Ranitidine overdose

Overdose Information
Human Experience Overdose Management

Human Experience
There is very limited experience with Ranitidine overdose. In premarketing clinical studies, there were eight reports of Ranitidine overdose alone or in combination with other pharmacological agents. The only drug overdose death reported while taking Ranitidine was in combination with amitriptyline and chlorprothixene in a non-US clinical study. Based on plasma levels, the Ranitidine dose taken was 30–45 mg, while plasma levels of amitriptyline and chlorprothixene were found to be at toxic levels. All other premarketing overdose cases resulted in full recovery. Signs and symptoms reported in association with overdose included disorientation, drowsiness, impaired memory, and tachycardia. There were no reports of ECG abnormalities, coma or convulsions following overdose with Ranitidine alone. Return to top

Overdose Management
Treatment should consist of those general measures employed in the management of overdose with any drug effective in the treatment of major depressive disorder. Ensure an adequate airway, oxygenation, and ventilation. Monitor cardiac rhythm and vital signs. General supportive and symptomatic measures are also recommended. Induction of emesis is not recommended. Gastric lavage with a large-bore orogastric tube with appropriate airway protection, if needed, may be indicated if performed soon after ingestion, or in symptomatic patients. Activated charcoal should be administered. There is no experience with the use of forced diuresis, dialysis, hemoperfusion or exchange transfusion in the treatment of mirtazapine overdosage. No specific antidotes for mirtazapine are known. Return to top
