I’ve been prescribed prochlorperazine by my Gp for vertigo.. I’ve never had it before and have no idea what the route cause of me having this is..I’m fine sat in a certain position and not moving however the second I stand up the room is spinning and I vomit.. it’s horrible I’ve had two doses so far and not really seen Any difference I’ve been sick again since taking the second dose.. I don’t expect miracles but I did read it takes 30-60 mins to take effect.. has it been longer for anyone else who’s been prescribed this?
