Blood Pressure Medication: What Works and What to Watch For

High blood pressure often has no symptoms, yet the right medicine cuts your risk of heart attack and stroke. If you or a loved one is starting treatment, clear facts and simple steps matter. Below you'll find the main drug types, when doctors pick them, common side effects, and everyday safety tips.

Main types of blood pressure drugs

ACE inhibitors (like lisinopril) lower pressure by relaxing blood vessels. Doctors often pick them for people with diabetes or kidney issues. Common side effects: cough, dizziness, and a small risk of high potassium.

ARBs (like losartan) work similarly but usually don’t cause that dry cough. They’re a good alternative if ACE inhibitors aren’t tolerated.

Beta blockers (like metoprolol) slow the heart and help in people with heart disease or after a heart attack. Expect tiredness, cold hands, or slower pulse in some people.

Calcium channel blockers (like amlodipine) relax vessel walls and are often used when other drugs don’t control pressure. Side effects can include swelling in the ankles and occasional constipation.

Diuretics (often called water pills, like hydrochlorothiazide) help your body remove extra salt and water. They’re cheap and effective, but watch for low potassium and increased urination.

There are other options—alpha blockers, central-acting drugs, and direct vasodilators—used when standard choices don’t work or cause problems.

How to pick the right medicine

Doctors choose drugs based on your whole picture: age, other health conditions (diabetes, kidney or heart disease), current meds, and side effect risks. Often treatment starts with one drug. If that doesn’t reach your target, doctors add a second with a different action. Combination pills can simplify your routine.

Keep a simple log of blood pressure readings at home. Bring it to appointments so your doctor can see trends—not just single numbers. Ask: what’s my target, how soon should I see improvement, and what side effects should make me call?

Some medicines and common products raise blood pressure: NSAIDs (like ibuprofen/Motrin), decongestants, certain antidepressants, and excessive alcohol. Also tell your doctor about herbal supplements; some can interfere with your drugs.
