Oekolp Forte Ovula (Estriol)

Estriol acts on estrogen‑dependent pathways to address several gynecological and hormonal conditions.

• Menopausal symptom relief: Reduces hot flashes, night sweats and vaginal dryness.
• Osteoporosis prevention: Helps maintain bone mineral density in post‑menopausal women.
• Hypo‑estrogenic states: Supports estrogen levels in women with ovarian insufficiency or after oophorectomy.

• Estriol binds to estrogen receptors (ERα and ERβ) throughout the body, acting as a weaker agonist compared with estradiol. This selective activation modulates gene transcription involved in reproductive tissue maintenance, bone metabolism, and thermoregulatory control, thereby providing estrogenic effects with a comparatively lower potency.

Adverse reactions may occur with estriol therapy and should be monitored.

Common Side Effects

• Nausea: mild to moderate gastrointestinal upset.
• Breast tenderness: transient swelling or discomfort.
• Headache: occasional tension‑type headaches.
• Vaginal spotting: light bleeding between periods.
• Fluid retention: mild peripheral edema.
• Mood changes: irritability or mild depressive symptoms.

Serious or Rare Side Effects

• Thromboembolic events: deep vein thrombosis or pulmonary embolism.
• Hepatic dysfunction: abnormal liver enzymes or jaundice.
• Endometrial hyperplasia: abnormal thickening of the uterine lining.
• Allergic reactions: rash, pruritus or anaphylaxis.
• Visual disturbances: sudden loss of vision or blurred sight.

Estriol should be used with careful clinical oversight and patient education.

• Contraindications: known estrogen‑dependent tumor or active thromboembolic disease.
• Cardiovascular risk: assess history of hypertension, stroke or myocardial infarction.
• Liver function: monitor hepatic enzymes in patients with liver disease.
• Bone health: evaluate baseline bone mineral density before long‑term use.
• Store at ambient temperature: keep below 25°C in the original packaging, protected from moisture.

Estriol may interact with several drug classes, altering efficacy or safety.

Major Interactions (Avoid)

• Anticoagulants: increased risk of bleeding.
• CYP3A4 inhibitors: elevated estriol plasma concentrations.
• Hormonal contraceptives: potential reduction in contraceptive effectiveness.

Moderate Interactions (Monitor Closely)

• Antihypertensives: possible attenuation of blood‑pressure‑lowering effect.
• Thyroid hormones: may require dosage adjustment of levothyroxine.
• Antifungal azoles: modest increase in estriol levels.
