CARYON(Dydrogesterone)
CARYON(Dydrogesterone)
Therapeutic Group: Synthetic Progestogen
Presentation
Caryonâ„¢: Each tablet contains Dydrogesterone BP 10 mg.
Description
Dydrogesterone is an orally active, synthetic progestogen which produces a complete secretory endometrium in an oestrogen-primed uterus. At therapeutic levels, dydrogesterone has no contraceptive effect as it does not inhibit or interfere with ovulation or the corpus luteum. Furthermore, dydrogesterone is non-androgenic, non-estrogenic, non-corticoid, non-anabolic and is not excreted as pregnanediol. Dydrogesterone helps to regulate the healthy growth and normal shedding of the uterus lining.
Indications
Progesterone Deficiencies: Caryon is indicated for the treatement of Dysmenorrhoea, endometriosis, secondary amenorrhoea, irregular cycles, dysfunctional uterine bleeding, pre-menstrual syndrome, threatened and habitual abortion associated with proven progesterone deficiency and infertility due to luteal insufficiency.
Hormone Replacement therapy: Caryon is indicated for hormone replacement therapy in women with disorders due to naturally or surgically induced menopause in women with an intact uterus.
Dosage & Administration
Always take Caryon as your doctor has prescribed. If you forget to take your tablet(s), do not make a double dose to compensate for it.

Threatened abortion: Take four tablets at once, then one tablet every eight hours until symptoms abate.
Irregular cycles: Take one tablet daily from day 11 to day 25 of the cycle.

Hormone Replacement Therapy
• In combination with continuous estrogen threrapy, take one tablet daily for 14 consecutive days of a 28 days cycle.
• In combination with cyclical estrogen therapy, take one tablet daily during the last 12 to 14 days of estrogen therapy.
• If endometrial biopsies or ultrasound reveal inadequate progestational response, 20 mg (2 tablets) dydrogesterone should be prescribed
Caryon is not recommended for use in children below age 18 due to insufficient data on safety and efficacy.
Side Effects
The most commonly reported adverse drug reactions of patients treated with dydrogesterone are headache, nausea, menstrual disorders and breast pain/tenderness.
Precautions
Before initiating dydrogesterone treatment for abnormal bleeding the etiology for the bleeding should be clarified. Breakthrough bleeding and spotting may occur during the first months of treatment. If breakthrough bleeding or spotting appears after some time on therapy, or continues after treatment has been discontinued, the reason should be investigated, which may include endometrial biopsy to exclude endometrial malignancy.
If one of the following disorders occurs during use for the first time or gets worse, stopping the treatment should be considered.
• Severe headache, migraine or symptoms that may indicate cerebral ischemia.
• Marked increase in blood pressure.
• Occurrence of venous thromboembolism (VTE)
In cases of habitual or threatened abortion, the viability of the foetus should be ascertained. It is also necessary to monitor during treatment whether the pregnancy is still progressing and whether the embryo is still alive.
Patients with a history of depression must be carefully monitored; if severe depression recurs, treatment with dydrogesterone must be stopped
Use in Pregnancy & Lactation
Pregnancy: There were no harmful effects found in patients using dydrogesterone during pregnancy.
Lactation: No data exist on excretion of dydrogesterone in mother’s milk. Experience with other progestogens indicates that progestogens and the metabolites pass to mother’s milk in small quantities. Therefore, dydrogesterone should not be used during the lactation period.
Use in Children
There is no relevant use of dydrogesterone in children. The safety and efficacy of dydrogesterone in adolescents has not been established.
Drug Interaction
Drugs that induce CYP enzymes such as anti-convulsants (e.g., phenobarbital, phenytoin, carbamazepine), anti-infectives (e.g., rifampicin, rifabutin, nevirapine, efavirenz) and herbal preparations containing St John’s wort, valerian root, sage or gingko bilboba may lead to a decreased effect of Dydrogesterone and its active metabolite dihydrodydrogesterone (DHD).
Over Dose
Dydrogesterone was well tolerated after oral dosing (maximum daily dose is 360 mg). No reports of ill-effects from overdose have been recorded. If a large overdose is discovered within two or three hours and treatment seems desirable, gastric lavage is recommended. There are no specific antidotes and treatment should be symptomatic.
Storage
Do not store above 30ËšC. Keep in a dry place away from light and out of reach of children.
