At a pharmacological level, it is considered to influence smooth muscle contraction by noncompetitively blocking alpha-1 receptors. Commonly observed effects include behavioral shifts such as temporary lethargy or cardiovascular changes like low blood pressure (hypotension). Because it influences vascular tone, your veterinarian will monitor for observational signs of weakness or increased heart rate. Owners should monitor for significant changes in activity or fainting episodes and contact their veterinarian promptly with any concerns.

Low blood pressure is a commonly observed effect, which may manifest as weakness. Your veterinarian will provide guidance on what level of lethargy is expected and how to monitor your pet's energy during the course of management.
