Is Modalert bad for your brain?

Modalert (Modafinil) is generally considered safe for the brain when prescribed for conditions such as narcolepsy, sleep apnea, and shift work sleep disorder. It works by stimulating certain neurotransmitters, promoting attention, and improving cognitive function. However, irresponsible use of Modalert or high doses, especially for unapproved cognitive enhancements, may pose risks. Some users have reported side effects such as headaches, anxiety, mood swings, and irritability. Long-term use without medical supervision may disrupt natural sleep patterns and impair brain function. Modalert is not inherently "bad" for the brain, but it is important to use it responsibly and under medical supervision to avoid potential adverse effects.
