Prescription Stock Finder for ADHD Meds is a startup idea for people with ADHD and patients. People with ADHD have to phone pharmacy after pharmacy to find their stimulant medication in stock, exactly the kind of executive-function task this audience struggles with most. A thread in r/ADHD drew 637 upvotes and 71 comments between Sep 14, 2026 – Oct 14, 2026. People get by with calling pharmacies manually and GoodRx (prices, not stock), and that still leaves this job open. Hotness is 4.15, Scorching. Severe, costly pain. Some willingness to pay. The thread drew 637 upvotes and 71 comments. Only clumsy or enterprise-only options. Needs integrations or data deals. A first version is a hard build, about 3–4 weeks, priced under $10 a month and charged as a free tier and a paid upgrade. The pain, the source, the alternatives, the scope notes, and the questions on this page are free to read and free to build from. The agent starter prompt is the paid part. The first slice is on the page. One credit unlocks the rest, to paste into a coding agent, download as Markdown, or send as a private link.

Market size · estimate
How big this could get
A bottom-up estimate for Prescription Stock Finder for ADHD Meds: real customer counts × a realistic price. Not a forecast.
$178M a year
3.7M adults · US adults on stimulants who could not fill a prescription in 2023
$44.2M a year
920,000 adults · smartphone users in ADHD communities who would pay for alerts
$864K a year
18,000 adults · 2% of the reachable segment in three years
What that means
18,000 adults at $4/mo = $864K ARR
Medium confidenceHow we estimated this
- Base: 3,700,000 US adults on stimulants who could not fill a prescription in 2023.
- Has the problem: 100% (all of them reported a shortage in 2023).
- Revenue per adult: $48 per year ($3.99/mo alerts).
- Reachable: 25% (smartphone users in ADHD communities who would pay for alerts).
- Three-year capture: 2% of the reachable segment.
TAM = customers with the problem × revenue per customer. SAM = the part an early product can reach. SOM = a conservative three-year share of SAM. Bars use a log scale. Shares marked “assume” are our judgment, not measured.

Is this idea already taken?
People already use Calling pharmacies manually, GoodRx (prices, not stock). Those options do not do the job in the solution above. The idea is free to build. Nothing here is an exclusive claim.
How hard is a first version?
Hard. A tight MVP is about 4 weeks (3–4 weeks), assuming the regulated or partner-gated parts are stubbed. The paid prompt turns that into tasks.
Who would pay, and how?
The audience is people with ADHD and patients. Charge a free tier and a paid upgrade, and test a price under $10 a month. Willingness to pay is one input to Hotness, not a promise that someone will buy.
Can I use the evidence?
Yes. Build the product. The thread title is a short excerpt with a link, not a quote we are putting in someone's mouth. Exact post dates and verbatim lines are added only after a manual check. Ideas are suggestions, not medical, legal, or financial advice.
