Potential general causes of discolouration in biological medicines include: Temperature excursions : Exposure to temperatures outside the recommended storage range (particularly heat) can cause protein degradation and chemical changes that may alter the solution's appearance [9] [10] Contamination : Though rare in unopened sterile products, introduction of foreign substances or particulate matter could potentially cause colour changes Chemical degradation : Oxidation or other chemical reactions affecting the peptide structure may result in discolouration Manufacturing defects : Though rare, quality control issues during production could theoretically result in off-specification products Interaction with packaging materials : In exceptional circumstances, degradation of pen components or seals might introduce coloured substances into the solution It is important to note that biological medications like tirzepatide are particularly sensitive to environmental conditions

At the core of Ozempic's formulation is the active ingredient semaglutide, a glucagon-like peptide-1 (GLP-1) receptor agonist that mimics the action of the natural hormone GLP-1
