So I'm a hypochondriac anyway so this may just be me being paranoid but I have a cold right now that's decided to settled on my chest. I've had to take my salbutamol twice in 3 hours and after this second time it's already wearing off. I read the patient leaflet and it says if you take too much and experience these symtpms (rapid heartbeat, shakes, face flushing) then to see your doctor ASAP. Well being as I technically took an overdose (didn't leave a 4 hour gap) and I suffered these symptoms which I actually always thought were normal salbutamol side effects, I always get them, I am now freaked out!! So basically my question is, are those side effects anything to be alarmed about and am I really not safe if I need to take another dose before my four hours is up because it is incredibly uncomfortable to lie flat right now.
