Morning Vs Evening Dosing

Are you wondering whether to take Duphaston in the morning or evening?

Pick a consistent time each day that fits your existing routine to keep blood levels steady.

Take Duphaston (dydrogesterone) 10 mg tablets orally at the same hour daily for luteal support or cycle regulation.

If your prescriber orders twice-daily dosing, such as 10 mg twice daily for dysfunctional bleeding, split doses roughly 12 hours apart.

For fertility protocols, many patients set a morning alarm when they already take other meds and clinic instructions allow once-daily dosing.

Use a checklist to confirm daily intake: prescription, dose, time, and any side effects to report.

Keeping doses consistent reduces variability in progesterone exposure and helps clinics interpret bleeding patterns.

Taking With Or Without Meals

Dydrogesterone can be taken with or without food according to patient preference and tolerability.

If nausea or stomach upset occurs, take the tablet with a light meal to reduce gastrointestinal discomfort.

Store blister packs below 30°C and keep them dry away from direct heat and humidity.

Mark doses on a paper calendar or use a phone alarm to improve adherence.

• Tip: Keep the blister in its carton until use to protect from light and moisture.
• Tip: Use a weekly pill organizer only if you transfer the exact tablet and label the organizer clearly.
• Tip: Note start and stop dates on the calendar for cycle-based regimens.
• Tip: Carry prescription details in case a clinic asks during travel or follow-up.

Safety Priorities

Who Should Avoid It

Who should not take Duphaston is a common safety question from patients.

Do not use Duphaston if there is a known allergy to dydrogesterone or any tablet excipient.

Avoid the medicine in proven or suspected progestogen-dependent tumors and in active or severe liver disease.

Do not start treatment with unexplained vaginal bleeding until the cause is investigated.

Discuss any personal or strong family history of thromboembolism and severe depression with your prescriber before starting therapy.

Activities To Limit

There are no formal activity bans while taking dydrogesterone for most patients.

If dizziness, severe headache, or signs of clotting occur, stop exertion immediately and seek medical care.

For patients at risk of thromboembolism, avoid prolonged immobility and follow medical advice on travel or post-surgical periods.

Watch for sudden leg pain, swelling, chest pain, or breathlessness and treat them as emergencies.

• Checklist: Stop vigorous activity and rest if you experience new-onset severe headache or visual changes.
• Checklist: Seek urgent care for acute calf pain, breathlessness, or chest tightness.
• Checklist: Notify your clinician promptly about mood changes, new depressive symptoms, or ongoing severe fatigue.

Dosage & Adjustments

General Regimen

Patients and providers use dose regimens tailored to the indication and clinical protocol.

Follow prescriber instructions precisely and never self-adjust the regimen without consultation.

Special Cases

Severe hepatic impairment is a contraindication for use due to hepatic metabolism and safety concerns.

Pediatric prescribing is rare; consult a specialist if treatment is considered.

Elderly patients should be managed with the same progestogen precautions used for other agents.

In habitual abortion protocols, dydrogesterone may be continued through at least week 20 per clinician guidance.

• Missed Dose Checklist: Take the missed tablet as soon as you remember unless the next dose is near.
• Missed Dose Checklist: Do not double the next tablet to make up for a missed dose.
• Missed Dose Checklist: If multiple doses are missed, contact your clinic for advice.

Buying Guide

Pharmacy Sources

Where to source Duphaston depends on local registration and import rules for dydrogesterone.

Duphaston is prescription-only and available from licensed pharmacies in many European, Asian, and Middle Eastern markets.

Because Duphaston was discontinued in the UK and USA, US patients should consult specialists about legal alternatives or importation pathways.

In our online pharmacy, duphaston is available without a prescription, with discreet delivery to United States in 5-14 days.

Price Comparison

Pricing varies by country, brand, and whether clinic samples are provided; generics have limited global penetration.

Compare branded Duphaston prices at licensed pharmacies against any clinic-provided supply when assessing cost.

Buy only from verified pharmacy sites that request a prescription to reduce counterfeit risk.

• Checklist: Always verify pharmacy accreditation and look for secure payment and prescription upload.
• Checklist: Ask your clinic about patient-assistance programs or samples if cost is a concern.
• Checklist: Avoid pharmacies that ship without prescription verification or offer extremely low prices.

What’s Inside & How It Works

Ingredients Overview

The active ingredient is dydrogesterone (INN), formulated as a 10 mg oral tablet.

Currently, dydrogesterone is only marketed as oral tablets; no injectable, topical, or vaginal forms are available.

Ask your pharmacist about excipient lists if you have known tablet-component allergies.

Mechanism Basics

Dydrogesterone is a synthetic progestogen classified under ATC G03DB01.

It supports the luteal phase and stabilizes the endometrium without inhibiting ovulation at standard doses.

Dydrogesterone lacks significant androgenic, estrogenic, or glucocorticoid activity, which often reduces unwanted hormonal side effects.

• Point: Provides progestogenic activity to maintain endometrial stability.
• Point: Used in assisted reproductive technology for luteal support while preserving ovulation.
• Point: Long clinical history since 1961 supports its pharmacologic profile.

Main Indications

Approved Uses

Duphaston (dydrogesterone) is approved in many countries for a range of gynecologic indications.

All uses are prescription-only and should be supervised by a clinician.

Off-Label Uses

Clinicians may use dydrogesterone off-label for individualized luteal support or specific gynecologic situations.

Document the rationale and track outcomes over 3–6 cycles when using off-label regimens.

• Checklist: Ask the clinician to explain the expected benefits and monitoring plan for off-label use.
• Checklist: Request written instructions about duration, side effects, and when to stop therapy.
• Checklist: Keep a treatment diary to help clinicians assess response.

Interaction Warnings

Food Interactions

There are no major food interactions documented for dydrogesterone.

Patients can take it with or without meals depending on tolerability.

If alcohol increases fatigue or dizziness, avoid drinking while taking the medicine.

• Tip: Take with a light snack if nausea occurs.
• Tip: Maintain hydration and avoid heavy alcohol when adjusting to hormonal therapy.

Drug Conflicts

Certain drugs can reduce dydrogesterone exposure via enzyme induction or modify effects of co-administered medicines.

Provide your full medication and supplement list to your prescriber and pharmacist to check for interactions.
