Viagra contains the drug sildenafil. It belongs to a class of drugs called phosphodiesterase type 5 (
The active ingredient in Viagra is sildenafil citrate, which is a phosphodiesterase type 5 inhibitor (PDE5i). The inhibitor blocks the enzyme PDE5, which prevents relaxation of smooth muscle tissue.
Viagra is primarily an erectile dysfunction medication and does not directly impact time to ejaculation.
Viagra can cause some serious side effects. These can include an erection that will not go away (priapism), sudden vision loss in one or both eyes, and sudden hearing decrease or hearing loss. Some men have also experienced heart attack, stroke, irregular heartbeats and even death after taking Viagra.
Although it can be taken with or without food, Viagra tends to work best when taken on an empty stomach. So, to maximize its effects, try to take it separately from meals.
Viagra does not stimulate you sexually, it can only help you get an erection once you're already aroused. Because Viagra only helps you to get an erection by improving blood flow to the penis, it doesn't force you to get an erection, so it won't work unless you're sexually stimulated.
Common physical causes of erectile dysfunction include heart disease, diabetes, nerve damage and high blood pressure. Hormonal issues, such as low testosterone, can also affect your level of sexual desire, which may stop you from getting an erection even with Viagra.
Some people may choose to take medications like Viagra off-label to try enhancing sexual performance, even when they don't have ED. Taking Viagra recreationally can have serious side effects — like causing ED. You should always talk with your healthcare provider before taking a medication like Viagra.
We know that Viagra works in men by increasing the blood flow to the penis. In women it's thought that Viagra could increase blood flow to the female genital area, increasing lubrication and aiding orgasm.
A penile erection can normally last anywhere from a few minutes to about half an hour. On average, men have five erections a night while they're sleeping, each lasting about 25 to 35 minutes (Youn, 2017).
The Mayo Clinic's website attributes delayed ejaculation to a number of possible sources. Physical factors can include medications (particularly antidepressants such as Zoloft and Prozac), as well as any operations, injuries, infections or birth defects that may be impeding your performance.
No pill does. It can help you get and maintain a firmer erection that lasts longer, though. To put it another way, sildenafil and other ED medications make the most of what you've got. They won't magically endow you with more length or girth permanently.
If Viagra isn't achieving the results you desire, you can make changes to make Viagra more effective. Taking the pill at the right time, not taking it on a full stomach, and avoiding taking it with drug or alcohol use all might improve the effectiveness of the medication.
Although many people speculate that Viagra can cause heart attacks, there is no official documented evidence of such an adverse event. However, men with existing heart conditions and those who are taking heart medications should avoid or exercise caution when taking erectile dysfunction drugs.
Vardenafil (Levitra) is almost 10 times more biochemically potent than sildenafil, therefore a lower dose is needed to facilitate the penile erection, potentially resulting in less side effects. Selectivity is the ability of the drug to attach to the specific enzyme PDE 5 found in penile tissues.
Is There a Way To Tell if a Man is Taking Viagra? Wondering if your man is taking a pill to keep up his energy in bed? You could check his medicine cabinet, send an email to his doctor asking what prescription drugs he's on, or have his blood tested.
There could be a number of contributing factors for this. Your partner may be curious about the extent to which his performance will be enhanced; he may be experiencing peer pressure; or if he has had too much to drink, he may take the medication to combat the negative impacts of alcohol on performance.
Women can take medications such as Addyi (flibanserin) and Vyleesi (bremelanotide injection) to help increase sexual arousal. Other aids that may help include massage, lubricants, and relaxing with a bath or meditation before sex.
There's no specific age at which erectile dysfunction (ED) starts. But ED is much more likely after the age of 50. Although you can't change your age, you can take steps to improve your overall physical health and prevent weight gain, heart disease, and diabetes.
Erectile dysfunction (ED) medications that can be cut in half. The most common ED medications can be safely split. This includes: Sildenafil (Viagra)
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.
Viagra may not work the first time you use it. It can take up to 8 separate doses of Viagra before you see the full effect.
An increase in sildenafil dose from 50 mg to 100 mg was associated with a higher proportion of completely hard and fully rigid erections and a higher rate of SSI during the initial attempt using the higher dose, improvements that were statistically significant in the larger study.
