Strattera: the ADHD med that isn't a stimulant
Atomoxetine (Strattera, Axepta) is a non-stimulant ADHD medicine that works quietly in the background. How long it takes, doses, side effects and what people on it say.
Atomoxetine is the ADHD medicine for people who would rather not take a stimulant, or can’t. It doesn’t give you a rush or a crash, and it isn’t a controlled drug. Instead it works quietly in the background, building up over a few weeks until focus and calm feel more like your normal. Strattera is the original brand; in India it is sold as Axepta, and generic atomoxetine is widely available.
Key points
- Licensed for ADHD in adults and children from age 6 in the US, and for ADHD in the UK.
- Give it time. Most people need a few weeks before they can judge it. The studies behind its approval ran 6 to 10 weeks.
- No highs, no crashes, all-day cover. It isn’t a stimulant and showed no “high” in abuse testing.
- Side effects are usually mild: an upset stomach, dry mouth, less appetite or poorer sleep at first. Taking it after food helps many people.
Who it is for
Atomoxetine is a good fit if stimulants gave you side effects, worried your doctor (for example because of anxiety, a heart condition or past substance use), or are simply hard to get where you live. Some people also take it alongside a stimulant.
| Where | What the license says |
|---|---|
| United States | ADHD in adults and children 6 and over. Not a controlled substance. |
| United Kingdom | Licensed for ADHD. NICE, which writes England’s guidelines, suggests it when the stimulants methylphenidate and lisdexamfetamine didn’t suit you or didn’t work after 6-week trials. For adults whose symptoms didn’t start in childhood, it counts as off-label. |
| Under 6 | Not established in the US; NICE lists age 5 as off-label. |
Other uses, such as binge eating or sleep apnea, are off-label everywhere. They’re covered further down.
How it works
Atomoxetine keeps more norepinephrine, a brain chemical tied to attention and alertness, active between nerve cells. It doesn’t push dopamine the way stimulants do, which is why it has no “kick” and no comedown.
Because it builds up, the change can be subtle. People often notice they’re calmer, less scattered, or getting through their to-do list before they notice anything “working”. Its half-life is about 5 hours in most people. About 7 in 100 White people, and 2 in 100 Asian and Black people, process it slowly (they lack an enzyme called CYP2D6); for them it lasts about 22 hours and levels run about ten times higher, so doctors raise the dose more slowly.
How much people take
Your prescriber sets the dose. These are the US label numbers:
| Start | Increase after | Usual dose | Maximum | |
|---|---|---|---|---|
| Adults and children over 70 kg | 40 mg a day | at least 3 days | 80 mg a day | 100 mg a day |
| Children under 70 kg | 0.5 mg per kg a day | at least 3 days | 1.2 mg per kg a day | 1.4 mg per kg a day or 100 mg, whichever is lower |
- When: once in the morning, or split into morning and late afternoon.
- Food: with or without food. Swallow capsules whole; don’t open them.
- Strengths: capsules of 10, 18, 25, 40, 60, 80 and 100 mg. Axepta comes as tablets.
- Going higher: only if 80 mg isn’t enough after another 2 to 4 weeks.
- Liver problems: half the dose for moderate problems, a quarter for severe.
- Missed a dose? Take it when you remember, but never more than your daily total in 24 hours.
- Stopping: no taper is needed and there’s no withdrawal, but ADHD symptoms come back, so plan it with your prescriber.
Side effects
The good news: the common ones aren’t dangerous, and on Reddit many people say they ease after the first weeks. In adult trials with 1,697 people on atomoxetine:
| Side effect | Atomoxetine | Placebo |
|---|---|---|
| Nausea | 26% | 6% |
| Dry mouth | 20% | 5% |
| Less appetite | 16% | 3% |
| Trouble sleeping | 15% | 8% |
| Tiredness | 10% | 6% |
| Erection problems (men) | 8% | 1% |
| Constipation | 8% | 3% |
| Dizziness | 8% | 3% |
| Slow or difficult peeing | 6% | 1% |
| Delayed ejaculation (men) | 4% | 1% |
About 11 in 100 adults stopped because of side effects (3 in 100 on placebo). Sexual side effects are probably under-reported in trials, so if you notice them, say so: your prescriber may adjust the dose or timing. In children the most typical effects were nausea, vomiting, tiredness, less appetite, stomach ache and sleepiness, and doctors keep an eye on growth.
The rare but serious ones
- Suicidal thoughts in children and teens. In short trials, 4 in 1,000 children on atomoxetine had them, compared with none on placebo, all in the first month. Adults showed no increase.
- Liver injury. Rare, usually within the first four months. If it happens, atomoxetine is stopped for good.
- Heart rate and blood pressure rise a little on average, and more in about 5 to 10 in 100 people, so your prescriber checks them. It isn’t for people with serious heart problems.
- Mood swings, mania or aggression can appear, which is why doctors ask about bipolar disorder first.
- Trouble passing urine (1.7% of adults) and, very rarely, a painful long-lasting erection.
- Don’t take it with narrow-angle glaucoma, a pheochromocytoma (an adrenal tumor), severe heart or blood vessel disease, or within 14 days of an MAOI antidepressant.
