• Intravenous Fluids: Administering IV fluids may be necessary to maintain hydration and support renal function.

3. Specific Antidotes and Treatments

Depending on the specific non-opioid analgesic involved, different treatments may be indicated:

• Acetaminophen Overdose: The primary treatment is the administration of N-acetylcysteine (NAC), which acts as an antidote by replenishing glutathione levels and preventing liver damage. NAC is most effective when given within 8 to 10 hours of ingestion.
• NSAID Toxicity: There is no specific antidote for NSAID overdose. Treatment focuses on supportive care, including gastric decontamination (activated charcoal) if the patient presents within a few hours of ingestion. In severe cases, renal function may need to be monitored closely, and dialysis may be considered if there is significant renal impairment.

4. Gastrointestinal Decontamination

In cases of recent ingestion, gastrointestinal decontamination may be appropriate:

• Activated Charcoal: Administering activated charcoal can help absorb the drug and reduce systemic absorption, particularly if the patient presents within one hour of ingestion.
• Gastric Lavage: This may be considered in severe cases, although it is less commonly used due to the risk of complications.

5. Psychiatric Evaluation

For cases involving intentional overdose or self-harm, a psychiatric evaluation is crucial. This assessment can help identify underlying mental health issues and guide further treatment, including counseling or psychiatric intervention.

Conclusion
