Blood pressure medication is one of the most important treatments after a stroke. High blood pressure is the leading risk factor for both first and recurrent strokes, even if you have never previously been diagnosed with hypertension. These medications lower blood pressure, reduce strain on your arteries and significantly reduce your risk of another stroke or heart attack. Learn why blood pressure medication is prescribed after a stroke, the different types available, possible side effects and why taking it as prescribed is essential for protecting your recovery.

After your stroke...

You leave hospital with several new medications.

One of them is for your blood pressure.

Perhaps you've never had high blood pressure.

Maybe your blood pressure seems normal now.

You begin wondering...

"Why do I need blood pressure medication after my stroke?"

Or perhaps...

You're worried about taking tablets for the rest of your life.

The good news is...

Blood pressure medication is one of the most effective ways to reduce your risk of another stroke.

The Good News

For many stroke survivors, controlling blood pressure is the single most important step in preventing another stroke.

Even small reductions in blood pressure can significantly lower your future risk.

When combined with healthy lifestyle choices and other prescribed medications, blood pressure medication helps protect your brain, heart and blood vessels for years to come.

✦ ✦ ✦

What Is Blood Pressure Medication?

Blood pressure medication is a group of medicines designed to lower the pressure inside your arteries.

Lower blood pressure means:

✓ Less strain on blood vessel walls.

✓ Reduced damage to the arteries.

✓ Lower risk of blood clots forming.

✓ Lower risk of blood vessels bursting.

✓ Better long-term protection for your brain and heart.

There are several different types of blood pressure medication, and many people take more than one because they work in different ways.

✦ ✦ ✦

Why Is Blood Pressure Medication Prescribed After a Stroke?

High blood pressure is the biggest modifiable risk factor for stroke.

Over time, high pressure damages the lining of blood vessels, making them more likely to become blocked or rupture.

Blood pressure medication helps reduce the risk of another stroke by:

✓ Lowering blood pressure.

✓ Reducing strain on blood vessels.

✓ Protecting the arteries from further damage.

✓ Reducing the risk of blood clots.

✓ Lowering the chance of bleeding inside the brain.

Together, these effects greatly reduce the risk of future strokes.

✦ ✦ ✦

Do I Need Blood Pressure Medication If My Blood Pressure Is Normal?

Possibly.

Many people are surprised to learn they are prescribed blood pressure medication even when their readings appear normal.

That's because your doctor is treating your future stroke risk—not just today's blood pressure reading.

Blood pressure naturally changes throughout the day, and lower long-term blood pressure provides greater protection after a stroke.

Your healthcare professional will decide the blood pressure target that is safest and most appropriate for you.

Common Types of Blood Pressure Medication

Several different medicines may be used after a stroke.

ACE Inhibitors

Examples include:

✓ Ramipril.

✓ Perindopril.

✓ Lisinopril.

These relax blood vessels, allowing blood to flow more easily.

Angiotensin II Receptor Blockers (ARBs)

Examples include:

✓ Candesartan.

✓ Losartan.

✓ Irbesartan.

These work in a similar way to ACE inhibitors but are less likely to cause a persistent cough.

Calcium Channel Blockers

Examples include:

✓ Amlodipine.

✓ Felodipine.

These relax the muscles in the artery walls, helping lower blood pressure.

Diuretics (Water Tablets)

Examples include:

✓ Indapamide.

✓ Bendroflumethiazide.

These help remove excess salt and water from the body.

Beta Blockers

Examples include:

✓ Bisoprolol.

✓ Atenolol.

These slow the heart rate and reduce blood pressure and may also be prescribed for certain heart conditions.

✦ ✦ ✦

Will I Need More Than One Medication?

Possibly.

Many stroke survivors take two or more blood pressure medications.

Different medications lower blood pressure in different ways, and using lower doses of several medicines often works better than taking a high dose of one.

Your medication may also change over time depending on how your blood pressure responds.

✦ ✦ ✦

Benefits of Blood Pressure Medication

Taking your medication as prescribed can:

✓ Reduce the risk of another stroke.

✓ Lower the risk of heart attack.

✓ Protect your arteries.

✓ Reduce damage to blood vessels.

✓ Improve long-term cardiovascular health.

The greatest benefit comes from taking your medication consistently over many years.

✦ ✦ ✦

Possible Side Effects

Most people tolerate blood pressure medication very well.

Possible side effects include:

✓ Dizziness.

✓ Light-headedness.

✓ Tiredness.

✓ Headache.

✓ Swollen ankles (with some medications).

✓ Dry cough (ACE inhibitors).

✓ Frequent urination (diuretics).

Many side effects improve as your body adjusts during the first few weeks.

Never stop taking your medication without speaking to your healthcare professional.

Rare but Serious Side Effects

Although uncommon, seek medical advice promptly if you develop:

✓ Severe dizziness causing fainting.
