So for the ED newbies, there are 5 different ED medications. We’ve heard about Viagra, the miracle drug. But now there is always Cialis, Stendra, and Staxyn and Levitra. Sex can be fun and spontaneous! You’re caught up in the moment and the time comes to pop that little blue pill to get the little guy standing at attention but it’s taking longer than you thought. One important to note with ED medications is that it does not work its magic instantaneously. Based on brands, they have different timeframes before they work so a little forward planning is needed. Viagra and Levitra take about 30 minutes before the drug takes its effect and the other three brands Cialis, Stendra, and Staxyn take about 15 minutes. In terms of longevity, each brand is different. Viagra stays in the blood for 4 hours, Levitra for around 5, Stendra for 6, and Staxyn for 8 hours. The long laster is Cialis that has a potential to remain in the bloodstream for 36 whopping hours. But just because it stays in your system for hours does not mean your erection will last this long so don’t get freaked out.
