How soon after taking Dexedrine will it show in a urine test? For example if I take it tomorrow morning at 8am, by what time will I test positive on a urine test?

I know that dexedrine reaches peak concentrations in blood after approximately 8 hours for the extended release formulation and 3 hours for immediate release formulation. Average blood* concentration levels were achieved in 12 hours.

While I'm not positive, I would imagine that if it's in your blood it's in your urine.


Dexedrine's is absorbed in stomach and excreted in urine. Higher absorption with alkaline substances. (sodium bicarbonate, etc.) increase absorption of amphetamines. Urinary alkalinizing agents (acetazolamide, some thiazides) increase the concentration of the non-ionized species of the amphetamine molecule, thereby decreasing urinary excretion.

Lower absorption with acidic foods or substances.(guanethidine, reserpine, glutamic acid HCl, ascorbic acid, fruit juices, etc.) lower absorption of amphetamines. Urinary acidifying agents (ammonium chloride, sodium acid phosphate, etc.) increase the concentration of the ionized species of the amphetamine molecule, thereby increasing urinary excretion.
