1. What Zantac 75 Relief does

Zantac 75 Relief is used to treat indigestion and heartburn for up to 12 hours. The stomach produces acid which helps to digest food. Sometimes your stomach produces too much acid which can cause indigestion and heartburn.

The active ingredient is ranitidine hydrochloride which is a medicine called an 'H2-blocker’. It works by preventing your stomach from producing too much acid.

2. Check before taking Zantac 75 Relief

Do not take Zantac 75 Relief:

  • if you have ever had an allergic reaction to ranitidine or to any of the other ingredients (listed in Section 6)
  • if you are under 16 years.

Ask your doctor before you take this medicine:

  • if you have difficulty swallowing
  • if you have porphyria (too much pigment called porphyrin which may discolour the urine)
  • if you have unintended weight loss
  • if you are middle-aged or older with new or recently changed indigestion symptoms
  • if you have persistent stomach pain
  • if you have kidney or liver problems
  • if you are under regular medical supervision
  • if you have had a peptic ulcer
  • if you are elderly
  • if you have breathing problems
  • if you have a weak immune system
  • if you suffer from diabetes.

Talk to your doctor or pharmacist before taking Zantac 75 Relief if you are taking any other medicines, including those obtained without a prescription; particularly medicines to prevent blood clotting, such as warfarin, medicines for insomnia (e.g. triazolam, midazolam), medicines for lowering blood glucose (e.g. glipizide), medicines for fungal infections (e.g. ketoconazole, itraconazole, posaconazole), medicines for treating HIV infection (e.g. atazanavir, delavirdine), medicines for lung cancer (e.g. gefitnib) and non-steroidal anti-inflammatory painkillers (e.g. aspirin or ibuprofen). This advice is even more important if you are elderly.
