If your prescription for any of the following high blood pressure medications has expired, you may be eligible for a new one through Amazon Clinic:

• Angiotensin-converting enzyme (ACE) inhibitors. Options include lisinopril (Prinivil, Zestril), benazepril (Lotensin), captopril, and others.

• Angiotensin II receptor blockers (ARBs). Options include candesartan (Atacand), losartan (Cozaar), and others.

• Beta blockers. Options include metoprolol (Toprol XL, Lopressor), atenolol (Tenormin), and others.

• Calcium channel blockers. Options include amlodipine (Norvasc), diltiazem (Cardizem, Tiazac), and others.

• Combination medications

• Diuretics (water pills). Options include furosemide (Lasix), hydrochlorothiazide (Microzide), and others.

Please note: This information is for general reference only. Your clinician will review your symptoms and health history to determine which (if any) high blood pressure treatments are medically necessary.

Your clinician will need a blood pressure reading and a heart rate reading (pulse) from the past 30 days. If you don't have these numbers, visit your local pharmacy or primary care doctor to get them before you fill out your intake form.

If you want blood pressure medication refills beyond a one-time prescription renewal, your clinician will need to see the results of electrolyte and kidney function level tests from the past 12 months (called "metabolic labs"). You can upload your metabolic lab results as a PDF or photo. If you upload a photo, make sure it shows your full name and the date the labs were completed.

No. Electrolyte and kidney function testing ("metabolic labs") isn't available through Amazon Clinic at this time.

No, you can't get a hypertension diagnosis through Amazon Clinic. Diagnosing hypertension often needs multiple readings over time. We recommend having your blood pressure elevated by a primary care provider (PCP).

If you've been diagnosed with hypertension, taking high blood pressure medication is one of the most effective ways you can lower your risk of experiencing a major cardiovascular event like a heart attack or stroke.

Research shows that high blood pressure medications reduce overall risk by:

• Up to 64% for heart failure

• 35-40% for stroke

• 15-25% for heart attack

In fact, every 10mm Hg reduction in systolic blood pressure can reduce one's risk of having a major cardiovascular disease event by 20%, according to a meta-analysis in the medical journal The Lancet.

Even if you're taking high blood pressure medication, clinicians still recommend that you try to modify any lifestyle factors that are proven to contribute to hypertension:

• Obesity or weight gain

• High salt intake

• High alcohol consumption

• Physical inactivity

• Insufficient sleep

When you run out of your medication, you refill it through a pharmacy. When you run out of refills, a licensed clinician has to renew your prescription.

You can get a prescription renewal through Amazon Clinic. This renewal may be for a 30-day supply of medication, or it may include refills. Your clinician can send your new prescription to a U.S. pharmacy of your choice where you can pick up your medication or have it delivered to you.
