Can I buy Cialis online?
Cialis is a prescription-only medication, which can be safely and legally prescribed online by services like Superdrug Online Doctor. Any online pharmacy which is prepared to sell Cialis without a prescription is operating illegally, and could potentially be selling fake or dangerous medication.If you’re buying Cialis online, make sure the site you’re buying from is regulated by the Care Quality Commission and Medicines and Healthcare products Regulatory Agency. These organisations make sure that it is safe for these sites to prescribe and sell medication online.
Can I buy Cialis over the counter?
You cannot buy Cialis over the counter. Cialis is a prescription-only medication, which means that you can only get it after you have completed an assessment with a doctor and they think it is safe and appropriate for you to take it. Viagra Connect is the only erectile dysfunction medication that is available over the counter.

Buying generic Cialis
You can buy a cheaper, generic version of Cialis, called Tadalafil. Cialis is a branded medication, which means that it is more expensive than Tadalafil as you are paying for the brand name.
Tadalafil is the name of the active ingredient in Cialis and both generic Tadalafil and Cialis work in the same way. They have the same:
- effectiveness
- dosages
- daily and before sex options
- chance of side effects
- safety information
Cialis is:
- a long-lasting erectile dysfunction medication used to help you get and stay hard
- a prescription-only medication, so a doctor has to approve it for you
- safe and effective as long as a doctor approves it for you
How Cialis works
Cialis works in a similar way to other erectile dysfunction treatments. It relaxes muscles around your penis, improving blood flow and making it easier to get and keep erections when you’re aroused.
If taken before sex, Cialis:
- starts working in about 30 mins
- lasts for up to 36 hours
- might not work as well if you drink alcohol or eat a heavy meal beforehand
If you take Cialis Daily, you do not need to plan to take it before sex. Cialis Daily is always working, and helps you get an erection whenever you’re ready to have sex.
How to take Cialis
Taking Cialis is easy, just like any other tablet you swallow:
- For Cialis 10mg and 20mg – take your tablet 1 hour before you want to have sex, and avoid heavy meals before you take it
- For Cialis Daily – take your tablet at the same time every day
- Swallow your tablet whole, with water if needed
- Don’t take more than 1 tablet every 24 hours
- Avoid drinking alcohol to get the best results and less risk of side effects
What are the dosages of Cialis?
There are 4 dosages of Cialis. 2 daily doses and 2 doses taken before sex. Daily doses can be a better choice if you have sex on more than 3 different days a week.
Cialis 2.5mg:
- The lower-strength daily dose
- You can try this dose if you’ve tried 5mg and it worked well but it gives you some mild side effects
- Daily doses
Cialis 5mg:
- The standard daily dose
- This is the recommended dose if you’ve not tried Cialis Daily before
Cialis 10mg:
- The standard before sex dose
- This is the recommended dose if you’ve not tried Cialis before
Cialis 20mg:
- The higher-strength before sex dose
- You could try this dose if 10mg does not work for you and you don’t get any serious side effects
Make sure to check with a doctor before switching the dose of any medication.
See our Cialis Dosages page for more information.
Cialis is an effective treatment, but it doesn’t work for everyone:
- It works for 60-70% of people who try it
- Cialis has a rating of 8.7 out of 10 for erectile dysfunction treatment according to user reviews on drugs.com
- On average, patients who used Superdrug Online Doctor to order Cialis treatment rate it 4.6 out of 5 stars on Trustpilot.com
Not sure if Cialis is right for you?
There are a lot of different ways to treat erectile dysfunction. You may find these other pages useful:
Cialis can cause some side effects and it may react with other medication you’re taking. For full safety information, please read the patient information leaflet that comes with your medication – Cialis taken before sex PIL, Cialis Daily PIL.
Cialis side effects
Less than 2% of people appear to get side effects when taking Cialis 10mg. If you think you’re having side effects, talk to your regular doctor.
Common side effects of Cialis are:
- headache
- stuffy or runny nose
- flushing
- indigestion
- muscle aches
Uncommon side effects of Cialis are:
- increased heart rate
- changes in blood pressure
- blood in the urine
- ringing in the ears
- palpitations
- erection that won't go away (priapism)
- blurred vision
- eye pains
- increased sweating
- difficulty breathing
- nose bleeds
- dizziness
- nausea, being sick or abdominal pain
- a rash
- chest pain
- tiredness
If you suffer from severe side effects such as:
- visual loss
- chest pain
- a prolonged, painful erection
- a seizure
you should always see a doctor immediately and stop taking Cialis.
If your side effects become serious and/or are impacting your life too much for you to want to continue taking Cialis, then you should stop taking it and discuss it with your doctor.
You shouldn't just adjust or switch your treatment without medical advice as everyone's body reacts slightly differently to medications.
Drug interactions

