Safety Profile of Mass Administration of Albendazole Among School Children (6-19 Years): A Prospective Active Surveillance Study.

BACKGROUND: Infections with Soil-transmitted Helminths (STHs) impact about 24% of the global population. A disproportionate number of individuals, particularly those from low socioeconomic backgrounds, live in emerging nations. In India, between the ages of one and fourteen, almost 220 million children are susceptible to intestinal worm infestations caused by parasites. The National Deworming Day (NDD) initiative was started by the Indian government in February 2015 as a part of the National Health Mission to address this problem. Though the adverse effects of albendazole in routine therapy are known, the mass administration of the medicine in children as part of a public health program has not been adequately studied. OBJECTIVE: This study aimed to determine the occurrence, type, and severity of adverse drug reactions resulting from mass administration of albendazole in school children aged 6-19 years in a district of northern India. METHODS: Twenty specified clusters were randomly chosen from a total of 96 clusters in the district to participate in this prospective, descriptive, observational study that was carried out in Karnal, Haryana. Both a passive approach and an active adverse drug reaction reporting system were used in the study. The six-step process known as Deb's Active Surveillance & Assisted Reporting System was employed in our study. Adverse drug reactions were recorded using the suspected Adverse Drug Reaction (ADR) reporting form of the Pharmacovigilance Programme of India (PvPI). RESULTS: Twenty clusters with a combined total of 94 schools and 12,751 students were observed during the study. In this study, there were more female participants (N = 8,060; 63.21%) than male participants (N = 4,691; 36.78%). A total of 29 ADRs were reported. All reported ADRs were mild in nature. It was discovered that there were 1.37 incidences for every 1000 individuals. As illustrated in Fig. (1), the most frequently reported Adverse Drug Reactions (ADRs) were vomiting (N = 10), nausea (N = 4), abdominal pain (N = 2), and headache (N = 1). The majority of ADRs were categorized as probable (N=18; 62.06%), followed by possible (N=11; 37.93%). CONCLUSION: An active surveillance system alongside voluntary passive reporting during the mass administration of medicines can help evaluate the safety profile of the medicinal products. The occurrence of ADRs following mass administration of albendazole in school children was found to be only 1.37 incidences for every 1000 recipients, being mild in nature, with vomiting being the most common.

Delirium following pregabalin discontinuation in an individual with no psychiatric or substance use history.

We report about a man in his mid-50s who was prescribed pregabalin (150 mg/day) for neuropathic pain due to a herniated intervertebral disc. Four weeks later, he presented to the emergency room with symptoms consistent with delirium. After ruling out acute intoxication with a substance and neurological causes, collateral information from the family and review of his medical chart indicated potential discontinuation syndrome owing to pregabalin. Following the successful treatment and resolution of delirium, the patient revealed he had been consistently consuming pregabalin doses upwards of 2 g/day over the past 2 weeks, leading to the premature exhaustion of his prescription and an abrupt cessation. The case findings underscore the necessity for physicians to recognise the potential for pregabalin misuse and the associated withdrawal risks, including delirium.

Abrupt Withdrawal From Chronic High-Dose Zolpidem Use: A Case Report of Resulting Delirium.

We report the case of a male in his twenties who was prescribed 10 mg of zolpidem daily for sleep disturbances. Within one month, he self-augmented the dose to 30 mg daily. Unable to secure an authorized refill, he sought unauthorized suppliers and increased his daily intake to 70 mg over eight months. One day after his medication supply was depleted, he presented to the emergency department with symptoms indicative of acute delirium. Delirium was successfully alleviated within six hours using lorazepam. This was followed by a five-day lorazepam tapering regimen during the patient's hospital stay and then a subsequent four-day taper in an outpatient setting. This case highlights the dangers associated with zolpidem misuse, the swift onset of withdrawal symptoms following abrupt discontinuation, and the crucial importance of rigorous prescription monitoring and patient education regarding the risks of unguided dosage modifications and the sudden cessation of zolpidem.
