Side Effects of Thioridazine
Side effects of thioridazine can include drowsiness, headaches, and a dry mouth. For the most part, thioridazine side effects are minor and don't require medical attention. However, some side effects with thioridazine are more serious and should be reported to a healthcare provider. Among these more serious side effects are unusual body movements, feelings of internal restlessness or jitteriness, and worsening of psychotic symptoms.
As with any medicine, there are possible side effects with thioridazine (Mellaril®). However, not everyone who takes the medication will experience side effects. In fact, most people tolerate thioridazine well. When side effects do occur, in most cases they are minor and either require no treatment or can easily be treated by you or your healthcare provider.
(This article covers many, but not all, of the possible side effects with thioridazine. Your healthcare provider can discuss a more complete list of thioridazine side effects with you.)
Thioridazine has been studied thoroughly in clinical trials. In these studies, the side effects that occur in a group of people taking the drug are documented and are then compared to side effects that occur in another group of people not taking the medicine. This way, it is possible to see what side effects occur, how often they appear, and how they compare to the group not taking the medicine.
In these studies, some common thioridazine side effects included:
- Dry mouth (see Mellaril and Dry Mouth)
- Blurred vision
- Difficulty passing urine
- Nausea, vomiting, or diarrhea
- Ejaculation problems
- Loss of appetite
- Weight gain
- Bizarre dreams.
There have been reports that thioridazine may cause false positive pregnancy tests (a positive pregnancy test in an individual who is not pregnant).
