Company Announcement

FOR IMMEDIATE RELEASE – March 12, 2024 – DUBLIN, Ireland – Endo International plc announced today that one of its operating companies, Par Pharmaceutical, Inc. (Par), is voluntarily recalling one lot of Treprostinil Injection 20mg/20mL (1mg/mL) to the consumer level. The product is being recalled due to the potential for the presence of silicone particulates in the product solution.

Administration of an injectable product that contains particulate matter may result in local irritation or swelling in response to the foreign material. If the particulate matter reaches the blood vessels it can travel to various organs and block blood vessels in the heart, lungs or brain which can cause stroke and even lead to death. To date, Par has not received any reports of adverse events related to this recall.

The product is a prostacyclin vasodilator indicated for the treatment of pulmonary arterial hypertension to diminish symptoms associated with exercise and for patients who require transition from epoprostenol to reduce the rate of clinical deterioration.
