Levothyroxine BNF, commonly known as levothyroxine, is a medication that is commonly prescribed for the treatment of an underactive thyroid gland, also known as hypothyroidism. This condition occurs when the thyroid gland is not able to produce enough thyroid hormone, which is essential for the proper functioning of various bodily processes.
Levothyroxine BNF works by replacing or supplementing the thyroid hormone in the body, helping to restore the normal levels of thyroid hormone. It is available in tablet form and is typically taken once a day, preferably on an empty stomach. The dosage of levothyroxine BNF prescribed may vary depending on the individual's age, weight, and the severity of their hypothyroidism.
While levothyroxine BNF is generally considered to be safe and effective, there are some potential side effects that individuals may experience. These can include changes in appetite, weight fluctuations, difficulty sleeping, and increased heart rate. It is important to discuss any concerns or potential side effects with a healthcare provider.
In addition to treating hypothyroidism, levothyroxine BNF is also sometimes prescribed to individuals who have had their thyroid gland removed due to thyroid cancer or other conditions. It may also be prescribed to individuals who have an enlarged thyroid gland, known as a goiter.
In conclusion, levothyroxine BNF is a medication commonly used to treat hypothyroidism and other thyroid-related conditions. It works by supplementing the thyroid hormone in the body and restoring normal thyroid hormone levels. While it is generally well-tolerated, individuals should be aware of potential side effects and consult with their healthcare provider if they have any concerns.
What is Levothyroxine BNF?
Levothyroxine BNF, also known as levothyroxine sodium, is a medication that is used to treat an underactive thyroid gland. It works by replacing or providing the thyroid hormone that is normally produced by the thyroid gland. Levothyroxine BNF comes in tablet form and is available in various strengths. It is a prescription medication that should only be taken under the supervision of a healthcare professional.
How does Levothyroxine BNF work?
Levothyroxine BNF works by increasing the levels of thyroid hormone in the body. The thyroid hormone, called thyroxine, is essential for regulating the body's metabolism. When the thyroid gland is not producing enough thyroxine, it can lead to symptoms such as fatigue, weight gain, and sluggishness. Levothyroxine BNF helps to restore the levels of thyroxine in the body, which can alleviate these symptoms and improve overall well-being.
Uses of Levothyroxine BNF
- Treating hypothyroidism: Levothyroxine BNF is commonly used to treat hypothyroidism, a condition in which the thyroid gland does not produce enough thyroid hormone.
- Managing goiter: Levothyroxine BNF may be used to help shrink an enlarged thyroid gland, also known as a goiter.
- Preventing thyroid cancer recurrence: In some cases, levothyroxine BNF is prescribed to prevent the recurrence of thyroid cancer after surgery or other treatments.
Dosage of Levothyroxine BNF
The dosage of levothyroxine BNF will vary depending on the individual's specific needs, including factors such as age, weight, and the severity of the thyroid condition being treated. It is important to follow the dosage instructions provided by a healthcare professional and to take the medication as directed. Adjustments to the dosage may be made over time to ensure optimal effectiveness.
Possible Side Effects of Levothyroxine BNF
While levothyroxine BNF is generally well-tolerated, there are some potential side effects that may occur. These can include symptoms such as headache, nervousness, increased appetite, and weight loss. It is important to notify a healthcare professional if any side effects occur or if there are any concerns about the medication.
Uses of Levothyroxine BNF
Levothyroxine BNF, a synthetic form of the thyroid hormone thyroxine, is commonly used to treat hypothyroidism. Hypothyroidism is a condition in which the thyroid gland does not produce enough thyroid hormone, leading to symptoms such as fatigue, weight gain, and depression. Levothyroxine BNF helps to increase the levels of thyroid hormone in the body, restoring normal thyroid function and alleviating these symptoms.
In addition to treating hypothyroidism, levothyroxine BNF is also used in the management of certain types of thyroid cancer. It is often prescribed as part of a combination therapy, along with other medications or treatments, to help reduce the size of the tumor and prevent its spread to other parts of the body.
Levothyroxine BNF is also sometimes used off-label to aid in weight loss. The medication can help to boost metabolism and increase energy levels, which may result in some individuals experiencing weight loss. However, it should be noted that levothyroxine BNF should not be used solely for the purpose of weight loss, and should only be taken under the guidance of a healthcare professional.
In some cases, levothyroxine BNF may be prescribed to individuals with subclinical hypothyroidism, a condition in which the thyroid hormone levels are slightly lower than normal but do not meet the criteria for a diagnosis of hypothyroidism. This treatment approach is still a subject of debate and further research is needed to determine its effectiveness.
Overall, levothyroxine BNF is a vital medication used to treat hypothyroidism and manage certain types of thyroid cancer. It plays a crucial role in restoring thyroid function and alleviating associated symptoms, improving the quality of life for individuals with these conditions.
Dosage of Levothyroxine BNF
Levothyroxine BNF is a medication used to treat an underactive thyroid gland, also known as hypothyroidism. The dosage of Levothyroxine BNF can vary depending on the individual and their specific condition.
The recommended starting dose for adults with hypothyroidism is usually 50-100 micrograms once daily. However, the dosage may need to be adjusted based on factors such as age, weight, severity of the condition, and other medications being taken.
In some cases, the dosage may need to be gradually increased over time to achieve optimal thyroid hormone levels and alleviate symptoms of hypothyroidism. It is important to follow the dosage instructions provided by a healthcare professional and not to adjust the dosage without their guidance.
