The following adverse reactions are discussed in greater detail in other sections of the labeling: Cardiovascular Thrombotic Events GI Bleeding, Ulceration and Perforation Hepatotoxicity Hypertension Heart Failure and Edema Renal Toxicity and Hyperkalemia Anaphylactic Reactions Serious Skin Reactions Hematologic Toxicity Most common adverse reactions (incidence ≥ 3%) are headache, dizziness, dyspepsia, and nausea.

6.1 Clinical

Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice. In a gastroscopic study in 45 healthy subjects, the number of gastric mucosal abnormalities was significantly higher in the group receiving INDOCIN Capsules than in the group taking INDOCIN Suppositories or placebo. In a double-blind comparative clinical study involving 175 patients with rheumatoid arthritis, however, the incidence of upper gastrointestinal adverse effects with INDOCIN Suppositories or Capsules was comparable. The incidence of lower gastrointestinal adverse effects was greater in the suppository group. The adverse reactions for INDOCIN Capsules listed in the following table have been arranged into two groups: incidence greater than 1%; and incidence less than 1%. The incidence for group was obtained from 33 double-blind controlled clinical trials reported in the literature (1,092 patients). The incidence for group was based on reports in clinical trials, in the literature, and on voluntary reports since marketing. The probability of a causal relationship exists between INDOCIN and these adverse reactions, some of which have been reported only rarely. The adverse reactions reported with INDOCIN Capsules may also occur with use of the suspension. Table 1 Summary of Adverse Reactions for INDOCIN Capsules Incidence greater than 1% Incidence less than 1% GASTROINTESTINAL nausea* with or without vomiting dyspepsia* (including indigestion, heartburn and epigastric pain) diarrhea abdominal distress or pain constipation anorexia bloating (includes distension) flatulence peptic ulcer gastroenteritis rectal bleeding proctitis single or multiple ulcerations, including perforation and hemorrhage of the esophagus, stomach, duodenum or small and large intestines intestinal ulceration associated with stenosis and obstruction gastrointestinal bleeding without obvious ulcer formation and perforation of preexisting sigmoid lesions (diverticulum, carcinoma, etc.) development of ulcerative colitis and regional ileitis ulcerative stomatitis toxic hepatitis and jaundice (some fatal cases have been reported) intestinal strictures (diaphragms) pancreatitis CENTRAL NERVOUS SYSTEM headache (11.7%) dizziness* vertigo depression and fatigue (including malaise and listlessness) anxiety (includes nervousness) muscle weakness involuntary muscle movements insomnia muzziness psychic disturbances including psychotic episodes mental confusion drowsiness light-headedness syncope paresthesia aggravation of epilepsy and parkinsonism depersonalization coma peripheral neuropathy convulsion dysarthria SPECIAL SENSES tinnitus ocular — corneal deposits and retinal disturbances, including those of the macula, have been reported in some patients on prolonged therapy with INDOCIN blurred vision diplopia hearing disturbances, deafness CARDIOVASCULAR None hypertension hypotension tachycardia chest pain congestive heart failure arrhythmia; palpitations METABOLIC None edema weight gain fluid retention flushing or sweating hyperglycemia glycosuria hyperkalemia INTEGUMENTARY none pruritus rash; urticaria petechiae or ecchymosis exfoliative dermatitis erythema nodosum loss of hair Stevens-Johnson syndrome erythema multiforme toxic epidermal necrolysis HEMATOLOGIC None leukopenia bone marrow depression anemia secondary to obvious or occult gastrointestinal bleeding aplastic anemia hemolytic anemia agranulocytosis thrombocytopenic purpura disseminated intravascular coagulation HYPERSENSITIVITY None acute anaphylaxis acute respiratory distress rapid fall in blood pressure resembling a shock-like state angioedema dyspnea asthma purpura angiitis pulmonary edema fever GENITOURINARY None hematuria vaginal bleeding proteinuria nephrotic syndrome interstitial nephritis BUN elevation renal insufficiency, including renal failure MISCELLANEOUS None epistaxis breast changes, including enlargement and tenderness, or gynecomastia * Reactions occurring in 3% to 9% of patients treated with INDOCIN. (Those reactions occurring in less than 3% of the patients are unmarked.) Causal relationship unknown: Other reactions have been reported but occurred under circumstances where a causal relationship could not be established. However, in these rarely reported events, the possibility cannot be excluded. Therefore, these observations are being listed to serve as alerting information to physicians: Cardiovascular: Thrombophlebitis Hematologic: Although there have been several reports of leukemia, the supporting information is weak Genitourinary: Urinary frequency A rare occurrence of fulminant necrotizing fasciitis, particularly in association with Group Aβ hemolytic streptococcus, has been described in persons treated with nonsteroidal anti-inflammatory agents, including indomethacin, sometimes with fatal outcome

6.2 Postmarketing

Experience The following adverse reactions have been identified during postapproval use of indomethacin. Because these reactions are 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.

Skin and Appendages: Exfoliative dermatitis, Stevens-Johnson Syndrome (SJS), toxic epidermal necrolysis (TEN), and fixed drug eruption (FDE).
