Side effects may vary.

I just realized I never posted these illustrations I did a few months ago on some of the possible side effects of Viagra.

Since it was originally being designed as a blood pressure medication and its common use was really just a side effect of that, Viagra can give you a fatal decrease of blood pressure in your heart.

By far one of the most odd and kinda flat out scary side effects is that the blood pressure effects can actually decrease blood pressure in the capillaries of the eyes, specifically the ones that control the red rods and making everything look blue. The same effect can also potentially blind you.
