VIAGRA (sildenafil citrate) – Brand vs Generic Alternatives Online Price Comparison

Pharmacy Board (PTCB)


Brief overview about Viagra

There is a short story behind Viagra invention. Two scientist of Pfizer Drug Company named Albert Wood and Peter Dunn was trying to invent a medicine for treating angina (a heart disease which results in severe pain in chest) and high blood pressure. By doing various research works they came up with a medicine which was chemically named as sidenafil citrate.

But the result which obtained was somewhat different. The intention of scientists was to dilate the blood vessels around heart, so that the heart gets adequate blood supply and also to increase the concentration of oxygen in blood. But instead of making increased blood supply in heart, the medicine helped to increase the blood supply in all body parts.

Users realized that the drug is helping them to keep their penis erected for longer time and people with erectile diseases found a solution to their problem. Thus, the drug became very popular in a short time span because many people suffering from erection problems started to use it. Finally the drug sidenafil citrate was named as Viagra and it is prescribed by physicians to treat erectile dysfunction disease.

Working mechanism of Viagra

Sidenafil citrate is taken only when it is prescribed by a doctor. This drug helps to increase the blood flow in penis, thus keeps it erect for longer time. But to feel its effect you need be sexually aroused. Researches reveled that this drug can be used to treat all types of erection related diseases. To get a proper action this medication needs to be consumed 30 to 60 minutes before having sexual intercourse, and its effect can last for up to 4 hours.

Erectile dysfunction disease

Erectile dysfunction is a disease which affects around 50 percent men across the world. In the United States more than 30 million people are affected by this disease. Mainly it affects people whose age is above 40 years and some people face this problem due to genetic issues.

This disease occurs when the blood vessels in penis do not get dilated or amount of blood flow is reduced. Due to reduction in blood flow people face either no erection or they cannot hold the penis erected for longer time. People are advised to visit a physician it they face this type of problems.

Causes of erectile dysfunction (ED)

The main causes of ED cited by doctors include genetic problem, high cholesterol, blood pressure, and hyperglycemia. Other conditions include alcoholism, smoking, depression, and anxiety related diseases.

Erectile diseases do not only affect your life but also affects your partner’s life. Sex is an integral part of life and if people cannot enjoy it, there will be complications in a relationship. Still now many people feel awkward to speak about sexual diseases or problems. But once you start sharing your problem with a physician you will feel much more relieved and they will guide you in a proper direction.

It is estimated that more than 23 million men have consulted a physician about their problem and now they are enjoying their sexual life. But the thing is that people have to come forward about their problems without any hesitation.

Proper self assessment is also required to identify this disease. If you are facing any problem while having sex such as erection time, no erection, no sexual arousal etc. then you should go to a doctor to seek some advice on your problem, because medicines like Viagra is not suitable for all people.

Assessment-Based Certificates

Assessment-Based Certificates evaluate learning outcomes from a PTCB-Recognized Education/Training Program and/or work experience for the specific certificate, do not expire or require maintenance, and do not award an acronym after the name. PTCB offers two certificate programs:


    In most of the cases doctor recommends 50 mg Viagra or they start with 25 mg of this drug. But depending on the action of a dose the doctors sets up future dosage. Sometimes the dose is increased to 100 mg or at times it may be reduced to 25 mg as per your requirement. The doctor will guide you according to requirement. Generally one tablet daily is prescribed for erectile dysfunction diseases.

    But, after consuming the drug if you have some problem or complication then immediately you should consult your physician. It is also important to consult your physician before taking Viagra because it is not suitable for everyone; it depends upon your present health condition. The medicine can be taken in both empty stomach or after meals. But consuming high fatty foods are not recommended before taking Viagra, because it slows down its absorption and gives a delayed result.

    Researchers have found out that both 100 mg and 50 mg dose of Viagra has helped more than 80 percent people with stronger erection for more time.

    First dose

    The pill should always be taken before sexual intercourse and it takes 30 to 60 minutes to get activated. But you are required to be sexually aroused to get proper result, because it does not helps in erection without being sexually aroused. The pill can also be consumed 4 hours before having sex, as there will be no effect unless you are sexually stimulated. And if the dose does not work for you for the first time then your physician may increase it.

    Viagra Side effects

    Some of the general side effects of sidenafil citrate or Viagra include nausea, headaches, upset stomach, blurred or impaired vision, runny nose, dizziness, sores on back portion, muscle sores, skin rash, and flushing. These symptoms occur within few hours after consuming the pill.

According to law Viagra cannot be sold in offline or online shop without a prescription. Most of the reputed stores and online shops follow this rule. But some pharmacies do not follow it and sells Viagra or it’s alike without any prescription.

Most of the people nowadays prefer buying medicines online, but there are few things which should be taken into account before making purchase are described here:

  • If you find that the online shop is agreeing to sell medicine without a valid prescription then it may not have a legal authorization to sell Viagra or other medicines.

  • Viagra or sildenafil citrate is available in market only in three strength viz. 25 mg, 50 mg, and 100 mg. Any strength apart from this may be an indication of duplicate or fake medicine.
  • You have to crosscheck the medical shop if they are selling generic Viagra, because generic Viagra is not still available in the market due to patent issues and generic version of this drug has not got FDA approval still now. Availability of generic Viagra is an indication of fake or unapproved medicine.

Herbal Viagra

Many people wonder about herbal Viagra. Some herbal medicine manufactures sells sex arousal pills and claims that it would have same effect as Viagra, and these pills cause no side effects because it made from natural sources. But it is not true; there is no herbal composition for Viagra.

No herbal Viagra has been approved by the FDA till now, so you must remain cautious if any pharmacist make such claims and tells you to buy an herbal Viagra as it is same as the general Viagra. And this unapproved drug can also cause some health problems because no one is sure about its composition.  Just make it sure there is only one Viagra available throughout the world and it can only be bought if you have a valid prescription.

Natural Viagra

Although there is no herbal Viagra but there is a way to get natural Viagra. Effectiveness of this natural Viagra is not tested in any laboratory. People claim that this process worked for them and enhanced their sexual desire and power.

To get natural Viagra people used to boil watermelon juice after extracting it. The boiling is done by adding lemon juice and it is continued till half of the juice gets evaporated. Then the cooled juice is consumed to get extra sexual arousal. Experts believes that chemical components in watermelon like lycopene and citrulline helps to increase the sexual stimulation and also increases the blood flow in different body parts including penis which helps to maintain erection for people suffering with ED.
