Pharmacovigilance reporting and monitoring systems play an essential role in identifying, assessing, understanding, and preventing adverse effects associated with medicines. These systems support healthcare professionals, regulatory authorities, and pharmaceutical organizations by collecting and evaluating safety information throughout a product's lifecycle. Effective monitoring helps detect potential risks early, promotes patient safety, and contributes to informed healthcare decisions. Reporting systems also support regulatory compliance while improving confidence in medication use. Understanding how pharmacovigilance systems operate provides valuable insight into drug safety practices and the continuous efforts made to maintain the quality, effectiveness, and safe use of pharmaceutical products worldwide.
