Warnings

The dose of Eltroxin (Levothyroxine) depends on how much of the hormone is needed to bring blood levels back to the normal range. This is determined by blood tests that are done in a laboratory. The starting dose will depend on your general physical condition and the severity and length of time that you have been experiencing symptoms of low thyroid hormone levels.

You should take Eltroxin (Levothyroxine) once a day at the same time every day to ensure a consistent effect. Cotton seed meal, dietary fibre, soybean flour (infant formula), or walnuts may decrease the absorption of Eltroxin (Levothyroxine).

Signs that you may be getting too much thyroid hormone may include chest pain, increased heart rate, palpitations, excessive sweating, heat intolerance, and nervousness. If you think your dose of thyroid hormone may be too high, consult your doctor as soon as possible.

Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones given here, do not change the way that you are using the medication without consulting your doctor.

It is important to take Eltroxin (Levothyroxine) exactly as recommended by your doctor. If you miss a dose, take it as soon as possible and continue with your regular schedule. If it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.

Store Eltroxin (Levothyroxine) at room temperature, protect it from light and moisture, and keep it out of the reach of children.

Do not dispose of medications in wastewater (e.g. down the sink or in the toilet) or in household garbage. Ask your pharmacist how to dispose of medications that are no longer needed or have expired.

stop taking one of the medications,
change one of the medications to another,
change how you are taking one or both of the medications, or
leave everything as is.

An interaction between two medications does not always mean that you must stop taking one of them. Speak to your doctor about how any drug interactions are being managed or should be managed.

Medications other than those listed above may interact with Eltroxin (Levothyroxine). Tell your doctor or prescriber about all prescription, over-the-counter (non-prescription), and herbal medications that you are taking. Also tell them about any supplements you take. Since caffeine, alcohol, the Nicotine from cigarettes, or street drugs can affect the action of many medications, you should let your prescriber know if you use them.

Before you begin using a medication, be sure to inform your doctor of any medical conditions or Allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use Eltroxin (Levothyroxine).

Bone density: Eltroxin (Levothyroxine) can cause bones to lose thickness. If you have an increased risk for Osteoporosis (bone thinning) or are taking medications that reduce bone thickness (e.g., Prednisone or antiseizure medications), before you start taking Eltroxin (Levothyroxine), discuss with your doctor how Eltroxin (Levothyroxine) may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Eltroxin (Levothyroxine), and whether any special monitoring is needed.

Your doctor may monitor your bone thickness while you are taking Eltroxin (Levothyroxine).

Diabetes: Eltroxin (Levothyroxine) raises blood sugar levels. For people with diabetes, this may result in an increase in the requirements for insulin or antidiabetes medications. If you have diabetes or are at an increased risk of developing diabetes, discuss with your doctor how Eltroxin (Levothyroxine) may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Eltroxin (Levothyroxine), and whether any special monitoring is needed.

You may need to monitor your blood sugar more closely when starting Eltroxin (Levothyroxine) or changing doses of Eltroxin (Levothyroxine).

Heart disease: When starting Eltroxin (Levothyroxine), people with heart disease may be started on a lower dosage as it may cause the heart to work harder than it has been used to. If you have heart disease, discuss with your doctor how Eltroxin (Levothyroxine) may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Eltroxin (Levothyroxine), and whether any special monitoring is needed.

Signs of getting too much or too little medication: Contact your doctor as soon as possible if you notice any signs of getting too much medication (such as chest pain, confusion, fast or irregular heartbeat, mood swings, muscle weakness, psychosis, extreme restlessness, yellow eyes or skin, or shortness of breath) or signs of not getting enough medication (such as clumsiness, coldness, Constipation, dry, puffy skin, listlessness, muscle aches, sleepiness, tiredness, weakness, or weight gain).

Weight loss: Eltroxin (Levothyroxine) should not be used for weight loss. Large doses of Eltroxin (Levothyroxine) can cause serious ore even life threatening side effects especially when taken together with other medications for weight loss.

Pregnancy: Eltroxin (Levothyroxine) should be taken throughout pregnancy to regulate the levels of thyroid hormone for the pregnant mother and the developing baby. If you become pregnant while taking Eltroxin (Levothyroxine), contact your doctor as soon as possible. Your doctor may want to monitor your thyroid function more closely while you are pregnant.

Breast-feeding: Only a small amount of thyroid hormone is passed into breast milk. The use of appropriate amounts of Eltroxin (Levothyroxine) by breast-feeding women has not been shown to cause harm for breast-fed babies.
