Is Mydayis the same as Adderall XR?
No. Mydayis and Adderall XR both contain the same type of amphetamine mixed salts, but they're formulated differently. Mydayis uses a triple-bead delivery system designed to last up to about 16 hours with a single morning dose, while Adderall XR is a different extended-release formulation. They are not interchangeable without a prescriber's guidance.
How long does Mydayis last and when does it kick in?
Mydayis is designed as a once-daily extended-release capsule that can provide effects for up to about 16 hours after a single morning dose, thanks to its triple-bead formulation. Because it can last well into the evening, it's meant to be taken upon awakening and not in the afternoon or evening, to avoid insomnia.
Is Mydayis a controlled substance?
Yes. Mydayis is a Schedule II (C-II) controlled substance because it's an amphetamine-based CNS stimulant with a high potential for abuse and dependence, the same category as other amphetamine and methylphenidate ADHD medications.
What is the difference between Mydayis and Vyvanse?
Mydayis contains a mix of amphetamine salts in an extended-release capsule approved for ages 13 and up. Vyvanse contains lisdexamfetamine, a prodrug that the body converts into dextroamphetamine, and has its own approved age range and dosing. Both are stimulant ADHD medications, but they are different active ingredients with different formulations, and a prescriber can help determine which fits your situation.
Can Mydayis cause weight loss or appetite suppression?
Mydayis is FDA-approved specifically to treat ADHD, not for weight loss. Appetite changes can occur with amphetamine-based stimulants as a general effect of the drug class, but Mydayis should only be used for its approved ADHD indication, and any appetite or weight changes should be discussed with your prescriber.
How much does Mydayis cost without insurance?
The price of Mydayis without insurance varies by pharmacy, dosage, and quantity. Rx.com compares cash prices at more than 60,000 US pharmacies so you can find the lowest price near you.
What are the common side effects of Mydayis?
Common side effects of Mydayis may include: Numbness or weakness in your arm or leg, or on one side of your body, pain in your lower leg, Sudden or severe headache, problems with vision, speech, or walking, Seizures, Allergic reaction: Itching or hives, swelling in your face or hands, swelling or tingling in your mouth or throat, chest tightness, trouble breathing, Anxiety, fever, muscle spasms, twitching, nausea, vomiting, diarrhea. This is not a complete list — consult your pharmacist or doctor for full side effect information.
Is there a generic version of Mydayis?
Generic versions may be available for Mydayis. Generics contain the same active ingredients as brand-name drugs and are typically 80–90% cheaper. Search Mydayis on Rx.com to compare generic and brand prices at pharmacies near you.

Looking for a Mydayis coupon? Mydayis (amphetamine mixed salts extended-release) is a brand-name, once-daily ADHD medication for adults and teens 13 and older, and this page helps you find today's cash price at pharmacies near you and compare it against the manufacturer's savings program, so you're not stuck paying full price whether you're insured, uninsured, or on Medicare.

What Is Mydayis and How Does It Work?

Mydayis is a brand-name central nervous system (CNS) stimulant in the amphetamine class, containing a mix of dextroamphetamine and amphetamine salts in an extended-release triple-bead capsule. It's FDA-approved to treat attention-deficit/hyperactivity disorder (ADHD) in adults and in children 13 years of age and older. The triple-bead design releases medication in stages so one morning dose can last up to about 16 hours, which is why it's taken once daily upon awakening rather than in divided doses. Because effects can last well into the day, Mydayis should not be taken in the afternoon or evening, as this can cause insomnia.

Mydayis Coupon vs. the Manufacturer Savings Card

Mydayis is currently only available as a brand-name product. The manufacturer offers an official copay savings program (search "Mydayis copay program" or check the packaging insert for current enrollment details, since terms and eligibility can change). Like most manufacturer copay cards, it's generally limited to people with commercial/private insurance, and it typically cannot be used if you have Medicare, Medicaid, or no insurance at all.

That's where an Rx.com cash coupon is useful: it can be used regardless of insurance status, including if you're uninsured, on Medicare, or if the manufacturer card is declined at the counter. Enter your ZIP above to see today's price at pharmacies near you, and compare that against what the manufacturer program or your insurance copay would charge.

Mydayis Alternatives: How It Compares

Mydayis is one of several stimulant medications prescribed for ADHD. Other amphetamine-based options include Adderall and Adderall XR (both also amphetamine mixed salts, in immediate-release and extended-release forms) and Vyvanse (lisdexamfetamine, a prodrug amphetamine). Non-amphetamine stimulant options in the methylphenidate class include Concerta and Ritalin, and Dexedrine is a dextroamphetamine-only stimulant. Whether any of these is a suitable substitute for Mydayis depends on your individual history and response, and switching between ADHD stimulants should only be done with your prescriber's guidance.

Mydayis Safety Information

Mydayis carries a boxed warning for high potential for abuse and dependence, a risk shared by CNS stimulants generally (amphetamines and methylphenidate); misuse can lead to serious cardiovascular events, including sudden death. It should not be combined with an MAOI or taken within 14 days of stopping one. Mydayis should be avoided in people with known structural heart abnormalities, cardiomyopathy, serious heart rhythm problems, or coronary artery disease, given the risk of sudden death, and blood pressure and heart rate should be monitored during treatment. It can also cause new or worsening psychiatric symptoms such as psychosis or mania, can lower the seizure threshold, and has been associated with peripheral vasculopathy, including Raynaud's phenomenon. Mydayis is not approved for children under 13, and long-term use in pediatric patients can suppress growth. This is general information, not medical advice — talk to your prescriber about whether Mydayis is right for you.
