Thank You. I Have A Friend Who Takes Cimzia For

Thank you. I have a friend who takes Cimzia for Psoriatic Arthritis. She also drinks far too much alcohol. She is petite, 5'1" and has lost almost 25 lbs in less than a year. She tells me that her doctor is not concerned about her weight loss. She has no appetite....I am so concerned about her, but she looks awful and cites that weight loss is a side effect of taking Cimzia.....
Please tell me if I should be concerned. Thank you......
