What is Ozempic

Ozempic Overview

Ozempic (semaglutide) is a prescription medication in the GLP-1 receptor agonist drug class. First approved by the U.S. Food and Drug Administration (FDA) in 2017, Ozempic is given as a weekly injection given subcutaneously, or under the skin. Ozempic has benefits in managing type 2 diabetes and reducing the risk of heart attacks, strokes, and chronic kidney disease progression. Unlike Wegovy, which is for weight loss and contains the same active ingredient, semaglutide, Ozempic is only approved for diabetes and cardiovascular risks.

How Ozempic Works

Ozempic contains semaglutide, which acts as a GLP-1 agonist. It mimics the GLP-1 hormone by attaching to GLP-1 receptors, typically found in the gut, though they can also be found in the brain and other parts of the body. GLP-1 is a natural hormone that’s released after eating a meal to increase insulin. 

Ozempic helps regulate blood sugar levels by ultimately increasing insulin, another hormone that transports sugar (glucose) into the body’s cells for energy. It also decreases the release of yet another hormone called glucagon to lower the production of glucose in the liver. These effects help the body use the sugar it already has while reducing any unnecessary sugar release into the blood.

Ozempic also slows the emptying of the stomach, which can lead to an increased feeling of fullness and decreased caloric intake. As a result, individuals may be less likely to eat excessively. That’s why Ozempic is widely known for promoting weight loss. In addition, it may have direct effects in certain brain areas to reduce appetite. 

Lower blood sugar levels can trigger other benefits in the body, including reduced inflammation. Improved glucose levels help decrease stress on the walls of the blood vessels to manage cardiovascular risks. Better glucose control also helps reduce the workload on the kidneys, as they no longer have to work to filter out excess glucose.

FDA-Approved Uses and Indications

Ozempic is approved by the FDA for different uses. A doctor or healthcare provider may prescribe Ozempic for the following:

• Type 2 diabetes in adults, when used alongside a diet and exercise plan
• Reducing the risk of heart attacks, strokes, and heart-related deaths in adults with type 2 diabetes and heart disease
• Preventing kidney failure, slowing kidney disease progression, and reducing the risk of heart-related deaths in adults with type 2 diabetes and chronic kidney disease

Ozempic is sometimes used off-label for other purposes, especially weight management. However, using Ozempic off-label means using it for an indication that hasn’t been approved by the FDA. However, healthcare providers may still prescribe Ozempic for weight loss based on their clinical experience and the supporting data from studies. 

The active ingredient of Ozempic can be found under a different brand name, Wegovy, which is approved for weight management. The difference between the two lies in their dosing schedules, but side effects and safety precautions are the same.  

Ozempic Dosing Schedules

It is very important to know that these guidelines are for general information, and individual guidelines from your doctor will be prescribed for you to follow.

Ozempic is usually taken as a subcutaneous injection once weekly. It should ideally be taken on the same day each week. There are no specific requirements for food or time of day, meaning it can be taken at any time of day, with or without a meal. 

When first starting Ozempic, there’s a specific dosing schedule to follow to ensure it’s effective without causing serious side effects.

The first dosage is as follows:

• 0.25 mg injected once weekly for 4 weeks
• After 4 weeks on the 0.25 mg dose, the dosage is increased to 0.5 mg once weekly

The dosage can then be increased in 4-week intervals until a maintenance dose is reached. The maintenance dose will depend on the condition being treated and how a person responds to the treatment.

The recommended maintenance dose of Ozempic is as follows:

• Type 2 diabetes: 0.5 mg, 1 mg, or 2 mg once weekly, based on blood sugar levels 
• Chronic kidney disease with type 2 diabetes: 1 mg once weekly

Ozempic is available in a few different options of prefilled pens when it comes to strength. The available injectable pens include a red pen that delivers 0.25 mg or 0.5 mg, a blue pen that delivers 1 mg, and a yellow pen that delivers 2 mg per dose. 

