How long does 20mg Adderall last?
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.
What if you take 20mg adderall xr at 300pm and you take another adderall xr 20mg at 700pm will the two last 24 hours?
I just started taking 20mg adderall for adhd yesterday and have been up for over 36 hours How long is the insomnia going to last?
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.
