Benicar (olmesartan) is an angiotensin receptor blocker (ARB) that is used by patients with high blood pressure. Olmesartan works by relaxing the blood vessels allowing the blood to flow more easily. In turn, this medication helps lower one’s blood pressure level. A regulated level of blood pressure is important in order to reduce the risk of a heart attack or stroke. 

Always use benicar (olmesartan) as directed by one’s physician. Take this medication orally, usually 1 to 2 times daily with or without food. If you are taking the liquid form of benicar, ensure precise measuring of dosage by using a special measuring device. If you also take medications for high cholesterol, avoid drug interactions by taking benicar at least 4 hours beforehand. Because most people with high blood pressure don’t feel sick it can be hard to feel the need to take your dose. However, it’s an important preventative measure to continue taking one’s prescribed dosage even if you feel well. To see the most benefits, take olmesartan regularly. Take it at the same time every day to make it easy to remember.


Prior to using the medication, consult with your doctor if you:

  • Are allergic to olmesartan or anything else in Benicar
  • Have a history of kidney or liver disease, or severe loss of body water (dehydration)
  • Are pregnant or breast-feeding

Benicar can make you dizzy so refrain from activities that require alertness such as driving. At least until you are sure of the effects. Limit alcoholic beverages and consult your doctor, if you are using cannabis as that, can make you dizzier. If your condition doesn’t improve or worsens, let your physician know immediately.

Side Effects

Side effects include but are not limited to:

  • Dizziness/light headedness

Stop taking Benicar and get immediate medical help if you experience any of these rarer symptoms:

  • Fainting
  • Severe and/or persistent diarrhea
  • Signs of kidney disease
  • Signs of a high potassium blood level
  • A severe allergic reaction

If any of these effects persist or worsen immediately tell your doctor or pharmacist.


Q: Do I need to tell my other health care providers that I take Benicar?

A: Yes, all your doctors, pharmacists, nurses, and even your dentist should be aware that you are on this medication.


Q: What should I do if I feel extremely dizzy after taking this medication?

A: One can take precautions such as rising slowly if you’ve been sitting or lying down. Be extra cautious going up the stairs. If the dizziness is severe and persistent, contact your doctor and get medical help immediately.


Q: How is Benicar best taken?

A: Benicar (olmesartan) is best taken as prescribed by your doctor. Follow all directions and read all the information provided to you.

I've been a Canadian Med Center customer for about 6 years now. In all that time there was never once that I considered taking my business elsewhere. They do a great job and the people they contract with are also super.

Always appreciate their prompt service but especially appreciate their hanging in there when there was difficulty getting my doctor to renew my prescription!
