Can naproxen sodium be taken before sigmoid colonoscopy?

Sometimes during colonoscopy, biopsies are taken and sent to the lab for testing. Taking tissue samples can result in minor amounts of bleeding, and for this reason, any anti-clotting agent should not be taken in order to avoid hemorrhaging or blood loss. This is why patients are instructed to avoid ibuprofen, aspirin, coumadin, etc..

Unfortunately, naproxen (Aleve) falls into this category and therefore should not be taken up to 7 days prior to colonoscopy as complications may arise with internal bleeding. In addition, naproxen can cause disturbances within the GI tract which could, potentially, interfere with the procedure and results.

Best of luck to you with your endoscopy, and I hope this was helpful.
