How Long Does Viagra Last in Your System After Taking it? How long does it’s Half-Life Last?

Viagra has a half-life of about 4 hours, on average. This indicates that four hours after taking a dose, your body will have eliminated fifty percent of that dose. In the majority of instances, approximately five half-lives are required for the body to completely eliminate a drug from the system. Because of this, it is possible that it will take about twenty hours for Viagra to be eliminated entirely from your body. However, as your body rids itself of the drug, you may find that it is no longer effective.

Interaction With Viagra

When combined with nitrates, sildenafil can result in a dangerously low blood pressure reading for the patient. A significant drop in blood pressure can cause symptoms such as dizziness and fainting, and in rare cases, it can even lead to a heart attack or stroke.

Suppose you are also being treated for an enlarged prostate/BPH or high blood pressure with an alpha blocker medication (such as doxazosin, Tamsulosin). In that case, your blood pressure may drop too low, which may cause you to feel dizzy or even pass out. 

The elimination of sildenafil from your body can be influenced by other medications, which can have an effect on how well sildenafil works. Antifungals known as azoles, such as itraconazole and ketoconazole, and antibiotics known as macrolides, such as clarithromycin and erythromycin, as well as HIV protease inhibitors known as saquinavir, mifepristone, rifampin, and ritonavir, are a few examples of these types of medications.
