Background/Objectives: Difficult-to-treat epileptic syndromes include conditions typically emerging in the first years of life and are characterized by a high rate of drug refractoriness. This study aimed to better define the safety profile of drugs used as adjunctive therapies for seizures associated with these syndromes using real-world pharmacovigilance data. Methods: We retrospectively analyzed the publicly available data regarding Individual Case Safety Reports (ICSRs), presenting stiripentol, cannabidiol, or fenfluramine as suspected drugs, reported on the Eudravigilance database until the third quarter of 2024. Data were evaluated with descriptive analyses and then with disproportionality measures, including the reporting odds ratio. Results: A total of 5986 ICSRs met the inclusion criteria (71.6% from cannabidiol, 14.5% fenfluramine, and 13.9% stiripentol). Significantly higher probabilities of reporting Cardiac disorders, Vascular disorders, and Respiratory, thoracic, and mediastinal disorders were observed with fenfluramine. Cannabidiol was associated with Product issues, whereas stiripentol was associated with injury, poisoning, procedural complications, Metabolism and nutrition disorders, and Blood and lymphatic system disorders. Conclusions: Our analysis did not highlight new and unexpected serious safety signals but confirmed the need to strictly monitor patients for the risk of adverse events. However, further prospective studies are required to better clarify the safety profile of these drugs in order to optimize their use. Full article

Background: Medication safety in pregnancy, puerperium, and perinatal periods is underexplored because these populations are excluded from clinical trials. EudraVigilance offers post-marketing evidence, but disproportionality analyses focus on isolated drug event pairs and may miss syndromic patterns. We applied a network- and cluster-based framework to EudraVigilance reports on antiviral use in pregnancy to improve surveillance and identify meaningful constellations. Methods: We retrieved all individual case safety reports (ICSRs) from January 2015 to June 2025, including pregnancy, puerperium, or perinatal terms, focusing on suspect antivirals. After parsing terms, disproportionality metrics were computed as a benchmark. A bipartite drug–event network was built and projected to event–event co-occurrence networks; Louvain community detection identified clusters. Clusters were characterized by size, drug mix, seriousness, overlap with disproportionality signals, and stratification across periods. Results: The dataset comprised 106,924 ICSRs and 232,067 unique pairs. Disproportionality yielded 6142 signals, mainly involving antiretrovirals (ritonavir, lamivudine, zidovudine, emtricitabine/tenofovir). Network analysis revealed clusters grouping maternal and fetal/neonatal outcomes (e.g., fetal death, low birth weight), and transplacental transfer, highlighting structures not visible in pairwise analyses. Several clusters combined high-frequency exposures with clinically relevant outcomes, suggesting early-warning potential. Conclusions: Combining disproportionality with network- and cluster-based pharmacovigilance adds value for monitoring pregnancy medication safety. Beyond individual signals, this approach reveals meaningful clusters and “bridge” reactions connecting adverse-event domains, offering a richer framework for perinatal surveillance. Despite spontaneous-reporting limits, findings generate hypotheses for mechanistic and pharmacoepidemiologic follow-up and support network methods as complements to traditional pharmacovigilance.

Background: Sotorasib, a KRAS G12C inhibitor, is approved for treating non-small cell lung cancer (NSCLC) and has shown a distinct safety profile in randomized clinical trials (RCTs). However, post-marketing pharmacovigilance is crucial to identify real-world safety signals including sex-specific differences that may not be evident in controlled trial settings. Methods: This analysis reviewed 845 individual case safety reports (ICSRs) from the EudraVigilance (EV) database between 1 January 2021, and 8 April 2025, involving NSCLC patients treated with sotorasib. Adverse drug reactions (ADRs) were assessed by sex, seriousness, outcome, and system organ class (SOC). Disproportionality analyses were conducted to detect sex-specific safety signals, and results were compared with data from the CodeBreaK200 RCT by using a two-proportion z-test. Results: Among the ICSRs, 49.2% involved male and 40.1% female patients. Serious ADRs accounted for 47.5% of cases, with females at higher risk (relative risk [RR] = 1.31; 95% confidence interval (CI): 1.22–1.40; p < 0.0001). The most frequently reported SOCs were neoplasms (15.8%), gastrointestinal disorders (15.3%), and hepatobiliary disorders (11.5%). Four sex-specific safety signals were identified: women had a significantly increased risk of cholestasis (RR = 3.37) and hepatotoxicity (RR = 3.01), while men were less likely to report decreased appetite (RR = 0.20) and rash (RR = 0.14). Real-world data showed lower reporting of diarrhea, fatigue, nausea, and liver enzyme elevations (p < 0.0001). Conclusions: Real-world pharmacovigilance supports the RCT findings and highlights sex-specific risks, thus emphasizing the importance of sex-aware monitoring and personalized toxicity management.

