What CARBAGLU is used for

Carbaglu is used to eliminate excessive levels of ammonia, referred to as hyperammonaemia. The high levels of ammonia in the blood may be caused by the lack of a specific liver enzyme called N-acetyl glutamate synthase (NAGS) or due to isovaleric acidaemia, methylmalonic acidaemia or propionic acidaemia.

High levels of ammonia in the blood are toxic for the brain and leads in severe cases, to reduced levels of consciousness and coma.

Some people are born with inherited diseases that cause some of the body’s enzymes to be missing or defective. The deficiency of NAGS is a rare disorder and results in patients not being able to eliminate nitrogen waste from the body which builds up after eating protein. This disorder persists for life and therefore the need for this treatment is lifelong.

Isovaleric acidaemia, methylmalonic acidaemia and propionic acidaemias are rare disorders that can inhibit NAGS and cause episodes of hyperammonaemia. The treatment of elevated ammonia in these disorders is required during these episodes.

Carbaglu helps the body’s natural process to eliminate ammonia by triggering the enzymes required to convert this to urea. This is eliminated from the body in urine.

Ask your doctor if you have any questions about why Carbaglu has been prescribed for you.

This medicine is available only with a doctor’s prescription.

Before your doctor gives you CARBAGLU

Tell your doctor if you:

  • Have allergies to any medicines
  • Are taking or using any other medicines. These include medicines bought from pharmacies, supermarkets and health food stores
  • Have any other medical conditions
  • Are pregnant or breast feeding.

If you want further information, consult your doctor.

How to take CARBAGLU

Follow all directions given to you by your doctor and pharmacist carefully. These directions may differ from the information contained in this leaflet.

Your doctor may discuss with you the need to be on a restricted diet while you take Carbaglu.

If you do not understand the instructions, ask your doctor or pharmacist for help.

Your doctor will evaluate your individual responsiveness to Carbaglu before initiating any long term treatment.

The dose will be individually adjusted in order to maintain normal ammonia plasma levels.

Once the bottle containing the Carbaglu tablets has been opened, the tablets can be used for 3 months. Write the date when the bottle was first opened in the space provided on the bottle label.

How much to take

Each tablet contains 200mg.

The normal initial dose of Carbaglu is 100mg per kilogram of body weight per day. This dose maybe increased to 250 mg per kilogram of body weight per day.

For patients suffering from NAGS deficiency, in the long term, the daily dose usually ranges from 10 mg to 100 mg per kilogram of body weight. The total daily dose should be divided into 2 to 4 doses and round to the nearest 100 mg (half a Carbaglu tablet).

Your doctor may also recommend other therapies to help lower your ammonia levels.

Always consult your doctor with questions about your prescribed dose.

How to take it

Carbaglu tablets should not be swallowed whole or crushed.


Each 200 mg tablet should be dispersed in 5 to 10 ml of water and taken immediately.

Carbaglu tablets do not dissolve completely in water and undissolved particles of the tablet may remain in the mixing container. To ensure complete delivery of the dose, rinse the mixing container with additional volumes of water and swallow the contents immediately.

The suspension may taste slightly acidic.


Each 200 mg tablet should be dispersed in a minimum of 2.5 ml of water. For swallowing using a syringe, draw up the volume of the liquid using an oral syringe and administer immediately. The syringe may be refilled with a small amount of water (1 – 2 mL) and administered.

For use with a nasogastric tube, the dose is given in the same way as above, with the tube flushed with water after administration.

When to take it

Carbaglu treatment should be initiated under the supervision of a doctor and given before meals or feeding.

How long to take it

Take Carbaglu for as long as your doctor tells you.

Carbaglu helps to lower your levels of ammonia in the blood, but it does not cure your condition.

If you forget to take it

Do not take a double dose to make up for the dose that you missed. This may increase the chance of you getting an unwanted side effect.

If you are not sure what to do, talk to your doctor or pharmacist.

If you take too much of it (overdose)

Immediately telephone your doctor or Poisons Information Centre (telephone Australia 13 11 26 or New Zealand 0800 764 766) for advice, or go to Accident and Emergency at the nearest hospital, if you think that you or anyone else may have taken too much Carbaglu. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.

While you are taking CARBAGLU

Things you must do

Your doctor may ask you to have your liver, kidney, heart functions and blood tested from time to time to make sure the medicine is working to prevent unwanted side effects.

If you become pregnant while you are taking Carbaglu, contact your doctor immediately.

If you are about to be started on any new medication, remind your doctor and pharmacist that you are taking Carbaglu.
