What is Propranolol?
Propranolol is a tablet that is widely prescribed in the UK to treat a number of heart problems. Most commonly, propranolol is used to treat the symptoms of high blood pressure, angina, heart failure, anxiety and to prevent a second heart attack in people who have previously had one.
Propranolol is classed as a beta blocker and works by reducing the workload on the heart. It also controls the rate at which the heart beats. As a result of taking propranolol tablets, the stress on the heart is reduced and the rate at which the heart beats is also slowed down. This makes it easier for the blood to pump around your body.
Propranolol is one of two commonly prescribed beta-blockers, the other being Bisoprolol which is used mainly used to treat high blood pressure.
What is Propranolol used to treat?
This medicine is also available in a variety of strengths: 10 mg, 20 mg, 40 mg and 80 mg. Due to the severity of the conditions that propranolol beta blocker tablets are used for, this medication can only be purchased with a valid UK prescription.
You can buy Propranolol from Medicine Direct following an online consultation with one of our certified doctors, who will prescribe you this medication if they believe it to be a suitable medicine for you.

Never double dose a medication to try and make up for missing a previous dose.
