Non-stimulant ADHD options: when atomoxetine makes sense

Stimulants aren’t the only option. For some AuDHD adults, atomoxetine or guanfacine quietly do the job better.

When most people think "ADHD medication" they think stimulants — methylphenidate (Ritalin, Concerta) or lisdexamfetamine (Vyvanse). These are first-line for good reason: they work, fast, for about 70% of people. But that leaves a meaningful minority who either don’t tolerate them or don’t respond, and in the AuDHD population that minority is larger.

Atomoxetine (Strattera)

A selective noradrenaline reuptake inhibitor. Takes 4–6 weeks to reach full effect, works continuously (no "wearing off"), no dependence potential. Best for adults who: experience stimulant-induced anxiety, have co-occurring anxiety disorders, or find stimulants sharpen hyperfocus in unhelpful ways.

Guanfacine (Intuniv)

Originally a blood-pressure medication, now used for ADHD. Particularly useful for the emotional dysregulation and RSD that many AuDHD adults describe. Often used alongside a low-dose stimulant rather than instead of one.

What to ask your psychiatrist

If stimulants aren’t working or aren’t tolerated, ask specifically: "Given my sensory sensitivities and anxiety profile, would a non-stimulant trial be reasonable?" Most Australian psychiatrists are comfortable prescribing both; some specialise in combination therapy.
