Dydrogesterone 10mg Tablets

Product Introduction

Dydrogesterone 10mg is an oral progestogen used for selected conditions associated with insufficient progesterone activity, including menstrual-cycle disorders, endometriosis and luteal-phase support. It is also used with oestrogen in some hormone-replacement regimens to protect the uterine lining. The reason for treatment determines which days of the cycle it is taken.

How to use

Swallow the tablet with water, with or without food. Take doses at regular times on the specified cycle days; when more than one daily dose is needed, spread them through the day. A fertility or pregnancy-support schedule differs from a schedule used to regulate menstrual bleeding.

How it works

Dydrogesterone activates progesterone receptors. In an oestrogen-primed uterus it promotes a secretory endometrium, supporting the normal progesterone-dependent changes of the menstrual cycle and reducing excessive endometrial stimulation during oestrogen treatment.

Side effects

Headache or migraine, nausea, breast tenderness and changes in menstrual bleeding can occur. Jaundice, severe abdominal pain, or an allergic reaction with swelling or breathing difficulty needs prompt medical attention.

Important information

Unexplained vaginal bleeding should be investigated before hormonal treatment. Tell your doctor about liver disease, depression, porphyria or a known hormone-sensitive tumour. Medicines such as carbamazepine, phenytoin, rifampicin and St John's wort can reduce the hormone's effect. New or persistent unexpected bleeding during treatment needs assessment.
