ESTRAVAL DEPOT (Generic Progynon Depot)
$ 36.00 – $ 82.50
Estraval depot injection contains oestradiol valerate (generic progynon depot), which is a synthetic form of naturally occurring oestradiol. Oestradiol is the most important form of the female sexual hormone estrogen.
It is a steroid hormone produced by the ovaries which are responsible for secondary sexual characteristics in females, such as the development of breast and also the regulation of the menstrual cycle. Estraval depot injection (Generic Progynon Depot) is primarily given as a hormone replacement therapy (HRT) in order to substitute any lack of oestrogen production by ovaries. It is usually advised during menopause or after surgical removal of ovaries to reduce the menopausal symptoms occurring by estrogen deficiency. It is also used in men for the treatment of prostate cancer.
Components and mechanism of action
Estraval 10mg depot injection contains oestradiol valerate in a sterile oil solution. It is a long-acting estrogen preparation for intramuscular injection. Oestradiol acts as a precursor for 17β-oestradiol, which is a natural form of the female hormone estrogen. It acts on certain estrogen-receptor cells and thereby is responsible for maintaining secondary sexual characteristics in females. The vehicle oil base (peanut oil/arachis oil) aids in treating the manifestations of menopause.
- Hormone replacement therapy (HRT) to reduce menopausal symptoms like night sweats, hot flushes, vaginal dryness, sleeplessness, restlessness, mood swings, headache, lethargy and lack of concentration. It is used to substitute for lack of estrogen during menopause or following surgical removal of ovaries.
- Prevention of postmenopausal osteoporosis (bone loss) and thereby reduce the fracture risk.
- In case of advanced androgen-dependent prostate cancer, for symptomatic relief.
- As a part of transgender hormone treatment for male-to-female transsexuals, in order to stimulate the female secondary sexual characteristics. Oestradiol valerate gets converted into 17β-oestradiol, which is responsible for feminization in male-to-female transsexuals as a significant part of their sexual orientation reassignment program. Oestradiol promotes the development of female secondary sexual characteristics such as breast enlargement and metabolic changes through fat redistribution into feminine shape, as well as counters the effects of testosterone.
Directions to use
This medication is available in a 1ml vial containing 10mg oestradiol valerate. A syringe with 2cc(ml) capacity is attached to a 22-gauge needle and loaded with the contents of the vial. It is then injected with sterile precautions into the muscle (preferably at the upper outer area of gluteal muscles). The hormone blended with an oil base forms a depot within the injected muscle which allows for gradual release and absorption into the bloodstream.
The dosage is based on the medical condition as well as the treatment response, according to the physician’s prescription. The usual dose given is one vial injected regularly every 4 weeks. In the case of prostate cancer, this medication is given every 1 to 2 weeks. The treatment duration may last for several months. If a dose is missed, then it can be taken as soon as remembered.
If a missed dose is recalled during the time of the next dose, then it can be skipped. Avoid taking double doses. If there are too many missed doses, then the physician must be consulted for changes in the dosing schedule or a new schedule. Overdose may cause nausea, vomiting and vaginal bleeding. One must seek emergency medical attention if an overdose is suspected.
Vials are stored within their box until used, at room temperature (25°C). Avoid direct sunlight and moisture, and do not refrigerate. Do not store in the bathroom. Keep out of the reach of children and pets. Properly dispose of the item after usage.

Warnings and precautions
Before using this medication, a detailed medical history should be revealed to the physician. This drug is not advisable in the following conditions:
- family or past history of breast cancer, endometrial cancer or liver disease.
- history of allergy to oestradiol valerate or any other drugs