Background: Clinical trials comparing novel oral anticoagulants (NOACs) with warfarin reported a lower mortality rate and a reduced incidence of bleeding with NOACs. However, these studies do not allow for final conclusions about safety. Moreover, direct comparisons among NOACs are not available. Objectives: The aim of this study was to analyze data from EudraVigilance in order to compare OAC safety profiles. Methods: We searched for all suspected adverse drug reactions (ADRs) from OACs collected in the EudraVigilance up to March 2019. We calculated the reporting odds ratios (RORs) in order to assess the risk of reporting specific ADRs among drugs. Moreover, OAC safety profiles were investigated through correspondence analysis and visualized in contribution biplots. Results: A total of 244,149 individual case safety reports (ICSRs; 431,354 ADRs) related to OACs were retrieved from EudraVigilance. About 80% of ICSRs refer to NOACs, especially rivaroxaban. Gastrointestinal (Gastr) and central nervous system (Nerv) disorders were the most represented categories. More than 90% of ADRs were serious and almost 9% fatal, with the highest ROR reported for dabigatran. Both fatal and non-fatal ADRs reported for Vitamin K Antagonists (VKAs) differed from those reported for NOACs. Among the latter, dabigatran and rivaroxaban showed similar profiles, while apixaban differed from all other OACs, even in the case of fatal ADRs. Conclusions: As expected, data collected from EudraVigilance showed differences among drugs, probably related to their specific characteristics and/or the peculiar utilization in clinical practice. Further investigations are needed to better compare the safety profile of OACs. Full article

Background: This study aimed to evaluate the risk of upper gastrointestinal (UGI) adverse events (AEs) associated with oral anticoagulants (OACs) and identify potential interactions with cardiovascular (CV) drugs. Methods: Individual case safety reports (ICSRs) from the FDA Adverse Event Reporting System from July 2014 to December 2023 were analyzed. Dataset I was constructed to assess the associations between OACs and UGI AEs using disproportionality analysis. Dataset Ⅱ included OAC-related ICSRs to explore potential interactions with CV drugs through logistic regression. Positive signals were defined as potential associations identified by disproportionality analysis metrics, such as reporting odds ratios (RORs) or adjusted RORs (aRORs) accounting for confounders. Results: Dataset I included 12,905,290 ICSRs, and a positive signal for dabigatran was detected with an ROR of 1.19 (95% CI, 1.13–1.25). A total of 364,044 OAC-related ICSRs were included in dataset II. At the pharmacologic drug class level, several positive signals were identified, represented as aRORs with 95% CIs: for warfarin, amiodarone analogs (1.22; 1.04–1.43); for apixaban, angiotensin-converting enzyme inhibitors (1.34; 1.24–1.45), angiotensin receptor blockers (1.23; 1.14–1.33), dihydropyridine calcium channel blockers (1.30; 1.21–1.41), and digitalis glycosides (1.72; 1.49–2.00); and for edoxaban, angiotensin receptor blockers (1.88; 1.48–2.37), amiodarone analogs (1.73; 1.06–2.85), and anti-platelets (1.56; 1.20–2.03). No signals were observed for rivaroxaban or dabigatran. At the individual drug level, 62 OAC-CV pairs were identified as having potential interactions. Conclusions: Drug-specific interaction profiles should be considered to ensure safe and personalized use of OACs in clinical practice. Full article

