Tell your prescriber or health care professional about all other medicines you are taking, including non-prescription medicines, nutritional supplements, or herbal products. Also tell your prescriber or health care professional if you are a frequent user of drinks with caffeine or alcohol, if you smoke, or if you use illegal drugs. These may affect the way your medicine works. Check with your health care professional before stopping or starting any of your medicines.
What should I watch for while taking metformin?
Visit your prescriber or health care professional for regular checks on your progress. Your prescriber will check your blood sugar, kidney function, and other tests from time to time.
Learn how to monitor your blood sugar. Learn what to do if you have high or low blood sugar. Do not skip meals. If you are exercising much more than usual you may need extra snacks to avoid side effects caused by low blood sugar. Do not change your medication dose without talking to your prescriber.
If you have mild symptoms of low blood sugar, eat or drink something containing sugar at once and contact your health care professional. It is wise to check your blood sugar to confirm that it is low. It is important to recognize your own symptoms of low blood sugar so that you can treat them quickly. Make sure family members know that you can choke if you eat or drink when you develop serious symptoms of low blood sugar, such as seizures or unconsciousness. They must get medical help at once.
If you develop a severe diarrhea or vomiting, or are unable to maintain proper fluid intake, you should contact your prescriber. "Sick-days" may require adjustments to your dosage or your illness may need to be evaluated. Ask your prescriber what you should do if you become ill.
If you are going to have surgery or will need an x-ray procedure that uses contrast agents, tell your prescriber or health care professional that you are taking this medicine.
Wear a medical identification bracelet or chain to say you have diabetes, and carry a card that lists all your medications.
