Adderall XR capsules are available in 5 mg, 10 mg, 15 mg, 20 mg, 25 mg and 30 mg versions. As with other stimulants, the usual philosophy is to start with a low dosage that is increased gradually and in weekly intervals as needed. Never increase your dose of Adderall without your healthcare provider's OK.
Given that there are some concerns that the drug may restrict growth in children, those taking the medication may be periodically taken off of it under the guidance of a healthcare provider to see if it's still needed over time. In general, the dosage of Adderall is about half that of Ritalin methylphenidate. For those switching from the regular version of Adderall to the extended-release version, the total daily dosage is typically the same. For example, if a child was taking 10 mg of Adderall twice a day 20 mg altogether , they would now take one mg Adderall XR capsule each morning.
For both ADHD and narcolepsy, the first dose is typically taken first thing in the morning with one or two subsequent doses taken at intervals of four to six hours apart. Late evening doses should be avoided to prevent insomnia. If you miss a morning dose, take it as soon as you remember. But if it's within a few hours of your next dose, skip it and just take the next one as scheduled. If you miss a mid-day dose, skip that one and instead take your next dose the following morning since taking one too late in the day can interfere with sleep.
Adderall XR is taken once daily in the morning. If you miss a dose of the extended-release capsule, do not take it later that day. Instead, take your next dose at the regular time the next morning. Adderall can be taken with or without food and should be stored at room temperature ideally 68 to 77 degrees F. As with all medications, keep it out of the reach of children.
If you or your child take too much Adderall, call your healthcare provider or poison control center right away, or get emergency treatment. Although generally well tolerated, Adderall comes with the risk of side effects, especially when first taking the medication.
