Further Information


Erectile dysfunction can be due to many causes, for example, medical factors, age, stress, lifestyle, inadequate rest, or smoking and alcohol. In some of these circumstances, patients can make some changes to combat these effects. In other cases, treatment using medication may be considered. The frequency of your sexual activity will determine which strength of Tadalafil you should select as your preferred treatment.

Tadalafil is the generic name for the popular drug Cialis and is used to treat erectile dysfunction. Tadalafil increases blood flow to the penis allowing for a more prolonged erection. Tadalafil belongs to the drug family Phosphodiesterase Type 5 Inhibitors.


  • There are four strengths of Tadalafil: 2.5mg, 5mg, 10mg, and 20mg
  • Low doses (2.5mg and 5mg) are suitable for taking continuously for patients that may need to combat ED symptoms twice or more a week. They come in pack sizes of 28 tablets (4-week supply) to allow patients to take them daily
  • 2.5 and 5mg: Take one tablet daily as directed
  • 10mg and 20mg come in pack sizes of 4 tablets and are licensed to be taken “as and when required” as opposed to continuously (daily)
  • 10mg and 20mg: Take one tablet 30 minutes before sexual activity. No more than one tablet in 36 hours.


How it works

Tadalafil belongs to a group of drugs known as pde5 inhibitors that work to relax blood vessels that in turn allow for easier blood flow to the penis giving the user a firmer and more prolonged erection. It should be noted that the effects of Tadalafil will only be beneficial under sexual stimulation. Tadalafil should begin to work between thirty and sixty minutes after taking it. However, if you have eaten a heavy meal or consumed alcohol before using Tadalafil, the effects of the drug may be delayed.

Tadalafil remains in the body for 36 hours and is typically taken as a single-dose tablet thirty to sixty minutes before sexual activity. The starting dose for Tadalafil is 10mg though this may be increased to 20mg if found too weak. On the other hand, if your erection lasts longer than you would like, you may adjust the dose and use less. You should not take more than one 10mg 0r 20mg tablet in any 36 hours.

If your preference is to take Erectile Dysfunction that will remain in your body so that you are always ready, Tadalafil is also available in daily dose tablets of 2.5mg and 5mg. This may be ideal for those who are sexually active twice or more a week and would prefer it to be in their system so they do not need to remember to take it each time they engage in sexual activity. Although the daily dose may seem low, as Tadalafil remains in the system for 36 hours this means it builds up to effective levels when taken continuously. If you opt for the daily tablet, you must not increase the dose beyond 5mg daily.

It is not recommended that you take Tadalafil 10mg or 20mg more than once daily. You should wait for at least 36 hours between Tadalafil doses unless you have opted for the 2.5mg or 5mg doses which can be taken daily.

Tadalafil vs Cialis

Tadalafil is the generic name of the branded drug Cialis. Cialis contains the active drug Tadalafil and it is, for this reason, the effects of both drugs are the same. Patients will not receive subpar medication with Tadalafil, though they will save on cost as the patent for the drug is now open, meaning that the company that owns the name Cialis, Lilly, no longer has the sole license for manufacturing Tadalafil.

Tadalafil vs Sildenafil

Tadalafil and Sildenafil, the generic name for Viagra, are part of the same family of drugs. However, the effects of Tadalafil can last longer in patients. Tadalafil can continue to help you achieve an erection for up to thirty-six hours after use; do not be concerned, as the erection itself will not last for this length of time. The thirty-six-hour window simply means that, with the aid of sexual stimulation, you will be able to get an erection without the need to take an extra tablet.

Possible Side Effects

As with all medications, there is a risk that you may experience some negative side effects when using Tadalafil. Often these are mild and will subside, however, if you experience any of the following then you should stop using Tadalafil and consult a medical professional immediately:

  • Chest pain
  • A painful erection that does not subside
  • Vision loss (of any severity affecting one or both eyes)
  • Hearing loss


The most common side effects of Tadalafil, occurring in up to one in ten people are:

  • Pain in the arms and legs
  • Headache
  • Back pain
  • Indigestion
  • Flushes
  • Congestion
  • Dizziness

These side effects are not cause for great concern and should last only a short time. Once the effect of the drug wears away these should subside.


