Tadalafil Tablets for Erectile Dysfunction

Tadalafil tablets are a well-established treatment for erectile dysfunction (ED). They contain the same active ingredient found in Cialis®, helping men who have difficulty getting or maintaining an erection suitable for sexual activity.

One of the features that makes tadalafil different from some other erectile dysfunction treatments is its longer duration of action. A single dose may remain effective for up to 36 hours, giving a wider window of opportunity compared with some alternatives. This is why tadalafil is sometimes referred to as the "weekend tablet".

Tadalafil does not increase sexual desire and it does not cause an automatic erection. Sexual stimulation is still required for the medicine to work. Instead, it helps improve blood flow to the penis, making it easier to achieve and maintain an erection when sexually aroused.

At Everyday Meds, tadalafil is available through a secure online consultation. Before treatment can be supplied, a qualified prescriber will review your medical information to check whether tadalafil is suitable and safe for you. This assessment helps identify any medicines, medical conditions or risk factors that may affect treatment.

Erectile dysfunction is common and can affect men of all ages, although it becomes more common with increasing age. Many men find it difficult to discuss, but seeking treatment is a normal healthcare decision. For some men, ED may be linked to physical health conditions, lifestyle factors or emotional wellbeing.

This guide explains how tadalafil works, how to take it, possible side effects, and what to expect if you are considering tadalafil on-demand treatment in the UK.

Meet Tadalafil

Tadalafil belongs to a group of medicines known as phosphodiesterase type 5 (PDE5) inhibitors.

It is licensed for the treatment of erectile dysfunction and has been used by millions of men worldwide. Generic tadalafil contains the same active ingredient as Cialis® and must meet the same quality, safety and efficacy standards required for licensed medicines in the UK.

What is tadalafil used for?

Tadalafil is primarily used to treat erectile dysfunction. Erectile dysfunction is the persistent inability to achieve or maintain an erection firm enough for satisfactory sexual activity.

Some formulations of tadalafil are also licensed for other medical conditions. However, the on-demand tadalafil tablets supplied for ED are prescribed specifically to help men experiencing erection difficulties.

How does tadalafil work?

During sexual stimulation, the body releases nitric oxide within the penis. This triggers a chain of events that relaxes blood vessels and increases blood flow.

An enzyme called PDE5 breaks down the chemical messenger involved in this process. Tadalafil works by blocking PDE5, allowing blood vessels to remain relaxed for longer and improving blood flow when sexual stimulation occurs.

This may help men achieve and maintain an erection more easily.

Available strengths

Tadalafil on-demand tablets are commonly available in:

• Tadalafil 10mg tablets
• Tadalafil 20mg tablets

The appropriate strength depends on individual circumstances and previous response to treatment.

Some men begin with tadalafil 10mg and may remain on this dose if it works well for them. Others may require tadalafil 20mg following clinical review.

When may tadalafil be prescribed?

Tadalafil may be considered when a man experiences erectile dysfunction that is affecting sexual activity or quality of life.

A prescriber will consider:

• Your age
• Your medical history
• Current medications
• Cardiovascular health
• Previous ED treatments
• Potential medicine interactions

Treatment will only be supplied if it is considered clinically appropriate.

Clinical Trial Snapshot

Clinical studies have shown that tadalafil can improve erectile function in many men with ED across a range of age groups and underlying causes.

Research published during the development of tadalafil found significantly improved erectile function scores compared with placebo in men with erectile dysfunction.

Tadalafil Comparison Guide

Both medicines are licensed treatments for erectile dysfunction. The most suitable option depends on individual circumstances, medical history and personal preference.

Your Tadalafil Treatment Journey

Starting erectile dysfunction treatment is often simpler than many people expect.

The first step is completing an online consultation. This allows the prescriber to understand your symptoms, overall health and any factors that could influence treatment.

You may be asked questions about:

• How long you have experienced ED symptoms
• Whether you can achieve any erections
• Current medications
• Previous ED treatments
• Smoking and alcohol use
• Medical conditions such as diabetes or heart disease

Providing accurate information helps ensure treatment decisions are made safely.

