Proper Use of This Medicine

Use this medicine only as directed even if you feel well and do not notice any signs of high blood sugar. Do not take more of this medicine and do not take it more often than your doctor ordered . To do so may increase the chance of serious side effects. Remember that this medicine will not cure your diabetes but it does help control it. Therefore, you must continue to take it as directed if you expect to lower your blood sugar and keep it low. You may have to take an antidiabetic medicine for the rest of your life . If high blood sugar is not treated, it can cause serious problems, such as heart failure, blood vessel disease, eye disease, or kidney disease.

Your doctor will give you instructions about diet, exercise, how to test your blood sugar levels, and how to adjust your dose when you are sick.

  • Diet - The daily number of calories in the meal plan should be adjusted by your doctor or a registered dietitian to help you reach and maintain a healthy body weight. In addition, regular meals and snacks are arranged to meet the energy needs of your body at different times of the day. It is very important that you follow your meal plan carefully .
  • Exercise - Ask your doctor what kind of exercise to do, the best time to do it, and how much you should do each day.
  • Blood tests - This is the best way to tell whether your diabetes is being controlled properly. Blood sugar testing helps you and your health care team adjust the dose of your medicine, meal plan, or exercise schedule.
  • On sick days - When you become sick with a cold, fever, or the flu, you need to take your usual dose of sulfonylurea, even if you feel too ill to eat. This is especially true if you have nausea, vomiting, or diarrhea. Infection usually increases your need to produce more insulin. Sometimes you may need to be switched from your sulfonylurea to insulin for a short period of time while you are sick to properly control blood sugar. Call your doctor for specific instructions.
    Continue taking your sulfonylurea and try to stay on your regular meal plan. If you have trouble eating solid food, drink fruit juices, nondiet soft drinks, or clear soups, or eat small amounts of bland foods. A dietitian or your health care professional can give you a list of foods and the amounts to use for sick days.
    Test your blood sugar level at least every 4 hours while you are awake and check your urine for ketones. If ketones are present, call your doctor at once. If you have severe or prolonged vomiting, check with your doctor. Even when you start feeling better, let your doctor know how you are doing.
