Before delving into how long it takes before you can expect Cialis to start improving your sexual performance, it is worth clarifying some aspects of how the drug works. Cialis is not a cure for low libido, nor will it create an erection if there is no natural trigger. So for the drug to take effect, the user must receive a certain amount of sexual stimulation. When it comes to arousal, it remains largely contingent on one's subjective perception and response to sexual stimulation. When the factors that naturally lead to arousal work in the right direction, Cialis will simply help improve suboptimal erectile function. More specifically, what this ED drug does is facilitate an erection by dilating blood vessels and increasing blood flow to the penis. In the absence of sexual stimulation, the drug’s effects will not be noticed. With this in mind, it becomes easier to manage when to take the drug.

How soon is the onset?

bored waitingOn average, Cialis takes about 30 to 45 minutes to kick in. It may take only 15 minutes or up to two hours depending on the individual's age, physiology, and psychological susceptibility. Its effects generally become more pronounced after a few hours have gone by, and will last for quite a while. Also, keep in mind that taking the pill after a hearty meal, especially a fatty one, can delay the onset of the drug.

How long does it last?

One of Cialis’ greatest advantages relative to other ED drugs is that its invigorating effect lasts much longer. It can stay in the system for up to two days. So Cialis is often preferred to other medications that work on the basis of a similar principle because the user can take advantage of the drug’s effect at any time during a period of almost two days after consumption, which gives users greater freedom and allows for more spontaneity. On average, Cialis lasts up to 36 hours, although the specific duration may vary from one individual to another.
