What Is Semaglutide?
Semaglutide is a type of medication that belongs to the glucagon-like peptide-1 (GLP-1) receptor agonist class of drugs. It is mainly prescribed for adults who have type 2 diabetes and struggle to maintain blood sugar levels through diet, exercise, and other medications. There are three different brand-name versions of semaglutide available: Wegovy, Ozempic, and Rybelsus.
This medication works by mimicking the action of a naturally occurring hormone called GLP-1, which increases the release of insulin and decreases the release of glucagon. This combination helps to lower blood sugar levels in a safe and controlled manner. In addition to controlling blood sugar levels, semaglutide can also promote weight loss and lower the risk of major cardiovascular events, such as heart attacks and strokes. It is important to mention that the drug may increase the risk of developing tumors in the thyroid gland, including medullary thyroid carcinoma (MTC), although this risk is still not fully understood in humans according to MedlinePlus.
Semaglutide is available as a once-weekly injection (Ozempic) or in an oral form (Rybelsus) taken once daily. The appropriate dosage and form of administration depend on the individual’s specific needs and medical history, as determined by a healthcare provider. Some common side effects may include gastrointestinal effects, such as nausea, vomiting, and diarrhea, as well as headache and increased heart rate.
In the context of hypothyroidism, semaglutide has shown promise as a potential treatment option. Some studies suggest that it offers benefits like improved thyroid function, weight loss, and cardiovascular health for individuals struggling with this condition. However, as with any medication, it is crucial to consult with a medical professional to determine if semaglutide is the right choice for managing both diabetes and hypothyroidism.
Can Semaglutide Affect Thyroid Function?
Semaglutide is a glucagon-like-peptide-1 (GLP-1) receptor agonist that is primarily used to treat type 2 diabetes and aid in weight loss. It helps lower blood sugar levels and decreases appetite, thereby promoting weight loss. However, there is ongoing research to determine its effects on thyroid function, especially in individuals with hypothyroidism.
According to a study, the association between GLP-1 receptor agonists, such as semaglutide, and various thyroid disorders is still uncertain. This means that not enough conclusive evidence is available regarding the potential impact of semaglutide on thyroid function. Nonetheless, it is worth noting that other GLP-1 receptor agonists have been associated with a low risk of thyroid disorders.
People with hypothyroidism who are considering using semaglutide for weight loss should consult their physician or an endocrinologist. There is some evidence to suggest that semaglutide may help with weight loss in individuals with hypothyroidism, but it is essential to carefully manage thyroid function throughout treatment. Additional factors, such as proper thyroid medication dosage and adherence to a healthy lifestyle plan, will also influence weight loss success.
In conclusion, while research continues to explore the potential relationship between semaglutide and thyroid function, individuals with hypothyroidism should discuss the benefits and risks of using semaglutide with their healthcare provider.
Thyroid-Related Complications
Semaglutide, a glucagon-like peptide-1 (GLP-1) receptor agonist, has gained attention for its potential use in weight management for individuals with hypothyroidism. However, there are concerns regarding its safety and possible thyroid-related complications.
One of the primary concerns with semaglutide is its association with thyroid cancer, specifically medullary thyroid carcinoma (MTC). MTC is a rare type of thyroid cancer that originates from the C-cells in the thyroid gland. These cells produce calcitonin, a hormone involved in the regulation of calcium levels in the body. In some rodent studies, semaglutide has been linked to an increased risk of thyroid C-cell tumors1. However, it is crucial to note that the relevance of these findings to humans remains uncertain.
Another type of thyroid cancer potentially linked to semaglutide is papillary thyroid cancer. This form of cancer is more common and originates from thyroid follicular cells. To date, there is limited evidence to suggest a direct connection between semaglutide and the development of papillary thyroid cancer.
Additionally, there is a potential risk of thyroid hyperplasia in patients who take semaglutide. Thyroid hyperplasia refers to an abnormal increase in the number of cells within the thyroid gland, which can cause thyroid enlargement and potentially lead to hypothyroidism. However, it is important to mention that available research on the association between semaglutide and thyroid hyperplasia is inconclusive.
Other thyroid-related concerns related to semaglutide use include multiple endocrine neoplasia (MEN), a group of inherited disorders that cause tumors in the endocrine glands. Semaglutide is contraindicated in patients with a personal or family history of MTC or in those with MEN2.
In conclusion, while there are some concerns regarding semaglutide’s link with thyroid-related complications such as thyroid cancer and hyperplasia, more research is needed to determine the significance of these findings in humans. Patients should consult their healthcare provider to discuss the potential risks and benefits of using semaglutide in managing hypothyroidism.

Hypothyroidism and Semaglutide
Can semaglutide be taken with levothyroxine?
Hypothyroidism is a condition where the thyroid gland does not produce enough thyroid hormone, leading to various symptoms such as fatigue, weight gain, and sensitivity to cold. Levothyroxine, a synthetic form of the thyroid hormone thyroxine, is commonly prescribed to treat hypothyroidism and normalize thyroid-stimulating hormone (TSH) levels. Semaglutide, a glucagon-like peptide-1 (GLP-1) receptor agonist, is primarily prescribed for weight loss in patients with type 2 diabetes.
An open-label, one-sequence crossover, single-center, multiple-dose, two-part trial investigated the effect of oral semaglutide on the pharmacokinetics of thyroxine after dosing of levothyroxine in healthy subjects. Although the study did not specifically focus on hypothyroid patients, it may provide some insight into possible interactions between semaglutide and levothyroxine. More research is needed to understand how these two medications impact each other in patients with hypothyroidism.
Do thyroid nodules impact semaglutide efficacy?
