Do you recommend allopurinol desensitization in gout patients who develop a rash on allopurinol therapy?  

I don't recommend desensitization for allopurinol-allergic patients. There was a time when this made sense due to the lack of a viable alternative therapy. The process is cumbersome in a private practice setting and not as simple as providing the patient with a prescription for febuxostat.Febuxostat...

Agree. Luckily, not necessary very often.
