Phexxi

lactic acid / citric acid / potassium bitartrate
Used for Birth Control

Phexxi is a prescription vaginal gel used as a type of birth control to prevent pregnancy. It’s hormone-free, so it doesn’t contain any hormones. Instead, it has three active ingredients: lactic acid, citric acid, and potassium bitartrate. Though it’s not a spermicide, it’s used the same way — by inserting it into the vagina before sex, as needed. Common side effects include vaginal burning, vaginal itching, and yeast infections.

What is Phexxi?

What is Phexxi used for?

How Phexxi works

Phexxi is a vaginal pH regulator. It works by changing the pH of the vagina during sex, making the vaginal environment more acidic during sex. This makes it harder for sperm to move up to where the egg is, which lowers your risk of pregnancy.

Pharmacist tips for Phexxi

pharmacist
  • You can use Phexxi even if you have a vaginal infection. It’s also safe to use with vaginal medications like miconazole (Monistat), metronidazole (Vandazole), and tioconazole (Vagistat-1).
  • Use Phexxi right before or up to 1 hour before vaginal sex. Since this medication is used to prevent pregnancy, stop using it if you become pregnant, as it’s no longer needed.
  • You can use Phexxi at any time, including while you’re on your period. Just make sure you use a new single dose applicator each time you have vaginal sex with your partner.
  • It’s okay to use Phexxi as soon as your OB-GYN provider says it's safe to have vaginal sex after childbirth, abortion, or miscarriage.
  • Phexxi doesn’t protect you against HIV and other sexually transmitted infections (STIs). Talk to your prescriber if you have questions about ways to protect yourself from these infections.
  • If you're allergic to any ingredients in Phexxi (lactic acid, citric acid, or potassium bitartrate), you might also be allergic to the medication itself. Mild side effects like local burning, itching, and pain can occur, and your partner might experience these too. Let your prescriber know if these symptoms become bothersome.

How to use Phexxi:

  • It’s important to read the Instructions For Use before using Phexxi to make sure you use it correctly.
  • Take the applicator and plunger out of the foil wrapper. Insert the plunger into the end of the applicator and slowly push until they connect. Once connected, remove the pink cap.
  • Gently insert the applicator into your vagina. Then, using your index finger, push the plunger down until it stops to make sure all the gel is inserted. Remove the applicator and plunger, and throw them away.

Risks and warnings for Phexxi

Phexxi can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.

Urinary tract infections (UTI)

  • Risk factors: Repeated urinary tract infections (UTI) | Other urinary tract conditions

Phexxi can raise your risk for urinary tract infections (UTI), including bladder infection (cystitis) and a kidney infection (pyelonephritis). Your risk is higher if you have a history of UTIs or other urinary tract conditions. Even though UTIs are common, they can be serious if left untreated. If you experience symptoms like pain or burning during urination, cloudy urine, pain in the pelvis, or back pain, let your prescriber know or speak to another healthcare professional as you might need antibiotics to treat the UTI.
