Zydol Overdosage

Acute Overdose Symptoms: An overdose of Butorphanol Tartrate Injection can cause symptoms such as slow or difficult breathing, drowsiness progressing to stupor or coma, muscle weakness, cold skin, small pupils, and in severe cases, pulmonary edema (fluid in the lungs), slow heart rate, low blood pressure, blocked airways, unusual snoring, and possibly death. Overdose may also cause enlarged pupils due to lack of oxygen.
Overdose Treatment: Symptoms: Symptoms of butorphanol overdose are consistent with those observed with opioid overdose in general. The most serious manifestations include hypoventilation, cardiovascular insufficiency, coma, and death.
Management: In cases of suspected butorphanol overdose, primary attention should be directed toward the establishment and maintenance of adequate ventilation, peripheral perfusion, airway protection, and normal body temperature. Patients should be placed under continuous observation, with serial assessment of mental status, responsiveness, and vital signs.
Oxygen and ventilatory support should be readily available, and pulse oximetry or other appropriate monitoring should be used as indicated. In patients presenting with coma or compromised airway reflexes, endotracheal intubation or placement of another artificial airway may be required. An adequate intravenous access should be secured to facilitate treatment, including the management of hypotension associated with vasodilation.
Opioid Antagonists: The use of an opioid antagonist such as naloxone should be considered. Because the duration of action of butorphanol may exceed that of naloxone, repeated doses or a continuous infusion of naloxone may be necessary to maintain adequate reversal.
