Started Ibrutinib 2 weeks ago and developed a sore throat with fever last Saturday. Seen by Triage as per the protocol - sent home with 4 days of antibiotics, just in case, although there was no evidence of bacterial or viral infection. Temp rose overnight to 38.9, tremendous difficulty in swallowing, due to swollen throat. Temp has now subsided but my throat is still horrendously sore and swallowing extremely painful - to the point where I am not really eating, although drinking is okay, and actually helps. I'm seeing my consultant tomorrow, but my question is this: do Ibrutinib side effects get better??
