Sildenafil Citrate – A Comprehensive Review

Erectile dysfunction (ED) is a common medical condition amongst middle-aged and older men. It makes it impossible for man to get an erection, or makes it hard to sustain an erection. This can affect the quality of life of anyone who has ED.

Fortunately, science has made it possible to create a drug that can reverse ED. 

What is sildenafil?

Commonly sold under the brand names Pfizer Revatio and Viagra, Sildenafil Citrate is a chemical ingredient used for the treatment of erectile dysfunction. As Revatio, sildenafil is used as a treatment option for pulmonary arterial hypertension. It is known to improve the capacity for exercise in women and men. You should not take Viagra if you are already taking Revatio.

Sildenafil is a drug that is only administered under prescription. It is available as a tablet and as a suspension. Both forms of sildenafil are orally administered. It is also possible to get this drug as an IV fluid, which can only be administered by a medical practitioner.

You can also get sildenafil as a generic alternative, which costs less than the brand version. However, with Viagra generic drugs, they may not be as powerful as the original versions.

How does sildenafil citrate work?

Sildenafil is a type of ED treatment drug that belongs to the PDE 5 inhibitors. This is a class of drugs that work in the same way for men with erectile dysfunction.

This drug works to increase blood flow to the penis. This is achieved by causing the blood vessels in the penis to dilate and allow more blood to flow. This causes the penis to stiffen, making it possible for the man to enjoy sexual intercourse.

Is sildenafil citrate safe?

Generally, Viagra is safe for use when done in moderation and according to the doctor’s orders. Even so, taking it can sometimes cause side effects.

Based on Viagra clinical trials, side effects can include:

  • Nasal congestion
  • Headaches
  • Indigestion
  • Impaired vision
  • Light sensitivity

Though uncommon, the use of Viagra can also cause a condition that makes the eyes see a tinted blue coloration in objects.

Viagra and Drug interactions

If you are living with HIV and taking protease inhibitors, you should not take sildenafil citrate before discussing it with your doctors first. These inhibitors raise the risk of suffering from severe side Viagra effects.

25mg of Viagra at a time is the recommended dosage for HIV patients.

Anyone taking alpha-blockers should not ingest them immediately after using Viagra. They should give the medication at least a 4-hour gap. Failure to do so will result in very low blood pressure, which can be dangerous.

Can you take Viagra with high blood pressure?

It is relatively safe to take sildenafil citrate with high blood pressure. However, you should avoid taking Viagra with nitrates. If you do, it will cause a drop in blood pressure, which can be life-threatening. 

Do not take Viagra if:

  • You are taking the medication with nitrates, nitric acid donors, or organic nitrites as ingredients.
  • You suffer from severe liver impairment
  • You have serious heart conditions
  • You have kidney disease
  • You are living with a renal disorder that is hereditary
  • You are hypotensive

Taking Viagra – How It Works

Viagra for men makes it possible for men with erectile dysfunction to achieve an erection and be able to sustain it. Once a man is sexually aroused, Viagra can help to improve how the body responds to stimuli. However, Viagra does not help with sexual stimulation. In the absence of sexual stimulation, Viagra does not work.

Once a man is sexually stimulated, the body’s nervous system releases nitric oxide to the blood tissues in the penis. This oxide stimulates an enzyme that produces cyclic guanosine monophosphate (cGMP), a chemical messenger. cGMP promotes the dilation of the arteries in the penis thereby allowing the tissues in the penis to fill with blood. This results in an erection.

When Viagra is taken, it prevents the degradation of cGMP. This is what makes it possible for someone with erectile dysfunction to hold an erection for longer.

Sildenafil citrate dosage

Viagra is available in a diamond-shaped, blue pill. You can get it in twenty-five grams, fifty grams, and a hundred grams tablets. It is recommended that one should take only one pill every twenty-four hours. It is preferable to take Viagra half an hour to one hour before sexual intercourse.

Overdosing on Viagra

Symptoms include:

  • Blurred or distorted vision
  • Vomiting
  • Optic neuropathy
  • Optic nerve swelling
  • Blindness
  • Diarrhea
  • Break down of muscles

Overdosing on Viagra can have serious side effects. If you accidentally overdose on Viagra, it is advisable to contact your doctor as soon as possible.

Sometimes, death can occur from an overdose of Viagra.

Precaution while taking Viagra


If you are allergic to sildenafil, you should tell your doctor or pharmacists. Also, let them know if you have any other allergies before prescribing Viagra. Sometimes, Viagra may have an active ingredient that will cause allergic reactions to you.

Your medical history

Always let your doctor or pharmacist know about your medical history before getting a Viagra UK supply. This is especially if you suffer from any of the conditions mentioned above.

Never take Viagra as a recreational drug. It can cause serious side effects and can cause permanent erectile dysfunction. Viagra should only be taken by people who have erectile dysfunction.

The price of Viagra

According to the Pfizer Viagra website, the wholesale price for original Viagra is $61.54 for 50mg o 100 mg Viagra. Viagra generic tablets go for $30 and $35 per pill.

Note that these are not fixed rates. You can search for online Viagra selling websites to get the best prices in the market.

Always ensure that you purchase from reputable dealers to get real Viagra.

When to see a doctor

If you notice any side effects after the use of Viagra, you should stop usage and contact your doctor immediately. Never self medicate with Viagra. Always ensure you follow the doctor’s directions.
