Why
is Questran prescribed?
Questran
is used to lower cholesterol levels in the blood of people with
primary hypercholesterolemia (too much LDL cholesterol). Hypercholesterolemia
is a genetic condition characterized by a lack of the LDL receptors
that remove cholesterol from the bloodstream.
This
drug can be used to lower cholesterol levels in people who also
have hypertriglyceridemia, a condition in which an excess of
fat is stored in the body.
This
drug may also be prescribed to relieve itching associated with
gallbladder obstruction.
It
is available in two forms: Questran and Questran Light. The
same instructions apply to both.

Most
important fact about Questran
It's
important to remember that Questran is a supplement to--not
a substitute for--diet, exercise, and weight loss. To get the
full benefit of the medication, you need to stick to the diet
and exercise program prescribed by your doctor. All these efforts
to keep your cholesterol levels normal are important because
together they may lower your risk of heart disease.
--------------------------------------------------------------------
How
should you take Questran?
Never
take Questran in its dry form. Always mix it with water or other
liquids before taking it. For Questran, use 2 to 6 ounces of
liquid per packet or level scoopful; for Questran Light, use
2 to 3 ounces. Soups or fruits with a high moisture content,
such as applesauce or crushed pineapple, can be used in place
of beverages.
--If
you miss a dose...
Take
the forgotten dose as soon as you remember. If it is almost
time for the next dose, skip the one you missed and go back
to your regular schedule. Never try to "catch up"
by doubling the dose.
--Storage

Special
warnings about Questran
If
you have phenylketonuria, a genetic disorder, check with your
doctor before taking Questran Light because this product contains
phenylalanine.
If
you are being treated for any disease that contributes to increased
blood cholesterol, such as hypothyroidism (reduced thyroid function),
diabetes, nephrotic syndrome (kidney and blood vessel disorder),
dysproteinemia, obstructive liver disease, or alcoholism, or
if you are taking any drugs that may raise cholesterol levels,
consult your doctor before taking this medication. Caution is
also in order if your kidney function is poor.
Questran
should begin to reduce cholesterol levels during the first month
of therapy. If adequate reduction of cholesterol is not obtained,
your doctor may increase the dosage or add other cholesterol-lowering
drugs. Therefore, it is important that your doctor check your
progress regularly.
Questran
does not cure the tendency to have high cholesterol levels;
it merely helps control it. To maintain healthy levels, you
therefore must continue taking the drug as directed.
The
use of this medication may produce or worsen constipation and
aggravate hemorrhoids. If this happens, inform your doctor.
To prevent constipation, the doctor may increase your dosage
very slowly, and ask you to drink more fluids, take more fiber,
or take a stool softener. If severe constipation develops anyway,
the doctor may switch to a different drug.
The
prolonged use of Questran may change acidity in the bloodstream,
especially in younger and smaller individuals in whom the doses
are relatively higher. Again, it is important that you or your
child be checked by your doctor on a regular basis.
Sipping
Questran or holding it in your mouth for a long period can lead
to tooth discoloration, enamel erosion, or decay. Be sure to
brush and floss regularly.

Possible
food and drug interactions
If Questran is taken with certain other drugs, the effects of
either could be increased, decreased, or altered. It is especially
important to check with your doctor before taking Questran with
the following:
Digitalis
(Lanoxin, Crystodigin)
Estrogens and progestins (hormones)
Oral diabetes drugs such as DiaBeta and Diabinese
Penicillin G (Pentids, others)
Phenobarbital
Phenylbutazone (Butazolidin)

Spironolactone (Aldactazide, Aldactone)
Tetracycline (Achromycin V)
Thiazide-type water pills such as Diuril
Thyroid medication such as Synthroid
Warfarin (Coumadin)
Your doctor may recommend that you take other medications at
least 1 hour before or 4 to 6 hours after you take Questran.
If
you are taking a drug such as digitalis (Lanoxin), stopping
Questran could be hazardous, since you might experience exaggerated
effects of the other drug. Consult your doctor before discontinuing
Questran.
This
drug may interfere with normal digestion and absorption of fats,
including fat-soluble vitamins such as A, D, E, and K. If supplements
of vitamins A, D, E, and K are essential to your health, your
doctor may prescribe an alternative form of these vitamins.
There
are no special considerations regarding alcohol use with this
medication.

Special
information
The effects of Questran during pregnancy have not been adequately
studied. If you are pregnant or plan to become pregnant, inform
