There are subtle differences in how long the drug works and how quickly it works. Levitra works a little longer than Viagra. They both take effect in about 30 minutes. With Levitra, the effects last for about 5 hours. With Viagra, the effects last approximately 4 hours. Cialis works a bit faster (within about 15 minutes), and the effects last much longer -- up to 36 hours in some cases. Stendra can start working in as little as 15 minutes and last up to 6 hours.
How long will Vyvanse's effect last? Depends how much you took, if you took 70mg probably 12 hours or so but if you took a real high dose like 140mg probably 18 hours maybe a little more. A little more kick to it than 5 hour energy.Lisdexamfetamine is a prodrug of dextroamphetamine.Amphetamine is a scheduled drug and if you do not have a prescription it is against the law to obtain or use.
