Erythromycin ethylsuccinate: The most frequent side effects of oral erythromycin preparations are gastrointestinal and are dose-related. They include nausea, vomiting, abdominal pain, diarrhea and anorexia. Symptoms of hepatic dysfunction and/or abnormal liver-function test results may occur (see WARNINGS section). Pseudomembranous colitis has been rarely reported in association with erythromycin therapy.
There have been isolated reports of reversible hearing loss occurring chiefly in patients with renal insufficiency and in patients receiving high doses of erythromycin.
Sulfisoxazole acetyl: Included in the listing that follows are adverse reactions that have been reported with other sulfonamide products: pharmacologic similarities require that each of the reactions be considered with Pediazole (erythromycin and sulfisoxazole) administration.
Allergic/Dermatologic: Anaphylaxis, erythema multiforme (Stevens-Johnson syndrome), toxic epidermal necrolysis (Lyell's syndrome), exfoliative dermatitis, angioedema, arteritis, vasculitis, allergic myocarditis, serum sickness, rash, urticaria, pruritus, photosensitivity, and conjunctival and scleral injection. In addition, periarteritis nodosa and systemic lupus erythematosus have been reported. (See WARNINGS.)
Endocrine: The sulfonamides bear certain chemical similarities to some goitrogens, diuretics (acetazolamide and the thiazides) and oral hypoglycemic agents. Cross-sensitivity may exist with these agents. Developments of goiter, diuresis, and hypoglycemia have occurred rarely in patients receiving sulfonamides.
Gastrointestinal: Hepatitis, hepatocellular necrosis, jaundice, pseudomembranous colitis, nausea, emesis, anorexia, abdominal pain, diarrhea, gastrointestinal hemorrhage, melena, flatulence, glossitis, stomatitis, salivary gland enlargement, and pancreatitis. Onset of pseudomembranous colitis symptoms may occur during or after treatment with sulfisoxazole, a component of Pediazole. (See WARNINGS.)
The sulfisoxazole acetyl component of Pediazole (erythromycin and sulfisoxazole) has been reported to cause increased elevation of liver-associated enzymes in patients with hepatitis.
The frequency of renal complications, commonly associated with some sulfonamides, is lower in patients receiving the more soluble sulfonamides such as sulfisoxazole.
Hematologic: Leukopenia, agranulocytosis, aplastic anemia, thrombocytopenia, purpura, hemolytic anemia, anemia, eosinophilia, clotting disorders including hypoprothrombinemia and hypofibrinogenemia, sulfhemoglobinemia, and methemoglobinemia.
Vascular: Angioedema, arteritis, and vasculitis.
