  • Who shouldn’t take Vyleesi?

    Women should not use Vyleesi if they have high blood pressure that is not controlled (uncontrolled hypertension) or known heart (cardiovascular) disease.

    Vyleesi is not for the treatment of HSDD in women who have gone through menopause or in men.

    Vyleesi is not for use to improve sexual performance. Vyleesi is not for use in children.

    Before using Vyleesi, tell your healthcare professional if you are pregnant or plan to become pregnant. It is not known if Vyleesi will harm your unborn baby. Women who can become pregnant should use effective birth control during treatment with Vyleesi.

    Patients should avoid using Vyleesi with an orally administered naltrexone-containing product intended to treat alcohol and opioid addiction due to the severe consequence of naltrexone treatment failure.

  • What is HSDD?

    That’s the abbreviation for hypoactive sexual desire disorder. It’s a common, treatable medical condition characterized by ongoing low sexual desire that women find frustrating (“hypoactive” means “low”).

    If you’re diagnosed with “acquired, generalized” HSDD, it means you haven’t had low sexual desire in the past, but you now have low sexual desire no matter the sexual activity, situation, or sexual partner.

    If you’ve never heard of HSDD, you’re not alone. One survey showed that 72% of premenopausal women weren’t aware of HSDD,* even though about 10% of premenopausal women in the US have it.

  • What’s Vyleesi?

    Vyleesi (bremelanotide injection) is the first and only FDA-approved as-needed treatment for premenopausal women with acquired, generalized hypoactive sexual desire disorder (HSDD). It was approved by the FDA on June 21, 2019.

    Do not use if you have:

    • high blood pressure that is not controlled (uncontrolled hypertension)
    • known heart (cardiovascular) disease

    See clinical trials info.

  • What are the possible side effects of Vyleesi?

    Vyleesi can cause serious side effects, including:
    Temporary increase in blood pressure and decrease in heart rate: an increase in blood pressure and decrease in heart rate can happen shortly after you inject Vyleesi. These changes usually go away within 12 hours after your injection. Increases in blood pressure and an increased risk of heart (cardiovascular) problems can happen if you use Vyleesi more often than prescribed by your healthcare professional.

    See “How should I use Vyleesi?”

    Darkening of the skin on certain parts of the body (focal hyperpigmentation), including the face, gums (gingiva), and breast. The chance of darkening of the skin is increased in people with darker skin color. The chance of darkening of the skin is higher if Vyleesi is used every day. Darkening of the skin may not go away, even after you stop using Vyleesi. Tell your healthcare professional if you have any concerns about changes to your skin.

    Nausea. Nausea is common and can also be severe. Nausea most commonly happens after the first Vyleesi injection but can also happen after any dose of Vyleesi. The nausea usually lasts for about 2 hours but can last longer in some people. The nausea usually goes away by itself. Tell your healthcare professional if you have nausea that is severe or does not go away. Your healthcare professional may prescribe an anti-nausea medicine for you.

    The most common side effects of Vyleesi include:

    • nausea
    • flushing
    • vomiting
    • hot flush
    • nasal congestion
    • injection site reactions
    • cough
    • tingling
    • headache
    • fatigue
    • dizziness

    These are not all the possible side effects of Vyleesi.

    Call your doctor for medical advice about side effects. You may report side effects to the FDA at 1-800-FDA-1088.

    For more information about using Vyleesi, please read the Vyleesi Patient Information.

  • What do you mean Vyleesi can be taken “as needed”?

    It means that if you have a prescription for Vyleesi, you can decide when is the best time to take it, any time of day, based on your own experience, as long as you administer Vyleesi at least 45 minutes before anticipated sexual activity. Do not administer more than one dose within 24 hours or more than 8 doses per month.

    (PS: Vyleesi has no alcohol restriction.)

    Please use Vyleesi exactly as prescribed by your healthcare professional.

    Watch our video, “How to take Vyleesi.”

  • What’s a specialty pharmacy and how does it work?

    A specialty pharmacy handles medications that have special storage, delivery, or administration requirements. When you get a medication through a specialty pharmacy, you don’t go there to pick it up; it’s shipped directly to you. They also work to verify your insurance and help with any co-pay assistance that may be available to you. Vyleesi is handled by special pharmacies only. So if your healthcare professional prescribes Vyleesi for you, this is how you’ll get it:

    Step 1: Your prescription gets submitted
    Your healthcare professional will send your prescription to the specialty pharmacy, KnippeRx®. Specialty pharmacies handle medications that have special storage, delivery, or administration requirements.

    Step 2: You get a call (or text)
    Be on the lookout for a text and/or phone call from KnippeRx®. It may be a couple of days after your appointment. They are contacting you to process your prescription by:

    • Verifying  insurance
    • Helping with co-pay assistance
    • Arranging your delivery of Vyleesi (you may be able to schedule your delivery online)

    Step 3. Vyleesi shows up at your door
    The specialty pharmacy will ship your Vyleesi directly to you, with overnight or two-day shipping. You can track your package, if you like, and it will be delivered quickly and discreetly to your door.

    PS: KnippeRx® has on-call pharmacists that will answer your questions.

  • Does Vyleesi work?

    Here’s what two identically designed clinical trials with over 1,200 premenopausal women with HSDD* showed:

    Vyleesi increased sexual desire and reduced related distress.

    Women who took Vyleesi experienced continued meaningful improvement of HSDD symptoms, with nearly 80% of women who completed the clinical study volunteering for an additional one-year extension.

    The most common side effects are nausea, flushing, injection site reactions, headache, and vomiting.


    *The effectiveness and safety of Vyleesi were studied in two identical trials in over 1,200 premenopausal women with acquired, generalized HSDD for at least six months. Ages ranged from 19-56 years old, with an average age of 39 years old; 86% were White and 12% were Black. The trials had two phases: a 24-week Core Study Phase (24-week placebo-controlled, double-blind treatment period) and an uncontrolled 52-week Open-label Extension Study Phase in which nearly 700 patients received Vyleesi. Most people who received Vyleesi used it two to three times per month and no more than once a week.

    Serious adverse reactions were reported in 1.1% of Vyleesi-treated patients and 0.5% of placebo-treated patients.

  • How common is hypoactive sexual desire disorder (HSDD)?

    HSDD is experienced by an estimated 1 in 10 premenopausal women in the US. It’s the most common medical condition to cause sex-related distress for women, affecting self-esteem and putting a strain on relationships. However, most susceptible women—around 72%*— aren’t aware of it. And those experiencing HSDD often don’t discuss it with their doctors or seek treatment. Now, you can help change the conversation by starting it.
