Oestrogel (Estradiol)

Estradiol, the active ingredient in Oestrogel, is a natural estrogen presented as a transdermal gel for topical use. It is used to treat estrogen deficiency in postmenopausal women and other conditions requiring estrogen supplementation.

Estradiol in Oestrogel acts on the estrogen pathway to manage conditions related to estrogen deficiency.

Menopausal symptoms: alleviates hot flashes, vaginal dryness, and helps maintain bone density. Hypoestrogenism due to ovarian failure: restores physiological estrogen levels. Hormone therapy after oophorectomy: provides necessary estrogen replacement.

Before initiating therapy, consider the following precautions: - Assess cardiovascular risk: evaluate history of thromboembolic events. - Screen for hormone‑sensitive cancers: avoid if active breast or endometrial cancer. - Monitor liver function: adjust use in hepatic impairment. - Contraindicated in pregnancy: do not use in pregnant women. - Contraindicated while breastfeeding: avoid in lactating women.

Estradiol may interact with several medicines, requiring careful management.

Major Interactions (Avoid): - Combined oral contraceptives: increased risk of thromboembolism. - Anticoagulants (e.g., warfarin): potential enhancement of anticoagulant effect. - Selective estrogen receptor modulators (SERMs): antagonistic hormonal action.

Moderate Interactions (Monitor Closely): - CYP3A4 inhibitors (e.g., ketoconazole): may raise estradiol plasma levels. - CYP3A4 inducers (e.g., rifampin): may lower estradiol plasma levels. - Thyroid hormone therapy: may require dose adjustment of thyroid medication.
