If you’ve been diagnosed with ADHD as an adult, or you’re considering an evaluation, medication is often part of the conversation. There are several ADHD medication options for adults, and they work in different ways, with different side effects and practical considerations. This guide explains stimulants vs non-stimulants, what to expect when starting, how shortages and telehealth rules affect care, and how psychiatrists choose among options.
How Common Is ADHD Medication Use in Adults?
ADHD is common in adults, and many use medication. According to a CDC report, an estimated 15.5 million U.S. adults, or 6.0%, had a current ADHD diagnosis in 2023, and approximately one-third of adults with ADHD took a stimulant medication in the previous year. About half had used telehealth for ADHD-related services.
Access has been a challenge. The same report found that 71.5% of adults taking a stimulant for ADHD had difficulty filling a prescription because the medication was unavailable.
Among adults with ADHD who took a stimulant in the previous year, the share who had difficulty filling a prescription due to unavailability.
Stimulants vs Non-Stimulants
The main difference in stimulants vs non-stimulants is that stimulants, such as methylphenidate and amphetamine-based medications, usually work within hours and are often the first choice, while non-stimulants, such as atomoxetine, take weeks to build up but don’t carry the same misuse risk or controlled-substance rules.
| Stimulants | Non-stimulants | |
|---|---|---|
| Examples | Methylphenidate, amphetamine-based medications | Atomoxetine and others |
| How fast they work | Within hours | Over several weeks |
| Controlled substance? | Yes | No |
| Often considered when | First-line for many adults | Stimulants aren’t suitable or preferred |
Stimulants come in short-acting and long-acting forms. Long-acting forms can provide smoother coverage through the day and may carry lower misuse risk. Non-stimulants may suit people with certain heart conditions, a history of substance use, anxiety that worsens on stimulants, or those who prefer to avoid controlled substances.
Common ADHD Medication Side Effects
Common ADHD medication side effects include reduced appetite, trouble sleeping, headache, dry mouth, irritability, increased heart rate, and slightly raised blood pressure, and many can be managed by adjusting the dose, timing, or formulation. Non-stimulants can cause nausea, fatigue, or sexual side effects in some people.
- Appetite: eating a good breakfast before a dose can help.
- Sleep: taking stimulants earlier in the day often reduces insomnia.
- Heart and blood pressure: these are checked before and during treatment.
- Mood: irritability or a crash as a dose wears off can often be adjusted.
The best ADHD medication is the one that helps you function well with side effects you can live with, and finding it can take some adjusting.

ADHD Medication Shortages and What to Do
ADHD medication shortages have made it hard for many adults to fill prescriptions, and practical steps such as calling pharmacies ahead, being flexible about formulation or strength, and talking with your psychiatrist about alternatives can help. Don’t change doses on your own; your psychiatrist can adjust the plan safely.
If a shortage interrupts treatment, a temporary switch to another stimulant, a different formulation, or a non-stimulant may be an option. Planning ahead before refills run out makes those changes easier.
Telehealth ADHD Prescriptions in 2026
Telehealth ADHD prescriptions for stimulants are currently allowed without a prior in-person visit under temporary federal flexibilities, which the DEA extended through December 31, 2026. The Department of Health and Human Services said the extension is meant to keep care accessible for patients who rely on telemedicine, including those receiving mental health treatment. Rules may change after that date, and your psychiatrist will explain what applies.
Non-stimulant ADHD medications aren’t controlled substances, so they follow standard prescribing rules. Our walkthrough of how telepsychiatry works explains video visits.
- Start low. Begin with a low dose and increase gradually.
- Track effects. Note focus, organization, sleep, appetite, and mood each day.
- Check vitals. Blood pressure and heart rate are monitored.
- Adjust timing. Change dose timing or formulation to fit your day.
- Plan refills. Request refills early, especially during shortages.
