How Viagra Works
How Does Viagra Work?
Viagra works by relaxing the blood vessels in the penis, allowing blood to flow into it more easily, helping it get erect. The active ingredient is called sildenafil, which is a PDE5 inhibitor.
PDE5 inhibitors increase blood flow to the penis when a man is sexually aroused.
You Still Need Sexual Desire
Viagra won’t give you an automatic and instant erection. To get an erection you need to feel the sexual desire in the first place, Viagra will then make it more likely that the desire will result in a lasting erection. Viagra will not treat the underlying physical cause of your erectile dysfunction.
In Practice
What Happens When You Take Viagra?
Muscle tissue in the penis relaxes
Viagra causes a type of muscle tissue in the penis to relax, opening up the blood vessels in the penis, allowing it to fill with blood (the penis filling with blood is what causes an erection).
It takes 30 to 60 minutes
As long as you feel sexual desire, and have enough sexual stimulation, you may get an erection in as little as 12 minutes, although it most often takes from 30 to 60 minutes. It can take longer though, so don’t panic if it does.
It clears in five to six hours
On average, Viagra stays in your system for five to six hours. This varies though, and it depends on how much you take and how your body reacts to the meds.

DO NOT take Viagra if you are taking: other erectile dysfunction treatments, including any pills or creams or ointments; any treatments for pulmonary arterial hypertension (PAH) containing Sildenafil or other PDE5 inhibitors; nitrate medicines, often prescribed for chest pain; guanylate cyclase stimulators like Adempas (riociguat), prescribed for hypertension; medicines called alpha-blockers; medicines called HIV protease inhibitors; medicines to treat high blood pressure.
Other Medications

Lifestyle
Getting the Most From Viagra
There may be occasions when Viagra won’t work for you. If you have eaten a heavy meal or drank a large amount of alcohol before taking Viagra, you might find that it doesn’t work.
- 01
Alcohol
You can take Viagra with alcohol and a moderate amount should not impact the effectiveness of the medication. However drinking excessive amounts of alcohol can cause erectile dysfunction and can stop Viagra from working.
- 02
Driving and Machines
Viagra can cause side effects which can impair your ability to drive and use machinery, such as dizziness and vision problems. If you experience these side effects, you shouldn’t drive or use any machinery.
- 03
Your First Time
We understand that it can sometimes be a little bit nerve-wracking or stressful when trying Viagra for the first time. Unfortunately, this can impact the effectiveness of the treatment. Try not to put too much pressure on yourself, and remember to relax and enjoy the experience with your partner.
- 04
Storage and Expiry
Keep your Viagra in its original packaging to avoid any moisture getting to the tablets. Also make sure you store your meds in a cool, dry place and keep them below a temperature of 30°C. Wherever you store your ED meds, always keep them out of sight and reach of children.
Ongoing Care
Your 6 Month Check-Up
Make sure you book in with your GP for a check-up after you’ve been taking Viagra for six months. Even if it’s working and you feel healthy, it’s important not to miss this appointment.
ED may be an early sign of something much more serious, including heart problems, high cholesterol, high blood pressure, and diabetes. It’s important to rule these conditions out.
If Viagra Isn’t Working
If you feel that Viagra is not working for you please contact our doctors. They can consult with you and determine whether to change your dosage or try an alternative ED treatment. You shouldn’t try and change your dose yourself, and never take more than one Viagra tablet in 24 hours as this can increase the risk of serious side effects.
