Harmonet

Harmonet is a prescription combined oral contraceptive tablet that contains the synthetic estrogen ethinylestradiol and the progestogen gestodene. Formulated as a single‑dose oral tablet, it is marketed in the European Union for hormonal contraception. The product works by suppressing ovulation and altering cervical mucus and the endometrial lining to prevent pregnancy. It is taken once daily in a 21‑day active regimen followed by a 7‑day hormone‑free interval.

Harmonet is indicated for the prevention of pregnancy in women of reproductive age who choose an oral hormonal method.

- Primary use as a combined oral contraceptive for reliable birth control. - May be prescribed to regulate menstrual cycles and reduce menstrual flow. - Can be used to manage hormonally‑related acne in some patients. - Provides a reversible method of contraception that does not affect future fertility. - May be selected for patients seeking a low‑dose estrogen formulation.

Like other combined oral contraceptives, Harmonet may cause a range of side effects, most of which are mild and transient.

Common: - Nausea, vomiting or mild stomach upset, especially during the first cycles. - Breast tenderness, swelling or a feeling of fullness. - Headache, including mild migraine‑type pain. - Spotting, breakthrough bleeding or irregular periods during the initial months. - Mood fluctuations, mild depression or irritability.

Before starting Harmonet, certain health conditions and risk factors should be evaluated to ensure safe use.

- Personal or family history of blood‑clot disorders, stroke, or heart disease. - Uncontrolled hypertension, diabetes with vascular complications, or severe liver disease. - Smoking cigarettes, especially in women over 35 years of age. - Current pregnancy, suspected pregnancy, or breastfeeding. - Use of estrogen‑containing hormone therapy or other combined hormonal products. - Known allergy to ethinylestradiol, gestodene, or any tablet excipients.

Harmonet can interact with several medicines, which may reduce its effectiveness or increase the risk of adverse events.

Avoid: - Strong enzyme inducers such as rifampicin, carbamazepine, phenytoin, or St. John’s wort. - Certain antiretroviral agents (e.g., protease inhibitors) that markedly lower hormone levels.

Use with caution: - Antifungal agents like ketoconazole or itraconazole. - Antidepressants, especially selective serotonin reuptake inhibitors (SSRIs). - Diuretics and antihypertensive agents that may affect blood pressure control. - Herbal supplements that influence estrogen metabolism.
