Allergies to penicillin have been observed but these are very rare. If such signs of sensitivity occur, stop medication and call your veterinarian. In some instances, particularly if respiratory distress is severe, immediate injection of epinephrine or antihistamine may be necessary. Potentially fatal reactions associated with the administration of procaine penicillin in horses have been observed. In sucking and fattening pigs, administration of products containing procaine penicillin may cause transient pyrexia, vomiting shivering, listlessness and incoordination. In pregnant sows and gilts, a vulval discharge which could be associated with abortion has been reported.
