It depends: What are you measuring in your definition of effective? If you would name each symptom still present, it would be easier to direct you to other alternatives. You should consult your dr, make a list of symptoms that you would like to see disappear, and he will help you.

Delivery form: Both a amphetamine (amp). Adderall is a blend of d-amp (50%) and d, l-amp (50%). Vyvanse (lisdexamfetamine) is called a prodrug: it is d-amp linked to an amino acid. It is inactive till it gets in the body, where an enzyme cleaves the molecule, releasing d-amp. That means a very different release pattern, and it is the longest acting oral stimulant. Some like one, others the other. Both can be effective.

Could you give me more information about Adderall versus vyvanse (lisdexamfetamine)?

Sure.: Adderall xr has a two-hit delivery system, one kicking in 20-30 minutes after taking it and then again 3 1/2 to 4 hours later. Vyvanse (lisdexamfetamine) is a prodrug that is inactive till it gets into the body and is broken down into lysine and amphetamine. That means effects start up much more slowly (1-2 hours) and taper off much more gradually. Side effects and benefits are about the same.

Evaluation: You would need to see a physician or specifically a psychiatrist. These medications are prescribed for add/ adhd. The provider would determine which medication would be the most appropriate for you. Take care.
