This medicine may cause changes in blood sugar levels. Also, this medicine may cover up the symptoms of low blood sugar, including fast heartbeat and increase the risk for serious or prolonged hypoglycemia (low blood sugar). Check with your doctor if you notice a change in your normal symptoms or a change in the results of your blood or urine sugar tests. Call your doctor right away if you have anxiety, blurred vision, chills, cold sweats, coma, confusion, cool, pale skin, depression, dizziness, fast heartbeat, headache, increased hunger, nausea, nervousness, nightmares, seizures, shakiness, slurred speech, or unusual tiredness or weakness.

This medicine may increase your risk of getting skin cancer (eg, non-melanoma skin cancer). Avoid sun exposure. Use a sunscreen when you are outdoors. Avoid sunlamps and tanning beds. Talk to your doctor if you have concerns about this risk.

Make sure any doctor or dentist who treats you knows that you are using this medicine. Do not stop taking this medicine before surgery without your doctor's approval.

This medicine may cause some people to become less alert than they are normally. If this side effect occurs, do not drive, use machines, or do anything else that could be dangerous if you are not alert while taking this medicine.

Do not interrupt or stop taking this medicine without first checking with your doctor. Your doctor may want you to gradually reduce the amount you are taking before stopping it completely. Some conditions may become worse when the medicine is stopped suddenly, which can be dangerous.

Check with your doctor right away if you start having dry mouth, increased thirst, muscle cramps, nausea or vomiting, unusual tiredness or weakness, severe drowsiness or dizziness, seizures, a decrease in urine, or a fast heartbeat while you are using this medicine. These may be symptoms of dehydration or mineral imbalance.

Check with your doctor immediately if blurred vision, difficulty in reading, eye pain, or any other change in vision occurs during or after treatment. This could be a sign of a serious eye problem. Your doctor will want you to have your eyes checked by an ophthalmologist (eye doctor).
