What is Tadalafil?

Tadalafil is a prescribed remedy for erectile dysfunction, classified as a PDE-5 inhibitor, supporting men in attaining an erection when the natural process is impeded. Tadalafil is the active ingredient found in Cialis. As tadalafil can be produced by any pharmaceutical company, it is often more economically accessible compared to Cialis. 

What is Tadalafil used to treat?

Primarily prescribed for erectile dysfunction (ED), tadalafil addresses the common challenge faced by men in attaining and maintaining an erection. 

Who can and cannot take medicines containing Tadalafil?

Individuals who are taking specific medications or have certain pre-existing conditions may face limitations in taking tadalafil: 

Medication Interactions: You may be unable to take tadalafil if you are currently using medications such as: 

  • nitrates (e.g., isosorbide mononitrate, glyceryl trinitrate) 

  • some antibiotics (e.g., erythromycin) 

  • antifungals (e.g., ketoconazole and itraconazole) 

  • antivirals (e.g., ritonavir and saquinavir) 

  • alpha-blockers (e.g., tamsulosin, doxazosin, alfuzosin) 

  • other erectile dysfunction medications (e.g., Viagra, Levitra, etc.) 

The consumption of alcohol and grapefruit juice is advised against as these can also interact with tadalafil. 

Pre-existing Conditions: Tadalafil may not be suitable for individuals with the following pre-existing conditions: 

  • Peyronie's disease (a condition causing penile curvature) 

  • heart problems or a history of stroke 

  • certain visual/eye conditions 

  • kidney or liver disease 

  • sickle cell anaemia, multiple myeloma, or leukaemia 

It is crucial to consult with a healthcare professional to assess individual health conditions and medication regimens before considering tadalafil, ensuring its compatibility and safe usage. 

In the UK, tadalafil is not authorised for use in women, and therefore, it should not be taken by women as it cannot be safely prescribed by a doctor.

What’s the difference between Tadalafil and Sildenafil?

Tadalafil and sildenafil contain different active ingredients. Tadalafil is the active ingredient in Cialis, whereas sildenafil is the active ingredient in Viagra. Both increase blood flow to the penis, enabling firmer erections. However, some men may find they have a stronger reaction when taking one of these medications. The main difference between them is that Cialis is a longer-lasting medication, and the effects last for up to 36 hours, whereas Viagra lasts for 4 to 6 hours.

It’s recommended to take Tadalafil at least 30 minutes before sexual activity. 

You might hear or see people referring to Tadalafil as the ‘weekend’ pill. This is because the effects of Tadalafil can last up to 36 hours, giving you help with getting an erection across a 2.5-day period. Taken on a Friday afternoon/evening the medication could take effect for the whole weekend, hence the nickname Tadalafil weekend pill. 

Tadalafil has various alternatives. Comparable medications, such as Viagra, Levitra, and Spedra, are prescription drugs that function similarly. Devices like penis pumps can also aid in addressing erectile dysfunction and can be utilised in conjunction with medications. Lifestyle adjustments, like regular exercise or smoking cessation, are found to be beneficial for some men in overcoming erectile dysfunction and addressing common underlying factors such as anxiety. 

Under no circumstances should Tadalafil be taken concurrently with another erectile dysfunction medication. The combination of these medications, working in the same manner, poses a serious risk of severe side effects and potential overdose. It is crucial to strictly avoid simultaneously taking Tadalafil and any other medicine for erectile dysfunction.     

 

Tadalafil is presented in tablet form and is recommended to be taken at least 30 minutes before expected sexual activity. It provides four dosage options, including two daily doses (2.5mg and 5mg) and two taken before sexual activity (10mg and 20mg). Opting for daily doses might be the preferred choice for individuals involved in sexual activity on more than three different days a week. 


Tadalafil can lower blood pressure and is sometimes used to treat pulmonary hypertension. It’s recommended that you don’t take tadalafil if you have low blood pressure or take medicines that can already lower blood pressure.

Tadalafil is the generic form of Cialis. Both medicines, have the same ingredients, effectiveness and side effects.

Sildenafil and tadalafil are both erectile dysfunction treatments - it can’t be said that one is ‘better’ than the other as personal reaction and preferences will determine if one treatment is more suitable for a patient than the other.
