The drug Cialis is popular because you can take it every day. But should you?

If a doctor has prescribed Cialis for pulmonary arterial hypertension, you may be advised to take two 20-mg doses a day. But taking that much of the medication should be done only under a doctor’s guidance. While Cialis works for ED by affecting the PDE5 enzyme cialis 10mg tablet in the penis, it also affects other PDE enzymes in tissues and cells in other areas of the body. For example, PDE5 is found in tissues in the lungs, kidneys, liver, brain, and platelets. Cialis also affects PDE11, which is found in tissues in the: corpus cavernosum, one of two columns of spongy tissue that runs through the penis Doubling the maximum dose of Cialis to 40 mg can increase the chances of experiencing side effects, which include: Priapism is an erection lasting longer than 4 hours caused by not enough blood leaving the penis, leading to low oxygen levels.

Other Interactions

The most severe type is ischemic priapism, which requires urgent medical intervention to avoid long-term damage to penile tissue. Another reason not to double your dose is the long-lasting effects of Cialis. Cialis’s effects last much longer (up to 36 hours) than those of other PDE5 inhibitors like Viagra (4 to 5 hours). So, Cialis stays in your body and clears slowly. Adding doses on top of what’s already in your system can increase the risk of side effects. If you’re nervous or anxious, this affects your arousal and ability to get or keep an erection.

Mechanism of action

That's right – all of the medications approved by the FDA for the treatment of ED are PDE5 inhibitors, which stands for phosphodiesterase-5. PDE5 is an enzyme that breaks down cGMP in the body. CGMP is a substance that's central to getting a firm erection. It promotes increased blood flow in the penis, leading to more blood (as much as 7x normal!) and swelling. As spongy tissues in the penis fill with blood, the dorsal vein at the top of your penis is compressed, helping to keep blood trapped in the penis.

Who should not use tadalafil?

The blood continues to flow in and can't escape – an erection forms. PDE5 is the enzyme that breaks down and removes cGMP. It's a natural enzyme that helps bring erections back to normal after intimacy. It's a little like the brakes on a car. By stopping PDE5 from doing its usual thing – acting as a brake system – an erection can happen more easily.
