NOTE: After selecting this product, you will need to complete a short assessment, so we can make sure this medication is suitable for you. Pricing is provided as a reference only. The final decision on issuing this medication remains with our Prescriber / Pharmacist.

Tadalafil, sold under the brand name Cialis, is a drug used to help increase the flow of blood to the penis in men who have difficulty getting, or maintaining an erection, following sexual arousal.

Available in 2.5mg or 5mg as a daily tablet or 10mg or 20mg when required. Speak to our team for discreet, confidential advice. 


  • How long does Tadalafil take to work? How long will it last?

    Tadalafil starts to work around 30-45minutes; however, it can produce an effect anywhere between 20 to 60 minutes after being taken.

    Tadalafil will be effective up to 36 hours after taking the tablet; however, this does not mean that you will have an erection for the duration of this time. Sexual stimulation is also needed to achieve an erection whilst taking Tadalafil.

    The time it takes to work and produce the desired effects can be influenced by other factors such including food and alcohol. Consuming Tadalafil with a high-fat meal or a high amount of alcohol will delay how long it takes for Tadalafil to work and may be less effective.

  • How regularly can I take Tadalafil tablets?

    Although Tadalafil can typically be taken as often as it is required, it is recommended not to take more than one erectile dysfunction medication treatment in 24 hours.

  • Can I take Tadalafil if I have heart problems?

    Tadalafil should always be used in caution in men with heart problems. Tadalafil can put the heart under increased strain by causing the blood vessels that supply the heart to widen, which results in increased blood flow into the heart.

    Whether Tadalafil is suitable or not will depend on a number of individual circumstances and your symptoms as well as their severity.

    You should speak to a GP or a member of our team before proceeding.

  • Can I take Tadalafil even if I don’t have ED?

    Tadalafil should only be taken if you are experiencing erectile dysfunction. It should not be taken for the purpose of sexual enhancement.

Side Effects

There is always a risk of side effects with all medications. Some of these can be quite mild and can subside over time. Others are more serious and should be reported to your GP right away if you experience any side effects. Please contact a member of our team if you are concerned about any potential side effects that may occur when taking Tadalafil.

Common side effects may include:

  • Nosebleeds
  • Dizziness
  • Nausea
  • Flushing
  • Headaches
  • Runny/stuffed nose
  • Red and/or warm skin
  • Diarrhoea
  • Muscle pain or back pain

The side effects listed below are of a serious nature; you should stop taking Tadalafil, and report these to your GP immediately.

  • Sudden vision loss in both eyes or one eye. Sudden vision loss in both eyes or one eye can be a sign of a serious eye problem called non-arteritic anterior ischemic optic neuropathy.
  • An erection that will not go away (priapism). If you have an erection that lasts more than 4 hours, get medical help immediately. Priapism can cause permanent damage to your penis.
  • Sudden hearing decrease or hearing loss. Some men may also have ringing in their ears (tinnitus) or dizziness.
