Your prescriber's plan for you may differ based on your medical history, other medications, and individual response. Never adjust your dose or timing without explicit instruction from your prescriber.
If you've just been prescribed a stimulant medication for ADHD, your prescriber likely handed you a plan that starts low, goes slow, and involves a check-in every week or two. That process has a name: titration — finding the lowest dose that works for you with acceptable side effects.
This guide walks through what a typical stimulant titration looks like week by week. The exact numbers differ by drug, but the structure is the same across all of them.
What is stimulant titration?
Titration is the controlled process of starting a new medication at a low dose and adjusting upward in stepwise increments until you reach the therapeutic "sweet spot." For ADHD stimulants, the standard approach per clinical guidelines (NICE NG87, CADDRA) is weekly dose adjustments over 3–4 weeks, with monitoring of both symptom response and side effects at each level.
Stimulants are short-acting enough that you'll see the effect the same day you take the new dose — unlike antidepressants, where change takes weeks to emerge. That makes the feedback loop fast, but it also means side effects and benefits emerge quickly and need to be evaluated together.
Week 0 — Baseline and pre-titration evaluation
Before you take your first dose, your prescriber should establish a baseline. This usually involves:
- An initial symptom measurement (often the ASRS v1.1 — the standard adult ADHD self-report scale)
- Recording your baseline blood pressure, heart rate, and weight
- Discussing any existing sleep issues, anxiety, or other medications
- Choosing a starting dose and formulation
What you should do this week:
- Fill any questionnaires your prescriber sends you — the baseline score is what "better" is measured against
- Note your current sleep pattern and wake-up time (stimulant timing hinges on this)
- Get clear on when to take your first dose and whether to take it with food
Week 1 — Starting dose
Your first week is about safety and tolerability, not therapeutic effect. Starting doses are deliberately low:
| Medication | Typical starting dose (adults) |
|---|---|
| Vyvanse (lisdexamfetamine) | 30 mg once daily (range 20–30 mg) |
| Adderall XR (mixed amphetamine salts ER) | 20 mg once daily |
| Adderall IR (immediate-release) | 5 mg twice daily |
| Ritalin / Methylphenidate IR | 5 mg 2–3 times daily |
| Concerta (methylphenidate ER) | 18 mg once daily |
| Focalin XR (dexmethylphenidate ER) | 10 mg once daily |
What to expect:
On Day 1, you may notice a subtle shift — a bit more focus, slightly less mental noise, or just a sense of being "quieter inside." This wears off in 4–12 hours depending on the formulation. Some people feel nothing at this dose, and that's normal — you're not supposed to be at a therapeutic level yet.
Side effects in week 1 are common:
- Reduced appetite (the most universal side effect)
- Slightly elevated heart rate or feeling "wired"
- Trouble falling asleep if the dose is taken too late
- Dry mouth, mild headache, or a jittery feeling during the peak
What to log this week:
- Time you took the dose and the amount
- Energy and focus every 2–3 hours after dosing (you'll notice the curve form)
- Any side effects and when they occur
- Sleep onset and quality that night
Week 2 — First adjustment
By the second week, you and your prescriber have enough data for the first dose adjustment. The pattern is:
| Medication | Typical week 2 dose | Step pattern |
|---|---|---|
| Vyvanse | 40–50 mg | +10–20 mg weekly |
| Adderall XR | 20–30 mg | +5–10 mg weekly |
| Adderall IR | 10 mg twice daily | +5 mg per dose |
| Ritalin / MPH IR | 10 mg 2–3 times daily | +5 mg per dose |
| Concerta | 36 mg | +18 mg weekly |
| Focalin XR | 15–20 mg | +5–10 mg weekly |
What to look for this week:
- Do you notice a longer window of effect? (Vyvanse should feel like it covers most of the day by 40–50 mg)
- Has the side-effect intensity stayed the same, or intensified with the higher dose?
- Are you still falling asleep within a reasonable window?
The goal at this stage is not perfection. It's about establishing that the medication is effective and tolerable enough to continue adjusting. If side effects are too intense — particularly appetite suppression, anxiety, or cardiovascular symptoms — your prescriber may choose to stay at the current dose an extra week or try a different formulation entirely.
Weeks 3–4 — Fine-tuning
By week 3, most people are at a dose that produces noticeable symptom improvement, and the question shifts from "is this working?" to "could it work better?"
Typical therapeutic-dose range by medication:
| Medication | Adult therapeutic dose range |
|---|---|
| Vyvanse | 40–70 mg |
| Adderall XR | 20–40 mg |
| Adderall IR | 15–20 mg daily (5–10 mg per dose) |
| Ritalin / MPH IR | 20–60 mg daily (10–20 mg per dose) |
| Concerta | 36–72 mg |
| Focalin XR | 15–30 mg |
The side-effect benefit trade-off becomes clear this week:
- If 40 mg provides 70% symptom relief with mild appetite suppression, but 50 mg provides 80% relief with significant insomnia — 40 mg is probably your sweet spot.
- If 30 mg and 40 mg feel almost identical, there may be no benefit to going higher (the "ceiling effect").
- If side effects are interfering with function (you can't eat lunch, you're not sleeping, you're anxious), the dose may be too high regardless of symptom scores.
Rebound pattern: By weeks 3–4, you should be able to feel your medication's onset, peak, and wear-off clearly. The afternoon crash — a drop in energy and mood as the drug clears — is a real clinical phenomenon that is sharper on immediate-release formulations. The 4–6 PM window is when most rebound symptoms appear: fatigue, irritability, hunger, and a return of ADHD symptoms [1].
