MedDataToolHyoscyamine ER is a medication used to help treat conditions like peptic ulcers, irritable bowel syndrome, and bladder issues by reducing stomach acid and controlling muscle spasms. It works by blocking a substance in the body that causes these muscles to contract, helping to relieve symptoms. You take it as a tablet, starting with 1 to 2 tablets every 12 hours, but you should not exceed 4 tablets in a day. It's important to know that it can cause drowsiness, so you should be careful when driving or operating machinery. Additionally, if you have glaucoma or certain types of bowel obstructions, you should not use this medication.
