Precautions

It is very important that your doctor check your progress at regular visits to see if the medicine is working properly and to check for unwanted effects.

This medicine may cause a serious allergic reaction, called angioedema, which can be life-threatening and requires immediate medical attention. Tell your doctor right away if you have a large, hive-like swelling on the face, eyelids, lips, tongue, throat, hands, legs, feet, or sex organs after using this medicine.

This medicine may increase your risk of having urinary retention (trouble passing urine or not fully emptying the bladder). Check with your doctor if you have a decrease in urine volume, decrease in the frequency of urination, difficulty in passing urine (dribbling), or painful urination.

This medicine may make you sweat less, causing your body temperature to increase. Use extra care not to become overheated during exercise or hot weather while you are taking this medicine, since overheating may result in heat stroke.

Avoid drinking alcohol while you are taking this medicine.

This medicine may cause some people to become dizzy, drowsy, or have blurred vision. Do not drive or do anything else that could be dangerous until you know how this medicine affects you.

This medicine may cause dryness of the mouth, nose, and throat. For temporary relief of mouth dryness, use sugarless candy or gum, melt bits of ice in your mouth, or use a saliva substitute. However, if your mouth continues to feel dry for more than 2 weeks, check with your medical doctor or dentist. Continuing dryness of the mouth may increase the chance of dental disease, including tooth decay, gum disease, and fungus infections.

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.
