Dry mouth, lightheadedness, and drowsiness are some of the most common trazodone side effects. Rare side effects include increased appetite, muscle twitches, and increased sex drive. In most cases, side effects are minor and either don't require medical attention or can be easily treated. However, you should contact your healthcare provider immediately if you develop problems such as suicidal thoughts or behavior, hallucinations, or any signs of an allergic reaction.
