Ziprasidone Side Effects
Some of the more commonly reported ziprasidone side effects include headaches, weight gain, drowsiness, and nausea. Less common side effects (occurring in less than 2 percent of people taking the drug) can include nose bleed, dry eyes, and anemia. Certain side effects of ziprasidone are more serious and should be reported to a healthcare provider. Among these side effects are suicidal thoughts, excessive or rapid weight gain, and abnormal muscle movements.
As with any medicine, there are possible side effects with ziprasidone hydrochloride (Geodon®). However, not everyone who takes the medication will experience side effects. In fact, most people tolerate ziprasidone 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 ziprasidone. Your healthcare provider can discuss a more complete list of ziprasidone side effects with you.)
Ziprasidone 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, the most common ziprasidone side effects included:
- Drowsiness -- in up to 31 percent of people
- Headaches -- up to 18 percent
- Dizziness -- up to 16 percent
- Nausea -- up to 10 percent
- Weight gain -- up to 10 percent (see Geodon and Weight Gain)
- Constipation -- up to 9 percent
- Indigestion or heartburn -- up to 8 percent
- Respiratory tract infections -- up to 8 percent.
Some other common ziprasidone side effects (occurring in 2 percent to 6 percent of people) included:
- Vision problems
- Accidental injury
- Dry mouth (see Geodon and Dry Mouth)
- An irritated or runny nose
- Increased salivation
- Chest pain
- A sore throat
- A rapid heart rate (tachycardia)
