Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. You must be on biological drugs for treating Rheumatoid arthritis (RA), which needs to stop while you are ill. You can resume the medication once a cough, sneeze, mucus production, and fever (if any) subsides. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Lekshmi Rita Venugopal
