Active ingredient: mixed amphetamine salts (immediate-release) · Generic available · Adderall is the IR form; Adderall XR is the long-acting form
Adderall is the immediate-release form of mixed amphetamine salts. Short-acting and taken multiple times a day. Used both as a primary medication and as an afternoon top-up alongside Adderall XR.
Adderall IR contains the same mixed amphetamine salts as Adderall XR (75% dextroamphetamine, 25% levoamphetamine). The difference is purely formulation: IR is a tablet that releases everything immediately; XR uses a two-phase bead system to spread the dose across the day.
Adderall IR enters your bloodstream directly. Onset within thirty to sixty minutes, peak around three hours, clears within four to six. That short window is both the strength and the weakness of immediate-release.
Why IR is still prescribed. Three reasons: more precise control over when the medication is active, easier to stop if side effects appear, and the option to top up only on the days or hours you need it. Many adults use Adderall XR as the morning anchor and Adderall IR as a controlled afternoon top-up.
Same active mixture, different release profiles.
US Adderall IR titration typically starts at 5mg taken once or twice daily and increases in defined steps. The total daily dose is usually divided across two or three administrations. Maximum US adult daily dose is 40mg.
Available US doses: 5mg, 7.5mg, 10mg, 12.5mg, 15mg, 20mg, 30mg.
Standard schedule is two or three doses spaced about four hours apart, typically morning, midday and mid-afternoon. The afternoon dose is usually smaller to avoid disrupting sleep. Most prescribers recommend the last dose no later than mid-afternoon.
Some prescriptions combine Adderall XR in the morning with an Adderall IR top-up in the afternoon. The XR provides the long anchor, the IR fills any late-day gaps. ADHDose models the combination correctly.
Adderall IR can be taken with or without food. The tablet can be split or cut, which is useful for fine-tuning dose levels during titration.
ADHDose models each Adderall dose separately and stitches them together into one continuous picture. You log each dose as you take it; the app handles the combination. The Clinician Summary export pulls 28 days of dose-time and effect data into prescriber-ready PDF for review appointments.
Adderall IR is taken two to three times daily. Each dose has its own short rise and fall. ADHDose handles every dose separately and stitches the picture together for you.
Log each Adderall dose as you take it. The app combines them into a single continuous track of where your medication is right now.
Most people tolerate Mixed amphetamine salts well, especially after the first few weeks. Here are the patterns worth noticing — and the ones that warrant a call to your prescriber.
Most ease in the first two to four weeks. Logging them daily helps you and your prescriber decide whether they are settling or sticking.
Not emergencies, but worth bringing up. ADHDose tags recurring patterns automatically in your daily logs.
Rare, but worth knowing. If you see any of these, contact your prescriber rather than stopping on your own.
The first weeks of Mixed amphetamine salts have a recognisable shape. Knowing what is normal at each stage stops you reading too much into a single bad day.
Most people feel something within the first hour of the first dose. The first few days often involve small wobbles — appetite changes, sleep shifts, occasional headaches. None of this is unusual. Daily logging helps separate first-dose nerves from real side effect patterns.
Side effects from days one to three usually start to ease. The dose-response becomes more predictable. Track focus, sleep and energy daily. This is the data your prescriber wants at your first review.
Most UK and US protocols schedule the first review around week two or four. Your prescriber will ask about effect, side effects, sleep and appetite. Bringing tracked data — rather than relying on memory — turns the review from vague impressions into something concrete.
If the first dose is not quite right, your prescriber will adjust upward in defined steps. Each step is usually held for two to four weeks before the next adjustment. The same daily logging continues.
Once the dose is settled, reviews shift to every six to twelve months. Daily logging becomes lighter — focus and sleep are usually enough. The Clinician Summary export gives prescribers a 28-day window of evidence at each review.
ADHDose makes the milestone view concrete. Daily logs of focus, sleep, energy and side effects across the titration window show the trajectory clearly — to you, and to your prescriber when review day arrives.
