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.
For example, nitrous oxide and other sedative gases are inhaled, but ketamine and Valium are injected into an IV line. How long the procedural sedation lasts depends on the drugs administered -- it may be as few as five or 10 minutes or as long as an hour. Recovery is speedy, and you won't usually have the side effects associated with general anesthesia, such as vomiting, nausea or dizziness (although they can still occur).
