Which drugs or supplements interact with atomoxetine?

    for example, phenelzine sulfate (Nardil) and tranylcypromine sulfate
  • Fluoxetine (Prozac),
    paroxetine (Paxil),
    quinidine, and other medications can block the enzyme in the liver that eliminates Strattera from the body. This can increase the amount of Strattera in the blood and possibly increase the risk of side effects.

Is atomoxetine safe to take if I’m pregnant or breastfeeding?

  • In some animal studies (rabbits and rats), very high doses of Strattera (6- to 23-fold higher than those that would be used in humans) were associated with lower birth weight and lower fetal survival. No adequate studies have been done in
    pregnant women. Therefore, before prescribing Strattera to pregnant women, physicians must weight the potential benefits against the potential and unknown risks.
  • Strattera is excreted in the
    breast milk of animals. Although not similarly studied in humans, it is likely that Strattera is excreted in human breast milk as well. The benefits and potential risks of Strattera therefore must be weighed before it is prescribed to
    nursing mothers.
