Attention deficit hyperactivity disorder (ADHD) is a fairly common psychiatric disorder among children. It has substantial consequences in terms of quality of life for those experiencing it and their families. In managing ADHD symptoms medication plays an essential role, including stimulants such as methylphenidate being a key component. Nevertheless, concerns have been raised about possible adverse reactions connected to these drugs. Thus, in this systematic review, an extensive analysis was conducted aiming at understanding any negative repercussions specifically from prolonged exposure to these medications among patients diagnosed with ADHD. The methodology entailed adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines. While capturing relevant data through a meticulous search in various databases, filtered according to preset inclusion and exclusion criteria, 13 studies were considered for analysis. Conclusions indicate that the administration of stimulant medications can potentially translate into a small rise in blood pressure along with increased heart rate particularly when amphetamines are taken. However, no reports of notable serious cardiovascular events have emerged. In the domain of neuropsychiatry, it appears that long-term usage of methylphenidate generally bears no serious consequences, even though a hike in risk levels related to the occurrence of psychotic episodes was detected among those treated with amphetamines. Several gastrointestinal side effects including decreased appetite and stomach pain were reported, however, findings regarding ocular abnormalities or growth-related effects stood inconclusive. Therefore, based on this data the consensus is that stimulant medications do generate manageable and mild negative outcomes within the ADHD population. It is vital however to highlight the need for careful observation and further scientific inquiry to achieve a better grasp on both immediate as well as long-term implications involved.
