Sermorelin Beyond the pituitary signal

Understand sermorelin and find care with these briefings

The unwanted-effects briefing

Why it left the market is only part of the picture.

A finding about the old medicine cannot answer every question about care offered now.

The short answer

The U.S. agency for medicine reviews has the full name Food and Drug Administration; these briefings use its initials, FDA.

In March 2013, the FDA found that sermorelin (Geref) did not leave the market because of safety or a failure to work.

As of September 2026, that finding does not give today's pharmacy-made medicine FDA approval or show it is safe for adult treatment.

What was reported, and what is still unknown

  • What the older studies reported

    Brief facial redness and pain where the injection went in were the effects most often reported in older studies.

    Those reports came largely from children and do not tell us how often unwanted effects happen in adults today.

  • What is still unknown for adults

    As of September 2026, there are no current FDA-reviewed instructions and warnings for prescribing sermorelin.

    There is no current FDA-reviewed information on how often unwanted effects happen in adults or what to expect during pregnancy.

    The body uses growth hormone as one of its chemical messages.

    The FDA's reviews of related drugs discuss possible concerns from raised growth hormone, including high blood sugar, fluid build-up, and tumours.

    That is a concern about related drugs, not proof that sermorelin causes these harms.

  • Ask how the pharmacy checks the medicine it makes

    Compounding means making a medicine to order.

    The mix may be dirty or have the wrong strength when compounding is poor.

    Ask who makes it and what checks are done before it reaches you.

When help cannot wait

Signs of a severe allergic reaction may include the face or tongue swelling, difficulty with breathing or swallowing, or passing out.

MedlinePlus directs people with these severe symptoms to call 911 or get to whichever emergency room is nearest.
