Postural Orthostatic Tachycardia Syndrome (POTS) is a condition that’s gaining more recognition in Australia. It affects the autonomic nervous system, leading to a rapid increase in heart rate when standing up, often accompanied by dizziness, fatigue and brain fog. For some people living with POTS, beta blockers are prescribed as part of their treatment plan.
What is POTS?
POTS is a form of dysautonomia, meaning it’s linked to problems with how the nervous system regulates blood flow and heart rate. A person with POTS may experience:
- A sudden racing heartbeat on standing
- Lightheadedness or fainting
- Tiredness and difficulty concentrating
- Exercise intolerance
Although POTS can affect anyone, research shows it’s more commonly diagnosed in younger women. In Australia, increasing awareness among GPs and specialists is helping more people receive a timely diagnosis.
How Beta Blockers Help
Beta blockers are a group of medications that reduce the effect of adrenaline on the heart. By doing so, they can slow down the heart rate and make symptoms of POTS more manageable.
Common beta blockers prescribed in Australia include propranolol and metoprolol. They may be particularly helpful for people whose main symptom is a very rapid heart rate on standing. However, beta blockers are not a cure for POTS—they are usually just one part of a broader management plan.
Additional Ways to Treat POTS
Managing POTS often requires a combination of strategies. These may include:
- Increasing salt and fluid intake to boost blood volume
- Wearing compression stockings to reduce pooling of blood in the legs
- Graded exercise programs, often supervised by a physiotherapist
- Other medications, if symptoms aren’t controlled with beta blockers alone
Possible Side Effects of Beta Blockers
While Beta blockers can be useful, they don’t suit everyone with POTS. Possible side effects include:
- Fatigue or low energy
- Cold hands and feet
- Low blood pressure
- Sleep disturbances
Because POTS symptoms vary widely, some people notice improvements with beta blockers, while others may find little benefit or even worsening of fatigue. It’s important that medication is prescribed and monitored by a doctor who understands the condition.
Talking to Your Doctor in Australia
If you suspect you have POTS, or you’ve already been diagnosed, the next step is to discuss treatment options with your GP. In many cases, a referral to a cardiologist or neurologist with experience in autonomic disorders is needed. Medicare covers many aspects of assessment and management, though waiting times may vary depending on where you live.
Living Well with POTS
While POTS can be challenging, many Australians learn to manage their symptoms over time. Support groups, both online and in person, can be helpful for sharing strategies and reducing isolation. Day-to-day adjustments—such as pacing activities, staying hydrated and planning rest breaks—can make a big difference.
Conclusion
For Australians living with POTS, beta blockers can play a valuable role in easing symptoms, particularly fast heart rate. However, they’re usually just one part of a tailored treatment plan that may also involve lifestyle changes, physiotherapy and other medications. Always seek professional medical advice before starting or changing any treatment. With the right support, it’s possible to improve quality of life and better manage this condition.
