Antara Side Effects
Many potential side effects may develop as a result of using Antara. Side effects that were seen in more than 2 percent of patients included abdominal pain, chest congestion, and back pain. Less common problems that may occur include depression, joint pain, and weight gain. Examples of serious side effects of Antara that should be reported to a healthcare provider immediately include fever, itching, and unexplained bleeding.
As with any medicine, side effects are possible with Antara® (fenofibrate), but not everyone who takes the drug will have side effects. In fact, most people tolerate it quite well. If side effects do occur, they are usually minor and either require no treatment or can easily be treated by you or your healthcare provider. In previous research studies, up to 5 percent of people taking Antara stopped their medicine because of side effects.
The use of Antara has been associated with a rare but serious side effect known as rhabdomyolysis (serious breakdown of muscles). Contact your healthcare provider immediately if you experience any unexplained muscle pain, tenderness, or weakness, especially if accompanied by a fever or unusual tiredness (see Antara and Muscle Pain).
(This article covers many, but not all, of the possible side effects with Antara. Your healthcare provider can discuss a more complete list of Antara side effects with you.)
Antara has been studied thoroughly in clinical trials. In these studies, side effects are always documented and compared to side effects that occurred in a similar group of people not taking the medicine. The most common Antara side effects occurred in more than 2 percent of the people taking Antara and included:
- Chest congestion or difficulty breathing -- up to 6.2 percent
- Abdominal pain -- up to 4.6 percent
- Back pain -- up to 3.4 percent
- Headache -- up to 3.2 percent
- Runny nose -- up to 2.3 percent
- Diarrhea or constipation -- up to 2.3 percent
- Nausea -- up to 2.3 percent
- Body weakness -- up to 2.1 percent
- Flu-like symptoms -- up to 2.1 percent.
Antara can also cause an elevation in liver enzymes. In the clinical trials, this was the most common reason why people stopped taking the drug. Your healthcare provider may choose to monitor your liver enzymes during your treatment and stop your medication if they become too high (see Antara and Liver Problems).
