Adult ADHD, Treated with Non-Stimulant Medication
ADHD in adults rarely looks like the fidgety kid in class. It looks like 15 open browser tabs and a missed deadline, 6 projects started and 1 finished, 20 minutes lost to a task that should take 2 and then 4 hours of hyperfocus on the wrong thing, chronic lateness, misplaced keys, and a running internal monologue of “why can’t I just do the thing?”
An estimated 6% of US adults, about 15.5 million people, have a current ADHD diagnosis, and about half were not diagnosed until adulthood, especially women and people whose symptoms leaned inattentive rather than hyperactive.
Inattentive, Hyperactive, or Both
Adult ADHD presents on a spectrum, and most adults show a mix of both patterns rather than one pure type.
It can look like
The inattentive side shows up as distractibility, disorganization, losing track of details, and drifting mid-conversation.
The hyperactive-impulsive side shows up as restlessness, interrupting, impulsive decisions, and a feeling of being driven by a motor.

How Siggy Treats ADHD: The Non-Stimulant Approach
Siggy treats ADHD exclusively with non-stimulant medication. That is a deliberate scope decision, and it is worth understanding what it means for you.
FDA-approved non-stimulant options include atomoxetine and viloxazine, which work on norepinephrine to improve attention, working memory, and impulse control. Alpha-2 agonists (guanfacine ER, clonidine ER) are also used, particularly when restlessness, emotional reactivity, or sleep problems are prominent; their use in adults is off-label, and your prescriber will discuss that plainly.
The tradeoffs: non-stimulants take 2 to 6 weeks to reach full effect rather than 1 hour, and for some people stimulants produce a larger symptom reduction. In exchange, non-stimulants provide steady 24-hour coverage with no afternoon crash, no rebound, no potential for abuse, and no controlled-substance refill logistics. For adults with co-occurring anxiety, a history of substance concerns, or jobs where scheduled medications are a problem, they are often the clinically preferred choice, not a fallback.

What Treatment Looks Like
Treatment starts with a structured intake that screens for ADHD along with the conditions that mimic or accompany it, including anxiety, depression, and sleep disorders. Next is a video visit with a licensed prescriber. If medication is appropriate, you can get a same-day prescription, with follow-ups scheduled through the 2-to-6-week ramp. Behavioral strategies and therapy referrals are part of the plan when they fit, because medication improves attention but does not build systems.

FAQs.
- Why doesn’t Siggy prescribe Adderall or Vyvanse?
- We prescribe non-controlled medications only. For many adults, non-stimulants are effective and better tolerated. When a stimulant is clearly the right treatment, we say so and refer you rather than fitting your care to our scope.
- Do non-stimulants actually work?
- Yes. Atomoxetine and viloxazine are FDA-approved for ADHD based on controlled trials. Effect sizes are somewhat smaller than for stimulants on average, but responses are individual, and steadier coverage matters more for some people than peak effect.
- I was never diagnosed as a kid. Can I still have ADHD?
- ADHD begins in childhood, but diagnosis often does not, especially for inattentive presentations. Your evaluation will look at long-term history, not just current symptoms.
- Could it be anxiety instead of ADHD?
- It could be either or both; the overlap is large, and the treatments differ. That is exactly what the intake and prescriber visit are designed to untangle.
