Estriol

Estriol is a natural estrogen hormone. Estriol binds to estrogen receptors in target cells, leading to the activation or inhibition of specific genes. It exerts its effects on various tissues, including the female reproductive system, breast tissue, and other estrogen-sensitive organs.

 

  • Estriol is indicated for the treatment of moderate to severe symptoms of vulvar and vaginal atrophy due to menopause.
  • It is used to relieve symptoms such as vaginal dryness, itching, burning, and discomfort during sexual intercourse.

 

  • The dosage of Estriol may vary depending on the individual and the severity of symptoms.
  • It is available in different forms, including creams, vaginal suppositories, and tablets.
  • The healthcare provider will determine the appropriate dosage and administration method for each patient.
  • It is important to follow the prescribed dosage and administration instructions provided by the healthcare provider.
