Cycloset Side Effects
Nausea, headaches, and general weakness are among the most common side effects that have been reported with Cycloset. In most cases, problems with this drug are mild, requiring little (if any) treatment. Certain side effects are potentially serious, however, and should be reported to your healthcare provider, including hallucinations, low blood sugar, or hives.
As with any medicine, side effects are possible with Cycloset™ (bromocriptine mesylate). However, not everyone who takes the medication will have problems. 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 can easily be treated by you or your healthcare provider.
(This article covers many, but not all, of the possible side effects with Cycloset. Your healthcare provider can discuss a more complete list of Cycloset side effects with you.)
Cycloset has been studied thoroughly in clinical trials. In these studies, the side effects that occurred in a group of people taking Cycloset were documented and compared to side effects that occurred in a similar group of people taking a placebo (a "sugar pill" with no active ingredients). This way, it is possible to see what side effects occurred, how often they appeared, and how they compare to the group taking the placebo.
In these studies, the most common side effects with Cycloset included:
- Nausea -- in up to 32.5 percent
- General weakness -- up to 18.9 percent
- Headache -- up to 16.8 percent
- Dizziness -- up to 14.8 percent
- Fatigue -- up to 13.9 percent
- Runny or stuffy nose -- 13.8 percent.
Other common side effects (which occurred in 5 to 12.5 percent of people) included:
- Sinus infection or irritation
- A "lazy eye" (amblyopia)
- Indigestion or heartburn
- The common cold
- Flu symptoms (such as a fever and chills)
- Loss of appetite
It should be noted that some of the studies used Cycloset in combination with other diabetes medications, and some of the side effects may be at least partially attributed to the other diabetes medications.
