How bremelanotide is dosed

From the FDA label for Vyleesi (Autoinjector) (application NDA210557). Other bremelanotide products — different forms, different strengths — are dosed differently. Follow the label for the one you were prescribed.

Inject 1.75 mg subcutaneously via the autoinjector to the abdomen or thigh, as needed, at least 45 minutes before anticipated sexual activity. ( 2.1 ) Do not administer more than one dose within 24 hours. ( 2.1 ) More than 8 doses per month is not recommended. ( 2.1 ) 2.1 Recommended Dosage The recommended dosage of VYLEESI is 1.75 mg administered subcutaneously in the abdomen or thigh, as needed, at least 45 minutes before anticipated sexual activity. The duration of efficacy after each dose is unknown and the optimal window for VYLEESI administration has not been fully characterized. Patients may decide the optimal time for VYLEESI administration based on how they experience the duration of effect on desire and any adverse reactions such as nausea [see Warnings and Precautions ( 5.3 )]. Patients should not administer more than one dose within 24 hours. The efficacy of consecutive doses within 24 hours has not been established and administering doses close together may increase the risk of additive effects on blood pressure [see Warnings and Precautions ( 5.1 )]. Administering more than 8 doses per month is not recommended. Few patients in the phase 3 program received more than 8 doses per month. Also, more frequent dosing increases the risk for focal hyperpigmentation and the length of time per month when blood pressure is increased [see Warnings and Precautions ( 5.1 , 5.2…

Bremelanotide side effects

The following adverse reactions are discussed in greater detail elsewhere in labeling: Transient increases in blood pressure and reductions in heart rate [see Warnings and Precautions ( 5.1 ) and Clinical Pharmacology ( 12.2 ) ] Focal hyperpigmentation [see Warnings and Precautions ( 5.2 )] Nausea [see Warnings and Precautions ( 5.3 ) ] Most common adverse reactions (incidence > 4%) are nausea, flushing, injection site reactions, headache, and vomiting. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Cosette Pharmaceuticals, Inc. at 1-800-922-1038 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to the rates in the clinical trials of another drug and may not reflect the rates observed in practice. The efficacy and safety of VYLEESI was studied in two identical, 24-week, randomized, double-blind, placebo-controlled trials in 1247 premenopausal women with acquired, generalized HSDD. The age range was 19-56 years old with a mean age of 39 years old; 86% were White and 12% were Black. Both trials also included a 52-week open-label, uncontrolled extension phase during which 684 patients received VYLEESI [see Clinical Studies ( 14 )]. Most patients used VYLEESI two to three times per…

Who shouldn’t take bremelanotide

VYLEESI is contraindicated in patients who have uncontrolled hypertension or known cardiovascular disease [see Warnings and Precautions ( 5.1 )]. Uncontrolled hypertension or known cardiovascular disease. ( 4 )

Bremelanotide drug interactions

VYLEESI may slow gastric emptying and impact absorption of concomitantly administered oral medications. ( 7.1 ) VYLEESI may significantly decrease the systemic exposure of orally-administered naltrexone; avoid use with orally administered naltrexone-containing products intended to treat alcohol or opioid addiction. ( 7.2 ) 7.1 Effect of VYLEESI on Other Drugs VYLEESI may slow gastric emptying and thus has the potential to reduce the rate and extent of absorption of concomitantly administered oral medications. Instruct patients to avoid the use of VYLEESI when taking concomitant oral drugs that are dependent on threshold concentrations for efficacy (e.g., antibiotics). In addition, patients should consider discontinuing VYLEESI if there is a delayed drug effect of concomitant oral medications when a quick onset of drug effect is desired (e.g. drugs for pain relief such as indomethacin). 7.2 Naltrexone As VYLEESI may significantly decrease the systemic exposure of orally-administered naltrexone, patients should avoid using VYLEESI with an orally administered naltrexone-containing product that is intended to treat alcohol and opioid addiction due to the severe consequence of naltrexone treatment failure [see Clinical Pharmacology ( 12.3 )].

Bremelanotide and breastfeeding

From LactMed, the US National Library of Medicine’s Drugs and Lactation Database — quoted, not rewritten.

No information is available on the clinical use of bremelanotide during breastfeeding. Because bremelanotide is a cyclic peptide molecule with a molecular weight of 1025, the amount in milk is likely to be very low and absorption is unlikely because it is probably destroyed in the infant's gastrointestinal tract. Until more data become available, bremelanotide should be used with caution during breastfeeding, especially while nursing a newborn or preterm infant.

Frequently asked questions

What is bremelanotide?

VYLEESI (bremelanotide injection) contains bremelanotide, a melanocortin receptor agonist for subcutaneous administration via an autoinjector.

What kind of drug is bremelanotide?

The FDA classifies bremelanotide as a melanocortin receptor agonist. If you are checking whether it is safe to combine with something else, the class is what matters — two drugs from the same class usually should not be stacked.

Can you take bremelanotide with other medicines?

It depends on the medicine. We check it against the FDA labels rather than guessing: our interaction checker searches each drug's own label for the other and quotes what it says, naming the section it came from. Run bremelanotide against whatever else you take — and remember that a label not naming a drug is not the same as that combination being safe.

What forms does bremelanotide come in?

Across the brands we track, bremelanotide is currently marketed as injectable, per the FDA's National Drug Code Directory. Each form is dosed differently — follow the label for the exact product you were prescribed.

Is there a generic bremelanotide?

We do not currently list a generic-labelled bremelanotide product. That does not always mean none exists — it means none appears under a generic name in the FDA data we track. Ask your pharmacist.
