Order Sildenafil Online
You can request to buy Sildenafil online in the UK without a prescription, from our registered online pharmacy and doctor service. Sildenafil tablets are a treatment for erectile dysfunction in men.
As this medication requires a prescription, you will need to complete an online assessment. Once you have completed your order, our UK registered and trained GP's will review your assessment. If approved, a prescription will be issued which is passed on to our UK registered online pharmacy. The pharmacy team will dispense your order, and dispatch the medication to your chosen delivery address.
What Are Sildenafil Tablets?
Sildenafil is a drug used for erectile dysfunction in men. It is the generic form of the well-known drug, Viagra. The patent for Viagra expired in 2013, which allowed manufacturers other than Pfizer to make the medication. This, in turn, drove down the price of the active ingredient, Sildenafil. Sildenafil is a popular choice of treatment for erectile dysfunction, as medically there is no difference between Sildenafil and its branded alternative, yet Sildenafil is a much more affordable option.
How it works
Sildenafil is from a class of drug called PDE inhibitors. Men who suffer from ED are unable to pump enough blood into the penis to achieve a hard enough erection. Sildenafil helps men achieve a harder and longer-lasting erection, by stimulating blood flow to the penis, resulting in longer and harder erections for men who struggle.
Strengths of Sildenafil Tablet
Strength | Use | Price |
Sildenafil 25mg | Typically used for men who have found that 50mg is too strong, and resulted in an erection which was harder or more longer-lasting than required. | From 78p / Tablet |
Sildenafil 50mg | Sildenafil 50mg tablets is usually the recommended starting dosage. Most men will find this delivers the desired response, and an erection sufficient for intercourse will be achieved. | From £1.01 / Tablet |
Sildenafil 100mg | The 100mg dosage is reserved for men who have not responded to the 50mg strength. You shouldn't start treatment at 100mg, as this can potentially lead to an erection that lasts too long or becomes painful. | From £1.43 / Tablet |

How to take Sildenafil
The typical starting dose for Sildenafil is ONE 50mg tablet 30 minutes before sexual activity. Most men will find this dose effective, however, if 50mg is too strong, you may wish to half the tablet the next time you are taking the medication. If successful, a 25mg tablet may be more suitable for your next prescription.
If the 50mg does not achieve the desired result, you should try the same dose 2-3 more times, to see if you can achieve a satisfactory erection. If this is not successful, you can increase your dosage to 100mg. If a 100mg dose is also ineffective, speak to us about the next steps. Sildenafil should not be taken more than once in 24 hours.
If you have already used a few erectile pills without success, a face to face referral may be required.
If you have not yet tried one of the other ED medications, you may find that Tadalafil or Vardenafil is effective for you.
Patients will find different drugs more effective. This does not necessarily mean one drug is more effective than another. It can be that your body responds slightly differently to a particular medication.

Strengths | Available strengths are 25mg, 50mg and 100mg. 50mg is the typical starting dose. |
Sildenafil Alternatives
Although Sildenafil provides the most affordable treatment, it may not always be best suited to your needs. Levitra (or Vardenafil) is the most suitable treatment for people who suffer from diabetes, while Cialis (or Tadalafil), provides a longer-lasting effect. There is also now an over the counter option of Sildenafil in the form of Viagra Connect. This contains Sildenafil 50mg.
Vitaros cream is another alternative to oral medications in treating erectile dysfunction. If you have difficulty swallowing tablets, Nipatra (chewable sildenafil), is available.
You can also look at counselling since some men suffer from erectile dysfunction as a result of nerves. If you think your ED is psychological, therapy may provide long term benefits if successful.
Comparisons of Sildenafil with other main ED medications are below.
Sildenafil vs Viagra
Sildenafil and Viagra are actually the same drugs. Each contains the active ingredient Sildenafil Citrate. The primary points of difference lie in cost and appearance. Sildenafil is significantly cheaper than its 'big brother' Viagra. Viagra is a branded version, manufactured by Pfizer. Its appearance is a trademarked diamond blue pill shape. Sildenafil is made by multiple different manufacturers, and its appearance can vary in colour and shape.
Each treatment has the same pharmaceutical properties. This means dosage, length of action and effectiveness are all the same.
