Imcivree (setmelanotide)

What is Imcivree (setmelanotide), and how is it used?

  • Imcivree (setmelanotide) is a prescription medicine used in adults and children 6 years of age and older with obesity due to the genetic conditions proopiomelanocortin (POMC), proprotein convertase subtilisin/kexin type 1 (PCSK1), or leptin receptor (LEPR) deficiency, to help them lose weight and keep the weight off.
  • Your healthcare provider should order a genetic test to confirm POMC, PCSK1, or LEPR deficiency before you start using Imcivree.
  • Imcivree is not for use in people with the following conditions because it may not work:
    • Obesity due to suspected POMC, PCSK1, or LEPR deficiency not confirmed by genetic testing (benign or likely benign result).
    • Other types of obesity not related to POMC, PCSK1, or LEPR deficiency, including obesity associated with other genetic conditions and general obesity.

What are the side effects of Imcivree?

Imcivree may cause serious side effects, including:

  • Male and female sexual function problems. Imcivree can cause an erection that happens without any sexual activity in males (spontaneous penile erection) and unwanted sexual reactions (changes in sexual arousal that happen without any sexual activity) in females. If you have an erection lasting longer than 4 hours, get emergency medical help right away.
  • Depression and suicidal thoughts or actions. You or a caregiver should call your healthcare provider right away if you have any new or worsening symptoms of depression.
  • Increased skin pigmentation and darkening of skin lesions (moles or nevi) you already have. These changes happen because of how Imcivree works in the body and will go away when you stop using Imcivree. You should have a full body skin exam before starting and during treatment with Imcivree to check for skin changes.
  • Benzyl alcohol toxicity. Benzyl alcohol is a preservative in Imcivree. Benzyl alcohol can cause serious side effects, including death, in premature and low-birth weight infants, who have received medicines that contain benzyl alcohol. Imcivree should not be used in premature and low-birth weight infants.
