Spedra 200 mg: What Is Avanafil 200mg and How Does It Work?

Spedra 200mg is the highest authorised tablet strength of the erectile dysfunction medicine avanafil. Each Spedra 200mg tablet contains 200mg of avanafil, a phosphodiesterase type 5 (PDE5) inhibitor used to treat erectile dysfunction (ED) in adult men. For adult men in the UK looking into Spedra 200mg as an ED treatment option, understanding when this strength is used and whether it is appropriate matters for both safety and effectiveness.

Although Spedra 200mg is an authorised strength, it is important to understand that 200mg is not the usual starting dose. The recommended starting dose is 100mg taken when required approximately 15 to 30 minutes before anticipated activity. Depending on individual effectiveness and tolerability, the dose can be increased to a maximum of 200mg or reduced to 50mg. Spedra should normally be taken no more than once per day.

Spedra does not automatically produce an erection. Avanafil supports the normal erectile response by increasing blood flow when appropriate stimulation occurs, and stimulation is required for the medicine to work.

This guide explains what Spedra 200mg is, when the higher dose may be considered, whether 200mg works better than 100mg, how quickly it can work, how food and alcohol can affect avanafil 200mg, the important side effects, safety considerations and contraindications, and what to do if the medicine does not work as expected.

What Is Spedra 200mg?

Spedra 200mg is a tablet containing 200mg of avanafil. It is used for erectile dysfunction in adult men. The tablet is described in European product information as a pale yellow oval tablet marked "200" on one side.

Avanafil belongs to the PDE5-inhibitor class of medicines. Spedra tablets are designed to target PDE5 selectively, which may help reduce side effects compared with older options. It works on the chemical pathway involved in increasing blood flow into erectile tissue during stimulation. It only works with sexual stimulation and does not increase duration.

The 200mg tablet represents the maximum recommended avanafil dose in the standard dosing schedule. It is generally considered when the usual 100mg dose has not produced an adequate effect and a higher dose is suitable for the individual patient.

What Is Spedra 200mg Used For in Erectile Dysfunction?

Spedra 200mg is used to treat erectile dysfunction, which involves difficulty getting or maintaining an erection. Avanafil improves the physiological response that allows increased blood flow into the penis.

It does not cure the underlying cause of ED. A person may still have a vascular, metabolic, neurological, hormonal, medicine-related or psychological contributor to erectile dysfunction even when avanafil successfully improves erections. The authorised product information therefore advises assessing the underlying causes of ED before medicine treatment is started.

Spedra should also not be used simply to enhance erections in someone who does not have erectile dysfunction.

Is the Active Ingredient in Spedra 200mg the Same as Avanafil 200mg?

Yes. Avanafil is the active ingredient in Spedra.

A Spedra 200mg tablet contains exactly 200mg of avanafil.

Therefore, searches such as:

• Spedra 200mg avanafil
• Spedra avanafil 200mg
• avanafil Spedra 200
• avanafil Spedra 200mg

all refer to the same medicine strength.

The distinction is simply that Spedra is the medicine name and avanafil is its active ingredient.

Is Spedra 200mg the Normal Starting Dose?

No.

The normal recommended dose is 100mg, taken when required approximately 15 to 30 minutes before anticipated activity.

The authorised dosing guidance allows the 100mg dose to be:

increased to 200mg when effectiveness is inadequate and the higher dose is tolerated, or

reduced to 50mg when a lower dose is more appropriate.

The patient leaflet similarly explains that someone may be prescribed a 200mg tablet when their doctor determines that the 100mg dose is too weak for them.

This makes Spedra 200mg a dose-escalation option rather than the routine first dose.

When Might Spedra 200mg Be Prescribed?

A 200mg dose may be considered when 100mg has not provided an adequate response and the patient has tolerated avanafil sufficiently well. Dose decisions are based on individual effectiveness and tolerability.

Before increasing the dose, it is also useful to consider whether apparent treatment failure could be explained by how the tablet was taken.