Choosing the right starting dose

For many men, tadalafil 10mg is a suitable starting point.

The dose is usually taken before anticipated sexual activity rather than every day.

However, prescribing decisions are individual. Some men may be prescribed a different dose depending on their health, previous treatment experience or clinical circumstances.

Dose reviews and adjustments

After using tadalafil, your response may be reviewed during future consultations.

If the medicine is effective and well tolerated, the same dose may continue. If the response is not adequate, a prescriber may consider whether a different strength or treatment approach is appropriate.

Any dose change should only take place following professional review.

Ongoing safety considerations

Erectile dysfunction treatment is not simply about prescribing a tablet.

Changes in health, new medications or new medical diagnoses can affect which ED treatments remain suitable over time.

This is one reason why periodic reviews may be recommended, particularly if your circumstances change.

How Tadalafil Fits Into Erectile Dysfunction Treatment

Erectile dysfunction affects men in different ways.

For some, symptoms occur occasionally. For others, erection difficulties happen more regularly and begin to affect confidence, relationships or overall wellbeing.

Tadalafil is one of several licensed treatment options available in the UK. It is often chosen by men who prefer a longer treatment window rather than planning sexual activity within a shorter timeframe.

Unlike treatments that may only remain active for a few hours, tadalafil can continue working for significantly longer after a single dose. This may allow greater flexibility around timing.

However, it is important to have realistic expectations.

Tadalafil does not permanently cure erectile dysfunction. It also does not address every possible cause of ED. If erection difficulties are linked to an underlying medical condition, further investigation or treatment may sometimes be appropriate.

The role of the prescriber is not only to assess suitability for tadalafil but also to identify whether symptoms may require additional medical assessment.

Why Lifestyle Changes Still Matter

Although medicines such as tadalafil can help manage erectile dysfunction symptoms, lifestyle factors often play an important role in sexual health.

Many of the same factors that affect heart and blood vessel health can also affect erections. This is because erections depend on healthy blood flow, nerve function and hormone balance.

Physical activity

Regular exercise can support cardiovascular health, improve circulation and help maintain a healthy weight.

Even moderate activities such as brisk walking, cycling or swimming may have a positive effect on overall health and wellbeing.

Maintaining a healthy weight

Being overweight can increase the risk of conditions associated with erectile dysfunction, including:

• Type 2 diabetes
• High blood pressure
• Cardiovascular disease
• Sleep apnoea

Weight management may form part of a broader approach to improving health.

Smoking

Smoking can damage blood vessels and reduce blood flow throughout the body, including to the penis.

Men who smoke are more likely to experience erectile dysfunction than non-smokers.

If you smoke, stopping may benefit both your general health and sexual health.

Alcohol

Excessive alcohol consumption can affect erections both in the short term and over time.

While moderate alcohol consumption may not prevent tadalafil from working, heavy drinking can make it more difficult to achieve an erection and may increase the likelihood of side effects such as dizziness.

Sleep

Poor sleep can affect hormone levels, mood and energy levels.

Conditions such as obstructive sleep apnoea have also been linked with erectile dysfunction.

Stress and emotional wellbeing

Stress, anxiety and relationship difficulties can contribute to ED symptoms.

Even when erectile dysfunction has a physical cause, emotional factors can sometimes worsen symptoms.

Looking after mental wellbeing is therefore an important part of overall sexual health.

Healthy eating

A balanced diet that supports cardiovascular health may also support erectile function.

Foods rich in vegetables, fruits, whole grains, lean protein and healthy fats are commonly recommended as part of a healthy lifestyle.

Lifestyle changes do not replace medical treatment where treatment is needed, but they can complement it and support overall health.

Directions for Use

Taking tadalafil correctly can help ensure you get the most from your treatment.

Always follow the instructions provided by your prescriber and the patient information leaflet supplied with your medicine.

How to take tadalafil

Swallow the tablet whole with water.

