Hello Anita, Thank you for asking at HCM. I went through your history. For acute attacks of asthma, salbutamol (Asthalin) and levosalbutamol are commonly used and most effective drugs. Usually salbutamol does not cause the type of reaction you described. So personally I would think of possibility of reacting to other ingredients (propellants, preservatives, exipients) in the inhaler. So, were I treating you, I would prescribe you levosalbutamol in a different form of inhaler device manufactured by a different company. I would also suggest you to rinse your mouth after inhaling the drug and would also ask you to remain under doctor s observation for 2 hours after first dose. This might be the safest approach in my opinion. I would suggest you to discuss above information and suggestions with your doctor and decide further treatment thereafter. Hope above suggestions will be helpful to you. Should you have any further query, please feel free to ask at HCM. Wish you the best of the health. Thank you & Regards.
