What Is Avanafil and How Does It Work for Young Men?

Avanafil is a phosphodiesterase type 5 (PDE5) inhibitor, the same class of medicine as sildenafil (Viagra), tadalafil (Cialis) and vardenafil (Levitra). It works by relaxing the blood vessels in the penis, allowing increased blood flow when you are sexually aroused [6]. Importantly, avanafil does not cause an automatic erection; sexual stimulation is still required for the medicine to work.

For young men, avanafil can be particularly appealing because of its rapid onset. Clinical trials show that avanafil can start working within 15 to 30 minutes of taking it, which is faster than most other PDE5 inhibitors [11]. This makes it a flexible option for spontaneous intimacy. Avanafil is available in 50mg, 100mg and 200mg tablets, with the usual starting dose being 100mg taken about 30 minutes before sexual activity [6].

It is important to understand that avanafil treats the physical symptoms of ED but does not address underlying causes. Young men experiencing ED should consider seeing their GP, as erectile difficulties can sometimes signal early cardiovascular issues, diabetes, hormonal imbalances, or psychological factors such as anxiety or stress [1][2]. Avanafil can help restore confidence and function while these underlying issues are explored and managed.

Is Avanafil Safe and Effective for Younger Men?

Yes, avanafil is licensed for use in men aged 18 and over, and clinical studies have demonstrated its effectiveness across a broad age range, including younger adults [6][11]. In clinical trials, avanafil significantly improved erectile function compared to placebo, with many men reporting successful intercourse within 15 minutes of taking the medicine [11]. The safety profile of avanafil in younger men is similar to that in older age groups, though younger men may experience fewer age-related health conditions that complicate treatment.

Common side effects of avanafil include headache, flushing, nasal congestion and back pain, which are generally mild and short-lived [6]. Serious side effects are rare but can include sudden vision or hearing loss, chest pain during sex, or an erection lasting more than four hours (priapism), all of which require urgent medical attention. Younger men are often healthier overall, but it is still essential to disclose all current medicines and health conditions during your consultation, as avanafil can interact with certain drugs, particularly nitrates, alpha-blockers and potent CYP3A4 inhibitors [6].

Avanafil should not be taken if you use nitrates (such as GTN spray or isosorbide mononitrate), nicorandil, riociguat, or recreational drugs known as 'poppers' (amyl or alkyl nitrites), as the combination can cause a dangerous drop in blood pressure [6]. If you take alpha-blockers for prostate or blood pressure issues, your prescriber will need to assess whether avanafil is safe and may start you on a lower dose. Always be honest about your medical history and current medications during your online consultation.

Who Should Not Take Avanafil?

Avanafil is not suitable for everyone. You should not take avanafil if you have been advised that sexual activity is inadvisable due to heart problems (such as recent heart attack or stroke, unstable angina, or severe heart failure), if you have very low blood pressure, or if you have a history of non-arteritic anterior ischaemic optic neuropathy (NAION), a rare form of sudden vision loss [6]. Men with certain inherited retinal disorders should also avoid PDE5 inhibitors. Your prescriber will review your medical history during the consultation to ensure avanafil is safe for you.

When to get urgent help

• An erection lasting more than 4 hours (priapism)—go to A&E immediately
• Sudden loss of vision or hearing—stop taking avanafil and seek urgent medical help
• Chest pain during or after sex—call 999 and do not take further doses
• Severe allergic reaction (swelling of face, lips or throat, difficulty breathing)—call 999
• Severe dizziness or fainting after taking avanafil—seek same-day medical advice

Call 999 or go to A&E in an emergency, or contact NHS 111 for urgent advice.

How Does Avanafil for Young Men Compare to Other ED Treatments?

When choosing an ED treatment, young men often weigh up speed of action, duration of effect, side effects and cost. Avanafil's key advantage is its rapid onset—it can work in as little as 15 to 30 minutes, faster than sildenafil (about 1 hour), tadalafil (at least 30 minutes) or vardenafil (25–60 minutes) [6][3][4][5]. This makes avanafil ideal if you value spontaneity and do not want to plan too far ahead.

