Common Symptoms of Albuterol Overdose
Albuterol overdose most often leads to a group of symptoms that include agitation, tremors, sinus tachycardia (fast heart rate), hypokalemia (low potassium), and hyperglycemia (high blood sugar) 234567. Vomiting and restlessness are also frequently observed, especially in children 246. These symptoms can appear within hours of ingestion and may require close monitoring in a medical setting 246.
Electrolyte and Blood Sugar Abnormalities in Albuterol Toxicity
Hypokalemia (Low Potassium)
Hypokalemia is a well-documented effect of albuterol overdose. It occurs because albuterol stimulates the movement of potassium from the blood into cells, leading to significantly low blood potassium levels 23567. This can cause muscle weakness, tremors, and, in severe cases, dangerous heart rhythm disturbances 23567. In both children and dogs, hypokalemia is a common and important finding that requires monitoring and sometimes potassium replacement 23567.
Hyperglycemia (High Blood Sugar)
Albuterol overdose can also cause high blood sugar (hyperglycemia), which is often seen alongside hypokalemia 3467. This is due to the drug’s effect on the body’s metabolism, increasing glucose release into the blood 3467. Hyperglycemia is usually temporary but should be monitored, especially in children 3467.
Hypoglycemia (Low Blood Sugar)
Although less common, hypoglycemia (low blood sugar) can occur as a late complication after an initial period of high blood sugar 14. This is thought to happen because the body releases extra insulin in response to the earlier high blood sugar, which can then cause blood sugar to drop too low several hours after the overdose 14. Monitoring blood sugar for an extended period is recommended in cases of significant overdose, especially in children 14.
Cardiovascular and Neurological Effects
Sinus tachycardia (fast heart rate) is a frequent symptom of albuterol overdose and can be accompanied by low blood pressure (hypotension) 4567. Patients may also experience tremors, agitation, and restlessness 3456. In rare cases, more serious heart rhythm problems can develop, especially if hypokalemia is severe 57.
Management and Prognosis
Most cases of albuterol overdose, even with significant symptoms, have a good outcome with supportive care such as intravenous fluids, potassium replacement, and close monitoring of heart rhythm and blood sugar 234567. Beta-blockers like propranolol have been used successfully in some cases to control symptoms . In both children and animals, recovery is usually complete within 24 hours if treated appropriately 234567.
Conclusion
Albuterol overdose can cause a range of symptoms, most commonly including agitation, tremors, fast heart rate, hypokalemia, and hyperglycemia. Hypoglycemia may occur later, especially in children. With prompt recognition and supportive care, the prognosis is generally very good. Monitoring of potassium and blood sugar is essential in all suspected cases.
