Side effect of bromeline?

Some of the more common side effects of bromelain include indigestion, nausea and diarrhea. Other side effects may include vomiting, increased heart rate, drowsiness and abnormal uterine bleeding or heavy menstruation. Some people who are allergic to pineapples should avoid bromelain, as well as those with allergies to latex, carrot, celery, fennel, rye, wheat, papain, bee venom or grass, birch or cypress pollens. Theoretically, bromelain may increase the risk of bleeding, so people with bleeding disorders or ulcers and those taking medication that can increase the risk of bleeding should only use bromelain under the supervision of their physician. It should not be taken two weeks before or after dental procedures or surgery.