However, avanafil's effect lasts for around 4 to 6 hours, which is shorter than tadalafil's up-to-36-hour window [4][6]. If you prefer a longer duration of action or the option of daily low-dose treatment, tadalafil may be more suitable. Sildenafil and vardenafil sit somewhere in between, with effects lasting around 4 to 5 hours [3][5]. All four medicines require sexual stimulation to work and should be taken no more than once in 24 hours.

Cost is another consideration. Avanafil (Spedra) tends to be more expensive than generic sildenafil or tadalafil, though it is still affordable for many men. At Cured Pharmacy, Spedra (avanafil) is priced at £20.95, or £16.76 for your first order with code Ednew. Generic sildenafil starts from as little as £0.45 (£0.36 with code Ednew), while tadalafil is £7.95 (£6.36 with code Ednew). Your choice will depend on your priorities: speed, duration, side effects and budget. All these medicines are available after an online consultation reviewed by a UK prescriber.

Common Causes of Erectile Dysfunction in Young Men

Erectile dysfunction in younger men is less common than in older age groups, but it is far from rare. Studies suggest that psychological factors—such as performance anxiety, stress, depression, or relationship difficulties—play a significant role in ED among men under 40 [1][2]. These issues can create a cycle of worry that makes erections harder to achieve, even when physical health is otherwise good.

Physical causes can also contribute. Lifestyle factors such as heavy alcohol use, smoking, recreational drug use (especially cocaine and cannabis), lack of exercise, poor diet and obesity are all linked to erectile difficulties [1][2]. Underlying health conditions, including diabetes, high blood pressure, high cholesterol and hormonal imbalances (such as low testosterone), can affect erectile function even in younger men. In some cases, ED can be an early warning sign of cardiovascular disease, so it is important to see your GP for a full assessment [1][2].

Certain prescription medicines can also cause or worsen ED, including some antidepressants, blood pressure tablets and antipsychotics. If you suspect your medication is affecting your erections, speak to your doctor—never stop a prescribed medicine without advice. Addressing the underlying cause, whether physical or psychological, is an important part of managing ED. Avanafil and other PDE5 inhibitors can help restore function and confidence while you work on these factors with your healthcare team.

When to See Your GP About Erectile Dysfunction

If you are a young man experiencing persistent erectile difficulties, it is a good idea to see your GP, even if you feel embarrassed. Your doctor can check for underlying health conditions, review your medications, and discuss lifestyle changes that may help [1][2]. ED can sometimes be the first sign of cardiovascular disease or diabetes, so early assessment is important. Your GP can also refer you for specialist support if needed, including counselling or psychosexual therapy if psychological factors are contributing. Online ED services, like those at Cured Pharmacy, are convenient and discreet, but they work best alongside—not instead of—a full medical review.

How to Take Avanafil Safely and Get the Best Results

Avanafil is taken as needed, approximately 15 to 30 minutes before you plan to have sex. The usual starting dose is 100mg, though your prescriber may adjust this to 50mg or 200mg depending on your response and any side effects [6]. Swallow the tablet whole with water; you can take it with or without food, although a very heavy or high-fat meal may delay its effect slightly. Do not take more than one dose in 24 hours, and remember that sexual stimulation is required for avanafil to work—it will not cause an automatic erection.

To get the best results, try to relax and avoid excessive alcohol, as heavy drinking can make it harder to achieve an erection and increases the risk of side effects such as dizziness [6]. Avoid grapefruit juice, as it can raise avanafil levels in your blood and increase the chance of side effects. If avanafil does not work the first time, do not be discouraged—it can take a few attempts to find the right dose and timing. Speak to your prescriber if you have concerns or if the medicine is not effective after several tries.

Store avanafil at room temperature, away from moisture and direct sunlight, and keep it out of reach of children. Never share your medicine with others, even if they have similar symptoms. If you experience side effects such as severe headache, chest pain, sudden vision or hearing loss, or an erection lasting more than four hours, seek urgent medical help. For less serious side effects, such as mild headache or flushing, these usually settle on their own. If they persist or bother you, discuss them with your prescriber—they may be able to adjust your dose or suggest an alternative treatment.
