Rational use of paracetamol among out-patients in a Bhutanese district hospital bordering India: a cross-sectional study

Prevalence and Determinants of Self-Medication Practices among Cardiovascular Patients from Béja, North West Tunisia: A Community-Pharmacy-Based Survey

In Tunisia, self-medication is a common practice, and there is a continual rise in the prevalence of cardiovascular disease. Given the lack of data on the self-medication practices (SMPs) among cardiovascular patients in this area, the present study aimed to identify the prevalence and determinants of SMPs among cardiovascular patients in the city of Béja. A community-pharmacy-based survey was conducted among selected cardiovascular patients in Béja, Tunisia, from May 2021 to June 2021. Data were collected using a self-administered questionnaire provided by pharmacists during in-person surveys with patients. Descriptive statistics were used to summarize the data, while Fisher's exact test was used for categorical variables, with the significance level set at p < 0.05. The frequency of self-medication among the 150 respondents was 96%; 70.14% of participants reported that the primary reason why people engage in self-medication is the existence of an old prescription. The most prevalent conditions leading patients to self-medicate were headaches (100%), fever (83.33%), toothache (65.97%), and dry cough (47.92%). The most frequently self-administered drugs were paracetamol (100%), antibiotics (56.94%), and antitussives (47.92%). The results of our study indicate that SMPs among Tunisian cardiovascular patients have a high prevalence. With this in mind, healthcare practitioners should ask their patients about their self-medication practices and advise cardiovascular patients about the risks and benefits associated with this practice.

Sensitivity of dose-estimations for acute acetaminophen overdose in predicting hepatotoxicity risk using the Rumack-Matthew Nomogram

Timely assessment of acetaminophen concentration in overdose situations is not always available in resource-poor settings. The 150 mg/kg dose-estimate for acetaminophen is widely considered as criterion for acetaminophen overdose. Its sensitivity and specificity when compared to the 150 mg/L treatment line on the Rumack-Matthew Nomogram (150-treatment line) has rarely been evaluated. This is a retrospective chart review of acute acetaminophen overdose patients. We evaluated the sensitivity and specificity of the 150, 200 mg/kg and 8- and 10-g dose-estimates by plotting the serum acetaminophen levels and using 150-treatment line on the Nomogram as the treatment cut-off. A comparison of medical care costs was performed. We enrolled 784 cases for analysis. Median (IQR) age was 23 (20-28) years (81.9% female). There were 545 cases (69.5%) where the estimated ingested acetaminophen dose were ≥150 mg/kg and 406 cases (51.8%) with concentrations ≥150-treatment line. Hepatotoxicity and acute liver injury (ALI) occurred in 7.3% and 23.9%, respectively. The sensitivity and specificity of 150 mg/kg dose-estimate for the 150-treatment line were 92.6% (95% CI 89.6, 94.8) and 55.3% (95% CI 50.3, 60.2). Among patients with dose-estimate below150 mg/kg, none developed hepatotoxicity and 17 (7.1%) develop ALI. The administration of activated charcoal significantly decreased the risk of being above the 150-treatment line by half. In resource-poor setings, the use of 150 mg/kg dose-estimate as a stand-alone criteria for initiation of N-acetylcysteine therapy is satisfactory, especially when combined with decontamination with activated charcoal and follow up of aminotransferase at 24 h.

Egyptian perspectives on potential risk of paracetamol/acetaminophen-induced toxicities: Lessons learnt during COVID-19 pandemic

Paracetamol/Acetaminophen was widely used as a first-line antipyretic and analgesic for COVID-19 patients without giving any attention to the potential risk of related toxicities. A survey was conducted on 176 Egyptians using an online survey portal to assess their knowledge, and attitude regarding potential risk of paracetamol toxicities and whether COVID-19 pandemic affected their practices regarding safe use of paracetamol. The self-administered questionnaire was developed by the researchers and was validated by expert opinions. A pilot testing of the questionnaire was done. Alpha Cronbach test used to assess the internal consistency reliability of the survey revealed good reliability. Overall percent-score revealed that only 24.4% of participants had good knowledge about paracetamol and its related potential toxicities. 62.5% of participants considered paracetamol safer than other medications of the same indications. 42.6% of participants could advise others to use paracetamol without prescription. According to the participants' responses, physicians were less concerned to give instructions about possibility of overdosage. Our results also revealed that participants’ administration of paracetamol without physician prescription was more during COVID-19. Practice of paracetamol administration more than the allowed number of tablets/day was significantly more evident during the pandemic. We concluded that the unsupervised use of paracetamol is an alarming sign that should be addressed as this could lead to a high rate of accidental paracetamol toxicity. A lesson learnt from COVID-19 pandemic is the need to implement behavior change measures to mitigate the risk of accidental paracetamol toxicity.

An assessment of parents' knowledge and awareness regarding paracetamol use in children: a cross-sectional study from Palestine

BACKGROUND

Paracetamol, also known as acetaminophen, is one of the most common antipyretic and analgesic over-the-counter (OTC) medicines administered to children due to its efficacy, safety, and availability in many pharmaceutical forms, including suppositories, syrup, and drops. Parents frequently administer the wrong dose of paracetamol by mistake for their children, as reported by many previous studies. We aimed in this study to assess parents' knowledge, attitudes, and practice regarding paracetamol dosing and toxicity, as well as their awareness regarding paracetamol-containing products.

METHODS

This was a cross-sectional study that targeted parents of children seeking healthcare services at primary health care centers in the Nablus area in the West Bank, Palestine. We used questionnaire-based interviews with parents for data collection.

RESULTS

A total of 300 parents were included in the study. Most of the caregivers surveyed were (87%) females (mothers). About half the parents (50.9%) reported previously using paracetamol as an antipyretic in children under the age of six. A quarter (25.4%) preferred the syrup forms, while 33.8% preferred the suppository dosage form. Medical personnel was the primary source of information for half the caregivers (51.2%). The mean knowledge score about paracetamol was 2.1 (SD = 1.4) out of 6, and the median was 2.0 with an interquartile range of 1.0-3.0. Two hundred seventy-four (95.5%) of the participants scored less than 80% and were considered to have insufficient knowledge. Only 50.9% of parents recognized that paracetamol overdose could result in serious harm.

CONCLUSIONS

We found a serious lack of knowledge regarding paracetamol dosing, administration, and potential toxicity among Palestinian parents. We recommend raising awareness regarding this problem among healthcare providers and authorities and working on plans that aim to provide caregivers with accurate and adequate information on dosing, formulation, side effects, and other aspects of paracetamol use, as well as developing effective educational plans targeting healthcare providers, as well as the public.
