The regulatory history of Geref (sermorelin) does not make current compounded adult preparations approved products.

It is prescribed as a compounded medication by a licensed US provider after an individual evaluation, and it is not an FDA-approved finished drug product. You can read the full overview on the [sermorelin treatment page](/sermorelin/). ## Commonly reported side effects The effects patients and clinicians most commonly report are: - **Injection-site reactions** — temporary redness, swelling, or irritation where the injection is given - **Flushing** — a brief warm or red sensation - **Headache** These are generally mild and local. As with any prescription medication, other effects are possible, and individual experiences differ. ## Why a list is not enough A bulleted list cannot tell you *your* risk. The likelihood and significance of any side effect depend on your health history, current medications, age, and other factors a provider weighs during evaluation. That is the core reason sermorelin is: - **Prescription-only** — a licensed provider decides whether it is appropriate - **Individually screened** — providers check for contraindications and may decline to prescribe - **Monitored** — you have a care team to contact and a provider who can adjust or stop treatment ## What to watch for and what to do Pay attention to anything that feels persistent, worsening, or unusual, and contact your care team if it does. A serious program makes that easy — you are not on your own with a vial. For any severe or urgent symptom, seek emergency care immediately. ## The regulatory context matters Because compounded sermorelin is **not an FDA-approved finished drug product** and has not been studied as a finished product, its risk information comes from clinical understanding of the molecule and from provider oversight — another reason the conversation belongs with a licensed clinician. > **Have questions about whether sermorelin is right for you?** [Start a clinical evaluation with REMEVi](/sermorelin/) — a licensed US provider reviews your history, explains the risks, and decides whether to prescribe.

Sermorelin is a non-FDA-approved compounded medication available only by prescription from a licensed provider after an individual evaluation.* ## Frequently asked questions ### What are the most commonly reported sermorelin side effects? The most commonly reported effects are reactions at the injection site (redness, swelling, or irritation), flushing, and headache. As with any prescription medication, other effects are possible. Your licensed provider will review the full risk profile and your individual risk factors with you before prescribing and will monitor you during treatment. ### Are sermorelin side effects serious? Most commonly reported effects are mild and local, but seriousness depends on the individual, and no medication is risk-free. Because sermorelin is a compounded prescription medication that is not FDA-approved as a finished product, the right way to understand its risks for you is a clinical evaluation, not an online list. ### Who should not take sermorelin? A licensed provider screens for contraindications during evaluation and may decline to prescribe if the clinical picture does not support it. That screening is exactly why sermorelin is prescription-only and is evaluated case by case rather than sold over the counter. ### What should I do if I have a side effect? Contact your care team. In a physician-led program, you have a provider and care coordinator to reach out to if you notice anything concerning, and your provider can adjust the plan or stop treatment if appropriate. For any urgent or severe symptom, seek emergency care. ### Does the injection itself cause side effects? Injection-site reactions — temporary redness, swelling, or irritation — are among the most commonly reported effects and are usually local and mild. Proper technique, which your provider's instructions cover, helps minimize them.
