I am taking primidone for benign essential tremor, pristiq for depression, and cetirizine for vasomotor rhinitis. I like a glass of red wine with my evening meal, but find that it started to make me very unsteady on my feet. I stop taking the cetirizine and I am back to normal after the red wine, but I still need something to stop my nose from running all the time.
Which antihistamine will have the least negative reaction with the drugs Primidone & Pristiq?
