WARNING

While Unithroid (levothyroxine) is generally considered safe and effective when used as prescribed, like any medication, it is not without potential risks. It’s crucial for individuals to be aware of these risks and discuss them with their healthcare provider. Some potential risks associated with taking Unithroid include:

• Overdose: Taking too much levothyroxine can lead to symptoms of hyperthyroidism, including rapid heartbeat, palpitations, weight loss, and nervousness.
• Cardiovascular Issues: In some cases, excessive thyroid hormone replacement can lead to cardiovascular issues, such as an increased risk of heart disease and abnormal heart rhythms.
• Bone Health: Long-term use of levothyroxine, especially at high doses, may affect bone density, potentially increasing the risk of osteoporosis and fractures.
• Pregnancy Considerations: Pregnant women or those planning to become pregnant should consult their healthcare provider, as thyroid hormone requirements may change during pregnancy, and adjustments to the medication dosage may be necessary.
• Interactions with Other Medications: Levothyroxine can interact with other medications, affecting their absorption or effectiveness. It’s important to inform healthcare providers about all medications, supplements, and herbal products being taken.
• Allergic Reactions: While rare, some individuals may experience allergic reactions to the ingredients in Unithroid, resulting in symptoms such as rash, itching, or swelling. Seek medical attention if any signs of an allergic reaction occur.
• Adrenal Insufficiency: In some cases, levothyroxine may unmask symptoms of adrenal insufficiency, a condition where the adrenal glands do not produce enough hormones.
• Thyroid Storm (in extreme cases): Although extremely rare, an abrupt and severe increase in thyroid hormone levels can lead to a life-threatening condition known as thyroid storm. This is a medical emergency requiring immediate attention.

It’s important for individuals taking Unithroid to communicate openly with their healthcare provider, report any unusual symptoms, and attend regular follow-up appointments to monitor thyroid function and adjust medication dosage if necessary. Always take the medication as prescribed and avoid self-adjusting the dosage without consulting a healthcare professional.

Why is this medication prescribed?

Unithroid is a brand name for levothyroxine, which is a synthetic form of the thyroid hormone thyroxine (T4). It is primarily prescribed to treat hypothyroidism, a condition where the thyroid gland does not produce enough thyroid hormone. Hypothyroidism can lead to a variety of symptoms, including fatigue, weight gain, cold intolerance, dry skin, hair loss, and other issues.

Levothyroxine works by replacing or supplementing the natural thyroid hormone in the body, helping to restore normal thyroid function. It is a lifelong medication for individuals with hypothyroidism, and the dosage may need to be adjusted over time based on the patient’s response and thyroid hormone levels.

How should this medicine be used?

The use of Unituxin (dinutuximab) is typically guided by a healthcare professional, usually a pediatric oncologist, and the administration of the medication involves several steps. It’s important to note that the specific details of treatment may vary based on the individual patient’s condition, and the following information provides a general overview:

• Administration: Unituxin is administered intravenously (IV), meaning it is delivered directly into the bloodstream through a vein. The medication is usually given as part of a combination therapy for high-risk neuroblastoma.
• Pre-Medication: Before receiving Unituxin, patients may be given pre-medications to help manage potential side effects, such as allergic reactions. These pre-medications are typically administered before the Unituxin infusion.
• Treatment Schedule: The treatment schedule, including the frequency and duration of Unituxin infusions, is determined by the healthcare provider based on the specific treatment plan for the individual patient. Infusions are often given over several hours and may be repeated for several days in a row.
• Monitoring: During and after the infusion, healthcare professionals closely monitor the patient for any signs of adverse reactions or side effects. Regular monitoring and follow-up appointments are scheduled to assess the patient’s response to treatment and address any concerns.
• Supportive Care: Supportive care measures, such as managing side effects and providing medications to alleviate symptoms, may be incorporated into the overall treatment plan.
• Multidisciplinary Approach: Unituxin is typically used as part of a multidisciplinary approach to treating neuroblastoma, which may include surgery, chemotherapy, stem cell transplant, and other interventions.

Patients and their caregivers should always follow the specific instructions provided by the healthcare team. It’s essential to communicate openly with the healthcare provider about any concerns, side effects, or changes in the patient’s condition. Additionally, adherence to the prescribed treatment plan and attending scheduled follow-up appointments is crucial for the effectiveness of the therapy.

Other uses for this medicine

Levothyroxine, including the brand Unithroid, is primarily indicated for the treatment of hypothyroidism. It is not typically prescribed for other conditions unless specifically advised by a healthcare professional.

What special precautions should I follow?

Special Precautions:

• Allergies: If you are allergic to levothyroxine or any inactive ingredients in Unithroid, inform your healthcare provider.
• Heart Conditions: Individuals with heart conditions, such as heart disease or coronary artery disease, should use levothyroxine with caution, as excessive thyroid hormone can affect the cardiovascular system.
• Adrenal Insufficiency: Levothyroxine may unmask symptoms of adrenal insufficiency. If you have adrenal insufficiency or are at risk, your healthcare provider may adjust your treatment plan accordingly.
• Pregnancy and Breastfeeding: Pregnant or breastfeeding women should inform their healthcare provider, as thyroid hormone requirements may change during these periods, and adjustments to the medication dosage may be necessary.
• Drug Interactions: Inform your healthcare provider about all medications, supplements, and herbal products you are taking, as certain substances can interact with levothyroxine.
• Regular Monitoring: Regular follow-up appointments and thyroid function tests are essential to monitor the effectiveness of the treatment and adjust the dosage as needed.

Always follow your healthcare provider’s instructions, and do not self-adjust the dosage of Unithroid without consulting them. If you experience any unusual symptoms or side effects, notify your healthcare provider promptly.

What special dietary instructions should I follow?

• Consistent Diet: Maintain a consistent diet in terms of the timing and composition of meals.
• Calcium and Iron: High levels of calcium and iron in your diet or supplements may interfere with Unithroid absorption. Separate their intake by a few hours.

What should I do if I forget a dose?

• Take It As Soon As Possible: If you forget a dose, take it as soon as you remember. However, if it’s almost time for your next scheduled dose, skip the missed dose and continue with your regular dosing schedule.
• Don’t Double Up: Do not take a double dose to make up for a missed one. Taking too much levothyroxine can lead to adverse effects.
• Notify Your Doctor: If you frequently forget doses, or if you miss several doses in a row, contact your healthcare provider. They may need to adjust your dosage.

What side effects can this medication cause?

Unithroid (levothyroxine) is generally well-tolerated when taken at the prescribed dosage. However, like any medication, it can cause side effects in some individuals. Common side effects are usually mild and may include:

• Hair Loss: Some people may experience temporary hair loss, especially during the first few months of treatment.

It’s important to note that these side effects are often temporary and may subside as the body adjusts to the medication. However, if any side effects persist or become severe, it’s crucial to notify your healthcare provider.

In rare cases, an allergic reaction to Unithroid may occur. Seek immediate medical attention if you experience symptoms such as rash, itching, swelling, severe dizziness, or difficulty breathing.

It’s also important to be aware of signs of excessive thyroid hormone (hyperthyroidism), which can result from taking too much Unithroid. Symptoms may include chest pain, increased heart rate, excessive sweating, heat intolerance, and nervousness. If you experience any of these symptoms, contact your healthcare provider promptly.
