Hypertension Medication

High blood pressure affects about one-third of adults. If your doctor prescribes medication, you probably want to know what each drug does, what side effects to watch for, and how to use them safely. This page breaks down the main medicine types, quick rules for special cases, and simple tips to make treatment work for you.

Common drug types and how they work

Doctors choose medicines based on your health, other drugs you take, and how high your blood pressure is. Here are the main classes:

Thiazide diuretics (like hydrochlorothiazide) help your body remove extra salt and water. They’re often a first choice for mild to moderate hypertension. Watch for low potassium and increased urination.

ACE inhibitors (lisinopril, enalapril) relax blood vessels by blocking a hormone that tightens them. They’re good for people with diabetes or heart disease but avoid them in pregnancy.

ARBs (losartan, valsartan) work like ACE inhibitors but with fewer cough side effects. Also not for pregnancy.

Calcium channel blockers (amlodipine, diltiazem) lower pressure by relaxing vessel walls and slowing heart rate in some cases. Common side effects are swelling in the ankles and headaches.

Beta blockers (metoprolol, atenolol) slow the heart and reduce workload. They’re helpful after a heart attack or for certain rhythm issues, but can cause fatigue or cold hands.

Practical tips: using meds safely

Keep a list of all medicines and supplements — many over-the-counter drugs, like NSAIDs, can raise blood pressure or blunt your pills’ effects. Get baseline blood tests when starting ACE inhibitors or ARBs (kidney function and potassium) and repeat as your doctor recommends.

If you have diabetes, kidney disease, or are pregnant (or might become pregnant), tell your doctor. ACE inhibitors and ARBs can harm a fetus and are usually swapped for safer options like labetalol, nifedipine, or methyldopa in pregnancy.

Missed doses matter. Set a routine: same time each day, use phone reminders, or keep pills with something you use daily (toothbrush, coffee mug). Don’t stop meds suddenly — blood pressure can rebound.

Lifestyle changes boost medicine effects: cut sodium, lose excess weight, eat more vegetables, limit alcohol, and move regularly. Even small changes often let you use lower doses.

Know warning signs that need quick care: very high readings (180/120 or higher), sudden severe headache, chest pain, shortness of breath, or confusion. Contact your doctor or emergency services right away.
