Over the last 25 years, erectile dysfunction (ED) medications like Viagra® and Cialis® have become common fixtures in bedrooms around the world. These ED pills have helped hundreds of millions of men get hard and stay hard. But what are the best ED pills?

While pills like Viagra, Cialis, and Stendra® might look similar, they’re unique medications with their own strengths and weaknesses for dealing with erectile dysfunction.

This means there’s no one-size-fits-all solution. The best ED medication is the one that works for your symptoms and lifestyle.

Below, we’ll discuss how to choose the best ED pill for your needs by explaining how these sexual health medications work, the pros and cons of each, how long they last, and more.

Which drug is best for treating ED?

The most popular erectile dysfunction medications currently on the market are:

All of these ED pills belong to a class of drugs called phosphodiesterase type 5 inhibitors, or PDE5 inhibitors. They’re vasodilators, meaning they improve blood flow to the tissue inside your penis by widening blood vessels.

With improved blood flow, PDE5 inhibitors like Viagra and Cialis make it easier for your penis to become firm and enlarged in response to sexual stimulation — i.e., get an erection. It’s also easier to maintain an erection long enough to have satisfying sex.

These drugs are so effective that they’re typically recommended as first-line treatments for ED, regardless of whether ED symptoms are caused by psychological factors or physical ones.

The FDA (U.S. Food and Drug Administration) has approved all of these medications, and you’ll need a prescription to buy and use them as ED treatments.

Beware of Over-the-Counter ED Pills

If you’ve come across over-the-counter ED pills or supplements that claim to work fast, like Rhino® pills at the gas station, know they aren’t supported by solid scientific evidence. In fact, many are associated with serious safety risks.

So it’s best to avoid them.

We’ll profile the best ED treatments below to give you more insight into how FDA-approved prescription drugs work.

Choosing the best erection pills is a personal decision you make together with your healthcare provider. What might work for one guy may not work as well for another. It’s up to you and your provider to find a suitable plan for your needs.

Keep reading to compare the pros and cons of each prescription medication for ED.

Sildenafil (Viagra)

Sildenafil is the OG prescription medication for erectile dysfunction. It came onto the market in the late ‘90s under the brand name Viagra. For several years, it was the only medication available for men with ED.

Today, sildenafil is available in a generic version, meaning it’s much more affordable than when it first hit the pharmacy shelves. And it’s still among the best erectile dysfunction pills.

Why? Sildenafil works quickly, provides relief from ED for around four hours, and is sold in just about every pharmacy, making it a reliable option for improving sexual function.

  • Best for: Guys who want a dependable treatment option for ED with a long track record and a good price per tablet.

  • Advantages: Sildenafil starts working in less than an hour and provides relief from ED for about four hours per pill, making it great for a single night.

  • Disadvantages: Sildenafil takes longer to work after a large, high-fat meal and can’t be taken more than once a day, so it’s less than ideal for twice-a-day (or more) sex.

Sildenafil Pros

Sildenafil is a reliable choice for treating ED. It’s been around for decades, is affordable, readily available, and has lots of data backing it.

  • Sildenafil is approved by the FDA. In research published by the FDA, 63 to 82 percent of men with ED reported better erections after taking Viagra.

  • Sildenafil works. In a more recent study published in the International Journal of Clinical and Experimental Medicine, over 98 percent of men with ED who used sildenafil reported high levels of satisfaction.

  • Sildenafil lasts long enough to get the job done. A typical dose of sildenafil lasts roughly four hours. It’s a good option if you want an ED pill designed to last for one night of sexual activity.

  • Sildenafil has a good safety profile. The relatively short duration of sildenafil can also mean the side effects are short-lived.

  • Sildenafil is affordable. Finally, sildenafil is a good ED treatment from a cost perspective. If you stick to generic Viagra, each pill only costs a few dollars, so you won’t have to spend much to enjoy better sex.

Sildenafil Cons

Sildenafil is only active for about four hours, so you’ll need to take it close to the time you plan to have sex. This means you might have to plan ahead of time if you’re going out on a date and want to make sure it works its magic once you get home.

Also, you can only use sildenafil once every 24 hours. So this ED pill might not be the best option if you and your partner like to have sex more than once a day.

Sildenafil is affected by certain foods and could take longer to start working if you eat a fatty meal (like a cheeseburger and greasy fries) just before or after you take it.

It can also cause side effects, including:

  • Headaches

  • Flushing or rash

  • Dyspepsia (indigestion), upset stomach, or nausea

  • Nasal congestion

  • Back pain or muscle soreness

  • Changes in vision

  • Dizziness

But keep in mind most side effects of sildenafil can also develop with other ED medications. Consult your medical provider with any questions about this.

Tadalafil (Cialis)

Tadalafil is the active ingredient in Cialis, which the FDA approved as an ED medication in 2003. Nowadays, it’s available in its generic form and as a brand-name drug for use as needed or as a daily tablet.

Thanks to its very long duration of action — more on this below — tadalafil is sometimes referred to as the “weekend pill” for treating erectile dysfunction.

Like sildenafil, tadalafil has a long track record. It’s been researched extensively, so both its erectile effects and side effects are well-known.

  • Best for: Men who like a long-lasting pill to treat ED, allowing for more spontaneous sex or sex more than once a day.

  • Advantages: Tadalafil lasts longer than any other ED treatment, with one pill providing relief from ED for up to 36 hours. It can also be taken daily at a lower dosage.

  • Disadvantages: Tadalafil might last longer than needed for some men. Its long duration means side effects could last longer than with other ED pills.

Tadalafil Pros

Like sildenafil, tadalafil is a reliable choice for men with ED. It can be taken daily or as needed before sex.

  • Tadalafil has a long half-life. Tadalafil has a half-life of 17.5 hours — it remains active in the body for far longer than other ED medications. A single dose can improve blood flow to the penis and make it easier to get an erection for up to 36 hours.

  • Tadalafil is good for those who plan to have sex more than once a day. It’s an ideal choice if you want to have sex more than once a day — or only want to take one pill over the course of an entire weekend.

  • Tadalafil can be taken daily. Another advantage of tadalafil is that it’s also available as a daily-use medication. This version of tadalafil is ideal if you want to have sex spontaneously or prefer to take your ED tablet on a daily basis instead of as needed.

  • You don’t have to time your meals around tadalafil. You can also take tadalafil without regard to food, so there’s no need to avoid large meals or fatty foods (like with Viagra) before using this medication.

Tadalafil Cons

Tadalafil’s biggest strength is also its biggest weakness. Since it’s such a long-lasting drug, it may cause side effects in some men that continue for up to 36 hours.

If you’re prone to side effects from oral medication for ED, you might prefer to use a shorter-acting ED medication, like sildenafil, vardenafil, or Stendra.

A second disadvantage is the price of tadalafil. Tadalafil is slightly more expensive than sildenafil on a per-tablet basis, though this may be less of a concern if you have sex more than once per dose.

Vardenafil (Levitra and Staxyn)

The active ingredient in Levitra (vardenafil) was approved by the FDA in 2003. It’s similar to sildenafil but lasts longer — research suggests it provides better blood flow and stronger erections for five to seven hours per dose.

  • Best for: Men who want a slightly longer-lasting ED medication than sildenafil but don’t want the all-day effects of tadalafil.

  • Advantages: Vardenafil lasts longer than sildenafil and usually starts working faster.

  • Disadvantages: Vardenafil is typically more expensive than sildenafil. Like sildenafil, it can only be taken once a day.

Vardenafil Pros

Vardenafil has several pros, most of which are related to time.

  • Vardenafil lasts longer than sildenafil. First, it lasts slightly longer than sildenafil, meaning you have a little extra flexibility regarding when you take it prior to having sex.

  • Vardenafil may work well for those who plan to have sex more than once. This longer duration also means vardenafil could be a good choice if you like to have sex twice a night.

  • Vardenafil works quickly. Research suggests it kicks in less than 10 minutes after taking it in some men. (Still, it’s best to take it at least 30 minutes before sexual intercourse.)

Vardenafil Cons

Like sildenafil, vardenafil can only be used once daily. This means it may not be the best ED pill if you plan to have sex several times in a day with a break between rounds one and two — for example, once in the afternoon and once at night.

Vardenafil side effects are similar to other ED drugs. Common adverse effects of vardenafil include:

  • Headaches

  • Flushing

  • Indigestion or nausea

  • Sinusitis (sinus inflammation), nasal congestion, and other flu-like symptoms

  • Increased creatine kinase (CK) levels

  • Dizziness

  • Back pain

Vardenafil prices are usually higher than sildenafil on a per-dose basis. This could make it less appealing as an ED pill if you’re budget-conscious and only need relief from erectile dysfunction for a few hours at a time.

Stendra (Avanafil)

Stendra contains the active ingredient avanafil. It’s a newer ED medication that received FDA approval in 2012.

This PDE5 inhibitor is less likely to cause side effects than older medications and begins working faster. However, it’s only available under the brand name Stendra, with no generic version.

  • Best for: Guys who want a fast-acting ED pill that can be taken almost right before sex without having to worry about avoiding certain foods.

  • Advantages: Stendra acts quickly — often in as little as 15 minutes — and is less likely to cause side effects than ED pills that have been around longer.

  • Disadvantages: Stendra isn’t available as a generic medication because the manufacturer still has the patent, so it costs more per tablet than other ED drugs. Though side effects are less common, they can still occur.

Stendra Pros

As a second-generation PDE5 inhibitor, Stendra has several advantages over older drugs for treating erectile dysfunction.

  • Stendra works quickly. It’s designed for use 30 minutes before sex, although research suggests it can be effective at treating ED when taken 15 minutes before sexual activity.

  • Stendra is less likely to cause side effects. Since avanafil is more selective for PDE5 than older ED medications, it’s less likely to cause some side effects. If you’re prone to side effects from sildenafil, tadalafil, or vardenafil, switching to Stendra might be a helpful way to access the benefits of ED medication with a milder side effect profile.

Stendra Cons

The main disadvantage is Stendra’s cost. Since it’s a new ED treatment, it’s still under patent protection. This means there’s no generic form of avanafil yet (its active ingredient) available in the U.S.

Some of the most common side effects of avanafil include:

  • Headache

  • Flushing

  • Back pain

  • Nasal congestion and inflammation

Although certain side effects are less common and more mild with avanafil than with older medications for ED, they can — and often do — still occur.

Chewable ED Meds

If you’re looking for something a little different, Hims offers discreet chewable ED meds in the form of hard mints. These ED pills are personalized to match your specific symptoms and needs.

Hims Hard Mints are made with the same active ingredients found in Viagra and Cialis (sildenafil and tadalafil) and customized at different dosages. Unlike traditional ED tablets, they’re chewed instead of swallowed.

  • Best for: Guys looking for ED medication with a proven track record but in a newer, modernized format, and men who can’t swallow pills.

  • Advantages: They have the same proven ingredients found in popular ED drugs like Viagra and Cialis, but in chewable form. These chewable meds also have a fresh, wintergreen taste and discreet packaging you won’t mind carrying around.

  • Disadvantages: Chewable sildenafil and tadalafil have the same side effects as other PDE5 drugs.

Chewable ED Meds Pros

Hims Hard Mints are ED meds that offer a fresh take on old favorites.

  • Hard Mints contain the same active ingredients as Viagra and Cialis. They’re made with the same active ingredients as well-known drugs like Viagra and Cialis but are chewable and discreet.

  • Hard Mints can be taken daily or before sex. Like those popular prescription drugs, they can also be used as needed or daily, depending on your needs. But they taste better.

  • Hard Mints can be personalized. Chewable erectile dysfunction medications are compounded drugs, which means they can be customized and personalized to meet your specific needs at the dosage you require.

Chewable ED Meds Cons

As a compounded medication, chewable ED meds aren’t approved by the FDA. But they’re totally legal and made with the same active ingredients as Viagra and Cialis, which are FDA-approved drugs. They’re also made in FDA-regulated facilities.

Side effects can include:

  • Headaches

  • Flushing

  • Upset stomach

  • Back pain

  • Nasal congestion

If you experience side effects with sildenafil or tadalafil tablets, you might experience the same side effects with Hims Hard Mints.

Sildenafil, tadalafil, vardenafil, and Stendra are all safe and effective medications when used as prescribed.

However, all medications for ED have the potential to interact with other medications, including several prescription drugs for health conditions like hypertension (high blood pressure), heart disease, and kidney disease.

If you’re considering using any type of ED medication, you should be aware of these potential drug interactions:

  • Nitrates. When used with nitrates for chest pain (angina) or cardiovascular disease, ED medications can cause extremely low blood pressure (severe hypotension) that may be life-threatening. Nitrates include nitroglycerin and poppers used for recreational purposes.

  • Antihypertensives. Certain other medications used to treat high blood pressure, such as alpha-blockers, may interact with ED medications.

  • CYP3A4 inhibitors. Medications that inhibit the enzyme CYP3A4 — including some protease inhibitors, antifungals, and antibiotics — may cause interactions when used with ED pills.

Although very uncommon, ED medications may also cause priapism — prolonged, painful erections for longer than four hours that can damage the tissue of your penis. Seek medical help as soon as you can if you develop a persistent or painful erection.

Before you use any type of ED medication, talk to your provider about any medications you currently use, as well as any medical conditions you have.

Our guides to sildenafil interactions, tadalafil interactions, and avanafil side effects discuss these serious side effects and risks in more detail and explain how to use ED medication safely.

What’s the best ED medication? That depends. Since ED symptoms can differ from person to person and everyone’s needs are unique, there isn’t a “best” erectile dysfunction pill for every man.

Each sex pill offers a slightly different experience and benefits, from a longer duration of action to a reduced risk of side effects.

If you’re considering ED medication and don’t know which pill is the best treatment for you, keep the following in mind:

  • Sildenafil (Viagra) and vardenafil (Levitra) are short-acting. These “one-night” ED medications are both available as generics, making them affordable medications to try first.

  • Tadalafil (Cialis) is much longer-lasting. This is a good option if you prefer all-day relief from erectile dysfunction. Like sildenafil, it’s considered one of the best ED pills.

  • Stendra (avanafil) is newer. If you’re looking for the best medicine for erectile dysfunction with fewer side effects, this one comes close. It kicks in fast and doesn’t cause as many adverse reactions as older ED pills, but it does cost more per tablet.

  • Chewable ED meds are a fresh way to treat ED. Hims Hard Mints contain the same active ingredients as drugs like Viagra and Cialis. They can be taken as needed or daily. Plus, they come in discreet packaging and are personalized to meet your exact needs.

  • Other treatments are available. We consider these drugs to be among the top ED pills, but there are many other ways to treat erectile dysfunction, depending on what’s causing it, including alprostadil injections, penile implants, and medication for low testosterone. Therapy for mental health issues may also help ED, as well as lifestyle changes to support sexual health, like following a healthy diet, exercising, and cutting back on alcohol.

Above all, you’ll want to provide your healthcare provider with as much information as possible about your symptoms. And closely follow their medical advice to get the best results from any ED medication.

When used right, ED pills can do more than just give you firmer erections — they can also boost your self-confidence in bed.
