Clozapine Oral Suspension Side Effects
Clozapine oral suspension has been studied extensively in clinical trials. In these studies, the side effects that occurred in a group of people taking the drug were carefully documented and compared to a similar group of people not taking it. Therefore, it was possible to see what side effects occurred, how often they appeared, and how they compared to the group of people not taking the medication.
In these studies, the most common clozapine oral suspension side effects included:
- Increased salivation -- in up to 48 percent of people
- Sedation -- up to 46 percent
- Weight gain -- up to 31 percent (see Clozapine and Weight Gain)
- Dizziness or vertigo (a whirling or spinning sensation) -- up to 27 percent
- Constipation-- up to 25 percent
- A fast heart rate (tachycardia) -- up to 25 percent
- Insomnia -- up to 20 percent (see Clozapine and Insomnia)
- Nausea and vomiting -- up to 17 percent
- Indigestion or heartburn -- up to 14 percent
- Low blood pressure (hypotension) -- up to 13 percent
- Fever -- up to 13 percent.
Other common reactions, occurring in 2 percent to 12 percent of people, included but were not limited to:
- High blood pressure (hypertension)
- Dry mouth (See Clozapine and Dry Mouth)
- Vision problems
- Nightmares and problems sleeping
- Rigid muscles

You may experience some or none of the side effects listed in this article. Unfortunately, there is no way for your healthcare provider to know beforehand if you will have problems with a medicine that you have never tried.
Therefore, make sure to let your healthcare provider know if you develop any side effects while taking clozapine oral suspension or if something "just does not seem right." While it may not be related to the medication, your healthcare provider will be able to diagnose and treat the problem.
