Insomnia, nasal congestion, and difficulty passing urine are some of the more common side effects seen with Thorazine. Side effects of this medicine are mostly minor and easily treated by you or your healthcare provider. However, if you develop serious Thorazine side effects -- such as worsening of psychotic symptoms, seizures, or any signs of an infection -- you should contact your healthcare provider.
As with any medicine, there are possible side effects with Thorazine® (chlorpromazine hydrochloride). However, not everyone who takes the medication will experience side effects. In fact, most people tolerate Thorazine 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 Thorazine. Your healthcare provider can discuss a more complete list of Thorazine side effects with you.)
Thorazine 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 Thorazine side effects included:
- Nasal congestion
- Ejaculation problems
- Impotence, also known as erectile dysfunction or ED (see Thorazine Sexual Side Effects)
- Dry mouth (see Thorazine and Dry Mouth)
- Nausea, vomiting, diarrhea, or constipation
- Difficulty passing urine
- Blurred vision
- Changes in color, from slight darkening to gray or purple shades.
There have also been reports that Thorazine may cause false positive pregnancy tests (a positive pregnancy test in an individual who is not pregnant).
