What are Atenolol tablets?

Atenolol tablets are a medication that belong to a group called beta-blockers, used to treat high blood pressure and heart problems such as uneven heartbeat and angina. Atenolol tablets slow down your heart rate which makes it easier for your heart to pump blood around the body and therefore lowering blood pressure.

Some people may find that Atenolol tablets can cause slight dizziness, if this is the case take Atenolol tablets before bed. Always complete the full course of treatment you have been prescribed as suddenly stopping the medication can cause your condition to worsen.

High blood pressure rarely has noticeable symptoms, and if left untreated greatly increases the risk of stroke and heart attack. High blood pressure occurs for a variety of reasons including genetic predispositions, weight and old age. Medication such as Atenolol tablets may be prescribed to help reduce high blood pressure and therefore reduce the risk of heart attack or stroke.

Atenolol tablets should be taken daily with water, there are a variety of dosages but the standard starting dose is between 50-100mg a day. This may be different depending on your circumstances, it’s important to always follow what your doctor has prescribed. Atenolol tablets will be most effective in combination with a healthy diet and exercise as this will naturally reduce your blood pressure.

If Atenolol tablets are not effective there are other medications for high blood pressure. Speak to your doctor or pharmacist to find the best solution for you.
