How Long Does Cialis Last, and Why Might That Be a Problem?

The effects — both good and bad — of Cialis can last for up to 36 hours. If you need erectile dysfunction relief for a single sexual encounter, you’re probably best advised to go with an ED drug with a significantly shorter half-life. 

Unique among currently available erectile dysfunction drugs, Cialis has a half-life of 17.5 hours, sharply higher than those of its competitors. By contrast, Viagra, one of its biggest competitors, has a half-life of only three to four hours.

Half-life refers to the time it takes for 50 percent of a drug’s active ingredient to be cleared from the body. Pop a Cialis tablet, and you’ll still have half of its active ingredient — tadalafil — in your bloodstream 17.5 hours later.

Significance of Half-Life

Depending on an individual user’s sensitivity to a drug’s active ingredient, the medication’s effects will certainly be felt throughout its half-life and might linger well beyond that point. In fact, many Cialis users report that a 10- or 20-milligram pill’s effects are felt for up to 36 hours. Cialis’s long-lasting effects have earned it the nickname of “the weekend drug” because a pill taken at 9 p.m. on Friday might not wear off completely until about 9 a.m. on Sunday.

If you’ve got a romantic weekend planned, Cialis could well be the ideal drug for you. However, the longer a drug’s active ingredient is still in your system, the longer you’ll be exposed to its possible side effects.

Side Effects Usually Mild

Fortunately, the side effects of Cialis are generally mild and may disappear altogether upon continued use. Here again, the individual’s sensitivity to the drug’s active ingredient dictates in large part what, if any, side effects he may suffer.

The most common side effects of Cialis are headache, back pain, dizziness, diarrhea, facial flushing, low blood pressure, muscle pain, runny or stuffy nose, nausea, and stomach upset. Some who take the medication experience no adverse effects at all, while others may experience multiple side effects.

The drug’s more serious side effects include a sudden loss of hearing and/or vision or an erection that persists for four hours or more. If you experience one of these more serious symtoms, you should seek medical care immediately.

Other ED Drugs Don’t Last as Long

As previously noted, all the other ED drugs currently available have significantly shorter half-lives than Cialis. And that being the case, the duration of those drugs’ side effects, most of which are similar to those of Cialis, are significantly shorter as well. As you’ve already seen, sildenafil citrate, Viagra’s active ingredient, has a half life of three to four hours, while that of vardenafil hydrochloride, the active ingredient in Levitra and Staxyn, is four to six hours. Avanafil, the active ingredient in Stendra, has a half-life of three to five hours.
