Can Zantac (ranitidine) 150mg cause depression? Took yesterday morning and feeling mentally, foggy, dull, tired, and excessive crying over smallest things.

Reported but rare. Depression has been occasionally reported with Zantac (ranitidine) but usually after taking for several days and more likely in "severely ill elderly patients." So if this was a reaction it is unusual; I wonder if you reacted to the fillers or binders instead of the medicine. This may just be a coincidence but the only way to find out would be to try it again... See http://tinyurl.com/j6dgq5u for more...
