TESAMORELIN SAFETY
Tesamorelin Side Effects: What to Know & Monitor
Metabolic, fluid, and cancer-related precautions from the label
⚠ Because tesamorelin affects growth hormone and IGF-1, it is contraindicated in active cancer and pregnancy and requires medical monitoring.
Tesamorelin side effects are well documented in the FDA-approved prescribing information, because tesamorelin affects growth hormone and IGF-1 signaling. For how it works, see the tesamorelin mechanism page.
Metabolic Effects
Tesamorelin raises IGF-1, and the effects of prolonged elevation are not fully known — the label recommends monitoring IGF-1 during treatment. It may also cause glucose intolerance or diabetes, so blood sugar should be evaluated before and during medically supervised use.
