Drospirenone and ethinyl estradiol are the two active ingredients in a combined oral contraceptive (COC) pill used for women’s health. This medication belongs to the class of hormonal birth control products that contain both a progestin (drospirenone) and an estrogen (ethinyl estradiol). In Hong Kong, it is available by prescription only and is regulated by the Department of Health. The pill is supplied in a 3 mg drospirenone / 0.03 mg ethinyl estradiol strength and is taken in tablet form.
The two hormones work together to prevent pregnancy:
When taken daily, the pills keep hormone levels steady enough to block the normal menstrual cycle, preventing the ovary from releasing an egg (ovulation). Because both hormones are present, the pill also helps regulate menstrual bleeding and can improve acne in some users.
In Hong Kong, the combination pill is approved for the following indications:
These uses are supported by regulatory approval and clinical guidelines for combined oral contraceptives.
If any of these conditions apply, a healthcare provider should evaluate the risks and benefits before prescribing the medication.
These effects are usually transient and often improve after the first month of consistent use.
If any of these symptoms appear, seek urgent medical attention.

If you are already receiving estrogen or progestin for hormone replacement, using a combined oral contraceptive may lead to excess hormone exposure. Discuss alternatives such as progestin-only methods with your provider.
A severe or sudden headache could signal a serious vascular event. Seek immediate medical attention rather than waiting for the next scheduled visit.
No. Combined oral contraceptives prevent pregnancy but do not provide protection against STIs. Use condoms in addition to the pill if STI protection is needed.
Smoking, especially in women aged 35 years or older, significantly increases the risk of blood clots when combined with estrogen-containing contraceptives. Non-smokers or those who quit are safer candidates.
Yes, you can start the new pill on the day you would normally start a placebo week of your previous pack, provided the dosage strengths are comparable. Confirm the transition plan with your prescriber.
The schedule is designed to provide a predictable withdrawal bleed. Some clinicians may prescribe a continuous-use regimen (no placebo week) for specific conditions, but this should be individualized.
Fertility generally returns quickly after stopping the pill, often within one to three menstrual cycles. However, individual timing can vary.
No specific foods need to be avoided. Maintaining a balanced diet supports overall health, but grapefruit juice can affect hormone metabolism in some individuals and should be discussed with a provider.
Drospirenone has anti-androgenic and mild potassium-sparing effects, which may benefit women with acne or bloating. Other progestins have different side-effect profiles; the choice depends on individual health needs.
