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.

Safety Profile: Viagra vs Sildenafil Comparison

Identical Safety Profiles

Viagra and generic sildenafil share an identical safety profile because they contain the same active ingredient - sildenafil citrate. Both work as PDE5 inhibitors, blocking the enzyme phosphodiesterase type 5 to increase blood flow to the penis during sexual arousal. The safety considerations, contraindications, and potential side effects remain consistent regardless of whether you choose the branded or generic version.

Common Side Effects

Both Viagra and sildenafil may cause similar mild to moderate side effects including headaches, facial flushing, nasal congestion, and indigestion. These typically occur in 10-15% of users and often diminish as your body adjusts to the medication. More serious side effects are rare but may include sudden vision changes or prolonged erections lasting over four hours, which require immediate medical attention.

Who Cannot Safely Use These Medications

Certain individuals should not take either Viagra or sildenafil due to potentially dangerous interactions or health conditions. Men taking nitrate medications for chest pain face serious risks from combining these with any sildenafil-based treatment. Those with severe cardiovascular disease, recent heart attack or stroke, severe liver impairment, or very low blood pressure should avoid these medications. A thorough medical assessment identifies these contraindications before prescribing.

Value Comparison: Cost vs Effectiveness

Generic sildenafil typically costs 70-80% less than branded Viagra whilst providing identical therapeutic effects. Both medications contain the same concentration of active ingredient per tablet, work within the same timeframe (30-60 minutes), and maintain effectiveness for 4-6 hours. The only differences lie in tablet appearance, packaging, and price - not safety or efficacy.

Proper Usage for Maximum Safety

Safe use of either medication requires following prescribed dosing guidelines. The typical starting dose is 50mg, taken 30-60 minutes before sexual activity, with a maximum of one dose per 24 hours. Taking the medication with large or fatty meals may delay onset of action. Alcohol should be limited as it can reduce effectiveness and increase the risk of side effects like dizziness or low blood pressure.

Medical Assessment Requirements

Both Viagra and sildenafil require prescription following consultation with a qualified healthcare professional. Our UK-licensed prescribers assess your medical history, current medications, and cardiovascular health to ensure safe prescribing. This assessment helps identify potential drug interactions, underlying health conditions that might affect safety, and determines the most appropriate starting dose.

Choosing Between Viagra and Sildenafil

Your choice between branded Viagra and generic sildenafil often comes down to personal preference and budget considerations rather than safety differences. Some men prefer the familiarity of the branded option, whilst others appreciate the significant cost savings of the generic alternative. At EverydayMeds, we present both options during checkout, allowing you to make an informed decision after consultation.

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.
