Generic Viagra, or sildenafil citrate, works the same as Viagra, but at a lower cost. While Pfizer still manufactures the “little blue pill,” other companies, globally and in the United States, make sildenafil. It may look different, but it's still an effective treatment for ED.
Minor differences in packaging aside, brand name Viagra and its generic counterpart sildenafil are exactly the same medication. If you have erectile dysfunction, both medications should produce noticeable improvements in your erections and sexual performance. The key difference, as we mentioned above, is price.
By controlling the enzyme, sildenafil helps to maintain an erection after the penis is stroked. Without physical action to the penis, such as that occurring during sexual intercourse, sildenafil will not work to cause an erection.
Dosage and strength for erectile dysfunction
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. Take sildenafil up to 4 hours before you want to have sex.
Because these drugs have the same active ingredient (sildenafil), they work the same way in the body. The key differences between Viagra and sildenafil are the dosages available and the price of the drugs, which may differ significantly. Viagra is to erectile dysfunction, what Kleenex is to the common cold.
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.
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.
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.
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.
There are several reasons Viagra and other ED drugs might not work effectively as treatments for erectile dysfunction. These include using Viagra incorrectly, taking a low dose of Viagra and using Viagra to treat ED that's caused by something other than poor blood flow.
The most common adverse reactions reported in clinical trials ( > 2%) are headache, flushing, dyspepsia, abnormal vision, nasal congestion, back pain, myalgia, nausea, dizziness, and rash.
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.
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.
If your doctor has given you the correct prescription and you take it as directed, 20 mg of sildenafil should work without a problem.
Sildenafil starts working within 30–60 minutes. Some men find that it works even faster. You should take sildenafil between 30 minutes and four hours before sexual activity. The medication usually stays in your system for 4–5 hours (Zucchi, 2019; DailyMed, 2020).
The effects of Viagra can last 4 to 8 hours, depending on the individual person and the dose you take. In fact, some people may experience more than one erection during this time.
Sildenafil increases serum testosterone levels by a direct action on the testes. Andrology.
The bottom line. Sildenafil (Viagra) is by far the most affordable medication for ED and the one with the longest safety record. It's good for occasional use, but be sure to take it on an empty stomach. Tadalafil (Cialis) lasts longer, making it useful if you have a more active and regular sex life.
Technically, Viagra, or its generic form, sildenafil, can be taken daily, but it's not always the best choice.
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.
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.
You should never increase your dose, double your dose, or change how you take ED medication without the advice of your healthcare provider. If Viagra isn't working the way you'd like or you're experiencing side effects, speak to your healthcare provider.
