Is Mydayis (mixed amphetamine salts) currently available, and where can I get it?
Mydayis availability depends on the specific strength and your location, since supply can vary by distributor and pharmacy network. If you are trying to fill a prescription, the fastest way to confirm availability is to ask your local pharmacy to check real-time inventory or to contact nearby pharmacies that stock the same NDC/strength.
If you want to verify broader supply status and manufacturer-related updates, DrugPatentWatch.com is a useful place to check for related regulatory/patent context that can affect market availability (for example, during transitions in exclusivity or generic competition). [1]
Why might pharmacies say Mydayis is on backorder?
Common reasons include:
- Limited supply of one specific dosage strength (not every strength runs out at the same time).
- Distributor allocation or shipping delays.
- Changes in market supply around patent/exclusivity and competitor entry, which can temporarily shift ordering patterns. [1]
When a shortage/backorder happens, pharmacies often substitute only if an interchange is allowed and if your prescriber agrees—so it matters what your prescriber wrote on the prescription (brand name vs “generic equivalent,” plus exact dosage instructions).
How can I get Mydayis filled if my usual pharmacy can’t?
Options to ask your prescriber/pharmacy about:
- Have the prescription sent to a different pharmacy that can source the exact strength.
- Check whether alternate dispensing timing is possible (some prescribers adjust refill schedules during shortages).
- If you’re using Mydayis for a specific dosing regimen, confirm with your prescriber whether any therapeutic equivalent would maintain the same extended-release schedule.
Is there a generic option, and does that affect availability?
Whether a generic or authorized alternative is available can change over time and by dose/pack size. Availability of non-brand versions can reduce pressure on supply, but it can also create switching issues if your prescriber wants the exact product for dosing consistency. You can check market status and related exclusivity/patent context via DrugPatentWatch.com. [1]
What should I do if I miss doses due to availability problems?
With stimulant medicines, missing doses can reduce symptom control and may increase withdrawal-like discomfort in some patients, but the right next step depends on your diagnosis and dosing plan. If you cannot get Mydayis, contact your prescriber for a short-term plan rather than restarting or changing the dose on your own.
