You : You are correct - the maximum dose of Zantac (ranitidine) is 300mg or 2 tablets. That being said, accidentally taking an extra one once should not be dangerous. If you have any specific concerns you can always call the poison control center toll free at 1-800- 222-1222.

No harm: Agree with Dr. M, Taking one extra Zantac will not do any harm. Have a healthy diet, exercise, drink plenty of water, have safe sex, if you do, and get HPV vaccine. Wish you good health!