For example, response may be affected by:

• Taking the tablet too close to anticipated activity
• Eating a substantial meal that delays absorption
• Insufficient stimulation
• Excessive alcohol
• An underlying cause of ED that reduces treatment response

Food is specifically recognised in the authorised information as potentially delaying Spedra's onset.

Increasing to 200mg should therefore not simply be viewed as the automatic solution whenever one 100mg tablet appears ineffective.

Is Spedra 200mg Stronger Than 100mg and What Are the Side Effects of Spedra?

Yes in terms of the amount of active ingredient: 200mg contains twice as much avanafil as 100mg, and 200mg tablets are the highest dose option rather than something every patient will need.

However, twice the dose does not mean twice the clinical effect.

This is particularly clear in the clinical-trial data.

Among the general ED study population, the average proportion of attempts resulting in successful intercourse was approximately:

• 58% with avanafil 100mg
• 59% with avanafil 200mg
• 28% with placebo

Among ED medications, Spedra is a newer option than Viagra, so comparisons are often made against Viagra's longer-established profile.

In broad terms, Spedra is effective for about 60% of men, while Viagra is often cited as effective for about 80% of men.

Viagra typically takes about 60 minutes to work, whereas Spedra's effects last around 4-5 hours, similar to Viagra.

These figures do not mean that 100mg and 200mg will work identically for every individual. Some patients can benefit from increasing the dose.

They do show why it would be inaccurate to say that Spedra 200mg is automatically twice as effective as Spedra 100mg.

Does Spedra 200mg Work Better Than 100mg?

It may work better for some individual patients, which is why increasing the dose to 200mg is authorised when response to 100mg is inadequate.

Across the overall trial population, however, the difference between 100mg and 200mg was relatively small for the proportion of attempts resulting in successful intercourse: approximately 58% versus 59%.

In men with diabetes and ED, the corresponding averages were approximately 34% with 100mg and 40% with 200mg, compared with around 21% for placebo.

Among men with ED following bilateral nerve-sparing radical prostate surgery, successful attempts averaged approximately 23% with 100mg and 26% with 200mg, compared with roughly 9% with placebo.

Individual response therefore matters more than assuming the highest dose is always the best dose.

How Does Spedra 200mg Work?

Avanafil is a selective inhibitor of the enzyme phosphodiesterase type 5 (PDE5).

During stimulation, nitric oxide is released and increases levels of cyclic guanosine monophosphate, or cGMP. Increased cGMP relaxes smooth muscle in erectile tissue and allows greater blood flow into the penis.

PDE5 breaks down cGMP.

Avanafil blocks PDE5, allowing the cGMP pathway to remain active and thereby supporting the erection response.

Crucially, avanafil has no erectile effect in the absence of stimulation or sexual activity.

How Quickly Does Spedra 200mg Work?

Spedra 200mg is generally taken approximately 15 to 30 minutes before anticipated activity.

One tablet is typically taken 15 to 30 minutes before anticipated activity.

Avanafil is absorbed relatively quickly. Under fasting conditions, maximum blood concentrations are generally reached within about 30 to 45 minutes.

There is also clinical evidence of an earlier response in some men.

In one study, avanafil 200mg produced erections considered adequate in some participants from around 20 minutes after dosing.

In a separate time-to-onset trial, approximately 28.18% of attempts with 200mg resulted in successful intercourse at around 15 minutes, compared with approximately 24.71% with 100mg and 13.78% with placebo.

These trial figures should not be interpreted as a promise that every user will respond within 15 or 20 minutes.

Should You Take Spedra 200mg Exactly 15 Minutes Beforehand?

Not necessarily.

The authorised guidance provides a window of approximately 15 to 30 minutes for the 100mg and 200mg strengths.

Individual onset can vary according to:

• Food intake
• Absorption
• Stimulation
• ED severity
• Underlying medical conditions
• Individual response to avanafil

For some people, allowing more than the minimum 15 minutes may provide a more predictable experience.

Does Spedra 200mg Need Stimulation to Work?

Yes.

Spedra does not automatically trigger an erection.

The official product information states that stimulation is required for a response to avanafil.

