Side Effects of Oxazepam

Dizziness, drowsiness, headaches, and vertigo are a few of the most common side effects of oxazepam. Among the less common side effects with this medicine are lethargy, slurred speech, and swelling. Oxazepam side effects are mostly minor and require little or no treatment. However, a few of the more serious side effects of oxazepam include depression, low blood pressure (hypotension), and signs of an allergic reaction (such as hives, itching, or an unexplained rash).

An Introduction to Side Effects of Oxazepam

As with any medicine, side effects are possible with oxazepam (Serax®); however, not everyone who takes the medication will experience side effects. 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 easily treated by you or your healthcare provider.
 
(This article covers many, but not all, of the possible side effects with oxazepam. Your healthcare provider can discuss a more complete list of oxazepam side effects with you.)
