What happens if you take too much Viagra? If you take more than the recommended dose of Viagra, you can develop a condition known as priapism, which is an erection that lasts for longer than four hours.
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.
50mg is the standard starting dosage for sildenafil (Viagra). If 50mg does not produce the desired effect, or the effect does not last long enough, then taking two 50mg sildenafil tablets could be more effective. Doctors recommend trying the initial prescribed dose several times before deciding to change dosage.
Viagra 100mg is the most effective dosage, but it also has the greatest risk of side effects. You may want to try Viagra 100mg if the standard 50mg dose didn't work well enough for you, but you didn't get any serious side effects.
Get the timing right. Ideally, Viagra should be taken 30–60 minutes before you plan to have sex for best results. It needs time to work, so taking Viagra too close to the time that you need it may make it more difficult to get an erection strong enough for satisfying sex. Taking Viagra too early may do the same.
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.
Taking Viagra at this dosage also increases the risk of certain vision-related side effects, such as blurred vision, altered color vision and increased sensitivity to light. You should never exceed a 100mg dosage of Viagra. Don't take Viagra more than once a day, and never take two Viagra pills at a time.
You'll get the best results from the treatment if you use it correctly. Generally Viagra requires 30-60 minutes to take effect, therefore take Viagra at least one hour before you intend to have sex.
Viagra helps to maintain the erection after ejaculation and reduces the refractory time before a second erection can be obtained. These medications may be combined with various creams aimed at reducing sensitivity.
If you're using a lower dose of Viagra and find it isn't fully effective at treating ED (or, it doesn't seem to provide any improvement at all), consider talking to your doctor about moving up to a higher dose of the medication.
Structurally vardenafil (Levitra) is similar to sildenafil, while tadalafil (Cialis) is very different. 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.
Can you sleep with Viagra? The effects of Viagra last one to four hours, depending on factors such as your age, medical condition, and prescribed dose. Studies have shown that if you sleep after taking Viagra, you may experience a significant increase in nighttime erections.
In a study of over 3,000 men,⁵ one team of researchers found that participants who used Viagra recreationally were more than twice as likely to develop ED, so it's possible that recreational Viagra use may cause the problem it's intended to solve.
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 (sildenafil) is a prescription medication used to treat erectile dysfunction. Headache, flushing, and upset stomach are common Viagra side effects. These effects are usually mild and often resolve on their own. While rare, Viagra can cause an erection that lasts longer than 4 hours (priapism).
Viagra can stay in the system for up to 20 hours, but it takes about four to five half-lives for a drug to be fully eliminated. How long it is effective differs from person to person. FDA labeling states that Viagra is effective for up to four hours, but the effect at four hours is much less than at two hours.
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.
Viagra usually lasts around 4 to 6 hours, but It might last for a longer or shorter time depending on the person taking it. The only way to know exactly how long it will last for you is to try it and see for yourself.
