Buy Viagra Tablets (25mg, 50mg, 100mg) Online in the UK 

Viagra is the most well-known treatment for erectile dysfunction (ED), which is commonly known as the little blue pill. It is made with sildenafil citrate and helps men obtain firmer, harder erections during sexual activity. 

Viagra increases the flow of blood to your penis when you’re aroused. It’s not going to bring about an erection on its own — you still need to be aroused for it to work properly.
 

Available Strengths and Pack Sizes 

Viagra tablets are available in 25, 50, and 100mg doses, which can be ordered online in packs of 4, 8, 16, 32, or 64 tablets. Offering you flexibility. 

How Viagra Works 

The body releases nitric oxide during arousal, relaxing blood vessels and boosting blood flow to the penis — creating an erection. 

This becomes difficult for men with ED to keep up with this process. Viagra (sildenafil citrate)  works by blocking the PDE5 enzyme, which allows nitric oxide to perform effectively, leading to stronger and longer-lasting erections during arousal. 

Key Features 

  • Oral, “on-demand” treatment for erectile dysfunction 
  • Starts working within 30 minutes to 1 hour 
  • Lasts up to 4 hours 
  • Available in multiple strengths: 25mg, 50mg, 100mg 
  • Only works when sexually aroused — no spontaneous erections 
  • Trusted, original brand medication from the makers of sildenafil

How to Use Viagra Tablets (25mg, 50mg, 100mg) 

Viagra film-coated tablets are a prescription treatment only, so before you can be considered for treatment, your pharmacist must determine which dose is suitable for you. 

Before using this product, read the Patient Information Leaflet that comes with your medicine for full instructions and safety information. 

Viagra is simple to use, but timing and dosage matter for the best results. 

  • Take one tablet about 30 minutes to 1 hour before sex. 
  • Swallow the tablet whole with a full glass of water. 
  • Avoid heavy or high-fat meals before taking it, as this can delay the effect. 
  • The effects can last for up to 4 hours, but you should only take one dose in 24 hours. 
  • Do not mix with alcohol or recreational drugs like poppers, as this can reduce effectiveness or cause side effects. 

Dosage 

The typical starting dose for most men is 50mg, taken as needed — ideally 30 minutes to one hour before sexual activity. Your pharmacist may recommend a dose change based on how your body responds. For some men, 25mg is a sufficient dose and reduces the intensity of side effects; others may require a higher dosage, 100mg, or simply do not respond well to the lower dose. You must NOT take more than 1 tablet in a 24-hour period. Taking more than the recommended amount will not improve your performance and may increase the likelihood of side effects. 

How Long Does Viagra Take to Work? 

Normally, it kicks in by the half-hour to hour mark, depending on your metabolism and what you’ve eaten. Once it’s active, the effects can last for up to 4 hours, allowing you to have and achieve a strong, lasting erection. But remember, Viagra won’t give you an instant erection — it still needs to be taken in conjunction with sexual stimulation for the best results. 

If you find that the effects are too strong or too weak, or if you experience any side effects, you should speak to your pharmacist. They can help adjust your dose to the right amount. 

Side Effects of Viagra Tablets (25mg, 50mg, 100mg)

If any of these occur, stop taking Viagra and seek medical help immediately.
