I wonder what were your in-law’s febuxostat dosage and serum uric acid. I’m not aware of any study taking this into account when looking at side-effects in comparison to allopurinol so it’s not clear allopurinol is inherently less dangerous. Certainly febuxostat is often used in a reckless way.
Also, were there any warning signs such as chest pain or strange test results?
