Over-the-counter (OTC) drugs are typically considered safe when taken at the recommended doses. But take the right amount for a little too long and you could run into some unexpected side effects. Experts from the U.S. Food & Drug Administration (FDA) have issued a warning about one OTC medication that they say can trigger serious heart symptoms if taken in excess. In fact, they warn that if your symptoms persist for longer than two days while taking this drug, you should stop immediately and call your doctor.

Prolonged use of loperamide can cause a wide range of side effects, but there’s another reason you shouldn’t take it for longer than two days.

In particular, the health authority points out that loperamide should not be used by individuals with dysentery, enterocolitis caused by bacteria, pseudomembranous colitis, stomach pain without diarrhea, and ulcerative colitis.
The Mayo Clinic further warns that “certain medical conditions and infections—bacterial and parasitic—can be worsened by these medications because they prevent your body from getting rid of what’s causing the diarrhea.” Speak with your doctor if you…
