At a pharmacological level, it is considered to influence the electrical stability of the heart by modulating the inward sodium current in cardiac membranes. Commonly observed effects include localized digestive changes such as vomiting or a temporary decrease in appetite and behavioral shifts like lethargy or coordination changes (ataxia). Because it influences cardiac rhythm, your veterinarian will monitor for observational signs of heart health through periodic ECGs. Owners should monitor for any unusual weakness or fainting episodes and contact their veterinarian promptly with any concerns.
