This guide breaks down exactly what happens in your body after each semaglutide injection , when the most common side effects typically appear, how long they last at each dose level, and what the STEP trial data actually shows about the timeline from first injection to peak side effects
Pre-injection preparation techniques include: Cleaning the injection site with an alcohol swab and allowing it to dry completely (wet alcohol can cause stinging and tissue irritation) Refraining from rubbing or massaging the injection site before or immediately after injection Using standard 4-mm, 32G pen needles, which minimize tissue trauma for most patients Applying firm pressure (without rubbing) with a clean gauze pad or cotton ball for at least 2 minutes after needle withdrawal, especially for patients on blood thinners For patients taking anticoagulants or antiplatelet medications, do not change your medication dosing or timing for injections
During your visit, the provider evaluates whether medication is safe and appropriate for you
