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 How Viagra Works Safely

What Makes Viagra Safe When Used Properly?

Viagra contains sildenafil citrate, a PDE5 inhibitor that has undergone extensive clinical testing. When you're sexually aroused, Viagra helps increase blood flow to the penis by relaxing blood vessels. It's important to understand that Viagra doesn't cause automatic erections - sexual stimulation is still required. The medication has been prescribed safely to millions of men worldwide when used under proper medical supervision.

Starting Your First Dose Safely

Most men begin with a 50mg dose, taken approximately one hour before sexual activity. This starting dose allows your body to adjust to the medication while minimising potential side effects. Your healthcare provider may adjust this to 25mg if you experience side effects, or increase to 100mg if the initial dose isn't effective. Never take more than one dose in a 24-hour period, regardless of the strength.

Essential Safety Checks Before Taking Viagra

Before starting Viagra, a thorough medical assessment ensures the treatment is safe for you. This includes reviewing your cardiovascular health, current medications, and medical history. Men taking nitrate medications (such as GTN spray) cannot safely use Viagra due to dangerous interactions that can cause severe drops in blood pressure. Similarly, those with serious heart conditions, recent strokes, or severe liver problems may need alternative treatments.

What to Expect During Your First Experience

Viagra typically begins working within 30-60 minutes of taking it. The effects can last up to 4-6 hours, though this doesn't mean you'll have an erection for this entire time. Some men notice the medication works faster on an empty stomach, as fatty meals can delay absorption. Mild side effects like headaches, flushing, or nasal congestion are common and usually temporary as your body adjusts.

Choosing Between Viagra and Generic Sildenafil

At EverydayMeds, patients can choose between branded Viagra and generic sildenafil at checkout. Both contain identical active ingredients and work in exactly the same way. The main difference is cost - generic sildenafil offers the same therapeutic benefits at a lower price point. Your choice between branded or generic depends entirely on personal preference, as both options maintain the same safety profile and effectiveness.

Monitoring Your Response and Safety

During your first few uses, pay attention to how your body responds. Most side effects are mild and decrease over time. However, seek immediate medical attention if you experience chest pain, sudden vision changes, or an erection lasting longer than four hours. Keep track of the medication's effectiveness and any side effects to discuss with your healthcare provider during follow-up consultations.

Long-term Safety Considerations

Regular check-ups ensure Viagra remains safe and appropriate for your changing health needs. Your doctor may adjust your dose based on your response and any new health conditions or medications. Maintaining open communication with your healthcare provider helps optimise both safety and effectiveness throughout your treatment journey.

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.
