have a serious heart or liver problem. have recently had a stroke, heart attack or a heart problem – your doctor should carefully check whether your heart can take the additional strain of having sex. have low blood pressure (hypotension) have a rare inherited eye disease, such as retinitis pigmentosa.
This medicine can cause serious side effects in patients with heart problems. If you experience a prolonged or painful erection for 4 hours or more, contact your doctor immediately. This condition may require prompt medical treatment to prevent serious and permanent damage to your penis.
It's possible to develop long-term side effects from sildenafil treatment. In clinical trials,* long-term side effects, such as vision loss and hearing loss,† occurred at any time during treatment. However, the exact reason why these side effects occurred is not fully known.
However, because Viagra is a vasodilator, it helps open up blood vessels and arteries. You might think that this would actually help to reduce the risk of a heart attack, but, there have been reports of heart attack, stroke, arrhythmia and even death in men taking Viagra.
Viagra helps to maintain the erection after ejaculation and reduces the refractory time before a second erection can be obtained.
Regardless of your dose or individual metabolism rate, Viagra usually wears off after 4-6 hours. Note that your erection should never last more than four hours. If it does, seek medical treatment.
In controlled studies, Sildenafil 50mg was found to be effective in 74% of men with erectile dysfunction. As such, it's likely that you will experience success with this treatment.
Kegel exercises, or pelvic exercises, have proven to be effective in addressing erectile dysfunction, and it should be used as the first-line of treatment. The ischiocavernosus and bulbocavernosus muscles in the pelvic area surround the penis and are active during an erection.
Both brand name Viagra and its generic version sildenafil work by increasing blood flow to your penis. The corpora cavernosa — a pair of sponge-like areas of tissue inside your penis — relax, letting blood flow freely into the penis. This blood fills the tissue and causes your penis to expand and harden.
Minor differences in packaging aside, brand name Viagra and its generic counterpart sildenafil are exactly the same medication. If you have erectile dysfunction, both medications should produce noticeable improvements in your erections and sexual performance. The key difference, as we mentioned above, is price.
“Generic Viagra” is typically called sildenafil, and it has the same active ingredient and dosage as Viagra, but it is not sold under the brand name. These generic drugs are bioequivalent, which means they act the same way and produce the same results in the body.
If you are receiving therapy with sildenafil you should avoid the regular consumption of large amounts of grapefruits and grapefruit juice. Grapefruit can raise the levels of sildenafil in your body and delay the time it takes for the medication to work.
You may be more likely to experience symptoms such as dizziness, lightheadedness, fainting, flushing, headache, and heart palpitations. You should avoid or limit the use of alcohol while being treated with sildenafil, and use caution when getting up from a sitting or lying position.
Unfortunately, no. It also won't prevent performance anxiety or make your penis larger.
Nothing much would happen if someone without erectile dysfunction took Viagra, although they might think they feel better psychologically. But it would make a difference if you took it along with other drugs. Cocaine, marijuana, ecstasy, alcohol, nicotine, crystal meth - they all can cause erection problems.
When used in women, Viagra is thought to raise blood flow to the genitals so that there's more sensitivity and stimulation. Studies have shown that Viagra may provide a benefit for women having difficulty with sexual arousal — since it may help them respond better to sexual stimulation.
About a quarter of men said that erection problems started between age 50 and 59, and 40% said they started between age 60 and 69. Having chronic diseases and other risk factors matter with respect to ED, too.
While there is no definite age at which male ejaculation ceases, it has been suggested that it may happen when a man reaches his late 40s or early 50s. It is important to note, however, that this is not a universal rule and some men may continue to ejaculate at a later age.
There is no universal set time for the length of sexual activities or how long a penis should remain erect. Typically, an average erection may last from a few minutes to roughly half an hour. However, this can vary significantly due to the many factors that can affect erection duration.
The biggest difference between Viagra and Cialis is the amount of time their effects last. Viagra remains effective for 4 to 6 hours, which offers ample opportunity to have sex on multiple occasions if you wish. However Cialis typically allows you to achieve erections for up to 36 hours after taking a tablet.
Swallow tablets whole with a drink of water or juice (but not grapefruit juice). For erectile dysfunction, it's best to take sildenafil on an empty stomach. It may take longer to work if you take it with food.
