About Cialis

The weekend pill

Cialis from Lilly pharmaceutical company is sometimes known as The Weekend Pill due to its 36-hour duration of action.

It has been licensed in the UK since 2003. It was the second erectile dysfunction (ED ) prescription medication of its type to receive a UK license, after Viagra (sildenafil). Its prolonged effectiveness and the option to take a low dose daily tablet have led to Cialis becoming increasingly popular and being more widely prescribed.

Generic Cialis

The patent for Cialis expired in the UK on 14 November 2017, allowing other drug manufacturers to legally make and sell generic versions (marketed as tadalafil). Generic medicines are medically identical to branded originals and are usually much lower cost.

Daily versus Cialis ’36 hours’

Most men take Cialis as and when they need it, usually 10mg or 20mg, which is effective for up to 36 hours.

Men who need erectile dysfunction treatment two or more times a week should consider taking a regular low dose tablet daily. 2.5mg or 5mg strength tablets taken every day will provide continuous erectile dysfunction treatment, without peaks and troughs.

What does it do?

Tadalafil can also be used to treat benign prostatic hyperplasia (enlarged prostate) symptoms.

Why do men get erectile dysfunction?

A range of factors contribute to erectile dysfunction, including lifestyle choices, mental state, chronic disease, and injuries and operations. Emotional problems, such as stress and performance anxiety, can have an impact on both erectile performance and sexual desire. Occasional treatment with a PDE5 inhibitor such as Cialis can be effective in breaking a cycle of anxiety and failure. Lifestyle factors, such as smoking, non-prescription drug use, excessive drinking, and even obesity can have an effect. Erectile dysfunction is sometimes a symptom of underlying health problems such as diabetes, atherosclerosis, and heart disease, amongst others.

Why Cialis?

Cialis benefits from having a long duration of action. Viagra remains active for about 4 hours, Levitra for 4-5 hours, and Cialis for 36 hours – hence its familiar name ‘The Weekend Pill’. Erections will not be continuous during 36 hours after taking Cialis, occurring only at times of arousal during those 36 hours.

Alternative treatment

Viagra (sildenafil), Levitra (vardenafil), and Spedra (avanafil) are alternative tablet treatments for erectile dysfunction and are also available to buy in various strengths and pack sizes after completing the same medical consultation.

Taking Cialis for the first time

There are four strengths – 2.5mg, 5mg, 10mg and 20mg. The lower doses of 2.5mg and 5mg are primarily for regular daily use, although the 5mg strength can be taken on an as required basis by men who respond well to one-off lower doses.

The usual starting dose is 10mg taken at least 30 minutes before sexual activity. If this dose is highly effective, subsequent doses could be reduced to 5mg on a trial basis. If repeated trials of a 10mg dose prove ineffective, the dose can be increased to 20mg.

There is no benefit in taking a higher dose than is needed. Repeated trials of treatment at one dose are recommended before changing to higher or lower strength tablets.


Daily Cialis

2.5mg or 5mg daily tablet for continuous erectile dysfunction treatment.

Cialis 10mg

Recommended starting dose for most men taking for first time.

Cialis 20mg

High strength dose as required for when 10mg is insufficient.

Does it work every time?

Response to treatment is usually predictable and consistent. On most occasions, if Cialis has worked before, it will work again.

Some causes of erectile dysfunction, such as physical injuries or nerve damage, are more resistant to tablet treatments and may require other therapies, such as injections or penile implants.

Erectile dysfunction may require specialist treatment apart from tablets. Some men, whose erectile dysfunction has psychological causes, may benefit from counselling.

All men who are troubled by erectile dysfunction, which can be a distressing problem, should consult a doctor for a full assessment and advice.

Side effects of Cialis

Most men do not experience significant side effects. A full list of the most frequent side effects can be found in the manufacturer’s patient information leaflet supplied with tablets (links below).

Some men experience a bluish or yellowish tinge to their vision after taking Cialis. This is not dangerous and fades after a few hours time. This is a possible side effect of all ED drugs (PDE5 inhibitors).

Other common side effects (affecting 1%-10%) include headache, back pain, muscle aches, pain in the arms or legs, nasal congestion, facial flushing, and indigestion.

On very rare occasions ED treatment produces prolonged and painful erections, in a condition known as priapism. Priapism is a medical emergency with the potential on rare occasions for irreversible injury to the penis. If an erection lasts for more than 2 hours, medical attention should be sought immediately.

When not to take Cialis

Cialis should not be taken at the same time or within 36 hours of taking Viagra/sildenafil, Levitra/vardenafil, or Spedra/avanafil.

Patient leaflet

The ‘Patient Information Leaflet’ supplied with medication must be read before taking tablets.

Cialis FAQs

Why should I see a doctor face-to-face before starting ED treatment?

Is Cialis suitable for all men?

What is the difference between Cialis and Viagra?

Why is Cialis sometimes called the ‘weekend pill’?

A 10mg or 20mg tablet taken on Friday evening will usually remain active through a whole weekend until Sunday morning, hence the name.

Why do some men take Cialis every day?

Most men take it occasionally, up to a maximum of 2 or 3 tablets per week. They take a tablet if they expect to be sexually active in the following 36 hours. Men who regularly require Cialis more than twice a week sometimes prefer to take a lower dose 2.5mg or 5mg tablet each day, at the same time of day. These low dose tablets are specifically for daily use and provide a continuous level of treatment.

Is Cialis stronger than Viagra and Levitra?

No, the duration of action is longer, 36 hours for Cialis compared with 4-5 hours for Levitra and 4 hours for Viagra, however most men find that during this active period the treatments are equally effective when equivalent strength tablets are used. The lower strength of each is Cialis 10mg, Levitra 5mg, and Viagra 25mg and the upper doses 20mg, 20mg, and 100mg respectively. Some men find one type of tablet works better for them than another, but this is not usually the case.

Is there a lower cost generic version of Cialis?

Yes. Cialis was under patent by the drug company which developed it, Eli Lilly until 14 November 2017. Dr Fox can now offer UK licensed generic tadalafil at significantly lower cost.

Who can legally supply Cialis in the UK ?

Only registered pharmacies are allowed to supply Cialis. It is a prescription only medicine. In most cases doctors write the prescriptions and pharmacies dispense the tablets. Some specialist pharmacists can also prescribe or supply it using a ‘patient group direction’. In all cases only registered pharmacies can supply it.

Why do the prices of Cialis vary?

The amount pharmacies pay is the wholesale price set by the drug company Eli Lilly. The amount pharmacies charge patients will depend on their business models. Some supply it with a small profit margin and others with bigger profit margins. It is usually worth shopping around for the lowest cost supplier, but always use a registered pharmacy to avoid fake medicines.

Can I get Cialis on the NHS ?

Can I get Cialis on a private prescription from my doctor?

Can Cialis tablets be div >

No, Cialis tablets are film coated and are intended to be swallowed whole. Cutting up the tablets will reduce their effectiveness.

Why should Cialis not be taken with recreational or illegal drugs?

People who take illegal drugs are likely to engage in risky sexual practices and this likelihood is increased when ED treatments are taken at the same time. There is also an increase in side effects, such as changes in vision and changes in blood pressure. Combined with cocaine and other recreational drugs may lead to the rare but dangerous condition of priapism in which a prolonged erection of more than an hour or two can cause permanent damage to the erectile tissues. See Beware club drugs and Viagra.

Is ED counselling better than tablets?
