Synthroid – Levothroid
Levothyroxine
Other brand names: Levothroid, Levoxyl, Unithroid
Why is this drug prescribed?
Synthroid, a synthetic thyroid hormone may be given in any of the following
cases:
If your own thyroid gland is not making enough hormone;
If you have an enlarged thyroid (a goiter) or are at risk for developing a
goiter;
If you have certain cancers of the thyroid;
If your thyroid production is low due to surgery, radiation, certain drugs, or
disease of the pituitary gland or hypothalamus in the brain.
Most important fact about this drug
If you are taking Synthroid to make up for a lack of natural hormone, it is
important to take it regularly at the same time every day. You will probably
need to take it for the rest of your life.
How should you take this medication?
Take Synthroid as a single dose, preferably on an empty stomach, one-half to one
hour before breakfast. The drug is absorbed better on an empty stomach.
If an infant or child cannot swallow whole tablets, you may crush a Synthroid
tablet and mix it into 1 or 2 teaspoonfuls of water.
While taking Synthroid, your doctor will perform periodic blood tests to
determine whether you are getting the right amount.
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. If you miss 2 or more doses in a row, consult your doctor.
Storage instructions...
Keep this medication in a tightly closed container. Store it at room
temperature, away from light and moisture.
What side effects may occur?
Side effects from Synthroid, other than overdose symptoms, are rare. People who
are treated with Synthroid may initially lose some hair, but this effect is
usually temporary. You may have an allergic reaction such as a rash or hives.
Children may have an increase in pressure within the skull. Excessive dosage or
a too rapid increase in dosage may lead to overstimulation of the thyroid gland.
Notify your doctor immediately if you develop any if the following symptoms.
Symptoms of overstimulation:
Abdominal cramps, anxiety, changes in appetite, change in menstrual periods,
chest pain, diarrhea, emotional instability, fatigue, fever, flushing, hair
loss, headache, heart attack or failure, heat intolerance, hyperactivity,
increased heart rate, irregular heartbeat, irritability, muscle weakness,
nausea, nervousness, palpitations, shortness of breath, sleeplessness, sweating,
tremors, vomiting, weight loss
Why should this drug not be prescribed?
You should not be treated with Synthroid if you are hypersensitive to thyroid
hormone; your thyroid gland is making too much thyroid hormone; you have had a
recent heart attack; or your adrenal glands are not making enough corticosteroid
hormone. If you are sensitive to dyes, you can take the Synthroid 50-microgram
tablet, which is made without color additives.
Although Synthroid will speed up your metabolism, it is not effective as a
weight-loss drug and should not be used as such. An overdose may cause
life-threatening side effects, especially if you take Synthroid with an
appetite-suppressant medication.
Special warnings about this medication
Synthroid has profound effects on the body. Make sure your doctor is aware of
all your medical problems, especially heart disease, clotting disorders,
diabetes, and disorders of the adrenal or pituitary glands. The doctor will also
need to know about any allergies you may have to food or medicine, and will ask
for the names of any medications you take, whether prescription or
over-the-counter.
You should receive low doses of Synthroid, under very close supervision, if you
are an older person, or if you suffer from high blood pressure, angina (chest
pain caused by a heart condition), or other types of heart disease. If you
develop chest pain or additional circulatory problems, your dosage may have to
be reduced.
If you have diabetes, or if your body makes insufficient adrenal corticosteroid
hormone, Synthroid will tend to make your symptoms worse. If you take medication
for any of these disorders, the dosage will probably have to be adjusted once
you begin taking Synthroid. If diabetes is the problem, you should immediately
report to your doctor any change in your glucose readings.
Postmenopausal women on long-term Synthroid therapy may suffer a loss of bone
density, increasing the danger of osteoporosis (brittle bones). To minimize the
loss, the doctor will prescribe the lowest dosage needed to control symptoms of
thyroid deficiency.
Synthroid may cause seizures at the beginning of treatment, although this is
rare. You may also notice some hair loss at first, but this is temporary.
It may take a few weeks for Synthroid to begin working, and you may not see any
change in your symptoms until then.
Tell your doctor or dentist you are taking Synthroid before you have surgery of
any kind.
Tell your doctor if you become pregnant while you are taking Synthroid. Your
dose may need to be increased.
Do not switch to another brand of levothyroxine without consulting your doctor.
Excessive doses of Synthroid in infants may cause the top of the skull to close
too early. In children, overtreatment can stunt growth.

Special information
if you are pregnant or breastfeeding
If you need to take Synthroid because of a thyroid hormone deficiency, you can
continue to take the medication during pregnancy. In fact, your doctor will test
you regularly and may increase your dose. Once your baby is born, you may
breastfeed while continuing to take carefully regulated doses of Synthroid.
Recommended dosage
Your doctor will tailor the dosage to meet your individual requirements, taking
into consideration the status of your thyroid gland and other medical conditions
you may have. Older adults often require somewhat smaller doses. To make sure
the dosage is right for you, the doctor will monitor your thyroid hormone level
with periodic blood tests.
Overdosage
An overdose of Synthroid can produce the same symptoms of overstimulation listed
under "What side effects may occur?" Confusion and disorientation are also
possible, and there have been reports of stroke, shock, coma, and death. If you
suspect a massive overdose, seek emergency medical attention immediately.
