Ethotoin Side Effects
There is limited information available on the possible side effects of ethotoin, as this is an older medication that has not been extensively studied in clinical trials. However, this drug may cause problems, such as diarrhea, fatigue, and double vision. Potentially serious reactions may also occur and can include chest pain, unexplained bruising, or suicidal thoughts.

Just like any medicine, ethotoin (Peganone®) can cause side effects. However, not everyone who takes the drug will have problems. In fact, most people tolerate it quite well. If side effects do occur, in most cases, they are minor and either require no treatment or are treated easily by you or your healthcare provider.
(This article covers many, but not all, of the possible side effects with ethotoin. Your healthcare provider can discuss a more complete list with you.)
