But in practice, and especially with regard to synthetic and recombinant peptide forms, there are some considerable potential safety concerns: Immunogenicity Most notably, per a 2020 assessment on therapeutic peptide safety, synthetic and recombinant peptides pose the risk of immunogenicity the ability of a substance to provoke an immune response.15 An immunogenicity-inducing peptide, when introduced to the body, would cause the bodys immune system to perceive the peptide not as a medication but as a threat
This dual mechanism is what makes tirzepatide more effective than semaglutide for weight loss, but it also creates specific pharmacodynamic considerations that make dosing frequency modifications riskier
The World Health Organization (WHO) has issued a formal safety alert confirming that semaglutide medications, including Ozempic , Wegovy , and Rybelsus are associated with a very rare but serious risk of permanent vision loss caused by non-arteritic anterior ischemic optic neuropathy (NAION)
