Ozempic

Primary Uses

Ozempic is approved by the FDA for two main purposes in adults with type 2 diabetes mellitus:

• Blood Sugar Management: It is used in combination with diet and exercise to improve glycemic control (blood sugar levels).
• Cardiovascular Risk Reduction: It is used to reduce the risk of major adverse cardiovascular events, such as heart attack, stroke, or death, in adults who have both type 2 diabetes and established heart disease.

Usage Limitations

Ozempic is not used to treat type 1 diabetes or diabetic ketoacidosis. It has not been studied in people who have had pancreatitis in the past. While the active ingredient in Ozempic may lead to weight loss, this specific medication is not FDA-approved as a weight-loss drug.

Healthcare providers typically prescribe Ozempic when other medications have not sufficiently controlled blood sugar levels or when a patient is at high risk for heart-related complications. It is meant to be part of a comprehensive treatment plan that includes nutritional changes and physical activity.

Mechanism of Action

Ozempic belongs to a class of medications known as glucagon-like peptide-1 (GLP-1) receptor agonists. It functions by acting like the GLP-1 hormone that the body naturally produces in the intestines after eating.

Blood Sugar Regulation

The medication helps manage blood sugar in two primary ways:

• Insulin secretion: It stimulates the pancreas to release insulin when blood sugar levels are high. Insulin is necessary to move sugar from the bloodstream into the cells for energy.
• Glucagon reduction: It lowers the amount of glucagon the liver produces, which prevents excess sugar from being released into the bloodstream.

Digestion and Satiety

Ozempic also affects how the body processes food. It slows down gastric emptying, which is the speed at which food leaves the stomach and enters the small intestine. By slowing this process, the medication helps prevent blood sugar spikes after meals and contributes to a feeling of fullness for a longer period.

Common Side Effects

The most frequent side effects of Ozempic involve the digestive system. These symptoms are often most noticeable when starting the medication or when the dose is increased. Common side effects include:

• Nausea and vomiting
• Diarrhea or constipation
• Stomach pain and bloating
• Heartburn or gas
• Burping

Serious Side Effects

Some side effects can be severe and require prompt medical evaluation. These include:

• Pancreatitis: Inflammation of the pancreas can cause severe pain in the upper stomach area that may reach the back.
• Vision Changes: People with type 2 diabetes may experience changes in vision or worsening of diabetic retinopathy.
• Kidney Problems: Severe nausea and diarrhea can lead to dehydration, which may cause kidney injury or failure.
• Gallbladder Problems: This may include gallstones or inflammation, often marked by upper stomach pain and fever.
• Low Blood Sugar (Hypoglycemia): The risk of low blood sugar increases if Ozempic is taken with other medications like insulin or sulfonylureas.
• Allergic Reactions: Severe reactions can cause swelling of the face or throat, rash, and difficulty breathing.

Redness, itching, or discomfort at the site of the injection may also occur.

Boxed Warning: Thyroid C-cell Tumors

In animal studies, semaglutide (the active ingredient in Ozempic) caused thyroid tumors. It is unknown if this occurs in humans. This medication is contraindicated in individuals with a personal or family history of medullary thyroid carcinoma (MTC) or Multiple Endocrine Neoplasia syndrome type 2 (MEN 2).

Serious Precautions

Pancreatitis

Inflammation of the pancreas (pancreatitis) has been reported. Symptoms include severe pain in the upper stomach area that may spread to the back, with or without vomiting. The medication should be discontinued if pancreatitis is suspected.

Diabetic Retinopathy

Rapid improvements in blood sugar control may lead to a temporary worsening of diabetic retinopathy (damage to the blood vessels in the eyes). Patients with a history of this condition should be monitored for vision changes.

Kidney Injury

Severe gastrointestinal reactions, such as nausea, vomiting, and diarrhea, can lead to dehydration. This dehydration may cause or worsen kidney problems, including acute kidney injury or failure. Monitoring kidney function is often necessary for those experiencing severe stomach issues.

Hypoglycemia

The risk of low blood sugar (hypoglycemia) increases when Ozempic is used with other diabetes medications, such as insulin or sulfonylureas. Healthcare providers may need to adjust the dosages of these other medications to reduce this risk.

