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.

Common Viagra Pill Problems & Solutions

Storage and Quality Issues

Proper storage of your Viagra pill is crucial for maintaining effectiveness. Store tablets below 30°C in a dry place, away from direct sunlight and moisture. Expired medications may lose potency and should be disposed of safely through your local pharmacy. If your Viagra pills appear discoloured, cracked, or damaged, do not use them and contact your pharmacy for a replacement.

Timing and Effectiveness Concerns

Many patients report reduced effectiveness when taking their Viagra pill with large or fatty meals, which can delay absorption. For optimal results, take your medication on an empty stomach or with a light meal. The standard 50mg dose works within 30-60 minutes for most men, but some may require dose adjustment to 25mg or 100mg based on individual response and tolerability.

Side Effects and When to Seek Help

Common side effects include headache, facial flushing, and nasal congestion. However, seek immediate medical attention if you experience chest pain, sudden vision loss, or an erection lasting more than four hours. The MHRA emphasises that patients should never exceed one Viagra pill per 24-hour period, regardless of perceived effectiveness.

Drug Interactions and Safety

Never take Viagra pills with nitrate medications such as GTN spray or isosorbide, as this combination can cause dangerous drops in blood pressure. Alpha-blockers for prostate problems may also interact, requiring careful monitoring. Always inform your prescriber about all medications you're taking, including over-the-counter drugs and supplements.

Choosing Between Viagra and Sildenafil

Both branded Viagra and generic sildenafil contain the same active ingredient and work identically. EverydayMeds offers both options, allowing patients to choose based on personal preference and budget considerations. Generic sildenafil provides the same clinical effectiveness at a lower cost, whilst some patients prefer the branded version for psychological reassurance.

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.
