OVERDOSE

Massive overdosing or acute poisoning by ZYLOPRIM has not been reported.

In mice, the 50% lethal dose (LD50) is 160 mg/kg given intraperitoneally (IP) with deaths delayed up to 5 days and 700 mg/kg orally (PO) (approximately 140 times the usual human dose) with deaths delayed up to 3 days. In rats, the acute LD50 is 750 mg/kg IP and 6000 mg/kg PO (approximately 1200 times the human dose).

In the management of overdosage there is no specific antidote for ZYLOPRIM. There has been no clinical experience in the management of a patient who has taken massive amounts of ZYLOPRIM.

Both ZYLOPRIM and oxipurinol are dialyzable; however, the usefulness of hemodialysis or peritoneal dialysis in the management of an overdose of ZYLOPRIM is unknown.

CONTRAINDICATIONS

Patients who have developed a severe reaction to ZYLOPRIM should not be restarted on the drug.