Tadalafil can be taken with or without food.

Do not take more tablets than prescribed.

When should I take tadalafil before sex?

Tadalafil is usually taken before anticipated sexual activity.

Many men take their dose around 30 minutes before sexual activity, although the exact timing can vary between individuals.

Because tadalafil has a longer duration of action than some other ED treatments, it may continue working for up to 36 hours after a dose.

This does not mean you will have an erection for 36 hours. It means the medicine may remain active in your body during that period and can help support erections when sexual stimulation occurs.

Does tadalafil work straight away?

No.

Tadalafil needs time to be absorbed into the bloodstream before it can begin working.

Most men will not notice an immediate effect after taking a tablet.

Does tadalafil work without sexual stimulation?

No.

Sexual stimulation is still required.

Tadalafil helps the body's natural erectile response but does not automatically produce an erection.

Can you take tadalafil with food?

Yes.

Food does not significantly affect how tadalafil works.

You can take your tablet with a meal or on an empty stomach.

Can you drink alcohol while taking tadalafil?

Small amounts of alcohol are unlikely to cause problems for many people.

However, drinking excessive amounts of alcohol may:

• Reduce erectile performance
• Increase dizziness
• Increase the likelihood of low blood pressure symptoms
• Make side effects more noticeable

If you choose to drink alcohol, moderation is generally advisable.

How often can I take tadalafil?

Tadalafil on-demand tablets should not usually be taken more than once in a 24-hour period.

Always follow the specific instructions provided by your prescriber.

Missed dose

Because tadalafil on-demand treatment is taken when needed rather than on a fixed schedule, missed doses are generally not relevant.

Do not take extra tablets to make up for a missed dose.

Storage advice

Keep tadalafil:

• Out of the sight and reach of children
• In its original packaging
• Below the storage temperature stated on the pack
• Away from excess heat and moisture

Do not use tablets after the expiry date shown on the packaging.

Why an Online Consultation Is Required

Tadalafil is a prescription-only medicine in the UK.

This means it cannot be supplied safely without an assessment by an appropriately qualified prescriber.

Identifying medicines that may interact

Some medicines can interact with tadalafil and increase the risk of side effects or complications.

Examples include:

• Nitrate medicines used for angina
• Certain medicines for high blood pressure
• Some antifungal medicines
• Some antibiotics
• Certain HIV medicines

Your consultation helps identify any potential interactions before treatment is supplied.

Assessing underlying health conditions

Erectile dysfunction can sometimes be linked to other health conditions.

These may include:

• Heart disease
• Diabetes
• High blood pressure
• High cholesterol
• Hormonal disorders

In some cases, ED symptoms may be one of the earliest signs of an underlying health issue.

Ensuring treatment is suitable

Not every erectile dysfunction treatment is suitable for every patient.

The online consultation allows the prescriber to determine whether tadalafil is appropriate based on your health history and current circumstances.

Supporting patient safety

The assessment process is designed to support safe prescribing and ensure that medicines are supplied appropriately.

If further information is required, the prescriber may ask additional questions before making a decision.

In some situations, treatment may not be approved if it is not considered suitable.

Is Tadalafil Right For You?

Tadalafil may be suitable for adult men who are experiencing erectile dysfunction and have been assessed as appropriate candidates for treatment following a clinical review.

You may be suitable if:

• You have symptoms of erectile dysfunction
• You are looking for an on-demand treatment option
• You have completed a medical assessment
• A prescriber considers tadalafil appropriate for your circumstances

You may require additional assessment if:

• You have significant cardiovascular disease
• You have uncontrolled high blood pressure
• You have recently experienced a heart attack or stroke
• You have liver or kidney problems
• You are taking medicines that may interact with tadalafil

Tadalafil may not be suitable if:

• You take nitrate medicines for chest pain
• You have been advised to avoid sexual activity for medical reasons
• You have certain rare inherited eye conditions
• A prescriber determines that another treatment would be more appropriate

The decision to prescribe tadalafil is always based on individual clinical circumstances rather than age alone.

