Adult ADHD medication falls into two groups. Stimulants, which are methylphenidate or amphetamine-based, work within hours and have the strongest evidence. Non-stimulants, atomoxetine and viloxazine, take longer to build up but aren’t controlled substances. A prescriber chooses between them based on your heart, sleep, anxiety, any history of substance use, and how quickly you need relief.
Most guides stop at a list of drug names. This one is written from the prescriber’s side: what gets weighed before the first prescription, how doses change over the first weeks, and how refills work under New Jersey and New York rules. If you live in either state, Gimel Health offers ADHD medication management in NJ and NY with Michael Feldman, PA-C.
Stimulants and Non-Stimulants: The Two Groups of Adult ADHD Medication
Stimulants are the first-line group for most adults. They include methylphenidate (Ritalin, Concerta, Focalin) and amphetamine-based medications (Adderall, Vyvanse), all of which are Schedule II controlled substances. Two non-stimulants are FDA-approved for adults: atomoxetine (Strattera) and viloxazine (Qelbree). Both act on norepinephrine, and neither is a controlled substance.
In 2018, a network meta-analysis led by Samuele Cortese in The Lancet Psychiatry (Comparative efficacy and tolerability of medications for ADHD) pooled 51 randomized trials in adults, with 8,131 adults in the efficacy analysis. Amphetamines and methylphenidate both outperformed placebo, and the authors named amphetamines the preferred first choice for short-term treatment in adults. Atomoxetine also beat placebo, but adults tolerated it less well than placebo.
That doesn’t make non-stimulants a second-class option. For some adults they’re the better fit from the start, and that’s where the prescriber’s judgment comes in.
How Does a Prescriber Choose Between Them?
Your health history matters more than which drug is “strongest”. Before a first prescription, Michael Feldman, PA-C, weighs four things, along with practical details like how many hours of coverage your workday needs:
- Heart history. Stimulant labels advise checking for heart disease first, including a family history of sudden death or arrhythmia, and avoiding stimulants in people with serious heart conditions.
- Sleep. Insomnia is one of the most common stimulant side effects. Someone who already sleeps badly may do better on a shorter-acting dose taken earlier in the day, or on a non-stimulant.
- Anxiety. Some adults feel more anxious on a stimulant at first. Others find their anxiety eases once ADHD is treated. Either way, it gets watched rather than assumed.
- Misuse risk. In 2023, the FDA required an updated boxed warning on all prescription stimulants covering misuse, abuse and addiction, and told prescribers to assess that risk before prescribing. A history of substance use disorder often tips the decision toward a non-stimulant.
Other diagnoses change the picture too. If bipolar disorder is part of your history, the order of treatment changes entirely. The post on ADHD vs bipolar disorder explains why.
Starting Dose and Adjusting It
ADHD medication starts low and goes up in steps, usually about a week apart. Lisdexamfetamine (Vyvanse) is a typical example: its FDA label on DailyMed starts at 30 mg each morning and adjusts by 10 or 20 mg roughly weekly, up to 70 mg. Viloxazine’s prescribing information starts adults at 200 mg daily and rises by 200 mg weekly, up to 600 mg.
The target isn’t the highest dose you can tolerate. It’s the lowest dose that makes a real difference at work and at home, with side effects you can live with. Stimulants act the same day, so dose changes can move fairly quickly. Atomoxetine and viloxazine build up over several weeks, so it takes longer to tell whether a dose is working.
Expect follow-ups every few weeks while the dose is being set, then less often once it’s stable. Why so many visits early on? Because each change has to be checked before the next one is made.
Side Effects to Report
The most common stimulant side effects in adults are decreased appetite, trouble sleeping and dry mouth. In lisdexamfetamine’s adult trials, each affected about a quarter of patients, compared with 2% to 8% of people taking a placebo. The same label notes that stimulants raise blood pressure by about 2 to 4 mm Hg and heart rate by about 3 to 6 beats per minute on average.
For viloxazine, the most common adult side effects listed are insomnia, headache, sleepiness, fatigue, nausea, decreased appetite, dry mouth and constipation. Tell your prescriber promptly about:
- chest pain, fainting or a racing heart (get urgent care for these)
- new or worsening anxiety, agitation or mood swings
- low mood or thoughts of suicide, especially on a non-stimulant: viloxazine carries a boxed warning for suicidal thoughts and behaviors, and atomoxetine carries a similar one
- sleep problems that haven’t settled after the first couple of weeks
- weight loss or skipped meals because you’re never hungry
Most side effects are manageable with a change in dose, timing or medication. They’re information for your prescriber, not a reason to quietly stop taking it.
Refills and Controlled-Substance Rules in NJ and NY
Stimulant prescriptions can’t be refilled. Under federal rule 21 CFR 1306.12, every Schedule II fill needs a new prescription. A prescriber can issue several dated prescriptions covering up to 90 days, where state law allows it. Non-stimulants like atomoxetine and viloxazine aren’t controlled, so their refills work like any routine prescription.
New York adds its own layer. Most prescribers must check the state’s Prescription Monitoring Program Registry before prescribing a Schedule II, III or IV drug. New York Public Health Law § 3332 generally limits a controlled-substance prescription to a 30-day supply, with longer supplies allowed only for conditions the state lists. New Jersey runs its own prescription monitoring program, which records the stimulants dispensed in the state.
In practice, plan your follow-ups around your supply, and ask for the next prescription several days before you run out rather than on the day. Expect early requests to be questioned: the FDA specifically tells prescribers to watch for renewals requested more often than the dose would need. And if you’re wondering whether a physician assistant can write these prescriptions at all, the post on who can prescribe ADHD medication in NJ and NY covers the credential side.
When to Book an Evaluation
Book an evaluation if problems with attention, organization or impulsivity have been with you since childhood and are getting in the way at work, at home or in relationships. The National Institute of Mental Health notes that medication and therapy are the most effective treatments for ADHD. Medication starts with a diagnosis, not a request for a particular drug.
Not sure it’s ADHD? The free adult ADHD self-screener takes a few minutes and gives you something concrete to bring to the appointment. What happens in the evaluation itself is covered in what an adult ADHD evaluation involves.
At Gimel Health, Michael Feldman, PA-C, treats adults, adolescents and children who live in New Jersey or New York, from the office at 440 West St, Suite 307, Fort Lee. The initial evaluation is $350 for up to 50 minutes, and follow-ups are $300 for up to 25 minutes. A free discovery call of about 10 minutes comes first so you can check it’s the right fit. Care is self-pay, a superbill is provided, and how much your insurer reimburses depends on your plan. Appointments are typically available within 1 to 2 weeks, in English, Russian or Hebrew. A first prescription for a controlled medication may need an in-person visit in Fort Lee, and you’ll be told if that applies when you book.
