Yes, generic Adderall is available in both immediate-release tablets and extended-release (XR) capsules. The generic has been on the market for years, costs significantly less than the brand name, and is carried by most pharmacies. However, ongoing supply shortages that began in late 2022 have made filling prescriptions for any version, generic or brand, consistently difficult through 2025.
What Generic Adderall Actually Is
The generic name is a mouthful: dextroamphetamine saccharate, amphetamine aspartate, dextroamphetamine sulfate, and amphetamine sulfate. You’ll often see it listed on pharmacy labels as “mixed amphetamine salts” or “amphetamine salts combo.” The formulation contains two types of amphetamine (d-amphetamine and l-amphetamine) in a 3:1 ratio, identical to the brand-name product. Each tablet or capsule splits its total dose equally across the four salt forms, so a 20 mg tablet contains 5 mg of each.
The FDA requires generics to contain the same active ingredients in the same amounts and to release the drug into your bloodstream at the same rate as the brand. Where generics can differ is in inactive ingredients: fillers, binders, dyes, and coatings. For most people this makes no practical difference, but a small number of patients notice changes in how a medication feels when switching between manufacturers. This is worth knowing if your pharmacy changes suppliers.
Available Forms and Strengths
Generic Adderall comes in two forms:
- Immediate-release tablets typically last 4 to 6 hours and are taken two or three times a day. They’re available in 5 mg, 7.5 mg, 10 mg, 12.5 mg, 15 mg, 20 mg, and 30 mg.
- Extended-release capsules (XR) are designed to last roughly 10 to 12 hours with a single morning dose. They come in 5 mg, 10 mg, 15 mg, 20 mg, 25 mg, and 30 mg. The authorized generic XR entered the market in April 2009.
Multiple manufacturers produce both forms, which is why the pill you get may look different from month to month. The color, shape, and markings change depending on the maker, but the active medication inside meets the same FDA standard.
Cost: Generic vs. Brand Name
The retail (cash) price for brand-name Adderall runs around $211 for a 30-day supply, though this varies by strength and pharmacy. Generic versions typically cost substantially less, often 50% to 80% lower without insurance. With insurance or a discount card, many people pay under $30 for a generic fill.
Prices can shift depending on the strength you’re prescribed and whether you take immediate-release or XR. Most insurance plans and pharmacy benefit managers automatically cover the generic and require it unless your prescriber specifically writes “dispense as written” for the brand. If you’re paying cash, asking your pharmacist to check prices across manufacturers can sometimes save an additional few dollars, since different generic makers price their products differently.
The Ongoing Shortage Problem
Having a generic on the market doesn’t guarantee you can fill your prescription easily right now. The FDA first posted an official shortage of mixed amphetamine salts in October 2022, and that shortage persists as of May 2025. Lisdexamfetamine (the active ingredient in Vyvanse) and methylphenidate (Ritalin, Concerta) are also affected, meaning the problem spans nearly all major ADHD medications.
The numbers paint a stark picture. Roughly 6% of U.S. adults now carry an ADHD diagnosis. About half of them take medication, and among those, 71.5% reported difficulty filling their prescriptions in 2023. That’s not a minor inconvenience for a controlled substance you can’t stockpile: most states limit prescriptions to 30-day supplies with no refills, so a missed fill means a gap in treatment.
If your pharmacy can’t fill your prescription, there are a few practical steps that help. Call ahead before showing up. Ask your pharmacist to check inventory at other locations in their chain. Independent pharmacies sometimes have better luck sourcing from smaller distributors. Your prescriber can also adjust the specific strength or manufacturer if one version is more available than another, though any change to a Schedule II prescription requires a new written order.
Switching Between Generic and Brand
In most states, pharmacists are allowed (and often required) to substitute a generic when one is available, unless the prescriber explicitly requests the brand. If you’ve been stable on one version and your pharmacy switches you to a different generic manufacturer, pay attention to how you feel over the first week. The active drug is the same, but differences in inactive ingredients can occasionally affect absorption timing for some people.
If you notice a meaningful change after a switch, talk to your prescriber. They can write the prescription specifying a particular manufacturer or request “dispense as written” for the brand. Keep in mind that requesting the brand name will almost always cost more out of pocket, and your insurance may require prior authorization to cover it.
