Ive been on methotrexate for a month now. a week later I developed an upper respiratory infection with a cough and heavy phlegm. antibiotics cured the infection and now I have a dry cough. Im taking the methotrexate for lupus Is the dry cough from that and if so should I be concerned
You need to be particular as Methotrexate can lead to fibrosis of lung and can lead to cough and fibrosis.
