What happens if I miss a dose?

Take the missed dose as soon as you remember. If it is almost time for your next dose, skip the missed dose and take the medicine at your next regularly scheduled time. Do not take extra medicine to make up the missed dose.

What happens if I overdose?

Seek emergency medical attention if you think you have used too much of this medicine.

Overdose symptoms may include headache, dizziness, dry mouth, trouble swallowing, nausea, vomiting, blurred vision, hot dry skin, and feeling restless or nervous.

What should I avoid while taking hyoscyamine?

Avoid taking antacids at the same time you take hyoscyamine. Antacids can make it harder for your body to absorb hyoscyamine. If you use an antacid, take it after you have taken hyoscyamine and eaten a meal.

Hyoscyamine can cause side effects that may impair your vision, thinking, or reactions. Be careful if you drive or do anything that requires you to be awake and able to see clearly.

Avoid drinking alcohol. It can increase drowsiness and dizziness while you are taking hyoscyamine.

Avoid becoming overheated or dehydrated during exercise and in hot weather. Because hyoscyamine reduces sweating, it can increase your risk of heat stroke.

• amantadine (Symmetrel);

This list is not complete and there may be other drugs that can interact with hyoscyamine. Tell your doctor about all the prescription and over-the-counter medications you use.
