Blood Pressure Medication: What to Know and How to Choose

High blood pressure is common, but the medicines that treat it aren’t one-size-fits-all. You want something that lowers your numbers, fits your daily life, and has side effects you can live with. This page breaks down the main drug types, what each does, and practical tips so you can talk to your doctor with confidence.

Common drug classes

Here are the main groups you’ll hear about and what they do:

ACE inhibitors (like lisinopril) relax blood vessels by blocking an enzyme. They’re often first choice for people with diabetes or kidney concerns. Watch for a dry cough or swelling.

ARBs (like losartan) work like ACE inhibitors but usually don’t cause cough. They’re a go-to if you couldn’t tolerate an ACE inhibitor.

Beta-blockers (like metoprolol or bisoprolol) slow the heart down and lower pressure. They’re useful after heart attacks or for certain rhythm problems. They can make you feel tired or cold hands and feet.

Calcium channel blockers (like amlodipine) prevent vessels from tightening. They’re handy if other drugs don’t work alone. Some people notice swelling in the ankles or flushing.

Diuretics (thiazide types like hydrochlorothiazide) help your body shed extra salt and water. They’re cheap and effective, but can change potassium or sugar levels, so follow up with blood tests.

Practical tips for taking meds

How you take medicine matters almost as much as which one you take. First, take it the same time every day. Set alarms, link the dose to a routine like brushing your teeth, or use a pillbox.

Check interactions. Some supplements and common drugs change how blood pressure meds work. For example, NSAID painkillers can reduce effectiveness of certain BP medicines. Tell your doctor about all prescription drugs, vitamins, and herbal products you use.

Track side effects for a week or two and tell your clinician. Some effects fade over time, others mean you should switch drugs. If you feel dizzy, very lightheaded, or faint when standing, pause and call your doctor—this may mean your dose is too high.

Don’t stop suddenly. Stopping some blood pressure medicines fast can be risky. If you want to stop or change a drug, plan it with your prescriber.

Finally, lifestyle changes add up. Losing a few pounds, cutting salt, moving more, and limiting alcohol can boost how well your meds work and may let you use lower doses.
