In this article, we will be explaining what Viagra is, how it helps to treat your erectile dysfunction, how long it takes to work, how long it will last and what you should do if your erection lasts more than 4 hours.

What Is Viagra and How Does It Treat Erectile Dysfunction?

Viagra is a highly effective oral medication pill prescribed to treat male erectile dysfunction (ED). 


Viagra is able to treat erectile dysfunction due to its main ingredient sildenafil, a phosphodiesterase type-5 (PDE5) inhibitor. Phosphodiesterase type-5 (PDE5) is an enzyme that regulates the flow of blood out of the penis. By inhibiting and slowing PDE5, Viagra is able to relax the muscles and the walls of the blood vessels. This then allows the blood to flow more freely into the penis, which makes it easier to create and maintain an erection. 


How Long Does It Take For Viagra To Work?

Viagra takes between 30 to 60 minutes to work. It is possible that Viagra might only kick in for you after 2 hours. 


Despite its reputation as a miracle pill, Viagra will not cause you to get an erection immediately after taking it. You will need to be sexually aroused to get hard. Keeping yourself relaxed and comfortable will help Viagra kick in much quicker. 


How Long Does Viagra Last For?

Viagra is the most effective during the first 2 to 3 hours before it begins to wear off. It is possible that Viagra can last up to 5 hours or longer, but this will depend on factors like the dosage you were prescribed and your body's metabolism rate. 


In a study done by the Journal of Sexual Medicine, researchers found that it was possible for the effects of Viagra to last for a maximum of 12 hours. However, it is unlikely that this would be the case for everyone. This is because after 3 to 5 hours, the effects of Viagra will begin to taper off. 


It is unlikely that Viagra will work immediately after you orgasm as your body isn't ready to have another erection so soon. This duration of time when you are unable to get hard is called the refractory period. After resting for a while, it is possible that you can get another erection again if you are aroused and within the timeframe when the Viagra is still effective. 


How Long Viagra Will Last Will Depend On The Person And Other Factors 


How long Viagra will be able to last for you will depend on a host of factors. This can include your age, your diet, what medications and supplements you're on, the dosage of Viagra prescribed to you and whether you've been drinking before taking Viagra.


Viagra comes in three different doses: 25mg, 50mg and 100mg. It is possible that Viagra can last longer for you if you are prescribed a higher dose. 


Viagra can also last longer in older gentlemen as it takes a longer time for their bodies to process the medication. Men with medical conditions like kidney or liver disease are also more likely to have Viagra last longer for them due to their metabolic and liver taking longer to metabolize the medication.  


If you want Viagra to last longer for you, you should take Viagra on an empty stomach. This is because fats from your meal can affect how fast your body can absorb the medication and can affect how much of the medication is being able to be absorbed. 


Can I Take More Viagra To Make My Erection Last Longer?

No. 


It is unsafe for you to take more Viagra than prescribed in an attempt to make your erection last longer. 


As mentioned earlier, the effects of Viagra will only last up to 12 hours. However, it will still take the body 24 hours to metabolize it and have it safely leave your system. 


If you take more Viagra than prescribed within a 24 hour period, you could potentially increase the amount of Viagra in your body to an unsafe level. This could increase your chances of experiencing side effects, with some of them being more serious like priapism. 


Priapism is a prolonged erection that lasts for more than 4 hours and does not go away. If this happens to you or your erection begins to feel uncomfortable, you should contact your doctor immediately. 


You should also not mix Viagra with any other erectile dysfunction medication (like Cialis or Avanafil).


Other Potential Side Effects Of Viagra

While taking Viagra is generally safe, you might experience some mild side effects after taking it like: 


- Headaches

- Dizziness

- Nausea

- Chest Pains

- Flushing

- Indigestion

- Nasal Congestion


While these side effects will eventually subside and go away after a few hours, they can also be remedied at home. 


Side effects like headaches, dizziness and flushing can be reduced by resting and lying down. Avoid drinking alcohol to prevent exacerbating these side effects and turn down the lights to reduce the severity of your headache. 


If you experience indigestion after taking the medication, try taking it with a light snack or meal the next time you take it. However, this might cause Viagra to take a longer time to get absorbed by your body and kick in, so do take into consideration and plan ahead. 


It is possible that side effects like headaches, nasal congestion, flushing and indigestion could be caused by taking a higher dosage of Viagra. If these side effects become unbearable, it is worth consulting your doctor to lower the dose of Viagra prescribed.
