What do we know about unwanted effects?

In the older sermorelin research, brief facial flushing and soreness at the injection site were the most commonly reported unwanted effects.

Most of that evidence came from studies in children during the 1990s. There are no up-to-date figures for how often these effects happen in adults using pharmacy-made medicine.

Those reports cannot establish that a medicine offered now will be trouble-free.

Throughout this page, FDA means Food and Drug Administration; the initials keep that agency’s name short.

As of September 28, 2026, no sermorelin medicine had current instructions and warnings checked by the FDA.

There is no up-to-date FDA-reviewed list of who must avoid it, how often side effects occur, or what it means during pregnancy.

Growth hormone is a body chemical that helps children grow.

In reviews of related medicines, the FDA raised concerns about high growth hormone levels, including blood sugar changes, fluid build-up, and tumor risks.

The FDA raised these concerns about related drugs. It did not find that sermorelin causes cancer.

Bring pregnancy plans, current health conditions, and all medicines into the personal discussion rather than filling those gaps with an assumption.
