General Information
Atomoxetine is a medication prescribed for the treatment of attention deficit hyperactivity disorder (ADHD) - a learning and behavioural disability characterized by a very short attention span, impulsiveness, and hyperactivity. It has been shown to improve behaviour at school, self esteem and family function. The drug can be safely used in children older than 6, adolescents and adults.
Atomoxetine is unique when compared to other medication for ADHD, because it is the first medication for this condition that is not a controlled substance or stimulant.
For this medication to be effective it has to be taken regularly, even if you do not notice an immediate effect. The full effect of atomoxetine will only be experienced after 3-4 weeks of use. It is recommended that atomoxetine should not be the only treatment for a patient with ADHD - It should be part of a complete treatment plan that includes psychological, educational and social measures designed to further assist in improving the condition.
Atomoxetine should only be taken as prescribed. Higher doses than those recommended does not provide any additional benefit.
There is a possibility that atomoxetine may slow the average growth in children, but it is unclear if weight and height of these kids are indeed affected when they reach adulthood. The manufacturer of the medication does however advise that treatment should be interrupted if it becomes apparent that weight gain and growth is not at the expected level.
If you are currently taking an antidepressant that is classified as a monoamine oxidase inhibitor (MAOI), you should under no circumstance start treatment with atomoxetine within 2 weeks of stopping this drug.
At the start of treatment with this medication you may feel dizzy when suddenly getting up - Be aware of this and remember to get up slowly during the first few days of treatment
How does Atomoxetine work?
Atomoxetine works by increasing levels of the neurotransmitter noradrenaline in the brain.
