How GLP-1 Injections Are Used

What Is a GLP-1 Injection?

GLP-1 stands for glucagon-like peptide-1, a hormone the body naturally produces in the gut in response to eating. It plays a role in blood sugar regulation, digestion, and appetite signaling.

GLP-1 receptor agonists are medications that mimic this hormone. In injection form, they are designed to be slowly absorbed into the bloodstream to activate these receptor pathways over time.

Because GLP-1 medications are peptides, they can’t be taken as standard pills without special formulations; the digestive system would break them down before they take effect. As a result, most GLP-1 therapies are delivered through subcutaneous injection, a small needle just under the skin.

How Are GLP-1 Injections Administered?

GLP-1 injections are typically self-administered at home after initial instruction from a healthcare provider. They come in prefilled injection pens, which are designed for ease of use with minimal steps.

General administration steps may include:

• Choosing a clean injection site (commonly the stomach, thigh, or upper arm)
  
• Attaching or checking the needle (depending on the device)
  
• Dialing the prescribed dose if required
  
• Inserting the needle under the skin and pressing the button to release the medication
  
• Disposing of the needle safely in a sharps container
  
  

Most patients find that the process becomes routine with practice. Many injection pens are single-use and pre-measured, which may reduce the risk of error.

How Often Are Injections Given?

Dosing frequency depends on the specific GLP-1 prescribed:

• Once-daily injections (e.g., liraglutide) are typically taken at the same time every day.
  
• Once-weekly injections (e.g., semaglutide, dulaglutide) offer more flexibility, allowing for administration with or without meals.
  
  

A provider will select the appropriate starting dose and may gradually increase it based on the patient's tolerance and treatment goals. Dosing adjustments are common and are tailored to each individual by their provider.

What to Expect After Starting GLP-1 Injections

It’s common for licensed providers to start patients at a lower dose, which may minimize side effects and build tolerance. Common experiences may include:

• Nausea
  
• Decreased appetite
  
• Mild gastrointestinal discomfort
  
• Injection site tenderness
  
  

These side effects are typically temporary and may subside as the body adjusts to the medication. A licensed provider will monitor your response and determine whether the medication remains suitable over time.

It’s important to follow your provider’s instructions carefully, including proper storage and disposal of the medication.

GLP-1 Injections and Lifestyle

GLP-1 injections may be part of a broader strategy that includes:

• Balanced nutrition
  
• Regular movement
  
• Sleep and stress management
  
• Routine check-ins with your provider
  
  

GLP-1 medications are not a standalone solution, and their effectiveness may depend on how they’re incorporated into a full treatment plan.

Licensed healthcare providers on the Eden platform can help you create a personalized plan that aligns with your lifestyle and goals.

Are GLP-1 Injections Right for You?

GLP-1 injections may not be suitable for everyone. A licensed provider will consider multiple factors during your evaluation, such as:

• BMI and weight-related conditions
  
• Blood sugar levels and insulin sensitivity
  
• Current medications and health history
  
• Willingness to self-administer injections
  
• Tolerance and preferences regarding daily vs. weekly dosing
