I have had a head cold/ sore throat all week and generally just sickish! I was just wondering do I need an anti biotic because I am on Plaquinil Methotrexate & Humira, I mean is it necessary or could I fight it. I have used usual vit c paracetamol etc, still not well. Also, interestingly the chemist said not to take echinaecea, nor rec with these med as boosts immune system and they supress same! Did'nt take my 20mg mtx this week as usually they say to stop if suspect infection? Any thoughts?
