Why is Lovastatin
prescribed? Lovastatin is used, along with diet, to lower
cholesterol levels in people with primary hypercholesterolemia
(too much cholesterol in the bloodstream). High cholesterol
levels foster the buildup of artery-clogging plaque, which can
be especially dangerous when it collects in the vessels
serving the muscles of the heart. Lovastatin is prescribed to
prevent this problem--called coronary heart disease--or to
slow its advance if the arteries are already clogging
up.
Most important fact about
Lovastatin Lovastatin is usually prescribed only if diet,
exercise, and weight-loss fail to bring your cholesterol
levels under control. It's important to remember that
Lovastatin is a supplement--not a substitute--for these other
measures. To get the full benefit of the medication, you need
to stick to the diet and exercise program prescribed by your
doctor.
How should you take
Lovastatin? Lovastatin should be taken with
meals.
--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...
Protect Lovastatin from light. Store at
room temperature. Keep container tightly closed.
What side effects may
occur? Lovastatin is generally well tolerated. Any side
effects that have occurred have usually been mild and
short-lived. If any side effects develop or change in
intensity, inform your doctor as soon as possible. Only your
doctor can determine if it is safe for you to continue taking
Lovastatin.

pain/cramps, altered sense of taste, blurred vision,
constipation, diarrhea, dizziness, gas, headache, heartburn,
indigestion, itching, muscle cramps, muscle pain, muscle

Why should Lovastatin not be
prescribed? If you are sensitive to or have ever had an
allergic reaction to Lovastatin or similar anticholesterol
drugs, you should not take this medication. Make sure that
your doctor is aware of any drug reactions that you have
experienced.
Unless you are directed to do so by your
doctor, do not take this medication if you are being treated
for liver disease.
Do not take this drug if you are pregnant
or nursing.
Special warnings about Lovastatin If
you are being treated for any disease that contributes to
increased blood cholesterol, such as hypothyroidism, diabetes,
nephrotic syndrome (kidney and blood vessel disorder),
dysproteinemia (an excess of protein in the blood), or liver
disease, your doctor will closely monitor your reaction to
Lovastatin.
It is recommended that liver function
tests be performed by your doctor before treatment with
Lovastatin begins, at 6 and 12 weeks after your treatment has
started or your dosage has been raised, and periodically
(about 6-month intervals) thereafter.
If you are planning to have elective
surgery, Lovastatin should be discontinued a few days before
the operation. This drug should be used with caution if you
consume substantial quantities of alcohol or have a past
history of liver disease.
Possible food and drug interactions when
taking Lovastatin Lovastatin tends to enhance the
blood-thinning effect of Coumadin. In rare instances, it can
also cause muscle pain and potential kidney damage when
combined with the following:
Clarithromycin (Biaxin) Clofibrate
(Atromid-S) Cyclosporine (Sandimmune,
Neoral) Erythromycin (E.E.S., PCE, others) Fenofibrate
(Tricor) Fluconazole (DiFlucan) Gemfibrozil
(Lopid) Itraconazole (Sporanox) Ketoconazole
(Nizoral) Nefazodone (Serzone) Nicotinic acid or niacin
(Niaspan) Protease inhibitors (a type of drug for HIV) such
as Agenerase, Crixivan, Fortovase, Invirase, Norvir, and
Viracept
If you are taking Lovastatin with any of
these drugs, (or with large quantities of grapefruit juice),
alert your doctor immediately at the first sign of muscle
pain, tenderness, or weakness, especially if accompanied by
fever or general body discomfort. If you need to take
erythromycin, Biaxin, Nizoral, or Sporanox, the doctor may
temporarily take you off Lovastatin.
Special information if you are pregnant
or breastfeeding You should take Lovastatin only if
pregnancy is highly unlikely. If you become pregnant while
taking this drug, discontinue using it and notify your
physician immediately. There may be a potential hazard to the
developing baby. This medication may appear in breast milk and
may have an effect on nursing infants. If this medication is
essential to your health, you should discontinue breastfeeding
until your treatment with this medication is
finished.
Recommended dosage ADULTS
The recommended starting dose is 20
milligrams once a day, taken with the evening meal. The
maximum recommended dose is 80 milligrams per day, taken as a
single dose or divided into smaller doses, as determined by
your doctor. Adjustments to any dose, as determined by your
doctor, should be made at intervals of 4 weeks or more.
If you are taking Lopid, Atromid-S,
Tricor or nicotinic acid in combination with Lovastatin, your
dose of Lovastatin should not exceed 20 milligrams per

Cholesterol levels should be monitored
periodically by your doctor, who may decide to reduce the dose
if your cholesterol level falls below the targeted
range.
If you have reduced kidney function, your
