Estriol
About Estriol
Estriol is used to relieve menopausal symptoms such as vaginal atrophy (vaginal dryness or irritation). It is used before/after vaginal surgery to help wound healing. Vaginal atrophy occurs due to a drop in the levels of oestrogen that naturally happens after menopause.
Estriol contains ‘estriol’, which works by replacing the oestrogen that is normally produced by the ovaries. Thus it provides relief from discomfort, dryness or irritation in the vagina.
In some cases, you may experience side effects such as itching, irritation of the skin around the vagina, swollen, tender, or painful breasts, headache, and nausea. Most of these side effects do not require medical attention and will resolve gradually over time. However, you are advised to talk to your doctor if the side effects persist or worsen.
Avoid using Estriol if you are pregnant, planning for pregnancy or breastfeeding. Stop using Estriol and consult a doctor if you notice jaundice, a large rise in blood pressure, migraine, if you become pregnant or if you notice any signs of a blood clot such as sudden chest pain, difficulty breathing, painful swelling and redness of the legs. Keep your doctor informed about your health condition and medicines to rule out any side effects.

Patients Concern
Disease/Condition Glossary
Vaginal atrophy: When women get older, the ovaries gradually produce less oestrogen; this happens at menopause or if the ovaries are removed before menopause. Vaginal atrophy occurs due to a drop in the levels of oestrogen that naturally happens after menopause. It is a condition in which the vaginal lining becomes thinner and drier, leading to itching, burning sensation, pain during sex, dryness, and itching in the vagina.

Estriol works by replacing the oestrogen, which is generally produced by the ovaries, thereby helping relieve discomfort in the vagina.
If you have premature menopause, the risks of using hormone replacement therapy might be different. Therefore, talk to your doctor if you have any concerns.
Estriol might result in bleeding or spotting. It is typically nothing to be concerned about. However, if you find them, visit your doctor since it might indicate that the endometrium has thickened.
