Clinical Effects of the MedicationIn clinical studies, dextroamphetamine has been shown to have a calming effect in children and teenagers with ADHD. It helps them to focus and sit still. The drug also helps them pay better attention and improve their behavior. Dextroamphetamine has also been shown to have stimulating effects for people with narcolepsy.
When and How to Take DextroamphetamineSome general considerations for when and how to take this medication include the following:
- The regular tablets should be taken by mouth, usually two or three times daily. The first dose of each day should be taken first thing in the morning. The next doses should be taken four to six hours apart.
- The extended-release capsules should be taken once a day in the morning. Because they are designed to dissolve slowly over time, the capsules should not be crushed or chewed. It is important to swallow then whole.
- You can take dextroamphetamine with or without food. If the medicine bothers your stomach, try taking it with food.
- For this drug to work properly, it must be taken as prescribed. Dextroamphetamine will not work if you stop taking it.
Dosing InformationThe dose of dextroamphetamine your healthcare provider recommends will vary, depending on a number of factors, including:
- The condition being treated (ADHD or narcolepsy)
- Your age
- Other medical conditions you may have
- Other medications you may be taking.
As is always the case, do not adjust your dose unless your healthcare provider specifically instructs you to do so.
