What kind of doctor provides Blood Pressure Medication?

A primary care doctor or another health care provider usually prescribes blood pressure medicine. A cardiologist, a doctor who treats heart conditions, may help if you also have a heart condition. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.

What it is

Blood pressure medicines lower high blood pressure, also called hypertension. There are several types, and they work in different ways. Diuretics, also called water pills, help your kidneys remove some salt from your body. ACE inhibitors and ARBs are two types that help relax your blood vessels. This lowers your blood pressure. Calcium channel blockers also relax your blood vessels. Beta-blockers make the heart beat at a slower rate and with less force. They are now usually used only if the other types are not enough or cannot be used.

Why a doctor might recommend it

Treating high blood pressure helps prevent problems such as heart disease and stroke. Medicines are added when healthy lifestyle changes alone do not control or lower high blood pressure. Your provider also thinks about other conditions you have, such as heart or kidney disease.

How to prepare

Your provider will usually try lifestyle changes first and check your blood pressure two or more times. You may be asked to have it measured at home, at a pharmacy, or somewhere other than a doctor's office. Ask your provider which foods, drinks, vitamins, supplements, or other medicines to avoid. If you are pregnant or plan to be, talk with your provider about the medicines you take to lower your blood pressure.

What happens during it

Your provider decides with you which type of medicine is right for you. Most of the time, only a single medicine is used at first. Many people end up needing two or more medicines. Diuretics are often used with other blood pressure medicines, sometimes in one combined pill.

Recovery

Most blood pressure medicines are easy to take, but all medicines can have side effects. Most side effects are mild and may go away over time. Tell your provider as soon as possible if side effects cause you problems. Changing the dose or when you take the medicine can often help reduce side effects. Never change the amount or stop taking a medicine on your own.

Risks and side effects

Common side effects include cough, diarrhea or constipation, and dizziness or lightheadedness. Others include headache, nausea or vomiting, and a skin rash. You may also feel nervous, tired, or weak, or gain or lose weight without trying. Vitamins, supplements, foods, or alcohol may change how a drug acts in your body. Call 911 or go to the emergency room if you have trouble breathing, chest pain or discomfort lasting two minutes or more, fainting, or swelling of the face, eyes, or tongue.

Who performs it

A nutritionist or dietician, a pharmacist, and specialists for other conditions may also help. A primary care doctor or cardiologist usually prescribes the medicine.

Common questions

When do doctors recommend blood pressure medicine?

It depends on your blood pressure numbers and your other health risks. Stage 1 high blood pressure means an upper number of 130 to 139 or a lower number of 80 to 89. With stage 1, medicines are more likely if you have other diseases or risk factors. Stage 2 means an upper number of 140 or higher or a lower number of 90 or higher. With stage 2, your provider will most likely recommend medicines and lifestyle changes.

Can I stop taking blood pressure medicine when I feel fine?

No, never stop taking a medicine on your own. Always talk to your provider first.

Do I still need healthy habits while taking medicine?

Yes, keep up your healthy lifestyle changes while taking blood pressure medicines. Medicines and heart-healthy habits together can help control your blood pressure and prevent heart disease.

How does a direct primary care or concierge doctor fit in?

A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. Your doctor can help you manage your blood pressure and prevent complications. Specialists for other conditions, such as heart conditions, may also be involved.
