Stimulant medications can be very effective in reducing symptoms of ADHD, but some kids do experience uncomfortable or harmful side effects. When side effects become a problem, we try to change the dosage, the release formula, or the type of medication your child is taking. The goal is to determine what will give him the most benefit, with the least side effects.
The key problems to be on the lookout for:
Sleep problems
If medication keeps your child awake, it may still be active at bedtime. A short-acting formula taken too late or a long-acting one might be the issue—consider trying a shorter duration option. Sleep problems often improve within 4–6 weeks as children adjust to medication. Bedtime stimulation like computer use could also be contributing.
Eating changes
Extended-release medicines can affect appetite, often peaking about four hours after being taken. Encourage your child to eat when hungry—before the medicine kicks in at breakfast and as it wears off in the evening. If appetite loss is a concern, consider medication breaks on weekends or switching to immediate-release tablets.
Delayed growth
Stimulant medication may slow boys' growth in the first year, but studies show they catch up by the second or third year. Boys who take weekend or summer breaks often avoid this issue. Girls are not affected.
Nausea and headaches
These problems tend to dissipate within a few weeks of beginning medication, and can be minimized by having your child take the medication with food, and in some cases by changing the dosage or schedule.
Rebound effect
Some kids experience a “rebound effect” of irritability and aggression when medication wears off quickly. To ease this, a smaller dose before rebound may help. Rebound can also signal a too-high dose, a poor fit with the medication, or underlying issues like anxiety or mood disorders that need attention.
Tics
Some children develop tics on stimulant medication. Switching to another stimulant or a non-stimulant may help. Non-stimulants, though less potent, are less likely to cause tics.
