Used for Hirsutism

Florexa (eflornithine) is a prescription cream used to reduce unwanted facial hair in women. It belongs to a group of medications called ornithine decarboxylase inhibitors. The cream is applied to the face and nearby areas under the chin twice a day, at least 8 hours apart. It doesn’t remove hair right away, so you’ll usually keep using your regular hair removal routine while it starts working. Common side effects include acne, stinging skin, and burning skin.

Pharmacist tips for Florexa (eflornithine)

pharmacist
  • Use Florexa (eflornithine) twice a day, at least 8 hours apart. This helps keep the medication working steadily. Using it regularly can help you get the most benefit from treatment.
  • Keep using your usual hair removal methods while taking Florexa (eflornithine). It slows new hair growth but doesn't remove hair that's already there, so you might still need to shave, pluck, or use other methods.
  • Give Florexa (eflornithine) time to work. You might notice improvement after 4 to 8 weeks, but if you don't see any improvement after 6 months, tell your prescriber.
  • Don’t apply Florexa (eflornithine) to broken or irritated skin. Doing so can cause more stinging, burning, or irritation.
  • Pregnancy: Talk to your prescriber before using Florexa (eflornithine) if you’re pregnant. There isn't enough information to know whether it's safe during pregnancy.
  • Breastfeeding: Talk to your prescriber before using Florexa (eflornithine) if you're breastfeeding. It's not known whether the medication passes into breast milk.
  • Storage: Keep Florexa (eflornithine) below 86°F (30°C). Protect the cream from high temperatures.

How to use Florexa (eflornithine)

  • Apply the cream to clean, dry skin. Spread a thin layer over the affected areas of your face and under your chin, then rub it in well.
  • Don’t wash the treated skin for at least 4 hours after applying the cream. This gives it time to absorb.
  • Wait at least 5 minutes after removing facial hair before applying the cream. This can help reduce stinging or burning after shaving, plucking, or waxing.
  • Let the cream absorb before using other skin products. Wait a few minutes before applying cosmetics or sunscreen so you don’t wipe it away too soon.
