Hi, Im currently taking symbicort, ventolin and theophylline 200mg plus piriton. On Sunday I got only what I can describe as the flu, stayed in bed for 3days,my breathing wasn't to effected. Now I have a persistent cough, yellow /green phlegm and my breathing is getting worse. I have taken my meds religiously but it takes me 1 to 2hours to control my asthma and be able to just function. Tried to get a doctors appointment but couldn't , now waiting on a telephone consultation. I'm allergic to penicillin is there any other antibiotic I can take?
