What Pamacid is used for

Pamacid is used in the treatment of the following conditions:
Reflux disease
Also called reflux oesophagitis, this condition is caused by the washing back of food and acid from the stomach into the food pipe. A painful burning sensation occurs in the chest rising up to the throat (heartburn) and most often occurs after eating or at night.
Peptic ulcers
These ulcers usually cause pain and discomfort (indigestion) which is felt between the navel and the breast bone. Depending on the position of the ulcer it is called a gastric or duodenal ulcer. A gastric ulcer occurs in the stomach and a duodenal ulcer in the duodenum, which is the tube leading out of the stomach.
Pamacid is also used to help prevent the re-occurrence of duodenal ulcers and reflux disease.
Zollinger-Ellison syndrome
A rare condition where the stomach produces excessive amounts of acid, much more than in peptic ulcers and reflux disease.
Pamacid belongs to a group of medicines called histamine H2 antagonists or histamine H2 blockers. These medicines work by decreasing the amount of stomach acid produced, which in turn helps reduce the pain and also allows the ulcer and/or reflux disease to heal in most people.
Ask your doctor if you have any questions about why Pamacid has been prescribed for you.
Your doctor may have prescribed Pamacid for another reason.
Pamacid is not recommended for use in children, as the safety and effectiveness of Pamacid in children have not been established.
There is no evidence that Pamacid is addictive.

Peptic ulcers
The usual dosage for the treatment of peptic ulcers is one 40 mg tablet at night.
To help stop duodenal ulcers from coming back the usual dosage is one 20 mg tablet taken at night.
Reflux disease
The usual dosage for the treatment and maintenance of reflux disease is one 20 mg tablet taken twice a day.
Zollinger-Ellison syndrome
The dose depends on how much acid your stomach makes. Your doctor will decide how much you need to take.
People with kidney problems may require lower doses.

When to take it

Swallow the tablets with a glass of water.
Pamacid can be taken with or without food.
If you are taking one dose a day, take the tablet at night.
If you are taking two doses a day, take one tablet in the morning and one at night.
Take your tablets at about the same time each day.
This will help you remember when to take the tablets.

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 the missed dose as soon as you remember, and then go back to taking your tablets as you would normally.
Do not take a double dose to make up for the dose you missed.
If you are not sure what to do, ask your doctor or pharmacist.

Do not stop taking Pamacid, even if you feel better after a few days, unless advised by your doctor.
The ulcer may come back if you stop treatment too early.
For treatment of reflux disease and Zollinger-Ellison syndrome you usually need to take Pamacid for longer. Your doctor will let you know how long to keep taking the tablets.
Keep taking Pamacid for as long as your doctor recommends.

If you take too much (overdose)

Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) for advice, or go to the nearest hospital, if you think you or anyone else may have taken too much Pamacid. Do this even if there are no signs of discomfort or poisoning.
