Why is Glucotrol prescribed?
Glucotrol is an oral antidiabetic medication used to treat type 2
(non-insulin-dependent) diabetes. In diabetics either the body does
not make enough insulin or the insulin that is produced no longer
works properly.
There are actually two forms of diabetes: type 1
insulin-dependent and type 2 non-insulin-dependent. Type 1 usually
requires insulin injections for life, while type 2 diabetes can
usually be treated by dietary changes and/or oral antidiabetic
medications such as Glucotrol. Apparently, Glucotrol controls
diabetes by stimulating the pancreas to secrete more insulin. If you
suffer from type 1 diabetes, you will need to use insulin and will
not be able to use Glucotrol. Occasionally, type 2 diabetics must
take insulin injections on a temporary basis, especially during
stressful periods or times of illness.
Most important fact about Glucotrol
Always remember that Glucotrol is an aid to, not a substitute
for, good diet and exercise. Failure to follow a sound diet and
exercise plan can lead to serious complications, such as dangerously
high or low blood sugar levels. Remember, too, that Glucotrol is
not an oral form of insulin, and cannot be used in place of
insulin.
How should you take Glucotrol?
In general, to achieve the best control over blood sugar levels,
Glucotrol should be taken 30 minutes before a meal. However, the
exact dosing schedule as well as the dosage amount must be
determined by your physician.
Glucotrol XL should be taken with breakfast. Swallow the tablets
whole; do not chew, crush, or divide them. Do not be alarmed if you
notice something that looks like a tablet in your stool<96>it will
be the empty shell that has been eliminated.
--If you miss a dose...
Take it as soon as you remember. If it is almost time for your
next dose, skip the one you missed and go back to your regular
schedule. Never take 2 doses at the same time.
--Storage instructions...
Glucotrol should be stored at room temperature and protected from
moisture and humidity.
Glucotrol side effects
Side effects from Glucotrol are rare and seldom require
discontinuation of Glucotrol.
- Side effects may include:
Constipation,
diarrhea,
dizziness,
drowsiness,
gas,
headache,
hives,
itching,
low blood sugar,
nervousness,
sensitivity to light,
skin rash and eruptions,
stomach pain,
tremor
Glucotrol and Glucotrol XL, like all oral antidiabetic drugs, can
cause low blood sugar. This risk is increased by missed meals,
alcohol, other diabetes medications, and excessive exercise. Low
blood sugar is also more likely in older people, those with kidney
or liver problems, and those with poorly functioning adrenal or
pituitary glands. To avoid low blood sugar, you should closely
follow the dietary and exercise regimen suggested by your physician.
- Symptoms of mild low blood sugar may include:
Blurred vision,
cold sweats,
dizziness,
fast heartbeat,
fatigue,
headache,
hunger,
light-headedness,
nausea,
nervousness
- Symptoms of more severe low blood sugar may include:
Coma,
disorientation,
pale skin,
seizures,
shallow breathing
Ask your doctor what steps you should take if you experience mild
hypoglycemia. If symptoms of severe low blood sugar occur, contact
your doctor immediately. Severe hypoglycemia should be considered a
medical emergency, and prompt medical attention is essential.
Why should Glucotrol not be prescribed?
You should not take Glucotrol if you have had an allergic
reaction to it previously.
Glucotrol will be stopped if you are suffering from diabetic
ketoacidosis (a life-threatening medical emergency caused by
insufficient insulin and marked by excessive thirst, nausea,
fatigue, pain below the breastbone, and a fruity breath).
Special warnings about Glucotrol
It's possible that drugs such as Glucotrol may lead to more heart
problems than diet treatment alone, or diet plus insulin. If you
have a heart condition, you may want to discuss this with your
doctor.
If you are taking Glucotrol, you should check your blood and
urine periodically for the presence of abnormal sugar (glucose)
levels.
Even people with well-controlled diabetes may find that injury,
infection, surgery, or fever results in a lack of control over their
diabetes. In these cases, the physician may recommend that you stop
taking Glucotrol temporarily and use insulin instead.
Glucotrol may not work well in patients with poor kidney or liver
function.
In addition, the effectiveness of any oral antidiabetic,
including Glucotrol, may decrease with time. This may occur because
of either a diminished responsiveness to Glucotrol or a
worsening of the diabetes.
Be careful taking the extended-release form of the drug,
Glucotrol XL, if you have any narrowing in your stomach or
intestines. Also, if you have any stomach or intestinal disease,
Glucotrol XL may not work as well.
Possible food and drug interactions when taking Glucotrol
It is essential that you closely follow your physician's dietary
guidelines and that you inform your physician of any medication,
either prescription or nonprescription, that you are taking.
Specific medications that affect Glucotrol include:
Airway-opening drugs such as Sudafed
Antacids such as Mylanta
Aspirin
Chloramphenicol (Chloromycetin)
Cimetidine (Tagamet)
Clofibrate (Atromid-S)
Corticosteroids such as prednisone (Deltasone)
Diuretics such as HydroDIURIL
Estrogens such as Premarin
Fluconazole (Diflucan)
Gemfibrozil (Lopid)
Heart and blood pressure medications called beta blockers such
as Tenormin and Lopressor
Heart medications called calcium channel blockers such as
Cardizem and Procardia XL
Isoniazid (Rifamate, Rimactane)
Itraconazole (Sporanox)
MAO inhibitors (antidepressant drugs such as Nardil and Parnate)
Major tranquilizers such as Thorazine and Mellaril
Miconazole (Monistat)
Nicotinic acid (Nicobid)
Nonsteroidal anti-inflammatory drugs such as Motrin and Naprosyn
Oral contraceptives
Phenytoin (Dilantin)
Probenecid (Benemid)
Rifampin (Rifadin)
Sulfa drugs such as Bactrim and Septra
Thyroid medications such as Synthroid
Warfarin (Coumadin)
Alcohol must be used carefully, since excessive alcohol
consumption can cause low blood sugar.
Special information if you are pregnant or breastfeeding
The effects of Glucotrol during pregnancy have not been
adequately studied. Therefore, if you are pregnant, or planning to
become pregnant, you should take Glucotrol only on the advice of
your physician. Since studies suggest the importance of maintaining
normal blood sugar (glucose) levels during pregnancy, your physician
may prescribe insulin during pregnancy. To minimize the risk of low
blood sugar in newborn babies, Glucotrol, if taken during pregnancy,
should be discontinued at least one month before the expected
delivery date.
Although it is not known if Glucotrol appears in breast milk,
other oral antidiabetics do. Because of the potential for
hypoglycemia in nursing infants, your doctor may advise you either
to discontinue Glucotrol or to stop nursing. If Glucotrol is
discontinued and if diet alone does not control glucose levels, your
doctor may prescribe insulin.
Recommended dosage for Glucotrol
Dosage levels must be determined by each patient's needs.
ADULTS
Overdosage
An overdose of Glucotrol can cause low blood sugar. (See side
effects section for symptoms.) Eating sugar or a sugar-based product
will often correct the condition. Otherwise, seek medical attention
immediately.