- nitrates, e.g. isosorbide mononitrate, glyceryl trinitrate

- antifungals, e.g. ketoconazole and itraconazole
- antivirals, e.g. ritonavir and saquinavir
- alpha-blockers, e.g. tamsulosin, doxazosin, alfuzosin
- other erectile dysfunction medications, e.g. Viagra, Levitra etc
Alcohol and grapefruit juice can react with your medication too.
Pre-existing conditions
You may not be able to take Cialis if you have:
- Peyronie's disease (a condition that causes the penis to curve)
- heart problems or have had a stroke
- certain visual/ eye conditions
- kidney or liver disease
- sickle cell anaemia, multiple myeloma or leukaemia

Worked well but took a bit longer than I expected to work and I had pains in my leg joints and hips for a few days afterwards which made it difficult to sleep and sit down,seemed better whenI was walking.
-
Very simple and speedy service. They delivered what was asked.
-
Useful service which was easy to use.
-
Very impressive service - quick prescription and delivery. Faultless! Thank you.
-
Quick, easy and highly efficient service.
-
Ordered a prescription only medicine, completed a few common sense questions so their doctor could issue the prescription and received the medication in the post within two days. Perfect solution. The alternative would have been to wait for weeks for a doctors appointment, take time off work etc etc. Yes, it costs more than NHS but if you've got the money and time is the main thing you haven't got then it makes complete sense to use this service.
-
I will continue to use it. I suspect I will learn to use it more effectively with practice.
-
The service provided was very accurate and the delivery was on time.
-
Was effective for me. Noticed the difference immediately.
-
Still haven't recovered my order and it has been over a week already and seems that my order has been lost

Easy to order and collect.
-
Excellent service from Superdrug, Fast efficient and discrete. Thank you

It was just right I could see my and feel my confidence building

Effective for my condition. It helps to relax me and not to focus too much on 'performance'.
-
Wow! Life affirming. Such an improvement my girlfriend noticed immediately and it may be transformational for us. Being able to order online in this way has also been an enormous help to me, and ensured I did benefit from this. I will be re-ordering soon
-
Product is simple to take and very effective.
-
I bought some medication for treating erectile dysfunction from Superdrug.I got my medication on time. Will buy again from Superdrug.
-
Way to expensive. This restricted any further purchases I am afraid.
-
Bought this product as I had noticed on rare occasions my erection didn't stay as hard as it would normally. I reluctantly put this down to maybe gaining a little weight and probably age but I wanted to try and rectify the situation before it began to play on my mind. I looked into various products and although they are all very similar I decided to try this one. I have asked my partner to give her opinion of the product as she was involved too. She tells me that there was a noticeable increased hardness in my penis and that the hardness seemed to last. It also seemed to improve my erection for the following day.
-
The product helped fantastically very pleased with it
-
Service fine, very fast but could be better on price
-
feel as if I can use a slightly higher pill
-
It works, short time before it becomes effective, lasts 24 - 36 hours!
-
Very fast and efficient service. 5 stars
-
This is the first time I've tried any 'help'. I took a single dose of 20mg, and the results were all I had hoped for. No embarrassing hardness before arousal, then really strong erection whenever needed, and over a 48 hour period. And no hint of side effects, even though I was looking for them. Hoping it might just have given my system a reminder, but if needed in future, I will consult on whether a small daily dose is better than the occasional 20mg. The Superdrug service was really efficient and totally discreet. Thank you!!!
-
Product as expected the service provided was excellent and I will use again.
-
Product works well with no obvious side effects.