To determine if Tadalafil is a suitable treatment for you, please select your preferred option and proceed to the assessment page.

Tadalafil licensed for erectile dysfunction comes as an orally administered tablet in the following four strengths:

2.5 mg
5 mg
10 mg
20 mg

When taken orally, Tadalafil may begin to work in as little as 30 minutes.

2.5 mg and 5 mg tablets: One tablet daily
10mg and 20mg tablets: One tablet taken 30-60 minutes prior to sexual activity

Can Tadalafil affect fertility?

No, it has no detrimental effect on fertility.

How long will it take Tadalafil to work?

Tadalafil tablets should begin to work within 30-60 minutes. Sexual stimulation is needed for Tadalafil to be fully effective. If you eat a large meal before taking Tadalafil tablets, the effects may be delayed.

How long will the effects of Tadalafil last?

Tadalafil stays in the body for approximately 36 hours. You will still require sexual stimulation for the medicine to work.

Why must you leave 36 hours between doses of 10mg and 20mg but not for 2.5mg and 5mg?

The effects of Tadalafil remain in your body for up to 36 hours, daily dosing of 10mg and 20mg tablets would be detrimental. As the 2.5mg and 5mg are low doses they build up to effective levels when taken continuously and are therefore safe to take daily.

Can I drink alcohol with Tadalafil?

As with most erectile dysfunction (ED) medication, alcohol can increase the chances of hypotension (low blood pressure) while increasing your heart rate. It can cause excessive dizziness and fainting. Alcohol is also a contributing factor to erectile dysfunction.

What does Tadalafil look like?

Tadalafil tablets may vary in appearance from one brand to another and can come in different colours and shapes. If you have a brand preference, please contact us to let us know. All our brands are equally as effective and carefully sourced. Items are all thoroughly checked by our Pharmacy.

Can Tadalafil tablets be used alongside other erectile dysfunction medication?

No, they cannot. All medications that treat erectile dysfunction work the same way and so using multiple forms at one time can cause an overdose and a higher chance of serious side effects.

What strengths of Tadalafil are available?

Tadalafil tablets come in four strengths; 2.5mg, 5mg, 10mg and 20mg.

Why are there so many companies making Tadalafil tablets?

Due to the patent expiring for Lilly (the original manufacturer of the brand Cialis), other manufacturers have been able to manufacture Tadalafil tablets making them more affordable.

Is Tadalafil legal to purchase online in the UK?

Yes, Tadalafil can be purchased online in the UK from GPhC-approved websites. As we are regulated and approved by the GPhC you can be confident with the request. One of our prescribers will issue a prescription (free of charge) to our in-house pharmacy if deemed suitable.

Can I take Tadalafil if I have a history of heart problems?

Tadalafil, as with other drugs used to treat erectile dysfunction, should be used with caution in patients with heart issues. By answering our simple questionnaire, we can determine if Tadalafil will be suitable. You must answer all questions honestly for us to assess your suitability for treatment.

I take nitrates, can I still buy Tadalafil online?

Unfortunately, not. There is a severe reaction between Tadalafil, nitrate tablets, sprays, and Nicorandil tablets. If you take any of these it is important to inform us so that we can help by suggesting alternatives. The effects of taking nitrates with erectile dysfunction medication can be dangerous.

Is Tadalafil suitable for use in women?

No. Tadalafil and other erectile dysfunction medicines are only licensed for use in men.

Can I use Tadalafil if my partner is breastfeeding?

Some studies have shown that ejaculate may contain traces of Tadalafil that can then be secreted in breast milk if no barrier protection is used. It is therefore advisable to avoid using tadalafil with breastfeeding women.

Can I use Tadalafil if my partner is pregnant?

No, the manufacturer advises avoiding it.

Can I drive after taking Tadalafil?

Side effects of using Tadalafil may include blurred vision and dizziness so you should refrain from driving or operating machinery until you know that the drug does not affect you in any of these ways.

Is Tadalafil suitable for me?

To determine if Tadalafil is the right drug to help with your erectile dysfunction, you will need to answer a few simple health-related questions. If your consultant deems Tadalafil to be unsuitable, then they will endeavour to offer alternative options and advice. For many, the root cause of ED is not strictly physical. Alcohol consumption, stress and tiredness can also affect your ability to get and maintain an erection.
