Last updated on November 22nd, 2021

Duphaston (dydrogesterone)

Generic name: Duphaston

Brand names: Diphaston, Dufaston, Duvaron, Dydrogesterona, Gestatron, Gynorest, Hydrogesterone, Isopregnenone, Prodel, Retrone

What is Duphaston (dydrogesterone) used for?

Duphaston treats conditions where there is a lack of the female hormone progesterone. It is used for:

  • restoring bleeding in the absence of menstrual periods
  • controlling irregular bleeding which is due to hormonal imbalance
  • the treatment of endometriosis, which is a disease where fragments of the lining of the uterus grow outside the womb in the pelvic cavity
  • painful periods which do not have any specific cause such as fibroids or infection
  • a supplement for menopausal women who are taking hormone replacement therapy (HRT), in which it helps to protect the uterus

Duphaston is an artificial hormone similar to human progesterone. It belongs to a group of hormones called progestogens.
Duphaston has been approved for the uses listed above. Duphaston may also be used for other purposes prescribed by your medical assistant and not listed above.
Duphaston is not addictive.

When shouldn’t Duphaston (dydrogesterone) be used?

Do not use oestrogens, with or without a progestogen to prevent heart attacks, stroke or dementia.
A study called the Women’s Health Initiative indicated increased risk of heart attack, stroke, breast cancer, and blood clots in the legs or lungs in females receiving treatment with a product containing conjugated oestrogens 0. 625 mg and the progestogen medoxyprogesterone acetate (MPA). The researchers stopped the study after 5 years when it was determined the risks were greater than the benefits in this group.

The Women’s Health Initiative Memory Study indicated increased risk of dementia in women aged 65-79 years taking conjugated oestrogens and MPA. There are no comparable data currently available for other doses of conjugated oestrogens and MPA or other combinations of oestrogens and progestogens. Therefore, you should assume the risks will be similar for other medications containing oestrogen and progestogen combinations.

Talk regularly with your medical assistant about whether you still need treatment with Duphaston.
Treatment with oestrogens, with or without progestogens should be used at the lowest effective dose and for the shortest period of time.

What should you know before taking Duphaston (dydrogesterone)?

When you must not take it:

Hormone replacement therapy (HRT) should only be used if you have been fully informed of the risks.
The decision to use HRT should be based on your particular needs and health, and made after a careful medical evaluation.

Do not take Duphaston:

  • if you have any blood clotting problems, or have had a stroke or a heart attack
  • if you have liver or gall bladder disease
  • if you have ever had jaundice (yellowing of the skin or eyes), which can occur with an intense generalised itching during pregnancy, or run in families
  • if you have, or are suspected to have, cancer of the breast or genitals, or some form of oestrogen (female hormone) dependent cancer

  • if you have unusual vaginal bleeding that has not been seen by a doctor

  • if you have ever had herpes during pregnancy
  • if you have had a certain type of miscarriage known as missed abortion
  • if you are breastfeeding. Duphaston passes into breast milk and therefore there is a possibility that the breast-fed baby may be affected.

    And swollen face or neck.

If you have not told your medical assistant about any of the above, tell them before you start taking Duphaston.
