From a prescriber’s perspective
You are 35, 45, 55. You know your job, your business, your role. But before a board presentation, job interview, wedding speech or school parent meeting, your heart pounds, your palms sweat, your face flushes. Or maybe migraines steal your weekends. Or your blood pressure monitor keeps showing numbers your GP frowns at. You want something that actually helps the physical symptoms without making you feel foggy, drowsy or dependent.
If that sounds like you, propranolol may be the medication you have been looking for.
Propranolol is a beta-blocker. It blocks adrenaline from binding to beta receptors in the heart and blood vessels. This slows a racing heart, reduces tremor and sweating, lowers blood pressure, and decreases the physical symptoms of anxiety. Unlike sedatives, propranolol does not cause dependence, mental clouding or personality changes for most people. It simply turns down the volume on your body’s “fight or flight” response.
In Australia, propranolol is TGA-approved and has been used for decades. It is available as Inderal (the original brand) and as multiple generic versions. It comes in 10 mg, 40 mg, 80 mg and 160 mg tablets.
| Indication | How propranolol helps | Typical adult dose |
|---|---|---|
| Performance or social anxiety | Reduces racing heart, sweating, tremor and blushing | 10–40 mg 30–60 minutes before event |
| Blushing | Reduces facial flushing triggered by adrenaline | 10–40 mg as needed |
| Migraine prevention | Reduces frequency and severity of migraines | 40–80 mg twice daily |
| High blood pressure | Lowers blood pressure over time | 40–80 mg twice daily |
| Essential tremor | Steadies hands and reduces visible shaking | 40–80 mg twice daily |
Blushing is not just embarrassment. It is a rush of adrenaline dilating blood vessels in your face. Propranolol helps block that adrenaline surge, so you can speak up in meetings, attend social events, go on dates, or give a presentation without your face turning bright red. Many patients tell me this one change gives them back their confidence. When you stop worrying about blushing, you can actually focus on what you want to say.
For situational anxiety, I usually start patients with 10–20 mg, increasing to 40 mg if needed. A 40 mg tablet taken 30–60 minutes before a stressful situation is the most common effective dose. The effect lasts a few hours, so there is no all-day haze. It is not an antidepressant or tranquilliser; it treats the physical symptoms of anxiety, which can break the cycle of fear and avoidance.
Inderal is the original propranolol brand available in Australia. It is widely stocked in Australian pharmacies and comes in the same strengths as generic versions. Many patients ask for Inderal by name because it has been around for decades and feels familiar. If you have a preference for the brand, your GP can specify “Inderal” on the prescription.
Propranolol 40 mg tablets are one of the most commonly prescribed strengths in Australia. They are available as brand Inderal and as generic versions. Depending on your indication and PBS listing, a pack may be subsidised. For anxiety use, a private prescription often costs around $15–$30 for 100 tablets, making it a very affordable option compared with many other anxiety or migraine medicines.

From a doctor’s point of view, generic propranolol is therapeutically equivalent to Inderal. If you have an intolerance to a particular filler or excipient, your GP can specify the brand on the script. For most people, generic propranolol is the smart, budget-friendly choice.
| Warning | What you need to know |
|---|---|
| Propranolol and diabetes type 1 – warning | Propranolol can mask the early warning signs of hypoglycaemia (low blood sugar), such as a fast heartbeat, tremor and sweating. It can also slow recovery from a hypo. If you have type 1 diabetes, propranolol is not automatically off-limits, but it must be used with careful blood glucose monitoring and a clear hypoglycaemia plan agreed with your GP or endocrinologist. |
| Propranolol and long QT syndrome – contraindicated | Propranolol is generally not recommended if you have congenital long QT syndrome or significant heart rhythm problems. It can worsen conduction and lead to dangerous arrhythmias. Always tell your doctor about any personal or family history of heart rhythm disorders, fainting or sudden cardiac death. |
Propranolol is itself a migraine preventive, but if you also use acute migraine medicines, your doctor must review the combination carefully.
| Migraine medicine | Interaction with propranolol |
|---|---|
| Triptans (sumatriptan, rizatriptan, zolmitriptan etc.) | Usually safe at standard doses, but may have additive effects on blood vessels or heart rate. Use together only under medical supervision. |
| Ergotamine-based medicines | Avoid combining; risk of dangerous blood vessel narrowing. |
| Other beta-blockers or calcium channel blockers | Additive lowering of heart rate and blood pressure; requires dose adjustment. |
Propranolol is a prescription-only medicine in Australia. You cannot buy it over the counter, but getting a script is straightforward if it is appropriate for you.
If you are over 30 and tired of physical anxiety symptoms, blushing, tremor or migraines running your life, propranolol could be a safe, effective and affordable option. Speak to your doctor today.
