Use
Phenylbutazone, a pyrazolone derivative with anti-inflammatory,
analgesic and antipyretic activity, was introduced in 1949 for the treatment of
rheumatic disorders. Its use was subsequently associated with serious and
sometimes fatal adverse reactions, notably cases of aplastic anaemia and
agranulocytosis. Many national drug regulatory authorities consider that more
recently introduced drugs offer a safer alternative for most, if not all, patients
requiring anti-inflammatory agents. Phenylbutazone has thus been either
withdrawn at the national level or retained with rigorously restricted indications for
patients unresponsive to other therapy. These restrictions also apply, in general, to
combination products containing phenylbutazone.
