What the older studies reported
In the older research, brief facial flushing and pain at the injection spot were the most often reported unwanted effects.
Most of that evidence came from children and does not give a rate for adults using pharmacy-made sermorelin today.
Some children’s bodies reacted to the medicine by making antibodies, substances that attach to things the body treats as foreign. Their growth did not seem to be affected.
Those findings in children do not tell us how adults’ bodies react to pharmacy-made sermorelin today.
What today’s information cannot settle
As of September 2026, sermorelin has no current FDA label giving reviewed rates of side effects or information about pregnancy.
Raise pregnancy, plans for pregnancy and breastfeeding during the discussion. Ask what evidence applies, what remains uncertain and what alternatives the clinician would consider.
Also ask how the service handles a new symptom after treatment begins and who can answer questions about the preparation.
When symptoms need urgent help
A severe allergic reaction can develop very quickly and is a medical emergency, according to MedlinePlus.
For severe symptoms such as trouble breathing or swelling of the face or tongue, MedlinePlus advises calling 911 or seeking emergency-room care.
This is a trigger to seek urgent help, not a test to identify the cause yourself.
Read the effects and emergency sourcesThe point to carry forward.
Ask what unwanted effects have been reported and what is still unknown about the exact medicine being offered.

Keep the limits attached to the findings
The older studies mainly describe children, and the FDA warnings discussed here concern other medicines. Sermorelin has no current FDA drug information sheet, so there are gaps in the safety information for adults today.
Ask which findings apply to the proposed plan and what remains uncertain.
