The safety of modafinil for the brain is still being investigated and debated. While modafinil is generally regarded as safe when taken as directed, there are concerns and possible dangers connected with long-term usage. Some research suggests that long-term Modalert 200 mg modafinil usage may cause alterations in brain chemistry and neurotransmitter systems, while the full scope and significance of these changes are unknown. Furthermore, there is little study on modafinil's effects on the growing brain, and its safety for usage in children and teenagers is unknown.
