Spedra

What is Spedra?

Spedra (avanafil) is the newest erectile dysfunction medication in the PDE-5 inhibitor class. The active ingredient in Spedra, avanafil, was specifically developed to offer two key advantages: the fastest onset of action and exceptionally high selectivity, making it a popular choice for men looking to buy Spedra online.

The fastest onset of action: Unlike older medications that take 30–60 minutes, Spedra can start working in as little as 15-30 minutes—and some users report improvements from about 12 minutes. This makes it ideal for men seeking increased spontaneity.

High selectivity and good tolerability: Avanafil was developed to be highly selective for the PDE-5 enzyme in the penis. This means less impact on other phosphodiesterases in the body and potentially fewer side effects from Spedra compared to older PDE-5 inhibitors.

Balanced duration of action: Spedra’s effect lasts up to 6 hours, long enough for natural flexibility without the prolonged action of medicines like Cialis.

How effective is Spedra?

Clinical trials show that Spedra is effective for most men when used correctly. In the pivotal Phase III study, 59% of men taking the 200 mg dose were able to successfully complete intercourse, compared to just 28% of those taking a placebo — more than doubling the success rate. [1]

Even in harder-to-treat groups, such as men with type 2 diabetes, avanafil produced meaningful improvements, with success rates of up to 45% compared to 16% for the placebo group. [2]

Spedra also stands out for its speed: it is the fastest-acting licensed erectile dysfunction treatment available, with measurable effects as early as 15 minutes after taking the tablet — though most men achieve the most reliable result by waiting 30 minutes. [3]

How does Spedra work for erectile dysfunction treatment?

Spedra belongs to the PDE-5 inhibitor class. Its active ingredient, avanafil, blocks the PDE-5 enzyme that breaks down cGMP, a messenger responsible for relaxing blood vessel walls in the penis.

During sexual stimulation, nitric oxide increases cGMP production. By inhibiting PDE-5, Spedra helps cGMP remain active longer, allowing better blood flow into the erectile tissue and supporting firmer erections.

Important: Spedra tablets (as well as other ED medications) only work with sexual stimulation and do not increase libido.

Is Spedra available without a prescription?

No, Spedra is a prescription medication. It is not legal to buy avanafil tablets without a prescription. A doctor's assessment ensures that the medication is suitable for you, that there are no dangerous interactions, and that the dosage is correct. This also applies if you wish to buy Spedra online.

Depending on your prescribed strength, you can buy Spedra 50 mg, buy Spedra 100 mg or buy Spedra 200 mg, allowing your doctor to tailor the treatment to your individual response and level of erectile dysfunction.

Who is Spedra suitable for?

Spedra tablets are suitable for adult males with erectile dysfunction who value rapid onset of action and spontaneity. It is particularly advantageous to order Spedra for:

• Men who desire spontaneity: The rapid onset of action after 15-30 minutes allows for spontaneous sex without long waiting times.
• First-time users of ED meds: Spedra's good tolerability due to high selectivity makes it a good choice for men trying ED treatments for the first time.
• Patients with side effects from other erectile dysfunction medications: Men who have experienced bothersome side effects such as visual disturbances or nasal congestion with other PDE-5 inhibitors often tolerate Spedra better.
• Men with occasional erectile dysfunction: The duration of action of up to 6 hours is ideal for occasional use without an excessively long effect.

However, before ordering Spedra, you should always consult a doctor to determine whether:

• Cardiovascular diseases are present
• Other medications are being taken
• Severe liver or kidney disease exists
• An allergy to avanafil or other ingredients is present.

How to take Spedra correctly to treat erectile dysfunction?

Recommended dosage of Spedra:

The standard dose is 100 mg of avanafil approximately 15 to 30 minutes before sexual activity. Depending on effectiveness and tolerability, the dose may be adjusted by increasing to 200 mg or lowering to 50 mg. 

Important notes:

• Take Spedra tablets at most once a day
• A minimum interval of 24 hours between doses must be observed.
• Swallow the tablet whole with a glass of water.
• It can be taken regardless of meals.
• For optimal effectiveness of Spedra: Avoid very fatty meals immediately before taking it.
• When taken on an empty stomach: Fastest onset of action possible after 15 minutes.

When should Spedra not be taken?

