Medications

Atomoxetine (Strattera)

Atomoxetine is a non-stimulant medication for ADHD, sold as Strattera. It's taken daily, it takes weeks to work, and it isn't a controlled substance.

Also known as: Strattera

What the word means

Atomoxetine is the drug. Strattera is the brand.

It’s a non-stimulant treatment for ADHD, and it works on norepinephrine rather than working like a stimulant. That difference matters in two directions. It isn’t a controlled substance, so the refill friction disappears, and misuse isn’t a concern.

But it also behaves nothing like a stimulant in practice. It’s taken every day, and it takes weeks to build an effect, rather than working within the hour. People who expect a stimulant experience from it are almost always disappointed, and knowing that in advance prevents a lot of unnecessary abandonment.

Where to read the full guide

Shrinktionary defines the word.

Read the full atomoxetine guide at PsychiatryRx, which covers what to expect, side effects, and how it compares with a stimulant.

When to seek professional care

Give it several weeks before judging it, because judging it on day three is judging the wrong thing. Tell your prescriber about new agitation, worsening mood, or thoughts of self-harm after starting or changing the dose, particularly in children and young people. If you have thoughts of harming yourself, get help right away by calling 911, or call or text 988 in the US to reach the Suicide and Crisis Lifeline.
