Ranitidine is a gastrointestinal drug. It belongs to the group known as histamine H2 receptor blockers, which reduce the secretion of stomach acid.

For adults Ranitidine effervescent tablets are used for the treatment of diseases of the stomach and duodenum, in which a reduction of stomach acid is required:

•    Intestinal ulcers

•    Benign stomach ulcers

•    Prevention of the return of stomach ulcers in patients with recurrent ulcers

•    Inflammation of the gullet as a result of the backflow of stomach contents (reflux oesophagitis)

•    Zollinger-Ellison Syndrome (a disease whereby the stomach produces too much acid).

Ranitidine is not indicated for the treatment of mild stomach/intestinal complaints, such as nervous stomach.

For children (3 to 18 years) Ranitidine effervescent tablets are used for:

•    the short term treatment of stomach ulcers (ulcers in the part of the gut that connects to the duodenum)

•    the treatment of inflammation of the gullet (the tube between your mouth and stomach) caused by too much stomach acid. This can cause pain or discomfort sometimes known as "indigestion", "dyspepsia" or "heartburn'"


Do not take Ranitidine effervescent tablets:

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

Warnings and precautions

Talk to your doctor or pharmacist before taking Ranitidine effervescent tablets.

•    if you suffer from a reduced kidney function; a lower dose may be needed (see section 3: "How to take Ranitidine effervescent tablets")

•    if you have a history of porphyria (a severe illness whose symptoms include severe stomach pain, mental confusion and muscle weakness)

•    if you suffer from severe liver impairment; you should use this medicine with caution

•    if you are elderly, if you have a chronic lung disease, diabetes or problems with your immune system, you may have an increased risk of developing community acquired pneumonia

•    if you have mild, short-lasting stomach or intestinal complaints; ranitidine is indicated for patients with severe complaints and should not be used to treat mild complaints.

Stomach and duodenal ulcers can be caused by a certain bacteria called Helicobacter pylori. Your doctor may therefore prescribe other medicines (antibiotics) that can kill these bacteria.

Before starting treatment with ranitidine, it is important that your doctor has established that your stomach/ duodenal ulcer is not malignant.

Ask your doctor if any of the above warnings apply to you, or has ever applied to you in the past.

Other medicines and Ranitidine effervescent tablets

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.

An interaction may occur if you take these effervescent tablets at the same time as:

•    coumarin anticoagulants (e.g. warfarin, for thinning your blood)

•    procainamide and N-acetylprocainamide (medicines for the treatment of cardiac arrhythmias)

•    triazolam, midazolam (mood-enhancing drugs)

•    glipizide (medicine for the treatment of diabetes)

•    ketoconazole (medicine for the treatment of fungal infections)

•    atazanavir, delaviridine (medicine for treatment of HIV infection)

•    gefitinib (medicine for treatment of lung cancer).

You should always take medicines which reduce stomach acid (e.g. antacids, sucralfate) 2 hours after Ranitidine effervescent tablets, in order to prevent a reduction in the efficacy of Ranitidine effervescent tablets.

Ranitidine effervescent tablets with food, drink and alcohol

This medicine can be used with or without a meal. Ranitidine can increase the effect of alcohol.

Pregnancy and breast-feeding

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

If you are pregnant, might become pregnant or are breast-feeding, you should not take this medicine unless your doctor advises it is essential.

Ranitidine passes into breast milk.

Breast-feeding is therefore not recommended whilst using Ranitidine.

Driving and using machines

No effects on the ability to drive or operate machinery were reported when using Ranitidine effervescent tablets only. Ranitidine effervescent tablets can increase the effect of a small amount of alcohol. If you have drunk alcohol, do not drive and/or use machines that require you to be alert.

If you have been told by your doctor that you have an intolerance to some sugars (e.g. lactose), contact your doctor before taking this medicine.

Ranitidine effervescent tablets contains sodium

Each Ranitidine 150 mg effervescent tablet contains 120 mg of sodium, the 300 mg effervescent tablet contains 240 mg of sodium. You should bear this in mind if you are on a low-sodium or sodium-free diet.


Always take this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure.
