Background: Ibuprofen is one of the most accessible non-steroidal anti-inflammatory drugs (NSADs), exhibiting non-selective reversible inhibition on COX-1 and COX-2. A series of common adverse reactions have been mentioned through the years: gastrointestinal (gastritis, ulceration, hemorrhage, or perforation), renal, hematologic, and cardiovascular. Objective: The aim of this study was to assess the real-world impact of ibuprofen regarding cardiovascular safety, utilizing an established pharmacovigilance database. Methods: Descriptive and disproportionality-based methods were used. Forty specific descriptors of cardiovascular effects were selected. Eight other NSADs and the combination of ibuprofen and pseudoephedrine were used as comparators. Results: A total of 58,760 cases were identified as being associated with ibuprofen in EudraVigilance. Stroke was reported for ibuprofen with a lower probability compared with etoricoxib (ROR: 0.34; 95% CI: 0.21–0.55), celecoxib (ROR: 0.07; 95% CI: 0.06–0.10), meloxicam (ROR: 0.25; 95% CI: 0.14–0.43), acetylsalicylic acid (ROR: 0.07; 95% CI: 0.05–0.09), and ibuprofen/pseudoephedrine (ROR: 0.11; 95% CI: 0.05–0.25). Thrombosis was reported for ibuprofen with a higher probability only relative to ketoprofen (ROR: 2.95; 95% CI: 1.71–5.09). Hypertension was reported for ibuprofen as being more probable than for acetylsalicylic acid (ROR: 1.58; 95% CI: 1.43–1.76). Myocardial infarction was reported as being more probable for ibuprofen than ketoprofen (ROR: 2.31; 95% CI: 1.57–3.40) or nimesulide (ROR: 2.43; 95% CI: 1.25–4.73). Conclusions: Overall, according to our study, the probability of reported cardiovascular adverse reactions is lower than those determined for the rest of the NSAIDs; however, taking into consideration the inherent limitations of the study, further clinical investigations would contribute to a better understanding of the cardiovascular safety of ibuprofen.

Background/Objectives: Mental health awareness is rising; thus, neurological and psychiatric side effects also benefit from increased attention from the medical and scientific community. Ibuprofen is a well-known non-steroidal anti-inflammatory drug (NSAID) that is often available over-the counter (OTC) for both adults and children, expressing good efficacy in reducing pain and fever through non-selective cyclooxygenase inhibition. As ibuprofen has already been associated with different neuropsychiatric disorders, the aim of this study was to perform an up-to-date analysis of such signals detected in the cases reported in EudraVigilance (EV). Methods: The disproportionality analysis offered a contextual insight into the real-world situation depicted in the analyzed database. Results: From the total cases reported for ibuprofen (n = 58,911), 13.9% contained nervous system disorders (n = 8214) and 10.7% entailed psychiatric disorders (n = 6295). The cases were distributed between all age groups, with a sensible higher incidence in teenagers and in women in general. Severe cases, including deaths, have been reported. By comparison with ketoprofen, acetylsalicylic acid, and diclofenac, ibuprofen presented a higher probability of reporting psychiatric and behavioral symptoms. Regarding cognitive and attention disorders and disturbances, no disproportionate signal was observed between ibuprofen and all other NSAIDs. Sleep disturbances (hypersomnia, narcolepsy and sleep paralysis) are reported as more probable for ibuprofen than for acetylsalicylic acid, naproxen, and diclofenac. A higher risk of reporting suicidal and self-injurious behaviors was noted for ibuprofen versus all other selected NSAIDs. A limitation of the study can be noted as due to suspected causality, not an established one, and EV reports cannot accurately determine adverse drug reaction frequencies. Conclusions: Considering that ibuprofen is easily accessible as an OTC drug and the higher probability of reporting several neuropsychiatric adverse effects as shown by this study, patient counseling, when possible, and general education for the public are valuable tools in managing these adverse reactions.

Background/Objectives: The objective of this study was to evaluate real-world evidence (Food & Drug Administration database, FAERS) on ibuprofen adverse events (AE) through descriptive and disproportionality analyses. Methods: Signal assessment involved analyzing the top 30 entries with the most reports. The disproportionality analysis of signals based on Evans’ criteria (number of reports > 2, chi-square > 4, and PRR > 2) was performed. A total of 70,792 reports submitted to FAERS by the end of 2024 (collected from 97 countries worldwide) indicate ibuprofen as the main suspect. Results: Of these, the highest percentage was attributed to females (n = 33,262, 47.0%) and adult patients (18–65 years) (n = 22,005, 31.1%). In the elderly group (12.4%) and in children and adolescents (11.2%), similar frequencies were reported. Oral administration was the most frequently mentioned route (n = 25,035, 35.4%). A total of 21,077 reports had an unfavorable outcome, of which 3018 (4.3%) reported death. Conclusions: The results highlight potential risks associated with ibuprofen and emphasize the importance of responsible, clinically well-founded administration. The disproportionality analysis can provide valuable information for effectively selecting drug-adverse-effect pairs that warrant further attention.
