Yes, you can take your Qelbree dose at night or during the day. Since you’ll take Qelbree once per day, it’s helpful to take it around the same time of day. This helps keep a stable level of the drug in your body so it can work well. To learn more, see the “How to take Qelbree” section below.

How long does a dose of Qelbree last?
Typically, an effective dose of Qelbree lasts about 7 hours. The drug is taken once per day and is an extended-release oral capsule. “Extended release” means the active drug (viloxazine) releases slowly into your body over time. So, Qelbree is typically effective in your system until the time of your next daily dose.
For more information about how long Qelbree lasts, talk with your doctor or pharmacist.
The Qelbree dosage your doctor prescribes will depend on your age. The dosage in children ages 6 to 11 years is typically lower than the dosage in older children and adults. For details, refer to the “Qelbree dosage” section above.
Other medical conditions you have can also affect your Qelbree dosage.
If you have kidney problems, your doctor may prescribe a lower dosage of Qelbree. Kidney problems slow down the removal of Qelbree from your body, which increases your risk of side effects from the drug.* So your doctor may prescribe a lower starting dosage. They may also adjust it more slowly to reach the drug’s desired effect.

ACCESSIBLE DRUG LABELS AND CONTAINERS
Some pharmacies offer labels with large print, braille, or a code you scan with a smartphone to convert text to speech. If your local pharmacy doesn’t have these options, your doctor or pharmacist might be able to recommend a pharmacy that does.
If you’re having trouble opening medication bottles, ask your pharmacist about putting Qelbree in an easy-open container. They also may recommend tools that can make it easier to open bottles.
If you miss a dose of Qelbree, take it as soon as you remember. However, if it’s almost time for your next dose, skip the missed dose. Then, take your next dose when you typically would. Do not take two doses of Qelbree to make up for the missed one.
