1. What is Cimetidine Oral Solution and what is it used for

The name of your medicine is Cimetidine 200mg/5ml Oral Solution. It contains cimetidine. This belongs to a group of medicines called H2 antagonists, which reduce the amount of acid in your stomach.

This medicine is used to:

  • heal and stop ulcers in the stomach, or the part it empties into, the duodenum
  • heal and stop problems caused by acid in the gullet (oesophagus) or too much acid in the stomach. This can cause pain or discomfort known as indigestion or heartburn
  • prevent ulcers from bleeding
  • prevent ulcers which may be caused by medicines called non-steroidal anti-inflammatories (NSAIDs), often used to treat arthritis
  • improve absorption of food and reduce fluid loss in short bowel syndrome
  • be given before an operation to prevent acid coming up from the stomach whilst under anaesthetic.

2. Before you take Cimetidine Oral Solution

Do not take Cimetidine Oral Solution and tell your doctor if:

  • you are allergic (hypersensitive) to cimetidine or any other ingredients in this liquid (listed in Section 6 below)
    The signs of an allergic reaction include a rash, itching or shortness of breath
  • you are pregnant, likely to become pregnant and if you are breast-feeding.

Do not take this medicine if any of the above apply to you. If you are not sure, talk to your doctor or pharmacist before taking cimetidine.

Take special care with Cimetidine Oral Solution

Before you take cimetidine, tell your doctor if:

  • you have kidney problems
  • you have lost weight recently and also have stomach ache, stomach pain or indigestion at the same time, particularly if you are over 40.

You should see your doctor regularly especially if you are taking Cimetidine Oral Solution as well as medicine for arthritis. This is particularly important in the elderly or those with a history of ulcers.

If you are not sure if any of the above apply to you, talk to your doctor or pharmacist before taking cimetidine.
