Buy Sildenafil Online UK: 25mg, 50mg and 100mg ED Tablets

Sildenafil is a commonly used treatment for erectile dysfunction, also known as ED or erection problems. It is the active ingredient in Viagra and works by helping increase blood flow to the penis when you are sexually aroused.

At UsMen, you can request Sildenafil tablets online in the UK after completing a short medical questionnaire. A prescriber will review your answers to check whether Sildenafil is suitable for you, including the correct strength and quantity.

Quick answer: Sildenafil usually starts working within 30 to 60 minutes, can remain active for up to 4 hours, and should not be taken more than once in 24 hours. It only works when you are sexually stimulated.

Order Sildenafil online or complete an ED consultation to check suitability.

What are Sildenafil tablets?

Sildenafil tablets are used to treat erectile dysfunction in adult men. Erectile dysfunction means being unable to get or keep an erection firm enough for sexual activity.

Sildenafil belongs to a group of medicines called PDE5 inhibitors. Other ED treatments in this group include Tadalafil, Vardenafil and Spedra.

Sildenafil does not increase sexual desire. You still need sexual stimulation for it to work.

Is Sildenafil the same as Viagra?

Yes. Viagra is the branded version of Sildenafil. Both contain the same active ingredient, sildenafil citrate. Generic Sildenafil works in the same way as Viagra, but is usually available at a lower cost because it is not sold under the Viagra brand name.

Viagra, Viagra Connect and generic Sildenafil are all used for erection problems. The main differences are usually brand, price, packaging, available strengths and whether a prescription or pharmacist assessment is required.

How does Sildenafil work?

When you become sexually aroused, blood flow to the penis increases. Sildenafil helps relax blood vessels in the penis so blood can flow more easily, helping you achieve and maintain an erection.

It will not cause an automatic erection. You need to be sexually aroused for Sildenafil to work. Think of it like unlocking the door, not dragging you through it.

How long does Sildenafil take to work?

Sildenafil usually starts to work within 30 to 60 minutes. For some men it may take a little longer, especially after a heavy or high-fat meal.

For best results, take Sildenafil with water on an empty stomach or after a light meal. Avoid taking it after a large fatty meal if you want it to work as quickly as possible.

How long does Sildenafil last?

Sildenafil can remain active for up to 4 hours. This does not mean you will have an erection for 4 hours. It means the medicine may help you get an erection during that window if you are sexually stimulated.

If you want a longer-acting ED treatment, Tadalafil may be more suitable for some men, as it can last longer than Sildenafil.

How do I take Sildenafil tablets?

Always follow the instructions from your prescriber and read the patient information leaflet supplied with your medicine.

• Take one tablet 30 to 60 minutes before sex.
• Swallow the tablet with water.
• Do not take more than one Sildenafil tablet in 24 hours.
• Do not take Sildenafil with other ED tablets unless advised by a clinician.
• Sexual stimulation is needed for Sildenafil to work.

Taking more than the recommended dose will not make Sildenafil work better, but it can increase the risk of side effects.

Sildenafil 25mg, 50mg and 100mg: which strength is best?

Sildenafil is commonly available in 25mg, 50mg and 100mg tablets. The right strength depends on your response, side effects, age, medical history and other medicines you take.

If Sildenafil 50mg does not work the first time, do not automatically jump to 100mg. Sildenafil can fail if taken after a heavy meal, without enough stimulation, too soon before sex, or after drinking too much alcohol.

Can I buy Sildenafil 100mg online in the UK?

Yes, you can request Sildenafil 100mg online in the UK, but it must be clinically appropriate. You will need to complete a medical questionnaire so a prescriber can check your suitability.

Sildenafil 100mg is the highest commonly used strength for ED. It may increase the chance of side effects compared with lower strengths, so it is not automatically the best option for every man.

Can I eat or drink alcohol with Sildenafil?

You can take Sildenafil with or without food, but a heavy or fatty meal can delay how quickly it works.

Alcohol can make it harder to get an erection and may increase the chance of side effects such as dizziness, flushing or low blood pressure. If you are using Sildenafil, it is sensible to avoid drinking heavily before sex.

Avoid grapefruit or grapefruit juice unless your clinician says it is safe, as it may affect how some medicines are processed in the body.

Who can take Sildenafil?

Sildenafil may be suitable for many adult men aged 18 and over with erectile dysfunction. It is not suitable for everyone, which is why an online clinical assessment is needed before supply.

You must answer the consultation questions honestly, especially about your heart health, blood pressure, medicines and any previous side effects from ED treatment.

Who should not take Sildenafil?

