Also, certain people might experience extreme side effects of sildenafil and thus, can be unsuitable for some.

Sildenafil comes in various strengths like in dosage of 25mg, 50mg, and 100mg. 50mg is ideally considered as the usual dose to be taken only once a day. However, if prescribed by a doctor, one can even take dosages of 25mg or even 100mg according to one’s desired effect of the drug on the body.
Why Does Sildenafil Last This Long?
The maximum effect of the drug is observed between 30 minutes to 2 and a half hours after one takes it. Sildenafil remains effective and lasts in the body for about four hours. Despite this general notion, several factors can influence and change this timeframe.
If one’s body is quick in absorbing, sildenafil might get absorbed extremely quickly in about 20 – 40 minutes. When consumed on an empty stomach, it might reach the peak levels inside the body after an hour. However, if one has recently eaten, this might take a bit longer. Whatever may be the case, sildenafil will last for about 3 – 5 hours and will be entirely gone from the body by the end of the day.
Sildenafil has a half-life of only four hours. This symbolizes that after about four hours inside the body, sildenafil leaves the bloodstream. However, for certain men, the effect can last even up to 10 hours, but this is a rare possibility.
After 1 hour, the concentration of the drug is said to be found maximum inside the body. The drug is in high concentration in the bloodstream which can potentially increase further by another hour if the person has eaten food before taking sildenafil. One will not find any traces of the drug in the bloodstream after complete 24 hours as none of the substances in sildenafil remain active for such a long time.
Although sildenafil is an effective medication for erectile dysfunction, it too can certainly cause side effects. Some of the most common side effects of taking sildenafil are headaches, dizziness, blurred vision, nausea, dyspepsia (indigestion), etc.
Conclusion
Sildenafil is a drug popularly prescribed for ED patients to enhance their erectile function. It reaches its maximum effect inside the body within one hour. One can remember that it kicks in faster when taken on an empty stomach. It can remain effective for about 3 to 5 hours and thus, is said to last for 4 hours inside one’s body.
Sildenafil makes it easier for ED patients to have a proper erection. The effects of the drug will gradually reduce over time and will be fully gone within 24 hours. Care must be taken to never take more dosage of the drug than prescribed.
