Sildenafil Side Effects – What They Don’t Tell You

Sildenafil has become a popular drug in the treatment of Erectile Dysfunction. With an effective delivery system and efficient pharmacology, the drug has results and is able to address the issues of millions of men around the world affected by ED. However, many of these people are using Sildenafil without being aware of the side effects of Sildenafil.

Sildenafil has side effects just like any other pharmaceutical drug and going beyond the recommended dosage, or taking a dosage that is not compatible with your lifestyle and existing medical conditions, if any, could result in a compromised situation. 

This article will examine the different side effects of Sildenafil and the impacts they can have if one chooses to exceed the recommended dosage or not follow the advice of a doctor when it becomes necessary. We hope this added awareness on Sildenafil will help you in your fight against ED.


The most commonly reported side effect of Sildenafil is headaches. This is expected, especially if you understand the mechanics of the drug. Sildenafil is a PDE5 inhibitor; PDE5 is an enzyme which, when inhibited, causes the blood flow to increase. This obviously will have an effect on the body’s overall blood pressure and could lead to a headache. 

The best way to deal with this is to keep yourself hydrated and make adjustments for a healthier lifestyle. If the problem persists, you can try reducing the dosage even lower than the recommended dosage. Failing that, you should consult with a doctor.

Because of this effect of Sildenafil on blood flow, people with pre-existing heart conditions are advised to speak to their doctor before they decide to start taking Sildenafil.


The change in blood flow and blood pressure can also sometimes lead to slight dizziness and flushing. Again, drinking lots of water and reducing the dosage helps significantly. However, if the problem persists then you need to consider seeing your doctor.


Although infrequent, some have complained about stomach issues, like diarrhoea and cramps, when taking Sildenafil. This usually happens if you’ve taken Sildenafil around meal time and could be addressed by timing your meals accordingly. Avoid a heavy or full stomach if you’re taking Sildenafil and, if possible, wait for at least an hour-and-a-half before taking a pill.


While there have been a few rare cases of this happening, some have stated that they experienced problems in vision by taking Sildenafil. If you experience such an issue, you should immediately discontinue the drug and consult with your doctor immediately.


If you have a pre-existing heart condition and are on medication for it, then you NEED to consult with a doctor before you take Sildenafil. Sildenafil citrate, the main active compound in Sildenafil, reacts with nitrates, used in heart medication, in a very volatile manner. You can end up with several further health complications if something serious were to happen.


We hope the above has added to your knowledge on Sildenafil and makes it easier for you to manage dealing with ED. Click here if you’d like to learn more about Sildenafil.