You should not buy or take Spedra if you:

• are allergic to avanafil or any other ingredients in the medication
• are taking nitrates or nitric oxide donors (e.g. for angina pectoris)
• are taking guanylate cyclase stimulators such as riociguat
• are taking strong CYP3A4 inhibitors such as ketoconazole, itraconazole, ritonavir, indinavir, saquinavir, nelfinavir, atazanavir or clarithromycin
• have severe cardiovascular disease or recent stroke or heart attack (within the last 6 months)
• have uncontrolled high blood pressure or very low blood pressure (below 90/50 mm Hg)
• have severe liver failure (Child-Pugh class C)
• have severe renal impairment with creatinine clearance below 30 ml/min
• have previous vision loss due to non-arteritic anterior ischaemic optic neuropathy (NAION)
• have congenital degenerative retinal disorders

Spedra is not approved for women or persons under the age of 18.

Tell your doctor if you have an anatomical deformity of the penis, including Peyronie’s disease, as this may increase the risk of complications such as a prolonged or painful erection and should be considered before using Spedra.

Which medications are incompatible with Spedra?

Avoid combining Spedra with:

• Nitrates & NO-donors – dangerous drop in blood pressure
• Strong CYP3A4 inhibitors – significant increase in avanafil levels
• Moderate CYP3A4 inhibitors (e.g., erythromycin, grapefruit juice) – limit to max. Spedra 100 mg, 48-hour spacing
• Alpha-blockers – risk of hypotension unless stable on therapy
• Other erectile dysfunction medications – never mix PDE-5 inhibitors
• Excessive alcohol – can worsen dizziness/headache

Spedra vs. Viagra: what's the difference?

Spedra (avanafil) and Viagra (sildenafil) are both PDE5 inhibitors that work in the same way, increasing blood flow to the penis during sexual stimulation. They are both clinically proven to effectively treat erectile dysfunction. The main practical differences come down to speed and tolerability.

Spedra acts faster, with effects possible from around 30 minutes, compared to 45–60 minutes for Viagra. It also has a lower rate of visual side effects, such as the blue-tinge disturbance sometimes reported with sildenafil.

However, Viagra has over 25 years of real-world data behind it and is available in three dose strengths (25 mg, 50 mg and 100 mg). Generic sildenafil is also substantially cheaper than Spedra, which remains under patent. If cost is a factor and you are not in a hurry, buy Viagra or its generic version, as this is the more economical option. However, if speed of onset and tolerability are the priority, discuss Spedra with your prescriber.

Experiences with Spedra

Feedback from users of Spedra is consistently positive, particularly among men who have tried other erectile dysfunction treatments without achieving full satisfaction, especially those who found the timing demands of sildenafil inconvenient, or who experienced side effects such as flushing and visual disturbances.

The faster onset is the most frequently cited advantage in forum discussions and patient reviews; men describe being able to take the tablet and then engage in sexual activity naturally, without having to time it. In clinical trials, Spedra was also associated with lower discontinuation rates due to side effects than some other PDE5 inhibitors, which aligns with patient reports.

The most common complaints in user accounts are the price, as Spedra is significantly more expensive than generic sildenafil or tadalafil.

"...found that for me, Avanafil (Spedra) is extremely effective and reliable. Much faster onset (15/30 minutes) and zero side effects (no congestion, no blushing, no blue vision). It is however much more expensive, and I have no clue for how long it will remain effective for me."

As for tolerability, occasional headaches are the most frequently reported side effect across the PDE5 inhibitor class.

"I often get a 36-hr headache on Cialis, and a racing heartrate on Viagra. Stendra (edit. another brand name of Avanafil) is just a little stuffy nose and very mild headache, and then only sometimes. I started at 50mg which didn't seem to do much, and now take 100mg which works fine. The erections feel very 'natural'."

Spedra tends to earn loyal users among men who have not responded well to other treatments or who simply want a faster, cleaner experience. However, for those trying an ED medication for the first time, most prescribers still start with sildenafil or tadalafil, given the cost difference and the depth of long-term data behind both.

How much does Spedra cost in the UK?

Spedra is one of the pricier ED treatments available in the UK, largely because avanafil remains under patent and no generic equivalent is currently licensed. Prices vary by dose and pack size, but as a guide:

Pack size	Spedra 50 mg	Spedra 100 mg	Spedra 200 mg
4 tablets	£30–35	£35–40	£40–50
8 tablets	£55–65	£60–70	£70–85

Spedra prices are approximate.

For context, a single Spedra tablet typically costs around £8–12, compared to under £2 for generic sildenafil or tadalafil in similar pack sizes. The price premium reflects the novelty of the compound and the absence of generic competition — not a difference in how the drug works.
