How long does Viagra stay in your system?
As a general guideline, it can take nearly a day for Viagra to exit your system due to its half-life. The half-life of a medication refers to the time taken for the initial dosage to halve in your body. Viagra has a half-life of approximately four hours, reflecting its usual effective duration. A medication generally needs four to five half-lives to clear from the body entirely, so Viagra is typically eliminated after around 16 to 20 hours.
Various factors, such as age, other medications, and existing health conditions can impact the duration of Viagra in your system. For example, for older individuals (those age 65 and older), Viagra might remain in their system longer, so a lower dose is initially recommended.
How much Viagra (sildenafil) is too much?

Headaches usually go away on their own, but consult one of our trusted doctors if they become severe or persistent.
