Dosage

Estriol (Oral) dosage

It is important that the total daily dose is taken at one time. It may be taken with or without food. Atropy of the lower urogenital tract: 4-8 mg/day for the first weeks, followed by a gradual reduction, based on relief of symptoms, until a maintenance dosage (e.g. 1-2 mg/day) is reached. Pre and postoperative therapy in postmenopausal women undergoing vaginal surgery: 4-8 mg/day in the 2 weeks before surgery; 1-2 mg/day in the 2 weeks after surgery. Climacteric complaints such as hot flushes and night sweating: 4-8 mg/day during the first weeks, followed by a gradual reduction. For maintenance therapy the lowest effective dosage should be used. A diagnostic aid in case of a doubtful atrophic cervical smear: 2-4 mg/day for 7 days before taking the next smear. Infertility due to cervical hostility: In general 1-2 mg/day on days 6-15 of the menstrual cycle. However, for some patients dosages as low as 1 mg/day are sufficient, whereas others may need up to 8 mg/day. Therefore, the dosage should be increased each month until an optimal effect on the cervical mucus is obtained.

Side Effects

Interaction

There are strong indications that estrogens, estriol included, can increase the pharmacologic effects of certain corticosteroids. If necessary, the dosage of the corticosteroid should be reduced. There are also some indications, mainly obtained with other estrogens or oral contraceptives, that concurrent use of estriol with activated charcoal, barbiturates, hydantoins and rifampicin may possibly decrease the effectiveness of estriol.

Pregnancy & Breastfeeding use

Estriol is contraindicated during pregnancy. Use Estriol in breastfeeding women only if really needed, as estriol is excreted in the milk and it may decrease the quality and quantity of the milk production.

Contraindication

Contraindicated in pregnancy, known or suspected estrogen-dependent tumours, undiagnosed vaginal bleeding, untreated endometrial hyperplasia, known or suspected breast cancer.

Acute Overdose

Symptoms that may occur in the case of an acute overdosage are nausea, vomiting and possibly withdrawal bleeding in females. No specific antidote is known. If necessary, a symptomatic treatment should be instituted.