Sildenafil may not be suitable if you:

• take nitrates for chest pain or angina, such as GTN spray or isosorbide mononitrate
• take riociguat for pulmonary hypertension
• have been advised to avoid sexual activity because of a heart condition
• have recently had a heart attack or stroke
• have very low blood pressure or uncontrolled high blood pressure
• have severe liver disease
• have certain inherited eye conditions such as retinitis pigmentosa
• have had sudden vision loss from a condition called NAION
• have a penis deformity or Peyronie’s disease
• have sickle cell disease, leukaemia or multiple myeloma
• have had an allergic reaction to Sildenafil or Viagra

Important: Sildenafil must not be taken with nitrates. Combining them can cause a dangerous fall in blood pressure.

Sildenafil side effects

Like all medicines, Sildenafil can cause side effects, although not everyone gets them. Common side effects are usually mild and short-lived.

Common side effects may include:

• headache
• flushing or hot flushes
• indigestion or heartburn
• blocked or stuffy nose
• feeling dizzy
• feeling sick
• temporary changes in vision

Speak to a doctor or pharmacist if side effects are troublesome, do not settle, or you are unsure whether Sildenafil is suitable for you.

When should I get urgent medical help?

Stop taking Sildenafil and seek urgent medical help if you experience:

• chest pain during or after sex
• a painful erection or an erection lasting more than 2 hours
• sudden loss or reduction of vision
• a seizure or fit
• signs of a serious allergic reaction, such as swelling of the lips, face, tongue or throat, wheezing, breathing difficulty, or a severe rash

Call 999 or go to A&E if symptoms are severe or you think it may be an emergency. If you develop chest pain after taking Sildenafil and you normally use nitrates, do not take nitrates until you have received urgent medical advice.

How can I reduce the risk of Sildenafil side effects?

• Use the strength approved by your prescriber.
• Do not take more than one tablet in 24 hours.
• Avoid heavy alcohol intake before sex.
• Avoid combining Sildenafil with other ED medicines.
• Tell the prescriber about all medicines you take, including blood pressure tablets and recreational drugs.
• Do not use Sildenafil if you take nitrates or poppers, as this can be dangerous.

Sildenafil interactions and precautions

Sildenafil can interact with some medicines and substances. You should tell the prescriber if you take:

• nitrates for chest pain or angina
• riociguat for pulmonary hypertension
• alpha-blockers
• blood pressure medicines
• HIV medicines or certain antifungals and antibiotics
• other erectile dysfunction medicines, including Tadalafil, Vardenafil or Avanafil
• recreational drugs, especially poppers

If you are unsure whether a medicine interacts with Sildenafil, ask a doctor or pharmacist before taking it.

Sildenafil vs Tadalafil: which is better?

Sildenafil and Tadalafil are both PDE5 inhibitors used for erectile dysfunction, but they suit different situations.

You can read more about Tadalafil here.

Kamagra vs Sildenafil: is Kamagra legal in the UK?

Kamagra is often advertised online as a cheaper alternative to Viagra or Sildenafil. However, Kamagra is not legally supplied as a licensed ED medicine in the UK.

You should avoid buying Kamagra, “oral jelly”, “blue pills” or herbal Viagra from unregulated websites. These products may be fake, unsafe, incorrectly labelled or contain unknown ingredients.

For safety, buy ED treatment only from a regulated UK pharmacy or online service that completes proper clinical checks.

Does Sildenafil make you last longer?

Sildenafil is used to help with erections. It is not designed to delay ejaculation and is not a treatment for premature ejaculation.

If your main concern is finishing too quickly, you may need a different treatment approach. You can read more about premature ejaculation treatment.

Can Sildenafil improve sexual confidence?

Erectile dysfunction can affect confidence, relationships and mental wellbeing. For some men, effective treatment can reduce performance anxiety and help restore confidence.

However, Sildenafil only treats the physical erection response. If stress, anxiety, depression, relationship problems, pornography use or lifestyle factors are contributing to ED, it is worth addressing those too. Medication can help the mechanics, but it cannot do the awkward conversation for you.

Can I buy Sildenafil online in the UK?

Yes, you can buy Sildenafil online in the UK from a regulated pharmacy service after a suitable clinical assessment. You should avoid websites that sell ED tablets without any medical questions or safety checks.

Before buying Sildenafil online, check that:

• the pharmacy is registered with the General Pharmaceutical Council, also known as the GPhC
• there is a proper medical questionnaire or consultation
• a qualified prescriber or pharmacist reviews suitability
• the website explains side effects, interactions and who should not use the medicine
• you receive genuine medicine with a patient information leaflet
