About Dydrogesterone
Indications of Dydrogesterone
Dydrogesterone is a synthetic, orally active progestogen (a "retroprogesterone") used in a range of gynecological and obstetric conditions related to progesterone deficiency. Its indications can be grouped by strength of evidence and regulatory/guideline support as follows:
Established / widely approved uses
- Dysfunctional uterine bleeding — to control acute episodes and to prevent recurrence.
- Secondary amenorrhea — typically given together with an estrogen.
- Irregular menstrual cycles due to progesterone deficiency.
- Endometriosis — to suppress ectopic endometrial tissue activity.
- Premenstrual syndrome (PMS) and dysmenorrhea associated with luteal insufficiency.
- Progestogen component of hormone replacement therapy (HRT) — combined with estrogen to protect the endometrium from unopposed estrogen stimulation in non-hysterectomised women.
Guideline-supported obstetric uses (regional variation in evidence and endorsement)
- Threatened miscarriage — used under medical supervision in women with a viable pregnancy and clinical signs of threatened miscarriage; several national obstetric guidelines and regulatory labels in Asia, Europe and elsewhere support this use, although evidence quality is debated and practice varies by country.
- Recurrent (habitual) miscarriage — used in women with a history of three or more consecutive miscarriages, generally started before conception or in early pregnancy and continued under specialist supervision.
Adjunct / fertility-related use
- Luteal phase support / infertility due to luteal insufficiency — as an adjunct in the management of infertility associated with inadequate luteal progesterone production, sometimes as part of assisted reproduction protocols.
Note: Dydrogesterone is not approved by the US FDA and is not marketed in the United States; the uses above reflect labeling and guideline support in countries (including Bangladesh) where it is registered and prescribed. Any use should be individualized and supervised by a qualified physician.
Dosage & Administration of Dydrogesterone
The dose and duration of Dydrogesterone depend on the indication being treated and must be individualized by the prescribing physician. Representative adult dosing regimens used in practice are summarized below; local product labeling should be followed.
| Indication | Typical adult dose | Duration |
|---|---|---|
| Threatened miscarriage | 40 mg as a single dose, then 10 mg every 8 hours until symptoms resolve | Continue for about one week after symptoms subside; may be extended under specialist supervision |
| Recurrent (habitual) miscarriage | 10 mg twice daily | From before or early in pregnancy, continued up to around the 20th week under specialist supervision |
| Dysfunctional uterine bleeding (acute control) | 10 mg twice daily | 5–7 days |
| Dysfunctional uterine bleeding (prevention of recurrence) | 10 mg twice daily, days 11–25 of the cycle | Several cycles, reassessed periodically |
| Secondary amenorrhea | 10 mg twice daily, days 11–25 of the cycle, usually with an estrogen given days 1–25 | Several cycles |
| Endometriosis | 10 mg twice daily, continuously or from day 5–25 of the cycle | As directed, often several months |
| Premenstrual syndrome / dysmenorrhea | 10 mg twice daily, days 11–25 (PMS) or days 5–25 (dysmenorrhea) of the cycle | Several cycles |
| Infertility due to luteal insufficiency | 10 mg once daily, days 14–25 of the cycle | At least 6 consecutive cycles; continued into early pregnancy if conception occurs |
| Hormone replacement therapy (progestogen component) | 10 mg once daily for the last 12–14 days of the estrogen cycle (sequential regimen), or continuously as directed for continuous-combined regimens | As long as HRT is clinically indicated |
Tablets are taken orally, usually with water, with or without food, at approximately the same time(s) each day. See Administration for practical instructions and Use in Special Populations for hepatic/renal considerations.
Side Effects of Dydrogesterone
Dydrogesterone is generally well tolerated. Reported adverse effects include:
- Common: breast tenderness or pain, headache or migraine, nausea, breakthrough bleeding or spotting, and mood changes (including low mood or irritability).
- Less common: dizziness, abdominal discomfort, fluid retention, and menstrual irregularities.
- Rare: hypersensitivity reactions (rash, itching, swelling) and liver function abnormalities.
Patients should report persistent or severe side effects, unexpected vaginal bleeding, or signs of an allergic reaction to their physician promptly.
Contraindications of Dydrogesterone
Dydrogesterone is contraindicated in patients with:
- Known hypersensitivity to Dydrogesterone or any excipient of the formulation.
- Known or suspected progestogen-dependent malignancy (e.g., certain breast cancers), when used for non-pregnancy indications.
- Undiagnosed abnormal vaginal bleeding that has not been medically evaluated.
These are true absolute contraindications; additional cautions relevant to specific situations (such as history of thromboembolic disease or hepatic impairment) are discussed under Precautions and Warnings.
Frequently Asked Questions about Dydrogesterone
What is Dydrogesterone used for?
Dydrogesterone is a synthetic progestogen used to treat conditions caused by a lack of natural progesterone, including threatened and recurrent miscarriage, dysfunctional uterine bleeding, secondary amenorrhea, endometriosis, premenstrual syndrome, infertility due to luteal insufficiency, and as the progestogen component of hormone replacement therapy. Your physician will select the indication and regimen that applies to you.
Is it safe to take Dydrogesterone during pregnancy?
Dydrogesterone has a specific, established use in pregnancy for threatened and recurrent miscarriage, and is prescribed for these situations under direct medical supervision when the expected benefit outweighs potential risk. For any other reason, it should be used in pregnancy only if clearly necessary and only on your doctor's advice — never start or continue it in pregnancy without medical guidance.
Can I take Dydrogesterone while breastfeeding?
It is not fully established whether Dydrogesterone passes into breast milk in significant amounts. As a precaution, it should be used during breastfeeding only if your physician considers it necessary, after weighing the benefit to you against any possible effect on your baby.
What are the common side effects of Dydrogesterone?
The most commonly reported side effects of Dydrogesterone are breast tenderness, headache, nausea, breakthrough bleeding or spotting between periods, and mood changes. These are usually mild; contact your physician if they are severe, persistent, or accompanied by unexpected vaginal bleeding.
Who should not take Dydrogesterone?
Dydrogesterone should not be used by anyone with a known hypersensitivity to it or its ingredients, anyone with a known or suspected progestogen-dependent cancer (such as certain breast cancers) when used for non-pregnancy indications, or anyone with undiagnosed vaginal bleeding that has not yet been evaluated by a doctor.
What should I do if I miss a dose or take too much Dydrogesterone?
If you miss a dose of Dydrogesterone, take it as soon as you remember unless it is almost time for your next dose — in that case skip the missed dose and continue your normal schedule; do not double up. If you or someone else has taken too much Dydrogesterone, seek immediate medical attention or contact a poison control center rather than trying to manage it at home.
