QA Question: 

ZANTAC75® is an acid reduction product which contains the effective non-prescription strength of ranitidine (75 mg), a commonly used acid reliever.

ZANTAC® tablets provide fast and effective relief of the burning and discomfort of heartburn, acid indigestion, upset stomach and sour stomach associated with excess acid. ZANTAC® tablets reduce and control stomach acid for up to 12 HOURS, day or night.

ZANTAC® tablets can also effectively prevent symptoms of heartburn and acid indigestion when taken 30 to 60 minutes before eating food and/or drinking beverages that cause heartburn.

ZANTAC® tablets work by reducing the production of excess stomach acid, which causes the burning and discomfort of heartburn and acid indigestion. This is what makes ZANTAC® different from antacids which only neutralise the acid in your stomach. Antacids do not reduce the production of excess stomach acid.

ZANTAC® tablets provide fast relief, treatment and prevention, day or night, of the following symptoms:

  • Heartburn
  • Acid Indigestion
  • Upset or Sour Stomach
  • ZANTAC® tablets
  • have stomach or duodenal ulcers
  • are taking prescription medicines for stomach ulcers
  • are taking medications such as antacids, ketoconazole, sucralfate, procainamide, or any other prescription drugs
  • have difficulty or pain on, experience choking, swallowing or continuous stomach pain or discomfort
  • are nauseous, vomiting blood, or have bloody or black stools
  • have heartburn that is frequent (> 3 times per week) and/or unusually severe
  • have had heartburn for over 3 months
  • have chest pain
  • are taking non-steroidal anti-inflammatory drugs (NSAIDs),(because these medicines may be causing your symptoms)
  • are pregnant, or breast-feeding
  • have kidney disease
  • suffer from porphyria (a rare blood disorder)
  • experience unintended weight loss
  • are over 40 years of age and are experiencing new or recently changed symptoms of heartburn or acid indigestion
  • have any other illness, or are taking any prescription medicines, for which you are seeing a doctor regularly
  • are under 16 years of age

For relief of symptoms: Adults and children 16 years and older: Take one tablet swallowed whole with a glass of water when symptoms appear, day or night. If symptoms persist for more than 1 hour or return after 1 hour, a second tablet may be taken. The maximum dosage is 2 tablets (150 mg ranitidine) in a 24 hour period.

For prevention of symptoms brought on by consuming food or beverages, 1 tablet should be taken 30 to 60 minutes before eating a meal or consuming beverages expected to cause symptoms. Consult your doctor if symptoms get worse or continue after 14 days of treatment. ZANTAC® and antacids should be taken one hour apart.
