Introduction: Aluminum phosphide (ALP), locally known as "Rice Tablet", is a cheap and powerful pesticide used frequently to protect cereals. Cases of ALP toxicity have grown dramatically in recent decades by using it for suicide purposes. Treatment of ALP toxicity is largely supported by various remedies as there is no specific antidote. This study deals with the epidemiology of ALP toxicity in Khuzestan (Iran) and assesses the clinical and paraclinical manifestations, as well as the results of various treatments during the last 12 years. The study further examines the next suicidal intentions and subsequent complications of poisoning with ALP.

Methodology: The records of all patients with ALP toxicity admitted to Razi Hospital in Ahvaz from 2006 to 2017 were reviewed within a retrospective study. Epidemiological and demographic information, clinical and paraclinical manifestations, and the results of various treatments were extracted. Data on the subsequent complications and the next suicidal intentions in those who have survived a suicide attempt were gathered and analyzed.

Results: Of the 48 patients studied, 50% were male and the mean age was 29.33±10.45. Most of the toxicities were orally and with the intention of suicide in Ahvaz and Andimeshk. A total of 71.42% of the dead have been carried to this center. The majority of cases were reported from urban areas and in August and during summer. The most prevalent clinical signs were loss of consciousness, nausea, and vomiting. There were some differences in the experimental and EKG results. A meaningful correlation was observed between the administration and/or consumption of ranitidine, NAC, and intravenous sodium bicarbonate with treatment outcomes. Only one case of reattempt to suicide has been reported, and hematuria, ascites, and pleural effusion were widely visible in survivors.

Conclusion: On-call counseling may decrease the rate of mortality in dispatching patients. Clinical and paraclinical manifestations can be useful in the diagnosis or prognosis. Patients' follow-up, actions to enhance public awareness, restrictions on the distribution of ALP, and availability of alternative substances can be helpful to diminish cases of ALP toxicity and/or death.