Sildenafil vs Tadalafil
Sildenafil and Tadalafil are both erection pills, from the same family of drug, however, they have some differences. While Sildenafil is generally more cost-effective, Tadalafil can be longer-lasting. This can mean taking one tablet of Tadalafil on a Friday night, which could last you until Sunday night. What's best for you, may depend on how often you have sex. If you have sex several times per week, you may find a daily 5mg Tadalafil is most appropriate.
However, if you only have sex once a week, when required Sildenafil treatment might be best suited to your needs.
Sildenafil | Tadalafil | |
Duration of Action | 4-6 hours | Up to 72 hours |
Daily Tablet Available? | No | Yes |
Effectiveness | ~82% | ~81% |
Price | From 78p / Tab | From 67p / Tab |
Speed of Action | ~30-60 mins | ~30 mins |
Different Manufacturers
As Sildenafil is a generic medication, there are multiple manufacturers of the same drug. This means you may see differences in packaging and even the colour of the tablet from prescription to prescription. All manufacturers must meet MHRA standards, and so you can be confident the medication you receive contains exactly the same amount of active ingredients as any other.
In rare instances, some patients may notice one manufacturer is more suitable for them. This can be due to other ingredients in the medication such as colouring, which they may be allergic to. If you have noticed a particular manufacturer is better for you, please e-mail us after placing your order requesting which manufacturer you would like. We will then do our best to accommodate your request, or offer a refund if this is not possible.
Manufacturers of Sildenafil tablets in the UK include Teva, Mylan, Accord, Actavis, Dr Reddys, Sandoz and Zentiva amongst others.
Teva Sildenafil
Many men request Sildenafil by Teva from our pharmacy. It's difficult to obtain scientific data to demonstrate that Teva Sildenafil is any more effective than any other manufacturer. Often, trends towards a particular manufacturer of a drug can be driven by online discussion forums and boards. All medication sourced by our pharmacy is from MHRA regulated wholesalers and manufacturers. There should be no medical difference between manufacturers in terms of effectiveness.
Accord Sildenafil
Accord Sildenafil is another well-searched manufacturer of Sildenafil. We can accommodate requests for this particular version of Sildenafil. Just drop us a message after you place an order requesting Accord Sildenafil, and our pharmacy team will aim to provide this manufacturer. If for any reason we are unable to source a particular manufacturer, we will give you the option of a refund, or to proceed with another manufacturer.
Side Effects of Sildenafil
With any medication you take, there is always a risk of side effects occurring. Some are more common than others, and often side effects may subside with the regular usage of the medicine. If the side effects do not subside, you should report them to us, or your GP.
Common Side Effects
- Headaches
- Flushing
- Runny/stuffed nose
- Upset stomach
- Nausea
- Red and/or warm skin
- Dizziness
- Diarrhoea
- Nosebleeds
- Muscle pain / Back Pain
The side effects listed below are more serious, and you should stop taking Sildenafil, and report these to your GP immediately.
- An erection that will not go away (priapism). If you have an erection that lasts more than 4 hours, seek medical help immediately. Priapism can permanently damage your penis.
- Sudden vision loss in one or both eyes. Sudden vision loss in one or both eyes can be a sign of a serious eye problem called non-arteritic anterior ischemic optic neuropathy (NAION). Stop taking Sildenafil and call your healthcare provider right away if you have sudden vision loss in one or both eyes.
- Sudden hearing decrease or hearing loss. Some people may also have ringing in their ears (tinnitus) or dizziness. If you experience these symptoms, stop taking Sildenafil and contact a doctor right away.
For a full list of side effects, please read the patient information leaflet.
Sildenafil Dosage
For those who have never taken Sildenafil before, the typical dose is 50mg. This is taken 30-60 minutes before sexual activity.
If no effect is seen, the dosage can be adjusted up to a maximum of 100mg as a single dose in 24hours. If the effect was too strong, the dose can be reduced to 25mg. If you have not seen a response from Sildenafil, it is advised to try it at least 5 times before giving up.
Cautions
Alpha-blockers and Sildenafil
If you are taking alpha-blocking medicines, such as tamsulosin or trazodone, you are advised to leave at least six hours between taking your alpha-blocker and Sildenafil.
Nitrates and Sildenafil
Sildenafil cannot be prescribed by our doctor if you are taking nicorandil or nitrate-based medication, such as GTN spray or isosorbide mononitrate tablets for angina.
