Side Effects: The adverse effects of this product were most commonly reported in patients who were treated with dydrogesterone during clinical trials into indications without the use of oestrogen, such as metrorrhagia, painful, sensitive breasts, and migraine/headache. The following adverse effects, with the frequencies indicated, were observed during clinical trials with dydrogesterone (n=3,483) for indications without the use of oestrogen therapy.
Contraindications:
- Vaginal bleeding, where the cause has not been established.
- Presence of serious liver disorders, or serious liver disorders in the medical history, until the liver function values have returned to normal.

- Known or suspected sex hormone-dependent malignancies.
Special warnings and precautions for use: Before starting treatment with dydrogesterone because of dysfunctional uterine bleeding an organic cause should be excluded. Breakthrough bleeding and spotting may occur during the first months of treatment. If breakthrough bleeding and spotting continue to occur when treatment has already been underway for some time, or continue when treatment is discontinued, the cause of this should be ascertained, if necessary by taking an endometrial biopsy to exclude malignancy of the endometrium. If one of the following disorders occurs during use for the first time or gets worse, stopping the treatment should be considered:
- exceptionally severe headache, migraine or symptoms that may indicate cerebral ischemia.
- marked increase in blood pressure.
- occurrence of venous thromboembolism.
Fertility, pregnancy and lactation:
Pregnancy: It is estimated that over 9 million women have already been exposed to dydrogesterone during pregnancy. To date there were no indications that the use of dydrogesterone during pregnancy has a harmful effect. Clinical trials in which a limited number of women were treated with dydrogesterone in the first stage of pregnancy did not show that the risk is increased. Dydrogesterone may be administered during pregnancy if there is a clear indication for this.
Lactation: It is not known whether dydrogesterone is excreted in breast milk. No research has been done into the excretion of dydrogesterone in breast milk. Experiences with other progestogens indicate that progestogens and their metabolites are found in small quantities in breast milk. It is not known whether there is a risk for the child. Dydrogesterone should therefore not be used while breastfeeding.
Fertility: There are no data on the effect of dydrogesterone on fertility.
