Big Problem
Hello Doctor,
I have been prescribed Inderal 20 mg (propranolol) for anxiety-related fast heart rate in social situations. I mainly experience increased heart rate without other symptoms.
I have an event (wedding) coming up, and I wanted to ask:
- Can I take one dose before the event and, if needed, take another dose later the same day after the effect wears off?
- What should be the safe time gap between two doses?
- What is the maximum safe dose I can take in a day for this purpose?
Thank you.

Propranolol can be helpful for situational anxiety like this, but dosing and repeat use on the same day should be individualized based on your baseline heart rate, blood pressure, and any other medical conditions. Taking an extra dose or adjusting timing without guidance can sometimes lead to side effects like low blood pressure, dizziness, or excessive slowing of heart rate.
It would be best to check with your prescribing doctor before the event so they can guide you on whether a repeat dose is appropriate, the safe interval, and your maximum dose for the day based on your profile.

Hii...Using Propranolol (Inderal) for performance or social anxiety–related fast heart rate is appropriate. It helps control physical symptoms like palpitations but does not directly treat anxiety thoughts.
Next Steps
You can take a single dose 30–60 minutes before the event
If required, a second dose may be taken later the same day, provided there are no side effects
Health Tips
Usual situational dose: 10–40 mg before event
Minimum gap: ~6–8 hours between doses
Maximum (for such use): generally not exceeding 80mg, but depending upon the patient. It might cause low BP in some people
First try the medication on a non-event day to see how your body responds
Avoid if you have asthma, low BP, or very low heart rate
Do not combine with alcohol (may increase dizziness)
Continue breathing/relaxation techniques along with medication
