This medicine may cause dizziness, lightheadedness, or fainting. Make sure you know how you react to this medicine before you drive, use machines, or do anything else that could be dangerous if you are dizzy or not alert.
Dizziness, lightheadedness, or fainting may occur, especially when you get up from a lying or sitting position suddenly. These symptoms are more likely to occur when you begin taking this medicine, or when the dose is increased. Sitting or lying down may help alleviate these unwanted effects.
Before having any kind of surgery (including dental surgery or cataract surgery) or emergency treatment, tell the medical doctor or dentist in charge that you are taking this medicine. A serious eye problem called Intraoperative Floppy Iris Syndrome (IFIS) has occurred in some patients who were taking this medicine or who had recently taken this medicine when they had cataract surgery.
For diabetic patients:
-
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 worsen the symptoms of heart failure in some patients.

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 completely. Some conditions may become worse when the medicine is stopped suddenly, which can be dangerous.
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.
