Drug Precautions ::

 Precautions

Pregnancy: Safety not established. Lactation: Undetermined. Children: Safety and efficacy not established in children < 14 yr, except use of IV form in infants. CNS effects: May aggravate depression or other psychiatric disorders, epilepsy, or Parkinsonism; use with caution. Electrolyte imbalance: IV indomethacin may suppress water excretion to greater extent than sodium excretion; monitor electrolytes and renal function. GI effects: Usually not given to patients with active GI lesions or history of recurrent GI lesions. Renal impairment: NSAIDs may worsen preexisting renal dysfunction.

PATIENT CARE CONSIDERATIONS


Drug Side Effects ::

 Adverse Reactions

CV: Peripheral edema; water retention; worsening or precipitation of CHF. CNS: Dizziness; headache; drowsiness; confusion. EENT: Visual disturbances; tinnitus. GI: Gastric distress; occult blood loss; nausea; diarrhea; vomiting; ulceration; perforation. GU: Acute renal insufficiency; interstitial nephritis; hyponatremia; renal papillary necrosis. HEMA: Leukopenia. META: Hyperuricemia; hyperkalemia.

Drug Mode of Action ::  

 Action Decreases inflammation, pain, and fever, probably through inhibition of cyclooxygenase activity and prostaglandin synthesis.

Drug Interactions ::

 Interactions

Anticoagulants: May increase risk of gastric erosion and bleeding. Beta-blockers, ACE inhibitors: Antihypertensive effects may be decreased. Diflunisal: Diflunisal may decrease the renal clearance and significantly increase indomethacin plasma concentrations that may produce toxicity. Digoxin: May increase digoxin levels. Lithium: May decrease lithium clearance. Loop diuretics: May decrease diuretic effects. Methotrexate: May increase methotrexate levels. Penicillamine: Indomethacin may increase the bioavailability of pencillamine. Potassium-sparing diuretics: Effects of potassium-diuretics may be decreased. Concomitant administration may increase serum potassium levels. Sympathomimetics: Indomethacin and phenylpropanolamine coadministration may result in increased blood pressure.

Drug Assesment ::

 Assessment/Interventions

  • Obtain patient history, including drug history and any known allergies (especially allergy to aspirin).
  • Observe for signs of rhinitis, asthma and urticaria.
  • Assess patient with arthritis: Note type, location, and intensity of limitation of movement and pain before and 1 to 2 hr after administration of standard-release medication and 4 to 6 hr after sustained-release form.
  • Monitor BUN, creatinine, CBC, serum potassium, AST, and ALT prior to therapy and periodically during long-term therapy. Urine glucose and protein concentrations may be increased; leukocyte and platelet count may be decreased; bleeding time may be prolonged for 1 day after discontinuation.
  • Assess for blurred vision and tinnitus, which could indicate toxicity.
  • Observe for signs of GI bleeding (eg, black stools, occult blood loss) throughout therapy.
  • Assess for mood changes, depression, hallucinations, confusion.
  • Report signs of adverse reactions to physician immediately, especially in elderly patients.
OVERDOSAGE: SIGNS & SYMPTOMS
  Nausea, vomiting, headache, dizziness, mental confusion, disorientation, lethargy, paresthesias, numbness, convulsions, tinnitus

Drug Storage/Management ::

 Administration/Storage

  • Administer oral medication with food, milk, or antacids to minimize GI upset.
  • Do not crush, break, or allow patient to chew sustained-release capsules.
  • Shake suspension before giving, do not mix with antacid or any other liquid.
  • Refrigerate oral suspension and suppositories. Protect oral suspension from freezing.

Rectal suppositories

  • Encourage patient to retain rectal suppositories for 1 hr.

IV for patent ductus

  • Dilute 1 mg/ml or more with normal saline or Sterile Water for Injection without preservative. Administer over 5 to 10 sec. May also be given as retention enema or via orogastric tube.

Drug Notes ::

 Patient/Family Education

  • Tell patient to take medication with food, milk, or antacids if GI upset occurs. Inform physician if stomach distress continues.
  • Caution patient to avoid aspirin, alcohol, and ibuprofen while taking this medication.
  • Instruct patient to report the following symptoms to physician: Skin rash, itching, black stools, unusual bruising or bleeding, visual disturbances, tinnitus, weight gain, edema, or persistent headache.
  • Advise patient that drug may cause drowsiness and to use caution while driving or performing other tasks requiring mental alertness.
  • Explain that therapeutic effects for rheumatoid arthritis may not be seen for up to 1 mo of drug use.
  • Explain purpose of medication and, for parents of infant with ductus arteriosus, emphasize need for frequent monitoring.
