Prescribing information revised for ADHD drug: can raise heart rate, blood pressure

TORONTO - Health Canada and the drug company Eli Lilly Canada are notifying doctors and patients of risks associated with an ADHD medication used by children and adults.

They say atomoxetine, sold as Strattera, can increase heart rate and blood pressure.

Prescribing information has recently been revised to include the warning to those using the drug to treat attention deficit hyperactivity disorder.

The advisory released Monday says atomoxetine should not be used in patients with severe heart-related disorders, and it should be used with caution by people whose underlying medical conditions could be worsened by increases in blood pressure or heart rate.

ADHD patients or their caregivers should tell the doctor if there are any heart problems, heart defects, high blood pressure or a family history of these problems.

Patients should not stop treatment or modify the dosage without discussing their condition with their health-care provider.

The doctor should also be notified of signs of heart problems such as chest pain, irregular heart rate, palpitations, shortness of breath, dizziness or fainting while taking the drug.
