Crestor Side Effects
As with any medicine, some people experience side effects when taking Crestor. Some of the side effects that are commonly seen with this medication include muscle aches, headache, constipation, nausea, and abdominal pain. In most cases, these problems are minor and the person does not need to stop taking Crestor. Less than 1 percent of people experience rare side effects of Crestor, such as muscle breakdown, hepatitis, and allergic reactions.
As with any medicine, there are possible side effects with Crestor® (rosuvastatin calcium). However, not everyone who takes this medicine will have problems. In fact, most people tolerate it 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. In previous research studies, up to 5.6 percent of people taking Crestor stopped their prescription because of side effects.
If you experience unexplained muscle pain, tenderness, or weakness (especially if they are accompanied by a fever or body aches), it is important to contact your healthcare provider immediately. These could be signs of a rare, but serious, side effect.
(This article covers many, but not all, of the possible side effects with Crestor. Your healthcare provider can discuss a more complete list of Crestor side effects with you.)
Crestor has been studied extensively 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 Crestor included:
- Muscle aches or pain (see Crestor and Muscle Pain) -- up to 12.7 percent
- Joint pain -- up to 10.1 percent
- Headache -- in up to 8.5 percent of people
- Nausea -- up to 6.3 percent
- Constipation -- up to 4.7 percent
- Body weakness (asthenia) -- up to 4.7 percent
- Dizziness -- up to 4 percent
- Abdominal pain (stomach pain) -- up to 2.4 percent.
