What NIZAC is used for
The name of your medicine is NIZAC. It contains the active ingredient called nizatidine.
NIZAC belongs to a class of medicines called H2– antagonists or H2– blockers. NIZAC works by reducing the amount of acid in your stomach. This helps reduce the pain and allows the ulcer and reflux disease to heal in most people.
NIZAC is used to treat the following conditions:
- Reflux oesophagitis or reflux disease. This can be caused by “washing back” (reflux) of food and acid from the stomach into the food pipe. Reflux can cause a burning sensation in the chest rising up to the throat, also known as heartburn.
- Ulcers. NIZAC is used to treat peptic ulcers. Depending on the position of the ulcer it is called a gastric or duodenal ulcer. A gastric ulcer occurs in the stomach. A duodenal ulcer occurs in the duodenum which is the tube leading out of the stomach. Ulcers can be caused in part by too much acid being made in the stomach.
- NIZAC is also used to stop duodenal ulcers from coming back.
Your doctor may have prescribed NIZAC for another reason. Ask your doctor or pharmacist if you have any questions about why NIZAC has been prescribed for you.
There is no evidence that NIZAC is addictive.
Before taking NIZAC
You should tell your doctor if you have any of the following conditions or if you have ever experienced any of these conditions. It is very important that your doctor is aware of these matters when determining whether or not to prescribe NIZAC.

Do NOT take NIZAC
- if you have had an allergic reaction to NIZAC, other histamine H2-receptor antagonists (eg. cimetidine, ranitidine, famotidine) or to any of the ingredients listed at the end of this leaflet (see ‘Product Description’). Signs of an allergic reaction include itching of the skin, shortness of breath, faintness and hayfever.
- if the packaging is torn or shows signs of tampering.
- if the expiry date on the pack has passed. If you take this medicine after the expiry date has passed it may not work as well.

- if you are pregnant or intend to become pregnant.
- if you are breast-feeding or plan to breast-feed.
- if you have kidney or liver disease.

Tell your doctor about these things before you take NIZAC.
How to take NIZAC
How much to take
Your doctor will tell you how much NIZAC you need to take each day depending on your condition.
When to take it
The 150 mg capsule is usually taken in the morning and in the evening before you go to bed. The 300 mg capsule is usually taken once daily, at bedtime.
How to take it
Both the 150 mg and 300 mg capsules should be swallowed whole with a glass of water or another liquid.
How long do I take it
Your doctor will tell you how long you should continue taking NIZAC capsules. Do not stop taking the capsules just because you feel better. If you stop taking your capsules too early then your condition will not have been properly treated.
If you forget to take it
If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to. Otherwise, take it as soon as you remember, and then go back to taking NIZAC as you would normally.

Do not take a double dose to make up for the dose that you missed.
If you take too much
Immediately telephone your doctor or Poisons Information Centre (13 11 26), or go to casualty at your nearest hospital, if you think you or anyone else has taken too much NIZAC. Do this even if there are no signs of discomfort or poisoning. You made need urgent medical attention.

Things you must NOT do
Do not give NIZAC to anyone else. Your doctor has prescribed it for you and your condition.
Do not take NIZAC to treat any other complaints unless your doctor tells you to.
Things to be careful of
Be careful driving or operating machinery until you know how NIZAC affects you. NIZAC may cause dizziness or lightheadedness in some people. Make sure you know how you react to NIZAC before you drive a car or operate any machinery.
Your doctor may advise you to limit your alcohol intake while you are being treated for your condition.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking NIZAC.

Ask your doctor or pharmacist to answer any questions you may have.
While you are taking NIZAC
Tell your doctor if you notice any of the following common side effects and they worry you
- itchy skin
Incidences of abnormal liver function, accompanied by jaundice (yellow skin) have been rarely reported by patients taking NIZAC. This side effect has been reversed when NIZAC is stopped.
