Approved indications: Xelstrym (dextroamphetamine transdermal system) is a central nervous system stimulant approved for the treatment of attention-deficit hyperactivity disorder (ADHD) in adults and in pediatric patients 6 years of age and older; it is not recommended for children younger than 6 years.

Off-label uses: While oral dextroamphetamine is also used for conditions such as narcolepsy, the Xelstrym patch is specifically studied and labeled only for ADHD, so off-label use is uncommon and relies mainly on indirect evidence from oral formulations rather than dedicated patch trials.

Efficacy expectations:

• Many patients experience noticeable improvements in attention, organization, and reduction of impulsive or hyperactive behavior on the first effective dose, with fine-tuning of benefit over several weeks as the dose is adjusted.
• Xelstrym provides once-daily dosing with about 9 hours of wear, so the onset and offset of effect can be timed around school, work, and evening activities by choosing when to apply and remove the patch.
• Overall, its effectiveness is considered comparable to other stimulant ADHD medications when doses are properly titrated, although there are no direct head-to-head trials versus specific products such as Vyvanse or oral dextroamphetamine.

Typical dosing by age: For children and adolescents 6–17 years, the usual starting dose is one 4.5 mg/9 hr patch once daily; for adults, the usual starting dose is one 9 mg/9 hr patch once daily, with weekly dose increases in 4.5 mg steps up to a maximum of 18 mg/9 hr based on benefit and tolerability.

Special dosing instructions: In severe renal impairment, the maximum recommended dose is 13.5 mg/9 hr, and in end-stage renal disease it is 9 mg/9 hr; only one patch should be worn at a time, and Xelstrym should not be substituted milligram-for-milligram with other amphetamine products because absorption differs.

How and when to apply: Apply the patch once daily to clean, dry, intact skin on the hip, upper arm, chest, upper back, or flank about 2 hours before an effect is needed, press firmly to ensure full contact, wear it for no more than 9 hours, then remove and immediately fold it in half with the sticky sides together.

Daily use tips: Rotate application sites each day to reduce skin irritation, avoid applying to irritated or broken skin, do not cut or trim the patch, and do not place external heat sources (such as heating pads, hot tubs, saunas, or heat lamps) over the patch because heat can increase drug absorption and side effects.

Missed dose guidance: If a dose is missed, apply a patch when remembered as long as there is still time for a reasonable wear period before bedtime, but do not apply extra patches, do not extend wear time beyond 9 hours, and skip the dose if it is too late in the day.

Overdose: In suspected overdose, remove the patch immediately and seek emergency medical help or contact a poison control center, since overdose may cause severe restlessness, tremor, rapid breathing, very fast or irregular heartbeat, high fever, confusion, or loss of consciousness.

Common side effects: Decreased appetite and weight loss, trouble sleeping, headache, stomach or abdominal pain, nausea or vomiting, dry mouth, irritability, anxiety, muscle twitching or tics, mild skin irritation at the patch site, and modest increases in blood pressure and heart rate are common, especially when starting treatment or increasing the dose, and are usually mild to moderate.

Serious or rare adverse effects needing urgent attention:

• Heart and circulation problems such as chest pain, shortness of breath, fainting, rapid or irregular heartbeat, signs of stroke (sudden weakness, numbness, or trouble speaking), or painful, cold, or discolored fingers or toes.
• New or worsening psychiatric symptoms including agitation, aggression, hallucinations, paranoia, or mania, as well as seizures or severe confusion.
• Severe allergic or skin reactions such as widespread rash, blistering or peeling skin, swelling of the face or throat, or intense, spreading skin reactions under or beyond the patch area.
• Symptoms of serotonin syndrome when combined with certain other medicines (fever, sweating, shivering, confusion, muscle stiffness or twitching, fast heartbeat, or severe nausea, vomiting, or diarrhea).

Warnings and precautions: Xelstrym carries a boxed warning for abuse, misuse, addiction, overdose, and death; it should not be used with monoamine oxidase inhibitors or in people with known serious structural heart disease, and must be used cautiously in those with high blood pressure, other cardiovascular disease, psychiatric disorders (including bipolar disorder or psychosis), a history of tics or Tourette’s syndrome, or kidney impairment (dose reduction may be needed).

Pregnancy, breastfeeding, and age limits: Use during pregnancy may pose risks to the fetus and is generally reserved for situations where benefits clearly outweigh risks; breastfeeding is not recommended because dextroamphetamine can pass into breast milk, and Xelstrym is approved only for adults and children 6 years and older and is not recommended for younger children.

