A Week-by-Week Checklist for Your First Month on a GLP-1 — Medicare Edition

You picked up your first GLP-1 prescription through the Medicare Bridge program. The pen is in your refrigerator. Now what? The first month on a medication like Wegovy or Zepbound can feel overwhelming, especially when you are not sure what is normal and what deserves a phone call to your doctor. This week-by-week checklist breaks everything down into small, manageable steps so you always know exactly what to do next.

Before Your First Injection: The Prep Checklist

Do not wait until injection day to get organized. A little preparation during the days before your first dose makes the entire first week easier.

• Confirm your prior authorization is approved and your pharmacy has the medication in stock
• Read the manufacturer's instructions for your specific pen device — each brand works slightly differently
• Stock your kitchen with easy-to-digest proteins like Greek yogurt, eggs, cottage cheese, and low-sugar protein shakes
• Buy a simple digital food scale if you do not already own one — portion sizes will matter more than ever
• Fill a large water bottle and set a goal of at least 64 ounces per day
• Choose an injection day that gives you a quiet day or two afterward in case you feel nauseated
• Set up a simple tracking system — a notebook, a spreadsheet, or a free app like CairnSpace — to log meals, water, symptoms, and weight

Week 1: Your First Injection and What to Expect

The first week is mostly about getting comfortable with the injection itself and paying attention to how your body responds. You are starting on the lowest dose, so effects are usually mild.

Injection Day

• Take the pen out of the refrigerator 30 minutes before injection to let it reach room temperature
• Inject into your abdomen, thigh, or upper arm — rotate the site each week
• The needle is very small and most people describe it as a brief pinch, not real pain
• Eat a light meal within an hour of your injection — do not inject on a completely empty stomach
• Log the injection site, time, and any immediate sensations in your tracker

Days 2 Through 7

• Eat small meals every three to four hours even if you do not feel hungry — skipping meals leads to nausea and fatigue
• Prioritize protein at every meal: aim for 20 to 30 grams per meal, or at least 60 grams total per day
• Drink water steadily throughout the day — dehydration is one of the most common early problems
• Expect mild nausea, slight bloating, or a reduced appetite — all are normal at this stage
• Take a 10- to 15-minute walk after meals if you are able — it helps digestion and blood sugar
• Log your meals, water intake, and any symptoms daily
• Call your doctor if you experience severe nausea that prevents eating, vomiting that lasts more than 24 hours, or sharp abdominal pain

Week 2: Building Your New Eating Routine

By the second week, most people notice their appetite has genuinely decreased. This is the medication working as intended, but it creates a new challenge: making sure you eat enough of the right foods even when you do not feel like eating.

• Continue logging meals and water — patterns will start to emerge that help you plan better
• If solid food feels unappealing, try protein shakes, smoothies, or warm broth-based soups
• Weigh yourself once at the beginning of the week under consistent conditions — same time, same clothing
• Start a simple strength routine if your doctor approves: chair squats, wall push-ups, or resistance bands for 10 to 15 minutes three times per week
• Watch for constipation — increase fiber gradually and consider a stool softener if needed (ask your pharmacist)
• Review your other medications with your pharmacist to confirm timing is still appropriate — GLP-1 medications can slow absorption of some oral drugs
• Note any improvement in blood sugar readings if you have diabetes — your doctor may need to adjust insulin or sulfonylurea doses to prevent lows

Week 3: Recognizing What Is Working and What Needs Adjustment

The third week is when you start to see real signals. Side effects that appeared in week one may be fading. Your eating patterns are more established. This is a good time to take stock and prepare for your follow-up appointment.

