FULL PRESCRIBING INFORMATION

POLYETHYLENE GLYCOL 3350 DESCRIPTION

A white powder for reconstitution. Polyethylene Glycol 3350 NF (Polyethylene Glycol 3350

Powder For Oral Solution) is a synthetic polyglycol having an average molecular weight of

3350. The actual molecular weight is not less than 90.0 percent and not greater than 110.0

percent of the nominal value. The chemical formula is HO(C2H4O)nH in which n represents

the average number of oxyethylene groups. Below 55°C it is a free flowing white powder

freely soluble in water. Polyethylene Glycol 3350 NF is an osmotic agent for the treatment

of constipation.

CLINICAL PHARMACOLOGY

Pharmacology: Polyethylene Glycol 3350 NF is an osmotic agent which causes water to be

retained with the stool. Essentially, complete recovery of Polyethylene Glycol 3350 NF was

shown in normal subjects without constipation. Attempts at recovery of Polyethylene Glycol

3350 NF in constipated patients resulted in incomplete and highly variable recovery. In vitro

study showed indirectly that Polyethylene Glycol 3350 NF was not fermented into hydrogen

or methane by the colonic microflora in human feces. Polyethylene Glycol 3350 NF appears

to have no effect on the active absorption or secretion of glucose or electrolytes. There is no

evidence of tachyphylaxis.

CLINICAL TRIALS

In one study, patients with less than 3 bowel movements per week were randomized to

Polyethylene Glycol 3350 NF, 17 grams, or placebo for 14 days. An increase in bowel

movement frequency was observed for both treatment groups during the first week of

treatment. Polyethylene Glycol 3350 NF was statistically superior to placebo during the

second week of treatment. In another study, patients with 3 bowel movements or less per

week and/or less than 300 grams of stool per week were randomized to 2 dose levels of

Polyethylene Glycol 3350 NF or placebo for 10 days each. Success was defined by an

increase in both bowel movement frequency and daily stool weight. For both parameters,

superiority of the 17 gram dose of Polyethylene Glycol 3350 NF over placebo was

demonstrated.

POLYETHYLENE GLYCOL 3350 INDICATIONS AND USAGE

For the treatment of occasional constipation. This product should be used for 2 weeks or

less or as directed by a physician.

POLYETHYLENE GLYCOL 3350 CONTRAINDICATIONS

Polyethylene Glycol 3350 NF is contraindicated in patients with known or suspected bowel

obstruction and patients known to be allergic to polyethylene glycol.

WARNINGS

Patients with symptoms suggestive of bowel obstruction (nausea, vomiting, abdominal

pain or distention) should be evaluated to rule out this condition before initiating

Polyethylene Glycol 3350 NF therapy.

PRECAUTIONS

General

Patients presenting with complaints of constipation should have a thorough

medical history and physical examination to detect associated metabolic, endocrine and

neurogenic conditions and medications. A diagnostic evaluation should include a structural

examination of the colon. Patients should be educated about good defecatory and eating

habits (such as high fiber diets) and lifestyle changes (adequate dietary fiber and fluid

intake, regular exercise) which may produce more regular bowel habits.

Polyethylene Glycol 3350 NF should be administered after being dissolved in approximately

4 to 8 ounces of water, juice, soda, coffee or tea.

Information for patients

Polyethylene Glycol 3350 NF softens the stool and increases the

frequency of bowel movements by retaining water in the stool. It should always be taken by

mouth after being dissolved in 4 to 8 ounces of water, juice, soda, coffee, or tea. Should

unusual cramps, bloating, or diarrhea occur, consult your physician.

Two to 4 days may be required to produce a bowel movement. This product should be used

for 2 weeks or less or as directed by your physician. Prolonged, frequent or excessive use of

Polyethylene Glycol 3350 NF may result in electrolyte imbalance and dependence on laxatives.

Laboratory tests

No clinically significant effects on laboratory tests have been demonstrated.

Interactions

Drug interactions

No specific drug interactions have been demonstrated.

Carcinogenesis, mutagenesis, impairment of fertility

Long term carcinogenicity studies,

genetic toxicity studies or reproductive toxicity studies in animals have not been performed

with Polyethylene Glycol 3350 NF.

Pregnancy

Category C. Animal reproductive studies have not been performed with Polyethylene Glycol 3350 NF.

It is also not known whether Polyethylene Glycol 3350 NF can cause fetal harm when

administered to a pregnant woman, or can affect reproductive capacity. Polyethylene Glycol

3350 NF should only be administered to a pregnant woman if clearly needed.

Pediatric use

Safety and effectiveness in pediatric patients has not been established.

Geriatric use

There is no evidence for special considerations when Polyethylene Glycol

3350 NF is administered to elderly patients. In geriatric nursing home patients a higher

incidence of diarrhea occurred at the recommended 17 g dose. If diarrhea occurs

Polyethylene Glycol 3350 NF should be discontinued.

POLYETHYLENE GLYCOL 3350 ADVERSE REACTIONS

Nausea, abdominal bloating, cramping and flatulence may occur. High doses may produce

diarrhea and excessive stool frequency, particularly in elderly nursing home patients.

Patients taking other medications containing polyethylene glycol have occasionally

developed urticaria suggestive of an allergic reaction.

DRUG ABUSE AND DEPENDENCE

Overdosage

There have been no reports of accidental overdosage. In the event of overdosage, diarrhea

would be the expected major event. If an overdose of drug occurred without concomitant

ingestion of fluid, dehydration due to diarrhea may result. Medication should be terminated

and free water administered. The oral LD50 is > 50 gm/kg in mice, rats and rabbits.

by physician) in 4 to 8 ounces of water, juice, soda, coffee, or tea. Each bottle of

Polyethylene Glycol 3350 NF is supplied with a dosing cup marked to contain 17 grams of
