Cardiovascular

Hypotension following oral PA administration is rare. Hypotension and serious disturbances of cardiorhythm such as ventricular asystole or fibrillation are more common after. Second degree heart block has been reported in 2 of almost 500 patients taking PA orally.

Multisystem

A lupus erythematosus-like syndrome of arthralgia, pleural or abdominal pain, and some-times arthritis, pleural effusion, pericarditis, fever, chills, myalgia, and possibly related hematologic or skin lesions is fairly common after prolonged PA administration, perhaps more often in patients who are slow acetylators. While some series have reported less than 1 in 500, others have reported the syndrome in up to 30 percent of patients on long term oral PA therapy. If discontinuation of PA does not reverse the lupoid symptoms, corticosteroid treatment may be effective.

Hematologic

Neutropenia, thrombocytopenia, or hemolytic anemia may rarely be encountered. Agranulocytosis has occurred after repeated use of PA, and deaths have been reported.

Skin

Angioneurotic edema, urticaria, pruritus, flushing, and maculopapular rash have also occurred occasionally.

Gastrointestinal

Anorexia, nausea, vomiting, abdominal pain, bitter taste, or diarrhea may occur in 3 to 4 percent of patients taking oral procainamide.

Elevated Liver Enzymes

Elevations of transaminase with and without elevations of alkaline phosphatase and bilirubin have been reported. Some patients have had clinical symptoms (e.g., malaise, right upper quadrant pain). Deaths from liver failure have been reported.

Nervous System

Dizziness or giddiness, weakness, mental depression, and psychosis with hallucinations have been reported occasionally.
