The most common side effects of Sermorelin include injection site reactions (pain, swelling, redness), headache, flushing, dizziness, and nausea. These are usually mild and transient.
Serious side effects are rare but may include severe allergic reactions, changes in blood pressure, or increased intracranial pressure. Seek immediate medical attention if these occur.
These are not all the possible side effects of Sermorelin. Talk to your healthcare provider about any side effect that bothers you or doesn't go away.
