Cialis is a prescription-only medicine for men, aged 18 or over, experiencing symptoms of erectile dysfunction. It comes in the form of a tablet which is taken orally, & can allow you to achieve & maintain an erection hard enough for sexual activity. You’ll need to be sexually stimulated for it to work.



How does Cialis work?


Tadalafil, the active ingredient in Cialis, is a PDE-5 inhibitor. Tadalafil can help to relax the blood vessels in the penis, resulting in increased blood flow and allowing for a man to get an erection.


It works in a similar way to other erectile dysfunction oral medicines.


Cialis is not an aphrodisiac; it can’t increase sexual pleasure or delay orgasm. It won’t work if you aren’t sexually stimulated, so you and your partner will still need to engage in foreplay as you would normally before sex. 



Who is Cialis suitable for?


Cialis is intended for use by adult men with erectile dysfunction. It is not suitable for anyone under the age of 18 or women. 


You should not take Cialis if you are allergic to tadalafil or any of the other ingredients in Cialis or if you are taking any form of ‘nitrates’ – these are used in the treatment of chest pain.


Before prescribing you Cialis, an online clinician or a GP will always check to make sure that the medicine is suitable for you. Conditions such as heart problems, liver or kidney problems or a deformation of the penis are some reasons why you may not be prescribed Cialis.


Some medication may also interact with Cialis or affect how well it works. Please read the patient information leaflet (2.5mg/5mg and 10mg/20mg), for a full list of who Cialis isn’t suitable for. 



How do I access Cialis?


Cialis is available through our Erectile Dysfunction Online Clinic, which allows you access to a number of prescription-only oral treatments for ED without needing to see your GP. No matter which ED medicine you are considering, you’ll need to complete an online consultation so that one of our clinicians can see if it’s suitable for you. If the treatment is suitable, you’ll then be able to pick it up from your chosen participating Boots pharmacy or have it delivered to you for free (subject to availability and clinician approval. Charges apply).


If you have erection problems it is important to speak to your doctor to discuss your symptoms. Erectile dysfunction can sometimes be caused by an underlying health condition so it’s important that your GP can rule out any conditions that may be causing your erection problems.



Is there a generic unbranded version of Cialis in your online clinic


Tadalafil is the active ingredient in Cialis and is also available as generic tadalafil. Our Erectile Dysfunction Online Clinic prices for generic Tadalafil start at £24.00, while prices for Cialis start at £38.00. All of our ED treatments are subject to online consultation, clinician approval and stock availability.    



How do I take Cialis?


Cialis is available in the following strengths: 2.5mg, 5mg, 10mg and 20mg.


Cialis 2.5mg & 5mg


Cialis 2.5mg and 5mg are taken daily. They are better suited for men who anticipate having more frequent sexual activity of at least twice weekly. This may support more sexual spontaneity, as when taken once daily Cialis 2.5mg and 5mg allows you to obtain an erection, when sexually stimulated, at any time point during the 24 hours of the day. The recommended starting dose is 5mg taken daily at around the same time each day. Cialis 2.5mg may be suitable for those who have experienced side effects with the 5mg starter dose. No matter what strength you have been prescribed, only ever take one tablet of Cialis in a 24-hour period.


Cialis 10mg & 20mg


Cialis 10mg and 20mg are taken when required at least 30 minutes before you intend to have sex. These strengths are not intended for daily use and you should not take more than once a day. Cialis at these doses can be effective for up to 36 hours from taking the tablet. The standard starting dose is 10mg. The 20mg dose may be considered for men who find that the 10mg dose is not working for them as they would have hoped. 


You should take the tablet whole with water, with or without food. It’s recommended that you avoid drinking excessive amounts of alcohol while taking Cialis, as this may affect your ability to obtain an erection.


If you take more than the recommended dose, contact your GP or call 111 immediately.



What are the possible side effects of taking Cialis?


As with all medicines, there can be potential side effects to taking Cialis. While not everyone will experience them, there is a risk of the following:


Common side effects

•    headache
•    back pain
•    muscle aches
•    facial flushing
•    indigestion


Uncommon side effects
•    dizziness
•    nausea and vomiting
•    stomach ache
•    fast heart rate
•    changes in blood pressure


Rare side effects
•    fainting
•    seizures
•    hives
•    sweating


If you experience any of the following symptoms, you should stop taking Cialis immediately and seek medical help or advice as soon as possible:


•    chest pains

•    allergic reactions including rashes
•    sudden loss of vision
•    priapism (a prolonged and painful erection) – if you experience an erection that lasts continuously for more than four hours seek medical attention immediately


For a full list of side effects please see the patient information leaflet (2.5mg/5mg and 10mg/20mg). 



What if Cialis doesn’t work for me?


Cialis may not start to work for you the first time you try it. If it’s not working as you would have liked after eight different attempts, you may consider moving onto a higher strength (if suitable for you) or trying a different oral ED medicine. Our Erectile Dysfunction Online Clinic offers a number of oral ED treatments, including Sildenafil, Spedra and Levitra. All are subject to an online consultation and clinician approval. We also offer generic Tadalafil, but – as that is the same active ingredient as Cialis – it’s unlikely to work if Cialis didn’t.


There’s also a number of other ways you can treat ED without oral drugs.