Side Effects of Tadalafil

Like all medicines, tadalafil can cause side effects, although not everybody experiences them.

Most side effects are mild to moderate and often improve as the medicine leaves the body.

Common tadalafil side effects

The most frequently reported side effects include:

• Headache
• Facial flushing
• Indigestion
• Nasal congestion
• Back pain
• Muscle aches

These effects are usually temporary.

Can tadalafil cause headaches?

Yes.

Headache is one of the most commonly reported side effects of tadalafil.

Staying hydrated may help, but persistent or severe headaches should be discussed with a healthcare professional.

Can tadalafil cause indigestion?

Yes.

Some men experience indigestion, heartburn or stomach discomfort after taking tadalafil.

Taking the medicine with water and avoiding large amounts of alcohol may help reduce discomfort for some people.

Less common side effects

Less common side effects can include:

• Dizziness
• Blurred vision
• Palpitations
• Tiredness
• Nausea

Serious side effects

Serious side effects are uncommon but require urgent medical attention.

These include:

• Signs of an allergic reaction
• Sudden loss of vision
• Sudden loss of hearing
• Chest pain during sexual activity
• An erection lasting longer than four hours (priapism)

If any of these occur, seek immediate medical attention.

Who Can Benefit From Tadalafil?

Tadalafil is licensed for the treatment of erectile dysfunction in adult men.

It may be considered for men whose erection difficulties are affecting their sexual relationships, confidence or quality of life.

Erectile dysfunction can occur for many reasons. Some men experience symptoms linked to physical health conditions, while others find that stress, anxiety or lifestyle factors contribute to the problem. In many cases, several factors may be involved at the same time.

Tadalafil may be prescribed to men who:

• Have difficulty achieving an erection
• Have difficulty maintaining an erection during sexual activity
• Want an on-demand treatment option
• Prefer a longer treatment window than some alternative ED medicines provide
• Have been assessed as suitable by a prescriber

Because tadalafil remains active in the body for longer than some other ED treatments, some men find that it offers greater flexibility around timing. However, treatment choice is personal and should be based on individual circumstances rather than duration alone.

The most appropriate erectile dysfunction treatment will depend on factors such as medical history, current medicines, response to previous treatments and personal preference.

Possible Benefits of Tadalafil Treatment

Tadalafil is prescribed to help manage the symptoms of erectile dysfunction.

When treatment is suitable and effective, potential benefits may include:

• Improved ability to achieve an erection suitable for sexual activity
• Improved ability to maintain an erection during sexual activity
• Greater confidence in intimate situations for some men
• A longer window of opportunity for sexual activity compared with some alternative treatments
• Flexibility due to its extended duration of action

It is important to remember that results vary between individuals.

Some men notice a good response when using tadalafil, while others may find that a different dose or treatment approach is more appropriate. Erectile dysfunction can have multiple causes, and treatment response may be influenced by underlying health conditions, lifestyle factors and emotional wellbeing.

Tadalafil is intended to support erectile function when sexual stimulation occurs. It is not designed to increase sexual desire and does not address every possible cause of erectile dysfunction.

Tadalafil 10mg vs Tadalafil 20mg

One of the most common questions patients ask is whether tadalafil 20mg is stronger than tadalafil 10mg.

The simple answer is yes. A 20mg tablet contains twice as much active ingredient as a 10mg tablet.

However, that does not automatically mean it is the right choice for everyone.

Tadalafil 10mg

Tadalafil 10mg is often used as a starting dose for on-demand treatment.

For many men, this strength provides an adequate response while maintaining a favourable side-effect profile.

Tadalafil 20mg

Tadalafil 20mg may be considered if a lower dose has not provided a sufficient response and the medicine is otherwise well tolerated.

A prescriber may recommend this strength following assessment and review.

What happens if tadalafil 10mg does not work?

Several factors can influence treatment response.

These include:

• Timing of the dose
• Alcohol consumption
• Food intake around the time of dosing
• Anxiety or stress
• Underlying health conditions
• Incorrect use of the medicine

It may take more than one attempt to understand how tadalafil works for you.

