I'm Epileptic. Can Pseudovent 400 cause seizures?

I have had a viral infection for the past week. I also take medications for my seizures such as Lamictal and Zonegran twice daily, to control them. Cold medications over the counter I cannot take such as Sudafed I cannot take because they can cause seizures, so my doctors calls in a perscription drug. This Is this the first time I took the Pseudovent 400, and last night when I went out to eat with my family I had 3 small seizures in a row. I have taken this cold/sinus medicine for a week. I'm better now, but I do question can this drug possibly could bring on a seizure.

Thank You
