Warnings
You should not take Toviaz if you have uncontrolled narrow-angle glaucoma, or if you have a blockage of the urinary tract, stomach, or intestines.
Do not crush, chew, or break a Toviaz extended-release tablet. Swallow it whole. Breaking or opening the pill may cause too much of the drug to be released at one time. Toviaz may cause blurred vision or impair your thinking or reactions. Be careful if you drive or do anything that requires you to be alert and able to see clearly.
Avoid becoming overheated or dehydrated during exercise and in hot weather. Toviaz can decrease perspiration and you may be more prone to heat stroke.