Thyroid nodules are growths in the thyroid gland that can be malignant or benign. While some nodules can produce excess thyroid hormone, leading to hyperthyroidism, others may not have a direct impact on thyroid function. In the context of hypothyroidism and semaglutide, it’s essential to understand if the presence of thyroid nodules affects the efficacy of semaglutide.
A study conducted on GLP-1 receptor agonists, including semaglutide, analyzed the occurrence of thyroid disorders, but it did not specifically focus on thyroid nodules. The results showed that the pooled risk ratio (RR) of overall thyroid disorders in patients receiving semaglutide versus other interventions was 0.75 (95% CI 0.35‐1.57). However, it’s unclear if the presence of thyroid nodules affects the efficacy of semaglutide in treating symptoms of hypothyroidism or weight loss.
Further research is required to understand the implications of thyroid nodules on the efficacy of semaglutide in patients with hypothyroidism. It’s important to consult a healthcare professional when considering the use of semaglutide alongside thyroid medications to manage hypothyroid symptoms and weight loss.
Oral vs. Subcutaneous Semaglutide
Semaglutide is a glucagon-like peptide-1 (GLP-1) receptor agonist commonly used to treat type 2 diabetes. It is available in two different formulations: oral semaglutide (marketed as Rybelsus) and subcutaneous semaglutide (administered as an injection). Both forms effectively improve glycemic control and assist in weight loss, but they differ in the methods by which they are administered and their relative efficacy.
Oral semaglutide has the advantage of being more convenient for patients, as it is taken in tablet form. This allows for a simpler treatment regimen compared to injections, which can be more time-consuming and require patients to learn proper injection techniques. The efficacy of oral semaglutide is similar to that of some other GLP-1 receptor agonists; it has been observed to decrease body weight more than sitagliptin and liraglutide, with comparable reductions to empagliflozin.
Subcutaneous semaglutide, on the other hand, tends to demonstrate greater efficacy in reducing glycated hemoglobin and body weight compared to other GLP-1 receptor agonists. This formulation has also shown benefits in reducing major adverse cardiovascular events in patients with type 2 diabetes. However, the injection form may pose challenges for certain patient populations, such as those with hepatic or renal impairment.
Both oral and subcutaneous semaglutide have potential safety concerns, which should be taken into consideration when selecting the appropriate treatment options. It is important for healthcare providers to assess each patient’s individual needs and preferences to determine the most suitable form of semaglutide for their circumstances.
Although there is no direct evidence linking semaglutide to hypothyroidism, it is important for patients and healthcare providers to be aware of any potential risks or interactions with other medications. Close monitoring and regular follow-ups are essential in ensuring optimal treatment and the well-being of individuals receiving semaglutide therapy.
Semaglutide: Dosage and Administration
Semaglutide is available in two forms: as an injectable medication (brand names Ozempic) and an oral tablet (brand name Rybelsus). The injectable form of semaglutide is primarily used to manage blood sugar levels in adults with type 2 diabetes, whereas the oral tablet form has the same purpose but can also be used for weight loss in specific patients.
The recommended dosage for oral semaglutide tablets is an initial dose of 3 mg once daily for 30 days, followed by an increase to 7 mg once daily. If additional glycemic control is needed after receiving the 7 mg/day dose for at least 30 days, the dosage may be increased to a maximum of 14 mg per day. On the other hand, the injectable form, Ozempic, is administered once every 7 days. It is important to follow the prescribing healthcare provider’s directions for the specific form and dosage of semaglutide being taken.
In terms of administration, the injectable semaglutide is meant for subcutaneous injection in the upper leg (thigh), stomach area, or upper arm. Patients will be taught how to prepare and inject the medication by a healthcare professional. To ensure consistency, the injections should be given at regular intervals.
For the oral semaglutide tablets, they should be taken whole and not crushed or split. It is crucial to take the medication at the same time each day, with or without food, to maintain steady blood sugar levels and increase the effectiveness of the treatment.
It is essential to monitor and adjust the dosage according to the patient’s response and specific needs. If side effects or complications arise, it may be necessary to change the dosage or discontinue the medication.

Conclusions
In the context of semaglutide and hypothyroidism, it is important to consider the various findings and evidence regarding their potential interaction. Research has shown that GLP-1 receptor agonists, which include semaglutide, do not significantly increase or decrease the risk of thyroid-related conditions, including thyroid cancer, hyperthyroidism, hypothyroidism, thyroiditis, thyroid mass, and goiter1. However, it is also noteworthy that these findings need further examination due to the low incidence of these diseases.
Oral semaglutide has been studied specifically for its potential impact on levothyroxine pharmacokinetics2. This is of particular interest since levothyroxine is a common medication prescribed for hypothyroidism. The trial investigated if oral semaglutide co-administered with levothyroxine affects thyroxine (T4) exposure and if multiple placebo tablets co-administered with oral semaglutide affect semaglutide exposure.
A case report has suggested that an influence of subcutaneous semaglutide on thyroid function is possible, highlighting the need for thyroid function tests in patients receiving both levothyroxine and semaglutide3. Nevertheless, this is just a single case report, and further research is needed to confirm any potential interaction between semaglutide and hypothyroidism.
Regarding the safety profile of semaglutide, studies have not identified any unexpected safety issues to date4. Moreover, its safety profile is comparable to that of other GLP-1RAs, with definitive conclusions for pancreatic and thyroid cancer remaining elusive due to the low occurrence of these conditions.
In sum, while semaglutide and hypothyroidism have been studied to an extent, further research is necessary to establish their potential interaction more definitively. Until then, caution and close monitoring of thyroid function may be advised for patients taking semaglutide and levothyroxine concurrently.