Background/Objectives: Isotretinoin is a highly effective therapy for severe acne, but its potential neuropsychiatric adverse reactions (NPsRs) have been controversial. This study evaluated EudraVigilance data from 2005 to 2025 to better understand the frequency, typology, and predictors of such events. Methods: We conducted a retrospective analysis of 33,381 individual case safety reports (ICSRs) related to isotretinoin. Using descriptive statistics, chi-square tests, and logistic regression, we assessed associations between NPsRs and variables such as age, sex, geographic region, and reporter type. Results: A total of 9793 cases (29.3%) involved at least one NPsR. Depression (31%) and suicidal ideation (8.6%) were the most frequently reported symptoms. Adolescents (12–17 years) had the highest proportion of NPsR cases, while male patients and reports submitted by non-healthcare professionals were significantly overrepresented. Reports from non-European Economic Area countries also had slightly increased odds of including NPsRs. All predictors were statistically significant in the logistic regression model, though the explained variance was modest (Nagelkerke R² = 0.065). Conclusions: Neuropsychiatric reactions remain a prominent and persistent signal in isotretinoin pharmacovigilance, particularly among younger patients and non-professional reporters. Although causality cannot be inferred from spontaneous reporting data and confounding factors like acne-related depression cannot be excluded, these findings highlight the clinical value of pre-treatment psychiatric screening, patient-centered education, and proactive mental health monitoring throughout isotretinoin therapy.

Background/Objectives: Natural products with claimed adaptogenic and/or immunomodulatory effects are widely used in traditional medicine systems across Eurasia. These include herbal remedies (e.g., Panax ginseng), fungi (e.g., Ganoderma lucidum), and animal-derived substances (e.g., propolis from Apis mellifera). Despite their popularity, the safety profiles of these products—particularly concerning adverse events (AEs) and serious adverse events (SAEs)—remain insufficiently understood. This study aimed to assess the safety profiles of adaptogenic and immunomodulatory natural products through a scoping review of published human studies and an analysis of individual case safety reports (ICSRs) from the WHO-UMC VigiBase database. Methods: A scoping review was conducted using PubMed (1980–2024) in line with PRISMA-ScR guidelines. Eligible studies included randomized and non-randomized clinical trials and case reports in humans focused on safety outcomes. Data extraction followed the Joanna Briggs Institute (JBI) standardized template. ICSRs from VigiBase were analyzed by product type, AE type and seriousness, and demographic characteristics. The data were further organized to highlight the 15 most frequently reported products and their top five System Organ Classes (SOCs) and Preferred Terms (PTs). Results: The scoping review identified 51 natural products with reported adaptogenic and/or immunomodulatory properties. This included 285 clinical trials and 119 case studies on single-ingredient products and 54 clinical trials and 21 case studies on multi-ingredient preparations. Common AEs included gastrointestinal, dermatological, hepatic, cardiovascular, and immunological reactions. SAEs were rare but reported for Echinacea purpurea, Silybum marianum, and Camellia sinensis. From Vigibase, 45,042 ICSRs were retrieved for 49 natural products: 10,702 for single-ingredient and 34,340 for multi-ingredient products. Among 7856 reports listing a single-ingredient product as the sole suspect, 15.8% were SAEs, including eight fatal cases. However, the causality remained unclear due to insufficient data. Ganoderma lucidum, Viscum album, and Silybum marianum were most frequently associated with SAEs. In multi-ingredient products, propolis was frequently linked to hypersensitivity and skin reactions. Conclusions: This study provides a comprehensive overview of the safety profiles of adaptogenic and immunomodulatory natural products. Variability in product composition, lack of standardization, incomplete reporting in clinical studies, and underreporting in pharmacovigilance databases complicate accurate risk assessment. For multi-ingredient products, attributing specific AEs to specific components remains difficult. Further high-quality clinical research and improved pharmacovigilance are needed, along with clear safety warnings to reduce risks for consumers. Full article

Background/Objectives: During the COVID-19 pandemic, several antivirals were approved or repurposed, but their safety profiles have not been fully compared. Pharmacovigilance data help clarify how these drugs perform in real-world use. Methods: This study performed a comparative pharmacovigilance analysis of eight antivirals used or tested during the COVID-19 pandemic, based on individual case safety reports (ICSRs) retrieved from the EudraVigilance database, reported up to 9 February 2025 and extracted from the official platform on 12 February 2025. Adverse reactions were assessed by system organ class (SOC), demographic patterns, and seriousness, and disproportionality analysis (reporting odds ratio (ROR)) was conducted to identify potential safety signals. Results: A total of 64,776 ICSRs were analyzed. Among approved antivirals, nirmatrelvir/ritonavir (NTV/r) accounted for 13.4% (n = 8693) of reports, while remdesivir (RDV) represented 6.3% (n = 4105). Repurposed antivirals such as ribavirin and lopinavir/ritonavir dominated the dataset, together making up over 80% (n = 51,978) of all reports. RDV was associated with a high proportion of serious adverse events (84%, n = 3448), and showed consistent ROR signals in hepatobiliary, renal, cardiac, and general disorders, with values exceeding 2 in several comparisons. NTV/r displayed a milder overall profile, but with positive RORs for psychiatric disorders, gastrointestinal disorders, and product-related issues. The most affected SOCs across all drugs included general disorders (31.6%, n = 20,493), gastrointestinal (19.5%, n = 12,625), nervous system (17.8%, n = 11,511), and investigations (20.4%, n = 13,219). Demographic analysis showed that most events occurred in adults aged 18–64, with RDV more often reported in elderly patients and NTV/r more frequently associated with reports from female patients and non-healthcare reporters. Conclusions: This study highlights distinct pharmacovigilance profiles of COVID-19 antivirals and supports the role of real-world data in guiding safer therapeutic choices. Full article

