Important: How To Use This Information

This is a summary and does NOT have all possible information about this product. This information does not assure that this product is safe, effective, or appropriate for you. This information is not individual medical advice and does not substitute for the advice of your health care professional. Always ask your health care professional for complete information about this product and your specific health needs.

Warning

A small number of people who take viloxazine for attention-deficit hyperactivity disorder (ADHD) may experience worsening of their condition, other mental/mood symptoms, or suicidal thoughts/attempts. It is very important to talk with the doctor about the risks and benefits of this medication.

Tell the doctor right away if you notice worsening of your condition/other psychiatric conditions, unusual behavior changes (including possible suicidal thoughts/attempts), or other mental/mood changes (including new/worsening anxiety, panic attacks, depression, trouble sleeping, irritability, hostile/angry feelings, hallucinations, delusions, impulsive actions, severe restlessness, very rapid speech). Be especially watchful for these symptoms when you first start this medication or when the dose is changed.

Uses

Viloxazine is used by children to treat attention-deficit hyperactivity disorder (ADHD) as part of a total treatment plan, including psychological, social, and other treatments. It may help to increase the ability to pay attention, concentrate, stay focused, and stop fidgeting. It is thought to work by restoring the balance of certain natural substances (neurotransmitters) in the brain.

How To Use

Read the Medication Guide provided by your pharmacist before you start using viloxazine and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

Take this medication with or without food as directed by your doctor, usually once daily. Swallow the capsules whole. Do not crush, chew, or cut the capsules. Doing so can release all of the drug at once, increasing the risk of side effects.

If you have trouble swallowing the capsules whole, you may open the capsule and sprinkle the contents onto a spoonful of applesauce. Swallow all of the mixture without chewing. The mixture should be used within 2 hours of mixing. Do not save the mixture for future use.

The dosage is based on your age, medical condition, and response to treatment.

Use this medication regularly to get the most benefit from it. To help you remember, take it at the same time each day.

Do not increase your dose or use this drug more often or for longer than prescribed. Your condition will not improve any faster, and your risk of side effects will increase.

Tell your doctor if your condition does not get better or if it gets worse.
