Can you take viagra every day?

Are There Benefits to Taking Viagra Daily?
Taking Viagra or similar medications daily can benefit your urinary and sexual health. Some people may experience mild side effects that typically go away with time.
Since 1998, Viagra (sildenafil) has been used for treating erectile dysfunction (ED).
It’s available by prescription for males ages 18 years and older. Side effects are not frequent and usually not severe.
But can you take Viagra daily, and what’s the benefit?
We spoke with Dr. Irwin Goldstein, a primary researcher on the landmark study of oral sildenafil in the 1990s, to answer this and other questions.
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. They’ll consider your overall health and any other medical conditions you are being treated for.
Viagra may not be safe for you if you have high blood pressure, kidney problems, or a heart condition, for example. It also may interact negatively with some other medications.
Viagra should only be taken once a day.
Goldstein, director of San Diego Sexual Medicine at Alvarado Hospital and clinical professor of surgery at the University of California San Diego, explained to Healthline why blood flow to the penis is important.
“The penis is a unique organ. Arterial blood goes through other organs all the time, but the penis doesn’t have that.
During the day, there’s very little blood flow in the penis. Only during erections is there blood flow. All the other organs are getting the 100 mm of oxygen all day and night, but the penis doesn’t.”
“The penis only gets arterial blood flow during erections and during sleep. A routine night situation would involve 3 or maybe 4 or 5 hours of erection time, depending on how many hours the person slept. So from the perspective of the penis, sleep is the real time when oxygenation occurs.”
For people with ED, a daily dose of Viagra can improve oxygenation for the penis by improving the quality of nighttime erections.
Goldstein noted that having good nighttime erections can help “prevent the scarring of the penis” that normally occurs with age. Controlled studies have shown this going back to 2000.
Ultrasound gives us the ability to assess the degree of scarring in an individual, Goldstein said.
“Taking a PDE5 inhibitor every night can magnify the night erections and increase the chance of oxygenation, which increases the chance of getting rid of that scar tissue.”
How does Viagra work?
Viagra and Cialis (tadalafil) are both phosphodiesterase type 5 (PDE5) inhibitors.
This class of drugs works to relax the smooth muscle in the blood vessels of your penis, which increases blood flow and helps you have and keep an erection.
