ADHD Medication Dose Adjustment: What to Track

You've been on 10mg for two weeks. Some days feel sharper. Other days feel exactly like before. Your next appointment is in three weeks and you have no idea what to tell your psychiatrist — or whether what you're experiencing even warrants a conversation about changing the dose.

This is the most common stuck point in ADHD medication titration. Not knowing whether the dose is working, and not having the evidence to make the case either way. ADHD medication dose adjustment isn't something your prescriber can do well on vibes — they need data. Here's how to build it.

How Long Should You Stay on a Starting Dose?

Most psychiatrists want at least two to four weeks of data at a stable dose before considering an adjustment. That window exists for a reason: stimulant medications need time to reach a consistent pattern in your system, and early side effects often settle as your body adjusts.

The key word is "stable." If you've only taken the medication inconsistently, or if you're still in week one, the fluctuations you're feeling are probably noise, not signal. Two weeks of consistent daily use — same time, same dose — is the minimum data set for a meaningful conversation.

What the two-week window actually tells you:
- Side effects that haven't faded by day 14 are likely to persist at this dose
- If you haven't noticed any difference in focus or energy by day 10–14, the dose may be too low
- If you feel benefits in the morning but crash by early afternoon, that's a duration problem — not necessarily a dose problem

Signs the Dose May Be Too Low

A dose that's too low doesn't always feel like nothing. Sometimes it feels like the medication works for an hour and then disappears. Sometimes it holds on easy days but falls apart the moment you need sustained concentration.

Specific patterns that suggest under-dosing:

Short effective window. You feel the medication kick in, but it wears off after two to three hours instead of the expected four to six for IR formulations, or eight to ten for XR. You're watching the clock waiting for a second wave that never comes.

Effect only on low-demand tasks. You can handle email fine, but the moment you need to write something complex or hold a long meeting, the support evaporates. A therapeutic dose should hold across moderate cognitive demand, not just easy tasks.

Baseline returns fully by midday. If by noon you feel exactly like pre-medication — same difficulty starting, same task-switching cost, same wall — the dose likely isn't reaching a sustained therapeutic level.

No functional difference on high-demand days. If you genuinely can't tell whether you took it on a day with back-to-back demands, that's a data point worth writing down.

Signs the Dose May Be Too High

Higher isn't always better. Signs that the current dose may be overshooting your threshold:

Jitteriness or chest tightness that doesn't fade after week one. Some early stimulant anxiety settles. Persistent physical agitation past two weeks suggests the dose may be past your threshold.

Tunnel vision without flexibility. Some people describe being over-medicated as feeling locked onto one task, unable to shift even when they need to. This is different from productive focus — it feels compulsive, not useful.

Appetite completely suppressed by dinnertime at week three. Some appetite suppression early on is expected. If you're still eating fewer than 1,000 calories a day at week three, the dose may need to come down.

Flat affect or mood blunting. Feeling emotionally flat, robotic, or unlike yourself — especially if it persists past the first week — is worth flagging. This isn't the same as the irritability some people feel on the comedown.

Sleep disruption past week two. A dose taken too late will disrupt sleep, but so can a dose that's simply too high. If you're going to bed at your normal time and lying awake with a racing mind, mention this at your next appointment.

How to Document a Dose Adjustment Case for Your Psychiatrist

Your psychiatrist has 20 minutes with you. They can only act on what you can show them.

The most useful thing you can do between now and your next appointment is build a structured log — not just "I think it's not working." That's not something a prescriber can act on. This is:

- Daily dose: time taken, mg
- Focus score 1–5 at peak and at the four-hour mark
- Energy score 1–5
- Side effects: specifically which ones, and at what time in the day
- One line about a representative task — "Wrote proposal, two hours, one interruption" vs "Started three things, finished nothing"

Bring 14 days of this data to your appointment. Most prescribers can read a clear pattern immediately — whether it points toward a dose increase, a dose decrease, a formulation switch (IR to XR or vice versa), or a bridge dose in the afternoon.

If you're logging in iPhone Notes or scattered across apps, the pattern won't be visible to anyone, including you.

The Right Question to Ask at Your Appointment

Most people go into dose adjustment appointments asking "can I take more?" The better question is: "Here's what I logged — what does this pattern tell you?"

That reframes the conversation. You're not asking for permission; you're presenting evidence and inviting clinical interpretation. Prescribers respond to data.

The Calibrate app structures this automatically — daily logs with focus and energy scores, side-effect tags, and a weekly PDF that surfaces the pattern clearly. The goal is to walk into your next appointment with something concrete instead of "I think maybe it's working? Sometimes?"

Dose adjustment conversations go better when both people in the room can see the same data.
