A recent study published in the Journal of the American Geriatrics Society found no association between frailty and an increased risk of adverse drug reactions among elderly patients. Instead, researchers discovered that the greatest risk factor for adverse reactions was the number of new medications recently added to a patient's regimen.
A new study published in CMAJ found that people over 65 undergoing latent tuberculosis infection therapy are at a higher risk of severe adverse reactions requiring hospitalization. The study provides age-stratified estimates of the risk of these events, accounting for comorbidities and similar health events in the general population.
The European Medicines Agency (EMA) has faced criticism for refusing to release documentation on severe adverse reactions, despite a complaint from a father who lost his son to a drug. The EMA's handling of licensing decisions and transparency is being questioned, with some experts calling for more openness.
A recent study published in the American Journal of Roentgenology found that acute adverse reactions from gadolinium-based contrast agents used during MRI are rare, occurring in only 0.16 percent of all administrations. The majority of reactions were mild, while six moderate and two severe reactions were reported.
Research finds that long-distance travel significantly increases the risk of venous thromboembolism, prompting recommendations for low-cost interventions. Stepped-dosing of efavirenz also decreases incidence and severity of neuropsychiatric adverse events while maintaining efficacy.
A major review found that only two per cent of paediatric drug trials had independent safety monitoring committees to detect adverse drug reactions. Clinical drug trials in children are essential for developing medicines and treatments, but greater safety measures and awareness are needed.
A review of over 700 pediatric drug trials found that only 13 studies had independent safety monitoring committees. The trials reported various adverse events and reactions, highlighting the need for greater safety measures and awareness in clinical trials involving children.
A Taiwanese study suggests that Four-Agents Decoction, an 800-year-old traditional Chinese herbal formula, may exhibit a beneficial effect on primary dysmenorrhea after extended treatment. However, the study did not detect significant pain reduction in the initial cycle. The authors recommend further research with larger sample sizes a...
A study by the University of Alberta finds that adverse reactions to natural health products are being under-reported, with only 1.5% of pharmacists reporting suspected events to Health Canada. The lack of data on interactions makes it difficult to provide useful advice for managing adverse reactions.
A UK study found that BBC Panorama programmes airing in 2002-04 led to a marked increase in reported adverse drug reactions for paroxetine, an SSRI used to treat depression. This effect was short-lived and less pronounced after regulatory announcements.
A study of 37,901 civilians who received smallpox vaccine between 2003 and 2004 found 822 reports of adverse events, with 100 serious cases reported. No preventable life-threatening adverse reactions were identified, highlighting the effectiveness of vaccination screening and education.
