What lasts longer Generic Adderall or Adderall XR?

Adderall XR lasts longer. The XR stands for extended release and lasts around 8-12 depending on the consumer, mg, & tolerance. Generic Adderall which is actually Adderall IR (Instant Release) only lasts for a few hours (about 4 depending on the mgs) because Adderall XR is made from 2 different "beads" which one type releases automatically n the other type releases in about 4 hours so in the end Adderall xr lasts about 8 - 12 hours. When you pay for the Adderall XR you are paying for the extended release feature. SO Adderall XR lasts longer than Adderall IR.

You can't pass the test. There is no easy way to cheat it.


Why is Adderall xr better than Adderall ir?

I have always prefered IR to XR, because I believe that IR works alot longer than 3-5 hours or whatever. And XR can build you up at the beginning and make you feel as though it's worn off which leads people to take more and that's always a problem. IR I believe kicks in and doesn't wear off for 8+ hours and doesn't really make you feel bad 2 hours after taking it. Not so much it's better, it depends on what you need to accomplish. A IR is best for doing alot within 4 hours, while XR's last around 8-10hours but felt less than it's IR counterpart.


Does Adderall come in tablet form or capsule?

No. The XR stands for extended release. Extended release medications work because it takes the acid in your stomach longer to digest part of the medicine in the capsule. It isn't possible to create a tablet that does the same thing.

What dose of adderall would produce the same effects as 20 mg per day of Vyvanse?

Adderall XR comes in multiple dosage forms, and usually these are easily transcribed to IR or visa versa. However, 20 mg. of IR 3x daily does not have an equivalent XR dosage for the triple daily dose. The manufacturer offers Adderall XR 30 mg. capsules, which would mean you would take the full 60 mg dose (2 capsules) all in the morning. It would end up being equivalent to taking two 30mg dosages of IR, rather than 3x 20 mgs daily. If you feel that the 3x 20 mg. daily dosing of IR is too important, you might want to just stay on that version. You can always talk to your doc and see whats available.
