Novelon is a combined oral contraceptive (COC) pill used to prevent pregnancy. It belongs to the women’s health category and contains two active ingredients: ethinylestradiol (a synthetic estrogen) and desogestrel (a progestogen). The tablet is formulated as a pill delivering a fixed dose of 0.15 mg ethinylestradiol and 0.3 mg desogestrel. In Hong Kong, Novelon is a prescription-only medication regulated by the Department of Health.
Novelon prevents pregnancy by using the complementary actions of its estrogen and progestogen components:
Together, these mechanisms prevent ovulation, impede sperm penetration, and modify the uterine environment, creating multiple barriers to fertilisation and implantation. Oral absorption of the tablet is rapid, with peak plasma concentrations reached within 1-2 hours. The hormones are metabolised primarily in the liver and excreted via urine and bile.
Novelon is approved in Hong Kong for the following indications:
The contraceptive effect is reliable when the pill is taken consistently at the same time each day.
Clinical studies have demonstrated that combined oral contraceptives containing ethinylestradiol and a third-generation progestogen (such as desogestrel) can reduce acne lesions by decreasing circulating androgens. While Novelon is not formally approved for acne in Hong Kong, it may be prescribed off-label for this purpose under medical supervision.
Disclaimer: Off-label use of Novelon for acne requires individual risk assessment by a qualified healthcare professional.
If any of the above conditions apply, consult a healthcare provider before initiating Novelon.
Patients should disclose all medications, supplements, and herbal products to their prescriber.
Note: Dosing must be individualized by a qualified healthcare provider, especially for women with renal or hepatic impairment.

Using two hormonal methods simultaneously is unnecessary and may increase side-effect risk. Choose one method unless a provider advises otherwise, such as adding a backup barrier method during the initial weeks.
Mild tenderness often resolves within a couple of cycles. Persistent or painful swelling should prompt a visit to a healthcare professional to rule out other causes.
Taking the pill at the same time each day-morning or night-helps maintain stable hormone levels and reduces the chance of missed doses.
Smoking, especially in women over 35, raises the risk of cardiovascular events when combined with estrogen-containing contraceptives. Smoking cessation is strongly recommended.
Yes. Maintain the regular dosing interval based on your home time zone. If a dose is delayed more than 12 hours, follow the missed-dose instructions and use backup contraception for the next 7 days.
The inactive ingredients may include lactose and small amounts of gluten-derived excipients. Patients with severe intolerances should consult the prescribing information or pharmacist.
Migraine with aura is a contraindication. Women with migraine without aura should discuss their individual risk with a clinician before starting the pill.
Estrogen can raise serum sex-hormone-binding globulin (SHBG) and may slightly alter certain hormone assays. Inform laboratory personnel of COC use when relevant.
Novelon contains a low-dose estrogen (0.15 mg) paired with desogestrel, a third-generation progestogen associated with a favorable bleeding profile. Other brands may use different estrogen doses or progestogen types, influencing side-effect patterns.
