Specialists in medicine, nutrition, performance, and sexual health. BSc (Hons) MBBS MRCGP AFHEA MA (Hons) AFMCP I felt fairly comfortable talking to my partner about my ED. I was actually more nervous speaking to the doctor about it, but when I found Numan, I realised it was very easy to get it sorted discreetly. I think any sort of relationship where you can’t fulfil someone’s needs is a bit of a deal breaker. It’s given me confidence as I know it’s going to work.

Answer a few simple questions to get the treatment you need. Erectile dysfunction affects approximately half of all men between 40 and 70 years old in the UK. If you’re searching for the best erectile dysfunction treatment UK options, you’re certainly not alone, and the good news is that effective treatments are widely available.
Can you change your sildenafil dosage yourself?
So if it looks like too much of a good deal, it most likely is. Sildenafil was first brought to the UK market by global pharmaceutical giants, Pfizer, and it was only available under their brand name, Viagra. This exclusivity meant the price tag was high and many men couldn’t afford this type of legitimate ED medication. In 2013, however, Pfizer’s patent expired, and it became legal to manufacture the drug under its generic name, Sildenafil. Here at Manual, we provide a digital consulting service.
How does Vardenafil work?
The recommended retail price for branded Viagra Connect is equivalent to about £5 per pill. At Manual, the same Sildenafil is available for as little as £2 per tablet. Firstly, it’s important to know that side effects are rare. However, when they do occur, the most common side effects of Sildenafil are: headaches, facial flushing, indigestion, nasal congestion, dizziness, nausea, hot flushes, vision changes (such as having a blue colour tinge, or blurred vision). Serious side effects can become more common when Sildenafil is misused, mixed with excessive alcohol, or due to drug interactions with other medications. Finding the right solution can feel overwhelming. With various medications, therapies, and approaches on offer, knowing where to start isn’t always straightforward. As a consultant urological surgeon, Mr Ashwin Sridhar regularly helps men navigate these options, providing expert guidance on treatments that suit their individual circumstances and underlying health conditions. This guide compares six proven erectile dysfunction treatments available in the UK. You’ll learn how each option works, their key differences, and what to consider when choosing between them, whether you’re exploring NHS pathways or private specialist care. A private urology consultation provides the most thorough assessment of erectile dysfunction and often reveals underlying health conditions that simpler solutions might miss.
Should I tell my partner I’m taking ED pills?
In people with ED, an enzyme called PDE5 ed gels breaks down cGMP too quickly, reducing blood flow and causing the erection to fade. ED treatments block PDE5, helping more blood reach the penis. This leads to firmer, longer-lasting erections. Treat the symptoms with ED medication, and get 50% off an ED blood test to investigate the underlying cause.2-5 1 in 3 men with ED have low-T If left untreated, leads to higher risk of stroke and heart attacks 62% of people with heart disease have ED If left untreated, vascular problems can be fatal 65% of men with diabetes have ED Around 80-85% of people with type 2 diabetes are overweight or obese Untreated diabetes can lead to blindness, kidney failure and heart attacks Reclaim your confidence in the bedroom with clinically proven ED treatments delivered to your door.

Should I Get Surgery for Erectile Dysfunction?
When and how should I start treatment? Here at Manual, all of our medication comes from the officially accredited Manual Pharmacy. Before you buy, you will receive a consultation from one of our clinicians, who are all registered with the UK’s General Pharmaceutical Council. Our pharmacist will prescribe you the correct dose of Sildenafil to best treat your ED. The normal dosage of Sildenafil is 50mg, and this has the desired effect for the vast majority of men who use it.

It can also be taken in 25mg and 100mg forms. When you take Sildenafil for the first time, the most important thing is to relax and enjoy some sexual stimulation. This will give the drug the best chance to kick in and help you get the firm erection you’re looking for. Learn more about first-time use of Sildenafil on our blog. Sildenafil is the world’s most counterfeited drug – and there are many online vendors trying to pull a fast one. Your urologist will start by taking a detailed medical history, including questions about when your symptoms began, how they affect your relationships, and any other health conditions you have. They’ll perform a physical examination to assess your cardiovascular health, check for signs of hormonal imbalances, and evaluate nerve function in the genital area. This initial assessment helps identify whether your erectile dysfunction stems from physical causes, psychological factors, or a combination of both.

Cardiovascular disease, diabetes, and high blood pressure frequently contribute to erectile dysfunction, and your urologist will assess how well these conditions are controlled. They’ll also examine lifestyle factors such as smoking, alcohol consumption, and stress levels, as these often play a significant role in sexual function. Erectile dysfunction can be an early warning sign of heart disease, sometimes appearing up to three years before cardiovascular symptoms develop. Hormonal imbalances, particularly low testosterone, may also affect your ability to achieve and maintain erections.
