Adverse effects of medications: Diarrhea

Hello! Today we are looking at a question about medication side effects, specifically identifying which medications can cause diarrhea. Since this is a select all that apply question, we need to evaluate each option individually.

Let's start with Aluminum-containing antacids. For these, it is helpful to remember a simple mnemonic. Aluminum equals constipation. Therefore, this is not an expected cause of diarrhea.

Next, we have Anticholinergics or antispasmodics. These drugs work by blocking acetylcholine, which slows down the digestive system. This typically results in constipation and dry mouth, not diarrhea.

Thirdly, let's look at Antibiotics. Antibiotics are very well-known for causing diarrhea. They often disrupt the natural flora of the gut, leading to loose stools or sometimes even serious conditions like C. diff infections.
