How to take atenolol

Atenolol is usually taken by mouth and is normally supplied as a tablet, although oral solutions are available for people who cannot take tablets. Here’s how to take your atenolol:

  • It should be taken with water and can be taken with or without food
  • The manufacturer advises that alcohol should be avoided while taking this medicine. Alcohol is known to increase blood pressure and should be reduced as part of changes to your lifestyle to control your blood pressure
  • Doses should be taken evenly apart, or close to the same time each day. There is no set time for taking the medicine. You should discuss with your doctor whether it would be better to take it in the morning (so that it works best during the day when your blood pressure is higher), or at night (so you are less likely to experience dizziness or feeling lightheaded)
  • If you forget to take a dose then take it as soon as you remember. However, if you missed your dose by more than a day then do not double-up, take the next dose as normal

How quickly will it work? – atenolol can start working to calm the heart within just one hour of taking it. And, after around two to four hours, it is almost fully absorbed into the body. It can take a week or two of regular use before the full effect of reducing your blood pressure can be achieved. If after a couple of weeks your blood pressure is still too high, your doctor may recommend increasing your dose of atenolol.

Please note – you may not feel anything but that doesn’t mean your medication is not working.

Common side effects

Common side effects of atenolol include:

  • Cold hands and feet – up to 12 in every 100 people experience this. If you feel very cold, contact your doctor

  • Diarrhoea and nausea (feeling sick) – between two and four people in every 100 may experience this
  • Orthostatic hypotension – this is when you feel dizzy or lightheaded after standing up. It can affect between two to four people per 100. If you feel like you are going to faint, you should contact your doctor. Stand slowly, climb stairs carefully, and be cautious about driving or using machines
  • Tiredness – affects between one and ten people per 100
  • Aching and tired muscles – affects between one and ten people per 100. Up to three people per 100 experience pain in their legs
