hi I have recently joined this page and thought I would share my experience with you in a hope it may help someone. I am 52 and have suffered with asthma (brittle asthma) for most of my life. I have been steroid dependant for many year but thanks to now having xolair injections I'm only taking 5mg and 10mg on alternative days. I still use my ventolin a fair bit but no where near as much as I did. If anyone is offered the jabs I would highly recommend trying them. I was referred to Glenfields in Leicester they're wonderful! However I am now having mine at my local hospital, three injections every four weeks. If you have allergic asthma enquire if your suitable to try them.
