Erbitux Side Effects
In clinical trials, up to 89 percent of people reported itching, peeling, irritation, and dry skin as side effects of Erbitux. Although adverse reactions are expected, they are typically mild and easily treated. Potentially serious problems with this drug include sudden wheezing, difficulty breathing, severe diarrhea, and chest pain. These and other reactions should be reported to a healthcare provider.
An Introduction to Erbitux Side EffectsJust like any medicine, Erbitux® (cetuximab) can cause side effects. Not everyone who uses the medication will have problems. However, most people will experience some type of adverse reaction during treatment. If problems 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 Erbitux. Your healthcare provider can discuss a more complete list with you.)
Common Side Effects With ErbituxErbitux has been studied thoroughly in clinical trials. In these studies, the side effects that occurred in a group of people receiving Erbitux were carefully documented and compared to those that occurred in a similar group of people receiving a placebo (an injection with no active ingredients), a different anti-cancer medication, or radiation treatment. As a result, it was possible to see what side effects occurred, how often they appeared, and how they compared to the placebo or other treatments.
In these studies, the most common Erbitux side effects included:
- Skin reactions, including acne-like rash, itching, irritation, peeling, and dry skin -- up to 89 percent
