Side effects of beta-blockers 

Most people taking beta-blockers have either no or very mild side effects.

Although there are often many side effects listed on the patient information leaflets that come with the medicine, they usually include all of the symptoms that have been reported by people taking beta-blockers – some of which may have occurred naturally.

Contact your GP if you're experiencing symptoms that affect your everyday life. They can discuss with you whether the symptoms are a result of the medication, and what to do.

Symptoms that are commonly reported both by people taking beta-blockers and those taking a placebo (dummy medication) include:

  • dizziness
  • tiredness
  • blurred vision
  • cold hands and feet
  • slow heartbeat
  • diarrhoea and nausea

Less common symptoms include:


Beta-blockers are unlikely to affect your ability to drive safely. However, don't drive if you feel dizzy, tired or if your vision is affected.

Yellow Card Scheme

The Yellow Card Scheme allows you to report symptoms from any type of medicine you're taking.

It's run by the Medicines and Healthcare products Regulatory Agency (MHRA) – the medicines safety watchdog.
