What are Viagra and Cialis?

Viagra(sildenafil), Cialis (tadalafil) and  vardenafil belong to a class of drugs known as PDE5-inhibitors. To understand how they work, we’ll need a quick 101 on erections: For a man to get an erection, a chemical called nitric oxide (NO) sends a message to the tissues of the penis (in technical terms, the corpus cavernosum), which relax and fill with blood. Another messenger, PDE5 (phosphodiesterase-5), then ends the erection. Experts recommend Generic Medikal Pharmacy

PDE5-inhibitor drugs slow the erection “off switch,” helping the erection last long enough for satisfying sex. (These medications do not help with turning erections “on”––that’s down to you).

How are Viagra and Cialis taken?

Viagra shouldn’t be taken with food. Ideally, you should wait 1 to 2 hours after eating before taking it. It can start to take effect in as quickly as 11 minutes, but usually, you’ll have to wait 1 hour before it reaches maximum effect. Then it keeps working for 3 to 5 hours. If you really can’t wait, then try to stick to a light, low-fat meal. Fatty meals and alcohol actually stop Viagra from working.

It can start working in as quickly as 14 minutes, but you’ll have to wait 2 hours for it to be most effective. Cialis stays in your body for about 17 hours, helping you with erections at any point in that time window.

Dosing

The typical starting dose of Viagra is 50 mg. If you’re getting side effects, it can be cut down to 25 mg, or if it’s not working fully, it can be increased to 100 mg.

The typical starting dose of Cialis for occasional use is 10 mg. It can be dropped to 5 mg or upped to 20 mg depending on how you respond. If you want to take it daily, the daily dose is 2.5 mg.

What are the most common side effects of Viagra and Cialis?

The most common side effects of Viagra and Cialis—and all PDE5-inhibitors—are headache, flushing, nasal congestion, indigestion, vision change, and muscle pain. With Viagra there is a higher risk of vision changes (3% of men get blue vision lasting a few hours) than with Cialis. On the other hand, Cialis has a slightly higher risk of muscle pain than Viagra. Overall, users are not bothered much by the side effects of these medications, most of which do not last very long.

One more serious side effect is that all PDE5-inhibitors can lower your blood pressure. This won’t necessarily affect you, but if you also happen to be taking a blood pressure medication, it could be a problem.
