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 Side Effects and Management Strategies

Most Frequent Side Effects

The most commonly reported side effects with Viagra include headaches, facial flushing, indigestion, and nasal congestion. These effects occur because sildenafil affects blood vessels throughout the body, not just in the penis. Most men experience mild symptoms that fade within 2-4 hours as the medication is processed by the body.

Managing Headaches

Headaches affect approximately 16% of Viagra users and are usually mild to moderate. Stay well-hydrated by drinking plenty of water before and after taking the medication. Over-the-counter paracetamol can be safely used alongside Viagra if needed. Avoid ibuprofen or aspirin as these may increase the risk of bleeding when combined with sildenafil.

Dealing with Facial Flushing

Facial flushing or redness occurs in about 10% of users due to increased blood flow. This typically resolves naturally within 1-2 hours. Cool compresses applied to the face may provide relief. Avoiding alcohol, spicy foods, and hot environments can help reduce the intensity of flushing.

Digestive Side Effects

Indigestion, nausea, or stomach upset affects around 7% of users. Taking Viagra on an empty stomach reduces these effects. If you must eat beforehand, choose light, non-fatty foods. Fatty meals can delay absorption and worsen digestive symptoms while reducing effectiveness.

Visual Disturbances

Some men experience mild visual changes such as increased light sensitivity or a blue tinge to vision. These effects are temporary and harmless in most cases. However, if you experience sudden vision loss or prolonged visual disturbances, seek immediate medical attention as this may indicate a rare but serious side effect.

When to Seek Medical Help

While most side effects are manageable, certain symptoms require urgent medical attention. Seek immediate help if you experience chest pain, irregular heartbeat, sudden severe headache, or an erection lasting more than 4 hours. These rare but serious side effects need prompt medical intervention.

Choosing Between Viagra and Generic Sildenafil

Both branded Viagra and generic sildenafil contain the same active ingredient and have identical side effect profiles. Some patients prefer branded Viagra for peace of mind, while others choose generic sildenafil for cost savings. EverydayMeds offers both options, allowing you to select the most suitable choice for your needs and budget during checkout.

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.
