Can intake of Tamiflu worsen asthma and cough-related issues?
Patient: My 12 yr old son has been having problems with his asthma.  We are following his yellow zone protocols and he just finished up with an oral steroid for 5 days.  He is still coughing a lot and his doctor recommended we up his maintance inhaler yesterday.  My daughter was diagnosed with influenza A so he was put on Tamiflu as a precautionary measure.  I just gave him the first dose at 7 and it seems like his cough/asthma issues have gotten worse since.  Could this be a reaction to the Tamiflu?  He has no other symptoms of a run Doctor: Cough is not a known side effect of taking Tamiflu.The cough could be due to the influenza. I would recommend an over the counter anti tussive like Dextrometharphan. Also water vapor inhalation might be helpful.Hope this answers your query. Thank you
