After Botox administration, which complication requires monitoring for potential respiratory compromise?

• A. Respiratory paralysis
• B. Dysphagia
• C. Hypertension
• D. Nausea

Answer: (B)

Botulinum toxin causes weakness by blocking acetylcholine release at the neuromuscular junction. When the muscles responsible for swallowing are affected, dysphagia can occur, which raises the risk of aspiration and subsequent respiratory problems. Monitoring for dysphagia after Botox is crucial because signs like coughing or choking during swallowing, nasal/hoarse voice, or difficulty clearing secretions can indicate airway protection is impaired, signaling potential respiratory compromise. Keep an eye on changes in breathing or oxygenation as well, and report any swallowing difficulties promptly. Hypertension and nausea aren’t directly tied to airway protection in this context, and true respiratory paralysis is much less common, making dysphagia the most relevant complication to watch for.
