[/INST] Hello.Thank you for asking at HCM.Seroflow contains a drug Salmeterol and Asthalin contains drug salbutamol. Both salmeterol and salbutamol can cause increased heart beat and tremors.I would suggest you to consult your doctor if dose reduction or change to another medicines is possible. Also, personally I feel Seroflow 250 inhaler 8 times a day is a higher dose. Hope this will be helpful to you.Wish you the best of the health.Regards. </s>