If tadalafil 10mg does not provide the desired effect, speak to your prescriber rather than increasing the dose yourself. A clinical review can help determine whether a different strength or alternative treatment may be more appropriate.

Tadalafil and Other Medicines

Before taking tadalafil, it is important to make sure your prescriber is aware of all medicines you currently use.

This includes:

• Prescription medicines
• Pharmacy medicines
• Herbal remedies
• Supplements

Some medicines can affect how tadalafil works or increase the risk of side effects.

Can I take tadalafil with nitrates?

No.

Tadalafil must not be taken with nitrate medicines.

Nitrates are commonly prescribed for chest pain (angina) and some heart conditions.

Examples include:

• Glyceryl trinitrate (GTN)
• Isosorbide mononitrate
• Isosorbide dinitrate

Combining tadalafil with nitrates can cause a potentially dangerous drop in blood pressure.

For this reason, tadalafil is contraindicated in patients using nitrate medicines.

Can I take tadalafil with Viagra or sildenafil?

No.

Tadalafil should not normally be taken alongside sildenafil (Viagra®) or other PDE5 inhibitors.

These medicines work in similar ways, and combining them may increase the risk of side effects without providing additional benefit.

If your current treatment is not working as expected, discuss this with your prescriber rather than combining medicines.

Medicines that may require additional review

Examples include:

• Alpha-blockers used for prostate enlargement or blood pressure control
• Certain antifungal medicines
• Certain antibiotics
• Some HIV treatments
• Medicines that affect blood pressure

This is why completing your consultation accurately is so important.

Erectile Dysfunction and Your Overall Health

Although erectile dysfunction is common, it should not always be viewed as an isolated issue.

In some men, ED may be associated with underlying health conditions affecting blood vessels, nerves or hormone levels.

Conditions sometimes linked with erectile dysfunction include:

• Type 2 diabetes
• High blood pressure
• High cholesterol
• Obesity
• Cardiovascular disease
• Depression and anxiety
• Hormonal imbalances

For some men, seeking help for erectile dysfunction can lead to the identification of other health issues that may benefit from medical attention.

This is another reason why an appropriate assessment is important before treatment is prescribed.

If you develop new symptoms alongside erectile dysfunction, such as chest pain, breathlessness, unexplained fatigue or significant changes in your health, you should seek medical advice.

Buying Tadalafil Online in the UK

Many men prefer the convenience and privacy of obtaining erectile dysfunction treatment online.

However, it is important to ensure that any online provider follows UK prescribing and pharmacy regulations.

A legitimate online pharmacy should:

• Require a medical assessment
• Use qualified prescribers
• Supply medicines through an appropriately registered pharmacy
• Provide access to professional advice where needed
• Supply licensed medicines sourced through regulated channels

You should be cautious of websites offering prescription medicines without a consultation or claiming that approval is guaranteed.

Safe prescribing requires an individual assessment, and treatment may not be suitable for everyone.

At Everyday Meds, tadalafil is supplied only after a clinical review has been completed and approved by a prescriber.

Storage and Medicine Safety

To maintain the quality of your medication, always follow the storage instructions provided with the product.

Key points include:

• Store tablets in their original packaging
• Protect from excess moisture
• Keep away from direct heat
• Keep out of the sight and reach of children
• Check the expiry date before use

Never share prescription medicines with another person, even if they appear to have similar symptoms.

Treatment suitability is assessed individually, and a medicine that is appropriate for one person may not be suitable for another.

When to Speak to a Healthcare Professional

You should seek medical advice if:

• Erectile dysfunction symptoms are worsening
• Treatment is no longer working as expected
• You experience troublesome side effects
• Your health circumstances change
• You start taking new medications
• You develop symptoms that may suggest an underlying health condition

Regular communication with your healthcare provider helps ensure that treatment remains appropriate and safe over time.

Is Tadalafil On-Demand Right for You?

