1. WHAT CIMETIDINE TABLETS ARE AND WHAT THEY ARE USED FOR
The name of your medicine is Cimetidine Tablets 200mg, 400mg or 800mg (referred to as Cimetidine Tablets throughout this leaflet).
Cimetidine Tablets belong to a group of medicines called H2-receptor antagonists which act to decrease the natural production of acid in the stomach.
Cimetidine Tablets have been prescribed to treat any of the following:
• Ulcers in the stomach (gastric ulcer) or in the upper part of the intestine (duodenum ulcer);
• Recurrent and stomal ulceration;
• Ulcers in the stomach or duodenum which may be caused by non-steroidal antiinflammatory drugs (NSAIDs, often used to reduce pain, fever and inflammation);
• Acid from the stomach escaping into the food pipe causing pain, inflammation and heartburn (oesophageal reflux disease);
• Excess acid in the stomach caused by a tumor in the pancreas (Zollinger-Elison syndrome);
• Various conditions where reduction of gastric acid by cimetidine has been shown to be beneficial e.g.:
• indigestion symptoms (e.g.: stomach pain or discomfort , heartburn);
• meal-related upper abdominal pain;
• to prevent stress ulcers from bleeding;
• to be given before general anaesthesia to prevent damage to the lungs caused by breathing in stomach fluids (acid aspiration);
• to improve absorption of food and reduce fluid loss in short bowel syndrome;
• reduction of breakdown of pancreatic enzyme supplements;
2. BEFORE YOU TAKE CIMETIDINE TABLETS Do not take Cimetidine Tablets
- If you are hypersensitive (allergic) to cimetidine or any of the other ingredients of Cimetidine Tablets.
Take special care with Cimetidine Tablets
Consult your doctor before taking Cimetidine Tablets:
- If you suffer or have suffered in the past from kidney or liver disease.
- If you have a history of peptic ulcer, particularly if you are taking a non-steroidal antiinflammatory drug (NSAID) e.g.: aspirin, ibuprofen, naproxen, diclofenac.
- If you are taking drugs or you have an illness that could cause a fall in blood cell count.
- If you are middle aged or over, with new or recently changed indigestion symptoms (e.g.: stomach pain or discomfort, heartburn), other causes of your symptoms such as stomach cancer, should be excluded.
Pregnancy
Ask your doctor for advice before taking Cimetidine Tablets if you are pregnant or trying to become pregnant.
Breast-feeding
Ask your doctor for advice before taking Cimetidine Tablets if you are breast-feeding. Taking other medicines
Please inform your doctor or pharmacist if you are taking or have recently taken any other medicines, even those not prescribed.
In particular, tell your doctor if you are taking any of the following:
- Anticoagulants (to thin your blood) e.g. warfarin
- Anticonvulsants (to prevent fits) e.g. phenytoin
- Bronchodilators (for breathing difficulties) e.g. theophylline
- Anti-arrhythmics (to slow heart rate) e.g. lidocaine
- Immunodepressants (to prevent transplant rejection) e.g. ciclosporin
Cimetidine may worsen the fall in blood count which some medicines can cause. Check with your doctor or pharmacist if this applies to any medicines you may be taking.
3. HOW TO TAKE CIMETIDINE TABLETS
Always take Cimetidine Tablets exactly as your doctor has instructed you. You should check with your doctor or pharmacist if you are unsure.
The usual dosage is 400mg to 1600mg cimetidine per day, in divided doses. Do not take more than 2400mg cimetidine per day. If you suffer from kidney or liver problems, you may require a lower dose. The usual duration of treatment is 4-8 weeks.
Dosage and duration of treatment depend upon the symptoms treated, and their severity.
Read the label for the dosage your doctor has prescribed for you.
You may feel better after a few days, but you should keep taking your tablets until the prescribed course is finished. Your symptoms may come back if you stop your treatment too soon.
The tablets should be taken with meals and at bedtime and swallowed whole with a glass of water. Unless specifically directed by your physician, do not halve these film-coated tablets.
