Hello. I have recently moved to Chengdu in the shuangliu district. I am asmatic and usually would use a ventolin (blue) reliever inhaler and would us a clenil modulite (brown) preventer inhaler. I have managed to find a ventolin inhaler on tao bao but cant find a clenil modulite inhaler. I have been to the local chemist and they dont even have preventers. Any help on how i can get these inhalers would be greatly appreciated.
