Edarbi (Azilsartan) - Oral


The United States Food and Drug Administration (FDA) has issued a boxed warning for Edarbi. Boxed warnings are the agency’s strongest warnings for serious and potentially life-threatening risks. Review these warnings and discuss your concerns with your healthcare provider before starting treatment.

The boxed warning:

  • When pregnancy is detected, discontinue Edarbi as soon as possible.
  • Drugs that act directly on the renin-angiotensin system can cause injury and death to the developing fetus.

What Is Edarbi?

Edarbi (azilsartan) is a prescription medication administered orally that is used alone or in combination therapy to treat hypertension (high blood pressure). Edarbi belongs to the class of drugs called angiotensin II receptor antagonists (ARBs), a group of medications prescribed to treat hypertension. Within the body, angiotensin II (a naturally occurring hormone) causes the blood vessels to tighten and become narrow.

To combat this, Edarbi selectively inhibits angiotensin II from binding to specific receptors allowing the blood vessels to relax and widen. As a result, the medication causes the blood to flow more easily through blood vessels to reduce blood pressure.

Edarbi is available as an oral tablet.

To help you remember, take medicine at the same time each day. Keep taking Edarbi even if you feel well. Consult your healthcare provider if your condition does not improve or worsen.


Store tablets in the original container at room temperature, away from light and moisture. Do not put the tablets in a different container. Do not store it in the bathroom or other areas prone to high levels of moisture. Keep all drugs locked away from the reach and sight of children and pets.

Do not keep unwanted or expired medication with you. Don't throw medicines in a waste bin, flush medications down the toilet, or pour them into a drain unless instructed to do so. Discard unwanted or expired medication by consulting your pharmacist or local waste disposal company.

It is very important that your doctor check your progress at regular visits to make sure this medicine is working properly. Blood tests may be needed to check for unwanted effects.

Using this medicine while you are pregnant can harm your unborn baby. Use an effective form of birth control to keep from getting pregnant. If you think you have become pregnant while using this medicine, tell your doctor right away.

Dizziness, lightheadedness, or fainting may occur, especially when you get up from a lying or sitting position or if you have been taking a diuretic (water pill). Make sure you know how you react to this medicine before you drive, use machines, or do anything else that could be dangerous if you are dizzy or not alert. If you feel dizzy, lie down so you do not faint. Then sit for a few moments before standing to prevent the dizziness from returning. If you faint, call your doctor right away.

Check with your doctor right away if you become sick while taking this medicine, especially with severe or continuing nausea, vomiting, or diarrhea. These conditions may cause you to lose too much water and may lead to low blood pressure. You can also lose water by sweating, so drink plenty of water during exercise or in hot weather.

Do not take other medicines unless they have been discussed with your doctor. This especially includes nonprescription medicines for appetite control, asthma, colds, cough, hay fever, or sinus problems, since they may tend to increase your blood pressure.

What Are Reasons I Shouldn't Take Edarbi?

Edarbi is not appropriate for everyone. You should not take this medication if you are allergic to azilsartan or any of the inactive ingredients in Edarbi.

Edarbi may be discouraged in some people only if the healthcare provider determines it is unsafe. This includes:

  • Pregnant people should not consume ARBs. Edarbi (azilsartan) is a teratogenic drug (a drug that is toxic to a fetus or embryo). If taken during early pregnancy, the risk of congenital abnormalities (e.g., heart defects, neural tube defects, and Down syndrome) increases greatly.
  • ARB drugs are also fetotoxic (a substance or agent that can poison or cause degenerative effects in a developing fetus or embryo) during the second and third trimesters. Therefore, if a pregnant person has previously been on any ARB such as Edarbi and becomes pregnant immediately (within two days of pregnancy confirmation), discontinue Edarbi.

What Other Medications May Interact With Edarbi?

Tell your healthcare provider about all of the medicines you take, including prescription and over-the-counter (OTC) medicines, and vitamins or supplements. 

The following medications can increase the risk of toxicity when taken with Edarbi:

Edarbi is metabolized by the CYP2C9 enzyme — a gene that provides instructions for making an enzyme that is found in a cell structure called the endoplasmic reticulum (the primary transportation system of the eukaryotic cell). Therefore, users should be aware that caution is recommended when taking Edarbi along with strong activators of this enzyme, such as Jantoven (warfarin).

What Medications Are Similar?

Other drugs belonging to the class of ARBs include:

Edarbi is relatively a new addition to the ARB class of antihypertensive agents. It received FDA approval in 2011.

Various clinical studies have shown that Edarbi works better than many of the other drugs in its class. Edarbi, at its maximal dose, has superior efficacy to other ARBs, such as olmesartan and valsartan, at their maximal, approved doses without increasing adverse effects. It could provide higher rates of hypertension management within the ARB class.
