But it does frequently cause nasal congestion, unrelated to sexual simulation

It’s not unrelated actually, there is some tissue inside the nose cavity that is similar to the erectile tissue of the penis. That’s why the nose gets “stuffy” from sildenafil, and that’s why you sometimes sneeze when aroused.

See also levomethamphetamine, the mirror image of meth found commonly in drugstores in Vick’s inhalers, acting as a vasoconstrictor

> nothing except facial flushing What does this mean?

Person takes pill, face gets a bit more rosy than usual. I guess it has an effect on small blood vessels everywhere.

Thank you.

Well. too sad I can't take it. It gives me terrible heartburn (an acute stomach pain, not a heart related condition) that only partially responds to anti-acids such as Alka Seltzer. Also, extremelly stuffy nose, to the point where basically I need to breath by the mouth. And the red eyes, eyes as red as if had just smoke the biggest and strongest joint ever. Yes, I tried to use it recreationally a few times. It is no…

> Also, extremelly stuffy nose, to the point where basically I need to breath by the mouth. And the red eyes, eyes as red as if had just smoke the biggest and strongest joint ever. Looks like an allergic reaction; it could be not so much in sildenafil itself, but what they use as filler for the pills.

Stuffy nose is a common side effect of sildenafil itself. UK NHS lists common side effects as anything affecting more than 1 in 100 patients.

50mg 3x a day, according to the study: https://www.ahajournals.org/doi/10.1161/CIRCRESAHA.124.32432... Seems high to me, but I've never taken the drug. I assume most people take it just a few times a week for it's intended use? Is anyone aware of research that shows positive benefits to health at recreational doses?

That’s a standard dose. 3X per day is because it has a short half life. > Is anyone aware of research that shows positive benefits to health at recreational doses? Recreational doses? What does that mean? Excessive vasodilation isn’t going to be fun. You actually need some vasoconstriction to balance your blood pressure. Too much and you’re just going to get headaches and lightheaded. Excessive vasodilation would be…

So Extended Release Sindafil is about to hit the market hard?

Reminds of me how ER Guanfacine was brought to market as and ADHD drugs.

Why invent new drugs when you can put new wrappers on old ones?

Or they grew accustomed to the erections and no longer found them annoying, which is how I read it.

There must be a market for pants that have room for this.

Sadly I remember wearing pleated pants

Hmm I thought viagra improves blood flow in opposite place but 2 for price of 1 is great too

I think it just causes vasodilation anywhere in the body?

This makes me wonder -- why do things like stimulants, caffeine, and cold medicine help people think clearly?

Aren't they vasoconstrictors?

Looks like 5mg viagra is 10%-20% of the minimum recommended dose for viagra's original purpose

GP is talking about cialis (tadalafil), a completely different drug. It is dosed differently from viagra (sildenafil).

Thanks! I thought they were the same

Wasn't this class of medication originally for cardiovascular issues, and the whole ED mitigation was a happy marketable accident?

I vaguely recall an anecdote about athletes using it for performance improvement, and getting a slightly different stat buff

Tadalafil works well for getting more out of your workouts too (I take that). Gives you an overall feeling of well-being too (better than any cup of joe), I no-bullshit begin my day with it.
