Serious Question: If you take viagra prior to sleep would nocturnal erections induce priapism?

If you take say 25mg's of viagra, and have nothing wrong with you ED related. And then you go to sleep after ingesting the pill, would the natural nocturnal erections cause a priapism since viagra is in your system? Or would the erections subside like normal after nocturnal erection episodes even with viagra in your system?

Please only answer if you truly know the answer, or can ask a medical doctor (I'm not looking for hearsay) specifically a urologist. Thanks.
I take it for performance anxiety some times.. but back to the question please, i'd really like to know, since viagra is usually taken prior to bed time anyway.

You are going to end up with ED if you keep messing around with Viagra. You have no good reason to be taking it.  (+ info)

Can a guy take 25 mg of trazodone and be safe of getting priapism?

Doctor prescribed me Trazodone for sleep, im afraid of Priapism though, i took 25 mg and it did help me sleep, but what are the chances to have priapism using this drug?

although it is a side effect of the drug it is not a common one. I wouldn't worry about it but if does happen go to the ER. here is all of the info on the drug from a website I use for school (i'm a nursing student)..oh and the drug will take a couple of weeks to work so don't stop taking it yet and if you decide to stop consult your doctor before doing so.

How can one get rid of priapism?

I can't even go to the grocery store without getting a lot of curious looks and smiles.

Its a medical job, not one you can deal with.
The first step for the patient with priapism of less than four hours duration is the use of decongestant medications. These medications include drugs such as pseudoephedrine and terbutaline, which may act to decrease blood flow to the penis and is very successful in early cases. If the erection does not respond, one then proceeds with aspiration. The longer the condition goes without treatment, the worse the prognosis.  (+ info)

How does someone know they have a priapism in their sleep?

Does it really hurt? Or could someone have it, and never know it?

Why are you always worried about priapism, it can occur in some rarely cases when taken with some ED meds.

It's not normal that you can sleep while having a priapism, you would wake up with pain and sure couldn't sleep anymore.

When the erection is lasting for 4 hours or more, than it can be that it hurts. But nobody can give you an answer about it, because most of us didn't expect priapism.

When priapism is not treated after 4 hours, than you lose your potency forever and are impotent.

But when you seek medical attention, they can help you.

Forget about it and don't be worry!!!!  (+ info)

How would you know you have Priapism? Does priapism hurt?

Like a dull annoying ache? An excruciatingly pain? Could you have priapism in sleep and not ever know it?

Are you trying to be funny?

Priapism is a painful erection generally lasting longer than four hours. Obviously, you would be aware of it if you had it. Often, the only way to treat priapism is to go to the doctor and have him drain the blood out of the penis with a needle.  (+ info)

what is the chance of impotance after three days of priapism?

my husband had suffered from priapism for three days when he was around 18 because of medications for his depression. now that we are ready to have children we are having some complications. what would his fertility rate be at and what can we do to help?
by the way... he did have a painful erection the whole 3 days... i was hoping i wouldnt have to add that part...

Priapism can cause impotence. If your husband has normal erection...then no need to do anything.
If there is impaired erectile function, then he shouldn't have fertility problems...but u need to seek specialist help for other assisted methods of conception.  (+ info)

If you fall asleep with Viagra and have a priapism, will you know it?

Is it going to hurt? Or will you wake up with a non-working penis?

this question's been all over the place lately. I never heard of anyone having a priapism while asleep. I don't know what you must see in your dreams in that case, Adriana Lima, Scarlet Johanson and the Olsen sisters at the same time??  (+ info)

how can a doctor tell if you have had priapism in the past?

Im 21 years old and have been on zoloft for 8 years. I believe I have had this condition in the past due to taking zoloft. I believe I have had it multiple times. It is getting tougher to get an errection
the problem started as early as 17

It is really hard to answer your questions without a much better history.

I presume you started taking zoloft for depression or something like that. So while you were on it you got frequent erections that did not go away? Even after you masturbated your erection stayed???

Priapism can be a side effect of zoloft though it is not common.

The doctor can tell you have had priapism only by taking a medical history from you. If you tell him you had frequent and painful erections that would not go away then that is how he will know. He cannot just look at your penis and work it all out by looking.

So now you have something of the opposite problem - that also could be an effect of zoloft. You should always talk to a doc about side effects of meds - perhaps he can change your script and help you better.

Is it true that if you have to ask if you had a priapism you probably didn't have one?

I assume you'd KNOW you have a priapism? Must be painful?

Priapism is a rare condition that causes a persistent, and often painful, penile erection.


Priapism is drug induced, injury related, or caused by disease, not sexual desire. As in a normal erection, the penis fills with blood and becomes erect. However, unlike a normal erection that dissipates after sexual activity ends, the persistent erection caused by priapism is maintained because the blood in the penile shaft does not drain. The shaft remains hard, while the tip of the penis is soft. If it is not relieved promptly, priapism can lead to permanent scarring of the penis and inability to have a normal erection.

Causes and symptoms

Priapism is caused by leukemia, sickle cell disease, or spinal cord injury. It has also been associated as a rare side effect to trazodone (Desyrel), a drug prescribed to treat depression. An overdose of self-injected chemicals to counteract impotence has also been responsible for priapism. The chemicals are directly injected into the penis, and at least a quarter of all men who have used this method of treatment for over three months develop priapism.


A physical examination is needed to diagnose priapism. Further testing, including nuclear scanning or Doppler ultrasound, will diagnose the underlying cause of the condition.


There are three methods of treatment. The most effective is the injection of medicines into the penis that allow the blood to escape. Cold packs may also be applied to alleviate the condition, but this method becomes ineffective after about eight hours. For the most serious cases and those that do not respond to the first two treatments, a needle can be used to remove the blood. The tissues may need to be flushed with saline or diluted medications by the same needle method. That failing, there are more extensive surgical procedures available. One of them shuts off much of the blood supply to the penis so that it can relax. If the problem is due to a sickle cell crisis, treatment of the crisis with oxygen or transfusion may suffice.


If priapism is relieved within the first 12–24 hours, there is usually no residual damage. After that, permanent impotence may result, since the high pressure in the penis compromises blood flow and leads to tissue death (infarction).

We see this often in patient with serious trauma.  (+ info)

I fell asleep with viagra in my system, did I have priapism?

The doctor allowed me to try 50mg of Viagra, I actually took 25mg's. I didn't end up having sex that night, and fell asleep couple hours after ingesting the pill. I woke up a few hours after that with an erection in my sleep. Did I have a priapism?
He gave to me for perf. anxiety.
