Viagra vs Levitra vs Cialis
Erectile dysfunction (ED) is a common condition that affects millions of men in the UK. Fortunately, several effective treatments are available, with Viagra (Sildenafil), Cialis (Tadalafil), and Levitra (Vardenafil) being the most popular options. But which one is best for you? This guide will compare these medications, including their effectiveness, duration, side effects, and costs, helping you make an informed choice.
Key Takeaways
Viagra, Cialis, and Levitra all help with erections, but work differently.
Viagra lasts up to 4 hours, Cialis can last up to 36 hours, and Levitra is similar to Viagra but may have fewer side effects.
Viagra is the cheapest, Cialis is best for spontaneity, and Levitra may have fewer side effects.
If you want the most affordable option, Viagra (Sildenafil) is a great choice. Cialis lasts the longest, and Levitra is gentler on the stomach.
You need to choose based on your needs.
If you want a long-lasting effect, Cialis is best. If you prefer a budget-friendly option, go for Viagra. If you have stomach issues, Levitra might be a better choice. Always speak to your doctor before starting any medication to ensure it is safe and suitable for you.
How Do Viagra, Levitra, and Cialis Work?
Viagra, Cialis, and Levitra all belong to a group of drugs called PDE5 inhibitors. These medications work by blocking the enzyme phosphodiesterase type 5 (PDE5), which helps increase nitric oxide levels in the body. This leads to the relaxation of blood vessels, allowing more blood to flow to the penis, making it easier to achieve and maintain an erection when sexually stimulated.
