Possible side effects of IMCIVREE


Actor portrayals
IMCIVREE was well studied, and most side effects were generally mild and improved over time
The most common side effects of IMCIVREE include:
- Darkening of the skin (hyperpigmentation)
- Injection site reactions
- Nausea
- Headache
- Diarrhea
- Stomach pain
- Vomiting
- Depression
- Erection that happens without
any sexual activity in males
In clinical trials of obesity due to POMC, PCSK1, or LEPR deficiency, reported incidences of nausea and vomiting were nearly all mild, none were severe, and all typically resolved within a few days.
These are not all the possible side effects of IMCIVREE. Call your doctor for medical advice about side effects.
The safety of IMCIVREE has been evaluated in more than 700 people over 10+ years through clinical trials and real-world experience across multiple approved uses.
A general darkening of the skin (hyperpigmentation) is expected because of how IMCIVREE works
Examples of hyperpigmentation
- Darkening of the skin and/or hair is expected, as IMCIVREE may lead to increased production of melanin (which gives color to your skin and hair)
- The degree of skin darkening can vary from person to person and can sometimes include darkening of existing skin growths (such as moles); the degree of darkening may depend on how much natural melanin a person has
- In the clinical trials, hyperpigmentation increased over the first several weeks of IMCIVREE use and generally leveled off in the initial months of treatment
- Darkening of the skin went away after people stopped using IMCIVREE
- If hyperpigmentation is a concern, talk to your doctor and they will assess your response to treatment and work with you to create a plan to check for skin changes
You should have a full-body skin exam before starting and during treatment with IMCIVREE to check for skin changes.
Please review all the possible side effects of IMCIVREE included in the Patient Information and talk to your doctor about any questions you may have.
