Erectile Dysfunction Doctor Service

Tadalafil film-coated tablet is an efficient treatment, which is indicated to treat erectile dysfunction for adult men. Tadalafil, also known as generic Cialis, is a treatment for ED (Erectile dysfunction).

Tadalafil contains the active substance tadalafil which belongs to a group of medicines called phosphodiesterase type 5 inhibitors. 

They are used for the treatment of erectile dysfunction, and help in a condition which implies difficulties in getting or keeping an erection.  It does this by improving blood flow to the penis when sexually stimulated. This allows men who suffer from ED to achieve firmer and longer lasting erections.

At least one in ten men has trouble getting or keeping an erection at some time. There may be physical or psychological causes, or a mixture of both. Whatever the cause is, due to muscle and blood vessel changes not enough blood stays in the penis to make it hard and keep it hard. Tadalafil will only work when you are sexually stimulated.

Tadalafil is a safe and efficient treatment which allows you to obtain an erection, when sexually stimulated, at any time point during the 24 hours of the day.

Once a day dosing of Tadalafil may be useful to men who anticipate having sexual activity two or more times per week.

Tadalafil May Still Be Effective Up To 36 Hours After Taking The Tablet

What Does This Mean? 

The effects of Tadalafil can last for up to 36 hours after taking a dose. It should be noted, this does not mean that your erection will last this long! In fact, any erection which is painful or lasts more than 4 hours should be brought to the attention of your doctor immediately. The 36-hour effect simply means that you should be able to achieve an erection when sexually stimulated, in the 3 days after taking the pill.

The reason men may use Tadalafil with the right daily dosage is that it maintains levels of Tadalafil in the blood all the time. This means you do not need to remember to take it each time you wish to have sex. Simply take the daily tablet each day, and this should mean you can achieve an erection, whenever you come to engage in sexual activity.

The convenience of not needing to take your medication with you everywhere, and simply taking it with your breakfast each morning, is a change in how traditional ED medications have worked.


How Do You Take Tadalafil?
If taking a 10 or 20mg dose, take one tablet about half an hour before sex. The 2.5mg and 5mg strength are a daily tablet and should be taken at the same time each day.

How Effective Is Tadalafil?
The majority of men who take Tadalafil (around 85%), will notice a firmer and longer-lasting erection.

How Does Tadalafil Work?
Tadalafil enhances the erectile response in men by relaxing the smooth muscle and increasing blood flow. It is one of a class of drugs known as PDE-5 inhibitors

How Long Does Tadalafil Last?
The effects of Tadalafil generally last between 24-36 hours. You will only notice an erection however if you are sexually stimulated. Erections which are painful or last longer than 4 hours require medical attention.

How Long Does Tadalafil Take To Work?
Tadalafil can work as soon as 15 minutes after taking it. However, you should take it about 30 minutes before sexual activity.

What Are The Side Effects of Tadalafil?
Although uncommon, side effects can include nausea, vomiting, and diarrhoea. Tadalafil may also result in nasal congestion, headaches, a pounding heartbeat, facial flushing, slight vertigo and blurred vision.

Can I Take Tadalafil With Nitrates?
No. A dangerous reaction exists between all ED medication and Nitrates. Tadalafil cannot be prescribed by our doctor if you are taking Nicorandil or nitrate-based medication, such as a GTN spray or isosorbide mononitrate tablets for angina.

Can I Take Tadalafil With Alpha-Blockers?
If you are taking alpha-blocking medicines, such as tamsulosin or trazodone, you are advised to wait for at least six hours between taking Tadalafil.

Where Can I Buy Tadalafil?
You can buy Tadalafil from our online pharmacy after completing an online assessment for your suitability for this medication. Tadalafil is a prescription only medicine and requires a doctor to issue a prescription if deemed suitable.

Can I Take 20mg Of Tadalafil?
Yes. While the starting dose of Tadalafil is generally 10mg, in men who do not get a response to this dosage, Tadalafil 20mg can be prescribed.

Do You Need A Prescription To Buy Tadalafil?
Yes. Tadalafil is a prescription only medication, so a doctor must issue a prescription in order to dispense this medication. Our UK online doctor can issue a prescription if you complete an assessment, and it is judged that the medication is suitable for you. This prescription is then passed to the pharmacy for preparation.

Is Tadalafil Legal In The UK?
Yes. Tadalafil is a legal drug, prescribable by GMC registered doctors. Only pharmacies can legally distribute the medication, however. If you were offered Tadalafil from another source, this would not be legal as there would be no prescription issued for the use of the drug. The authenticity of the medicine would also be doubtful so, if buying online, it's important you check the registration status of the pharmacy.

Can I Buy Tadalafil Over The Counter?
No. Tadalafil is a prescription only medication, meaning you will have to have a doctor prescribe you this medication. Unlike Viagra Connect, which became an over-the-counter treatment for ED in 2017, no such license exists for Tadalafil to be sold in this way. A consultation with your GP face to face, or online, will be required to be prescribed the treatment.

Can I Buy Tadalafil Online?
Yes. You can use a UK registered online pharmacy and doctor service, to buy Tadalafil online in the UK. You should check the service is registered, before buying any medications online. Any online pharmacy and doctor service operating legally in the UK will be registered and overseen by at least 3 bodies. The MHRA, the general pharmaceutical council, and one of either the CQC (Care Quality Commission) or HIS (Health Improvement Scotland).

What Is The Difference Between Sildenafil & Tadalafil?
While both drugs are from the same class of drug, the main difference is that Tadalafil is longer acting. The prices are now broadly similar after Tadalafil being available generically, however, Sildenafil is still slightly cheaper.

Is Tadalafil Available On The NHS?
There are specific criteria for the prescribing of Tadalafil and all erectile dysfunction treatments on the NHS. There are a number of conditions which mean you can be prescribed ED treatment by your GP on the NHS. These include men who suffer from Parkinson's, diabetes and some types of cancer. You should speak to your GP for further information if you think you may be eligible for NHS treatment.

What Is The Difference Between Cialis & Tadalafil?
Cialis and Tadalafil contain the same active ingredient (Tadalafil). Cialis is the original branded version of the drug. In November 2017, generic Tadalafil became available, which can be a more affordable option for many. So there is no medical difference between the two medications. You will likely notice that their appearances differ in terms of pill type and packaging, however, this is as far as the differences go. When you take the tablet, there should be no difference in effect.
