Sildenafil is a popular erectile dysfunction (ED) tablet, taken by men who find it hard to get an erection on their own. It is the generic version of Viagra, which means it contains exactly the same active ingredient (sildenafil citrate) and works in the same way.
Since brand name Viagra and generic sildenafil both contain the exact same active ingredient, you can expect identical results from a 25mg-100mg dose of Viagra (the typical dose used for erectile dysfunction) to the same dose of generic sildenafil.
Viagra helps to maintain the erection after ejaculation and reduces the refractory time before a second erection can be obtained.
Currently, 100mg is the highest dose of sildenafil that's approved by the FDA for treating erectile dysfunction. It is okay to take a 100mg dose of sildenafil, but normally, you'll only be prescribed this dosage if you still find it difficult to get or maintain an erection after using a lower dose of sildenafil.
Sildenafil is an effective oral treatment for ED that produces a penetrative erection as early as 12 min and for most patients, within 30 min after dosing, and a duration of action lasting at least 4 h.
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.
Regardless of your dose or individual metabolism rate, Viagra usually wears off after 4-6 hours. Note that your erection should never last more than four hours. If it does, seek medical treatment.
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.
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.
Common physical causes of erectile dysfunction include heart disease, diabetes, nerve damage and high blood pressure. Hormonal issues, such as low testosterone, can also affect your level of sexual desire, which may stop you from getting an erection even with Viagra.
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.
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.
Unfortunately, no. It also won't prevent performance anxiety or make your penis larger.
Cialis has comfortably the longest effectiveness period of any erectile dysfunction drug on the market.
The 'as required' Tadalafil (generic Cialis) has an advantage over Sildenafil in that it lasts a lot longer – up to 36 hours (compared with 4-5 hours for Sildenafil). Some men prefer this as it allows for more spontaneity.
Sildenafil and other generic treatments like Tadalafil and Vardenafil are the cheapest erectile dysfunction pills available. These medications work the same way as branded treatments like Viagra, Cialis, and Levitra but since they aren't branded, they're usually cheaper.
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.
Who can take sildenafil. Most men aged 18 and over can take sildenafil for erectile dysfunction.
The FDA approved sildenafil 20 mg for the treatment of PAH and the 25 mg, 50 mg, and 100 mg dosages for the treatment of erectile dysfunction. Because sildenafil is the active ingredient in Viagra, the 20 mg dose can be prescribed off-label to treat ED (DailyMed, 2020).
The FDA has approved a daily pill called flibanserin (Addyi) — originally developed as an antidepressant — as a treatment for low sexual desire in premenopausal women. Addyi may boost sex drive in women with low sexual desire who find the experience distressing.
About a quarter of men said that erection problems started between age 50 and 59, and 40% said they started between age 60 and 69. Having chronic diseases and other risk factors matter with respect to ED, too.
Tolerance to sildenafil has been reported,[6] but so has efficacy for up to 4 years without requirement for dose increase. [7] It is possible that tolerance, if any, is due to progression in the organic pathology responsible for the ED.
