The information provided in the summary table is for reference only. It is important to consult a qualified healthcare professional before starting any erectile dysfunction treatment, including Tadalafil.

Why choose Tadalafil pill?

Many men prefer to use tadalafil as, when taken daily, it enables them to have sex more spontaneously, just as they would without medication. Another great benefit of tadalafil over other forms of ED medication is how long it remains active in the body for, in some cases, for up to 3 days.

For many men, ED can cause high levels of stress and anxiety and, as such, easing the symptoms through the use of medication such as tadalafil. It can reduce their worry, and when this happens, the amount of ED occurrences can naturally decrease as it is happening because of emotional concerns such as stress at work or due to the impotence itself.

It has also been shown to increase the intravaginal ejaculatory latency time, or the time taken to ejaculate during penetration, by up to two and half minutes.

How effective is Tadalafil?

Studies show tadalafil increases the flow of blood to the penis, and it is this accumulation of blood which causes an erection. The medication relaxes the veins to the penis and allows a man to achieve and keep his erection, enabling him to be effectively stimulated and have intercourse.

The most effective starting dosage is often recommended at 10mg to be taken before sexual intercourse. The medication remains active in your system for up to 2 days allowing you to have sex as and when you please during this time.

Certain substances are created during sexual stimulation, including nitric oxide, cGMP and phosphodiesterase type 5 or PDE5. In men with ED, the PDE5 destroys the cGMP, which is what contracts blood vessels carrying the blood, helping to keep the erection firm. When cGMP is removed in this way, the blood vessels return to normal, and in turn, the erection is lost. Tadalafil is a PDE5 inhibitor and has been found to effectively stop the destruction of cGMP from occurring, thus allowing the user to retain his erection effectively.

How does Tadalafil work?

Known as a PDE5 inhibitor, the medication helps to treat erectile dysfunction by allowing a man to achieve and keep an erection. It does so by keeping the blood vessels leading to and within the penis relaxed, allowing plenty of blood to flow, causing firmness.

By inhibiting the enzyme PDE5, which destroys a substance released during sexual activity known as cGMP, which is designed to regulate the flow of blood to the penis, thus keeping it firm, means tadalafil is found to be a highly effective option for many men.

What is contained in Tadalafil?

The active ingredient in each tablet is tadalafil which comes as 2.5mg, 5mg, 10mg or 20mg.

The inactive substances are:

  • Lactose monohydrate
  • Croscarmellose sodium
  • Hypromellose
  • cellulose
  • microcrystalline
  • Sorbitan stearate
  • Magnesium stearate

Taking Tadalafil daily?

Due to tadalafil’s prolonged release half-life, up to 5mg may be prescribed to be taken daily, meaning the drug remains at a steady level in the body, thus separating medication from sexual intercourse and enabling the user to have sex as and when desired. It needs to be taken once a day at the same time and in the case of the daily tablet, preferably on an empty stomach. Anything more than a small wine or beer is not advised before taking your tablet, as it can affect your ability to get an erection, thus causing it to work counteractively against the medication. Mixing alcohol with the drug can also increase the risk of hypotension.

The daily dose is usually 2.5mg but can be as much as 5mg in some cases, though this will be discussed with your doctor before beginning a prescription. It can take around 4 to 6 days for the drug to build up in your system, after which you will respond to sexual stimulation as usual.

In many cases, patients taking a lower daily dose also found that they suffered fewer or more minor forms of the potential side effects experienced in comparison to the higher dosage.


How should I take Tadalafil?

As with any medication, it is to be taken as prescribed by your doctor or as advised by your pharmacist though you are not to take more than one per day. It is recommended that you take it whole, with water and with or without food, though often it is more effective when taken on an empty stomach. Eating grapefruit or drinking its juice can make tadalafil more potent and, therefore, potentially dangerous; as such, it is only to be consumed with caution.

Your doctor will advise you of the best way to take the medication, though there are 2 main ways to do so:

  • Taken as needed, often around half an hour prior to sexual activity. This dosage may last anywhere up to 72 hours.
  • Taken daily in a lower dosage, which enables the patient to keep a steady level of medication in their system and therefore have sex as and when without worrying about taking medication and waiting.

This would need to be discussed with your doctor because dosage and the regularity with which you take it would be based on any underlying health issues.

How long can I take Tadalafil for?

In studies of up to 2 years, tadalafil was found to be safe and effective in doses of 5 to 20mg, either taken as needed or on a daily basis.

Side Effects

Common side effects when using Tadalafil and how to overcome them include:

  • Headaches: drink plenty of water and rest until you feel better
  • nausea/feeling sick: take the medicine after consuming a well-balanced meal
  • Red face: restand try to get some fresh air
  • Stuffy nose: this side effect should wear off over time
  • Muscle aches: rest and take a warm bath

In very rare cases, tadalafil can affect the blood flow to the optic nerve, causing usually short term, sudden visual impairment. If this happens, discontinue the treatment and seek medical help.

Other warnings to consider

Tadalafil cannot be taken alongside certain drugs, including nitrate prescriptions for heart issues, as this can lead to a dangerous drop in blood pressure.

There are several other drugs, including antifungals, antidepressants, antibiotics and barbiturates which are not recommended to be taken alongside tadalafil. A more extensive list can be found here, and you can discuss this further with your health practitioner prior.

An erection which will not go away after several hours can be particularly dangerous and can cause long-term damage. This is known as priapism and requires immediate medical attention.

Who should not take Tadalafil

Erectile dysfunction treatments can prove to be harmful to those with pre-existing medical conditions, particularly those who suffer from high blood pressure or hypertension. Therefore, it is advised to consult a doctor face-to-face before starting Tadalafil. In addition, treatments can often interact negatively with the medications you are currently on, so it is crucial to be transparent about the medicines you are taking – whether they are prescribed or not.

What is the difference between Tadalafil Tablets and Cialis Tablets?

Both Tadalafil and Cialis are effectively used for the treatment of erectile dysfunction, the main difference is branding and price. Cialis is the branded version of Tadalafil making it more expensive.

Can I take Tadalafil Tablets on an empty stomach?

It is safe to take Tadalafil Tablets on an empty stomach, however to prevent any nausea like feeling it is advised to take them after having consumed a well balanced and healthy meal.

Can women take Tadalafil tablets?

Yes. Trans women can take Tadalafil tablets. In addition to this, women can take Tadalafil to treat high blood pressure in the lungs – if prescribed by their GP.

Can Tadalafil permanently cure ED?

No, Tadalafil is an erectile dysfunction treatment. It helps manage the condition's symptoms while helping you achieve and maintain erections – with sexual stimulation. It is not a cure for erectile dysfunction. Instead, it treats the condition temporarily.
