to any of its ingredients

Pregnancy

Tell your doctor if you are pregnant or plan to become pregnant.

The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.

Amaryl falls into category C. There are no well-controlled studies that have been done in pregnant women. Amaryl should be used during pregnancy only if the possible benefit outweighs the possible risk to the unborn baby.

Breastfeeding

Tell your doctor if you are breastfeeding or plan to breastfeed.

It is not known if Amaryl crosses into human milk. Because many medications can cross into human milk and because of the possibility for serious adverse reactions in nursing infants with use of this medication, a choice should be made whether to stop nursing or stop the use of this medication. Your doctor and you will decide if the benefits outweigh the risk of using Amaryl.

Quick facts

Avoid unnecessary or prolonged exposure to sunlight, and wear protective clothing, sunglasses, and sunscreen. Glimepiride may make your skin sensitive to sunlight.

Glimepiride can cause low blood sugar levels (hypoglycemia) in patients. Make sure you know the signs and symptoms of low blood sugar.

Alcohol can intensify the side effects of glimepiride.

Glimepiride should be taken with a healthy diet to maximize its blood glucose lowering effects.

After exposure to stress, such as fever, trauma, infection, or surgery, glimepiride may cause you to lose control over your blood glucose levels.
