What Is Sildenafil and How Does It Differ from Viagra?

Sildenafil is the active ingredient found in branded Viagra, manufactured by Pfizer. Since the Viagra patent expired in 2013, generic sildenafil has been legally available in the UK at a significantly lower cost, making it the most popular erectile dysfunction treatment online. Both branded and generic versions contain the same active ingredient and are regulated to the same standard by the Medicines and Healthcare products Regulatory Agency (MHRA). Generic Viagra UK options are available in 25mg, 50mg, and 100mg strengths.

Sildenafil 50mg Tablets

The 50mg dose is the most commonly prescribed starting strength. It offers a balance between effectiveness and tolerability for most men with erectile dysfunction. Many clinicians recommend starting at 50mg before adjusting the dose based on response and any side effects experienced.

Sildenafil 100mg Tablets

The 100mg strength is the maximum recommended dose and is generally prescribed when 50mg has not produced a satisfactory response. It should only be taken on the advice of a prescriber and is not suitable for everyone, particularly those taking certain other medications.

What Causes Erectile Dysfunction?

Erectile dysfunction is more common than many men realise, affecting around one in five men in the UK at some point in their lives. It can be caused by both physical and psychological factors, and in many cases a combination of both. Understanding the underlying cause can help guide the most appropriate treatment.

  • Reduced blood flow to the penis caused by cardiovascular disease or high blood pressure
  • Type 2 diabetes affecting nerve and blood vessel function
  • Hormonal imbalances, including low testosterone levels
  • Psychological factors such as anxiety, depression, or stress
  • Lifestyle factors including smoking, excessive alcohol consumption, and obesity
  • Side effects from certain prescription medications

How Does Sildenafil Work?

Sildenafil belongs to a class of medicines called PDE5 inhibitors. During sexual arousal, the body releases nitric oxide, which triggers a chemical process increasing blood flow to the erectile tissue of the penis. Sildenafil works by blocking the PDE5 enzyme, which would otherwise restrict this process. This allows blood vessels to relax and blood flow to increase, supporting a natural erection in response to sexual stimulation. It does not cause an erection on its own — arousal is still required.

When and How to Take Sildenafil

Sildenafil tablets should be taken approximately 30 to 60 minutes before sexual activity. The effects can last for up to four to six hours. It is best taken on an empty stomach or after a light meal, as high-fat foods can delay absorption. You should not take more than one dose in any 24-hour period.

Are There Any Side Effects?

Like all medicines, sildenafil can cause side effects, though not everyone experiences them. Common side effects include headaches, facial flushing, indigestion, and nasal congestion. Less commonly, some men may notice visual disturbances or dizziness. If you experience chest pain, sudden vision loss, or a prolonged erection lasting more than four hours, seek urgent medical attention. Always consult a pharmacist or GP if you have concerns about side effects or interactions with other medicines.

Who Can Use Sildenafil Tablets?

Sildenafil is suitable for adult men aged 18 and over who have been diagnosed with erectile dysfunction. It is not appropriate for everyone, and a medical consultation is required before it can be dispensed. The following groups should seek specific medical advice:

  1. Men taking nitrate-based medicines for heart conditions — sildenafil can cause a dangerous drop in blood pressure when combined with nitrates
  2. Men who have recently had a stroke, heart attack, or serious cardiovascular event
  3. Men with severe liver or kidney impairment
  4. Men with a history of non-arteritic anterior ischaemic optic neuropathy (NAION)
  5. Those with rare inherited eye conditions such as retinitis pigmentosa

Sildenafil is not intended for use by women or anyone under 18. If you are unsure whether this treatment is appropriate for you, speak to your GP or a qualified pharmacist before purchasing.

What is the difference between cheap sildenafil and branded Viagra?

Sildenafil is the generic version of Viagra and contains exactly the same active ingredient. Both are regulated to the same safety standard in the UK. The key difference is cost — generic sildenafil is considerably cheaper because manufacturers do not carry the original research and development expenses.

Can I buy sildenafil online without a prescription in the UK?

Sildenafil 50mg can be supplied by a pharmacist without a traditional GP prescription in the UK, but you must complete a clinical consultation first. This ensures the medication is safe for you. Higher doses such as 100mg always require a prescription from a qualified prescriber.

How quickly does sildenafil work?

Sildenafil typically starts working within 30 to 60 minutes of taking a tablet. It works best when taken on an empty stomach or after a light meal. The effects can last up to four to six hours, though this varies between individuals.

Is it safe to buy cheap sildenafil online UK?

It is safe provided you purchase from a GPhC-registered online pharmacy that requires a proper medical consultation before dispensing. Avoid unregulated websites, as counterfeit erectile dysfunction treatments are widely reported. Always check for the GPhC registered pharmacy logo before making a purchase.

What dose of sildenafil should I start with?

Most men are advised to start with the 50mg dose. Your prescriber may recommend increasing to 100mg if 50mg is not effective, or reducing to 25mg if side effects are a concern. Never take more than one dose in 24 hours. Speak to a pharmacist or GP if you are unsure.

Can I take sildenafil with alcohol?

You should avoid drinking excessive amounts of alcohol when taking sildenafil. Alcohol can increase the risk of side effects such as dizziness and may also make it harder to achieve an erection. Moderate alcohol consumption is generally considered acceptable, but it is best to be cautious.

How long does delivery take when I buy sildenafil tablets UK online?

Delivery times vary by pharmacy, but many registered UK online pharmacies offer next-day or two-day tracked delivery with discreet packaging. At Cured Pharmacy, we aim to dispatch approved prescriptions promptly so you receive your sildenafil tablets quickly and confidentially.

Are there any alternatives to sildenafil for erectile dysfunction?

Yes. Other PDE5 inhibitors available in the UK include tadalafil (Cialis), vardenafil (Levitra), and avanafil (Spedra). Each works in a similar way but differs in onset time and duration. Tadalafil, for example, can last up to 36 hours. A pharmacist or GP can help you choose the most suitable Viagra alternative online UK.
