Can Vaginal estriol cream interact with other medicines or vaginal products?

Tell your prescribing physician about all prescription medicines, over-the-counter products, vitamins, and herbs you use before starting Vaginal estriol cream. Include hormone patches, pills, creams, vaginal rings, and birth control. Even a product used in the vagina needs a medication review.

It is especially important to discuss treatments for hormone-sensitive cancers, including aromatase inhibitors and tamoxifen. Whether vaginal estrogen is appropriate may require input from your cancer care team. Do not stop or adjust cancer treatment to use this cream.

Ask before combining estriol with vaginal moisturizers, lubricants, antifungal treatments, or other vaginal medicines. Using products together may change how they spread or cause added irritation. Your physician or pharmacist can tell you whether to separate applications and by how long.

Some cream bases may weaken latex condoms or diaphragms. The pharmacist can check the exact ingredients in your compounded formula. Do not assume all vaginal creams have the same compatibility. Vaginal estriol cream is not birth control and does not protect against sexually transmitted infections.
