Osmolax Osmotic Laxative Powder 17g x 30

AUST-R 203142

How OsmoLax works
The active ingredient in OsmoLax is called macrogol 3350. Macrogol is considered to be the ‘gold standard’ for the treatment of constipation, especially in children.1 In fact, macrogol containing laxatives are the most prescribed type of laxative by Australian doctors.2

Lubricates | Bulks | Softens | Stimulates
OsmoLax restores the body’s natural rhythm. It is virtually unabsorbed so it remains in the bowel and directs water into the stool. This lubricates and softens, as well as bulks the stool which stimulates the urge to go to the toilet.
The result is a natural and comfortable bowel movement.

Why is Osmolax different?
Some other macrogol products contain electrolytes and may have a salty taste.
OsmoLax does not contain any electrolytes, so it does not have a salty taste. OsmoLax can be mixed with any liquid, hot or cold.

OsmoLax is free from gluten, lactose, yeast and has no artificial flavours, colours or sweeteners.

Clinical evidence
OsmoLax is identical to a macrogol 3350 product available in the U.S. that has beenclinically tested in over 20 clinical studies. The studies confirm that macrogol 3350 is clinically proven and very well tolerated. In addition, some studies compared the product to lactulose where it was found to be as effective but much better tolerated. The clinical studies have been done in children as well as adults and in various degrees of constipation in both short term and long term use.

One clinical study1 compared macrogol* without salts to macrogol with salts. It was found that there was no difference in terms of effectiveness and side effects. Importantly, there were no clinically significant differences in plasma electrolyte levels. 85% of patients in the group taking the macrogol product without salts were willing to continue treatment compared to 63% in the group taking the macrogol product with salts, because of the salty taste of the latter.

Macrogol based laxatives are considered the gold standard for the treatment of constipation in children.2 In a study which compared macrogol without salts to macrogol with salts in children, 43% of children rated the taste of macrogol without salts as very good compared to only 2% in the group taking macrogol with salts.

There was no difficulty in administering macrogol without salts in 96% of patients compared to 52% of patients taking macrogol with salts.

* This study was done with macrogol 4000 which is a similar product to macrogol 3350.

For adults and children over the age of 12 years:
One level 17g measuring scoop mixed with 1 cup (approximately 240mL) of liquid once daily. This can be increased to a maximum of 2 doses of 17g daily, dependent on the severity of your constipation. For chronic constipation, the dose may be reduced to one 8.5g scoop mixed with ½ cup (approximately 120mL) of liquid daily, according to individual response.

For children aged 6 to 12 years:
The usual starting dose is two level 8.5g measuring scoops (or one 17g scoop), mixed with 1 cup (approximately 240mL) of liquid once daily. The dose should be adjusted up or down as required to produce regular soft stools. The maximum dose should not exceed three 8.5g scoops (equivalent to 25.5g) daily.

For children aged 4 to 5 years:
The usual starting dose is one level 8.5g measuring scoop, mixed with ½ cup (approximately 120mL) of liquid once daily. This can be increased to a maximum of two 8.5g scoops (equivalent to 17g) daily if required.

OsmoLax is not recommended for children under 4 years of age.

Directions for Use
Add OsmoLax powder (see dosage above) to any beverage (hot or cold), such as water, juice, soft drinks, coffee or tea. Stir until dissolved and then drink. If desired, the solution may be stored covered in the fridge. Discard any solution that is not used within 6 hours. Drink plenty of water. Increase fibre in the diet during treatment, except in cases of medication induced constipation (e.g. codeine).

Prolonged use of laxatives is undesirable and may lead to dependence. If symptoms persist seek medical advice.

If you are pregnant or breastfeeding, check with your health care professional before taking OsmoLax.