Many prescribers use this window to decide between:
- A single extended-release dose (if coverage is adequate except for rebound timing)
- A split dose (IR booster in the afternoon)
- A different formulation (e.g., switching from Adderall XR to Vyvanse for flatter pharmacokinetics)
Per-medication timeline highlights
Vyvanse (lisdexamfetamine)
Vyvanse is a prodrug — inactive until the body metabolizes it, which makes its onset and offset predictably smooth with the lowest rebound profile [2].
- Onset: 30–90 minutes
- Peak: ~3.5 hours
- Duration: 12–14 hours
- Typical titration: Start at 30 mg, adjust by 10–20 mg weekly. Many adults land at 50–60 mg.
- What to watch: Because it lasts all day, sleep effects can be a factor even at moderate doses. Take as early as practical.
Adderall XR (mixed amphetamine salts extended-release)
Adderall XR has a biphasic profile — one immediate-release bead and one delayed-release bead, giving a two-peak shape.
- Onset: 20–30 minutes
- Peak: ~5 hours (second peak around 7 hours)
- Duration: 10–12 hours
- Typical titration: Start at 20 mg. Adjust by 5–10 mg weekly. Therapeutic range 20–40 mg.
- What to watch: The afternoon dip between the first and second bead peaks can feel like wearing off, followed by re-emergence of effect. Some find this unsettling; others prefer it.
Adderall IR (immediate-release)
Immediate-release requires multiple doses per day and has the sharpest washout.
- Onset: 20–30 minutes
- Peak: ~2–3 hours
- Duration: 4–6 hours
- Typical titration: Start at 5 mg twice daily. Adjust each dose by 5 mg weekly.
- What to watch: Rebound between doses and before bed is most prominent here. Each dose wears off with a noticeable dip. The second dose timing is critical — too late and sleep suffers; too early and the afternoon gap returns.
Methylphenidate IR / Ritalin
The shortest-duration stimulant, which gives fine-grained control but the highest pill burden.
- Onset: 20–30 minutes
- Peak: ~1.9 hours
- Duration: 3–6 hours
- Typical titration: Start at 5 mg 2–3 times daily. Adjust by 5 mg per dose weekly.
- What to watch: Three daily doses mean more reminders, more scheduling friction, and three washout rebounds per day. On the upside, titration is highly tunable — you can adjust each dose independently.
Concerta (methylphenidate extended-release)
Concerta uses an osmotic-release mechanism for a flat, all-day profile.
- Onset: ~1 hour
- Peak: Biphasic — first peak at 1–2 h, second at 6–10 h
- Duration: 10–12 hours
- Typical titration: Start at 18 mg. Increase by 18 mg weekly. Therapeutic range 36–72 mg.
- What to watch: Concerta's unusual release mechanism means it can't be split or chewed. The entire tablet must be swallowed intact.
When to call your prescriber
During titration, contact your prescriber (or urgent care) for:
- Chest pain, heart palpitations, or fainting — stop the medication and seek medical attention
- Severe weight loss (more than 5% of body weight in a week)
- Suicidal thoughts — crisis resources: call 988 (US) or your local crisis line
- Hallucinations or paranoia (rare, but known stimulant adverse effect)
- New or worsening anxiety that feels unmanageable
- Allergic reaction: rash, hives, swelling
For less urgent but still meaningful signals — appetite so low you've missed multiple meals, consistent insomnia, or symptoms that feel worse than baseline — contact your prescriber before the next scheduled check-in rather than pushing through. There is no virtue in suffering through a titration schedule that isn't working.
How tracking helps
The single most useful thing you can do during titration is log what's happening as it happens. Structured logs catch approximately three times as many side effects as a general "how are you?" conversation [3] — because the human memory compresses six weeks of data into whatever mood you're in when you walk into the room.
A tracker like Titrate handles this automatically: one-tap dose logs, timed check-ins that align to your medication's pharmacokinetics, and a structured side-effect checklist. At your appointment, you hand over a report showing dose-response curves, side-effect incidence per dose level, and functional change over the entire titration window — instead of relying on what you remember.

Key takeaways
- Stimulant titration is a 3–4 week process of weekly dose adjustments — low start, incremental steps, regular monitoring
- Side effects at the starting dose are normal; the goal is finding the level where benefit clearly outweighs burden
- Each medication has a distinct pharmacokinetic profile — Vyvanse is smoothest/longest, IR methylphenidate is shortest/control-friendliest
- The afternoon rebound window (4–6 PM) is a critical diagnostic for next-dose decisions
- Logging in real time is far more accurate than retrospective recall — it's the single best thing you can do for your titration appointments
FAQ
Q: What if I feel nothing at the starting dose? That's normal. Starting doses are safety doses. Symptom relief usually appears at higher dose steps in weeks 2–3. Don't adjust upward yourself — report "no effect" at your check-in and your prescriber will increase the dose.
Q: Can I skip a dose or take extra? No. Stimulant doses are precisely timed to maintain steady coverage without stacking. Missing a dose is fine (take the next one as scheduled). Doubling up can cause dangerous blood pressure spikes.
Q: How long does it take to know if a stimulant is right for me? Most people have a clear picture by week 3–4 at their therapeutic dose. Some know by day one that it's the wrong class (side effects out of proportion to benefit). Some need 6+ weeks across multiple medications to find the right one. Both are normal.
Q: Can I drink coffee during titration? Caffeine is a mild stimulant that adds to the medication's cardiovascular load. Many people find they need less coffee or none at all. If you do, keep the amount consistent — varying caffeine confuses your titration data.
Q: What formulation gives the flattest effect? Vyvanse has the lowest rebound and longest duration. Concerta is also flat. Immediate-release formulations (IR) have the sharpest peaks and valleys. This is a comfort + coverage preference — there's no "best" one.
Q: What if I miss my check-in week? Stay at your current dose until you talk to your prescriber. Never adjust without direction. Most plans have a week of buffer built in.