Medicines that don’t mix
- Paroxetine and fluoxetine (two common antidepressants) raise atomoxetine levels six- to eightfold. Your prescriber can still combine them, with slower dose steps.
- MAOI antidepressants, and the antibiotic linezolid: never together, and 14 days apart either way.
- Blood pressure medicines, and albuterol (salbutamol) tablets or injections: more blood pressure and heart rate checks.
- Alcohol: in a study, atomoxetine didn’t make people feel more drunk.
Ask your pharmacist to check anything else you take.
Does it work?
Yes, for many adults, though it is gentler than the stimulants.
- A 2016 review of 13 trials in 1,824 adults found a moderate benefit, strongest for inattention.
- A large 2018 comparison of ADHD medicines in The Lancet Psychiatry found the same moderate effect in adults. Amphetamines had the biggest effect.
- A 2025 review of 113 adult trials found that stimulants and atomoxetine were the only treatments with solid evidence of easing ADHD symptoms.
The trade-off: in those trials more people stopped atomoxetine than placebo, mostly because of side effects. On Reddit, people who stay on it often describe a calmer, steadier day rather than a dramatic change.
Other things it has been tested for
None of these is licensed. They show where research is heading, not advice.
| Use | Study | What happened |
|---|---|---|
| Binge eating | 10-week trial, 40 adults | Fewer binges, less hunger and some weight loss compared with placebo |
| Sleep apnea (with aroxybutynin, as “AD109”) | 26-week phase 3 trial, 646 adults who couldn’t or wouldn’t use CPAP | 4 fewer breathing pauses an hour than placebo; still an investigational product |
| Sleep apnea (with oxybutynin) | 1-month trial, 58 adults | A small drop in breathing pauses, too small on average to matter, the authors said |
| Dizziness from low blood pressure on standing | Single doses in 65 patients (2014); 4 weeks in 37 patients (2024) | Single doses raised standing blood pressure more than midodrine, but a month of treatment didn’t ease symptoms more than placebo |
| Bedwetting in children | Trial in 87 children | 1.5 more dry nights a week, against 0.6 on placebo |
Indian brand: Axepta
Axepta, made by Intas Pharmaceuticals, is the Indian brand of atomoxetine. It contains the same medicine as Strattera, comes as pale yellow tablets (10, 18, 25, 40 and 60 mg). Compare it with the other Indian brands on Indian brands.
What people say
From 61 Reddit threads about Strattera or atomoxetine, 2011 to 2026. These are personal stories, not evidence; the numbers count threads, not people.
- It’s a slow burn (15 threads). The most common advice is to give it a month. “Strattera generally takes about a month to really do much” (r/ADHD).
- You notice it looking back (3 threads). “It’s definitely more challenging to know that it’s working as it doesn’t “kick in” like amphetamines” (r/ADHD).
- Appetite, both ways (25 threads). Some people eat much less; others notice nothing. “I’ve been on Strattera 80mg for about 6 months. I have never felt nauseous on it and my appetite hasn’t changed at all” (r/ADHD).
- Eat first (9 threads). “Eat before you take a pill. Seriously, it makes it so much better” (r/ADHD).
- Sexual side effects in men (11 threads). “Strattera worked great, no libido issue, but I did get ED and I think it’s called delayed urination side effect” (r/ADHD). Worth raising with your prescriber rather than putting up with.
- Head rushes at first (4 threads). “Every time I got up without being painfully slow I’d get a rush of blood to my head and my vision would get spotty” (r/ADHD). Stand up slowly and mention it to your prescriber.
- Tired? Some switch to evenings (9 threads). “I take it at night because it was making me really groggy during the day” (r/qelbree). Change timing only with your prescriber’s OK.
- A good partner for a stimulant (5 threads). “I always felt like vyvanse was doing just half the job” (r/ADHD). Combining the two is your prescriber’s call.
- Mood dips for a few (11 threads). If you feel low or flat, tell your prescriber; there are other options.
Where to buy

Questions people ask
Is atomoxetine a stimulant?
No. It doesn’t give a buzz, showed no stimulant effect in abuse testing, and isn’t a controlled substance in the US. That’s why it’s often the first choice when stimulants don’t suit you or are hard to get.
How long does Strattera take to work?
Usually a few weeks. Approval studies lasted 6 to 10 weeks, and doctors wait 2 to 4 weeks at the usual dose before going higher. Some people feel calmer sooner.
Can I take atomoxetine with a stimulant?
Some prescribers combine them, though it isn’t an approved regimen. In a study, adding atomoxetine to methylphenidate didn’t raise heart rate or blood pressure beyond methylphenidate alone.
Will Strattera make me lose weight?
It might dull your appetite: about 1 adult in 6 had less appetite in trials, and 2 in 100 lost weight as a side effect. Some people on Reddit report big losses, others none. It isn’t a weight-loss medicine.
Is Axepta the same as Strattera?
Same medicine, atomoxetine, from an Indian maker (Intas). Axepta comes as tablets rather than capsules. See Indian brands.
Do I need to taper off Strattera?
No taper is needed and there’s no withdrawal syndrome. Your ADHD symptoms will come back, though, so plan the stop with your prescriber.
