Facts about Viagra men ought to know
Viagra may clearly be the number one choice for men facing erectile dysfunction. Yet even after many years after its introduction, there are plenty of new users who are full of queries about Viagra . This article lists some of the most frequently asked questions about Viagra and its use. Hopefully this would quench your thirst for more information about Viagra:
What is the mode of action of Viagra?
Viagra works by blocking an enzyme which prevents an erection. To understand its mode of action more scientifically, you need to know that an erection happens when a man is sexually aroused or stimulated. This causes a chemical called cyclic GMP to be produced. This chemical is the trigger for an erection which causes the penile arteries to expand while the veins narrow. In other words, it increases the blood flow to the penis area. This causes the penis to get hard. Viagra stops an enzyme which tends to block cyclic GMP, thereby ensuring that there is more cyclic GMP which can be produced which flows in to the penile area unabated. This guarantees a long lasting erection.
Is it a sex stimulant which can be used by women also?
Viagra is not a sex stimulant. Its use is restricted to correcting erectile dysfunction in men, where despite being sexually aroused, the man can not achieve a hard penis disabling him to have any sexual intercourse. It is not recommended for use by women.
Can Viagra be used even after reaching orgasm?
Some men have used it to ‘prolong’ their sexual pleasure. While it works for some men, some are of the opinion that they can not bear any further stimulation after a successful orgasm.
Are there any precautions to be taken before taking Viagra?
The onset of action of Viagra may be delayed if the consumption is preceded by a fat-rich meal. It is also recommended to avoid eating grapefruit or drinking grapefruit juice while you are on this medication unless your doctor instructs you otherwise.
What is the recommended dosage of Viagra?
Viagra is to be taken orally at least 30 minutes, but no more than 4 hours, before sexual activity (1 hour before is the most effective). It is recommended not to take more than once daily and take according to doctors’ advice. It is important to remember that the dosage is based on your current health, your existing medications and response to therapy. It is always better to consult your doctor before taking Viagra.
Can Viagra protect me from STDs?
No oral ED pill can protect the user from STDs like HIV, hepatitis B, gonorrhea, syphilis, etc. For this you have to practice ‘safe sex’ and use condoms.
Where can I buy Viagra from?
Viagra is available in plenty of online and offline pharmacies.
Is the cost of Viagra covered by medical insurance?
