    For the treatment of moderate to severe pain.

    For treatment of acute gouty arthritis.

    • History of proctitis or recent rectal bleeding (suppositories)

    • Ulcerative colitis

    Use caution in patients with history of bronchospasm, cardiac disease, CHF, hypertension, hepatic or renal impairment

    Long-term administration of NSAIDs may result in renal papillary necrosis and other renal injury; patients at greatest risk include elderly individuals, those with impaired renal function, hypovolemia, heart failure, liver dysfunction, or salt depletion, and those taking diuretics, angiotensin-converting enzyme (ACE) inhibitors, or angiotensin receptor blockers

    Prolonged use may cause corneal deposits and retinal disturbances; discontinue if visual changes observed

    Risk of aggravation of psychiatric disturbances, epilepsy, fluid retention, or Parkinson disease

    Reduction in cerebral blood flow associated with rapid IV infusion

    Serious skin adverse events (eg, exfoliative dermatitis, Stevens-Johnson Syndrome, and toxic epidermal necrolysis) reported; discontinue is symptoms occur

    Pregnancy; Use of NSAIDs, including indomethacin capsules, can cause premature closure of fetal ductus arteriosus and fetal renal dysfunction leading to oligohydramnios and, in some cases, neonatal renal impairment; because of these risks, limit dose and duration of therapy to between about 20 and 30 weeks of gestation, and avoid use at about 30 weeks of gestation and later in pregnancy

    Lactation

    Based on available published clinical data, drug may be present in human milk; the developmental and health benefits of breastfeeding should be considered along with mother’s clinical need for therapy and any potential adverse effects on breastfed infant from drug or from underlying maternal condition
