Uses for glimepiride
Glimepiride is used to treat high blood sugar levels caused by type 2 diabetes. It may be used alone, or in combination with insulin or another oral medicine such as metformin. In type 2 diabetes, insulin produced by the pancreas is not able to get sugar into the cells of the body where it can work properly. Using glimepiride will help lower blood sugar when it is too high and help restore the way you use food to make energy. . Some people can control type 2 diabetes with diet alone or diet and exercise. Following a specially planned diet and exercising will always be important when you have diabetes, even when you are taking medicines. To work properly, the amount of glimepiride you take must be balanced against the amount and type of food you eat and the amount of exercise you do. If you change your diet, your exercise, or both, you will want to test your blood sugar to find out if it is too low. Your doctor will teach you what to do if this happens.
Glimepiride is available only with your doctor's prescription.
Before using glimepiride
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For glimepiride, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to glimepiride or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Appropriate studies have not been performed on the relationship of age to the effects of glimepiride in the pediatric population. Safety and efficacy have not been established.
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of glimepiride in the elderly. However, elderly patients are more likely to have low blood sugar and age-related kidney problems, which may require caution and an adjustment in the dose for patients receiving glimepiride.
There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.

Precautions while using glimepiride
It is very important that your doctor check your progress at regular visits to make sure that glimepiride is working properly. Blood and urine tests may be needed to check for unwanted effects.
It is very important to follow carefully any instructions from your health care team about:
- Alcohol—Drinking alcohol may cause severe low blood sugar. Discuss this with your health care team.
- Counseling—Other family members need to learn how to prevent side effects or help with side effects if they occur. Also, patients with diabetes may need special counseling about diabetes medicine dosing changes that might occur because of lifestyle changes, such as changes in exercise and diet. Furthermore, counseling on contraception and pregnancy may be needed because of the problems that can occur in patients with diabetes during pregnancy.
- Travel—Keep your recent prescription and your medical history with you. Be prepared for an emergency as you would normally. Make allowances for changing time zones and keep your meal times as close as possible to your usual meal times.
- In case of emergency—There may be a time when you need emergency help for a problem caused by your diabetes. You need to be prepared for these emergencies. It is a good idea to wear a medical identification (ID) bracelet or neck chain at all times. Also, carry an ID card in your wallet or purse that says you have diabetes and a list of all of your medicines.
Check with your doctor right away if you start having chest pain or discomfort; nausea; pain or discomfort in the arms, jaw, back, or neck; shortness of breath; sweating; or vomiting while you are using glimepiride. These may be symptoms of a serious heart problem, including a heart attack.
Too much glimepiride can cause low blood sugar (hypoglycemia) when it is used under certain conditions. Symptoms of low blood sugar must be treated before they lead to unconsciousness (passing out). Different people may feel different symptoms of low blood sugar. It is important that you learn which symptoms of low blood sugar you usually have so that you can treat it quickly and call someone on your health care team right away when you need advice.
Symptoms of low blood sugar include anxiety; behavior change similar to being drunk; blurred vision; cold sweats; confusion; cool, pale skin; difficulty in thinking; drowsiness; excessive hunger; fast heartbeat; headache (continuing); nausea; nervousness; nightmares; restless sleep; shakiness; slurred speech; or unusual tiredness or weakness.
If symptoms of low blood sugar occur, eat glucose tablets or gel, corn syrup, honey, or sugar cubes; or drink fruit juice, non-diet soft drink, or sugar dissolved in water. Also, check your blood for low blood sugar. Glucagon is used in emergency situations when severe symptoms such as seizures (convulsions) or unconsciousness occur. Have a glucagon kit available, along with a syringe or needle, and know how to use it. Members of your household also should know how to use it.
Glimepiride may cause dizziness, drowsiness, or less alert than they are normally. Make sure you know how you react to glimepiride before you drive, use machines, or do other jobs that require you to be alert or able to think well.
Glimepiride may cause serious types of allergic reactions, including anaphylaxis. These conditions may be life-threatening and require immediate medical attention. Stop using glimepiride and check with your doctor right away if you have a blistering, peeling, or red skin rash; itching; a large, hive-like swelling on the face, eyelids, lips, tongue, throat, hands, legs, feet, or sex organs; trouble with breathing; or chest tightness while you are using glimepiride.
Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