Background/Objectives: Some product information on pregabalin suggests a potential risk for congenital anomalies (CAs), although evidence remains inconsistent and lacks clear patterns. This study aimed to provide additional safety information on pregabalin use in pregnancy by analyzing VigiBase, the World Health Organization’s global pharmacovigilance database of individual case safety reports (ICSRs). Methods: The analysis included de-duplicated ICSRs related to pregabalin exposure in pregnancy, collected up to 16 January 2024. Reporting odds ratios (RORs) with 95% confidence intervals (CIs) were calculated for CA categories reported in at least 10 ICSRs, with a statistical threshold defined as a 95% CI lower bound > 1. Results: Among 410 ICSRs, the majority originated from Europe (64.8%) and North America (26.5%). Of these, 59 (14.4%) ICSRs documented only pregabalin exposure in pregnancy, while 351 (85.6%) also reported adverse events in pregnancy. CAs occurred in 82 ICSRs (23.3%), most commonly involving heart defects (30), nervous system anomalies (18), and limb anomalies (12). No signals of disproportionate reporting were identified for these categories compared to the full database (heart defects: ROR 0.587, 95% CI 0.410–0.839; nervous system anomalies: ROR 0.588, 95% CI 0.370–0.933; limb anomalies: ROR 0.671, 95% CI 0.381–1.183). Conclusions: Future disproportionality analyses, along with pharmacovigilance and pharmacoepidemiological studies using patient registries and large-scale collaborative projects, are essential for the ongoing monitoring of pregabalin safety in pregnancy.

Background: Proton pump inhibitors (PPIs) are widely used for gastric acid suppression, yet their efficacy and safety in neonates and infants remain unclear. While esomeprazole is the only Food and Drug Administration (FDA)-approved PPI for neonates and infants under 1 year of age, other PPIs are also frequently prescribed. Objectives: This study utilizes FDA Adverse Event Reporting System (FAERS) data to evaluate potential adverse drug events (ADEs) of PPIs, providing crucial real-world insights into their safety in this vulnerable population. Methods: This observational cross-sectional study was conducted using an individual case safety report (ICSR) database. Only reports in neonates or infants receiving omeprazole, pantoprazole, lansoprazole, rabeprazole, or esomeprazole monotherapy were evaluated. The most frequently prescribed PPI, the most common indication, the most reported ADE, the seriousness of AEs, and the countries reporting the highest ADE number were analyzed using 2D disproportionality analyses (e.g., reporting odds ratio (RORs)). Results: A total of 464 patients were included; 323 (69.6%) of them were stated as serious and 15 (3.2%) of them were stated as time-related to mortality. Most of the ADEs were reported for lansoprazole (45.9%). The most reported PPI-associated ADE was vomiting (8.8%). According to the RORs analysis, vomiting associated with PPI monotherapy was more likely to occur (RORs: 2.88, 95% CI: 2.09–3.96), which is followed by diarrhea, hypertrichosis, choking, and erythema. Additionally, medication errors were reported in 50 (10.8%) patients. Conclusions: ICSR databases are valuable pharmacovigilance tools. The absence of access to a causality assessment is a limitation since it limits its ability to confirm whether the ADEs are truly caused by the suspected drug, mitigated using RORs analysis. Integrating neonatal-specific algorithms could enhance drug safety evaluations, strengthen evidence-based decision-making, and improve risk–benefit assessments in neonates and infants. Full article

