Before Your First Dose: How to Prepare for a GLP-1 Medication

Ready to start your GLP-1 journey? From stocking your kitchen to managing side effects, here’s how to prepare for your first dose of Ozempic, Wegovy, or Mounjaro.

Starting a GLP-1 medication is a big step. Whether your doctor just prescribed Ozempic, Wegovy, Mounjaro, or Zepbound, the days before your first injection can feel exciting and a little nerve-wracking at the same time.

Here's how to walk into that first dose feeling completely prepared.

Talk to Your Provider About What to Expect

Before anything else, make sure you've had a clear conversation with your prescribing doctor or nurse practitioner. You'll want to understand your starting dose (most GLP-1 medications begin at the lowest available strength), the titration schedule your provider recommends, which side effects are most common in the first few weeks, and when to call them if something feels off.

Don't be afraid to ask questions. Write them down ahead of time if that helps. This is your journey, and your provider is your partner in it.

Stock Your Kitchen Before Day One

GLP-1 medications suppress appetite, sometimes dramatically. That means the food you keep on hand matters more than ever, because you'll be eating less of it.

Focus on high-protein, easy-to-digest options. Think Greek yogurt, eggs, lean deli meat, cottage cheese, protein shakes, and bone broth. These foods are gentle on the stomach and help protect your muscle mass while you lose weight.

Keep bland, soothing foods available too. Crackers, bananas, applesauce, and rice are go-to options for days when nausea shows up.

Hydrate Like It's Your New Job

This one is non-negotiable. GLP-1 medications slow gastric emptying, which can affect your thirst signals. Many people become mildly dehydrated without even realizing it.

Aim for 64 to 100 ounces of water per day, about 2 to 3 liters. Buy a large reusable water bottle (32 to 40 ounces) and keep it with you everywhere.

Know How to Store Your Medication

Most GLP-1 pens (Ozempic, Wegovy, Mounjaro, Zepbound) need to be refrigerated before first use. After the first injection, many can be kept at room temperature for a set number of days. Check your specific medication's labeling.

Never freeze your pen. Keep it away from direct sunlight. If you're traveling, use an insulated medication pouch or small cooler to maintain the proper temperature range.

Gather Your Supplies

Beyond the medication itself, here's what to have on hand: alcohol swabs for cleaning the injection site, a sharps container for used pen needles or syringes (a heavy-duty plastic container with a tight lid works in a pinch), and a simple tracking method for logging your doses.

Choose Your First Injection Site

GLP-1 injections are subcutaneous, meaning they go into the fatty tissue just beneath the skin. The most common sites are the abdomen (at least two inches from the belly button), the front of the thigh, and the back of the upper arm.

Rotate your injection site each time to reduce the chance of irritation or lipodystrophy. Many people find the abdomen to be the least painful spot, but everyone is different. GLPeak's injection site tracker can help you remember where you injected last.

Set Realistic Expectations

Here's the truth: most people don't see dramatic changes in the first week. Your starting dose is deliberately low to help your body adjust. The appetite suppression often kicks in gradually over the first two to four weeks.

Some people feel nauseous. Some feel nothing at all. Both are normal. The goal in month one isn't rapid weight loss, it's building the habits and routines that will carry you through the months ahead.

Your First-Day Checklist

You've got this. The first injection takes about ten seconds. Everything else is just showing up for yourself, one day at a time.
