While rare, Viagra can cause an erection that lasts longer than 4 hours (priapism). This can result in permanent damage if left untreated. Vision changes are also possible.
Most side effects of Viagra are mild and go away quickly as the drug wears off. But in rare cases, some serious side effects can have long-term complications. For example, Viagra can cause prolonged erection. If not treated, this can lead to permanent erectile dysfunction.
Daily Use of Sildenafil
It is considered safe and effective and, for most people, it causes only mild side effects. Those side effects could include headaches, dizziness and rashes, among other symptoms. If you experience any side effects, it's a good idea to talk to a healthcare provider.
The short answer is yes; you can take Viagra or its generic form, sildenafil, every day. Whether you need to or should, depends. Since each person is different, you should consult with a doctor about what's best for you. They can discuss dosage and frequency.
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.
Sudden vision loss warning: This drug can cause sudden vision loss in one or both eyes. This can be a sign of a serious eye problem. If this occurs, stop taking sildenafil and call your doctor right away. Sudden hearing loss warning: This drug can cause hearing loss, tinnitus (ringing in your ears), or dizziness.
Dosage and strength for erectile dysfunction
Sildenafil tablets for erectile dysfunction come in different strengths ranging from 25mg to 100mg. The usual dose is 50mg, when you need it. Do not take it more than once a day. The dose can be increased to 100mg or decreased to 25mg depending on its effect.
Taking Sildenafil 100mg
The effects of Sildenafil 100mg do not last longer than the 50mg dosage, but they tend to be stronger. This means that side effects can be more pronounced as well. Side effects associated with Sildenafil include headache, facial flushing, nausea, dizziness and stuffy nose.
Alcohol (Ethanol) sildenafil
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.
Sildenafil has been associated with rare instances of clinically apparent liver injury.
Viagra helps stimulate erections by increasing levels of cGMP -- which is also involved in blood clotting. Therefore, by increasing levels of cGMP, Viagra may actually increase the risk of blood clots, according to the researchers.
Can Viagra Cause ED? Because Viagra only works by increasing blood flow to your penis, it doesn't have any harmful effects on your penis. Using Viagra won't damage your penis or vascular system, or cause any “depletion” of your ability to function in bed naturally.

Sildenafil (brand name Viagra, or affectionately nicknamed “the little blue pill”; see Important Safety Information) is a highly effective medication to treat erectile dysfunction. However, there is something it can't do. Viagra does not make your penis bigger. No pill does.
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. It is also worth noting that a person does not need an erection to achieve orgasm.
Unfortunately, that's one of many dangerous logical fallacies when it comes to ED medications: taking two pills isn't going to make your erection twice as hard, or twice as large — it's just going to cause your risk of adverse effects to double.
The highest recommended Viagra dose for treating erectile dysfunction (ED) is 100 mg per day, according to the drug's manufacturer. Doses of 150 mg or 200 mg would be considered off-label use.
The effects of taking 100 mg of Viagra can last for up to 4 hours after taking the drug. However, the strength of these effects is weaker at 4 hours than 2 hours after taking Viagra. As the concentration of Viagra in the blood typically peaks 60 minutes after taking the drug, the effects are strongest around this time.
Sildenafil does not improve erections in young healthy men. Sildenafil should not be given to young healthy men to improve their erections and patients should be advised against recreational abuse of the drug.
Thiazides are the most common cause of erectile dysfunction among the high blood pressure medicines. The next most common cause is beta blockers. Alpha blockers tend to be less likely to cause this problem.
Never take more than 100 mg of Viagra in a 24-hour period. Too much Viagra can cause severe headache, low blood pressure, and orthostasis (drop in blood pressure when standing) that can lead to fainting. Higher doses can also cause priapism, a painful erection that lasts longer than 4 hours.
Almost all cases of erectile dysfunction are treatable, and treatment can lead to better overall physical and emotional health for nearly every patient as well as improve intimacy for couples.
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.
