Benicar® (Olmesartan Medoxomil) is used to treat high blood pressure as well as reduce the risk of heart attack and stroke. Benicar® is an angiotensin II receptor blocker, angiotensin is a protein produced by the body that controls blood pressure and affects the cardiovascular system, when angiotensin is released it causes blood vessels to constrict, making it difficult for the heart to pump blood.  Benicar® works by blocking the protein and keeping the body’s blood vessels dilated, increasing blood flow.

Benicar® Side Effects:

The FDA ruled in April of 2014 that Benicar® must include a warning stating its association with some gastrointestinal side effects. Some of these side effects are similar to symptoms of Celiac disease, a digestive disorder resulting from an immune reaction to gluten that can damage the inner lining of the small intestine. Usually, these symptoms are later diagnosed as villous atrophy or sprue-like enteropathy which are serious complications that can also result in intestinal damage, as well as malnutrition and chronic stomach issues.

Researchers at the Mayo Clinic contacted the FDA after noticing a link between patients with symptoms similar to Celiac disease and Benicar®. The researchers tested 22 patients with Celiac symptoms including significant weight loss, chronic diarrhea, and the inability to properly absorb nutrients. While the tests results for Celiac disease were negative, the researchers discovered that all of the patients were prescribed Benicar®.
