How much adderall should you take with 100mg of seroquel?

It totally depends on what you are taking it for. 100 mg of seroquel will knock you out if you aren't extremely used to it. The doses of both seroquel and adderall change based on how much you have done in the past, plus what your underlying disorder is. If this is for medical purposes, consult your doctor. If this is for recreational purposes, don't take any more adderall than you would take w/o the seroquel... the seroquel will obviously mitigate some of the effects (as adderall causes more dopamine to be released and seroquel, among other things, antagonizes the d2 receptor).

I currently take 25 mg of seroquel at night and 15 mg of adderall xr in the morning, and the combination is fantastic. But take that with a grain of salt, b/c everyone's physiology is different. In that respect, this question is kind of like "how many lines of coke should you snort with 6 beers?" It can't be answered without a lot more information.

Seroquel mainly antagonizes the d2 receptor of the brain. ADHD which adderall treats mainly has threaputic affects through the d4 receptor which seroquel has minimal affinity. Your seroquel shouldn't affect the effects of adderall so your normal dose should do fine maybe a 5 mg increase might help if you're taking a particularly high dose of seroquel
