Side effects of Viagra include headache, nausea, dizziness, vision loss, nasal congestion, muscle pain and back pain. Although uncommon, Viagra can also cause more serious side effects such as priapism (prolonged, painful erection) and vision problems (mostly in older men)3.
Viagra doesn't stop your erection going down after you ejaculate, so you'll likely lose your erection after you do. If you are having trouble orgasming too early then you may need separate treatment for premature ejaculation.
Long term usage of Viagra has been shown to cause dyspepsia (indigestion) and can lead to stomach upset such as diarrhoea, gastritis, vomiting and abdominal pain. Erectile dysfunction is really common. But thankfully there are plenty of easy treatments that can help.

Viagra is only recommended to be taken once per day. This means that if you're planning on engaging in sexual activity more than once throughout the day, you shouldn't take a pill every time. And if you take a pill and it doesn't work for you — don't double up and take another one.
Viagra is a brand-name prescription drug that's approved to treat erectile dysfunction (ED). With ED, you're unable to have or maintain an erection. Viagra is approved for this use in males ages 18 years and older. Viagra contains the drug sildenafil.
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 good news is that sildenafil (the active ingredient in Viagra) isn't linked to physical addiction, meaning you won't develop a physical dependence on it or develop withdrawal symptoms if you stop using it suddenly.
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.
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.
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.
Viagra does not make your penis bigger. 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.
Prescription Options for Longer Erections
There are four FDA-approved prescription medications to treat erectile dysfunction: Sildenafil (Viagra), tadalafil (Cialis), vardenafil (Levitra), and avanafil (Stendra).
When you have trouble achieving or maintaining an erection with a partner, it can be embarrassing – especially if it is happening for the first time. When something like this happens, it is easy to close yourself off and wallow in your worry and self-pity.
There are multiple reasons why erections suddenly go away, including physical problems, psychological problems, and issues with medication or lifestyle. Erection problems aren't uncommon, but if they are happening frequently over a period of time, it can affect a man's self-image, self-esteem, and relationships.
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.
When you take Viagra for the first time you might get some side effects. These can include flushing of the skin, dizziness, or headaches. These side effects are normal as the blood vessels in your body are adjusting to the effects of Viagra. It usually takes a few hours before these side effects go away.
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.
Viagra is designed to improve your physical performance during sex — that is, your ability to get and maintain an erection. However, it isn't associated with any significant increase in your level of sexual interest, sexual arousal or your sex drive in general.
In women, Viagra can increase blood flow to the clitoris and the labia of the vagina which may increase lubrication and sensation. This may help some women with sexual arousal and orgasm, especially in women after menopause with vaginal dryness.
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.
