What happens if I miss a dose?
Take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.
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 may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be alert.
Drinking alcohol can increase drowsiness and dizziness while you are taking hyoscyamine.
Avoid becoming overheated or dehydrated during exercise and in hot weather. Hyoscyamine can decrease sweating and you may be more prone to heat stroke.

Tell your doctor about all other medicines you use, especially:
- amantadine (Symmetrel);
- haloperidol (Haldol);
- an MAO inhibitor such as furazolidone (Furoxone), isocarboxazid (Marplan), phenelzine (Nardil), rasagiline (Azilect), selegiline (Eldepryl, Emsam), or tranylcypromine (Parnate);
- phenothiazines such as chlorpromazine (Thorazine), fluphenazine (Permitil, Prolixin), perphenazine (Trilafon), prochlorperazine (Compazine, Compro), promethazine (Pentazine, Phenergan, Anergan, Antinaus), thioridazine (Mellaril), or trifluoperazine (Stelazine); or
- an antidepressant such as amitriptyline (Elavil, Vanatrip), doxepin (Sinequan), desipramine (Norpramin), imipramine (Janimine, Tofranil), nortriptyline (Pamelor), and others.
