Donnatal is a medication that may help with conditions like irritable bowel syndrome and acute enterocolitis. It works by relaxing the muscles in the gut and providing mild sedation. Adults typically take one or two teaspoonfuls of the elixir three or four times a day, while children are dosed based on their weight every 4 to 6 hours. It's important to know that Donnatal can be harmful to a developing fetus if taken during pregnancy. Additionally, it can interact with blood thinners, meaning that if you take anticoagulants, you may need a higher dose while on this medication.