For children with hypothyroidism, the dosage of Levothyroxine BNF is usually based on their body weight and age. A pediatric endocrinologist will determine the appropriate dosage for each child, taking into account their growth and development needs. Regular monitoring is necessary to ensure the dosage remains effective.
If a dose of Levothyroxine BNF is missed, it should be taken as soon as possible. However, if it is almost time for the next dose, the missed dose should be skipped and the regular dosing schedule resumed. Double doses should not be taken to make up for a missed dose.
It is important to regularly consult with a healthcare professional to evaluate the effectiveness of the dosage and make any necessary adjustments. Individuals should also be aware of any potential side effects and report them to their healthcare provider.

If any of these side effects are bothersome or worsen over time, it is important to discuss them with a healthcare provider. They can provide guidance and make any necessary adjustments to the treatment regimen if needed.
Precautions for Levothyroxine BNF
When taking Levothyroxine BNF, it is important to follow certain precautions to ensure its safe and effective use. Here are some key precautions to keep in mind:
- Medical history: Before starting Levothyroxine BNF, inform your healthcare provider about any past or current medical conditions, especially if you have heart disease, diabetes, adrenal gland problems, or a history of thyroid disorders.

By following these precautions and working closely with your healthcare provider, you can safely and effectively use Levothyroxine BNF for the management of thyroid disorders.
Interactions with Other Medications
Taking levothyroxine can potentially interact with other medications, leading to less effectiveness or increased side effects. It is important to inform your healthcare provider about all the medications you are currently taking to avoid any potential negative interactions.
Certain medications can interfere with the absorption of levothyroxine, such as calcium supplements, iron supplements, and antacids. These medications should be taken at least four hours apart from levothyroxine to ensure proper absorption.
Some medications may increase the metabolism of levothyroxine, leading to a decrease in its effectiveness. Examples include rifampicin used to treat tuberculosis and anti-seizure medications such as carbamazepine and phenytoin. Your healthcare provider may need to adjust the dosage of levothyroxine if you are taking any of these medications.
Certain medications can also increase the risk of side effects when taken with levothyroxine. For example, taking levothyroxine with medications that increase heart rate, such as beta-blockers, may increase the risk of heart-related side effects. It is important to monitor your heart rate and blood pressure regularly if you are taking both medications.
Additionally, some medications can affect the levels of thyroid hormones in your body, which may require adjustments in the dosage of levothyroxine. Examples include medications that affect liver function, such as amiodarone used to treat heart rhythm problems, and certain antidepressants.
To ensure the safe and effective use of levothyroxine, it is essential to communicate with your healthcare provider about all the medications you are taking. They can provide personalized guidance and monitor your progress to prevent any potential interactions or complications.
Levothyroxine BNF and Pregnancy
When it comes to pregnancy, it is important to consider the use of Levothyroxine BNF with caution. Levothyroxine is a synthetic form of thyroid hormone that is commonly prescribed to treat hypothyroidism. During pregnancy, the need for thyroid hormone increases, and many women with hypothyroidism require an adjustment in their medication doses.
Levothyroxine BNF is generally considered safe for use during pregnancy. It is important, however, for pregnant women to work closely with their healthcare providers to monitor their thyroid levels and adjust their medication dosage as needed. This is because inadequately controlled hypothyroidism during pregnancy can have negative effects on both the mother and the fetus.
It is worth noting that the dosage of Levothyroxine BNF may need to be increased during pregnancy due to the physiological changes that occur. Pregnant women should not make any changes to their medication regimen without consulting their healthcare provider. Regular monitoring of thyroid function is recommended throughout pregnancy to ensure optimal control.
In some cases, women who are planning to become pregnant may need to start taking Levothyroxine BNF before conception to ensure that their thyroid levels are adequately controlled. It is important to discuss any plans for pregnancy with a healthcare provider so that appropriate measures can be taken to optimize thyroid function.
In conclusion, the use of Levothyroxine BNF during pregnancy requires careful monitoring and adjustment of medication dosage. Pregnant women should work closely with their healthcare providers to ensure that their thyroid levels are adequately controlled for the health and well-being of both themselves and their baby.
Levothyroxine BNF and Breastfeeding
Levothyroxine BNF is a medication commonly prescribed for treating an underactive thyroid gland. However, it is important to consider its use and potential effects when breastfeeding.
While levothyroxine is considered safe to use during breastfeeding, it is important to consult with a healthcare professional for personalized advice. The dosage of levothyroxine may need to be adjusted during this period to ensure the optimal thyroid function for both the mother and the baby.
Symptoms of an underactive thyroid, such as fatigue, weight gain, and depression, can have an impact on breastfeeding. It is essential for new mothers to receive the necessary treatment to ensure their thyroid function is regulated, enabling them to continue breastfeeding without interruptions.
Monitoring thyroid hormone levels is crucial during breastfeeding. Regular blood tests can help healthcare professionals determine the appropriate dosage of levothyroxine needed to maintain optimal thyroid levels. It is important to follow the advice provided by healthcare professionals and to inform them of any changes or concerns.
In conclusion, levothyroxine BNF can be used safely during breastfeeding, but it is important to seek guidance from healthcare professionals to ensure the correct dosage and monitoring of thyroid hormone levels. This will help new mothers maintain their thyroid function and continue providing breast milk for their baby.