Comparative safety: The safety profile is broadly similar to other stimulant ADHD medicines (amphetamine and methylphenidate products), with comparable cardiovascular, psychiatric, growth, and abuse concerns, but Xelstrym adds the possibility of local skin reactions and contact sensitization from the patch.

Side-effect reporting and safety updates: Side effects should be reported to the prescribing clinician and can also be reported directly to the FDA MedWatch program (online or by calling 1-800-FDA-1088), and patients should review the current Medication Guide or prescribing information for ongoing safety updates.

Major drug interactions: Xelstrym must not be used with monoamine oxidase inhibitors (MAOIs), including linezolid or intravenous methylene blue, or within 14 days of stopping an MAOI, and combining it with other stimulants, many antidepressants (SSRIs, SNRIs, tricyclics), certain opioids (such as fentanyl or tramadol), lithium, triptans, or St. John’s wort can increase the risk of serotonin syndrome and raise blood pressure and heart rate.

Other medicines and substances: Urinary alkalinizing agents (for example some antacids or acetazolamide) can increase dextroamphetamine levels and side-effect risk, while urinary acidifying agents can decrease levels and reduce effect; tricyclic antidepressants and other sympathomimetic drugs (such as some decongestants or weight-loss products) can potentiate cardiovascular effects, and alcohol may intensify nervous system side effects and should be limited or avoided.

Supplements, foods, and tests: Caffeine-containing products and "energy" supplements can add to stimulant effects, and Xelstrym can cause a positive urine drug screen for amphetamines, so patients should inform clinicians and laboratories that they are using this medicine.

Conditions and co-medications needing caution: Extra care and monitoring are needed in people with high blood pressure, structural heart disease or other significant cardiovascular disease, hyperthyroidism, glaucoma, severe anxiety, bipolar disorder or psychosis, history of substance use disorder, kidney impairment, or a history of tics or Tourette’s syndrome.

Monitoring requirements: Before and during therapy, clinicians typically monitor blood pressure and heart rate, weight and height in children, mental health status, signs of peripheral vasculopathy (such as finger or toe color or temperature changes), skin at patch sites, and any evidence of misuse or diversion, and may obtain an electrocardiogram in patients with cardiac risk factors.

Q: What is Xelstrym used for?
A: Xelstrym is a prescription stimulant skin patch used to treat attention-deficit hyperactivity disorder (ADHD) in adults and in children 6 years of age and older.

Q: How long does a Xelstrym patch last, and can I control when it wears off?
A: Each patch is worn for up to 9 hours and is usually applied about 2 hours before the effect is needed; the effect generally fades after the patch is removed, so your prescriber can help you choose application and removal times that best fit your daily schedule.

Q: What should I do if the patch falls off or does not stick well?
A: If a patch becomes loose or falls off, do not try to reapply it; fold it in half with the sticky sides together, throw it away as directed, and apply a new patch to a different approved skin site, making sure that the total wear time for both patches that day does not exceed 9 hours.

Q: Can I shower, swim, or exercise while wearing a Xelstrym patch?
A: Normal activities such as bathing, swimming, or exercise are usually allowed, but you should check that the patch remains fully attached, avoid rubbing or exposing it to strong direct heat, and contact your prescriber if it frequently lifts or comes off.

Q: Is there a generic version of Xelstrym available?
A: As of late 2025 in the United States, only brand-name Xelstrym patches are available and there is no approved generic version.

Q: How is Xelstrym different from ADHD pills like Adderall or Vyvanse?
A: Xelstrym delivers dextroamphetamine continuously through the skin instead of by mouth, but it has similar benefits and risks to other stimulant ADHD medicines, and its dose is not directly interchangeable with oral amphetamine products, so any switch between them must be guided by a clinician.

Storage: Store Xelstrym patches at room temperature 68–77°F (20–25°C), protected from light and moisture, in their unopened pouches until use, and keep them in a secure place out of the reach of children and pets.

Handling: Open the pouch only when ready to apply, place the patch on clean, dry, intact skin, avoid touching the sticky side, wash hands with soap and water after applying or removing a patch, and avoid direct external heat sources (such as heating pads, saunas, hot tubs, or heat lamps) while wearing it.

Disposal: Prefer a drug take-back program when available; if none is available, remove each used or unused patch from its pouch and liner, fold it in half so the sticky sides stick together, and throw it away in a lidded household trash container out of reach of children and pets, and do not flush Xelstrym patches, pouches, or liners down the toilet.
