Atomoxetine is a prescription medication often sold under the brand name Strattera.

It treats attention deficit hyperactivity disorder (ADHD) in children, teens, and adults by increasing norepinephrine levels in the brain. Unlike stimulant ADHD drugs, atomoxetine is not a controlled substance and works differently. It can take several weeks to feel full benefit.

Typical starting doses depend on age and weight. For children and adolescents, doses are often calculated by body weight, while adults usually start with a fixed low dose and adjust upward. Your doctor will set the exact dose and may change it based on response and side effects. Do not change the dose without medical advice.

Common side effects include stomach upset, decreased appetite, sleep problems, and dry mouth. Some people notice mood changes, tiredness, or dizziness. Serious but rare risks include increased heart rate, blood pressure changes, liver injury, and suicidal thoughts in young people. Report new or worsening mood or behavior quickly, and seek immediate care for signs of liver problems like dark urine or yellowing of the skin.

Atomoxetine interacts with several medicines. Avoid strong CYP2D6 inhibitors and be cautious with drugs that affect blood pressure or heart rhythm. Combining atomoxetine with MAO inhibitors is dangerous and must be avoided. Tell your doctor about all prescriptions, over-the-counter drugs, and supplements you take.

If you miss a dose, take it as soon as you remember unless it is near the next scheduled dose. Do not double up to make up for a missed dose. For many people, atomoxetine is a daily medication taken with or without food. Consistency helps keep levels steady and improves effect.

Before starting atomoxetine, share your medical history with your provider. Mention heart problems, high blood pressure, liver disease, glaucoma, urinary retention, and any history of bipolar disorder. Also tell them about pregnancy or breastfeeding plans. Regular follow-up helps monitor benefits and side effects and may include blood pressure and heart rate checks.

Expect follow-up visits during the first few months. Your clinician will look at symptom change, side effects, and overall functioning. For young patients, schools or caregivers may help track behavior and attention. Adjustments may be needed to find the best dose.

Considering online purchases? Only use licensed pharmacies and require a valid prescription. Beware of sites that sell prescription meds without a prescription, offer extremely low prices, or hide contact details. When in doubt, ask your healthcare provider for trusted pharmacy options.

Atomoxetine helps many people who do not tolerate or cannot take stimulant ADHD medications. It is one option among several. Talk openly with your doctor about goals, concerns, and what to expect so you get the right treatment plan.

Keep a symptom log for the first three months. Note focus, sleep, appetite, mood, and any side effects. Bring the log to appointments. If you stop atomoxetine, follow your prescriber's taper instructions; sudden stops can cause return of symptoms. If you try other ADHD therapies later, share past atomoxetine results to guide future choices and dosing history.
