How should I take Liquadd (dextroamphetamine)?

Take exactly as prescribed by your doctor. Do not take in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label.

Your doctor may occasionally change your dose to make sure you get the best results.

Do not take dextroamphetamine in the evening because it may cause sleep problems (insomnia).

Do not crush, chew, break, or open an extended-release capsule. Swallow it whole. Breaking or opening the pill may cause too much of the drug to be released at one time.

Measure liquid medicine with a special dose-measuring spoon or cup, not a regular table spoon. If you do not have a dose-measuring device, ask your pharmacist for one.

Your doctor will need to check your progress on a regular basis. Do not miss any scheduled appointments.

This medication can cause unusual results with certain medical tests. Tell any doctor who treats you that you are using dextroamphetamine.

You should be aware if anyone is using your medicine improperly or without a prescription. Using this medication improperly can cause death or serious side effects on the heart.

What happens if I miss a dose?

Take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose, or if it is already evening. Taking this medicine late in the day can cause sleep problems. Do not take extra medicine to make up the missed dose.

What happens if I overdose?
