Brief Answer:
No adverse interaction between the main ingredients

Detailed Answer:
Hello,
The main ingredient of Vydox is L Arginine which has no adverse interaction with Viagra. The other ingredients are herbal. The combination of Ginkgo biloba and Ginseng can increase the bleeding tendancy if you are on aspirin or any medicine that interferes with the clotting mechanism.
As a couple of the herbs used are not well researched , it is not possible to give an opinion regarding them. It may be a good idea to ask the manufacturer of Vydox whether they are aware of any interaction.
Take care
