Viagra, which is often called the little blue pill, is a treatment for erectile dysfunction or impotence that will help you to get things going when you’re enjoying some alone time with your partner. If you struggle to get or maintain an erection, Viagra could be the treatment for you, as it helps you to get hard and stay hard, so you and your partner can enjoy your most intimate moments together.
How Viagra works
Viagra contains an active ingredient called sildenafil, which is one of a group of medicines called phosphodiesterase type 5 (PDE 5) inhibitors. It relaxes the blood vessels in your penis, making it easier for your blood to flow where it needs to for you to get an erection. It only gets to work when you’re sexually stimulated, so take it around an hour before you’re planning on having sex to make sure you’re prepared to get it up and get down to business.

Sildenafil is an active ingredient used in many erectile dysfunction medications.

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.

- Facial flushing
- Hot flushes

What is the difference between tadalafil and sildenafil (Viagra)?
Sildenafil is the active ingredient in the popular erectile dysfunction treatment, Viagra, and many men use it to manage their condition.
The biggest difference between sildenafil and the tadalafil in this product is that you will need to know when you’re planning on having sex when you’re taking sildenafil, as you need to take your tablet around an hour before you get down to business.
This can sometimes ruin the mood if you’re the more spontaneous type and could cause problems if you’re out and about and forget to bring a tablet with you for when the mood strikes.
On the other hand, tadalafil is taken once a day, at the same time every day, and will work to help you get an erection at any time, day or night.
However, there is one more thing to consider, and that is how you will get hold of your treatment.
Tadalafil tablets need a prescription from a medical professional before you can get them, whereas sildenafil can be bought over the counter after a quick chat with a pharmacist.
If you’re unsure which would be best for you, we recommend talking it over with your doctor, they can help to point you in the right direction.
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.
