Oestrogel (Estradiol)

Oestrogel is an estrogen replacement that acts on the hormonal pathways involved in female reproductive health.

• Menopausal symptoms: alleviates hot flashes, night sweats and vaginal dryness.
• Hypo‑estrogenism after oophorectomy: restores systemic estrogen levels.
• Primary ovarian insufficiency: supports development of secondary sexual characteristics and bone health.

• Estradiol in Oestrogel is absorbed through the skin and enters systemic circulation, where it binds to intracellular estrogen receptors (ERα and ERβ). This receptor activation modulates gene transcription, leading to restoration of estrogen‑dependent physiological processes such as regulation of the menstrual cycle, bone remodeling, and lipid metabolism.

Adverse reactions to Oestrogel vary in frequency and severity.

Common Side Effects

• Skin irritation at application site: redness, itching or mild rash.
• Headache: transient mild to moderate pain.
• Nausea: occasional upset stomach.
• Breast tenderness: mild swelling or discomfort.
• Mood changes: irritability or mild depressive symptoms.

Serious or Rare Side Effects

• Venous thromboembolism: deep vein thrombosis or pulmonary embolism.
• Stroke or transient ischemic attack.
• Hepatotoxicity: abnormal liver function tests.
• Endometrial hyperplasia or carcinoma.
• Severe allergic reaction: anaphylaxis or angio‑edema.

When using Oestrogel, patients and clinicians should consider several safety measures.

• Contraindications: do not use if history of blood clots or estrogen‑dependent tumors.
• Monitoring: periodic assessment of blood pressure, lipid profile and liver enzymes.
• Breast health: perform regular mammograms and breast examinations.
• Cardiovascular risk: evaluate personal and family history of thromboembolic events.
• Bone health: assess bone mineral density in long‑term therapy.
• Store at room temperature: keep in original packaging, protect from moisture and direct sunlight.

Estradiol may interact with several other medicines, altering its effectiveness or safety profile.

Major Interactions (Avoid)

• Combined oral contraceptives: increased risk of thromboembolic events.
• Anticoagulants (e.g., warfarin): potentiated anticoagulant effect, requiring dose adjustment.\nModerate Interactions (Monitor Closely):
• Antiepileptic drugs (phenylenediamine …)
