Compazine Side Effects
Headaches, nasal congestion, and drowsiness are some of the side effects of Compazine that have been seen in clinical studies. Certain side effects are more serious than others and should be reported to a healthcare provider. Among these serious side effects are low blood pressure, seizures, and an irregular heart rhythm.
As with any medicine, side effects are possible with Compazine® (prochlorperazine maleate). However, not everyone who takes the medication will experience side effects. In fact, most people tolerate it well. If 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 Compazine. Your healthcare provider can discuss a more complete list of Compazine side effects with you.)
Compazine 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 those 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 possible Compazine side effects included:
- Menstrual changes (especially missed periods)
- Blurred vision
- Dry mouth (see Compazine and Dry Mouth)
- Nasal congestion
- Ejaculation problems
- Impotence, also known as erectile dysfunction or ED (see Compazine Sexual Side Effects)
- Difficulty passing urine
- Sensitivity to the sun
- Increased appetite (and weight gain).
There have been reports that Compazine may cause false positive pregnancy tests (a positive pregnancy test in an individual who is not pregnant).
