Atomoxetine 40mg is a prescription-strength non-stimulant medication. The 28-capsule pack provides a standard 4-week supply. It is commonly prescribed under brand names like Strattera.
It is indicated for the treatment of Attention-Deficit/Hyperactivity Disorder (ADHD) in adults and children aged 6 years and older. Unlike stimulant ADHD medications, atomoxetine is not a controlled substance and has no risk of abuse or physical dependence.
Atomoxetine functions as a selective norepinephrine reuptake inhibitor (NRI):
Increases Brain Signals: It raises levels of norepinephrine—a key chemical messenger in the brain that controls focus, executive function, and impulse control.
Gradual Onset: Unlike stimulants that work instantly, atomoxetine builds up gradually in your system. Initial improvements often appear within 1 to 2 weeks, while full therapeutic benefits take 4 to 6 weeks of consistent daily use.
Black Box Warning: Atomoxetine can increase the risk of suicidal thoughts or self-harm in children, teenagers, and young adults, especially during the first few weeks of starting treatment or following a dose adjustment. Caregivers should monitor for mood swings, severe anxiety, or unusual behavioral changes.
Heart Rate & Blood Pressure: Atomoxetine can elevate blood pressure and heart rate. Use with caution if you have pre-existing cardiovascular conditions.
Liver Injury: Contact a doctor immediately if you notice signs of liver dysfunction, such as yellowing of skin/eyes (jaundice), dark urine, upper right abdominal pain, or unexplained flu-like fatigue.
Dosage Strategy: 40mg is a standard initial daily starting dose for adults and adolescents weighing over 70kg (154 lbs). Your doctor may maintain this dose or increase it to 80mg daily after a minimum of 3 days based on your response.
How to Take:
Swallow the capsule whole with a full glass of water.
You can take it with or without food.
Take as a single daily dose in the morning, or split into two equal doses (morning and late afternoon).
🚨 Do NOT Open Capsules: Do not crush, chew, or open the capsule. The powder inside is a severe ocular irritant and can cause significant pain or damage if it contacts your eyes or skin.
Atomoxetine is generally well-tolerated. Common side effects can include:
Adults: Nausea, dry mouth, reduced appetite, fatigue, insomnia, urinary hesitancy, or mild dizziness.
Children: Decreased appetite, stomach ache, nausea, drowsiness, and temporary slowing of growth rate.
Store at room temperature (15°C to 30°C) away from excess heat and moisture.
Keep capsules sealed in their blister strips inside the outer box.
Keep strictly out of reach of children.
Take the missed capsule as soon as you remember that day. If it is almost time for your next scheduled dose, skip the missed dose. Never double up on capsules in a single 24-hour period.
Certain antidepressants (like fluoxetine, paroxetine, or bupropion) affect liver enzymes that break down atomoxetine. Inform your doctor about all medications you take so your dosage can be adjusted safely.
No. Atomoxetine must not be taken within 14 days of taking Monoamine Oxidase Inhibitors (MAOIs) due to the risk of severe, life-threatening reactions.
