Substitute Hormonal Therapy (HRT) of estrogen deficiency symptoms in postmenopausal women.

The experience of this treatment in women over 65 is limited.

Dosage DELIDOSE 1 mg Transdermal Gel Box of 28 Sachets-dose


DELIDOSE is a gel for cutaneous application. DELIDOSE can be used in continuous or batch treatment (cyclically).

The usual starting dose is 1.0 mg estradiol (1.0 g gel) per day, but the initial dose may be adjusted according to the severity of the clinical symptoms.

After 2 to 3 cycles of treatment, the dosage may be adjusted depending on the clinical response. It must be between 0.5 and 1.5 mg of estradiol per day (ie between 0.5 and 1.5 g of gel per day).

To start or continue treatment for the indication of postmenopausal symptoms, the minimum effective dose should be used for the shortest possible duration (see Warnings and Precautions ).

In non-hysterectomized patients, it is recommended to add a progestogen to DELIDOSE at least 12 to 14 days per month / per 28-day cycle to prevent the development of estrogen-induced endometrial hyperplasia (see also section 4.4). Warnings and precautions for use ).

In hysterectomized women, except for a history of endometriosis, it is not recommended to combine a progestin.

In women who do not take HRT, as well as in a continuous combined HRT relay, DELIDOSE treatment can be started on any day. In relaying a continuous sequential THS, the treatment must be started the day after the end of the last previous treatment cycle.

If the patient has forgotten to apply a dose, the missed dose should be applied as soon as possible within 12 hours of the usual time of application. Beyond 12 hours, the dose will not be applied and treatment will continue normally by applying the dose the following day. Forgetting a dose may encourage the occurrence of spotting and bleeding.

There is no relevant indication for the use of DELIDOSE in children.

Administration mode

Apply on clean and dry skin.

DELIDOSE is applied once a day, alternately on the lower abdomen or on the right or left thigh. The application surface must be 1 to 2 times the surface of a hand.

DELIDOSE should not be applied to breasts, face or irritated skin.

After application, let the gel dry for a few minutes and do not put the skin in contact with water for one hour. Avoid any contact of the gel with the eyes. Wash hands after application.

1 ) These are unique cases reported in clinical studies. Since these studies were conducted on a small population (n = 611), it is not possible to determine if these effects are infrequent or rare.

Other adverse effects reported following estrogen-progestin therapy:

· Benign and malignant estrogen-dependent tumors, eg endometrial cancer.

· Venous thromboembolic disease (deep vein thrombosis of the pelvis or lower extremities, pulmonary embolism), more common in women on HRT than non-users. For more information, see Contraindications section "Contraindications" and section Warnings and precautions for use "Special warnings and precautions for use".

· Myocardial infarction and stroke.

· Biliary disorders.

· Skin and subcutaneous tissue disorders: chloasma, erythema multiforme, erythema nodosum, vascular purpura.

· Likely dementia after age 65 (see Warnings and Precautions section ).

Breast cancer risk

· In women taking combined estrogen-progestin for more than 5 years, an increased risk of being diagnosed with breast cancer increased by 2 times has been reported.

· In women taking estrogen alone, the risk is significantly less than in estrogen-progestogen combination therapy.

· The level of risk depends on the duration of HRT use (see Warnings and Precautions section ).

· The results of a large randomized placebo-controlled study (WHI study) as well as a large epidemiological study (MWS) are presented in the tables below:

‡ When the analysis was restricted to women who did not use HRT prior to the study, there was no apparent increase in risk during the first 5 years of treatment. After 5 years, the risk has increased compared to non-users.

Risk of endometrial cancer

Menopausal women not hysterectomized:

The risk of endometrial cancer is approximately 5 per 1000 women who are not hysterectomized and do not use HRT.

In non-hysterectomized women, the use of estrogen-only HRT is not recommended as it increases the risk of endometrial cancer (see Warnings and Precautions section ).

In epidemiological studies, according to duration of use and dose of estrogen alone, the increase in the risk of endometrial cancer varies from 5 to 55 new cases diagnosed in 1000 women, whose age is understood between 50 and 65 years old.

The combination of a progestin with estrogen alone for at least 12 days per cycle can prevent this increased risk. In the Million Women Study (MWS), the use of combined HRT for 5 years (sequential or continuous) did not increase the risk of endometrial cancer (RR 1.0 (0.8 - 1.2)).

Ovarian cancer

Long-term use of estrogen alone and combined (estrogen-progestin) HRT is associated with a slight increase in the risk of ovarian cancer. In the MWS study, 5 years of HRT result in 1 new case for 2500 users.

Risk of venous thromboembolic accident

HRT is associated with a 1.3 to 3 increase in the relative risk of developing a venous thromboembolic event, such as deep vein thrombosis or pulmonary embolism.

The occurrence of such an event is more likely during the first year of hormonal treatment (see Warnings and Precautions ).

The results of the WHI studies are presented in the table below:

Risk of coronary heart disease

· The risk of coronary heart disease is slightly increased in users of estrogen-progestogen combined HRT over 60 years of age (see Warnings and Precautions section ).

Risk of stroke

· The use of estrogen alone and combined (estrogen-progestin) therapy is associated with a 1.5-fold increase in the relative risk of ischemic stroke. The risk of haemorrhagic stroke is not increased during the use of HRT.

· Relative risk does not depend on age and duration of use, but since the absolute risk (baseline) is highly age-dependent, the overall risk of an accident for women who use HRT will increase with age, see Warnings and Precautions section .

Reporting of suspected adverse reactions

The reporting of suspected adverse reactions after authorization of the drug is important. It allows continuous monitoring of the benefit / risk ratio of the drug. Healthcare professionals declare any suspected adverse reaction via the national reporting system: National Agency for the Safety of Medicines and Health Products (Ansm) and the network of Regional Pharmacovigilance Centers - Website:
