Erectile dysfunction refers to difficulty developing or maintaining an erection. It is a common condition, affecting at least 52% of American males between the ages of 40 and 70.

Different medical and psychological conditions can work together or independently to cause ED, and the American Urological Association (AUA) has clear treatment guidelines for the condition.

This article looks at various treatment options for ED, including OTC supplements, natural remedies, and prescription medications. We also discuss the evidence and risks associated with these options.

Is there an over-the-counter Viagra?

Sildenafil is the generic name for Viagra. This medication is only available via prescription in the United States (US). Therefore, viagra is not available OTC.

An OTC Viagra alternative refers to any supplement or herb that claims to produce similar effects to Viagra.

In most cases, there is insufficient research to suggest that OTC Viagra alternatives can benefit sexual function.

The US Food and Drug Administration (FDA) does not regulate OTC Viagra alternatives for their safety or effectiveness. Moreover, the FDA cannot test all products marketed for use as sexual enhancers.

Over-the-counter Viagra alternatives are a type of supplement, and the FDA does not regulate supplements for their safety or effectiveness. Supplements may contain a combination of ingredients, or product labels may not specify which ingredients the product contains. As such, the FDA does not recommend using OTC products for ED.

Since OTC Viagra alternatives are not FDA-regulated, manufacturers are not legally allowed to state that their products treat ED. Instead, they may market products as sexual enhancers with the aim of helping people achieve or maintain an erection.

What are the options for over-the-counter viagra?

Dehydroepiandrosterone

Dehydroepiandrosterone (DHEA) is an important hormone for sexual function. It helps create sex hormones, including testosterone and estrogen.

The adrenal gland naturally produces DHEA. However, DHEA levels in the body peak in a person’s 20s, then gradually decrease with age.

According to a 2018 review, evidence suggests that low levels of DHEA in the body can increase the chance of ED. However, studies have not conclusively shown that DHEA supplements can treat ED or improve sexual performance.

DHEA manufacturers also claim their supplements can boost energy, enhance immunity, and slow aging. However, there is not enough evidence to suggest that DHEA has any of these effects.

One significant drawback of DHEA is that it is not suitable for athletes. The United States Anti Doping Agency (USADA) prohibits the use of DHEA in sports, and notes that the substance falls under the category of anabolic agents on the World Anti-Doping Agency Prohibited List.

Another drawback of DHEA is the lack of studies investigating its safety, effectiveness, and dosages.

Since DHEA is readily available as a supplement, the premise is that people who take it do so for the long term. Unlike Viagra, any potential results build up over time rather than producing an immediate erection or sexual benefit.

Best DHEA: Spring Valley DHEA Tablets

• List price: around $16
• Type: tablets
• Supply: 50-day supply

Spring Valley provides a DHEA supplement in tablet form. One bottle contains 50 tablets, and the label states that a person should take one daily.

Each tablet contains 50 milligrams (mg) of DHEA.

Spring Valley says its product is non-GMO and does not contain gluten or dairy.

L-arginine

L-arginine is a common amino acid in men’s health supplements.

The body converts L-arginine into the chemical “nitric oxide”. This chemical may help the blood vessels open wider, thereby improving blood flow throughout the body.

Research from 2021 found a link between L-arginine deficiency and ED. The authors noted that combining L-arginine with a prescription ED treatment such as tadalafil may improve ED. However, a person should talk to their doctor before combining supplements and medications, as doing so can cause adverse effects.

A 2022 review notes that L-arginine in doses of 1,500–5,000 milligrams (mg) shows some effectiveness in treating mild to moderate ED.

Additionally, a 2020 small-scale clinical trial reported that taking 2,500 mg of L-arginine alongside improved symptoms of mild to moderate ED.

However, a person should be cautious when taking L-arginine or similar supplements, as side effects can include:

• nausea
• diarrhea
• slightly lower blood pressure

As with other supplements, any benefits of taking L-arginine are likely to arise from continuous use. However, scientists currently do not know how safe it is to take high dose L-arginine supplements for more than 3 months.

Best L-arginine: Horbäach L-Arginine

• List price: around $19
• Type: caplets
• Supply: 30-day supply

Hornaach L-arginine offers L-arginine caplets. One bottle contains 120 caplets, and the label states that a person should take 4 caplets daily.

Each caplet contains 1,000 mg of L-arginine.

According to Horbaach, its formulation is free of additives and potential allergens, including:

• gluten
• wheat
• lactose
• soy

Ginseng

Ginseng or “Panax ginseng” is a popular herbal remedy that is available in the form of pills and creams. Manufacturers claim that it can help with fertility and improve sexual function.

Ginseng contains chemicals called ginsenosides. One action of these chemicals is to promote nitric oxide, which may help trigger an erection by relaxing the smooth muscles in and around the penis.

A 2021 review found that ginseng has a trivial effect on ED in comparison to placebos. However, more research is necessary.

The National Center for Complementary and Integrative Health (NCCIH), notes that the most common side effect of ginseng is interrupted sleep or insomnia.

According to the NCCIH, other potential side effects include:

• headaches
• breast pain
• issues with menstruation
• fast heart rate
• changes in blood pressure
• digestive issues

It is important that a person talks to their doctor before taking ginseng, since this supplement can interact with a variety of medications, including:

• calcium channel blockers
• statins
• certain antidepressants

Best ginseng: Mason Natural Korean Ginseng

• List price: around $9
• Type: tablets
• Supply: 60-day supply

Mason Natural offers a ginseng supplement in tablet form. Each bottle contains 60 tablets, and the label recommends that a person take one tablet daily.

Each tablet contains 1,000 mg of ginseng.

According to Mason Natural, its product is soy free and contains minimal inactive ingredients.

Propionyl-L-carnitine

Propionyl-L-carnitine is one of the commercially available forms of L-carnitine. This chemical plays an essential role in metabolism and in helping protect the body from certain forms of free radical damage.

A 2021 systematic review states that antioxidants such as propionyl-L-carnitine may increase the effectiveness of ED medications such as tadalafil. However, further research is necessary.

It is also not clear whether propionyl-L-carnitine alone would have the same beneficial effects on ED.

Scientists also have not established safe and effective dosages for propionyl-L-carnitine.

Best propionyl-L-carnitine: Swanson Propionyl L-Carnitine with Glycine

• List price: around $52
• Type: vegetarian capsules
• Supply: 30 or 60-day supply

Swanson sells a propionyl-L-carnitine and glycine supplement containing 60 vegetarian capsules. The product label recommends that individuals take one capsule once or twice daily with water.

Each capsule contains 515 mg of propionyl-L-carnitine and 150 mg of glycine.

This product is available in a multipack of two.

Yohimbe

Yohimbe is an African evergreen tree. Its bark contains a compound called yohimbine, which has traditional uses as an aphrodisiac.

According to the NCCIH, people also use yohimbe as a natural supplement for ED and other issues, including:

• weight loss
• high blood pressure
• diabetes-related nerve damage

However, a 2022 review refers to studies in which participants took yohimbine as a treatment for ED. These studies found that yohimbine was no more effective at controlling ED than a placebo.

The NCCIH states that there is not enough evidence to support the use of yohimbe for ED or any other medical condition.

The NCCIH also notes the possible side effects of yohimbe, which include:

• digestive issues
• increased blood pressure
• a fast or irregular heartbeat
• anxiety

Yohimbe has also been associated with heart attacks and seizures.

The NCCIH states that yohimbe can interact with certain medications, including a class of antidepressant medications called monoamine oxidase inhibitors (MOAs).

A person should speak with a doctor before taking yohimbe.

OTC Viagra comparison

The table below compares all of the above OTC Viagra alternatives.

How does over-the-counter Viagra work?

Over-the-counter products marketed for ED claim to benefit those with ED, either by increasing levels of certain sex hormones, or by widening blood vessels to facilitate an erection.

However, there is currently no evidence to suggest that OTC Viagra is safe or effective. A person should exercise caution before trying any OTC Viagra products and speak with a doctor before making a purchase.

Is over-the-counter viagra for ED safe?

The FDA does not test or regulate OTC Viagra alternatives, and there is insufficient research to determine whether these supplements are safe or effective.

The FDA recommends being particularly cautious with ED pills that:

• claim to produce fast results, such as within 30–40 minutes
• are available in single servings
• are labeled as alternatives to prescription drugs
• are marketed through unsolicited emails
• have labels in a different language without trusted translation
• contain warnings and directions that mimic those of prescription products

In addition, the FDA has a database of over 300 products marketed for ED that contain excessively high doses or undisclosed ingredients. These ingredients may interact with other medications a person is taking, potentially resulting in harmful consequences.

For example, these products may interact with drugs that contain nitrates, such as:

• nitroglycerin, which helps treat angina and coronary heart disease
• isosorbide or nitroprusside, which helps treat high blood pressure
• amyl nitrate, which helps treat angina

Given the above, it is best to speak with a doctor before taking any supplement.

What are the risks of OTC treatments for ED?

Potential risks of using OTC treatments for ED include:

• Drug interactions: Some supplements may cause unsafe interactions with other medications or supplements that an individual is taking.
• Undisclosed ingredients: Inaccurate reporting of ingredients could lead to a person consuming harmful ingredients or consuming a harmful dose of ingredients.
• Quality control: A lack of quality control and FDA regulation can lead to dangerously different levels of active ingredients in the same product.

Prescription drugs for ED

A doctor may prescribe medications that stimulate blood flow to the penis, thereby causing an erection.

These drugs are known as PDE-5 inhibitors. They extend the effects of nitric oxide, which the body produces to relax muscles and increase blood flow.

The four main FDA-approved oral drugs for ED are:

• Sildenafil (Viagra): Individuals typically take sildenafil around 1 hour before sex, up to once daily. Hims offers generic sildenafil at around $3 per dose. Branded Viagra starts from $139 per dose.
• Avanafil (Stendra): Individuals taking avanafil in doses of 100 mg or 200 mg should take the medication up to 15 minutes before sex, whereas those taking a 50 mg dose should take the medication around 30 minutes before sex. In both cases, a person should not take more than one dose in a 24-hour period. This product is unsuitable for smaller budgets, with six tablets costing $414.33 at Blink Health.
• Tadalafil (Cialis): Depending on the doctor’s instructions, individuals can take tadalafil daily, or as they need around 30 minutes before sex. However, they should not exceed more than one dose within a 24-hour period. Hims offers a generic version for around $82 per month.
• Vardenafil (Levitra): Individuals can take vardenafil around 60 minutes before sexual activity, and should not exceed more than one dose per day. The generic version of vardenafil costs around $126 for six tablets at Blink Health.

Side effects

Different drugs vary in dose, how long they work, and possible side effects. Roughly 40% of those who take PDE-5 inhibitors for ED experience side effects, although these symptoms are usually mild.

Below is a table featuring the four main PDE-5 inhibitors and some of their more common side effects.

Interactions

Sildenafil, the active ingredient in Viagra, can interact with medications for the following conditions:

• high blood pressure
• high cholesterol
• diabetes
• heart disease

People with any of the above conditions should consult a doctor before taking ED medications or supplements, whether prescription or OTC.

Medications for ED may also not be suitable for people with certain underlying medical conditions, including:

• heart problems
• very low blood pressure or uncontrolled high blood pressure
• liver disease
• kidney disease

A person’s doctor can determine which medication is the best fit for them.

Alternatives to OTC Viagra

There are several other treatment options for ED. These include vacuum devices and ED rings.

Vaccum devices are mechanical pumps that create an erection by drawing blood into the penis. Around 77% of people who use vacuum devices or penis pumps for ED were satisfied with the results.

ED rings are bands that go around the base of the penis to help maintain an erection. A 2022 case report states that ED rings can be effective in improving ED.

Learn more about the various treatment options for ED here.

However, there are some risks involved with penis pumps and rings, including:

• bruising
• pain, including painful erections
• numbness and tingling
• burst blood vessels

A person should always speak with a doctor before trying a new ED treatment to ensure it is safe.

Natural options

Certain lifestyle factors can increase a person’s chance of erectile problems. Controlling these factors may help improve their symptoms.

The following may help naturally treat erectile problems and boost the person’s overall health:

• not smoking
• exercising regularly
• maintaining a moderate weight
• eating a healthy diet
• reducing stress or anxiety

Contacting a doctor

Prescription medications can help people manage ED symptoms, but they require a consultation with a physician. Research reports that males are less likely than females to seek preventive or immediate medical care.

As an alternative, some businesses offer telehealth services that include ED diagnostic and treatment options. The ability to access evaluation and treatment online can help people save money, time, and preserve anonymity, which may make it more likely that they can get the safe and professional help they need.

Learn more about the benefits of telemedicine.

However, telehealth should not replace in-person exams since ED can be associated with other health issues, such as cardiovascular disease.

Frequently asked questions about OTC Viagra

Here are some of the most commonly asked questions about Viagra and OTC alternatives for erectile dysfunction.

Are there over-the-counter pills that work like Viagra?

According to the National Center for Complementary and Integrative Health (NCCIH), there are no safe and effective alternative treatments for ED. Some OTC treatments may contain active ingredients found in prescription drugs, but not at safe levels. They may also contain other unapproved drugs with unknown and potentially dangerous effects.

How can I get ED treatment without seeing a doctor?

Prescription medications, such as Viagra, are a widely effective way to treat ED, but it is not possible to obtain prescription drugs without consulting a doctor. 

Telehealth makes it possible for people to consult with doctors and receive prescriptions for ED medications from the privacy of their homes. Telehealth can also help people save time and money and avoid feeling potentially uncomfortable.

What is the best over-the-counter ED treatment?

Lifestyle measures are typically the first step in treating ED. These may be the best approach to treating the condition since the NCCIH reports that there are no safe and effective alternative treatments for ED. 

These lifestyle changes may include:

• not smoking
• increasing physical activity
• eating a healthy diet
• moderating alcohol use
• managing chronic conditions such as diabetes and high cholesterol

How do I talk with my partner about erectile dysfunction?

Both people with ED and their partners may wish to talk about the condition and how it is affecting their sexual and romantic life.

It is important that people choose a moment that is not stressful and allows for time to properly discuss the condition, such as during a walk or a quiet time at home.

ED is common, especially in males over 40 years of age. However, this condition is treatable. People should discuss contacting a healthcare professional for treatment. Lifestyle changes, such as increasing physical activity, limiting alcohol consumption, and quitting smoking can also improve symptoms.

Some people may find couples or individual therapy beneficial. Therapists can help people navigate any negative feelings toward themselves or their partners and can encourage healthy and constructive communication.

Am I too young to take Viagra?

While the risk of ED increases as a person ages, it is possible for younger people to have this condition. Researchers from a 2021 study asked a large sample of sexually active US males aged between 18-31 how ED has affected them. 11.3% of these males reported mild ED, whereas 2.9% reported moderate to severe ED.

Viagra is suitable for people who are 18 years of age and older. People of any age who believe they may have ED should contact a healthcare professional to discuss possible lifestyle changes and treatment.

Summary

Prescription medications may be an effective treatment for ED, although they are not safe for everyone. Telehealth options make it more convenient and private for people to access the medical consultations they need to obtain prescription ED drugs.

To date, research has not confirmed any OTC pills or supplements that safely or effectively treat ED, but prescriptions and supplements are not the only ways to address this condition. Individuals with questions about ED treatment should discuss options with their physicians.
