More about Vaginal Gel (Phexxi)
Phexxi does not contain hormones, so it is considered safe for people with a history of breast cancer. It does not increase the risk of breast cancer coming back or of developing a new breast cancer. This is true regardless of the breast cancer type, stage, or hormone receptor status.
Some people experience vaginal dryness or sensitivity during or after breast cancer treatment. Because Phexxi is placed inside the vagina, it may cause irritation or discomfort for some users.
With perfect use, 12 out of 100 people who use Phexxi will get pregnant over a year. Perfect use means that Phexxi is used correctly with each act of sex.
Most people forget to use Phexxi as it should be used. This is called typical use. With typical use, 21 out of 100 Phexxi users will get pregnant over a year.
You can also use another birth control method at the time of sex. We call this a Method Boost because it prevents pregnancy better than Phexxi alone. Method Boost options include the outer condom (penile), inner condom (vaginal), pull out, the cervical cap, and the diaphragm. You can also use these as a Method Backup when you forgot to use Phexxi.
Do not use Phexxi with spermicides or the vaginal ring because Phexxi has not been tested to be used with these methods.
Phexxi makes the vagina more acidic, or acts like an acid. This is safe. You will not feel or smell this change. In fact, the vagina should be acidic because that protects it from bad bacteria. The acidic change makes it harder for sperm to get to the egg.
Phexxi comes in a ready-to-use applicator. You need to put in one full applicator before having penis-in-vagina sex. Using Phexxi is a lot like using a tampon or putting yeast cream in the vagina.
If a little gel is left in the applicator, don’t worry—you’ll still get the right amount if you pushed the plunger all the way. Check the package or Phexxi’s website if you need help.
After putting Phexxi in, it works right away and for up to 1 hour. It stays in place during sex and comes out slowly afterward, mixed with vaginal fluids and semen.
You need to put in a new applicator of Phexxi every time you have sex, even if it’s within the same hour. So, if you plan to have sex again, always use a fresh dose beforehand.
Because Phexxi has no hormones, it does not affect your period.
Phexxi is hormone free. It is safe for people who cannot use hormonal birth control. Phexxi is controlled by you, not your partner.
You have to remember to put it in before sex.
Phexxi is very safe. There are possible annoying side effects, like burning or irritation of the vagina or penis.
Though less common, others have reported getting yeast infections or UTIs (bladder infections).
No. However, correct use of condoms can prevent HIV and STIs.
You can get a prescription from your health care provider.
There are also online birth control services. A licensed health care provider will review your health history.
Phexxi can cost up to $300 a month.
If your insurance covers Phexxi, you may pay $0-$20
