Can ADHD Medications Affect Growth?

Some research studies reveal that stimulants might slightly delay growth in the first one or three years of medication use.

Research Findings

  • Growth alterations are minor in most cases.
  • Most teenagers have a compensatory growth spurt at a later age.
  • Routine assessment of height and weight is advised.
  • Medication advantages outweigh potential risks.

Height and weight assessments are common practices among healthcare professionals.

Loss of appetite is another common problem experienced mostly with stimulant drugs.

Appetite Tips

  • Serve your child high-calorie snacks right after school.

Tips for Healthy Sleeping

  • Take the medication strictly as per instructions.
  • Try not to use stimulants late in the afternoon or evening.
