Picolax® is a powder that contains sodium picosulfate, a laxative that works by increasing the activity of the intestine. Picolax® also contains magnesium citrate, another type of laxative that works by holding back fluid in the bowel to provide a wash-out effect.
Picolax® is used in adults, adolescents and children from the age of 1 year to clear the bowel before an x-ray examination, endoscopy or surgery when judged clinical necessary.
In these conditions, the movement of the contents of the bowel may be impaired or prevented. Symptoms include nausea, vomiting, diarrhoea, abdominal pain, tenderness or swelling, colicky pain and fever.
Talk to your doctor or pharmacist before taking Picolax®:
You should make sure to drink a sufficient amount of fluid and electrolytes during the course of the treatment. This is particularly important if you are younger than 18 years, elderly or physically weak.
If you have an early time of the day procedure, you might need to take the second dose during night and possible sleep disturbance may occur.
The period of bowel cleansing should not exceed 24 hours because longer preparation may increase the risk of water and mineral imbalance in the body.
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.
It is especially important to tell your doctor if you are taking:
If you are pregnant or breast-feeding, think you may be pregnant or are trying to have a baby, ask your doctor or pharmacist for advice before taking this medicine.
Picolax® has no effect on the ability to drive and use machines. However, you should make sure that you have access to a toilet at all times following each dose, until the effect wears off.
Each sachet contains 5 mmol (or 195 mg) potassium. You should discuss this with your doctor if you have kidney problems or you have been put on a controlled potassium diet.
This medicine also contains lactose. If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicinal product.
This medicine contains less than 1 mmol sodium (23 mg) per sachet, that is to say essentially ‘sodium-free’.
Always take Picolax® exactly as your doctor has told you. Check with your doctor if you are not sure.
Picolax® powder should be dissolved in a cup of cold water (approximately 150ml). Stir for 2-3 minutes and then drink the solution. Sometimes the solution becomes warm as Picolax® dissolves. If this happens, wait until it cools sufficiently before drinking it.
The recommended dose is one sachet taken 10 to 18 hours before your procedure and one sachet taken 4 to 6 hours before your procedure. The first sachet taken, should be followed by at least five 250 ml drinks of clear liquids (not only water) spread over several hours and the second sachet taken, should be followed by at least three 250 ml drinks of clear liquids (not only water) spread over several hours. You may drink clear liquids (not only water) until 2 hours before your procedure. Do not drink only water.
For the timing of dosing in children, refer to the instructions given for adults
A measuring spoon is provided with the product.

To measure the dose with the measuring spoon:
You should expect frequent, loose bowel motions to start at any time after taking a dose of Picolax®. Please ensure that you have access to a toilet at all times following each dose, until the effects wear off.
In order to replace fluid lost from the body, it is important to drink plenty of clear liquids (not only water) throughout the treatment with Picolax® until the bowel movements have ceased. In general, you should try to drink clear liquids (not only water) when you are thirsty. Do not drink only water.
Clear liquids should include a variety of fruit juice without pulp, soft drinks, clear soup, tea, coffee (without milk, soy or cream) and water. Do not drink only water.
The success of your hospital procedure that you undergo depends on the bowel being as clear as possible. The procedure may need to be repeated if you do not achieve a clear bowel. You should always follow the dietary instructions given by your doctor.
PICOLAX® should not be used as a routine laxative.
If you have taken more Picolax® than you should, contact your doctor immediately or go to the casualty department at your nearest hospital.
