Hello.
Thank you for asking at HCM.
I went through your daughter's history and understand your concern about the medication which is not available at your place in Kolkata.
Combitide Starhaler 125/25 contains two drugs -
Fluticasone 125 mcg and
Salmeterol 25 mcg
Combitide Starhaler 250 contains - Fluticasone 250 mcg and Salmeterol 25 mcg
Combitide Starhaler 125/25 2 puffs twice will give her total Flutocasone 500 mcg and Salmeterol 100 mcg in a day.
However, Combitide Starhaler 1 puff twice a day will give her total Fluticasone 500 mcg and Salmeterol 50 mcg in a day.
Thus, she will not get dose of Salmeterol recommended by your doctor if she uses Combitide Starhaler 250.
There are other similar inhalers containing Fluticasone 125 and Salmeterol 25 which may be available in Kolkata, but they may be manufactured by other companies.
So, personally I would not suggest you to use Combitide Starhaler 250 in place of Combitide Starhaler 125/25 unless her treating doctor allows you. It will be best option for you to ask her doctor regarding this.
Online purchasing her prescribed inhaler may be a good option if it is not available in your city.
If it is not possible to contact her doctor in Vellore or to wait till delivery (for online shopping), in my opinion, second best option may be to give her inhaler with similar contents manufactured by other company till your next visit to Vellore.
Hope above information will be helpful to you.
Should you have any further query, please feel free to ask at HCM.
Wish your daughter the best of the health.
Thank you & Regards.
