Flying tomorrow- v. Scared. Daily I take 50mg Pregabalin and 30 mg mirtazapine. For the flight I have Propanalol and previously prescribed 5mg diazepam. I wondered if anyone knew if these were OK to take if I need them both on the flight (take pregabalin/mirtazapine at night and would need the diazepam and Propanalol during the day). Any advice would be great! Don't want to worry about drug interaction as well as the flight.
