Understanding the Mechanism of Action of PDE5 Inhibitors

But responsibility for the “in mind” part of the process is on you.

The little blue pill isn’t designed to increase libido or sex drive, clarifies Dr.

Non-medical use

Let’s set the record straight with the help of urologist Drogo Montague, MD. Odds are you’ve seen a Viagra commercial and heard this warning: Seek immediate medical help for an erection lasting four or more hours. It’s an attention-grabbing piece of cautionary advice. But the situation that it addresses — a condition known as priapism — is a relatively uncommon side effect of the medication, says Dr. Montague.

How can I get Viagra to work?

A study published in 2020 categorized long-lasting erections from Viagra and other ED medications as a “rare event.” Researchers found 411 cases of drug-induced priapism while reviewing more than two decades worth of data. But your odds of problematic prolonged erections increase if you combine Viagra with certain penile injection therapies, notes Dr. Montague. “Combining the treatments has a cumulative effect — penile injection therapy makes your erections hard, and adding Viagra makes them harder and even more long-lasting,” he continues. “So stay on the safe side and don’t pair them.” Here’s a fun fact for you: Viagra was created to help your heart.

Does sildenafil interact with other medicines (drug interactions)?

Researchers initially developed Viagra to treat angina, a type of chest pain. Angina occurs when your heart doesn’t get enough oxygen-rich blood and starts working harder to compensate. Now, Viagra didn’t exactly shine as a treatment for angina … but the stiffer erections the little blue pill caused certainly stood out as a side benefit. Which brings us back to the question regarding Viagra and your heart. The erectile dysfunction medication isn’t harmful to your ticker when taken on its own. Montague. Basically, think of Viagra as a performance enhancer as opposed to a mood setter. ED is more common with age, but that doesn’t mean it’s not an issue for the younger crowd. Studies show that nearly 40% of men are affected by ED by age 40.

It can happen much, much earlier, too. Talking to your healthcare provider about ED and ED medications also may help you save your penis from injury. Having sex with an erection vardenafil tablets that’s barely “hard enough” can bend your penis and tear tissue that may scar while healing. As scar tissue isn’t elastic like healthy penile tissue, it can force your penis to bend with future erections. That can lead to a condition known as Peyronie’s disease. Taking Viagra or another ED medication can bring a firmness that prevents the issue. “If you’re having erectile dysfunction problems, you should feel confident going to your doctor no matter your age,” reassures Dr. Montague.

“Many men are embarrassed, but they shouldn’t be. Help is available, and it’s worth a try.” Viagra is approved for use to treat ED after age 18.

What other information should I know?

That’s an important caveat because Viagra should NOT be taken with heart medications that include nitrates. Like nitrates, Viagra helps dilate (or expand) blood vessels constricted by coronary artery disease. Your blood pressure drops when this happens, as less force is needed to pump blood through your system. The worry if you take both Viagra and nitrates is that your blood pressure could drop too low, a condition known as hypotension. Abnormally low blood pressure increases your risk of a heart attack or stroke.
