Ranitidine Injection is a solution for injection or infusion into a vein, or injection into a muscle. It contains ranitidine as the active substance.

Ranitidine is one of a group of medicines called H2-antagonists that lowers the amount of acid in your stomach.

It is used in adults (including the elderly) to:

  • Heal and stop ulcers of the stomach or duodenum (the stomach empties into this part of the intestine)
  • Improve problems caused by acid in the food pipe (oesophagus) or too much acid in the stomach. Both of these can cause pain or discomfort sometimes known as ‘indigestion’, ‘dyspepsia’ or ‘heartburn’
  • Stop ulcers from bleeding
  • Stop acid coming up from the stomach while under anaesthetic during an operation.

It is used in children (6 months to 18 years) to:

  • Heal ulcers in the stomach, or part of the gut that it empties into (the duodenum)
  • Heal and stop problems caused by acid in the food pipe (oesophagus) or too much acid in the stomach. Both of these can cause pain or discomfort sometimes known as “indigestion”, “dyspepsia” or “heartburn”.

  • if you are allergic to ranitidine or to any of the other ingredients in this medicine (listed in Section 6).

If you are not sure talk to your doctor or pharmacist before having Ranitidine Injection.

Warnings and precautions

  • If you have had stomach ulcers before
  • If you are over 65 years old
  • If you have lung disease

If you are not sure if any of the above applies to you, talk to your doctor or pharmacist before having this medicine.

Other medicines and Ranitidine Injection

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, including medicines that you buy without a prescription and herbal medicines. This is because ranitidine can affect the way some other medicines work. Also some other medicines can affect the way ranitidine works.

In particular tell your doctor or pharmacist if you are taking any of the following medicines:

  • lidocaine, a local anaesthetic
  • anticoagulants (such as warfarin), used to thin the blood
  • propranolol, procainamide or n-acetylprocainamide, for heart problems
  • diazepam, for worry or anxiety problems
  • phenytoin, for epilepsy
  • theophylline, for breathing problems (asthma)
  • glipizide, for lowering blood glucose
  • atazanavir or delaviridine, for treating HIV infection
  • gefitnib for lung cancer
  • ketoconazole for fungal infections or thrush
  • triazolam for insomnia.

Midazolam may also be given before an operation. Tell your doctor you are taking ranitidine before you have an operation in case he or she wants to give you midazolam.

If you are taking erlotinib, a drug used for the treatment of certain types of cancer, talk to your doctor before you take Ranitidine Injection. Ranitidine contained in Ranitidine Injection may decrease the amount of erlotinib in your blood and your doctor may need to adjust your treatment if it is used while you are receiving erlotinib.

If you are not sure if any of the above applies to you, talk to your doctor, pharmacist or nurse before having Ranitidine Injection.

You will never be expected to give yourself this medicine. It will always be given to you by someone who is trained to do so.

Your doctor will decide the correct dose of Ranitidine Injection for you.

Adults (including the elderly) and adolescents (12 years and older): This can be given by the doctor or nurse in one of three ways:

  • As a single injection into a muscle
  • As a slow infusion into a vein. This is where the drug is slowly given to you over a few minutes
  • As a continuous infusion into a vein. This is where the drug is slowly given to you over a few hours.

The recommended dose for an adult (including the elderly) and adolescents (12 years and older) is 50 mg every 6 to 8 hours, as a single injection into a muscle.

Different doses may also be given to you as a slow infusion or continuous infusion, depending on what condition you are being treated for.

Children and infants (6 months to 11 years): The dose will be given by a slow injection into a vein. The maximum dose is 50mg every 6 or 8 hours. It is usually only given if your child is unable to take ranitidine by mouth.

Kidney disease: If your kidneys are not working properly your doctor may give you a lower dose.

Your doctor or nurse will give you Ranitidine Injection so it is unlikely that you will receive too much.
