Important Safety Information

See label for complete use information.

Caution: Federal (USA) law restricts this drug to use by or on the order of a licensed veterinarian.

Not for use in humans. Keep out of reach of children. In case of accidental self-injection, wash the site of injection thoroughly with clean running water. Foreign proteins such as pegbovigrastim have the potential to cause anaphylactic-type reactions.

No withdrawal period or milk discard time is required when used according to the labeling.

Do not use Imrestor to treat cows with clinical mastitis because effectiveness has not been demonstrated for this use.

Some cases of hypersensitivity-type reactions have been observed in studies outside the United States within five minutes to two hours, occurring most often after the first administration of Imrestor. Clinical signs may include elevated respiratory rate, dyspnea, urticaria, sweating, dependent edema, swollen mucous membranes, and/or hypersalivation, and, rarely, death. These reactions resolve within hours of onset with or without therapeutic intervention and have not been shown to reoccur with subsequent injections of Imrestor.

Abomasal ulcerations/erosions were observed in the Margin of Safety studies; it was concluded that these findings were not clinically relevant.
