Been diagnosed with asthma now i have flu what meds can i take that won't xounteract asthma meds?

The basics: Flu treatment is mainly supportive with fluids/nutrition and occasional use of fever meds/pain meds. None of the common OTC products like acetaminophen or ibuprofen interact poorly with the common treatment for asthma. When you post a question the more specific you are with the meds involved, the more focused we can respond with an answer.

Tamiflu: Tamiflu may be useful especially since you have asthma. Follow your asthma action plan, and if your asthma symptoms worsen, you may need a course of steroids.
