Your doctor will probably decrease your dose gradually and monitor you carefully during this time. You may develop depression and extreme tiredness. if you suddenly stop taking amphetamine after overusing it.

Amphetamine (Adzenys ER, Adzenys XR, Dyanavel XR, Evekeo, Evekeo ODT, others) is used as part of a treatment program to control symptoms of attention deficit hyperactivity disorder (ADHD; more difficulty focusing, controlling actions, and remaining still or quiet than other people who are the same age) in adults and children. Amphetamine (Evekeo, others) is also used to treat narcolepsy (a sleep disorder that causes excessive daytime sleepiness and sudden attacks of sleep). Amphetamine (Evekeo, others) is also used for a limited period of time (a few weeks) along with a reduced calorie diet and an exercise plan for weight loss in obese people unable to lose weight. Amphetamine is in a class of medications called central nervous system stimulants. It works by changing the amounts of certain natural substances in the brain.

Amphetamine comes as an immediate-release tablet (Evekeo), an orally disintegrating tablet (tablet that dissolves quickly in the mouth; Evekeo ODT), an extended-release (long-acting) orally disintegrating tablet (Adzenys XR), and as an extended-release (long-acting) suspension (Adzenys ER, Dyanavel XR) to take by mouth. The extended-release suspension is usually taken once daily in the morning with or without food. The orally disintegrating tablet is usually taken once daily in the morning with or without food or liquid. The extended-release orally disintegrating tablet is usually taken once daily in the morning with or without food. For treatment of ADHD or narcolepsy, the immediate-release tablet is usually taken with or without food 1 to 3 times daily, 4 to 6 hours apart, with the first dose in the morning. For weight loss, the immediate-release tablet is usually taken 30 to 60 minutes before meals. Amphetamine should not be taken in the late afternoon or evening because it may cause difficulty falling asleep or staying asleep. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take amphetamine exactly as directed.

Swallow the extended-release tablets whole, do not chew or crush them.

Do not try to push the orally disintegrating tablet (Evekeo ODT) or the extended-release orally disintegrating tablet (Adzenys XR) through the blister pack foil. Instead, use dry hands to peel back the foil packaging. Immediately take out the tablet and place it in your mouth. The tablet will quickly dissolve and can be swallowed with saliva. No water is needed to swallow the tablet.

Shake the extended-release suspension (Adzenys ER, Dyanavel XR) well before each use to mix the medication evenly.

Do not add the extended-release suspension (Adzenys ER) to food or mix it with other liquids.

It is important to use an oral syringe (measuring device) to accurately measure and take your dose of the extended-release suspension. Ask your pharmacist for a device if it was not provided. Wash the oral syringe thoroughly after each use.

If you or your child are taking amphetamine for ADHD, your doctor will probably start you on a low dose of amphetamine and increase your dose gradually, every 4 to 7 days, depending on the medication. Your doctor may tell you to stop taking amphetamine from time to time to see if the medication is still needed. Follow these directions carefully.

If you are taking amphetamine for narcolepsy, your doctor will probably start you on a low dose of amphetamine and increase your dose gradually, not more often than once every week. Follow these directions carefully.

The medication in each product is absorbed differently by the body, so one amphetamine product cannot be substituted for another product. If you are switching from one product to another, your doctor will prescribe a dose that is best for you.

This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