This remains true even with the maximum 200mg dose.

Taking a larger dose does not remove the need for the normal physiological signals that begin the erection process.

Can You Take Spedra 200mg With Food?

Yes, Spedra can be taken with food, but food may make it take longer to work.

Avoid grapefruit juice for 24 hours before taking Spedra.

The effect has been studied specifically with avanafil 200mg.

When 200mg avanafil was taken with a high-fat meal:

• The average time to peak concentration was delayed by approximately 1.25 hours
• Peak avanafil concentration was reduced by approximately 39%
• Total overall drug exposure was not significantly changed

This means the main food-related effect is on the speed and peak of absorption, not food completely preventing avanafil from being absorbed.

Can You Take Spedra 200mg on a Full Stomach?

Yes.

Spedra is not required to be taken on an empty stomach. However, a full or high-fat meal can delay its onset.

This is particularly relevant for someone expecting Spedra 200mg to work within the shortest advertised time.

If the medicine is taken after a heavy meal, its effect may appear later than when it is taken fasting.

Therefore, an apparently slow response following a large meal should not automatically be interpreted as failure of the 200mg dose.

How Often Can You Take Spedra 200mg?

The standard maximum recommended dosing frequency for Spedra is once per day.

That means you should not take:

one 200mg tablet and then another dose later the same day because the first appears not to have worked.

Taking more than recommended may increase the frequency or severity of adverse effects. The patient leaflet instructs anyone who takes too much Spedra to contact their doctor.

Some medicine interactions require an even lower maximum avanafil dose or a longer interval between doses.

Can You Take More Than 200mg of Spedra?

200mg is the maximum recommended dose under the standard authorised dosing guidance.

Higher doses should not be used in an attempt to obtain a stronger effect.

Clinical studies of overdose have found that greater exposure can increase the incidence and severity of adverse effects.

If Spedra 200mg is repeatedly ineffective, the safer approach is to review:

• Whether it is being used correctly
• Whether food or alcohol is affecting the response
• Whether the underlying cause of ED needs investigation
• Whether another treatment strategy is more appropriate

rather than exceeding 200mg.

Start Your Free Assessment

Can Spedra 200mg Be Taken Every Day?

Spedra is an as-needed treatment, and the authorised dosing information allows a maximum standard frequency of once per day.

This should not be confused with a recommendation that every patient should automatically take 200mg every day.

The dose and frequency should follow the prescription provided for the individual.

If very frequent ED treatment is required, the overall treatment approach can be reviewed rather than simply assuming that daily use of the maximum avanafil dose is necessary.

How Effective Is Spedra 200mg?

Clinical trials demonstrate that avanafil 200mg is effective for erectile dysfunction at a population level.

Across controlled trials, all authorised avanafil doses produced statistically significant improvements in the main measures of ED compared with placebo.

In the general ED population, successful intercourse was reported for approximately 59% of attempts with 200mg, compared with roughly 28% with placebo.

The medicine was also studied in men with diabetes and in men with ED following certain prostate surgery, where 200mg also produced better results than placebo.

Clinical-trial averages do not guarantee an individual outcome.

Does Spedra 200mg Work for Everyone?

No.

Even the maximum authorised dose does not work successfully for every person or on every occasion.

In clinical studies, successful attempts occurred more often with avanafil than placebo, but success rates remained well below 100%.

Poor response may be influenced by factors such as:

• Severe vascular ED
• Diabetes-related nerve or vascular damage
• Incorrect timing
• A substantial meal
• Inadequate stimulation
• Medicine interactions
• Other underlying medical conditions

If 200mg repeatedly provides inadequate results despite correct use, further dose escalation is not recommended because 200mg is already the authorised maximum.

Why Might Spedra 200mg Not Work?

There can be several reasons.

First, Spedra requires stimulation. Even 200mg will not independently produce an erection.

Second, food may delay absorption. A high-fat meal has been shown to delay peak avanafil concentration by approximately 1.25 hours at the 200mg dose.

Third, the underlying ED may be relatively resistant to PDE5-inhibitor treatment.

