Suggest Treatment For Allergic Reaction To Face Product

I am taking prednisone for a reaction to a product I purchased by the name of Optrex. As a result of spraying the product on my face I have had a reaction that has caused my face to itch and swell I have recently come out of hospital with a punctured lung and I was on pain killers which I have now finished What I would like to know is does Prednisone make you feel unwell???
