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.

Understanding Sildenafil: Benefits and Considerations

The Advantages of Sildenafil Citrate

Sildenafil citrate offers several compelling benefits for men experiencing erectile dysfunction. The most significant advantage is cost-effectiveness - as the generic version of Viagra, sildenafil provides the same active ingredient and therapeutic effect at a fraction of the price of the branded alternative. This makes long-term treatment more financially accessible for many patients.

Clinical effectiveness remains sildenafil's strongest selling point. The medication works by inhibiting the PDE5 enzyme, increasing blood flow to the penis when sexually aroused. Studies consistently show that sildenafil helps approximately 70-80% of men achieve and maintain erections suitable for sexual activity. The medication typically works within 30-60 minutes and effects can last 4-6 hours, providing a reliable window for intimacy.

Flexibility in dosing represents another advantage. Available in 25mg, 50mg, and 100mg strengths, treatment can be tailored to individual needs and tolerability. Most men start with 50mg, with doses adjusted based on effectiveness and any side effects experienced. At EverydayMeds, patients can choose between generic sildenafil and branded Viagra at checkout, allowing personal preference to guide their decision.

Potential Drawbacks and Side Effects

Despite its benefits, sildenafil citrate does have limitations and potential side effects that require consideration. Common side effects include headaches (affecting up to 16% of users), flushing, nasal congestion, and stomach upset. These effects are generally mild and temporary but can be bothersome for some men.

More concerning are the cardiovascular considerations. Sildenafil can cause a temporary drop in blood pressure, which may be problematic for men with existing heart conditions or those taking certain medications. The medication is absolutely contraindicated with nitrate medications (used for chest pain), as this combination can cause a dangerous drop in blood pressure.

Timing requirements can also present challenges. Sildenafil must be taken 30-60 minutes before sexual activity, requiring some planning. Fatty meals can delay the medication's onset, potentially extending this window further. Some men find this advance planning reduces spontaneity in their relationships.

Who Should Avoid Sildenafil

Sildenafil isn't suitable for everyone. Men taking nitrate medications, those with severe heart disease, recent stroke or heart attack (within six months), or severe liver problems should not use sildenafil. The medication also interacts with certain other drugs, including some blood pressure medications and antifungal treatments.

Age alone doesn't disqualify men from using sildenafil, but older patients may be more sensitive to side effects and drug interactions. A thorough medical assessment is essential to ensure safe prescribing.

Making the Right Choice

When weighing sildenafil's pros and cons, consider your individual circumstances, medical history, and treatment goals. The medication's proven effectiveness and affordability make it an attractive option for many men, but potential side effects and interactions require careful evaluation. At EverydayMeds, our clinical team conducts thorough assessments to ensure sildenafil is appropriate for each patient's unique situation, with both generic and branded options available based on personal preference.

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.
