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.
