What are beta-blockers?

Beta-blockers are drugs traditionally prescribed to people with heart conditions. Beta-blockers slow down the heart and lower blood pressure. Beta-blockers are sometimes prescribed to people with autism spectrum disorder (ASD) to reduce feelings of anxiety.

Some commonly prescribed beta-blockers for ASD are Tenormin (atenolol) and Inderal (propranolol).

Who are beta-blockers for?

Beta-blockers are used for people with autism spectrum disorder (ASD) who show high levels of aggression and anxiety. If people have asthma as well as ASD, they should use beta-blockers cautiously because these drugs can narrow the airways.

What are beta-blockers used for?

Beta-blockers are used to treat behaviour like hyperactivity, impulsivity, aggression, anxiety, self-harm and obsessive-compulsive behaviour.

Where do beta-blockers come from?

Beta-blockers were first trialled with people with autism spectrum disorder (ASD) in 1987. Researchers found that they reduced aggression and improved social skills in a small group of adult participants.

What is the idea behind using beta-blockers?

Researchers believe that people with autism spectrum disorder (ASD) might experience high levels of anxiety or stress brought on by changes in their environment. This constant state of inner tension might lead to more extreme behaviour, including aggression.

Beta-blockers decrease the body’s ‘fight or flight’ response – a natural reaction to stress, anxiety or frustration. The idea is that by reducing the ‘fight or flight’ response, these drugs decrease the feelings of tension that might lead to aggressive behaviour.

Like most medical interventions, beta-blockers do not (and are not supposed to) improve behavioural and social difficulties of people with ASD. Instead, they’re meant to reduce other symptoms associated with ASD.

What does the use of beta-blockers involve?

This therapy involves taking oral medication on a daily basis. The specific medication and dosage depends on each child’s symptoms.

A specialist medical practitioner like a psychiatrist should monitor the person taking the medication. The person needs to have regular appointments with the specialist.

Cost considerations

The cost of the medication varies depending on the medication brand, dosage, whether the consumer holds a concession card, and whether the medication is subsidised by the Australian Government through the Pharmaceutical Benefits Scheme (PBS).
