I was prescribed propranolol for motorway anxiety and took 40mg tablet 1 hour before a journey. i felt very 'other worldly' and spaced out and it didn't work for me, should i increase the dosage?

Discuss: with the prescriber side effect of propanolo includes bradycardia which could be symptomatic

Best to ask provider: Try to get advice from the prescriber. If impossible, you can probably safely double that dose, but don't do more than that w/o medical approval for your specific body and conditions. These drugs are powerful agents and that's why only a select group of licensed authorized professional can prescribe them or modify the specifics. Take your well-being seriously - you deserve to be treated w/ care!