Clinical outcomes were lower among men with diabetes or ED following prostate surgery than among the general ED population, demonstrating that the underlying cause can affect response.

Finally, other medicines or medical conditions may influence suitability or response.

Can Alcohol Affect Spedra 200mg?

Yes.

Avanafil and drinking alcohol can both contribute to reductions in blood pressure. Combining them can increase the likelihood of symptomatic hypotension, including dizziness or fainting, and may make reliable erections less likely.

Excessive alcohol can also make erection difficulties worse independently of the medicine.

Because Spedra 200mg is the highest authorised avanafil strength, following the alcohol advice supplied with the medicine is particularly important.

What Are the Common Side Effects of Spedra 200mg?

Avanafil can cause side effects at any authorised dose.

In the overall clinical development programme, the most common recognised adverse reactions included:

• Headache
• Flushing
• Nasal congestion

Up to 1 in 10 people may experience common side effects.

These are categorised as common adverse reactions in the authorised UK product information.

Other less common effects can include dizziness, indigestion, nausea, blurred vision, palpitations, back pain, fatigue and skin rash.

Taking a higher dose does not guarantee that side effects will occur, but increasing drug exposure can affect tolerability. Dose selection is therefore based on both effectiveness and side effects.

Can Spedra 200mg Cause a Headache?

Yes.

Headache is classified as a common avanafil side effect in UK medicine information.

If headaches repeatedly occur or are troublesome, discuss them with a healthcare professional rather than changing the dose yourself.

Someone who has been increased from 100mg to 200mg but develops unacceptable adverse effects may require their treatment to be reviewed.

Can Spedra 200mg Cause Flushing?

Yes.

Flushing is another adverse reaction categorised as common with avanafil.

It is related to avanafil's effects on blood vessels.

Mild flushing may resolve as the medicine's effects wear off, but persistent or concerning symptoms should be discussed with a healthcare professional.

Can Spedra 200mg Cause a Blocked Nose?

Yes.

Nasal congestion is listed as a common adverse reaction to avanafil.

Sinus congestion is also reported but is categorised as uncommon.

These effects can vary between individuals and treatment occasions.

What Serious Spedra 200mg Side Effects Need Urgent Attention?

An erection lasting four hours or longer requires immediate medical attention.

The authorised product information warns that untreated priapism can damage penile tissue and may lead to permanent loss of erectile function.

The following serious side effects require urgent medical treatment.

Sudden significant changes in vision or hearing also require prompt medical assessment. Seek immediate help from a doctor or pharmacist if there is a sudden decrease or loss of hearing or vision, including symptoms affecting one or both eyes.

Chest pain and a severe allergic reaction also need immediate emergency assessment.

These symptoms should not be regarded as evidence that a high-strength ED treatment is simply "working strongly."

See the patient information leaflet for the full safety list.

Who Should Not Take Spedra 200mg?

Spedra 200mg is not suitable for everyone.

Avanafil is contraindicated in people taking nitrate medicines used for angina or chest pain, or nitric oxide donors, because the combination can cause low blood pressure.

It is also contraindicated in certain people with:

• A heart attack, stroke or life-threatening heart rhythm problem within the previous six months
• Severe uncontrolled high blood pressure
• Very low blood pressure
• Unstable angina
• Certain heart failure
• Severe kidney impairment
• Severe liver impairment
• Particular serious eye conditions

Cardiovascular status should be considered before erectile dysfunction treatment is started.

Can You Take Spedra 200mg With Nitrates?

No.

Avanafil must not be used with organic nitrate medicines or nitric oxide donors.

The combination can significantly increase the blood-pressure-lowering effects of nitrates and potentially produce dangerous hypotension.

Anyone taking treatment for angina or chest pain, or another cardiovascular condition should provide a complete medicine history before avanafil is prescribed.

Can You Take Spedra 200mg With Alpha-Blockers?

Extra caution is required.

Combining avanafil with an alpha-blocker can produce additional blood-pressure lowering. The authorised guidance states that people who are stable on alpha-blocker treatment should start avanafil at the lowest 50mg dose, rather than beginning with 200mg.

