Schizophrenia Home > Navane Side Effects

Most people tolerate Navane well. However, side effects may still occur during treatment with the antipsychotic drug. Drowsiness, insomnia, and dry mouth are a few of the side effects reported in clinical trials. Other Navane side effects -- such as seizures, worsening psychotic symptoms, and signs of an allergic reaction -- are more serious and should be reported to a healthcare provider.

An Introduction to Navane Side Effects

As with any medicine, there are possible side effects with Navane® (thiothixene). However, not everyone who takes Navane will experience side effects. In fact, most people tolerate Navane well. When side effects do occur, in most cases they are minor and either require no treatment or are easily treated by you or your healthcare provider.
(This article covers many, but not all, of the possible side effects with Navane. Your healthcare provider can discuss a more complete list of Navane side effects with you.)

Possible Navane Side Effects

Navane 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 possible Navane side effects included:
  • Drowsiness
  • Insomnia
  • Dry mouth (see Navane and Dry Mouth)
  • Blurred vision
  • Nasal congestion
  • Constipation
  • Increased sweating
  • Increased salivation (which can cause drooling)
  • Nausea and vomiting
  • Diarrhea
  • Increased or decreased appetite
  • Weight gain
  • Weakness or fatigue
  • Thirst
  • Swelling or water retention in the hands, legs, or feet.
