Atomoxetine, sold under the brand name Strattera among others, is a medication used to treat attention deficit hyperactivity disorder(ADHD).[6] Use is only recommended in those who are at least six years old.[6] It is taken by mouth.[6]
Common side effects include abdominal pain, loss of appetite, nausea, feeling tired, and dizziness.[6] Serious side effects may include angioedema, liver problems, stroke, psychosis, heart problems, suicide, and aggression.[6][7] Safety in pregnancy and breastfeeding is not clear.[8] Atomoxetine is a norepinephrine reuptake inhibitor which is how it is believed to work.[6]
Atomoxetine was approved for medical use in the United States in 2002.[6] A month's supply in the United Kingdom costs the NHS about 53 £ as of 2019.[7] In the United States, the wholesale cost of this amount is about 77 USD.[9] In 2016, it was the 245th most prescribed medication in the United States, with more than 2 million prescriptions.[10]
Medical uses
Attention deficit hyperactivity disorder
Atomoxetine is approved for use in children, adolescents, and adults.[11] However, its efficacy has not been studied in children under six years old.[2] Its primary advantage over the standard stimulant treatments for ADHD is that it has little known abuse potential.[2] While it has been shown to significantly reduce inattentive and hyperactive symptoms, the responses were lower than the response to stimulants. Additionally, 40% of participants who were treated with atomoxetine experienced residual ADHD symptoms.[12]
The initial therapeutic effects of atomoxetine usually take 2–4 weeks to become apparent.[1]A further 2–4 weeks may be required for the full therapeutic effects to be seen.[13] Its efficacy may be less than that of stimulant medications.[14]
Unlike α2 adrenoceptor agonists such as guanfacine and clonidine, atomoxetine's use can be abruptly stopped without significant discontinuation effects being seen.[2]
