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.
4/13 (31%) responders refused to continue treatment due to adverse effects.In conclusion, sildenafil at doses of up to 200 mg is an effective salvage therapy for 24.1% of previous sildenafil non-responders but is limited by a significantly higher incidence of adverse effects and a 31% treatment discontinuation rate.
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.
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.
Sildenafil (Viagra) for ED (erectile dysfunction) lasts about four hours. It reaches peak concentrations in about an hour, so it's best to take sildenafil 30 to 60 minutes before sex.
That's because the higher the dose of a medication, the higher the risk of side effects. Sildenafil is no exception. Some sildenafil side effects include headache, redness in the face, changes in vision, stuffy nose, muscle aches, back pain, nausea, dizziness, and rash.
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.
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.
Adults—5 or 20 milligrams (mg) three times a day. Each dose should be taken about 4 to 6 hours apart. Children—Use and dose must be determined by your doctor.
Although it can be taken with or without food, Viagra tends to work best when taken on an empty stomach. So, to maximize its effects, try to take it separately from meals.
Sildenafil is in a class of medications called phosphodiesterase (PDE) inhibitors. Sildenafil treats erectile dysfunction by increasing blood flow to the penis during sexual stimulation. This increased blood flow can cause an erection.
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 can be prescribed in 20 mg, 40 mg, 60 mg, 80 mg, and 100 mg doses. 100 mg is the maximum dosage available for Viagra and sildenafil for a reason, and your healthcare provider is unlikely to prescribe more than that for you.
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.
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.
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.
Sildenafil usually lasts for 4-6 hours at full potency. You'll continue to get some effect while there's some in your bloodstream, though, so it can still produce results past that point. It all depends on your health, age, dosage, and sexual activity.
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.
Speak with your healthcare provider about a different dose
If Viagra isn't working for you, you might need a higher dose. But don't experiment on your own: Always speak with a healthcare provider about dosage changes and never take more than one dose of Viagra in any 24 hour period.
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.
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.
Taking More than the Recommended Dose of Sildenafil
Actually, not at all. While you may think that taking more than your prescribed dose of sildenafil could increase the firmness of your erection or make you last longer, that's not true. In fact, it could just increase potential side effects.
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.
Introduction: Sildenafil citrate 50 mg is the recommended starting dose for men with erectile dysfunction (ED); however, most men are later titrated to sildenafil 100 mg for improved efficacy.
