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.

Step-by-Step Instructions for Taking Viagra Safely

When to Take Viagra

Viagra should be taken approximately 30-60 minutes before you plan to engage in sexual activity. The medication typically begins working within this timeframe, though individual response times may vary. Some men find it works within 30 minutes, whilst others may need the full hour. The effects can last up to 4-6 hours, providing a suitable window for sexual activity without requiring precise timing.

It's crucial to understand that Viagra only works when you're sexually aroused. The medication doesn't automatically cause an erection but enhances your natural response to sexual stimulation by increasing blood flow to the penis.

Proper Dosage Instructions

Your prescriber will determine the appropriate starting dose, typically 50mg for most men. Viagra tablets should be swallowed whole with a glass of water. Never crush, chew, or split the tablets, as this can affect how the medication is absorbed and may increase the risk of side effects.

The dosage may be adjusted based on your response and tolerability. Some men may need a lower dose of 25mg if they experience side effects, whilst others might benefit from increasing to 100mg if the 50mg dose proves insufficient. Only your prescriber can determine the right dose adjustment.

Food and Drink Considerations

Viagra can be taken with or without food, but your meal choice may affect how quickly it works. High-fat meals can delay the medication's absorption, potentially extending the time before you notice effects. For optimal results, consider taking Viagra on an empty stomach or after a light meal.

Moderate alcohol consumption is generally acceptable, but excessive drinking can reduce Viagra's effectiveness and increase the likelihood of side effects such as dizziness or low blood pressure. Both alcohol and Viagra can lower blood pressure, so combining them requires caution.

Critical Safety Guidelines

Never take more than one Viagra tablet in a 24-hour period, regardless of the strength prescribed. Taking multiple doses doesn't improve effectiveness but significantly increases the risk of dangerous side effects, including potentially life-threatening drops in blood pressure.

If you're taking any nitrate medications for chest pain (such as GTN spray or isosorbide tablets), you must not take Viagra. This combination can cause a dangerous drop in blood pressure. Similarly, avoid recreational drugs containing nitrates, often called "poppers."

What to Expect When Taking Viagra

Common side effects include headache, facial flushing, indigestion, and nasal congestion. These effects are typically mild and temporary, often diminishing as your body adjusts to the medication. Visual disturbances, such as a blue tinge to vision or increased light sensitivity, may occur but usually resolve within a few hours.

If you experience an erection lasting more than 4 hours (priapism), seek immediate medical attention. This is a medical emergency that requires prompt treatment to prevent permanent damage.

Choosing Between Branded Viagra and Generic Sildenafil

EverydayMeds offers both branded Viagra and generic sildenafil at checkout, allowing you to choose based on your preferences and budget. Both contain the same active ingredient (sildenafil citrate) and work identically. The generic version provides the same effectiveness and safety profile at a lower cost, whilst some men prefer the branded product for peace of mind.

Storage and Handling

Store your Viagra tablets in their original packaging at room temperature, away from moisture and direct sunlight. Keep them out of reach of children and never share your medication with others. Each prescription is specifically assessed for your individual health profile and may not be safe for others.

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.
