What should I watch for?
You may get drowsy, dizzy, or have blurred vision. Do not drive, use machinery, or do anything that needs mental alertness until you know how this medicine affects you. To reduce the risk of dizzy or fainting spells, do not sit or stand up quickly, especially if you are an older patient. Alcohol can make you more drowsy. Avoid alcoholic drinks.
Avoid extreme heat (e.g., hot tubs, saunas). This medicine can cause you to sweat less than normal. Your body temperature could increase to dangerous levels, which may lead to heat stroke.
Your mouth may get dry. Chewing sugarless gum or sucking hard candy, and drinking plenty of water may help. Contact your doctor if the problem does not go away or is severe.
