What are Propranolol tablets?
Propranolol tablets are widely prescribed in the UK to treat a number of heart problems. Most commonly, propranolol can be used to treat high blood pressure, angina, heart failure, anxiety and to prevent a second heart attack in people who have previously had one.
Propranolol tablets are also available under a number of different brand names such as:
- Half Beta-prograne
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 tablets are available in a number of different doses. Propranolol 40mg is the strongest dose of propranolol available and is usually the starting dose when treating conditions related to anxiety. The other available dose is propranolol 10mg tablets.
If you are new to beta blockers and would like to understand more about how they work and what conditions they treat, you can take a look at our guide to beta blockers.
What are Propranolol 10mg & 40mg tablets used to treat?
Propranolol is a drug that can be used for a number of treatments, the most common of these being high blood pressure, angina, heart failure, heart attacks, migraines and glaucoma, however it is most effective when treating anxiety.
Propranolol tablets and other beta blockers should not be used as a first line treatment option for uncomplicated hypertension (high blood pressure) due to their inability at reducing the risk of a stroke and coronary artery disease when compared to other alternatives such as Calcium Channel Blockers and Thiazide Diuretics.
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.
Propranolol 40mg is usually prescribed for a number of conditions when other treatments or the lower dose of Propranolol 10mg have failed to relieve symptoms.
How does Propranolol work?
Propranolol will not cure underlying anxiety triggers; however, it will help your body cope with some of the physical symptoms of anxiety, particularly an increased heart rate and blood pressure.
Propranolol can help control and regulate the rate at which the heart beats, this also eases the pressure on the heart as it is able to pump blood around the body at a more stable rate.
Propranolol blocks the body’s natural adrenaline/stress messages that are sent to the heart in times of distress. When those adrenaline and stress messages are received by the heart, it beats faster and harder.
By stopping those messages being received by the heart, propranolol can ensure that the heart is relaxed and beating at a normal rate. An increased heart rate is one of the first signs of an anxiety attack, propranolol helps to reduce this physical symptom.
How to take propranolol tablets
This medication can be taken with or without food as it does not upset your stomach. However, you should try to take it at the same time every day.
The tablets should be swallowed whole with a drink of water. If you have difficulty swallowing tablets, certain brands of Propranolol have a score line which lets you break them in half. Read the information leaflet that will come with your medicine to make sure you can do this with your tablets.
