Common use

Duphaston contains dydrogesterone, a synthetic progestogen that closely mirrors the molecular structure and pharmacological activity of naturally occurring progesterone. This well-tolerated hormone therapy medication is prescribed to restore hormonal balance when the body's own progesterone production is insufficient. Duphaston is widely used to treat a broad range of gynecological conditions including threatened miscarriage, habitual abortion, premenstrual syndrome (PMS), dysmenorrhea (painful periods), irregular menstruation, secondary amenorrhea (absence of periods), and dysfunctional uterine bleeding. For women experiencing fertility challenges, dydrogesterone provides essential progesterone support during the luteal phase to help maintain early pregnancy. Additionally, Duphaston plays an important role in managing endometriosis — a painful condition where tissue similar to the uterine lining grows outside the uterus. The medication works by stimulating the secretory phase in the endometrium, which significantly reduces the risk of endometrial hyperplasia and carcinogenesis that can develop due to unopposed estrogen exposure. Many patients choose to buy Duphaston online for its proven safety profile and effectiveness in hormone therapy. Duphaston generic versions containing the same dydrogesterone active ingredient offer an equally effective and more affordable treatment option for menstrual disorders and progesterone support.



Dosage and direction

Each gynecological condition requires a specific treatment protocol and individualized dose schedule when taking this progestogen. Always follow the instructions provided by your doctor carefully. For the treatment of endometriosis, the typical dose is 10 mg of Duphaston taken two or three times daily from the 5th to the 25th day of your menstrual cycle. For fertility support and treatment of infertility related to luteal insufficiency, take 10 mg of dydrogesterone once daily from the 14th to the 25th day of your cycle. This progesterone support regimen should be continued without interruption for a minimum of three to six consecutive cycles, and may be extended further based on your doctor's assessment. For threatened miscarriage, your doctor may prescribe an initial loading dose of 40 mg followed by 10 mg every 8 hours until symptoms resolve. For premenstrual syndrome, the recommended dose is typically 10 mg twice daily from the 11th to the 25th day of your cycle. The dosage for menstrual disorder treatment may vary depending on the specific condition being addressed. Contact your doctor to discuss all details of your individual hormone therapy plan and ensure optimal treatment outcomes.



Precautions

Before starting treatment with Duphaston, inform your doctor if you are pregnant or breastfeeding, as this information is essential for safe prescribing. If you are using dydrogesterone as part of hormone replacement therapy (HRT), your doctor should conduct a thorough general medical examination before initiating treatment, including a comprehensive pelvic examination to rule out any contraindicated conditions. Your doctor may recommend regular mammogram screenings while you are receiving this progestogen, particularly if you have risk factors for breast conditions. Report any unusual vaginal bleeding promptly, as it may require investigation. Patients with a history of depression should be carefully monitored during treatment, as hormonal changes may affect mood. If you experience signs of a thromboembolic disorder (such as painful swelling of the legs, sudden chest pain, or difficulty breathing), seek immediate medical attention and discontinue the medication until your doctor advises otherwise.



Contraindications

Duphaston is contraindicated in individuals with known hypersensitivity to dydrogesterone or any of the excipients in the formulation. This medication must not be used by patients diagnosed with Dubin-Johnson syndrome (a rare inherited condition characterized by elevated conjugated bilirubin without significant changes in liver enzyme levels) or Rotor syndrome (a benign autosomal recessive bilirubin disorder). Patients with undiagnosed vaginal bleeding, known or suspected progesterone-dependent neoplasms, severe liver disease or active liver tumors, and those with a history of or current thromboembolic disorders should not buy dydrogesterone without first consulting a qualified healthcare professional. If you have any of these conditions, your doctor will recommend alternative treatment approaches for your menstrual disorder or other gynecological needs.



Side effects

The most frequently reported adverse reactions during Duphaston therapy include headache, nausea, dizziness, abdominal bloating, and skin reactions such as rash and itching. Some women may experience breast tenderness or swelling, which is a common response to progestogen medications. Menstrual spotting or breakthrough bleeding between periods may occur, particularly during the initial cycles of treatment. Less common side effects include changes in libido, mood alterations, weight fluctuations, and gastrointestinal disturbances. In rare cases, dydrogesterone may contribute to fluid retention or mild edema. Serious adverse reactions are uncommon but may include signs of liver dysfunction (jaundice, dark urine, persistent fatigue) or thromboembolic events. If you experience any severe or persistent symptoms during hormone therapy, contact your healthcare provider promptly for evaluation. Most mild side effects tend to resolve as your body adjusts to the progesterone support provided by the medication.



Drug interaction

Inducers of microsomal liver enzymes, such as phenobarbital, rifampicin, phenytoin, and carbamazepine, may accelerate the hepatic metabolism of Duphaston and consequently weaken its therapeutic effect. If you are taking any of these medications concurrently, your doctor may need to adjust your dydrogesterone dosage accordingly. Inform your healthcare provider about all prescribed and over-the-counter medications, herbal supplements (particularly St. John's wort, which is a potent enzyme inducer), vitamins, and any other products you are currently using. Certain antifungal medications and antibiotics may also influence the way this progestogen is processed by the body. Always discuss potential interactions before starting any new medication while on Duphaston therapy to ensure continued effectiveness of your hormone therapy regimen.



Missed dose

If you forgot to take a dose of Duphaston, take it as soon as you remember, provided it is not too close to the time of your next scheduled dose. If it is nearly time for your next dose, skip the missed one and continue with your regular dosing schedule. Do not take a double dose to make up for the one you missed, as this will not improve effectiveness and may increase the risk of side effects. Consistent adherence to your prescribed schedule is important for maintaining adequate progesterone support, especially if you are using dydrogesterone for threatened miscarriage or fertility treatment. Contact your doctor if you have questions about how to proceed after missing a dose.



Overdose

There is limited information available regarding dydrogesterone overdose. No serious adverse effects have been reported following acute ingestion of large doses of Duphaston. Symptoms of overdose may potentially include nausea, vomiting, and drowsiness. If you suspect an overdose, seek immediate medical attention. Treatment is generally supportive and symptomatic, as there is no specific antidote for this progestogen. Your doctor may recommend gastric lavage if ingestion was recent and monitoring of vital signs.



Storage

Store Duphaston at room temperature between 20-25 C (68-77 F) in its original packaging to protect from light and moisture. Keep the medication away from direct heat and sunlight, which may degrade the active ingredient dydrogesterone. Do not store in a bathroom or other humid environments. Keep this and all medications out of reach of children and pets. Do not use tablets that have passed their expiration date or show visible signs of deterioration.
