What our patients say

What is Cialis?

How to take Cialis

Take one tablet at least 30mins before sex. Effects can last for up to 36hrs. Never take more than one tablet within 36hrs. Alcohol will limit Cialis’ effectiveness. Do not combine Cialis with other ED medicines.

How does Cialis work

Cialis’ active ingredient (tadalafil) increases blood flow to the penis. It enables a firmer, longer-lasting erection if you are sexually aroused.

The treatment will not resolve the underlying physical cause of your ED or increase your sexual desire.

What are the negative side effects of Cialis?

Cialis side effects are uncommon, but can include headaches, indigestion, palpitations (racing heartbeat), light headedness, facial flushing, nasal congestion and muscle aches. These side effects should not last more than a few hours after taking a dose of Cialis.

For full information on side effects and correct use, see the patient information leaflet.

When to take Cialis for best results

Cialis treats ED in 80% of cases. If you have drunk more than 1-2 units of alcohol, you may find Cialis is less effective. Food does not impact how Cialis works.

We advise trying an ED treatment 8 times before giving up, considering a higher dose, or seeking an alternative.

What is the best dosage for Cialis?

The standard dose is 10mg. Depending on your age, height and weight, the cause and the severity of your ED, you may be prescribed a higher dose of 20mg. Dosage does not affect how quickly or for how long the treatment works.

Higher doses come with an increased chance of developing side effects.

What should you not take with Cialis?

You will be unsuitable for Cialis if you are taking alpha-blockers (such as doxazosin or tamsulosin), nicorandil or nitrates, such as GTN spray or isosorbide mononitrate tablets to treat angina.

It is important that you let us know which prescription, over-the-counter medicines and recreational drugs you are taking so that we can prescribe Cialis safely.

Alternative treatments

Some men find counselling helpful as a means of exploring and treating psychological causes for ED.

If Cialis does not work for you, contact us via your Patient Record so that we can discuss your treatment options. View all our ED treatments.
