Before using

Often, the cause of an early natural abortion is due to a defective female egg. Using this drug does not fix a defective egg and may get in the way of expelling it. Some medicines or medical conditions may interact with this medicine. INFORM YOUR DOCTOR OR PHARMACIST of all prescription and over-the-counter medicine that you are taking. ADDITIONAL MONITORING OF YOUR DOSE OR CONDITION may be needed if you are taking rifampin. Inform your doctor of any other medical conditions, including diabetes, any allergies, pregnancy, or breast-feeding.
