Overview

Viagra is the world’s most recognised treatment for erectile dysfunction (ED), trusted by millions of men for over two decades. Its distinctive blue tablet has become a symbol of reliability, helping men restore confidence, intimacy, and control in their sex lives.

Viagra contains sildenafil citrate, a proven PDE5 inhibitor that works by improving blood flow to the penis. Taken around an hour before sexual activity, it helps achieve firmer, longer-lasting erections when aroused — giving men the reassurance of knowing their body will respond when it matters most.

What makes Viagra stand out is not just its effectiveness, but also its track record of safety. Backed by years of clinical research and real-world use, it remains the go-to choice for many men seeking a trusted ED treatment.

At SwiftMedi, your health and privacy always come first. Every order of Viagra is reviewed by a UK-registered prescriber to confirm it’s suitable for you. Treatment is then delivered quickly and discreetly — so you can focus on feeling your best again, without any unnecessary worry or embarrassment.

 

What is Viagra?


Viagra is a widely recognised brand name for the medication sildenafil, used to treat erectile dysfunction (ED). It helps men who find it difficult to achieve or maintain an erection firm enough for sexual intercourse. While erectile dysfunction is common—affecting over half of men aged 40 to 70—Viagra provides an effective and reliable solution to restore sexual function and improve quality of life.

Viagra is the original sildenafil medication and remains a popular choice for men seeking fast, effective treatment. At SwiftMedi, we also offer generic sildenafil tablets, which contain the same active ingredient as Viagra and provide an equally effective but more affordable alternative. Both options are prescribed after a medical assessment to ensure safety and suitability.

 

Directions

How to Take Viagra


Viagra tablets should be taken orally about 30 to 60 minutes before sexual activity. The medication can be taken with or without water and is most effective on an empty stomach. Its effects typically last up to four hours, providing a flexible time frame for intimacy.

Tips for use:

  • Avoid heavy or fatty meals before taking Viagra to ensure quick onset
  • Swallow tablets whole with water
  • Do not take more than one dose in 24 hours

 

Dosage Options


Viagra is available in 25mg, 50mg, and 100mg doses. Most men begin treatment with 50mg, adjusting up or down depending on how well the medication works and any side effects experienced. Your doctor or pharmacist will advise the appropriate dosage based on your health profile.

Possible Side Effects
