Atomoxetine (Strattera) belongs to the selective norepinephrine reuptake inhibitors (SNRIs) category. It solely treats ADHD (attention deficit hyperactivity disorder) in children (6 years and older), teenagers, and adults, while Adderall belongs to ‘stimulants’ and is mostly used to treat ADHD, it also treats Narcolepsy (daytime sleep disorder), stimulates psychological and cognitive functions as well. Since Adderall is a stimulant, thus it may be abused. However, as Atomoxetine (Strattera) is not a stimulant, the probability for it to be abused is pretty low. Here is a comparison of Atomoxetine vs Adderall, including Indications, Active Ingredients, Dosage and Administration, Warnings, Adverse Drug Reactions, Effectiveness, Precautions, and Long-term Effects (if any).

 

Atomoxetine	Adderall
Indications ADHD	Indications ADHD Narcolepsy
Active Ingredients Atomoxetine Hydrochloride	Active Ingredients Dextroamphetamine Saccharate Amphetamine Aspartate Monohydrate Dextroamphetamine Sulfate Amphetamine Sulfate USP
Dosage and Administration Dosage and Administration (For Children & Adolescents up to 70 kg) Start: 0.5-40mg/day, Target: 1.2mg/kg/day, Max: 1.4mg/kg/day (For Children/Adolescents over 70 kg and adults) Start: 40mg/day, Target: 80mg daily dose Max: 100mg daily dose	Dosage and Administration for ADHD Dosage and Administration (For children 3 – 5 years) Start: 2.5 mg daily (may be increased with one-week intervals until required results are obtained. (For children aged 6 and older individuals) Start: 5mg once or twice daily which may be increased by 5 mg with weekly intervals
Warnings Suicidal Thoughts Severe Liver Injury Allergic Events Bipolar disorder Concomitant Use of Potent CYP2D6 Inhibitors or use in patients who are known to be CYP2D6 PMs (premenstrual syndrome)	Warnings Serious Cardiovascular Events, especially in people with Bipolar disorder Long-Term Suppression of Growth Seizures Serotonin Syndrome Visual Disturbance
Adverse Drug Reactions (Seen in trials) In Children and Adolescents Nausea vomiting Fatigue Decreased appetite Abdominal pain Somnolence In Adults Constipation Dry mouth Nausea Fatigue Decreased appetite Insomnia Erectile dysfunction Urinary hesitation Urinary retention Dysuria Dysmenorrhea Hot flush	Adverse Drug Reactions Cardiovascular Central Nervous System Eye Disorders Gastrointestinal issues Allergies Endocrine Skin Musculoskeletal
Effectiveness Generally considered effective for ADHD, but may take longer to work than stimulants.	Effectiveness Generally considered effective for ADHD, and can have more immediate effects.
Precautions Use caution in patients with glaucoma, high blood pressure, or a history of seizures. Monitor for growth in children	Precautions Use caution in patients with heart problems, anxiety, or a history of substance abuse. Monitor for changes in mood or behavior.
Long-term Effects Potential for growth suppression in children. Long-term effects are not well-established	Long-term Effects Potential for dependence and tolerance. Long-term effects on heart health are being studied

To be adjusted after drug reactions:

According to Pubmed, “The CYP2D6 enzyme is involved in the metabolism of atomoxetine”, similarly Adderall is metabolized in the liver and the same enzyme is responsible for its breakdown, thus, poor metabolizers are at higher risks of side effects and the FDA suggests that the dosages should be adjusted accordingly. Not only Atomoxetine and Adderall, but multiple other medications, especially mental health medications, tend to affect individuals differently based on their genetic makeup.

Pharmacogenomics testing, commonly known as PGx testing gives you insights into your genome (set of all DNA). An easy at-home PGx test by RPh Labs, requiring just a saliva cheek swab can show how you may respond to 250+ medications.

Important:

The FDA label for Atomoxetine includes warnings about the risk of liver injury, including increases in liver enzymes and cases of hepatitis. Moreover, while Adderall and Atomoxetine both carry cardiovascular risks, Adderall specifically states in its boxed warning section about the risk of heart attacks and even sudden deaths.

According to Verywellhealth on Atomoxetine vs Adderall, “Adderall is generally more effective than Strattera for treating ADHD symptoms. However, it may not be suitable for everyone, particularly children and adolescents or those who may be unable to tolerate side effects.”

Conclusion:

While Atomoxetine and Adderall both are used to treat ADHD, Adderall, being a stimulant, is usually considered a treatment for ADHD. In contrast to Adderall, Atomoxetine (Strattera) which is a selective norepinephrine reuptake inhibitor (SNRI), being a non-stimulant has less probability of abuse. Therefore, it’s best to leave it to your doctor to decide between Atomoxetine vs Adderall according to your ADHD condition and other health factors. Rest, as the CYP2D6 enzyme is involved in the metabolism of both of these drugs, taking a PGx test may help your doctor prescribe you the best drug and dosage as per your genome. Unsure how to take a PGx test? Here is how it works.
