Endometriosis Combined Pills

Combined Oral Contraceptives (Estrogen + Progesterone) in Endometriosis – A Comprehensive Guide

What Are Combined Oral Contraceptives?

Combined oral contraceptives (COCs) are hormonal medications containing estrogen and progesterone (progestin). They are widely used in the treatment of endometriosis for pain control and to suppress disease activity.

Mechanism of Action in Endometriosis

COCs suppress ovulation, stabilize estrogen levels, and reduce the growth of endometriotic lesions. They also alleviate inflammation and pain by reducing menstrual bleeding.

How Are They Used?

Combined pills can be used cyclically (21 days on + 7 days off) or continuously (without interruption). Continuous use is generally preferred in patients with endometriosis.

Advantages

Their most significant advantages include pain reduction, regulation of menstrual cycles, ease of use, and suitability for long-term treatment.

In Which Patients Are They Preferred?

They are preferred in mild to moderate endometriosis, for preventing recurrence after surgery, and as a first-line treatment in young patients.

Side Effects

Nausea, headache, breast tenderness, breakthrough bleeding, and rarely an increased risk of blood clots may occur.

Migraine and Combined Pills

Estrogen-containing pills should be used with caution in patients with migraine with aura. Alternative treatments may be preferred in these patients.

Effect on Fertility

They suppress ovulation during use, but fertility generally returns after discontinuation.

Progesterone Alone or Combined?

While combined pills provide cyclic control, progesterone treatments may offer stronger suppression. Patient-specific selection should be made.

When Are They Not Preferred?

They are not preferred in patients who smoke and are over 35 years old, those with a high risk of thrombosis, and in certain cardiovascular diseases.

Conclusion

Combined oral contraceptives are an effective and widely used option in the treatment of endometriosis. Successful outcomes are achieved with proper patient selection and regular follow-up.
