What Somac is used for
Somac is used to treat and help heal duodenal and gastric 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.
These can be caused in part by too much acid being made in the stomach.
Your doctor may also prescribe a course of antibiotics for you. Most people who have a peptic ulcer also have bacteria called Helicobacter pylori in their stomach. When Somac is taken with antibiotics, the combination therapy will kill the Helicobacter pylori and let your ulcer heal.
Somac can also be used to prevent ulcers in patients taking certain pain medicines called non-steroidal anti-inflammatory drugs.
Somac is also used to treat reflux oesophagitis or reflux disease. This can be caused by "washing back" (reflux) of food and acid from the stomach into the food pipe, also known as the oesophagus.
Reflux can cause a burning sensation in the chest rising up to the throat, also known as heartburn.
Somac is also used to prevent reflux oesophagitis from coming back.
Somac is used to treat a rare condition called Zollinger-Ellison syndrome, where the stomach produces very large amounts of acid, much more than in ulcers and reflux disease.
How Somac works
Somac belongs to a group of medicines called proton pump inhibitors (PPIs).
Somac works by decreasing the amount of acid the stomach makes, to give relief from the symptoms and allow healing to take place.
Your doctor may have prescribed Somac for another reason. Ask your doctor if you have any questions about why Somac has been prescribed for you.
There is no evidence that Somac is addictive.
This medicine is available only with a doctor's prescription.

Taking other medicines
Tell your doctor if you are taking any other medicines, including medicines that you buy without a prescription from your pharmacy, supermarket or health food shop.
Some medicines may be affected by Somac, or may affect how well it works. These may include drugs whose activity depends on the acidity of the stomach e.g. ketoconazole.
You may need different amounts of your medicine, or you may need to take different medicines. Your doctor will advise you.
How to take Somac
How much to take
Depending on your medical condition, the usual dose is one 20mg or one 40mg tablet each day. However, if your doctor also prescribes antibiotics with Somac, the dose of Somac is two 40mg tablets per day, morning and evening with or without food for 7 days.
The dose and frequency of Somac that your doctor prescribes for you depends on your medical condition. Your doctor may change the dose as your condition changes.
How and when to take it
Swallow your tablets whole with a little water with or without food.
If you are taking antibiotics in combination with Somac therapy, follow the instructions for the use of each drug carefully.
Do not crush or chew the tablets. Somac tablets have a special coating to protect them from the acidic contents of your stomach. For Somac to work effectively, this coating must not be broken.
How long to take it
Your doctor will tell you how long to take your 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 it as soon as you remember, and then go back to taking it as you would normally.
Do not take a double dose to make up for the dose that you missed.
If you have trouble remembering to take your medicine, ask your pharmacist for some hints.
If you take too much (overdose)
Immediately telephone your doctor or the National Poisons Information Centre (telephone 03 474 7000 ) for advice, if you think that you or anyone else may have taken too much Somac. Do this even if there are no signs of discomfort or poisoning.
