How should I use this medication?
This medication is taken in 28-day cycles consisting of 1 tablet daily for 21 days, followed by a 7-day interval without medication (i.e., 3 weeks on, 1 week off). Tablets should be taken at the same time each day. Treatment is usually started on the first day of menstrual bleeding. Often, several months of treatment are needed before improvement is seen. Once the acne has completely resolved, this medication is usually continued for another 3 or 4 cycles and then stopped. This medication may be restarted if your acne returns.
If spotting or breakthrough bleeding occurs during the 3 weeks during which this medication is being taken, continue taking this medication. The spotting or breakthrough bleeding is usually temporary. If bleeding is persistent or lasts a long time, contact your doctor.
If your menstrual period fails to occur during the 7-day tablet-free interval, do not start the next medication cycle and contact your doctor.
