Concerta (methylphenidate) is a prescription stimulant used to manage ADHD by improving focus and attention. Because of its controlled status and risks such as dependence, misuse, and heart-related side effects, it requires medical oversight and a valid prescription. Some unverified online sellers may use marketing claims like “warranty-backed goods” to build false trust, but these are often signs of scams or counterfeit medication. Licensed healthcare providers and certified pharmacies ensure authentic medications, safe prescribing, and patient protection. Understanding Concerta’s approved uses and common scam tactics helps patients safeguard their health and safety.
