Sildenafil for Erectile Dysfunction

405Sildenafil for Erectile Dysfunction

Sildenafil, or sildenafil citrate, is a wildly popular medication for the treatment of erectile dysfunction (ED). It’s the active ingredient in Viagra, Revatio, and generic versions of these drugs.

Sildenafil is a phosphodiesterase type-5 (PDE5) inhibitor. Phosphodiesterase is an enzyme responsible for regulating blood vessels, and when sildenafil blocks this enzyme, the blood vessels relax and widen. This directly combats erectile dysfunction by improving blood flow to the penis and helping to achieve and maintain an erection.

Viagra by Pfizer is the most well-known sildenafil product for the treatment of erectile dysfunction.

Sildenafil Dosage for ED

Most doctors recommend a starting dose of 50 mg of sildenafil to start with. Depending on how your body reacts to sildenafil, your dosage may decrease to 25 mg, or increase to 100 mg. Taking more than 100 mg of sildenafil has no benefit, so you shouldn’t consume more than 100 mg a day.

Your doctor may restrict your dose of sildenafil further, depending on your medical history. If you’re older than 65 or have severe kidney issues, you shouldn’t take more than 25 mg of sildenafil a day. If you have any liver problems, always speak to your PCP before taking sildenafil. Do not take sildenafil products if you are under 18 years old, are allergic to sildenafil, or have just started alpha blocker therapy.

Viagra and generic variants of Viagra are available in single pills of 25 mg, 50 mg, and 100 mg. Revatio and its own generic counterparts can be found in 20 mg tablets.

How to Use Sildenafil Tablets

Most sildenafil products are meant to be swallowed like regular pills, but chewable tablets and orally-administered liquid suspensions are also available. First and foremost, always read the directions your doctor gives you.

20 mg, 25 mg, 50 mg, and 100 mg sildenafil tablets should all be taken as needed, approximately an hour prior to sexual activity, though if finding time to take your tablets is a problem, anywhere from thirty minutes to four hours before sexual activity is fine. Viagra, Revatio, and generic versions of both can be safely cut in half using a pill cutter from a reputable pharmacy. Swallow these tablets as you would any other pill.

Chewable sildenafil tablets enter your body and begin working faster. Take chewable sildenafil as needed, around thirty minutes before sexual activity. Be careful to always chew this medicine before swallowing.

Oral liquid suspensions may come in a bottle with a measuring syringe, provided by your pharmacy, or in a single-dose foil packet. For liquid suspensions from a bottle, first, shake the bottle well before opening. Then measure out your dosage with the syringe and swallow it. Wash the syringe after each use and store the remaining oral suspension in the refrigerator, if possible. The packaging of your oral suspension should tell you how many mg of sildenafil is in each mL. For example, a bottle with 25 mg/mL would contain 25 mg of sildenafil in each mL. Single-dose packets of oral suspension jelly are much simpler; just open the packet and swallow the contents. Take your oral suspension thirty minutes before sexual activity.

Sildenafil can be taken with or without food unless explicitly stated otherwise on your product’s directions. Taking sildenafil with a large meal can cause it to start working a little more slowly, however. You should avoid taking sildenafil with alcohol, as too much alcohol can reduce sildenafil’s efficacy. Avoid grapefruits and grapefruit juice while on sildenafil, as these can worsen the medicine’s side effects. For erectile dysfunction, only take sildenafil as needed.

Sildenafil Online Price

In addition to local pharmacies and drugstores, sildenafil is available for purchase online with a prescription. All pills and tablets are easy to find, though oral liquid suspensions are much rare. All price approximations are in USD.

20 mg sildenafil tablets are available for roughly $50 to $60 online, though prices can range from $15 for 30 generic tablets to over $4000 for 90 brand-name Revatio. Single pills are also available for less than $1 each.

25 mg sildenafil pills have price range that’s only a little narrower, from $15 per four-pack of generic pills to over $800 for 88 pills of brand-name Viagra. Single pills are available from $0.60 for generics to close to $4 for Viagra.

50 mg sildenafil pills have a wider price range than their 25 mg counterparts; four pills could cost as little as $12, or you might spend as much as $200 or more for 66 brand-name Viagra pills. 50 mg pills are more commonly prescribed than 25 mg pills, and often run cheaper despite containing more active ingredient. If you only take 25 mg doses, it may be more cost-effective to buy 50 mg pills and a pill cutter.

100 mg sildenafil pills range from $14 for a four-pack of generics to over $700 for 88 brand-name Viagra pills.

Chewable tablets will range in price from $55 for ten tablets to over $500 for 360 tablets. Singles are available from roughly $1 to $4. Strangely, some sites will sell single pills of generic brand Kamagra sildenafil chewables for three times the price of single Viagra chewable tablets.

Oral liquid suspensions are very difficult to find online. Packs of oral jelly will range from roughly $75 for twenty packets to over $300 for one hundred. Single-dose packets of jelly that will cost anywhere from $1 to $4.


If you are considering using sildenafil to treat your erectile dysfunction, always speak to your doctor first. Reputable pharmacies will only sell sildenafil citrate products to patients with prescriptions.

There are many shady online pharmacy sites that will claim to sell you sildenafil without a prescription. Buyer beware: these sites will often sell you an inferior product, or simply take your money and never deliver a product at all. Speaking to your doctor first will also greatly reduce the odds that you’ll buy a medication you’ll have an adverse reaction to.

Sildenafil citrate products are popular treatments for erectile dysfunction, thanks to their ability to increase blood flow to the penis. These products are available in a variety of forms to be taken orally, and at a large range of prices. Speak with your PCP to see which sildenafil product is right for you.