Gallbladder Problems

Ozempic may cause gallbladder issues, including gallstones (cholelithiasis) or inflammation of the gallbladder (cholecystitis). Symptoms may include upper stomach pain, fever, or yellowing of the skin and eyes.

Allergic Reactions

Serious allergic reactions, including anaphylaxis and angioedema, have occurred. Symptoms may include swelling of the face, lips, or tongue, difficulty breathing, or severe rash.

Pregnancy and Planning

Ozempic may cause fetal harm. Because the medication stays in the system for a long time, it is generally recommended to stop using it at least two months before a planned pregnancy.

Pregnancy

Data on the use of Ozempic in pregnant individuals is limited. Animal studies have indicated that the medication may cause fetal harm, including pregnancy loss and structural abnormalities. Consequently, healthcare providers typically advise against using this medication during pregnancy.

Because Ozempic has a long half-life and stays in the system for several weeks, it is recommended to discontinue the medication at least two months before a planned pregnancy to ensure it has cleared the body.

Breastfeeding

It is currently unknown if Ozempic passes into human breast milk. In animal studies, the medication was present in the milk of lactating animals. Because the potential risks to a nursing infant are not fully understood, individuals should discuss the benefits and risks with a healthcare professional before breastfeeding while using this medication.

Available Forms

Ozempic is supplied as a clear, colorless solution for injection. It is provided in a pre-filled, disposable delivery device, commonly referred to as a pen.

Administration Method

• Subcutaneous Injection: The medication is injected into the fat layer just under the skin, typically in the abdomen, thigh, or upper arm.
• Multi-dose Pens: Each pen is designed to deliver multiple doses of the medication. A new needle must be attached for each individual injection.

The medication is intended for single-patient use only. Sharing pens or needles between patients is not safe, even if the needle is changed.

FDA Approval and Indications

Ozempic (semaglutide) is FDA-approved as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus. It is also indicated to reduce the risk of major adverse cardiovascular events, such as heart attack, stroke, or death, in adults with type 2 diabetes and established cardiovascular disease.

Boxed Warning

Ozempic carries a boxed warning regarding the risk of thyroid C-cell tumors. In rodent studies, semaglutide caused dose-dependent and treatment-duration-dependent thyroid tumors. It is not yet known if Ozempic causes thyroid C-cell tumors, including medullary thyroid carcinoma (MTC), in humans. The medication is contraindicated in patients with a personal or family history of MTC or in patients with Multiple Endocrine Neoplasia syndrome type 2 (MEN 2).

Regulatory Safety Communications

The FDA has issued communications regarding the following regulatory concerns:

• Unapproved and Compounded Drugs: The FDA has expressed concerns about the use of unapproved compounded versions of semaglutide. These products may contain salt forms, such as semaglutide sodium or semaglutide acetate, which have not been shown to be safe or effective.
• Counterfeit Products: There have been reports of counterfeit Ozempic pens entering the U.S. drug supply chain. The FDA advises patients to only obtain Ozempic through state-licensed pharmacies.
• Marketing Compliance: The FDA has issued warning letters to manufacturers regarding promotional materials that were found to be misleading, specifically for failing to provide adequate risk information or for making unsubstantiated claims about the drug's benefits.

How Ozempic Affects Weight

Ozempic mimics a naturally occurring hormone called glucagon-like peptide-1 (GLP-1). This hormone helps regulate appetite by signaling the brain to feel full and by slowing the movement of food through the digestive tract. These effects often lead to reduced calorie intake and subsequent weight loss.

FDA Approval and Off-Label Use

Ozempic is FDA-approved to improve blood sugar levels in adults with type 2 diabetes and to reduce the risk of heart attack or stroke in people with both type 2 diabetes and heart disease. It is not FDA-approved as a weight-loss medication. However, because semaglutide can lead to weight reduction, some healthcare providers prescribe it off-label for weight management.

Safety and Precautions

The FDA has issued warnings regarding the use of unapproved or compounded versions of semaglutide marketed for weight loss. Patients are advised to obtain the medication only through a licensed healthcare provider and a legitimate pharmacy. For weight management, the medication is most effective when used alongside a reduced-calorie diet and regular physical activity.

• Weight loss is a common side effect observed in clinical trials for diabetes treatment.
• The medication is typically administered as a once-weekly subcutaneous injection.
• Long-term weight management requires consistent lifestyle changes in addition to medication.
