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.
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 may also be used to prevent ulcers associated with the use of non-steroidal anti-inflammatory drugs (NSAIDs). These are medicines used to relieve pain, swelling and other symptoms of inflammation, including arthritis (inflammation of the joints).
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 also 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.
This medicine belongs to a group of medicines called proton pump inhibitors (PPIs).
This medicine works by decreasing the amount of acid the stomach makes, to give relief from the symptoms and allow healing to take place.
Ask your doctor if you have any questions about why it has been prescribed for you. Your doctor may have prescribed it for another purpose.
This medicine is not addictive. This medicine is available only with a doctor’s prescription.
This medicine is not expected to affect your ability to drive a car or operate machinery.
However, do not drive a car or operate machines if you experience side effects such as dizziness or blurred vision.
Somac should not be given to children under 5 years of age. There is not enough information to recommend the use of this medicine for children under the age of 5 years.

How to take Somac
Follow all directions given to you by your doctor or pharmacist carefully. They may differ from the information contained in this leaflet.
If you do not understand the instructions on the box/bottle, ask your doctor or pharmacist for help.
How much to take
The usual dose is 40 mg per day.
However, if your doctor also prescribes antibiotics in combination with Somac for the treatment of duodenal ulcers, the dose of Somac is 80 mg per day. The first 40 mg dose should be taken in the morning and the second should be taken before the evening meal for 7 days.
Your doctor will prescribe the dose that is right for you.
In children over 5 years of age, the dose of Somac for reflux oesophagitis or reflux disease is based on weight and may be 20 mg or 40 mg, depending on the condition being treated. Somac should not be taken for longer than 8 weeks.
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 to take it
Swallow your tablets whole with a little water with or without food.
If you are using Somac granules, take it half an hour before a meal without chewing or crushing the granules. Take the granules in apple juice, orange juice or water as follows:
- open sachet
- sprinkle intact granules into a small volume of apple juice, pulp-free orange juice, or water (at least 15 mL). Alternatively, a tablespoon may be used
- mix briefly just bef
- drink straight away
- to ensure that you have taken all the medicine, rinse the container thoroughly once or twice with apple juice, orange juice or water to remove any remaining granules and drink immediately
You can also take the granules in applesauce as follows:
- open sachet
- sprinkle intact granules on a teaspoon of applesauce.
- swallow within 10 minutes of preparation
Somac granules are intended for people who have difficulty swallowing tablets including those who require a nasogastric tube.
When to take it
Take Somac at about the same time each day. Taking it at the same time each day will have the best effect. It will also help you remember when to take it.
If you are taking other medicines, like antibiotics, in combination with Somac therapy, follow the instructions for the use of each medicine carefully.
Do not crush or chew the tablets or granules. Somac tablets and granules 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
Continue taking your medicine for as long as your doctor or pharmacist tells you.
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. This may increase the chance of getting an unwanted side effect.
If you are not sure what to do, ask your doctor or pharmacist.
If you have trouble remembering when to take your medicine, ask your pharmacist for hints.
If you take too much (overdose)
Immediately telephone your doctor or Poisons Information Centre (telephone Australia 13 11 26 or New Zealand 0800 764 766), or go to Accident and Emergency at your nearest hospital, if you or anyone else may have taken too much Somac.
