Ethinyl Estradiol and Norgestimate

Overview

What is it?

Ethinyl estradiol and norgestimate are synthetic hormones used in combination as an oral contraceptive. Ethinyl estradiol is a synthetic form of estrogen, while norgestimate is a synthetic progestin derived from testosterone. This combination is not naturally occurring but is widely used in birth control pills and has been approved by regulatory agencies like the FDA and EMA for treating acne in women who also need contraception.

How does it work?

Ethinyl estradiol and norgestimate work together to combat acne by targeting the hormonal factors that contribute to its development. Acne is often linked to excess androgen (male hormone) activity, which increases sebum (oil) production and leads to clogged pores. Ethinyl estradiol helps reduce the levels of active androgens in the body, while norgestimate has anti-androgenic properties, meaning it blocks the effects of androgens. Together, they reduce sebum production and prevent follicular hyperkeratinization (clogging of hair follicles), which are key factors in acne formation .

What are the benefits?

The combination of ethinyl estradiol and norgestimate offers several benefits for acne treatment. It effectively reduces sebum production, decreases the number of inflammatory and non-inflammatory acne lesions, and improves skin clarity. Additionally, it provides the added benefit of contraception, making it a convenient option for women who need both acne treatment and birth control .

What does the research say?

Research shows that ethinyl estradiol and norgestimate are effective in treating moderate acne vulgaris. Clinical trials, including placebo-controlled studies, have demonstrated significant reductions in acne lesions compared to placebo. The combination has been shown to improve acne severity over time, with many patients experiencing clearer skin after several months of use . It is particularly effective for women whose acne is hormonally driven, as it addresses the underlying hormonal imbalances that contribute to acne .

Side Effects

Moderate

Nausea

Nausea is a common side effect, especially when starting the medication, but it often subsides over time .

Headaches

Headaches may occur due to hormonal changes, but they are usually mild and manageable .

Breast tenderness

Breast tenderness is a temporary side effect caused by the hormonal adjustments in the body .

Mood changes

Mood changes, such as irritability or mild depression, can occur but are typically not severe .

Weight gain

Weight gain is rare and usually minimal, but some individuals may notice slight changes .

Irregular bleeding

Irregular bleeding or spotting between periods is common during the first few months of use but often resolves as the body adjusts .

Evidence

Moderate
