Building a Tolerance   "My 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?"   Strattera is a
relatively new medication, so we know less about it than about
other AD/HD medications. Some people do seem to adjust to a
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.
