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.
This will determine how fast it takes effect. An injection or IV takes effect in 5 to 15 minutes with maximum effect in 15 to 60 minutes and has effects lasting for about 2 hours but with a range of 1 to 6 hours. The amnesia effect lasts for 20 minutes to an hour depending on how it is administered. Taking the syrup, effects in children are seen in 10 to 20 minutes. Midazolam is broken down in the liver to both active and inactive metabolites, so it has two phases of elimination from the body.
