ACTIVE INGREDIENT
Dydrogesterone
Duphaston is a highly effective medication featuring dydrogesterone as its active ingredient. As a classified progesterone agonist, it plays a crucial role in reducing the risk of endometrial hyperplasia.
This versatile medication is commonly prescribed for various conditions, including:
- Irregular menstrual cycles
- Dysmenorrhea (painful menstrual periods)
- Endometriosis
- Infertility
When combined with estrogen, Duphaston can also be beneficial in treating secondary amenorrhea (the absence of menstrual periods for six months or longer) and is effective in managing heavy and irregular bleeding.
Important PrecautionsBefore using Duphaston, be aware of the following contraindications:
- Allergic reactions to dydrogesterone or similar medications. If you notice symptoms such as:
- skin rash,
- itchy skin,
- redness,
- swelling, or difficulty breathing, seek immediate medical assistance.
- Individuals with deep vein thrombosis (a blockage in veins).
- Patients with cancers that are influenced by progesterone or estrogen.
- Unexplained bleeding issues.
- Those with liver dysfunction, as Duphaston may impact liver health. If you experience symptoms like:
- pain in the upper right abdomen,
- loss of appetite,
- dark urine,
- jaundice (yellowing of skin and eyes), please consult your doctor promptly.
- Individuals suffering from depression.
- Patients with porphyria.
Regular breast self-exams are advised while using this medication due to an increased risk of breast cancer when combined with estrogen.
Duphaston Use During Pregnancy and BreastfeedingDuphaston is not recommended during pregnancy unless specifically prescribed by a healthcare professional. Additionally, this medication can be passed into breast milk, making breastfeeding inadvisable while taking Duphaston.

Take the tablet whole with a glass of water; do not crush or chew it.
