Duphaston: UK Status and Risks
Duphaston is not a UK-licensed product in the United Kingdom. Some sellers may still list it, but no MHRA review of its safety or effectiveness covers it.
Talk to a doctor or pharmacist before using any unlicensed product, and treat bold marketing claims about it with caution. A missing or unclear UK licensing status is itself worth asking about.
Not UK-licensed. This medicine is not supplied through UK-registered pharmacies.
Sellers list the active ingredient as dydrogesterone. The MHRA has not assessed what these products actually contain.
The MHRA warns that medicines sold outside registered pharmacies can be counterfeit, contaminated, or contain the wrong amount of active ingredient. Buy prescription-only medicines from a pharmacy registered in the UK.

About Duphaston
Duphaston is not a licensed medicine in the United Kingdom and cannot legally be sold there as a medicine. Its marketing material does not identify an active ingredient, a medicine class, or a claimed strength.
This limits what can be said about its effects and safety. A doctor or pharmacist can discuss treatment options and assess any packaging before use.
Claimed strengths are manufacturer claims, but no strength or dosage form is listed for Duphaston. There is no stated strength to compare with a licensed equivalent, and none is named here.
The product name does not establish the amount of any active ingredient. This section does not establish a dose or a treatment schedule.
How Duphaston works
The active ingredient and pharmacological class of Duphaston are not identified in its marketing material. A reliable explanation of how it works cannot therefore be given. Medicines act in different ways, depending on their ingredients, and a product name alone does not establish a mechanism.
Assigning this product a hormone effect or any other specific action would require confirmed ingredient details. A pharmacist can assess the packaging and discuss what can be established about its contents.
What Duphaston is used for
No marketed treatment use is specified for Duphaston in its marketing material. It is therefore not possible to describe a claimed benefit or explain which condition the product is intended to help with.
The product name alone does not establish its ingredients, intended use, or suitability for a particular person. Any treatment claims seen in advertising should be discussed with a doctor or pharmacist rather than treated as evidence that the product is effective.
Key warnings
- Not licensed as a medicine in the United Kingdom; its contents and quality have not been independently verified.
- The active ingredient and strength are not identified, so ingredient-specific risks cannot be assessed.
- A product name alone does not establish whether it is suitable alongside existing treatment.
- A doctor or pharmacist should assess the packaging before any treatment decision.
Main interactions
- Interactions with prescription medicines cannot be assessed until the active ingredient is confirmed.
- Interactions with medicines bought from a pharmacy cannot be assessed until the contents are known.
- Possible interactions with herbal remedies and supplements need assessment by a pharmacist.
Storage
No storage conditions or dosage form are listed for Duphaston. Keep medicines out of the reach of children. A pharmacist can advise on storage once the packaging and contents have been assessed.
Missed dose
No product-specific missed-dose guidance is stated for Duphaston. Its active ingredient and medicine class are not identified, so general class guidance cannot safely be applied. A doctor or pharmacist can assess the product and explain how any interruption in treatment should be managed.
Pregnancy and breastfeeding
The marketing material does not specify pregnancy or breastfeeding data for Duphaston. Its active ingredient and medicine class are not identified, so their effects during pregnancy or breastfeeding cannot be assessed. Discuss the product with a doctor or pharmacist before making a treatment decision.
