Loss of appetite
Some medications used to treat ADHD can often cause a loss of appetite. However, this is a mild side effect that remits when the patient stops taking the treatment.
What is the relationship between ADHD treatment and loss of appetite?
Some medications used to treat ADHD can often cause a loss of appetite. If the loss of appetite is sustained over time, this may lead to weight loss and slower physical growth.
Short studies lasting a few weeks or months have shown that up to half of ADHD patients may experience this adverse side effect. The frequency of this happening is 4 to 5 times higher than in patients not receiving active treatment. However, this side effect usually improves when the treatment dose is reduced, and remits when treatment is withdrawn.
