Strattera Dosing Considerations

Initial and target doses should be half the normal dose in patients with moderate liver impairment or one-quarter of normal doses in severe liver impairment. Your prescriber will likely discontinue Strattera if you have jaundice or severe liver injury.

How to Take Strattera

Strattera is only supplied as an oral immediate-release (IR) capsule in the US. It can be taken with or without food. Its contents can irritate the eyes, so it should not be opened, crushed, or chewed. If a patient cannot swallow it and another medication cannot be chosen, a compounding pharmacy could prepare an alternative formulation (e.g. liquid).¹

What to Do if I Miss a Dose of Strattera?

Some patients may stop using Strattera once they start feeling better. Some patients may stop using Strattera when they experience side effects from the drug. Once your body gets used to Strattera, some initial effects will be less severe or may completely disappear.

It is important to continue the medication despite these effects. Abruptly discontinuing Strattera can disrupt the stabilization of brain chemicals and lead to additional or worsening ADHD symptoms. Regular communication with healthcare professionals is recommended to address concerns, fine-tune the dosage, and ensure the best treatment outcomes.¹

Strattera’s duration of action is up to 24 hours. A missed dose could result in the return of ADHD symptoms until the next dose is taken. If enough doses are missed, it could take more time to become effective again.^{1, 6, 7, 8}

Withdrawal is very rarely observed clinically and the drug can be safely discontinued in this case.

Symptoms of withdrawal from Strattera include:¹

• Decreased heart rate
• Low blood pressure
• Inability to regulate temperature.

Can You Overdose on Strattera?
