How ED treatment works in your body.

Increases blood flow

Increases blood flow

When PDE5 is suppressed, blood is able to flow more freely through the body—including to the (you guessed it) penis.

Increase erections

Increase erections

More blood flow to the penis means harder, more satisfying erections once you're sexually stimulated.

Why Sildenafil May Stop Working Over Time

Common Reasons for Reduced Effectiveness

When sildenafil or Viagra stops working as effectively, several factors may be responsible. Lifestyle changes often play a significant role - increased stress levels, poor sleep patterns, excessive alcohol consumption, or weight gain can all impact how well the medication works. Additionally, as men age, underlying cardiovascular health may decline, affecting blood flow and reducing the medication's effectiveness.

Medication and Health Factors

New medications can interfere with sildenafil's effectiveness. Antidepressants, blood pressure medications, or antihistamines may reduce its efficacy. Developing health conditions such as diabetes, high blood pressure, or cardiovascular disease can also impact treatment success. It's important to review any changes in your health or medications with a healthcare provider when experiencing reduced effectiveness.

Dosage and Timing Considerations

Sometimes the issue isn't that the medication has stopped working entirely, but that your needs have changed. Your prescribed dosage may need adjustment - sildenafil is available in 25mg, 50mg, and 100mg strengths. Timing can also be crucial; taking the medication with large or fatty meals can significantly delay its onset of action. The medication should typically be taken 30-60 minutes before sexual activity on a relatively empty stomach for optimal results.

Psychological Factors

Performance anxiety can create a cycle where concerns about the medication not working actually contribute to its reduced effectiveness. Stress, relationship issues, or depression can all impact sexual function regardless of medication. Addressing these underlying psychological factors is often essential for restoring treatment effectiveness.

Solutions and Next Steps

If you're experiencing reduced effectiveness with sildenafil, several options may help. Your healthcare provider might recommend adjusting your dosage, switching between branded Viagra and generic sildenafil (some patients respond differently to different formulations), or exploring timing adjustments. Lifestyle modifications such as reducing alcohol intake, improving sleep, managing stress, and increasing physical activity can significantly improve results. At EverydayMeds, we offer both Viagra and sildenafil options, allowing you to work with our prescribers to find the most suitable treatment approach. In some cases, switching to alternative ED treatments or combining approaches may be recommended.

What you need to know about erectile dysfunction

It's one of the most common conditions we treat, and one of the most treatable.

What is Erectile Dysfunction?
ED means finding it hard to get or keep an erection firm enough for sex. It's not unusual to have an off night; the point at which it's worth doing something is when it's happening regularly, or when it's starting to bother you.
How will I feel when I take ED medication?
For most men, nothing feels different day to day. The medication works in the background — when you're sexually aroused, it helps blood flow where it's needed, so erections come more easily and last longer. It doesn't cause arousal on its own. Some men notice mild, short-lived effects like a headache, facial flushing or a stuffy nose, which usually pass as the dose wears off.
Why do I need a prescription for ED medication?
ED treatments are prescription-only medicines in the UK because they aren't suitable for everyone — for example, alongside certain heart conditions or medications like nitrates. That's why we ask you to complete a short online consultation first. A UK-registered prescriber reviews your answers to make sure your chosen treatment is safe and right for you before it's dispensed.
