  • See "What Are Side Effects Associated with Using Celecoxib?"

Long-Term Effects

  • Long-term administration of nonsteroidal anti-inflammatory drugs (NSAIDs) may result in renal papillary necrosis and other kidney (renal) injury; patients at greatest risk include elderly individuals; those with impaired kidney (renal) function, too much fluid in the blood (hypovolemia), heart failure, liver dysfunction, or salt depletion, and those taking diuretics, angiotensin-converting enzyme inhibitors, or angiotensin-receptor blockers
  • Anemia may occur; monitor hemoglobin or hematocrit in long-term treatment patients
  • See "What Are Side Effects Associated with Using Celecoxib?"

Cautions

  • Congestive heart failure, high blood pressure
  • Increased risk of adverse cardiovascular events and skin reactions
  • Caution in asthma (bronchial), bleeding disorder, sudden difficulty breathing, duodenal/gastric/peptic ulcer, kidney (renal) impairment
  • Risk of gastrointestinal bleeding, ulceration, and perforation
  • Long-term administration of NSAIDs may result in renal papillary necrosis and other kidney (renal) injury; patients at greatest risk include elderly individuals; those with impaired kidney (renal) function, too much fluid in the blood (hypovolemia), heart failure, liver dysfunction, or salt depletion, and those taking diuretics, angiotensin-converting enzyme inhibitors, or angiotensin-receptor blockers
  • Anemia may occur; monitor hemoglobin or hematocrit in long-term treatment patients
  • Heart Failure (HF) risk

Pregnancy and Lactation

  • Use celecoxib during pregnancy with caution if benefits outweigh risks
  • Animal studies show risk and human studies are not available, or neither animal nor human studies were done
  • At 30 weeks gestation or greater, use of celecoxib may cause premature closure of ductus arteriosus
  • Therefore, use celecoxib during pregnancy only in LIFE-THREATENING emergencies when no safer drug is available
  • There is positive evidence of human fetal risk
  • Quebec Pregnancy Registry identified 4705 women who had spontaneous abortions by 20 weeks' gestation; each case was matched to 10 control subjects (n=47,050) who had not had spontaneous abortions; exposure to nonaspirin NSAIDs during pregnancy was documented in approximately 7.5% of cases of spontaneous abortions and in approximately 2.6% of controls
