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.

What to Expect When Taking Viagra for the First Time

Understanding How Viagra Works

Viagra contains sildenafil citrate, a PDE5 inhibitor that increases blood flow to the penis during sexual arousal. It's important to understand that Viagra doesn't cause spontaneous erections - sexual stimulation is still required. The medication works by blocking the phosphodiesterase type 5 enzyme, which helps maintain improved blood circulation when you're sexually aroused.

Choosing Your First Dose

Most men start with a 50mg dose of Viagra, which is considered the standard starting point. Your prescriber may recommend a lower 25mg dose if you have certain health conditions or take specific medications. The 100mg dose is typically reserved for those who don't respond adequately to 50mg. EverydayMeds offers both branded Viagra and generic Sildenafil in all three strengths, allowing you to choose based on your preference and budget.

Timing and Food Considerations

Take Viagra approximately 30-60 minutes before you plan to be sexually active. The medication works more effectively on an empty stomach, as fatty foods can delay absorption and reduce effectiveness. If you've eaten a heavy meal, consider waiting 2-3 hours before taking your dose, or plan to take it earlier than usual.

What to Expect During Your First Experience

Many first-time users wonder what they'll feel when Viagra starts working. Most men don't notice obvious physical sensations when the medication becomes active. Instead, you may find it easier to achieve and maintain an erection when sexually aroused. Some men experience mild side effects like facial flushing, headache, or nasal congestion - these are generally mild and temporary.

Common First-Time Concerns

Performance anxiety can actually interfere with Viagra's effectiveness, so try to remain relaxed and remember that the medication typically works well for most men. Don't panic if it doesn't work perfectly the first time - stress, alcohol, fatigue, or other factors can influence effectiveness. Some men find the medication works better on the second or third attempt once anxiety decreases.

Safety Considerations for New Users

Never exceed one dose within 24 hours, regardless of effectiveness. If you take medications containing nitrates or have serious heart conditions, Viagra may not be suitable for you. Always complete an honest clinical assessment with a qualified prescriber before starting treatment. This ensures the medication is safe and appropriate for your individual circumstances.

When to Seek Advice

Contact a healthcare provider if you experience an erection lasting more than 4 hours, severe side effects, or chest pain during sexual activity. Most side effects are mild, but it's important to know when to seek help. EverydayMeds provides ongoing support and guidance 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.
