What is olmesartan medoxomil and how does it work?
Olmesartan medoxomil is an angiotensin II receptor blocker (ARB). It works by blocking a natural substance in the body that tightens blood vessels. When those blood vessels relax and widen, blood flows more easily and blood pressure comes down.
It is FDA-approved to treat hypertension (high blood pressure) in adults and in children 6 years and older, either on its own or together with other blood pressure medicines. Lowering high blood pressure helps reduce the risk of fatal and non-fatal cardiovascular events, mainly strokes and heart attacks.

Safety and side effects to know
Olmesartan medoxomil carries a boxed warning for fetal toxicity: medicines that act on the renin-angiotensin system can injure or cause the death of a developing baby. If you become pregnant or are planning to, tell your doctor right away, as this medicine is usually stopped as soon as pregnancy is detected. The most common side effect is dizziness.
Other important risks include low blood pressure (especially if you are dehydrated or low on salt), reduced kidney function, and high potassium levels. A rare but serious condition called sprue-like enteropathy can cause severe, ongoing diarrhea with weight loss months or even years after starting, and it improves after the medicine is stopped. Angioedema (serious swelling) has also been reported. Olmesartan is not a controlled substance. This is general information, not medical advice; talk with your provider or pharmacist about your personal risks and any side effects you notice.
