If it is the short acting dose it lasts around 4 hours. If it is the "XR" or extended release form it can last anywhere from 6-12 hours. Both would be out of a person's system in 24 hours.

taking 20mg of adderall will last you four to six hours if you are taking the capsules. dumping the pill strait onto your tongue makes it work faster, but not as long. hope this helped a little...

It seems to range from person to person, but from my experience, it usually takes about 30 minutes to an hour to feel the effects of adderall begin.

First, it is Adderall XR. And yes 2 10mg of immediate relase Adderall is equivalent to Adderall XR 20mg. The Adderall XR is time released so if you are taking Adderall XR 20mg, 10mg will be released immediately and 10mg will be released 4 hours later.

You may feel after effects for 24 hours, but the major effect will be over 8 hours or so after the second dose. Mabe slightly longer since they're XR

how long does 15mg Adderral last

User Avatar

it depends on if it is an extended release capsule or just a generic tablet. 40 mg total is a lot of adderall to be taking at once and it will last for about 8-12 hours.

I have been on 20mg of Adderall XR 2x a day plus 60mg of Cymbalta for a couple years now.

Yes, and it is stronger. Some people may not even feel the 10mg's effect because it is so low.

it depends on how many tablets you need for one months supply and if it's Adderall XR or not.

Do not do this. The side affects of an overdose can be sudden death.

That depends on your body weight and if get alot of exercise. But the norm is up to 28 days

The impact of such medication should be discussed with the person who prescribed, in that way they can see and define anything unusual

Adderall contains amphetamines which are stimulants and hydrocodone are opiates which are considered depressants. If your using it medically then there's no problems, if you want to get high though I'd be careful. I personally used 20mg of snorted adderall and ate 20mg of hydrocodone and had a very nice time. So yes to answer the question it can effect hydrocodone.

Answer Adderall XR should be effective 10-12 hours.

A regular 5 mg adderall will last about 4 hours at the most.

adderall lasts for up to twelve hours then it starts to wear off.
