Semaglutide has gained significant attention as an effective weight loss medication. It is a GLP-1 (glucagon-like peptide-1) receptor agonist used for maintaining blood glucose levels in patients with type 2 diabetes and weight loss management in people with obesity or overweight when used in combination with exercise and dietary changes. The U.S. Food and Drug Administration (FDA) approved it for chronic weight loss management in 2021.
Before starting your semaglutide treatment, it is necessary to know the correct dosage to achieve desired results and avoid adverse effects.
This article details the correct semaglutide weight loss dosage, dose adjustment, and explains how semaglutide promotes weight loss.
What is semaglutide?
Semaglutide is an active ingredient in Wegovy, Ozempic, Rybelsus, and compounded semaglutide. Semaglutide promotes weight loss by mimicking GLP-1 hormones to suppress appetite. Moreover, it delays gastric emptying to give you a feeling of fullness.
Currently, semaglutide is FDA-approved for weight loss under the brand name Wegovy. Ozempic and Rybelsus are used off-label for weight management. A study shows that when used with lifestyle changes, the weekly 2.4 mg dose of semaglutide reduced 10-15% of body weight compared to the placebo, which reduced body weight by only 2-3%.
Wegovy (semaglutide) injection was approved by the U.S. Food and Drug Administration for chronic weight management in combination with a low-calorie diet and increased physical activity. The drug is suitable for chronic weight management in patients with:
- Obesity (body max index equal to or greater than 30), or;
- Overweight (body mass index equal to or greater than 27) with at least one weight-related problem such as high cholesterol, hypertension, or type 2 diabetes.
Rybelsus (semaglutide) is the first FDA-approved oral GLP-1 agonist for patients with type 2 diabetes to improve blood sugar levels when combined with exercise and lifestyle changes.
Ozempic (semaglutide) is an FDA-approved subcutaneous injection for managing blood glucose levels in type 2 diabetes as an adjunct to diet and exercise.
Semaglutide is also used to reduce the risk of cardiovascular events such as stroke and hypertension in patients with type 2 diabetes and cardiovascular disease.
How does semaglutide work?
Semaglutide works by targeting glucagon-like peptide 1 (GLP-1) receptors in the body. Glucagon-like peptide-1 is a hormone released after you eat food. By targeting the brain areas that regulate food and hunger, semaglutide suppresses appetite. The medication improves the growth of pancreatic beta cells to promote insulin production and secretion. By binding with GLP-1 receptors, semaglutide suppresses appetite, increases insulin secretion, delays gastric emptying, stimulates glucose-dependent sections of insulin, and reduces food intake to promote weight loss.
How does semaglutide help with weight loss?
As semaglutide suppresses appetite and delays gastric emptying, patients do not feel an urge to eat frequently, which helps with weight loss and weight management.
Semaglutide converts white adipose tissues into brown adipose tissues, a phenomenon called adipose tissue browning, and reduces dysfunctional adiposity in obesity. Brown adipose tissues generate body heat. They burn triglycerides into free fatty acids that are oxidized to generate heat. In contrast, white adipose tissues store excess fat and decrease energy expenditure. These are also responsible for the disfigurement of the body.
Research studies show that semaglutide converts white adipose tissues into brown ones that increase mitochondrial activity and fat-burning capacity. The medication enhances “browning” in adipose tissues. This suggests that semaglutide could potentially accelerate metabolism, reduce weight gain, and improve insulin sensitivity, all of which help with weight loss.
A research study shows that semaglutide users are less interested in high-calorie foods like carbonated drinks, sugary snacks, and processed foods. Reduced calorie intake also helps with weight loss.
According to clinical trial studies, once weekly semaglutide 2.4 mg shows mean weight loss of 14.9-17.4% and improvement in physical functions and quality of life in non-diabetics. The dosage of semaglutide is typically adjusted based on the patient’s body mass index.
Semaglutide weight loss dosage chart
Semaglutide, which is injected under the skin (subcutaneously), is prescribed under the brand name Wegovy for weight loss. It’s also compounded using the same active ingredient as the brand name drug.
Weekly dosage schedule
Starting dose: 0.25 mg weekly for first 4 weeks
Titration phase: 0.5 mg weekly for 4 weeks and then, if tolerated, 1 mg weekly for 4 weeks
Maintenance dose for long-term weight management: 1.7 mg once weekly for 4 weeks and then, if tolerated, 2.4 mg once weekly (maximum dose)
Dosing considerations
If you do not tolerate dose escalation, consult with your healthcare provider and consider delaying the dose escalation for at least 4 weeks.
If you cannot tolerate a maintenance dose of 2.4 mg once weekly, consider with your healthcare provider about decreasing the maintenance dose to 1.7 mg once a week.
After 4 weeks, if your healthcare provider permits, escalate the dose back to 2.4 mg once a week. If you still cannot tolerate the maintenance dose of 2.4 mg once weekly, speak with your healthcare professional about decreasing the maintenance dose to 1.7 mg once a week.
