For how long is Cialis effective?

Tadalafil, better known under the brand name Cialis, is a drug used to treat erectile dysfunction (ED) and male impotence quite effectively. Very much like Viagra, it has gained massive popularity among men in the world and has changed the sex life of many. It has also surpassed Viagra in certain ways – and it owes this success to one amazing aspect – its long window of effectiveness. 

How long do the effects of Cialis last?

Other similar medicines, like Levitra and Viagra are designed to be taken within 30 – 60 minutes before planned sexual activity. The effects of the drug can last 4 to 5 hours as it remains in the bloodstream. However, you shouldn’t expect a 4-hour long erection – the drug just allows you to achieve and sustain it whenever you are in the mood in the given timespan.  

In comparison with quite decent 4-5 hours, Cialis is praised for an amazing 36 hour duration of effectiveness. In other words, the active substance (Tadalafil) can help trigger and maintain any number of erections for the following day and a half. For this reason, Cialis is also called “the “weekend drug”. Being the third PDE5 inhibitor invented after Levitra and Viagra, its long lasting window of effectiveness has returned spontaneity and invigorated the sex life of many couples, making it one of the most popular drugs for the treatment of ED. 

What is the secret of Cialis – how does it work?

The generic name of Cialis comes from its active ingredient – Tadalafil. This chemical is designed to inhibit an important enzyme – phosphodiesterase-5 – better known under the abbreviation PDE5. This enzyme plays an important role in the biochemistry of your blood, but can pose a challenge if you cannot achieve a satisfactory erection.

When an erection is triggered, the blood vessels (arteries) in the penis expand and the heart pumps blood that reaches and fills the penile spongy tissues.  Other blood vessels (veins – specialized to return blood into the circulatory system) contract, which increases the blood pressure and helps the erection remain stable during sexual activity. After ejaculation, PDE5 helps the blood return to the system, thus the erection ends. 

An enzyme that governs the whole process is known under the abbreviation cGMP. It regulates the whole process of relaxation and constriction (contraction) of penile blood vessels. Studies have shown that men that do not struggle with impotence and ED have a normal flow of cGMP.

Men who face challenges from erectile dysfunction and impotence, can blame it all on the untimely activity of PDE5. In fact, this enzyme can act prematurely and start to disrupt and even destroy molecules of cGMP, causing the blood vessels that hold the pressure to expand and return blood from the penis into the bloodstream. The results are known to be inconvenient and even slightly embarrassing, but men don’t have to fall into despair. 

Before the PDE5 molecules can sabotage the function of the ever-helpful cGMP, Cialis can jump in for help and block it – which gives you enough time to achieve and sustain a healthy erection. Your piece of mind is thus preserved and you can continue to enjoy sex without unpleasant surprises 

Will Cialis trigger an erection without sexual arousal?

When it comes to treating impotence and assisting in regular and stable erections, Cialis has proven to be a very powerful ally of many men all over the world. However, it is no miracle drug – it will not produce a sudden arousal or boost your libido. 

Just to clarify this once again – Cialis and other PDE5 inhibitors work by:

  • relaxing the muscles in the blood vessels that fill the penile tissue 
  • constricting other muscles that prevent the blood from leaving the penis prematurely. 

Cialis has no means to incite sexual desire or excitement, so you would need to be primarily physically (and mentally) stimulated. Sometimes, some minor changes to the setting or breathing exercises can help you relax and get you started. 

Please consider that erectile dysfunction can be related to or caused by many underlying conditions. If the main issue you are struggling with is a lack of sexual desire or will, it is best to have a conversation about this with a doctor or a trained specialist. Keep in mind that none of the PDE5-Inhibitors, be it Cialis, Viagra and Levitra, can change the biochemistry of the brain. It is therefore recommended to check the levels of sexual hormones, side-effects of other medications you are using or to look into other potential diseases, so don’t hesitate to talk with a medical professional. 

How does the daily version of Cialis work?

It has already been stated how Cialis expands the window of effectiveness in comparison with other competitors (Levitra and Viagra). However, you would still need to take it at least 30 minutes to 2 hours before any potential sexual activity, as it first needs to be absorbed into your bloodstream. Cialis Daily is advertised as the option that is best for people who don’t want to make precise plans.

This version of Cialis is meant for daily use – you can take one in the morning or afternoon, same time each day.  Daily tablets of Cialis are produced in doses of 2.5mg or 5mg, while the normal Cialis tablet is sold in doses of 10mg and 20mg.

The active ingredient, Tadalafil, remains in the bloodstream for as long as necessary, so you can have sex at any time during the day – when ever you are in the mood – without worrying about your biochemistry failing you.   

How and where to purchase Cialis?

Cialis and Tadalafil in various dosages are available as prescription-only drugs. You can purchase the medicine in your local pharmacy or online, but you should first talk with your doctor in order to obtain a prescription. Some online pharmacies offer an option of filling in a consultation form before fulfilling your order, yet we recommend that you talk to a physician to inform yourself about side-effects and whether Cialis is the best option for your condition.
