Important Compounded Semaglutide Safety Information

Compounded drugs are permitted to be prescribed under federal law but are not FDA-approved and do not undergo safety, effectiveness, or manufacturing review. Your provider may recommend certain doses of Compounded Semaglutide based on your medical evaluation.

Most Important Safety Information

  • Risk of thyroid C-Cell tumors. In studies with mice and rats, semaglutide (the active ingredient in Wegovy and Ozempic) caused thyroid C-Cell tumors, including thyroid cancer. It is not known if compounded semaglutide will cause thyroid C-Cell tumors or a type of thyroid cancer called medullary thyroid carcinoma (MTC) in people. Tell your provider if you get a lump or swelling in your neck, hoarseness, trouble swallowing, or shortness of breath. These may be symptoms of thyroid cancer.
  • Do not use compounded semaglutide if you or any of your family have ever had a type of thyroid cancer called medullary thyroid carcinoma (MTC) or if you have an endocrine system condition called Multiple Endocrine Neoplasia syndrome type 2 (MEN 2).
  • Do not use compounded semaglutide if you have had a serious allergic reaction to semaglutide or any of the ingredients in compounded semaglutide injections.

What is compounded semaglutide used for?

Compounded semaglutide is a glucagon-like peptide-1 (GLP-1) receptor agonist for chronic weight management, along with a reduced calorie diet and increased physical activity, for adults with an initial body mass index (BMI) of:

  • 30 kg/m2 or greater (obesity) or
  • 27 kg/m2 or greater (overweight) in the presence of at least one weight-related comorbid condition (e.g., hypertension, type 2 diabetes mellitus, or dyslipidemia).

Limitations of Use:

  • Semaglutide should not be used in combination with other semaglutide-containing products or any other GLP-1 receptor agonist
  • The safety and efficacy of coadministration with other products for weight loss have not been established
  • Semaglutide has not been studied in patients with a history of pancreatitis
  • Semaglutide should not be used in patients with type 1 diabetes mellitus

What should I tell my provider before using semaglutide?

Drugs you are taking. It’s important to tell your provider all of the medications you are currently taking, including prescription, over-the-counter medications, vitamins, and herbal and dietary supplements.

Your entire medical history. In particular, tell your provider if you have a past history of:

  • Type 1 or type 2 diabetes
  • Medullary thyroid carcinoma (MTC) or Multiple Endocrine Neoplasia syndrome type 2 (MEN 2)
  • Pancreatitis
  • Gallbladder issues
  • Severe problems with your stomach, including gastroparesis or problems digesting food
  • Kidney disease
  • Diabetic retinopathy
  • History of Eating Disorders
  • Depression
  • Suicidal thoughts or behavior, or other mental health issues.
  • History of a suicide attempt

Whether you are pregnant, planning to become pregnant, or breastfeeding.

  • If you are pregnant: Semaglutide should not be used during pregnancy. Based on animal studies, there may be potential risks to an unborn baby from exposure to semaglutide during pregnancy. There is no benefit to weight loss during pregnancy and it may cause harm to the unborn baby.
  • If you are a female or male of reproductive potential: Discontinue semaglutide at least 2 months before a planned pregnancy since the drug can stay in the bloodstream for a long time.
  • If you are breastfeeding: Semaglutide was found in the milk of lactating rats. Tell your provider if you are breastfeeding before you start taking semaglutide.

Withholding or providing inaccurate information about your health and medical history in order to obtain treatment may result in harm, including, in some cases, death.

What drug interactions do I need to be aware of?

Some medications to watch out for include:

  • Insulin
  • Sulfonylureas (these can cause blood sugar levels to drop dangerously low when combined with compounded semaglutide)
  • Compounded semaglutide causes a delay in gastric emptying, so it has the potential to impact the absorption of medications that are taken by mouth at the same time. Your provider can guide you on how to schedule your medications.
  • Other GLP-1 or GLP-1/GIP receptor agonist medications such as liraglutide, dulaglutide, or tirzepatide
  • Other products for weight loss, including dietary supplements

What are the most serious side effects that I or a caregiver should monitor for when taking semaglutide?

If you are experiencing a medical emergency, call 911 or seek immediate medical attention.

These serious side effects can occur with semaglutide. You or a caregiver should carefully monitor for these side effects, especially in the beginning of treatment and with dose changes.

  • Thyroid C-Cell Tumors: In mice and rats, semaglutide caused an increase in thyroid C-cell tumors, including medullary thyroid carcinoma (MTC). It is unknown whether semaglutide causes thyroid C-cell tumors in humans. There were cases of MTC reported in patients who took liraglutide (the active ingredient in Victoza and Saxenda) after the drug was put on the market. Semaglutide is contraindicated in patients with a family history of MTC or in patients with Multiple Endocrine Neoplasia syndrome type 2 (MEN 2). Tell your provider if you get a lump or swelling in your neck, hoarseness, trouble swallowing, or shortness of breath. These may be symptoms of thyroid cancer.
  • Inflammation of Pancreas (Acute Pancreatitis): Monitor for signs of acute pancreatitis, including severe abdominal pain that does not go away, sometimes radiating to the back, with or without vomiting.
  • Acute Gallbladder Disease: Semaglutide may cause gallbladder problems, including gallstones. Some gallbladder problems require surgery. Tell your provider right away if you have pain in your upper stomach, yellowing of skin or eyes (jaundice), fever, or clay-colored stools.
  • Low Blood Sugar (hypoglycemia): Semaglutide lowers blood glucose. It can cause too low blood sugar in patients with type 2 diabetes who also take another glucose control medication. Monitor your blood sugar and watch out for signs of too low blood sugar such as dizziness, blurred vision, mood changes, sweating, or fast heartbeat.
  • Acute Kidney Injury: In people who have kidney problems, diarrhea, nausea, and vomiting may cause a loss of fluids (dehydration) which may cause kidney problems to get worse. It is important for you to drink plenty of water to help reduce your chance of dehydration.
  • Serious Allergic Reactions: Stop using semaglutide right away if you experience symptoms of a serious allergic reaction, including swelling of your face, lips, tongue or throat, severe rash or itching, very rapid heartbeat, problems breathing or swallowing, or fainting or feeling dizzy.
  • Diabetic Retinopathy Complications in Patients with Type 2 Diabetes: If you have type 2 diabetes, tell your provider right away if you experience changes in vision.
  • Increase in Heart Rate: Tell your provider right away if you have a racing heartbeat while at rest.
  • Suicidal Behavior and Ideation: You should pay attention to any mental health changes, especially sudden changes in your mood, behaviors, thoughts, or feelings. Call your healthcare provider right away if you have any mental changes that are new, worse, or worry you.
  • Never Share a Needle: Needle-sharing poses a risk of infection.

These common side effects can occur with semaglutide.

  • Nausea
  • Diarrhea
  • Vomiting
  • Constipation

  • Headache
  • Fatigue
