Bisoprolol

What is bisoprolol used for?

Bisoprolol is a beta-blocker, a type of medicine that affects the heart and circulation (blood flow through arteries and veins)[1].  

Bisoprolol is used to treat[1]:  

• High blood pressure (hypertension) 

• Heart failure 

• Angina (chest pain) 

• Atrial fibrillation (to help control heart rhythm and reduce the risk of complications) 

How does bisoprolol work?

Bisoprolol is a beta-blocker and works by blocking receptors in the heart[1]. This causes the heart rate to slow down, reduces the force of each heartbeat, and lowers blood pressure. It also helps the heart pump more efficiently. 

This reduces the heart’s workload and oxygen demand, which is especially helpful in heart failure and angina[1]. 

Who can take bisoprolol?

Most adults can take bisoprolol, but it may not be suitable for people who[1]: 

• Have asthma or other breathing disorders 

• Have very low blood pressure 

• Have severe circulation problems 

• Have slow heart rate or heart block 

• Are pregnant or breastfeeding (only under medical advice) 

• Have diabetes, liver, or kidney problems 

Always consult a doctor or pharmacist before starting bisoprolol, and follow the instructions in the Patient Information Leaflet[2]. 

How do you take bisoprolol?

Bisoprolol is normally taken once a day, preferably in the morning. Swallow the tablets whole with a drink of water with or without food. Try to take it at the same time each day[1]. 

What is the typical dosage of bisoprolol?

Dosages depend on why you are being given bisoprolol. For high blood pressure or angina, the starting dose will be 5mg to 10mg once a day. The maximum dose being 20mg daily. For heart failure, the starting dose is usually 1.25mg daily, and increased gradually over weeks up to 10mg daily[1].  

Taking bisoprolol at the same time each day helps maintain steady levels in your body. 

Your doctor or pharmacist will adjust the dose based on your response and condition. 

Can you stop taking bisoprolol?

Do not stop suddenly unless advised by your doctor or pharmacist. Stopping abruptly can cause your blood pressure to rise and increase your risk of a heart attack or stroke. You should take your bisoprolol even if you feel well[1]. 

What do you do if you take too much bisoprolol?

Taking too much bisoprolol can cause your heart rate to slow down and make it difficult to breathe. It can also make you feel dizzy or faint[1]. 

You should call 111 for advice if you’ve taken more than your regular dose of bisoprolol. If you suspect an overdose, call 999 or go to A&E immediately, as it can be life-threatening[1]. 

What do you do if you forget to take bisoprolol?

If you miss a dose and remember within 12 hours of your usual dose time, take it as soon as possible. If it’s closer to your next dose, skip the missed dose. and continue with your regular schedule. Never take 2 doses at the same time[1].
