What is Estragyn?
Estragyn vaginal cream is a topical medication containing the active ingredient estrone.
It’s used to treat certain symptoms (i.e., itching, burning, etc.), in and around the vagina, which is associated with lack of estrogen brought on by menopause.
It’s important to note that Estragyn cream is only indicated for use in women that have an intact uterus, unless it’s prescribed alongside progestin. Estragyn is only intended for short-term use.
For more resources, including a full list of the risks and benefits of Estragyn, please review the product monograph.
How does Estragyn work?
When a person enters menopause, estrogen production slows and then stops. Although this is a natural, universal experience, it can lead to a number of different, uncomfortable symptoms.
One of these symptoms is thinning of the vagina walls, which can lead to itching, burning sensations, or dryness.
Estrone, the active ingredient in Estragyn cream, works by contributing to the growth of epithelial cells of the vaginal wall. In turn, it improves the thickness and elasticity of the vaginal walls. This aids in lubrication, as well as reduces vaginal dryness and itchiness.
What is Estragyn used to treat?
Estragyn’s primary indicated use is as a treatment for certain symptoms associated with menopause, including:
- Vaginal dryness
- Itchiness
- Burning sensations
It’s important to note that Estragyn is only indicated for use in women that have an intact uterus, and this medication should only be taken under regular supervision of your healthcare practitioner.
This includes a follow-up visit with your prescriber within 3-6 months of starting your Estragyn treatments.
Due to the fact that this medication is only recommended for short-term use, it’s important to also discuss the risks vs benefits of taking Estragyn cream with your practitioner, before starting Estragyn.
How do you take Estragyn?
Dosing Estragyn cream can range from 0.5g to 4g daily, depending on your practitioner’s recommendation. Estragyn is administered intravaginally.
If you’ve been wondering how to use Estragyn cream, it’s recommended for use cyclically on a schedule of 3 weeks on, 1 week off. It’s always recommended to use the lowest dosage possible to control symptoms, and discontinue use as soon as is appropriate.
This is part of the reason that regular check-ups with your practitioner are suggested, so that you can revisit how effective the medication is working for you, and whether you need to continue with Estragyn treatments.
