Common Buspirone Side Effects
Buspirone has been studied thoroughly in clinical trials. In these studies, the side effects that occurred in a group of people taking the drug were documented and then compared to the side effects that occurred in another group of people taking a placebo (a "sugar pill" that does not contain any active ingredients). As a result, it was possible to see what side effects occurred, how often they appeared, and how they compared to the group not taking the medicine.
In these studies, the most common side effects of buspirone included:
- Dizziness -- in up to 12 percent of people
- Drowsiness -- up to 10 percent
- Nausea -- up to 8 percent
- Headaches -- up to 6 percent
- Nervousness -- up to 5 percent.
Other common side effects, occurring in 1 to 4 percent of people, included:
- Lightheadedness
- Excitability
- Anger or hostility
- Confusion
- Blurred vision
- Diarrhea
- Muscle aches or pains
- Unusual sensations, such as numbness, burning, or tingling
- Coordination problems
- Shakiness (tremor)
- Weakness
- Sweating or clamminess.
Rare Side Effects of Buspirone
Less common side effects occurred in less than 1 percent of people taking the medication. Because these side effects are so rare, it can be difficult to tell whether they are actually caused by buspirone or by other factors unrelated to the medication.
Some of these rare side effects include but are not limited to:
