From your 2021 MCME Interactive day:
If you can see blood in the urine (pink or red!) then NSAIDs are contraindicated. The OBHG Companion Document says “trace urine” is not considered an active bleed. However, trace urine by definition cannot be seen by the naked eye and is only detectable via urinalysis. Therefore, if a patient tells you they saw blood in their urine, withhold ibuprofen and ketorolac.
