Both Zantac syrup and tablets are taken one to four times a day, depending on the particular product and condition being treated.
While most people tolerate Zantac well, side effects are possible. Some of the most common side effects that have been reported with this drug include nausea or vomiting, headaches, diarrhea, and constipation.
