Is Zantac [ranitidine] considered an Antacid?
Zanatac (and the generic ranitidine) is a H2 Blocker. It blocks the action of histamine at the H2 receptor in the body, thereby reducing the amount stomach acid produced. Most people seem to tolerate it very well. Potential side effects nausea, headache, diarrhea and constipation. Long-term use has been associated with Vitamin B12 deficiency.
Zantac is not considered an antacid. It reduces production of stomach acid. Antacids are products that reduce stomach acid already in the stomach by neutralizing the acid on contact. Some popular antacids include Tums, Rolaids and Mylanta. Antacids work immediately, acid reducing agents like ranitidine work systemically to reduce the production of stomach acid. So, if you see directions or a label indicating it should be avoided with antacids, it typically is not referring to ranitidine.
If you find yourself having frequent heart burn and stomach acid issues, be sure to see a healthcare provider. Constant symptoms may be an indication of a more serious condition.
