Early diagnosis and treatment can control your blood pressure before it harms your health. You will have your blood pressure measured several times before your doctor will decide to prescribe any anti-hypertensive drugs. This is to make sure your blood pressure remains consistently high and is not just going up as a result of visiting the surgery. The aim of blood-pressure treatment is to reduce diastolic BP to below 85 mmHg and/or systolic BP to below 140 mmHg (thresholds may be different in some groups of people such as the very elderly). Sometimes two or even three different types of drug are needed to achieve this goal.

The aim of treatment is to lower your blood pressure gradually. Your doctor will start you off on a low dose of tablets to see how your blood pressure responds. If this is not enough, your dose may be increased, other drugs may be added in, or your medication may be completely changed. In some cases, more than one drug may be needed to achieve an acceptable BP. It may seem annoying to have to take one, two or even three different kinds of drugs when you feel perfectly well. But by prescribing treatment to keep your blood pressure within normal limits, your doctor is helping you to avoid the complications of uncontrolled hypertension – heart attack, stroke, peripheral vascular disease, kidney failure and even blindness.

It is important to take your blood pressure tablets regularly as prescribed. Some tablets only need only to be taken once a day, but others may need to be taken two or more times daily. This depends on how long each dose of medicine works in your body, and on how bad your blood pressure is.

When most forms of anti-hypertensive treatment are stopped, blood pressure only climbs up only slowly over several days or even weeks. With some forms of treatment, however, a rebound effect can occur so your blood pressure shoots back up.

Don’t stop taking your blood pressure treatment without first consulting your doctor. If you notice something that may be a side-effect, such as a rash, dizziness or sexual problems, always tell your doctor immediately so your dose can be altered or your treatment changed to one that suits you better.

Research shows that controlling hypertension can:

lower the risk of stroke by 35 per cent

reduce the risk of heart complications by 20 per cent

reduce overall risk of death at any age by 15 per cent.
