Pancreatitis may occur while you are using this medicine. Check with your doctor right away if you have a sudden and severe stomach pain, chills, constipation, nausea, vomiting, loss of appetite, fever, or lightheadedness.

This medicine may cause hypoglycemia (low blood sugar). This is more common when this medicine is taken together with certain medicines. Low blood sugar must be treated before it causes you to pass out (unconsciousness). People feel different symptoms of low blood sugar. It is important that you learn which symptoms you usually have so you can treat it quickly. Some symptoms of low blood sugar include: behavior changes that are similar to being drunk, blurred vision, cold sweats, confusion, cool, pale skin, difficulty with thinking, drowsiness, excessive hunger, a fast heartbeat, headaches that continue, nausea, shakiness, slurred speech, or unusual tiredness or weakness. Talk to your doctor about how to treat low blood sugar.

Hyperglycemia (high blood sugar) may occur if you do not take enough or skip a dose of your medicine, overeat or do not follow your meal plan, have a fever or infection, or do not exercise as much as usual. High blood sugar can be very serious and must be treated right away. It is important that you learn which symptoms you have in order to treat it quickly. Talk to your doctor about the best way to treat high blood sugar.

It is very important to carefully follow any instructions from your health care team about:

• Alcohol—Drinking alcohol may cause severe low blood sugar. Discuss this with your health care team.
• Other medicines—Do not take other medicines unless they have been discussed with your doctor. This especially includes nonprescription medicines, such as aspirin, and medicines for appetite control, asthma, colds, cough, hay fever, or sinus problems.
• 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 the changes in the dosing of their diabetes medicine that might occur with lifestyle changes, such as changes in exercise or 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 a 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 that lists all of your medicines.
