Print Friendly, PDF & Email

Generic Name: olsalazine sodium
Product Name: Dipentum

Indication: What Dipentum is used for

Dipentum is used to treat a disease of the bowel called ulcerative colitis.

Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed it for another reason.

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

This medicine is not addictive.

Action: How Dipentum works

Dipentum belongs to a group of medicines called aminosalicylates.

Olsalazine consists of two molecules of 5-aminosalicylic acid (5-ASA) covalently bound through an azo-bond. Olsalazine is activated exclusively in the colon. Colonic bacterial azoreductases split the azo-bond converting olsalazine into 5-ASA, the clinically active moiety. The mechanism of action of 5-ASA in the treatment of ulcerative colitis remains unknown.

Dipentum capsules contain 250 mg of olsalazine sodium as the active ingredient. The capsules also contain magnesium stearate, gelatin, caramel (E150), titanium dioxide (E171), and iron oxide (E172).

Dipentum tablets contain 500 mg of olsalazine sodium as the active ingredient. The tablets also contain magnesium stearate, silica-colloidal anhydrous, povidone, and crospovidone.

Dipentum tablets and capsules do not contain gluten, lactose, sucrose, tartrazine or other azo dyes.

How to take Dipentum

Follow all directions given to you by your doctor or pharmacist carefully. They may differ from the information contained here.

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

How much to take

Your doctor will tell you how many capsules or tablets you will need to take each day. This may depend on your condition and whether or not you are taking any other medicines.

Your doctor may start you on a low dose of 250 mg to 500 mg a day before gradually increasing your dose to 2 g to 3 g a day (given in divided doses). A single dose should not exceed 1 g.

Once your condition is under control your doctor may reduce your dose to 1 g a day.

Do not switch from Dipentum tablets to capsules or vice versa without first talking to your doctor.

How to take it

Swallow the tablets or capsules whole with a full glass of water.

When to take it

Take Dipentum soon after food.

Take your medicine 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.

How long to take it

Continue taking your medicine for as long as your doctor tells you. This medicine helps to control your condition but does not cure it. It is important to keep taking your medicine even if you feel well.

If you forget to take it

If you forget to take your Dipentum dose, skip the dose you missed and take your next dose when you are meant to.

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 have trouble remembering to take your medicine, ask your pharmacist for some hints.

If you take too much

Immediately telephone your doctor or the Poisons Information Centre (telephone Australia 13 11 26 or New Zealand 0800 POISON or 0800 764766) 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 Dipentum. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.

Symptoms of an overdose may include:

  • Nausea;
  • Vomiting;
  • Diarrhoea.

Go to your doctor immediately if you have a fever, sore throat, mouth ulcers, bruising or bleeding while using Dipentum. These symptoms may indicate that you have developed a blood problem.

Keep all your doctor’s appointments so that your progress can be checked. Your doctor may do some blood tests and may want to check your kidney and liver function from time to time.

Things you must not do

Do not take Dipentum to treat any other complaints unless advised by your doctor.

Do not give your medicine to anyone else, even if they have the same condition as you.
