It probably depends on how strong the side effects of your meds are. I've had meds that made me dizzy, and I sure as hell didn't drive under those meds. Other meds made me throw up fairly frequently; can you picture yourself suddenly hurling all over your windshield, or onto the person in the driver's seat?

Only you know what kind of side effects you have, and how strong they are. As for your SZA, what symptoms do you experience? I have an imaginary girlfriend who sometimes finds it quite funny to get me to not look both ways when crossing against the traffic light. Almost been hit, several times now. If you have symptoms like that, my answer would be, "hell no, don't drive while SZA."
