SIDE EFFECTS
The following adverse reactions associated with the use of SEPTRA or trimethoprim-sulfamethoxazole were identified in clinical studies, postmarketing or published reports. Because some of these reactions were reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
The most common adverse effects are gastrointestinal disturbances (nausea, vomiting, anorexia) and allergic skin reactions (such as rash and urticaria). Fatalities associated with the administration of sulfonamides have occurred due to severe cutaneous adverse reactions (SCARs), including Stevens-Johnson syndrome, toxic epidermal necrolysis, and drug reaction with eosinophilia and systemic symptoms(DRESS), fulminant hepatic necrosis, agranulocytosis, aplastic anemia, other blood dyscrasias, acute and delayed lung injury, anaphylaxis, and circulatory shock (see WARNINGS).
Hematologic
Agranulocytosis, aplastic anemia, thrombocytopenia, leukopenia, neutropenia, hemolytic anemia, megaloblastic anemia, hypoprothrombinemia, methemoglobinemia, eosinophilia, thrombotic thrombocytopenic purpura, idiopathic thrombocytopenic purpura.
Allergic
Stevens-Johnson syndrome, toxic epidermal necrolysis, DRESS, acute generalized exanthematous pustulosis (AGEP), acute febrile neutrophilic dermatosis (AFND), anaphylaxis, allergic myocarditis, erythema multiforme, exfoliative dermatitis, angioedema, drug fever, chills, Henoch-Schonlein purpura, serum sickness-like syndrome, generalized allergic reactions, generalized skin eruptions, photosensitivity, conjunctival and scleral injection, pruritus, urticaria, and rash. In addition, periarteritis nodosa and systemic lupuse rythematosus have been reported.
Gastrointestinal
Hepatitis, including cholestatic jaundice and hepatic necrosis, elevation of serum transaminases and bilirubin, pseudomembranous enterocolitis, pancreatitis, stomatitis, glossitis, nausea, emesis, abdominal pain, diarrhea, anorexia.
Genitourinary
Renal failure, interstitial nephritis, BUN and serum creatinine elevation, renal insufficiency, anuria, crystalluria, and nephrotoxicity in association with cyclosporine.

Neurologic
Asepticmeningitis, convulsions, peripheralneuritis, ataxia, vertigo, tinnitus, headache.
Psychiatric
Hallucinations, depression, apathy, nervousness.
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. Diuresis and hypoglycemia have occurred rarely in patients receiving sulfonamides.
Musculoskeletal
Arthralgia and myalgia. Cases of rhabdomyolysis have been reported with SEPTRA, mainly in AIDS patients.
Respiratory System
Cough, shortness of breath, pulmonary infiltrates, acute eosinophilic pneumonia, acute and delayed lung injury, interstitial lung disease, and acute respiratory failure (see WARNINGS).
Cardiovascular System
QT prolongation resulting in ventricular tachycardia and torsade de pointes, circulatory shock.
