What should I watch for while taking hyoscyamine?
You may get dizzy or have blurred vision. Do not drive, use machinery, or do anything that needs mental alertness until you know how hyoscyamine 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 dizzy, avoid alcoholic drinks.
Stay out of bright light and wear sunglasses if hyoscyamine makes your eyes more sensitive to light.
Your mouth may get dry. Chewing sugarless gum or sucking hard candy, and drinking plenty of water will help.
Hyoscyamine may cause dry eyes and blurred vision. If you wear contact lenses you may feel some discomfort. Lubricating drops may help. See your ophthalmologist if the problem does not go away or is severe.
Avoid extreme heat (e.g., hot tubs, saunas). Hyoscyamine can cause you to sweat less than normal. Your body temperature could increase to dangerous levels, which may lead to heat stroke.
Where can I keep my medicine?
Each dose of hyoscyamine injection will be administered in the hospital or the office of a health care professional. You will not be given hyoscyamine injection doses to store at home.
