Azilsartan Medoxomil — What You Need to Know
Azilsartan medoxomil is an ARB (angiotensin II receptor blocker) used to lower high blood pressure. If your doctor suggested it, you probably want straight answers: how to take it, what to watch for, and how it compares to other options. This guide gives clear, useful facts so you can talk to your provider with confidence.
How it works and who should take it
Azilsartan relaxes blood vessels by blocking angiotensin II, a hormone that tightens vessels and raises blood pressure. It’s prescribed for adults with hypertension and often given once daily. Typical doses range from 20 mg to 80 mg a day; most people start at 40 mg. If you’re already on a diuretic or are volume-depleted, doctors may start at a lower dose (for example, 20 mg).
People with kidney disease, diabetes, or heart issues often take ARBs like azilsartan because they protect the kidneys and heart in addition to lowering blood pressure. But azilsartan is not for pregnant women — it can harm the fetus — and it’s not recommended if you have a history of angioedema from an ARB or ACE inhibitor.
Side effects, interactions, and simple safety tips
Common side effects include dizziness, lightheadedness when standing, and sometimes increased potassium or creatinine in blood tests. Serious problems are rare but include symptomatic low blood pressure, high potassium (hyperkalemia), or kidney function changes.
Drug interactions to watch for: avoid combining azilsartan with potassium supplements or potassium-sparing diuretics unless your provider is actively monitoring potassium levels. NSAIDs (like ibuprofen) can reduce the blood-pressure benefit and may affect kidney function when used with ARBs. Be cautious with lithium — ARBs can increase lithium levels. If you’re prescribed other blood-pressure drugs, your provider will adjust doses to prevent too-low blood pressure.
Practical tips: take azilsartan at the same time each day, with or without food. If you feel dizzy, stand up slowly and check your blood pressure. Have blood tests 1–2 weeks after starting or changing dose to check kidney function and potassium. If you miss a dose, take it when you remember unless it’s almost time for the next dose — don’t double up.
How does it compare to other ARBs? Many doctors like azilsartan because it often gives strong, once-daily control. If your current ARB doesn’t lower your BP enough, your provider might switch you to azilsartan or adjust doses. Never switch or stop a blood-pressure drug without talking to your provider.
If you have questions about side effects, pregnancy, or combining azilsartan with other medicines, bring them up at your next appointment. Small checks — home BP readings, a lab test, and a quick chat with your clinician — can keep treatment safe and effective.