Other Instructions for Administering Ozempic

Do not inject Ozempic until your doctor or her staff demonstrate the technique. It’s important to keep the following in mind when using Ozempic:

• Ozempic is injected into the abdomen (stomach) area, thigh, or upper arm. It’s recommended to rotate to a different site each week, and not place injections too close together. 
• If insulin is being used with Ozempic, it’s best to keep the products separate. Ozempic and insulin should not be injected right next to each other.
• It’s possible to change the day of the week the injection is given, as long as it’s been at least 48 hours since the last dose. 
• For missed doses, Ozempic should be taken as soon as you realize you’ve missed it, unless it’s been more than 5 days. If 5 days have passed since the dose was missed, wait and take the next dose on its regularly scheduled day. 
• Ensure the solution is clear and colorless before injecting it. If there are any little particles  in the solution, or if it appears cloudy, do not use the solution. 

Storage is also a key part of using Ozempic correctly. Before using an Ozempic pen for the first time, it should be stored in a refrigerator between 36–46ºF (2–8ºC). After it’s been used, the pen can then be stored at room temperature (59–86°F or 15–30°C) for up to 56 days. Remember, typical body temperature is higher than this range, so don’t carry your pen in a pocket close to the body. In any case, the pen should be kept out of the sun and excessive heat. Do not freeze the pen. 

How Well Does Ozempic Work? (Trial Data)

Various trials have shown that Ozempic is effective at reducing blood sugar levels in adults with type 2 diabetes. The value used to measure Ozempic’s effectiveness is the hemoglobin A1c test, which shows the average blood glucose levels over the past 2–3 months. 

The SUSTAIN trials were the main studies that found that Ozempic reduced A1c levels by up to almost 2.0 % points on average after about a year of treatment. At the same time, these trials found that individuals lost around 9-13 lb (4-6 kg) of weight over the study period. The SUSTAIN FORTE trial also found that dose matters, with the higher dose of Ozempic working more effectively than lower ones to reduce A1c levels. SUSTAIN 6 showed that risk for heart problems and kidney disease was substantially reduced. FLOW showed a major reduction in all kidney problems and in heart disease deaths. 

*Table: The Efficacy of Ozempic in Clinical Trials

Trial Name	Population	Duration	Primary Focus	Key Outcomes
SUSTAIN 1–5, 7	Adults with type 2 diabetes	30–56 weeks	Blood sugar control	A1C reduced by around 1.0% to 1.8% on average; weight loss of around 4–6 kg (9–13 lb)
SUSTAIN FORTE	Adults with type 2 diabetes inadequately controlled on metformin	40 weeks	Blood sugar control	A1C reduced by up to around 2.1% with higher-dose semaglutide (2 mg) vs. lower-dose semaglutide (1 mg)
SUSTAIN-6	Adults with type 2 diabetes at high cardiovascular risk	104 weeks	Reduced risk of cardiovascular events	26% relative risk reduction in major adverse cardiovascular events (MACE); 39% reduction in new or worsening kidney disease
FLOW	Adults with type 2 diabetes and chronic kidney disease	Median 3.4 years	Progression of kidney disease	24% reduction in composite kidney outcome (kidney failure, sustained eGFR decline ≥50%, or death from cardiovascular causes)

These results reflect clinical trial results in controlled settings. Individual results may vary based on factors like dosage, adherence, lifestyle factors, and baseline laboratory values.          

The SUSTAIN-6 trial showed the advantage of using Ozempic for reducing the risk of cardiovascular events. In adults with type 2 diabetes and heart disease, Ozempic was able to reduce the risk of cardiovascular events like strokes and heart attacks by 26%. In addition, the FLOW trial found that Ozempic reduced the risk of complications like kidney failure by 24% in adults with type 2 diabetes and chronic kidney disease.

Ozempic Safety and Precautions

Ozempic has been shown to be a safe and effective medication when used as prescribed by a qualified healthcare provider. Most side effects are mild and temporary, and they’re usually linked to first starting treatment or increasing the dose. 

The most common side effects of Ozempic include:

• Nausea
• Constipation
• Vomiting
• Diarrhea
• Stomach pain

Serious side effects are also possible when using Ozempic. These are usually rare but may include the following:

• Pancreatitis (inflammation of the pancreas which may require hospitalization)
• Gallbladder problems (inflammation of the gallbladder which may require removal of gallbladder)
• Vision changes
• Hypoglycemia (low blood sugar)
• Food or liquids in the lungs while under anesthesia (pulmonary aspiration)
• Dehydration from kidney problems
• Severe stomach problems

Ozempic may also cause serious allergic reactions in some individuals who have a hypersensitivity to any ingredients in the drug. An allergic reaction could entail a skin rash, trouble breathing, or swelling of the face or throat. 

