What is one of the common side effects of stimulant medications used for ADHD?

Stimulant medications used for Attention-Deficit/Hyperactivity Disorder (ADHD), such as methylphenidate and amphetamines, often lead to insomnia as a common side effect. These medications work by increasing the levels of certain neurotransmitters, including dopamine and norepinephrine, which can enhance alertness and focus. However, this stimulating effect can interfere with the ability to fall asleep or stay asleep, resulting in insomnia.

This side effect is particularly relevant in the context of patient management, as it may necessitate timing adjustments in the medication schedule or exploring non-stimulant alternatives if sleep disturbances become problematic.

The other options do not accurately reflect typical side effects associated with stimulant medications for ADHD. Increased appetite is generally contrary to what many patients experience; instead, stimulant use often leads to a decrease in appetite. Increased mood stability is not a recognized effect associated with stimulants; rather, mood fluctuations might occur in some patients. Thus, insomnia stands out as a significant and common concern in this therapeutic context.
