How Olmesartan (Benicar) works
Olmesartan (Benicar) is an angiotensin II receptor blocker (ARB). Angiotensin II is a hormone that acts on multiple areas in the body. When it acts on the blood vessels, the blood vessels narrow, which raises blood pressure.
Olmesartan (Benicar) blocks angiotensin II in the blood vessels. In doing so, this medication tells the blood vessels to relax, which helps to lower blood pressure.

Pharmacist tips for Olmesartan (Benicar)
- You might feel dizzy when you start taking olmesartan (Benicar), and when the dose is raised. This should get better over time as you continue taking the medication and your body gets used to your new blood pressure.
- Make sure to mark your calendar with your appointments to see your provider and to get any blood work done when you take olmesartan (Benicar). Your provider might order tests (e.g., potassium level, kidney function, blood pressure) during treatment and might change your dose of olmesartan (Benicar) based on your lab results.
- Take olmesartan (Benicar) exactly as prescribed. Don't change your dose or suddenly stop taking the medication without talking to your provider first. Doing so can cause your blood pressure to rise quickly. If you want to stop olmesartan (Benicar), ask your provider if it's safe to do so. You might need to lower your dose slowly over time before you can completely stop taking it.
- Let your provider know if you experience severe diarrhea that doesn't seem to get better over time. This can be a rare, but serious, side effect of olmesartan (Benicar). It's possible to develop stomach problems even months or years after starting olmesartan (Benicar). And if left untreated, this can lead to weight loss and cause electrolyte levels to be out of balance. If you experience severe diarrhea, your provider might need to switch you to a different medication.
- Olmesartan (Benicar) can raise your potassium levels, which can be serious. Contact your provider if you experience nausea, vomiting, or muscle weakness because these might be signs of high potassium levels.
- It's recommended you measure and record your blood pressure at home and bring a record to your medical appointments. This will help your provider see how well the medication is working for you and guide any dose changes.
- Make sure to have a healthy diet, including a low-salt diet, while taking olmesartan (Benicar) to help lower your blood pressure. Depending on your risk factors and other medical problems, it's possible you might be able to stop taking olmesartan (Benicar) if your blood pressure gets within goal.
- Don't use non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen (Advil, Motrin), while taking olmesartan (Benicar) unless your provider specifically said it was safe for you to do so. This is because taking NSAIDs and olmesartan (Benicar) together can cause kidney problems.
Risks and warnings for Olmesartan (Benicar)
Olmesartan (Benicar) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Harm to unborn babies
Olmesartan (Benicar) shouldn't be used in pregnant females because it can cause severe harm and even death to unborn babies. If you find out that you're pregnant while taking olmesartan (Benicar), stop and let your provider know right away. If you're pregnant before starting olmesartan (Benicar) or thinking of becoming pregnant during treatment, discuss with your provider about safer options to treat your blood pressure.
Low blood pressure (in people who are dehydrated)
- Risk factors: Not enough fluid in your body (dehydration) | Having diarrhea or vomiting for a long time | Low salt levels in your body | Taking higher doses of diuretic mediations
Olmesartan (Benicar) is taken to lower blood pressure. But sometimes, having a lower blood pressure can be dangerous for certain groups of people, especially those who are dehydrated or those who've lost a lot of body fluids through diarrhea, vomiting, or taking water-pills.
Make sure to stay well-hydrated while taking olmesartan (Benicar). If your blood pressure drops too much and you feel dizzy, make sure to sit down slowly while holding onto something and let your provider know.
Worsening kidney problems
- Risk factors: Kidney problems | Heart failure | Taking medications that affect your kidneys | Not enough fluid in your body
In some people, olmesartan (Benicar) can cause the kidneys to not work as well. The risk is higher if you have certain types of kidney problems, such as renal artery stenosis or very severe heart failure, or if you're taking other medications that can affect your kidneys. Your provider might order blood tests to make sure your kidneys are healthy and working properly. Let your provider know if you're urinating less often than usual or notice any swelling, as these could be signs that your kidneys aren't working as well.
High potassium levels
- Risk factors: Kidney problems | Heart failure | Taking other medications that raise potassium | Use of potassium-containing salt substitutes
Olmesartan (Benicar) can raise the amount of potassium in your body. In some people, this can lead to certain symptoms, such as a tingling sensation, nausea, or muscle weakness. The risk is higher if you're taking other medications that can raise your potassium, or if you have certain medical conditions. Your provider might order blood tests to monitor your potassium on a regular basis.
Severe diarrhea (sprue-like enteropathy)
Rarely, people who take olmesartan (Benicar) experience serious diarrhea (sprue-like enteropathy). Sometimes, this happens months to years after starting the medication. In severe cases, the diarrhea can lead to weight loss, stomach pain, tiredness, nausea, and vomiting. If you experience severe diarrhea that doesn't seem to get better after a few day, get medical help right away. Make sure to stay hydrated with fluids and electrolytes.
