Common Side Effects of Klonopin
Klonopin has been studied thoroughly in clinical trials in which the side effects of a group of people taking the drug are documented and compared to another group not taking the medicine. As a result, 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 side effects of Klonopin included:
- Drowsiness -- in up to 50 percent of people
- Coordination problems -- up to 30 percent
- Behavior problems -- up to 25 percent
- Dizziness -- up to 12 percent
- Upper respiratory tract infections (such as the common cold) -- up to 10 percent.
Other common Klonopin side effects (occurring in 1 to 10 percent of people) included:
- Speech problems
- A decreased sex drive
- Confusion
- Sinus infections
- An irritated or runny nose
- Coughing
- Sore throat
- Fatigue
- Painful menstrual cramps
- Sexual problems (see Klonopin Sexual Side Effects).
