Just a few questions from our Pharmacist before you checkout to make sure this medicine is safe for you.

What is Viagra Connect?
Viagra Connect is an aid to treat erectile dysfunction. It is the first treatment for erectile dysfunction that does not require a prescription and can be purchased over-the-counter.
What is the difference between Viagra and Viagra Connect?
Both Viagra Connect and the more familiar medicine Viagra work in the same way and contain the same active ingredient; sildenafil citrate.
Just like Viagra, this medication is indicated for the treatment of erectile dysfunction (impotence) in adult men. It works by relaxing the blood vessels, enabling more blood to flow into the penis, making it easier to get an erection.
Please note, this treatment only works if you are sexually aroused. It does not cause an erection without stimulation.
Is Viagra Connect right for me?
This treatment may be right for you as long as you are not taking any medicines that may interact with Viagra, or suffer from any health conditions that may affect its suitability.
Talk to your doctor about alternative treatments and do not take this medicine if any of the following applies to you:
- If you are allergic or sensitive to sildenafil or any of the other ingredients listed on the pack.
- If you are taking any medicines known as nitrates (including “poppers”).
- If you are currently taking any medicine (guanylate cyclase stimulators, such as riociguat) to treat high blood pressure in the lungs.
- If you are currently taking ritonavir (to treat HIV).
- If you have ever had a loss of vision due to optic nerve damage or inherited eye disease, such as retinitis pigmentosa.
- If you have low blood pressure.
- If you have problems with your liver, heart or blood vessels.
- If you have a deformity of your penis, such as Peyronie’s Disease.
This medicine is also not suitable if you are younger than 18. You should only use this treatment if you suffer from erection problems.

Is sildenafil the same as Viagra, Eropid and other brands?
Sildenafil is an active ingredient used in many erectile dysfunction medications.
It’s the main active ingredient in Viagra, Eropid, Liberize, and Aronix ED tablets, to name but a few.
This means that these medications all work to treat your condition in the same way.
What dose of sildenafil do I need?
Three doses of sildenafil are commonly available: 25mg, 50mg, and 100mg.
The recommended starting dose is 50mg, which is available in both prescription and over-the-counter treatments.
If you find that this dose is not effective, we recommend speaking to your doctor or prescriber to see whether they would recommend a different dose for you.
How do you take sildenafil tablets?
Take one sildenafil tablet around one hour before you plan to have sex.
Swallow the tablet whole with some water.
Do not take sildenafil more than once a day.
Who should not take sildenafil?
Sildenafil may be unsuitable for certain people. Do not take these tablets if you are allergic to any of the ingredients or if:
- You have severe heart problems
- You have severe liver problems
- You have recently had a stroke or heart attack
- You have low blood pressure
- You have certain, rare inherited eye diseases, e.g. retinitis pigmentosa
- You have ever had a loss of vision due to non-arteritic anterior ischemic optic neuropathy (NAION)

What are the side effects of sildenafil?

- Nausea
- Facial flushing
- Hot flushes
- Indigestion
- A colour tinge in your vision
- Blurred vision
- Visual disturbances

Can I buy sildenafil online?
You can buy sildenafil online from pharmacies like ours.
You’ll still need to follow all of the procedures you would when buying sildenafil in a high street pharmacy, but you can do everything from the privacy of your own home.
#Perfect for those who find talking about erectile dysfunction in a pharmacy a little embarrassing.
Is sildenafil incompatible with any medications (contraindications)?
Sildenafil can interact with some medications, causing some contraindications, so if you’re already taking other medications make sure to speak to your doctor or pharmacist before taking these tablets.
Some medications that can’t be taken at the same time as sildenafil include:
- Nitrate medicines or nitric oxide donors, which are often used to ease chest pain or heart failure, e.g. glycerine trinitrate, isosorbide mononitrate, isosorbide dinitrate, amyl nitrate (“poppers”), nicorandil, sodium nitroprusside
- Riociguat or other medicines from the group called guanylate cyclase stimulators, which are used to treat high blood pressure in your lungs, including that caused by blood clots
- Ritonavir, which is used to treat HIV
- Other erectile dysfunction treatments
- Alpha-blockers, which are used to treat urinary problems caused by an enlarged prostate or high blood pressure, e.g. alfuzosin, doxazosin, tamsulosin
- Protease inhibitors, which are used to treat HIV, e.g. saquinavir
- Cimetidine, which is used for heartburn
- Itraconazole and ketoconazole, which are used for fungal infections
- Erythromycin, which is an antibiotic
Why can’t I drink grapefruit juice when I’m taking Sildenafil?
You should not eat grapefruit or drink grapefruit juice while taking sildenafil, as they can affect your medication.
This is because they contain a kind of chemical called furanocoumarins.
This chemical reacts with an enzyme in the lining of your gut and liver which breaks down lots of different kinds of medications, making it less effective.
This means that if you eat grapefruit or drink grapefruit juice when taking a medication that needs this enzyme to break down, the enzyme won’t be able to do its job properly.
This can lead to too much of the medication you’re taking ending up in your bloodstream, giving you a much higher dosage than you needed to take and possibly causing side effects.
