Choosing the right Cialis dose for erectile dysfunction is all about finding what works best for you and your needs. It comes in 4 different strengths, and the best dosage depends on how often you plan to use it and how your body responds to the medication, which will vary for everyone.
Find out how to choose the right strength of Cialis for you and how often you can take it.
You can get Cialis in four different doses in th UK:
The dose of Cialis refers to how much of the active ingredient ‘tadalafil’ is in them. The lower doses (2.5mg and 5mg) are usually prescribed for ‘daily’ use, while the higher two doses (10mg and 20mg) can be taken as required or ‘on demand’. This means you take them at least 30mins before you plan to have sex, instead of taking them at the same time every day.
5mg is the standard dose for Cialis Daily, and 10mg is the standard dose for on demand Cialis.
The maximum dose of tadalafil for erectile dysfunction in the UK is 20mg, and higher doses are currently only available in the US. Higher doses of Cialis have an increased risk of side effects, because blood pressure is affected and the amount of Cialis in your body can build up over time.
40mg of tadalafil is used in some situations to treat pulmonary arterial hypertension, but only under specialist supervision because of the risks.
"Cialis is available in four dosages. While the lower doses of 2.5mg and 5mg can be taken daily, the 10mg and 20mg doses are to be taken when needed."
If you have sex on up to three different days a week, and you’ve never tried Cialis before, this is usually the first dose of Cialis that’s recommended. It’s known as the ‘standard dose’:
If you tried Cialis 10mg and didn’t see the desired effect (but also didn’t experience any negative side effects), you can try upping the dose to 20mg.
If you have sex on more than three different days in a week, taking Cialis Daily might be a good idea. This comes in 2 doses like Cialis on demand, but the higher dose of 5mg is the standard one.

All doses can be taken up to once a day. You should never take more than one Cialis tablet every 24 hours.
Think about switching to Cialis Daily if:
If 20mg of Cialis doesn’t work for you, you may have to try a different medication. Or, you could try combining Cialis with some other treatments like lifestyle changes, counselling, penis pumps, or therapy. You should never combine Cialis with any other erectile dysfunction medication, or take more than the recommended daily dosage.
Cialis and Viagra have different active ingredients in them that make them work. So, the doses of Cialis and Viagra are not related and you can’t compare the number of mg to figure out which might be more effective (e.g. 20mg of Viagra wouldn’t be the same as 20mg of Cialis).