Background/Objectives: Spinal muscular atrophy (SMA) treatment has evolved with the approval of nusinersen, onasemnogene abeparvovec, and risdiplam. This study aims to assess the post-marketing safety profile of these therapies through the spontaneous adverse drug reaction (ADR) reports available in EudraVigilance (EV). Methods: Data from EV were retrieved via adrreports.eu for the suspected ADRs associated with nusinersen, onasemnogene abeparvovec, and risdiplam from their approval in the European Economic Area (EEA) to 31 December 2024. The ADR reports were exported and analysed using descriptive statistics in Microsoft Excel. Reporting odds ratios (RORs) with 95% confidence intervals (CIs) were calculated for suspected ADRs, focusing on reactions with a lower limit of the 95% CI exceeding 1. Results: A total of 3196, 806, and 956 individual case safety reports (ICSRs) were identified for nusinersen, onasemnogene abeparvovec, and risdiplam, respectively. The most frequently reported ADRs with significantly increased RORs included post-lumbar puncture syndrome (nusinersen: 11%), pyrexia (onasemnogene abeparvovec: 23%), and pneumonia (risdiplam: 9%). While some ADRs were therapy-specific, others were consistent with SMA disease progression and complications. Onasemnogene abeparvovec showed a notable prevalence of hepatotoxicity, while risdiplam was associated with gastrointestinal and respiratory events. Conclusions: To conclude, the analysis reinforces the known safety profiles of these SMA treatments while highlighting potential areas for further investigation. ADRs related to SMA complications require careful differentiation from true drug-related effects. Future pharmacovigilance efforts should focus on long-term safety assessments and real-world evidence to optimize treatment strategies. Full article

Background: Olaparib and niraparib are poly (ADP-ribose) polymerase inhibitors (PARPi) used primarily for the treatment of ovarian cancer. While both drugs have demonstrated efficacy in clinical trials, their safety profiles, particularly in real-world clinical settings, remain to be fully elucidated. Objectives: This study aimed to (i) characterize the adverse drug reactions (ADRs) associated with olaparib and niraparib as reported in the EudraVigilance database, (ii) compare the frequency of the ADRs occurring during treatment with the two drugs, and (iii) compare post-marketing safety data with those from clinical trials. Methods: A retrospective analysis was performed using data from the EudraVigilance database (2017–2024), focusing on individual case safety reports (ICSRs) related to olaparib and niraparib. Descriptive statistics and disproportionality analysis were performed to compare the frequency and severity of reported ADRs. Results: Both olaparib and niraparib had common ADRs including nausea, vomiting, anemia, thrombocytopenia, and fatigue. However, olaparib was associated with a higher risk of myelodysplastic syndrome (MDS), acute myeloid leukemia (AML), and interstitial lung disease, while niraparib had a higher incidence of gastrointestinal events and thrombocytopenia. Our analysis demonstrates that some specific ADRs, including peripheral neuropathy with niraparib, were reported at higher frequencies compared to clinical trials. The incidence of serious ADRs, including hospitalizations and life-threatening events, was higher with niraparib than with olaparib. Conclusions: This study highlights significant differences in the safety profiles of olaparib and niraparib, with implications for clinical decision-making. Continuous monitoring and personalized management of ADRs are essential to optimize patient outcomes. Full article

Remdesivir (RDV) and nirmatrelvir/ritonavir (NMVr) are among the most widely used antivirals in the treatment of COVID-19, aiming to reduce disease severity and progression. Adverse neuropsychiatric effects, such as anxiety, sleep disturbances, and movement disorders, have emerged as significant concerns associated with these treatments. To better understand the safety profiles of RDV and NMVr, this study performs a pharmacovigilance analysis of individual case safety reports (ICSRs) from the EudraVigilance (EV) database. Objectives: This study evaluates the risk of neuropsychiatric adverse events associated with RDV and NMVr. Comparisons with other antiviral drugs, including darunavir, sofosbuvir, ribavirin, tenofovir, ritonavir, and sotrovimab, are also performed to develop a comprehensive understanding of the safety profiles. Methods: A retrospective analysis of ICSRs submitted to EV until 7 July 2024, with data extraction on 12 July 2024, was conducted. Demographic characteristics (age, sex, geographic region, and reporter type) and case severity were included in the descriptive analysis. Disproportionality analysis using reporting odds ratio (ROR) and 95% confidence intervals (CI) was performed to compare adverse drug reaction (ADRs) frequencies across 27 system organ classes (SOCs), with emphasis on “Nervous system disorders” and “Psychiatric disorders. Results: The total number of ICSRs was significantly higher for NMVr (n = 8078) compared to RDV (n = 3934). Nervous system disorders accounted for 3.07% of the total RDV reports and for 17.31% of NMVr reports, while psychiatric disorders represented 0.92% of the total ADRs reported for RDV (n = 60) and 3.61% for NMVr (n = 672). On the other hand, RDV showed a significantly lower frequency of reporting headache compared to NMVr (ROR: 0.1057; 95% CI: 0.0676–0.1653). Conclusions: NMVr presents a higher risk of neuropsychiatric ADRs than RDV, underscoring the need for enhanced monitoring, particularly in patients with preexisting central nervous system (CNS) conditions. These findings contribute to optimizing antiviral safety and informing clinical decision making. Full article

