<h1 class="ondra-article-title">Your First GLP-1 Injection: What to Expect and How to Do It</h1>
<p class="ondra-article-intro">Your first injection is the moment most patients feel nervous about — and almost universally report was easier than expected. This guide covers what arrives in your first shipment, how to prepare, where to inject, and what to do in the hours afterward. Follow the specific instructions provided with your medication and by your provider; if anything about your supplies or dose looks different from what you expected, ask before injecting.</p>

<div class="ondra-section">
<h2>What arrives in my first shipment?</h2>
<p>Your medication ships cold-chain in insulated packaging with gel packs. Inside you'll find your vial or pen, the supplies needed to administer your dose, and instructions specific to your medication and dose. Refrigerate the medication as soon as it arrives.</p>
<div class="ondra-info-card">
<p class="ondra-info-title">Check before your first dose</p>
<p>Confirm the medication name and dose on the label match what your provider prescribed. Look at the medication itself — it should look normal for its formulation, without unexpected particles or discoloration. If anything doesn't match what you expected, message your care team before injecting rather than proceeding and asking after.</p>
</div>
</div>
<div class="ondra-section">
<h2>Where do I inject?</h2>
<p>GLP-1 medications are given as subcutaneous injections — into the fat layer just under the skin, not into muscle. The three standard sites are the abdomen (at least two inches away from the navel), the front or outer thigh, and the back of the upper arm.</p>
<p>Rotate your site each week rather than using the same spot repeatedly. Rotating reduces irritation and lumpiness at the injection site over time. Many patients cycle through sites in a fixed order so they don't have to remember where they went last.</p>
</div>
<div class="ondra-section">
<h2>How do I actually give the injection?</h2>
<p>Follow the specific instructions that came with your medication — they take precedence over any general description. Broadly, the process is: wash your hands, prepare your dose as instructed, clean the injection site with an alcohol swab and let it dry, pinch a fold of skin if directed, insert the needle, deliver the dose, and dispose of the needle in a sharps container.</p>
<p>The needles used are very short and fine. Most patients describe the sensation as a brief pinch or nothing at all. Injecting into skin at room temperature and letting the alcohol dry fully both tend to reduce stinging.</p>
<p>If you're uncertain about any step, don't improvise — message your care team through the <a href="https://care.ondra.health" target="_blank" rel="noopener">patient portal</a> and ask.</p>
</div>
<div class="ondra-section">
<h2>What day and time should I inject?</h2>
<p>Any day works, but consistency matters more than the specific choice. Pick a day you're reliably home and unhurried, and make that your weekly anchor. Many patients choose a weekend morning or a weekday evening.</p>
<p>Some patients prefer injecting in the evening so that any early side effects occur overnight. Others prefer mornings so they can monitor how they feel during the day. There's no universally correct answer — pick what fits your life, since you'll be repeating it weekly.</p>
</div>
<div class="ondra-section">
<h2>What should I expect in the first 24 hours?</h2>
<p>Many patients feel little or nothing after the first dose, since you start at the lowest dose. Some notice mild nausea, reduced appetite, fatigue, or mild injection-site tenderness. These are common and often ease as your body adjusts.</p>
<p>Eat lightly rather than heavily, stay hydrated, and pay attention to how you feel. If you experience severe or persistent symptoms — severe abdominal pain, persistent vomiting, or signs of an allergic reaction — seek medical care promptly rather than waiting.</p>
