Talk to your healthcare provider before taking this medicine if you know or suspect that you are pregnant. Contact your healthcare provider if you think you may be pregnant and you have taken this medicine.
If you have severe abdominal pain, you may have a pregnancy outside the womb, which is called an ectopic or tubal pregnancy. Call your health care provider or go to the nearest emergency room right away if you think this is happening.
