If you overdose on melatonin, common symptoms include excessive sleepiness, dizziness, stomach upset, fatigue, confusion, headache, irritability, nausea, and increased heart rate. More serious symptoms that require immediate medical attention can be difficulty breathing, chest pain, seizures, tremors, and a rise in blood pressure. Melatonin overdose is generally not life-threatening but can cause discomfort and complications depending on individual factors such as age and underlying health conditions. If an overdose occurs, stopping melatonin use and seeking medical advice is important, especially if severe symptoms appear. Emergency care should be sought if there is loss of consciousness, irregular breathing, or other critical symptoms. Melatonin toxicity is low, and fatalities are extremely rare even with high doses, but monitoring and supportive care are essential in overdose cases.