The FDA has also placed a black box warning on the drug label. Animal studies have shown that using GLP-1 drugs may increase the risk of thyroid tumors. Therefore, it’s recommended to avoid Ozempic in people with a personal or family history of thyroid cancer or multiple endocrine neoplasia syndrome type 2 (MEN 2). 

Still, some recent studies show that Ozempic does not increase the risk of thyroid cancer. It’s important to consult a healthcare provider about the potential risks before starting treatment. 

Drug Interactions and Special Populations

Ozempic may interact with other medications based on how it works. It’s important to discuss any medications being taken, including prescription drugs, over-the-counter medicines, and herbal supplements, before starting Ozempic.

Drug interactions with Ozempic may involve the following:

• Insulin and sulfonylureas: Taking Ozempic with insulin or a drug class for diabetes called sulfonylureas may increase the risk of hypoglycemia. This drug interaction could lead to dangerously low blood sugar levels, with dosages potentially needing to be changed if these drugs are taken together. 
• Oral medications: Ozempic can decrease the slowing of movement in the stomach, which means taking medications by mouth could be affected. Ultimately, Ozempic could decrease the absorption of oral drugs and could cause concern for medications that rely on specific absorption rates in order to work well, such as warfarin.

In addition, Ozempic may interact with alcohol, though indirectly through effects on blood sugar. Drinking alcohol on Ozempic may increase the risk of hypoglycemia and even amplify certain side effects like nausea or stomach upset. 

Ozempic may need to be used with caution in certain people, especially the following:

• Women who are pregnant or breastfeeding
• People with a history of pancreatitis
• People with a history of diabetic eye problems
• People with serious gastrointestinal problems

Always discuss your full medical history, including health conditions and other medications being taken, before taking Ozempic for the first time. Ozempic is not currently approved for children under 18. 

Access, Cost, and Coverage of Ozempic

As a brand-name drug, Ozempic can come with high costs, often reaching over $1,000 per month. No generic version is currently approved, which means there are no official lower-cost alternatives.

The cost of Ozempic can depend on different factors, such as insurance coverage, pharmacy, location, dosage, and quantity prescribed. Some commercial insurance plans may offer coverage for Ozempic when it’s prescribed for approved conditions. Medicare and Medicaid coverage will vary. 

The out-of-pocket costs can still be high with insurance, especially for those who haven’t met their plan’s deductible. These costs can include a copay, which is a fixed price, or a coinsurance amount, which is a percentage you owe based on the plan’s coverage policy. 

There may be different ways to save on Ozempic, including manufacturer savings cards, patient assistance programs, and discount cards. These methods may come with different eligibility requirements, so it’s important to check the available options. Saving could also be as simple as comparing the price at different pharmacies or trying compounded versions of semaglutide from a reputable platform.

Policy Lab partners with OnlineSemaglutide to offer compounded GLP-1 medications like semaglutide and tirzepatide at a reduced cost. Compounded semaglutide contains the same active ingredient as Ozempic and can offer similar effects for managing blood sugar levels. Still, using them with guidance from a healthcare provider is key to getting the most benefit.

How Research Shapes Treatments

The science behind Ozempic has been tested and proven through numerous clinical trials. Its approval has come from the rigorous testing of thousands of participants across various studies. These clinical trials are also responsible for uncovering the cardiovascular benefits of Ozempic, with future trials yet to be done that could show other benefits. 

Clinical trials depend on volunteers, with both the individual and the broader community benefiting from the results. These trials may lead to new dosing schedules, new drug combinations, and new uses for different groups of people.

For those interested in clinical trial opportunities, Policy Lab offers a database of current studies along with educational resources about what participation involves. The platform helps connect individuals with studies that match their health profile and interests.

FAQs 

Can I Use Ozempic for Weight Loss If I Don’t Have Diabetes?