Semaglutide vs. compounded semaglutide
Semaglutide is a once-weekly injectable prescription medication that is available under the brand name Wegovy for weight loss, and is also available under the brand name Ozempic for type 2 diabetes.
Compounded semaglutide is an affordable GLP-1 alternative that contains the same active ingredient as Wegovy and Ozempic, and is manufactured by semaglutide compounding pharmacies to suit the specific needs of patients. Healthcare providers may prescribe compounded semaglutide with a customized formulation that is tailored to an individual patient’s needs.
Compounded semaglutide weight loss dosage chart
The weight loss journey with compounded semaglutide also includes a gradual escalation in dose to minimize potential side effects while the body gets used to the medication. A typical compounded semaglutide dosage chart for weight loss is included below. You should take into consideration that dosing may vary by compounding pharmacy as compounded medications are tailor-mode for each individual patient.
Weekly dosage schedule
Starting dose: 0.25 mg weekly for first 4 weeks
Titration phase: 0.5 mg weekly for 4 weeks and then, if tolerated, 1 mg weekly for 4 weeks
Maintenance dose for long-term weight management: 1.75 mg weekly for 4 weeks and then, if tolerated, 2.5 mg weekly (maximum dose)
The dosage may vary depending on the individual needs, your initial BMI, and glycemic control. If you observe any side effects, consult your healthcare provider immediately.
How to use the dosage chart safely
When starting a new medication, especially for weight loss, it is necessary to learn about the correct dosage, as GLP-1 receptor agonists can alter blood glucose levels. Always take these medications exactly as prescribed by your healthcare provider. They will adjust the dosage according to your body’s needs and tolerance for side effects.
The dosage of semaglutide depends on several factors, including weight plateau, your medical conditions, age, gender, nutritional status, BMI, hormonal status, and side effects. Similarly, the dose escalation also depends on your tolerability. If you cannot tolerate the dose escalation, it is recommended to delay dose escalation for 4 weeks. If dose escalation is still not tolerated after 4 weeks, discontinue semaglutide after discussing with your healthcare provider. They will make a tailored dosage plan according to your body’s needs and blood glucose levels.
If you experience a severe allergic reaction (swelling of face, eyes, and lips, itching, dizziness, and difficulty breathing), gallbladder inflammation, changes in vision, or low blood sugar levels, stop using the medication and get medical help right away.
Semaglutide is injected subcutaneously (under the skin). The most suitable sites for semaglutide injection are the abdomen, upper thigh, and the back of the upper arm. When you inject in your abdomen, choose a suitable spot 2 inches from your belly button. Similarly, the front of the upper thighs and back of the upper arm are also optimal sites for semaglutide injection.
Follow these steps to safely inject semaglutide:
- Gather all necessary supplies, such as syringe, needle, and an alcohol swab.
- Wash your hands, select the injection site, and clean the area with an alcohol swab.
- Prepare the injection and hold the syringe at 90 degrees to the skin.
- Insert the needle steadily and inject the medication.
- Safely dispose of the used syringe, needle, and other supplies.
- If you observe any changes in skin color, irritation, or discomfort, change the injection site.
Mild side effects like nausea and gastrointestinal issues are common with semaglutide. These side effects should subside over time as your body gets used to the medication. If you experience severe side effects and that do not subside with time, stop taking semaglutide and consult your doctor.
Importance of following the correct weight loss dosage schedule
Clinical studies demonstrate that semaglutide dose escalation in clinical trials shows significant improvement in HbA1c levels. However, it is recommended to escalate the dose slowly, as semaglutide is associated with gastrointestinal side effects. Slow dose escalation improves tolerance and minimizes the potential risks.
Lower doses and missed or delayed doses lower the effectiveness of semaglutide. If you repeatedly miss doses, you may need to restart the treatment. To get maximum results, follow your dosage schedule as recommended by your healthcare provider.
A rapid escalation is associated with low blood sugar levels and severe GI side effects such as severe abdominal pain, nausea, vomiting, and inflammation of the pancreas (pancreatitis). When using semaglutide, avoid rapid dose escalation as it can cause GI upset, vomiting, abdominal pain, and diarrhea. Moreover, it can also cause hypoglycemia (low blood glucose levels). Symptoms of low blood sugar levels include dizziness, blurred vision, confusion, headache, shakiness, and even seizures and loss of consciousness in severe cases.
Always follow the dosing plan prescribed by your healthcare provider.
What happens if you miss a dose of semaglutide?
If you miss a dose of semaglutide injection, take it as soon as possible, within 5 days of a missed dose. Take the next dose on the next scheduled date. When the next dose is less than 2 days away, skip the missed dose and take the next dose on the next scheduled date. However, skipping a dose may decrease the effectiveness of semaglutide. If you miss 2 or more doses of the medication, consult your healthcare practitioner for medical advice.
