Common Questions about Hyoscyamine


Is hyoscyamine a painkiller?

Hyoscyamine is not a painkiller. It belongs to a group of medications called anticholinergic drugs. Hyoscyamine is used to treat stomach and bladder problems. This medication may, however, provide relief from symptoms such as stomach cramps, gallbladder pain, kidney pain, and bladder spasms.



Does hyoscyamine make you poop?

Hyoscyamine can actually make constipation worse because it has a drying effect in the body. However, this medication may help to relieve other gastrointestinal symptoms like stomach pain and cramps.



What is the best time to take hyoscyamine?

You should take hyoscyamine before meals in general, and at least 1-2 hours away from antacids. Take your medicine exactly as prescribed. Your healthcare provider may ask you to take hyoscyamine 3-4 times a day. If you are on the extended-release (long-acting) hyoscyamine tablets, you will likely be asked to take them twice a day.



How quickly does hyoscyamine work?

Hyoscyamine works pretty quickly. The sublingual, orally disintegrating, and immediate-release tablets work within a few minutes. The effects last 6-8 hours for the immediate-release formulations and 12 hours for the long-acting formulations.



Is hyoscyamine good for diarrhea?

Hyoscyamine should not be used to treat diarrhea. There are other safer and more effective antidiarrheal drugs available. In addition, diarrhea can be an early symptom of bowel obstruction, and taking hyoscyamine in such a situation can make the condition worse.
