Introduction
Brand name: Hydroston
Manufacturer: Astemax Biotech Pvt. Ltd.
Composition: Dydrogesterone 10 mg tablet
Hydroston is a synthetic progestogen (progesterone analog) tablet containing dydrogesterone 10 mg, used for various gynaecological and hormonal indications. Dydrogesterone behaves like natural progesterone and supports endometrial transformation, luteal‑phase support, and menstrual‑cycle regulation, with relatively fewer androgenic or glucocorticoid effects compared with older progestins.
Key indications
Luteal‑phase defect, threatened miscarriage, and recurrent pregnancy loss (as part of progesterone support).
Endometriosis, dysmenorrhoea (painful periods), and abnormal uterine bleeding.
Hormone‑replacement therapy (HRT) and menstrual‑cycle regulation in women needing progesterone supplementation.
Dosage and precautions
Usual dose ranges from 10 mg once or twice daily, depending on indication (e.g., luteal support, abnormal uterine bleeding, endometriosis); exact regimen must follow local prescribing information and physician guidance.
