hello and welcome to HCM
asthalin is salbutamol
a short acting beta 2 agonist, it is a bronchodilator
and very effect for acute asthma attacks. for better control of asthma a physician uses step up therapy. i.e if you symptoms are not controlled with asthalin, seroflo is introduced. seroflo is a combination of salmeterol
( long acting beta 2 agonist and a steroid) it is generally a very safe drug but as with all drugs side effects can occur in some people. these can be avoided by using the drug in prescribed dose and by washing mouth after its use. possible side effects include allergy to any component of the drug, headache, muscle cramps
, pains in joints, skin rash or trembling, increase in pulse rate or irregular heartbeat, particularly those taking higher doses.
hope this helps
