Mental Health Home > Mellaril Side Effects
Hyperactivity, weight gain, and a dry mouth are some of the most common side effects reported with Mellaril. Side effects of this medicine are mostly minor, requiring little or no treatment. However, certain side effects are more serious and should be reported to a healthcare provider. Among these more serious side effects are irregular heart rhythms, worsening of psychotic symptoms, and unusual body movements.
As with any medicine, there are possible side effects with Mellaril® (thioridazine). However, not everyone who takes the medication will experience side effects. In fact, most people tolerate Mellaril 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 Mellaril. Your healthcare provider can discuss a more complete list of Mellaril side effects with you.)
Mellaril 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 Mellaril side effects included:
- Dry mouth (see Mellaril and Dry Mouth)
- Blurred vision
- Difficulty passing urine
- Nausea, vomiting, or diarrhea
- Ejaculation problems
- A loss of appetite
- Weight gain
- Bizarre dreams.
There have been reports that Mellaril may cause false positive pregnancy tests (a positive pregnancy test in an individual who is not pregnant).
