Sildenafil 20 Mg for ED: Dosage, Brand Names and Value for Money 

Sildenafil is the drug 99.9% of doctors prescribe when it comes to treating patients with high blood pressure in the lungs (pulmonary hypertension). In oral doses of 5-20mg (or as prescribed by your doctor), Sildenafil Citrate works by relaxing and widening the blood vessels in your lungs which allows the blood to flow more easily. It decreases high blood pressure in the lungs thereby strengthening your heart and lungs to work better and improves your ability to exercise. This medication is not recommended for use in children.

Sildenafil Dosage for ED

Though Sildenafil Citrate is well known for its antihypertensive properties, this isn’t the real deal behind its popularity. The real deal behind the popularity of Sildenafil, also known by brand names such as ‘Viagra’ and ‘Revatio’ (both manufactured by Pfizer) is its effectiveness in treating male sexual function problems (impotence or erectile dysfunction-ED). The usual adult dosage of Sildenafil for ED is an initial 50 mg ingested orally one time a day, as required, one hour before sexual exercise, maintain the dose by ingesting 25 to 100 mg of Sildenafil orally one time a day, as required, one hour prior to sexual activity, the drug may be consumed around half an hour to 4 hours prior to sexual activity (this information is not a substitute for medical advice. Do well to consult your doctor or pharmacist). When combined with sexual stimulation, Sildenafil functions by increasing the flow of blood to the male sex organ to help a man get and sustain an erection.

Viagra (Sildenafil Citrate) from Pfizer – Currently the most effective treatment for ED

Considering the effectiveness of Sildenafil for ED, it varies from brand to brand and sometimes from person to person. For example, the period of time for which Viagra lasts varies from by individuals though it has been known to function for up to 5 hours at a time, when combined with sexual stimulation. Most men discover, however, that the pill’s effects will start to wear away 2-3 hours after first taking it.

Sildenafil 20 mg vs Levitra

One thing to note is that Sildenafil is a generic name of the drug, it has brand names such as Viagra, Revatio, Levitra, Cialis, etc. whose main active ingredient perform the same function which is anti-erectile dysfunction. Levitra tablets 20mg are for treatment of erectile dysfunction (impotence) in male patients, which is inability to obtain or maintain an erection necessary for sexual activity, due to deficient flow of blood into the male sex organ. Levitra 20mg tablets work by relaxing the blood vessels in the male sex organ to increase blood flow leading to an erection, which is the typical response to sexual stimulation, however, the drug will only work if you are sexually aroused. Levitra 20mg tablets should be taken within an hour of planned sex and in most cases it helps you to get an erection in about 30 minutes that will last for around 4 hours, provided you are sexually aroused, the drug does not work well if you are not aroused.

Where Can I Buy Sildenafil Citrate Online?

Most anti-erectile dysfunction drugs are strictly prescription-only, which means that the drug is ineligible for over the counter purchases, making it hard for some buyers without access to doctors to get a hold of the drug. Considering the above fact, buyers commonly search online for over the counter Sildenafil Citrate products in the hope of at least procuring generic versions of Viagra without a need for providing prescriptions, but is there such thing as over the counter Sildenafil products? This is where value for money comes in.

Sildenafil 20 Mg Pricing

Trusted online drugstores are a great place to start. Generic Sildenafil Citrate products are abundant online because that most generic drug suppliers commonly advertise their products online. As regards pricing, generic Sildenafil products are also cheaper as with other generic drug products compared to branded drugs. In major online drug stores, a 30-pill bottle of generic Sildenafil 20mg goes for about $37.73 – $138.00 while a 24-pill bottle of brand Sildenafil like Viagra 25mg goes for about $192.91 – $441.95. Regarding their prescription status, some generic Sildenafil Citrate products can be bought without prescription and “over the counter”. How come? Some online drugstores allow consumers to purchase generic Sildenafil Citrate products without prescription but with the following provisions:

  • These stores ship out Sildenafil Citrate products without prescriptions under the assumption that the buyers are actually prescribed with the drug
  • Some stores usually offer online consultations or online medical assessments for the buyers before dispensing the product
  • Other online pharmacies at least recommend that buyers check if they have Sildenafil Citrate allergies first before purchasing the generic Sildenafil Citrate available


Health scientists have not discovered a better substitute for Sildenafil Citrate products as drugs for ED. Until such a discovery is made, the popularity of Sildenafil as an effective ED drug will only continue rising. Regardless of their brand or generic status, Sildenafil Citrate products like Viagra and its generic alternatives should be purchased with prescriptions, whether consumers can find them on online pharmacies or at their local drugstores. Sources that dispense no-prescription Sildenafil Citrate products are usually shady (although there are some exceptions like the ones presented on this write-up), as the law enforces that all prescription products should be dispensed only when consumers can provide valid, written doctor scripts for the products.

There are a lot of negative consequences to sourcing over the counter Sildenafil online:

  • Consumers may be given counterfeit products
  • Consumers may be incompatible with the drug and eventually, have adverse reactions
  • Consumers may be ripped off by the scam stores that promised them OTC dispensing of Sildenafil Citrate products

Because of these reasons, buyers should be wary of sourcing “OTC” Sildenafil Citrate online to avoid fake products and scammers who take advantage of clients online. Buyers must also consult their doctors before deciding to use Sildenafil and get assessed first to rule out possible adverse reactions prior to using the drug. If you need to source your Sildenafil Citrate products online, make sure that you check the vendors you are purchasing from and also make sure that you are actually safe to use Sildenafil Citrate products, brand-name or generic.
