Adderall Dosage Guide/Chart
If you’re searching for an Adderall dosage chart, the following infographic provides a general overview of what an Adderall dosage might look like.
What Dosage Does Adderall Come In?
Adderall XR dosage begins at 5 mg. Then there are 10 mg, 15 mg, 20 mg, 25 mg, and 30 mg dosages.
The Adderall IR dosage options start at 5 mg and include 7.5 mg, 10 mg, 12.5 mg, 15 mg, 20 mg, and 30 mg. There is more flexibility in immediate-release dosages, allowing doctors to start patients out on a minimal dose and increase it incrementally.
Recommended Dosage for Adults
Doctors will usually start an Adderall dosage at the smallest amount that may potentially work and then gradually increase it. For ADHD, the immediate-release dosage for adults is between 5 mg to 40 mg a day. The dosage is divided throughout the day.
In regards to ADHD, doses of more than 40 mg a day are rarely more effective than lower amounts. For narcolepsy treatment, doctors may begin with 5 mg a day and then go up to 60 mg a day, with dosages given every four to six hours.
With Adderall XR, one dose is taken daily instead of in divided doses. A doctor may still recommend that the extended-release dosage not exceed 40 mg a day.
How Long Does Adderall & Adderall XR Work?
Adderall immediate-release (IR) starts working within 15 to 30 minutes and lasts for about 4 to 6 hours. Adderall extended-release (XR) can take about 30 to 60 minutes to start working, and it lasts for around 10 to 12 hours. Both IR and XR can lead to a crash as someone comes down from the effects of the drug, but XR tends to have less noticeable effects.
Avoiding an Adderall Dosage High
Trying to abuse Adderall to get high is very dangerous. At higher doses, it can be associated with sudden death. Determining how much Adderall would get someone high is almost impossible, as different people will have different reactions. Some people get high from Adderall by crushing and snorting it or dissolving and injecting it. These methods make the risks even greater.
It’s possible to experience a fatal dose when using Adderall to get high, so this should be avoided. People should never take Adderall without a prescription from their doctor. If they do have a prescription, it should only be used as directed.