Tadalafil on-demand tablets may be suitable for adult men who have erectile dysfunction and want a treatment that can be taken before sexual activity rather than every day.

Some men prefer tadalafil because of its longer duration of action compared with some other erectile dysfunction medicines. This may provide greater flexibility around timing, as the medicine can remain active for up to 36 hours after a dose.

A healthcare professional will consider several factors before prescribing tadalafil, including:

• Your age and general health
• Any heart or circulation conditions
• Current medicines
• Previous erectile dysfunction treatments
• Blood pressure
• Any history of stroke or heart attack
• Liver or kidney problems

Who May Be Suitable?

Tadalafil may be considered for men who:

• Have erectile dysfunction affecting sexual activity
• Want an on-demand treatment option
• Have found lifestyle measures alone are not enough
• Have previously responded well to PDE5 inhibitor medicines
• Prefer a longer treatment window

Who May Not Be Suitable?

Tadalafil is not suitable for everyone.

You should not take tadalafil if you:

• Take nitrate medicines for angina or chest pain
• Use recreational nitrite products such as "poppers"
• Have certain serious heart conditions
• Have been advised to avoid sexual activity for medical reasons
• Have previously experienced serious side effects from tadalafil

When Extra Assessment May Be Needed

Additional assessment may be required if you:

• Have diabetes
• Have high blood pressure
• Have kidney disease
• Have liver disease
• Take multiple medicines
• Have a history of cardiovascular disease
• Have Peyronie's disease or other penile conditions

Your prescriber will determine whether tadalafil remains an appropriate option based on your individual circumstances.

Tadalafil Side Effects

Like all medicines, tadalafil can cause side effects, although not everyone experiences them.

Most side effects are mild to moderate and improve as the medicine leaves the body.

Common Tadalafil Side Effects

The most frequently reported side effects include:

• Headache
• Flushing
• Indigestion
• Nasal congestion
• Back pain
• Muscle aches
• Dizziness

These side effects are usually temporary and often resolve without treatment.

Less Common Side Effects

Some people may experience:

• Heartburn
• Nausea
• Stomach discomfort
• Tiredness
• Increased sweating
• Blurred vision
• Eye irritation

Serious Side Effects

Serious side effects are uncommon but require immediate medical attention.

Seek urgent medical advice if you experience:

• Chest pain
• Sudden loss of vision
• Sudden hearing loss
• Signs of an allergic reaction
• An erection lasting longer than four hours (priapism)

Although rare, priapism is a medical emergency and requires immediate treatment.

Can Tadalafil Cause Headaches?

Yes. Headache is one of the most commonly reported tadalafil tablet side effects.

Staying hydrated and limiting excessive alcohol intake may help reduce the likelihood of headaches in some people.

Can Tadalafil Cause Indigestion?

Yes. Indigestion and acid reflux symptoms can occur because tadalafil may relax smooth muscle within the digestive tract.

Taking medicine with food may help some people manage digestive discomfort.

Who Can Benefit From Tadalafil Treatment?

Tadalafil is licensed for the treatment of erectile dysfunction in adult men.

Some men seek treatment when erectile difficulties occur occasionally, while others experience symptoms more frequently.

Treatment may be beneficial for men whose erectile dysfunction:

• Affects confidence
• Impacts relationships
• Causes distress
• Interferes with sexual activity
• Persists despite lifestyle changes

A clinical assessment helps determine whether tadalafil may be appropriate and whether further investigation of underlying causes is needed.

Possible Benefits of Tadalafil On-Demand Treatment

The potential benefits of tadalafil treatment vary between individuals.

Clinical studies have shown that tadalafil can improve erectile function in many men with erectile dysfunction.

Potential benefits may include:

• Improved ability to achieve an erection suitable for sexual activity
• Improved ability to maintain an erection
• Greater flexibility due to the longer treatment window
• Improved sexual confidence for some men
• Reduced impact of erectile dysfunction on quality of life

Response varies between individuals and treatment outcomes cannot be guaranteed.
