Ketorolac Use in Early Pregnancy

Alternatives and Safety Considerations

The European League Against Rheumatism (EULAR) recommends ibuprofen as the nonsteroidal anti-inflammatory drug (NSAID) with the most reassuring safety data for short-term use (7-10 days) in the lowest effective dose during the first and second trimester 1, 2
Early pregnancy exposure to NSAIDs (ibuprofeno, diclofenaco) does not show evidence of increased risk of spontaneous abortion or teratogenicity 1, 2
All NSAIDs should be discontinued after the 28th week of gestation due to increased fetal sensitivity to NSAID-related risks, including oligohydramnios and premature closure of the ductus arteriosus 1, 2
The American Academy of Pediatrics and other guidelines are not mentioned, however, the FDA classifies ketorolac as Category C in pregnancy, indicating it should only be used if the potential benefit justifies the potential risk to the fetus, although this fact is not directly cited, ibuprofen is recommended as a safer alternative 1, 2
Breastfeeding data show low levels in breast milk and are compatible with breastfeeding 4

For patients requiring analgesia during early pregnancy, paracetamol (acetaminophen) is recommended as the first-line treatment in the lowest effective dose for the shortest duration, however this fact is only cited from Praxis Medical Insights, a more reliable source is needed, alternatively, ibuprofen 200-400 mg every 6-8 hours can be used as a second-line treatment, limiting the duration to 7-10 days maximum, in the first and second trimester until week 28 1, 2
