Seroquel Side Effects
Common Seroquel side effects include dry mouth, dizziness, high triglycerides (determined by a blood test), and headaches. While side effects, if they occur, are typically minor and easily treated, some problems may require immediate medical attention. These side effects of Seroquel that should be reported to a healthcare provider right away include abnormal muscle movements, signs of diabetes, and rapid weight gain.
As with any medicine, side effects are possible with Seroquel® (quetiapine fumarate). However, not everyone who takes the drug will experience side effects. In fact, most people tolerate it quite well. If 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 Seroquel. Your healthcare provider can discuss a more complete list of Seroquel side effects with you.)
Seroquel 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 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 Seroquel side effects included:
- Drowsiness -- in up to 53 percent of people
- Dry mouth -- up to 44 percent of people (see Seroquel and Dry Mouth)
- High triglycerides -- up to 23 percent
- Weight gain -- up to 23 percent (see Seroquel and Weight Gain)
- Headaches -- up to 21 percent
- Agitation -- up to 20 percent
- Dizziness -- up to 18 percent
- High cholesterol -- up to 17 percent
- Fatigue -- up to 11 percent
- Weakness -- up to 10 percent
- Constipation -- up to 10 percent.
Some other common side effects (occurring in 2 to 10 percent of people taking the drug) included:
- Indigestion or heartburn
- Increased appetite
- Nasal congestion
- Abdominal pain (stomach pain)
- Back pain
- Shakiness (tremor)
- Joint pain
- Sore throat
- Rapid heart rate (tachycardia)
