It inhibits blood clots, so if you're on blood-thinning medications, stay from bromelain. It also isn't advisable to take bromelain immediately following surgery, as the anti-inflammatory properties can counteract anti-coagulation medications. Ask your doctor when it's safe to consume bromelain. Some people may experience side effects of bromelain in the gut, namely nausea, changes in bowel movements, and increased gas. Additionally, while bromelain allergies are rare, they do exist. If you notice a rash or swelling after eating pineapple or bromelain supplements, consult your physician.
