Contraindications for NSAID Use in Pediatric Patients

Absolute Contraindications

Active GI bleeding or peptic ulcer disease represents a clear contraindication, as NSAIDs are known to cause GI bleeding and ulceration even with short-term use, according to the American Academy of Family Physicians 1.
Pre-existing renal disease or renal insufficiency is a major contraindication, as NSAIDs can cause acute renal failure particularly in children with compromised kidney function, as stated by the American Academy of Family Physicians 1.
Baseline renal function tests should be obtained before initiating NSAIDs, with monitoring every 6-12 months during chronic use, as recommended by the American College of Rheumatology 2, 3.
Cirrhotic liver disease is a contraindication because bleeding problems and renal failure become significantly more likely, according to the American Association for the Study of Liver Diseases 4.
Concurrent anticoagulation therapy increases GI bleeding risk 5-6 fold and should be avoided, as warned by the American Academy of Family Physicians 1, 5.

NSAIDs are contraindicated when breastfeeding a neonate with jaundice because most NSAIDs displace bilirubin, potentially worsening hyperbilirubinemia, as noted by the American Academy of Pediatrics 1.

Children with asthma, particularly those with nasal polyps or recurrent sinusitis, should be evaluated for aspirin-exacerbated respiratory disease before NSAID use, as recommended by the American Academy of Family Physicians 1.
AERD prevalence reaches up to 21% in adults with asthma, though it is rarely reported in pediatric populations, according to the American Academy of Allergy, Asthma, and Immunology 1, 6.

The main risk to children taking NSAIDs is dosage errors resulting in overdose, which can cause significant morbidity and death, as stated by the American Academy of Family Physicians 1.
For children requiring chronic NSAID therapy, CBC, liver function tests, and renal function tests should be monitored every 6-12 months, as recommended by the American College of Rheumatology 2, 3.

NSAIDs should be discontinued 6-8 weeks before term to avoid maternal effects and fetal effects, as recommended by the American College of Obstetricians and Gynecologists 1.
Women actively trying to conceive should avoid NSAIDs as they can block blastocyst implantation, as warned by the American College of Obstetricians and Gynecologists 1.
Congestive heart failure represents a contraindication as NSAIDs can worsen fluid retention and increase blood pressure, according to the American Heart Association 7, 5.

Only 31-68% of children with suspected NSAID hypersensitivity have it confirmed on challenge, demonstrating the difficulty of relying on history alone, as noted by the American Academy of Allergy, Asthma, and Immunology 6.
One large randomized controlled trial showed ibuprofen and acetaminophen were equivalent in adverse event risk, with overall low rates, as reported by the American Academy of Family Physicians 1.

The American Academy of Family Physicians recommends that ibuprofen suspension is the preferred formulation for toddlers, rather than crushed tablets, as it allows for precise weight-based dosing and has been extensively studied for safety in young children 8

When crushing ibuprofen tablets is necessary, special attention must be given to accurate dose calculation based on the child's weight to avoid dosage errors resulting in overdose, which can cause significant morbidity and death 8
Crushed tablets mixed with food or liquid can be used under direct observation, though absorption characteristics may differ from suspension formulations 9

The American Academy of Family Physicians advises against relying on parents to estimate doses, and instead recommends providing exact milliliter measurements or tablet fractions based on the child's current weight 8
The American Academy of Family Physicians also warns against combination cold medications that may contain additional NSAIDs, leading to inadvertent overdose 8
Ensure childproof storage to prevent accidental ingestion 8
