What is in this leaflet
This leaflet answers some common questions about Tacidine.
It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.
All medicines have benefits and risks. Your doctor has weighed the risks of you taking Tacidine against the benefits they expect it will have for you.
If you have any concerns about taking this medicine, talk to your doctor or pharmacist.
Keep this leaflet with your medicine. You may need to read it again.
What Tacidine is used for
Tacidine is used to treat both gastric ulcers and duodenal ulcers. A gastric ulcer occurs in the stomach. A duodenal ulcer occurs in the duodenum (which is a tube leading out of the stomach). The ulcers can be caused in part by too much acid being made in the stomach.
Tacidine is also used to help stop duodenal ulcers from coming back.
Tacidine is also used to treat reflux oesophagitis or reflux disease. This is caused by "washing back" (reflux) of food and acid from the stomach into the food pipe (also known as the oesophagus).
Reflux causes burning sensation in the chest rising up to the throat (heartburn) and most often occurs after eating or at night.
Tacidine belongs to a group of medicines called histamine H2 antagonist or histamine H2 blockers. These medicines work by reducing the amount of stomach acid produced which in turn reduces the pain and allows the ulcers and/or reflux disease to heal in most people.
Ask your doctor if you have any questions about why Tacidine has been prescribed for you. Your doctor may have prescribed Tacidine for another reason.
Tacidine is not recommended for use in children, as the safety and effectiveness of Tacidine in children have not been established.
This medicine is not addictive.
This medicine is available only with a doctor's prescription.

How to take Tacidine
Follow all directions given to you by your doctor and pharmacist carefully. They may differ from the information contained in this leaflet.
If you do not understand the instructions on the pack, ask your doctor or pharmacist.
How much to take
The dose varies from person to person:
- duodenal and stomach ulcers – the recommended daily dosage is 150 mg twice daily or 300 mg once in the evening
- to stop duodenal ulcers from coming back – the usual dosage is 150 mg once daily
- reflux disease – the recommended dosage is 150 mg twice daily.
Elderly people and those who have kidney problems may need lower doses.
How to take it
Swallow the capsules whole with a full glass of water.
When to take it
Take Tacidine at about the same time each day. This will allow Tacidine to have its best effect and also help you remember when to take it.
Tacidine can be taken with or without food.
The 150 mg capsule is usually taken twice a day – one capsule in the morning and one capsule in the evening before you go to bed.
The 300 mg capsule is usually taken once daily at bedtime.
How long to take it
Continue taking Tacidine for as long as your doctor tells you.
Do not stop taking Tacidine, even if you feel better after a few days, unless advised by your doctor. If you stop taking your medicine 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 your medicine as you would normally.
Do not take a double dose to make up for the dose you missed. This may increase the chance of you getting an unwanted side effect.
If you are not sure what to do, ask your doctor or pharmacist.
If you take too much (overdose)
Immediately telephone your doctor, or the Poisons Information Centre (telephone 13 11 26), or go to Accident and Emergency at the nearest hospital, if you think you or anyone else may have taken too much Tacidine. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
