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.
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 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.
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.
Conclusion: Men with erectile dysfunction treated with 100-mg compared with 50-mg sildenafil may be more likely to achieve a greater improvement in erectile function and, within the first 2 weeks, completely hard and fully rigid erections, with little or no greater risk to tolerability.
This medicine usually begins to work for erectile dysfunction within 30 minutes after taking it. It continues to work for up to 4 hours, although its action is usually less after 2 hours.
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.
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 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 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.
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.
Such erections were achieved as quickly as 12 min and, for most patients (71%), within 30 min. This finding reflects the time to peak plasma concentration of sildenafil after oral dosing (30–120 min) [3] and is consistent with the results of other clinical trials [5–11].
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.
As with all medication, you should take the recommended dose of sildenafil prescribed to you by your healthcare provider, and no more. You also shouldn't take sildenafil more than once every 24 hours. Your healthcare provider will likely start you on a 50 mg dose of the medication to test how well you respond to it.
Take Viagra 30-60 Minutes Before Sex
The precise amount of time required for Viagra or generic sildenafil to start taking action varies based on a variety of factors, from your diet to your personal drug metabolism.
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.
Why You're Not Getting All the Way Hard. Erectile dysfunction's mechanism is quite simple, but the underlying cause could be a myriad of reasons, from poor diet and exercise habits, diabetes or heart disease, to low self-esteem, depression or anxiety.
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.
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.
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.
Generally, there are three doses of sildenafil that are prescribed: 25mg, 50mg and 100mg. Your healthcare provider will assess which dose is right for you. Oh, and you should never take more than a single dose at once. Not only can this increase side effects, it can lead to a condition called priapism.
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.
