I am taking the above for GCA and have had two infusions and two injections. My latest bloods are great re CRP and ESR but I now have high cholesterol - 7 - not sure how bad 7 is and whether the drug has caused it. I have never had high cholesterol before. Also I have a bad cough, which I think I caught from a friend staying with me. I seem fine with the cough but wonder if I should be taking antibiotics because of my compromised immune system, As usual I cannot get an appointment with my GP and I put a call into the consultant but havn't heard anything yet. I had been feeling so very much better on the Tocilizumab.
