Some Zantac side effects occur extremely infrequently in users of the medication. These should be reported immediately but are very likely never to occur. These side effects include vertigo, drowsiness, insomnia, muscle or joint pain, hair loss, pneumonia or blurred vision. Most of these side effects, such as hair loss, occurred in less than one percent of Zantac users.
