Olmesartan, a medication primarily used to treat high blood pressure and protect the kidneys from damage due to diabetes, is an angiotensin II receptor antagonist (ARB). While it is effective in managing these conditions, like any medication, it comes with potential side effects. Understanding these side effects is crucial for patients and healthcare providers to make informed decisions about treatment. This article aims to provide a comprehensive overview of the side effects associated with olmesartan, including common, less common, and rare but serious effects.
Common Side Effects of Olmesartan
Most patients taking olmesartan experience mild side effects that typically resolve on their own. The most commonly reported side effects include:
- Dizziness or lightheadedness
- Headache
- Fatigue
- Sleep disturbances
- Nausea
- Diarrhea
- Abdominal pain
These side effects are usually mild and temporary. However, if they persist or become severe, it is essential to consult a healthcare provider.
Less Common but Potentially Serious Side Effects
While less common, some side effects of olmesartan can be serious and require immediate medical attention. These include:
- Signs of an allergic reaction (hives, difficulty breathing, swelling of the face, lips, tongue, or throat)
- Severe or persistent diarrhea with weight loss
- Nausea or vomiting
- Abnormal heart rhythms
- Shortness of breath
- Chest pain
Patients should seek emergency medical help if they experience any of these symptoms.

This condition can be misdiagnosed as celiac disease or other gastrointestinal disorders. If patients experience persistent gastrointestinal symptoms, they should discuss this possibility with their healthcare provider.
