How long can one blister pack of drospirenone and ethinyl estradiol tablets prevent pregnancy

Patient's question:

No

Doctor's answer:

Hello, it is generally not advisable to take emergency contraception more than twice a month or more than three times a year. Excessive use may lead to menstrual disorders. It is important to monitor your condition. If you experience menstrual disorders, you can take Wuji Baifeng pills or traditional Chinese herbal medicine for regulation. Maintaining a positive mood and getting sufficient sleep are also helpful for restoring your cycle.
