Building a Tolerance to ADHD Meds

“My eight-year-old son did well on Strattera for six months, but then his symptoms returned. His psychiatrist recently upped his dose — but that just made him very sleepy. Is he building up a tolerance to Strattera?”

Though the research is still unclear, some people do seem to adjust to their Strattera dose, as your son did. When this happens, a slight increase in the dose will usually work, so it might be worth waiting a few weeks to see if the sleepiness decreases. Discuss the problem with his psychiatrist.
