A PubMed search run for this page in November 2026 found no study of Adderall or Vyvanse in people with POTS, postural orthostatic tachycardia syndrome. The search for stimulants and modafinil in postural tachycardia syndrome returned 14 records, and none was a study of amphetamine or lisdexamfetamine.

The closest evidence is a randomized trial of atomoxetine, a non-stimulant ADHD medication. In 27 patients with POTS, a single dose raised standing heart rate to 121 beats per minute, compared with 105 on placebo, and symptom scores worsened.¹

Fainting, chest pain or shortness of breath on any ADHD medication is a reason to call 911 or go to an emergency department. A racing heart without those symptoms should be reported to the prescriber.

POTS itself is associated with inattention

Consensus criteria define POTS by chronic symptoms on standing with a sustained heart rate rise of at least 30 beats per minute (at least 40 in adolescents aged 12 to 19) within 10 minutes of standing, without orthostatic hypotension. About 90% of cases are female, with peak incidence from ages 13 to 29, according to a 2026 JAMA review.²

A 2009 study compared 21 patients with POTS, 18 with ADHD and 20 controls. Patients with POTS scored higher than controls on inattention and ADHD scales, and their inattention was less severe than in adult ADHD. Unlike the ADHD group, they didn't report more inattention in childhood.³

For someone whose concentration problems began with POTS, the question of ADHD medication starts with the diagnosis.

What has been studied, drug by drug

Studies of stimulant and related medications in people with POTS
Medication and study	Design	Finding
Methylphenidate (Kanjwal, 2012)	Retrospective chart review of 24 patients with severe POTS unresponsive to usual medications; no control group	14 of 18 who completed 6 months reported marked improvement; 4 had nausea and 2 stopped
Methylphenidate and other drugs (Boris, 2018)	Retrospective review at one pediatric center; 517 patients treated for fatigue or brain fog; no control group	Chart-recorded improvement ranged from 53.1% with methylphenidate to 16.5% with atomoxetine
Atomoxetine (Green, 2013)	Randomized crossover trial, single dose, 27 patients	Standing heart rate 121 vs 105 on placebo; symptoms worse
Modafinil (Kpaeyeh, 2014)	Randomized crossover trial, single dose, 54 patients	Standing heart rate not significantly different from placebo; seated systolic pressure 109 vs 104 mm Hg; symptom scores not significantly different

In both methylphenidate studies, patients received the drug to treat POTS symptoms, and neither studied people with diagnosed ADHD. Improvement was judged from charts, without a control group.^{4, 5} The 77% figure from the first study refers to 14 of the 18 who completed 6 months, out of 24 who started.⁴

The authors of the modafinil trial noted concern that stimulant medications "may worsen the tachycardia associated with POTS".⁶

The atomoxetine authors concluded that medications that raise standing heart rate "should likely be avoided" in POTS. They added that stimulants "are likely to also be poorly tolerated in POTS for similar reasons", an inference, since no stimulant was given in that trial.¹

What the Heart Rhythm Society consensus says

The 2015 Heart Rhythm Society expert consensus statement says: "Drugs that block the norepinephrine reuptake transporter can worsen symptoms in patients with POTS and should not be administered." It's a Class III recommendation, level of evidence B-R.⁷ Atomoxetine, the drug in the trial above, was tested as a norepinephrine reuptake inhibitor.¹

The statement doesn't mention methylphenidate, amphetamine or stimulants. It notes that modafinil "can worsen the symptoms of tachycardia."⁷

A 2025 systematic review covered 21 randomized trials with 750 patients from 2000 to 2023. The abstract's list of medications tested includes atomoxetine and modafinil and does not include methylphenidate or any amphetamine. The authors described POTS as lacking a definitive treatment strategy, with weak evidence behind the 2015 and 2020 guidelines.⁸

Can ADHD medication cause or mimic POTS?

The 2026 JAMA review lists medication effects, "eg, stimulants, norepinephrine reuptake inhibitors, and diuretics", among causes of a fast heart rate to exclude before diagnosing POTS.² A 2016 report of two cases noted that stimulant medication "may mimic the tachycardia" of POTS.⁹ No source cited here shows ADHD medication causing POTS as a lasting condition.

The Vyvanse label describes an average heart rate rise of about 3 to 6 beats per minute, with larger increases in some patients, and the Adderall XR, Vyvanse, Concerta and Ritalin labels don't mention POTS.^{10, 11, 12, 13} I've covered the general heart rate effects in effects of ADHD medication on the heart.

Deciding on ADHD treatment with POTS

None of the studies enrolled people with both ADHD and POTS, and none addresses dose or long-term use. A decision to start, continue or change ADHD medication with POTS is made with the prescriber, and the clinician treating the POTS should know about it.

Limitations of the evidence

This evidence has limitations. First, the two randomized trials each gave a single dose and observed patients for hours, and the methylphenidate data come from uncontrolled chart reviews with subjective outcomes. Second, no study found tested amphetamine or lisdexamfetamine in POTS. Nevertheless, the one randomized trial of an ADHD medication in POTS cited here showed higher standing heart rate and worse symptoms, and the consensus statement advises against that drug class.

For someone with both conditions, the cited evidence speaks mainly to standing heart rate and symptoms, and decisions about ADHD medication are made with the prescriber.

Frequently asked questions

Can you take Adderall with POTS?

A November 2026 PubMed search found no study of Adderall in POTS: it returned 14 records on stimulants in postural tachycardia syndrome, and none studied amphetamine. The 2015 Heart Rhythm Society statement doesn't mention stimulants, so the decision is made with the prescriber.⁷

Can Adderall make POTS worse?

No study found in this page's November 2026 search tested it. In a randomized trial of 27 patients with POTS, a single dose of the non-stimulant atomoxetine raised standing heart rate to 121 beats per minute, compared with 105 on placebo, and worsened symptoms; the authors wrote that stimulants are likely to be poorly tolerated for similar reasons.¹

Does Adderall help POTS?

None of the studies found tested amphetamine. For methylphenidate, a chart review of 24 patients with treatment-resistant POTS found that 14 of 18 who completed 6 months reported marked improvement, with no control group.⁴

Can ADHD medication cause POTS?

A 2026 JAMA review lists stimulants and norepinephrine reuptake inhibitors among medication effects to exclude before diagnosing POTS, and a 2016 report of two cases described stimulant medication mimicking its tachycardia. No source cited here shows ADHD medication causing POTS as a lasting condition.^{2, 9}

What is the best ADHD medication for POTS?

None of the sources cited compares ADHD medications in people with POTS. The one non-stimulant tested in the studies cited here, atomoxetine, raised standing heart rate and worsened symptoms after a single dose, and the Heart Rhythm Society says norepinephrine reuptake transporter blockers should not be administered in POTS.^{1, 7}

Chest pain, fainting, or shortness of breath during treatment needs immediate medical assessment. Call 911 or go to the nearest emergency department for severe symptoms. Medication changes are made with the prescriber.
