What Is Phexxi?
Phexxi, now called Phexx, is the first and only hormone-free prescription birth control gel used on demand before sex. Unlike daily pills or long-term devices, Phexx is used only when needed, offering a flexible option for women exploring non-hormonal contraception.
This guide explains what Phexxi is, how it works, who it may suit, and how to get started.
Who Is It For?
Phexxi is an on-demand birth control method used right before intercourse. It works by maintaining vaginal pH in a way that makes it harder for sperm to move toward an egg.
This mechanism helps reduce the chances of pregnancy without using hormones.
Here is how Phexx works in practice:
- It is inserted into the vagina using a prefilled applicator
- It can be used up to 1 hour before intercourse
- It starts working immediately after insertion
- It does not work if used after sex
- A new dose is required before each act of vaginal sex
Because Phexx is used only when needed, it may appeal to women who prefer flexibility over daily or long-term contraception.
Many women consider Phexx because:
- There is no daily pill to remember
- There is no long-term device
- It is used only when needed
- It is a hormone-free prescription option
This format offers a different approach compared to traditional birth control methods.



Who Is It For?
Phexxi may be a good option for women who want more flexibility and control over their contraception.
It may appeal to women looking for:
- A hormone-free birth control option
- An alternative to daily birth control pills
- A non-permanent option instead of a long-term device
- More flexibility around when birth control is used
- A prescription method used right before sex
However, Phexxi is not right for everyone. Women with a history of recurrent urinary tract infections or certain urinary tract abnormalities may need to avoid it.
Before prescribing Phexx, a licensed Miley Health clinician reviews each patient’s consultation and medical history. This helps determine whether Phexx is appropriate for individual needs
