Take Cialis half an hour before sex, but enjoy its effects for up to 36 hours.
Doctors recommend taking Cialis half an hour before sex. Cialis works a bit differently than Viagra and Levitra. The biggest difference between Cialis and its competitors is that Cialis has a significantly longer half-life in the body. Whereas the half-life of Viagra, Levitra and Staxyn is about four to six hours, the half-life of Cialis is more like 18 hours. What “half-life” means is that after that time, levels of the drug start to diminish. It doesn’t mean the drug is no longer effective after that half-life time is up, but that its effects will tend to wane.
With Viagra, Levitra, and Staxyn, the effects start to wear off after four to six hours, so theoretically it’s effective for eight to 12 hours. With Cialis and its 18-hour half-life, it can continue to be effective for up to twice that long, which is 36 hours. The long half-life of Cialis is one of its biggest selling points.
In fact, you’ve probably seen it referred to in ads as the “Weekend Pill” for this reason. Cialis tends to take effect a little faster than its competitors, and most men find that it makes no difference whether or not they take Cialis with food. There’s little wonder why, although Cialis was chronologically the third big-name prescription drug approved for treating erectile dysfunction, it eventually became the top selling erectile dysfunction drug in the world.
Cialis also offers an alternative dosing regimen, where men take 2.5 mg or 5 mg of Cialis once a day for longer-term relief from erectile dysfunction. Men who have erectile dysfunction along with benign prostate enlargement can also benefit from daily Cialis therapy. When you are on a daily schedule, it’s important to take the drug at approximately the same time every day to ensure a steady level of medication in your system and maximize your ability to have sex when you want to.
