SUBSTANCE
Dydrogesterone
Duphaston is a highly effective medication featuring dydrogesterone as its active ingredient, classified as a progesterone agonist (a vital female sex hormone). It plays a key role in reducing the risk of endometrial hyperplasia.
This medication is typically prescribed for various conditions, including:
- Irregular menstrual cycles
- Dysmenorrhea (painful periods)
- Endometriosis
- Infertility
When combined with estrogen, Duphaston can also effectively treat secondary amenorrhea (absence of menstrual periods for six months or more) and manage heavy or irregular bleeding.
PrecautionsDuphaston is contraindicated in certain situations, including:
- Individuals with allergies to dydrogesterone or similar medications. If you experience symptoms like skin rash, itching, redness, swelling, or difficulty breathing, seek medical assistance immediately.
- Those with deep vein thrombosis (blood vessel blockage).
- Patients with cancers dependent on progesterone or estrogen.
- Individuals experiencing unexplained bleeding.
- Patients with liver dysfunction; this medication may impact liver health, so contact your healthcare provider if you notice symptoms like right upper abdominal pain, loss of appetite, dark urine, or jaundice (yellowing of skin and eyes).
- People with depression.
- Patients with porphyria.
While using Duphaston, regular breast self-exams are recommended due to an increased breast cancer risk when combined with estrogen.
Use of Duphaston During Pregnancy and BreastfeedingDuphaston should only be used during pregnancy if specifically prescribed by a healthcare professional. It can pass into breast milk, so breastfeeding is not advised while taking Duphaston.
