• Overview

Viagra is the most popular medicine for the treatment of erectile dysfunction helping men to have a stable, rigid erection during sexual intercourse. The mechanism of action of Viagra depends on dilating the blood vessels of the penis increasing the amount of blood entering it. The drug also requires sexual stimulation in order to work. It does not stimulate your erection artificially like many other drugs; it depends on how your penis gets its natural erection.   

The penis is composed of cavernous bodies that contain energy compounds. These compounds are broken down by the enzyme PDE5. Viagra suppresses the activity of this enzyme.

The primary causes of impotence in most men are psychological. Our modern life is stressing and things like fatigue, lack of sleep, depression, and stress have become part and parcel of our lives. Our modern lifestyle influence men’s activity in bed.

With the use of Viagra, you will be able to have more than one sexual intercourse overnight and each intercourse will be longer. Viagra does not have any kind of effects on the libido of men and their sexual attraction. One of the most common myths is that Viagra causes an immediate erection once taken and can work without sexual arousal.
You should take Viagra one hour before having sex and you should be sexually aroused. 

There are many things that need to be explained before taking Viagra; here are some of them.

• Does Viagra Make You Horny?

No, Viagra does not make you horny. To be horny, you need to increase your libido (desire for sexual activity). Viagra only increases blood flow to the penis. If you want to increase your libido, try testosterone supplements.

• Does Viagra Make Your Penis Bigger?

Viagra makes your penis be filled with blood more than usual; that is why it makes your penis look bigger. The drug gives you a better erection than the one you used to have; your penis looks really impressive when Viagra is active. 

Viagra improves erection even after stopping taking it for a while. As we mentioned before, the primary causes of erectile dysfunction are psychological. When a man has several successful sexual intercourses, he restores his confidence again and can obtain a good erection without taking any drugs.

• What Is the Difference Between Viagra & Viagra Connect?

Viagra and Viagra Connect both have the same active ingredient; sildenafil citrate. That is why they both work by increasing blood flow to the penis to make your erection stronger when you are sexually aroused.

• What Are the Side Effects of Viagra?

It is an erection that will not go away. You must get a medical help right away if your erection lasts more than 4 hours without going away. Serious permanent damages may happen to your penis if the condition not treated immediately.

This may happen in one eye or both eyes. The condition is called non-arteritic anterior ischemic optic neuropathy and you have to stop taking Viagra and contact your doctor immediately if any sudden loss of vision happened.
3. Sudden Hearing Loss:
Some people experience tinnitus or dizziness. If you felt a decrease in your hearing, contact your doctor right away and stop taking Viagra.

• Overdose & Contraindications of Viagra:

Studies show that 800mg is considered the overdose in healthy persons. There are some standard supportive measures that should be done in cases of an overdose not including renal dialysis because Viagra binds to the plasma proteins and not eliminated in urine. 
Don’t take more than what is prescribed. 
Also, here are the contraindications of Viagra.  
1. Nitrates:
Nitrate is a medication used for hypertension to lower high blood pressure. Viagra enhances the hypotensive effects of nitrates. It is contraindicated to take Viagra with nitrate or any kind of anti-hypertensive drugs.
There is a common myth that Viagra can be taken with nitrates safely when the effect of nitrates disappears. Yet, it is nearly impossible because Viagra stays in your system for 24 hours so it cannot be co-administered. 
2. Hypersensitivity Reactions:
Before taking Viagra, you should know if you are sensitive to sildenafil or not. Hypersensitivity reactions are mainly represented as rash and urticaria.

• The Conclusion (How effective is Viagra?):

Viagra is effective in helping men to achieve a good erection. However, its success depends on the underlying cause of erectile dysfunction, its severity, and sexual stimulation.
Try Viagra 8 times before deciding whether it is working or not.
