Viagra has been around since 1998 1 and has changed the way men with erectile dysfunction think about sex. Its effectiveness is well known; it's one of the most popular ED drugs on the market.
But every man at some point has searched, “How long does it take for Viagra to work?” We’re here to answer that question and other concerns you probably have.
We’ll dive into how long it takes for Viagra to kick in, how long Viagra lasts, and what you can do to make it last longer.
How Does Viagra Work?
When you’re aroused, your body kick-starts a chemical reaction. A compound called nitric oxide is released, enhancing blood flow to the penis, which leads to an erection. Eventually, the body introduces phosphodiesterase type 5 (PDE5), causing the reversal of this reaction and the loss of the erection. 1
Viagra, containing the active ingredient sildenafil, belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. As the name suggests, these drugs inhibit PDE5, preventing the loss of your erection. 1
It’s important to note that Viagra only starts working once you get an erection. It doesn’t help with the initial arousal. Instead, it enables you to maintain the erection for a satisfying duration. 1
How Long Does It Take for Viagra to Work?
One of the most common questions about Viagra is how quickly it starts to work. Generally, Viagra takes around 30 minutes to 1 hour to kick in after consumption. The exact time depends on your age, health, and metabolism. 1
So, if you're planning to have sex, take Viagra 30 minutes to 4 hours beforehand, and you should be ready to go.
