Viagra is a medication that helps you to get and keep an erection, so it can make you last longer in bed if you're finding it difficult to stay erect during sex. However, Viagra does not help you last longer if you're orgasming faster than you want to.
NO, Viagra doesn't have any noticeable impact on your sex drive, sexual stimulation or general level of interest in sex. AND NO, it won't trigger a sudden erection right after you take it or prevent you from having sex normally.
Because 100mg is the highest dose available, you should never 'double up' on tablets or take more than one in 24 hours. Sildenafil 100mg is the highest safe dosage you can take – if it is ineffective, you should try another ED treatment.
Erectile dysfunction (ED) medications that can be cut in half. The most common ED medications can be safely split. This includes: Sildenafil (Viagra)
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.
Viagra doesn't start working immediately after taking it, as the medication needs time to be absorbed into your blood. For most men, it takes around 30 minutes before you start to feel the effects of Viagra. 12 minutes after – One study has shown that some men got an erection just 12 minutes after taking Viagra.
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.
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).
Low testosterone levels
Viagra cannot replace testosterone levels, so when those levels drop too low, Viagra cannot stimulate enough blood flow into the penis to make up for the drop in hormone levels. That results in Viagra no longer working as well as it should or failing to work at all.
What happens if a woman takes Viagra? Just as Viagra helps improve blood flow for an erection, it may improve blood flow in the female reproductive parts. When this happens, it may cause more sensitivity and stimulation, causing the person taking it to become more aroused.
The bottom line. It's best to avoid consuming alcohol while taking ED medications like Viagra: Not only can alcohol counteract the medication's effects, but it can also worsen side effects, like flushing and headaches.
Viagra is a useful form of treatment for erectile dysfunction. It is best to take the drug around 60 minutes before sexual activity, and its effects can last up to 4 hours. Viagra cannot cause an erection if there is a lack of sexual arousal.
You may be wondering if there are ways to help the medication work even faster, like chewing or crushing the tablet and dissolving it under your tongue. However, it isn't made to work that way and should be swallowed whole.