Background/Objectives: Pasireotide (PAS) is a somatostatin receptor ligand (SRL) used to treat acromegaly, a chronic condition caused by excess growth hormone. While it offers significant benefits as a second-line treatment for uncontrolled acromegaly, its use raises major concerns due to hyperglycemic side effects and gastrointestinal issues, the latter being similar to those seen with first-generation SRLs. The aim of this study is to evaluate the real-world evidence on adverse drug reactions (ADRs) reported for PAS in the EudraVigilance database, in comparison to other established drug-based therapies for acromegaly. Methods: A descriptive analysis and a disproportionality analysis were conducted. Results: The fewest individual case safety reports (ICSRs) and adverse drug reactions (ADRs) were reported for PAS, with 698 (4%) ICSRs and 1,647 (4%) ADRs, which is even lower than for pegvisomant (PEG), which had 1765 (11%) ICSRs and 4842 (10%) ADRs. Both PAS and lanreotide (LAN) exhibited the lowest proportion of cases classified as serious. Among the total reported ADRs, those categorized as “Metabolic and nutrition disorders” were most frequent and severe for PAS (PAS—17.5% vs. OCT—4.6%, LAN—4.5%, and PEG—2.7%). Additionally, PAS demonstrated a higher likelihood of reporting endocrine disorders, which were frequently classified as serious, as well as stones affecting the hepatobiliary system compared to other drugs. Conclusions: Although PAS had the fewest ICSRs and ADRs, and less frequent serious ADRs, it had more reports frequently classified as serious in the “Metabolism and Nutrition Disorders” category (including events such as elevated blood glucose levels or diabetes) and “Endocrine Disorders” category compared to other SRLs and PEG. Furthermore, there was a higher likelihood of reporting hepatobiliary stones with PAS compared to OCT and PEG. This highlights the importance of adequately monitoring glycemic control and the biliary tract through ultrasound at the initiation and during follow-up of PAS therapy. Improved monitoring and reporting of these ADRs could enhance care for patients with acromegaly. Full article

Background: Paracetamol and non-steroidal anti-inflammatory drugs (NSAIDs) are frequently used during pregnancy. Due to their fetotoxicity, NSAIDs are contraindicated during the third trimester. There is ongoing controversy about the extent to which NSAIDs may cause cardiovascular and renal impairment in the fetus earlier in the second trimester. Paracetamol, used as an effective treatment for closure of patent ductus arteriosus (PDA) after birth, is suspected to cause similar but unwanted effects during the third trimester of pregnancy. Methods: Three major pharmacovigilance databases (VigilanceCentral, EudraVigilance, and VigiBase) were searched for Individual Case Safety Reports (ICSRs; n = 1288) on fetotoxic effects that have been shown to result from NSAID exposure in late pregnancy. Results: In 219/1288 cases, an NSAID and/or paracetamol was taken after the first trimester, and the ICSR was not related to other reported risk factors. Out of these 219 ICSRs, 48 were exposed to NSAIDs in the second but not the third trimester or to paracetamol in the third trimester. Causality assessment was “probable or likely” in four NSAID reports and none of the paracetamol reports. Conclusions: The scarcity of adverse drug reactions (ADRs) in our study and in the literature, despite decades of pharmaceutical marketing and worldwide use of paracetamol as an analgesic of choice in the third trimester and the absence of formal contraindications against NSAIDs in the second trimester, speaks against a substantial cardiovascular and nephrotoxic risk of temporary use of NSAIDs in the second trimester or paracetamol in the third trimester. NSAIDs continue to be contraindicated in the third trimester. Full article
