1. WHAT RANITIDINE INJECTION IS AND WHAT IT IS
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 the 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”.
2. WHAT YOU NEED TO KNOW BEFORE YOU HAVE

• triazolam for insomnia.
Midazolam may also be given before an operation.Tell your

Ranitidine 50mg/2ml Solution for Injection and Infusion
Please read this information carefully before giving Ranitidine
50mg/2ml Solution for Injection and Infusion (referred to as Ranitidine
Injection throughout this leaflet). Please refer to the Summary of
Product Characteristics for further details on this product.
Each 2ml ampoule of Ranitidine Injection contains 50mg of ranitidine as
ranitidine hydrochloride. Product provided in amber glass ampoules,
5 ampoules in a carton.
Solution for Injection and Infusion.
Clear, colourless solution.
Ranitidine Injection is indicated for the treatment of duodenal
ulcer, benign gastric ulcer, post-operative ulcer and of Zollinger Ellison Syndrome.
In the management of conditions where reduction of gastric secretion
and acid output is desirable, such as reflux oesophagitis.
As prophylaxis against:
• gastrointestinal haemorrhage from stress ulceration in seriously ill patients
• recurrent haemorrhage in patients with bleeding peptic ulcers
• acid aspiration (Mendelson's Syndrome) before anaesthesia in
patients at risk, particularly obstetric patients during labour.
Children (6 months to 18 years): Short term treatment of peptic ulcer.
Treatment of gastro-oesophageal reflux, including reflux oesophagitis
and symptomatic relief of gastro-oesophageal reflux disease.
Dosage and Method of Administration See SPC section 5.2
Pharmacokinetic Properties - Special Patient Populations.
Recommended rates of administration should not be exceeded as
bradycardia in association with rapid administration of ranitidine has
been reported rarely.
Adults (including elderly) and adolescents (12 years and older)
Ranitidine Injection may be given as:
• a slow (over two minutes) intravenous injection up to a maximum of 50
mg after dilution to a volume of 20 ml per 50 mg dose, which may be
repeated every 6 to 8 hours; or
• an intermittent intravenous infusion at a rate of 25 mg per hour for two
hours, the infusion may be repeated at 6 to 8 hours intervals; or
• as an intramuscular injection of 50 mg (2ml) every 6 to 8 hours.
In the prophylaxis of haemorrhage from stress ulceration in seriously ill
patients or the prophylaxis of recurrent haemorrhage in patients bleeding
from peptic ulceration, parenteral administration may be continued until
oral feeding commences. Patients considered to be still at risk may then
be treated orally with Ranitidine tablets 150 mg twice daily.
In the prophylaxis of upper gastro-intestinal haemorrhage from stress
ulceration in seriously ill patients a priming dose of 50 mg as a slow
intravenous injection followed by a continuous intravenous infusion of
0.125 - 0.250 mg/kg/hr may be preferred.
Prophylaxis of Mendelson's syndrome:
In patients considered to be at risk of developing acid aspiration, Ranitidine
Injection 50 mg may be given intramuscularly or by slow intravenous
injection 45 to 60 minutes before induction of general anaesthesia.
• 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
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

missed a dose, talk to your doctor or nurse.
If you have any further questions on the use of this product, ask
your doctor or nurse.