This is a clear example of why the maximum-strength tablet is not suitable simply because someone wants the strongest available Spedra dose.

Can You Take Spedra 200mg With Other Medicines?

Some other medications and other medicines significantly affect how avanafil is metabolised.

Potent CYP3A4 inhibitors are contraindicated with Spedra.

Certain HIV protease inhibitors and antifungal medications are relevant examples of important interactions.

With certain moderate CYP3A4 inhibitors, the maximum recommended avanafil dose is only 100mg, with at least 48 hours between doses.

Therefore, Spedra 200mg may specifically be inappropriate for someone taking one of these interacting medicines.

Tell your doctor or pharmacist about prescription medicines, over-the-counter products and herbal remedies.

A complete medication review is essential before the 200mg strength is prescribed.

Can Spedra 200mg Be Combined With Another ED Medicine?

This should not be done independently with other erectile dysfunction treatments.

The authorised Spedra information states that the safety and effectiveness of combining avanafil with other PDE5 inhibitors or other ED treatments have not been established and advises patients not to use these combinations.

Spedra should not be taken within 24 hours of other ED medications.

If Spedra 200mg does not provide adequate results, combining it with another ED medicine without medical guidance is not an appropriate substitute for a treatment review.

A clinician can help decide the right treatment if the current medicine is inadequate.

Can Men With Diabetes Take Spedra 200mg?

Diabetes itself does not require routine avanafil dose adjustment, according to the authorised product information.

Avanafil 200mg has also been studied specifically in men with diabetes and ED.

In that group, approximately 40% of attempts with avanafil 200mg resulted in successful intercourse, compared with approximately 34% with 100mg and 21% with placebo.

However, diabetes can affect both nerves and blood vessels, so treatment response can differ substantially between individuals.

Can Older Men Take Spedra 200mg?

Age by itself does not require routine avanafil dose adjustment in adults aged 65 or older, although authorised information notes that data are limited in people aged 70 and above.

Whether 200mg is appropriate should still depend on individual effectiveness, tolerability, cardiovascular status, other medicines, kidney function and liver function.

Older age alone is therefore not a reason either to use or avoid the maximum dose.

Can You Take Spedra 200mg With Kidney Problems?

The answer depends on severity.

No routine dose adjustment is required for mild to moderate renal impairment, although clinical-trial participants with impaired kidney function showed lower effectiveness than those with normal renal function.

Spedra is contraindicated in severe renal impairment.

Someone with known kidney disease should therefore have their suitability assessed rather than selecting Spedra 200mg without clinical review.

Can You Take Spedra 200mg With Liver Problems?

Spedra is contraindicated in severe liver impairment.

For mild to moderate hepatic impairment, the authorised guidance recommends starting with the minimum effective dose and adjusting according to tolerability.

This means that automatically using the maximum 200mg strength would not normally be the starting approach for someone with liver impairment.

What Should You Do If Spedra 100mg Does Not Work?

If 100mg has been used correctly but provides an inadequate response, a clinician may consider increasing the dose to 200mg if the higher strength is suitable and the lower dose has been tolerated.

Before escalation, it is useful to consider:

• Whether enough time was allowed
• Whether a substantial meal delayed absorption
• Whether stimulation was adequate
• Whether alcohol affected the response
• Whether another medicine may be interacting
• Whether the underlying ED requires further assessment

The goal is not simply to reach the highest dose as quickly as possible. It is to find the lowest suitable dose that provides an adequate response with acceptable tolerability.

What If Spedra 200mg Does Not Work?

If the maximum 200mg dose repeatedly does not work despite correct use, do not increase the dose further.

The authorised maximum is 200mg, normally no more than once per day.

Persistent non-response may indicate that:

The underlying ED is relatively severe, significant vascular or nerve disease is present, another medicine is contributing, psychological factors are involved, or a different treatment strategy is needed.

The product information recommends identifying underlying causes of erectile dysfunction before and during treatment rather than treating the symptom in isolation.
