Ethinylestradiol is a synthetic oestrogen while drospirenone is a progestogen with antimineralocorticoid and antiandrogenic activity. Combined oral contraceptives act by suppressing the gonadotropins. Oral contraceptives also produce changes in the cervical mucus, making it less favorable for sperm penetration even if ovulation occurs.

How to Take Ethinylestradiol & Drospirenone
To achieve maximum contraceptive effectiveness, Ethinylestradiol & Drospirenone must be taken in the order directed on the package and at intervals not exceeding 24 hours. Women should be instructed to take the tablets at about the same time every day, preferably after the evening meal or at bedtime. One tablet is to be taken daily for 28 consecutive days. Each subsequent pack is started on the day after the current pack is completed.
If you have decided to take Ethinylestradiol & Drospirenone for contraception, wait for your next menstruation begins.
From the first day of your menstruation, start taking the first light yellow tablet from the left corner of the top row (with arrow mark) of your Ethinylestradiol & Drospirenone tablet pack.
Continue taking one light yellow tablet each day along the arrow mark.
After taking 21 light yellow tablets for 21 days, then continue taking one white placebo tablet every day from the last row in the pack for next 7 days.
It is most likely that your menstruation will start while taking the white tablets. Do not discontinue taking the white tablets. Taking of the white tablets for 7 days will help you keep your tablet taking routine. If your menstruation does not start during this time, check with your doctor to make sure you are not pregnant.
After completing the seven white tablets, start taking light yellow tablets from another Ethinylestradiol & Drospirenone pack and continue taking the tablet as long as you don’t want to be pregnant.
Management of Missed Tablets
If you forgot to take a tablet one day, take the missed tablet as soon as you remember. This may mean taking two tablets the very next day. Additionally you should use some other method of contraception while you are taking the tablets & until your next menstruation.
If you forget to take the tablets for two continuous days, then it is likely that you will no longer be protected against pregnancy. You should therefore discontinue taking the tablet and adopt some other temporary methods (condom/foam tablet) till your next menstruation. Discard the unfinished pack of tablets and start taking tablets from the very first white tablet of the top row from a fresh pack from the first day of next menstruation.
How to Delay a Period
To delay a period you should continue with another new pack of Ethinylestradiol & Drospirenone just after finishing the light yellow active tablet of the present pack (that is no need to take white placebo tablet of present pack). The extension can be carried on for as long as wished until the end of the second pack. When you wish your period to begin, just stop tablet taking. While using the second pack woman may have some breakthrough bleeding or spotting. Start with your next pack after the usual 7 day white inactive tablet interval.
Advice in Case of Vomiting
If vomiting occurs within 4 hours after white active tablet taking, absorption may not be complete. In such an event, the advice concerning Management of Missed Tablets is applicable. The woman must take the extra active tablet(s) needed from a back up pack after vomiting.
