Key takeaways
Dicyclomine (Bentyl) and hyoscyamine (Levsin, Hyosyne, Symax, Oscimin, NuLev) are both anticholinergic medications used to treat irritable bowel syndrome (IBS) and other stomach and intestine problems. Dicyclomine is typically taken four times a day and is available in generic form as tablets, capsules, and liquid. It can also be given as an injection for those who can't take it orally. Common side effects include dizziness, dry mouth, and blurry vision. Hyoscyamine, on the other hand, is taken every four hours and comes in various forms, including immediate-release tablets, sublingual tablets, and oral solutions. It can also be used for conditions like overactive bladder, stomach ulcers, and even colic in babies. Hyoscyamine's side effects include dry mouth, sleepiness, and dizziness. Both medications can cause changes in mood and bodily functions, but hyoscyamine has a broader range of uses and dosage forms. Additionally, hyoscyamine can be used in both adults and children, while dicyclomine is primarily for adults.