• Review your tracking log for the past two weeks — look for patterns in what foods sit well, what times of day are hardest, and whether your water intake is consistent
• If nausea has not improved at all, write down exactly when it happens (before meals, after meals, at night) so you can give your doctor useful detail
• Check whether your daily protein target is realistic — if you are consistently falling short, add a protein shake or a handful of nuts as a daily habit
• Measure your waist with a tape measure and record it — the scale does not always reflect fat loss, especially if you are doing strength exercises
• Make a list of questions for your doctor: Are my blood sugar changes expected? Should any medication doses change? When do I move to a higher GLP-1 dose?
• If you are using CairnSpace or another tracker, review your weekly summaries — seeing progress over time is motivating and gives your doctor useful data

Week 4: Preparing for Your Follow-Up and the Next Dose Level

Most GLP-1 medications follow a titration schedule where the dose increases after four weeks. Your doctor will decide whether you are ready to move up. This week is about consolidating your habits and arriving at that appointment well-prepared.

• Schedule your follow-up appointment if you have not already — most doctors want to see you around the four-week mark
• Bring your tracking log or a printed summary to the appointment — doctors appreciate patients who come with data
• Weigh yourself and record the number alongside your starting weight for a clear comparison
• Prepare to discuss: weight change, side effects, appetite changes, exercise, blood sugar trends, and how you feel overall
• Ask your doctor about dose escalation timing and what new side effects to watch for at the higher dose
• Refill your protein-friendly groceries — the foods that worked during month one are your foundation going forward
• Confirm your next month's prescription is authorized and your pharmacy expects it — Medicare Bridge prescriptions route through a specific processor, so do not assume auto-refills work the same way
• Celebrate that you completed the hardest month — the first four weeks are the biggest adjustment period, and everything after this builds on what you have already learned

What Should You Be Tracking Every Day?

You do not need to track 20 different metrics. Focus on five things that give you and your doctor the clearest picture of how the medication is working.

• Protein intake — aim for 60 grams minimum per day, more if your doctor recommends it
• Water intake — at least 64 ounces per day, more in warm weather or if you exercise
• Symptoms — note anything new or changing, including nausea, fatigue, constipation, or dizziness
• Movement — even a short walk counts; record what you did and for how long
• Weight — once per week under consistent conditions is enough; daily weigh-ins cause unnecessary stress

CairnSpace is a free companion platform designed specifically for GLP-1 users to log these daily metrics. It is private, requires no insurance information, and gives you simple weekly summaries you can share with your doctor.

When to Call Your Doctor Before Your Follow-Up

Most side effects during the first month are mild and manageable. However, some symptoms warrant a phone call before your scheduled appointment.

• Vomiting that lasts more than 24 hours or prevents you from keeping liquids down
• Severe abdominal pain, especially in the upper abdomen radiating to your back
• Signs of low blood sugar if you take insulin or sulfonylureas: shakiness, sweating, confusion, rapid heartbeat
• Dizziness or fainting when standing up — this can indicate dehydration
• Any allergic reaction: rash, swelling, or difficulty breathing
• A lump or persistent pain at the injection site that does not resolve within a few days

When in doubt, call. Your doctor's office would rather hear from you early than deal with a preventable complication later.

Common First-Month Mistakes to Avoid

• Skipping meals because you are not hungry — your body still needs protein and nutrients even when appetite is suppressed
• Not drinking enough water — GLP-1 medications slow digestion, and dehydration makes every side effect worse
• Expecting dramatic weight loss in the first two weeks — the starting dose is intentionally low to let your body adjust
• Stopping the medication because of mild nausea without talking to your doctor first — most nausea improves significantly by week three or four
• Forgetting to rotate injection sites — using the same spot repeatedly can cause skin irritation or lumps
• Not telling your pharmacist about all your other medications — timing interactions are real and easy to manage once identified

What to Expect After Month One

Once you complete the first month, the pattern becomes familiar. Dose increases happen on a schedule your doctor controls, and each increase may bring a brief return of mild side effects that usually fade within a week. Most Medicare Bridge participants see meaningful weight loss between months two and four as the dose reaches therapeutic levels.

The habits you build in month one — consistent protein, steady hydration, daily tracking, regular movement — are the same habits that determine long-term success. There is no secret phase two. The fundamentals you are practicing right now are the entire program.
