Berinert Side Effects
Clinical trials have shown that Berinert can cause side effects such as nausea, headaches, and flu-like symptoms. However, most people tend to tolerate the medicine fairly well, and any reactions that occur often are minor and easy to treat. You should contact your healthcare provider if you develop problems that are potentially serious, however, such as chest pain, extreme pain, or changes in speech or vision.
Just like any medicine, Berinert® (C1 esterase inhibitor) can cause side effects. However, not everyone who uses the medication will have problems. In fact, most people tolerate it quite well. If reactions do occur, in most cases, they are minor and either require no treatment or are treated easily by you or your healthcare provider.
(This article covers many, but not all, of the possible side effects with Berinert. Your healthcare provider can discuss a more complete list with you.)
Berinert has been studied extensively in clinical trials. In these studies, the side effects that occurred in a group of people given the drug were carefully documented and (in one study) compared with those that occurred in a similar group of people given a placebo (an injection with no active ingredients). As a result, it was possible to see what side effects occurred, how often they appeared, and how they compared to the placebo.
In clinical studies, the most common Berinert side effects included:
- Nausea -- in up to 7 percent of people
- Headache -- up to 7 percent
- Abdominal (stomach) pain -- up to 7 percent
- Bad taste in the mouth -- up to 4.7 percent
- Symptoms of the common cold, such as a stuffy nose or sore throat -- up to 3.5 percent
- Flu-like symptoms -- up to 3.5 percent
- A rash -- up to 3.5 percent
- Vomiting -- up to 2.3 percent
- Pain -- up to 2.3 percent
- Muscle spasms -- up to 2.3 percent.
