Any product that is released to the market may acquire a "Market Complaint" if it does not fulfill the needs of the consumer or if it contains serious flaws. For example, it might be a product from any industry, such as fast moving consumer goods, technological devices, cosmetics, or pharmaceuticals. When it comes to therapeutic products, the greatest quality and efficacy are required. A product is safe and effective if it satisfies certain critical criteria in terms of metrics such as safety, identity, strength, purity, and quality. In everyday life, a pharmaceutical product may face a market complaint. Unlike any other product, the user in this situation is a patient, thus the effect and ramifications are different.
