INDICATIONS
GaviLyte-G is indicated for bowel cleansing prior to
colonoscopy and barium enema X-ray examination.
DOSAGE AND ADMINISTRATION
The recommended dose for adults is 4 liters of GaviLyte-G
solution prior to gastrointestinal examination, as ingestion of this dose produces
a satisfactory preparation in over 95% of patients. Ideally, the patients
should fast for approximately three or four hours priorto GaviLyte-G administration,
but in no case should solid food be given for at least two hours before the
solution is given.
GaviLyte-G is usually administered orally, but may be given
via nasogastric tube to patients who are unwilling or unable to drink the
solution. Oral administration is at a rate of 240 mL (8oz.) every 10
minutes, until 4 liters are consumed or the rectal effluent is clear. Rapid
drinking of each portion is preferred to drinking small amounts continuously. Nasogastric
tube administration is at the rate of 20 to 30 mL per minute (1.2 to
1.8 liters per hour). The first bowel movement should occur approximately one hour
after the start of GaviLyte-G administration.
Various regimens have been used. One method is to schedule
patients for examination in midmorning or later, allowing the patients three
hours for drinking and an additional one hour period for complete bowel evacuation.
Another method is to administer GaviLyte-G on the evening before the
examination, particularly if the patient is to have a barium enema
Preparation Of The solution
GaviLyte-G is prepared by filing the container to the 4
liter mark with water and shaking vigorously several times to ensure that the
ingredients are dissolved. Dissolution is facilitated by using lukewarm water. The
solution is more palatable if chilled before admin istration. The reconstituted
solution should be refrigerated and used within 48 hours. Discard any unused
portion.
