When monitoring a client taking allopurinol to treat gout, a nurse should be vigilant for manifestations of hypersensitivity syndrome. One of the key manifestations of hypersensitivity syndrome associated with allopurinol is a fever and rash. This can indicate an allergic reaction to the medication.
