Viagra Vs Sildenafil: Meaning, Dosages, and Differences Explained

Viagra might be the most well-known prescription medication for treating erectile dysfunction (ED), but it is not the only option. Its active ingredient, Sildenafil Citrate, is also available in a more affordable generic version, simply known as Sildenafil.

Viagra is a well-known brand that contains the molecule Sildenafil Citrate, offering various dosage options to meet individual needs. Doctors recommend the most appropriate dosage based on a patient's specific requirements.

Understanding these differences can help you make an informed decision that aligns with your health and budget. Continue reading this blog to explore detailed insights into Sildenafil citrate, including its dosage options, uses, potential side effects, and more.

What is Viagra?

Viagra is a branded oral tablet used for the treatment of erectile dysfunction (ED). It was initially developed for heart conditions but later proved effective for ED and received FDA approval in 1998. The active component of Viagra is Sildenafil Citrate, which improves blood flow to the penis. This increased blood flow causes an erection and maintains it during arousal. Viagra is available in three main dosages, i.e., 25 mg, 50 mg, and 100 mg, allowing doctors to recommend the most suitable option based on individual needs. Typically, Viagra is taken orally 30 to 60 minutes before sexual activity, though it can start working in as little as 12 minutes for some users. The dosage effect usually lasts 4 to 6 hours, though factors such as your age, metabolism, and overall health can influence its duration.

What is Sildenafil?

Sildenafil citrate is the active molecule contained in Viagra. It functions in the same way as Viagra and leaves the same effect on the body. Sildenafil functions by blocking the PDE5 enzyme, which helps relax blood vessels and improve blood flow.

Beyond treating ED, Sildenafil is also approved by the FDA under the brand name Revatio for the treatment of pulmonary arterial hypertension (PAH), a condition affecting the lungs. It helps improve exercise capacity in both men and women with PAH.

How are Viagra and Sildenafil Related?

Viagra, consisting of the active molecule Sildenafil, is quite popular among individuals suffering from erectile dysfunction.

Sildenafil is a molecule manufactured and sold under various brand names, including Viagra, and has the same effect regardless of the brand. First introduced to the market in 2011, Sildenafil made it possible for other pharmaceutical companies to produce and sell a more affordable alternative to Viagra.

Both these medications can be bought with a prescription. However, Pfizer has introduced Viagra Connect in certain countries, such as the UK, where it is available without a prescription.

What are the Side Effects of Viagra vs. Sildenafil?

Since both Viagra and Sildenafil are similar, their side effects are also the same. It is important to be aware of these potential side effects and to seek medical advice if necessary.

Here is a list of common side effects of Viagra and Sildenafil:

Blocked nose
Headaches
Back and muscle pain
Nausea
Indigestion
Changes in vision (examples include, change in colour, mind blurring, and others)
Facial flushing

However, all these side effects resolve on their own once the medication's effect wears off. There are some rare and serious side effects of Viagra and Sildenafil. If you experience any of the following, seek medical attention immediately:

Loss of hearing
Loss of vision
Dizziness and lightheadedness (usually occurs due to a combination of low blood pressure and other medications)
Priapism (occurs when erection lasts for more than four hours, which can be painful at times)

Consult a doctor if these severe side effects persist or worsen over time.

Viagra vs Sildenafil: What’s the Difference?

Here are some key differences between Viagra and generic Sildenafil medications:

Features	Viagra	Sildenafil
Dosage	Viagra is available in three standard dosages: 25mg, 50mg, and 100mg.	Sildenafil offers the same options but also provides additional flexibility. Some manufacturers produce a 20mg version, which is sometimes prescribed in multiple tablets to adjust the dosage.
Manufacturer	Viagra is exclusively developed and manufactured by Pfizer, ensuring consistent formulation, branding, and quality control.	Sildenafil is produced by multiple pharmaceutical companies, which may lead to slight differences in non-medical ingredients such as binders, fillers, or colouring agents. However, these variations do not impact the effectiveness or safety of the medication.
Cost	Pfizer, the manufacturer of Viagra, is quite expensive, mainly because of its brand recognition.	Sildenafil citrate is produced by multiple manufacturers, making it a more affordable alternative. This price difference often plays a key role in purchasing decisions.
Appearance	Viagra is most commonly recognised as the “little blue pill” in the market. The shape and colour of it are easily recognisable.	Sildenafil Citrate’s appearance varies across manufacturers, who produce it in different sizes, shapes, and colours.

The three available dosages of Viagra tablets are:

This dosage, however, varies for children. Dosage varies between 10 mg and 20 mg, three times a day, depending on body weight.

Viagra vs Sildenafil: Which is Better?

Both Viagra and Sildenafil use the same active ingredient in the treatment of erectile dysfunction by enhancing blood flow. The difference lies in the fact that Viagra is a well-known brand name, and Sildenafil is its active molecule.

Are There Additional Options?

While Viagra and Sildenafil citrate are highly effective for treating erectile dysfunction (ED), other medications might better suit your needs. Here are some additional ED treatment options to consider:

Avanafil, also known as Stendra, starts working within 15 to 30 minutes. It is designed to specifically target ED while causing fewer side effects lasting for up to 6 hours.
Vardenafil: It lasts usually up to 6 hours. As soon as you take this medicine, it starts working within 10 minutes or less.
Daily Tadalafil: It stays active in your body when you take it as a low-dose pill every day. This medicine dosage does not need to be planned around sex; thus, it is a preferred option for those who prefer flexibility.

Each of these options has its unique benefits. Consult a healthcare provider to help you choose the correct dosage that meets your needs and preferences.
