Atomoxetine (Strattera): Uses, Dosage, Side Effects, and Buying Tips

Atomoxetine is a non-stimulant prescription medicine used to treat ADHD in children, teens, and adults. Unlike amphetamine or methylphenidate stimulants, it works by increasing norepinephrine levels in the brain. That difference can help people who can't tolerate stimulants or who have a substance use history.

People often ask how fast it works. Expect gradual improvement: some notice focus gains in 1–2 weeks, but full benefit usually appears after 4–8 weeks. Don't stop early if you don't feel better right away — give it time and keep in touch with your prescriber.

Dosage & How to Take

Dosing depends on age and weight. For children and teens, doctors usually start low and increase based on weight. Adults often start at a fixed dose then adjust. Atomoxetine is taken by mouth once or twice daily. You can take it with food to reduce stomach upset. Follow your prescriber's instructions exactly and use the same schedule each day for best results.

Missed a dose? Take it as soon as you remember unless the next dose is close. Do not double doses to make up for a missed one. Keep regular follow-ups so the doctor can fine-tune the dose and watch for side effects.

Safety, Side Effects & Buying Tips

Common side effects include upset stomach, decreased appetite, sleep problems, and mild mood changes. A small number of children and teens may have increased suicidal thoughts. Call your doctor right away if you or your child shows worsening mood, new suicidal ideas, or sudden behavior changes.

Atomoxetine can raise blood pressure and heart rate. Your provider may check blood pressure and heart rate before and during treatment. Avoid combining it with MAO inhibitors. Also mention all medicines you take, including herbal supplements, because interactions matter.

Thinking about cost and where to buy? Atomoxetine requires a prescription. Compare prices at reputable pharmacies and use verified discount tools to lower out-of-pocket costs. Be careful with overseas or unknown online sellers that ask you to bypass a prescription — that risks counterfeit or unsafe products.

If side effects are troublesome or benefits are limited, your doctor may suggest switching to a stimulant or trying behavioral therapy. Many people do best with a mix of medication plus structured support like coaching, therapy, or school accommodations.

Questions to ask your prescriber: What dose should I expect at steady state? How long until we decide if it’s working? What side effects should prompt an immediate call? Having clear answers helps you use atomoxetine safely and get the most benefit.

Store atomoxetine at room temperature away from moisture and heat. Pregnant or breastfeeding? Tell your doctor—data are limited and they can weigh risks. Keep a written log of symptoms and side effects for the first two months to share at follow-ups. If cost is an issue, ask about generic atomoxetine, manufacturer coupons, or co-pay cards. Never share your medication and keep bottles out of reach of children. Talk to your pharmacist for savings.
