Drospirenone + Ethinylestradiol (0.02 mg)

Indications

This tablet is indicated for:
  • As an oral contraceptive
  • Treatment of moderate acne vulgaris
  • Treatment of premenstrual dysphoric disorder (PMDD)

Pharmacology

This contains two active ingredients- Ethinylestradiol and Drospirenone. Ethinylestradiol is a synthetic version of estrogen and Drospirenone is a synthetic form of progesterone. The hormonal components of this preparation inhibit ovulation by suppressing gonadotropin release. Secondary mechanisms, which may contribute to the effectiveness of this tablet as a contraceptive, include changes in the cervical mucus (which increase the difficulty of sperm penetration) and changes in the endometrium (which reduce the likelihood of implantation).

Drospirenone has antimineralocorticoid activity, counteracting estrogen-related sodium retention. In combination with Ethinyloestradiol, Drospirenone displays a favorable lipid profile with an increase in high-density lipoprotein HDL. Drospirenone exerts antiandrogenic activity and does not counteract the ethinyloestradiol-related sex hormone-binding globulin increase which is useful for binding and inactivating the endogenous androgens.

Dosage

To achieve maximum contraceptive effectiveness tablets must be taken in the order directed on the package every day at about the same time. Tablet-taking should be started with the first pink tablet of the upper row & have to continue daily for 24 consecutive days. After completion of pink tablet, white tablet should be taken from 25th day to 28th day. Withdrawal bleeding usually starts on days 2-3 after starting the white tablets & don't stop taking white tablets though your menstruation is already started. Each subsequent new pack is started on the day after the last white tablet of the previous pack.

No preceding hormonal contraceptive use in the past month: Tablet taking has to start on day 1 of the woman’s menstrual cycle. The woman should be instructed to take the first light pink active tablet from the upper row of this tablet according to the direction and in this case no additional methods of contraception are required. Starting on days 2-5 is allowed, but during the first cycle a barrier method is recommended in addition for the first 7 days of tablet-taking.

Administration

Management of Missed Tablets: Missed white pills from the last row of the blister are placebo tablets and thus can be disregarded.

Additionally you should use some other method of contraception (like a condom) until next 7 days.

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 light pink tablet of the top row of a fresh pack from the first day of next menstruation.

Do not start the next pack of this tablet until your doctor has checked you are not pregnant.

How to Delay a Period: To delay period women should continue with another new pack of this tablet just after finishing the light pink 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 light pink color tablet of the second pack. When women wish their 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 4 day white inactive tablet interval.

Advice in case of Vomiting: If vomiting occurs within 3-4 hours after light pink 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 (light pink color) needed from a back up pack after vomiting.
