GLP-1 Beginner's Guide: Your First Month

After you complete the 5-minute online health evaluation, your information is transmitted securely to an independent licensed medical provider. The provider reviews your full health profile, medical history, current medications, weight history, and goals. This review typically takes 24–72 hours. If the provider has clarifying questions, they will reach out through secure messaging. You will receive a clear decision: either a personalized prescription and care plan if clinically appropriate, or an explanation of why treatment may not be suitable and recommendations for next steps.

Provider review means a real, independent licensed medical provider — a physician or nurse practitioner credentialed in your state — personally examines your health information. This is not an algorithm or automated approval. The provider assesses whether GLP-1 therapy is clinically appropriate for your individual case, selects an appropriate starting dose, designs a titration schedule, and determines whether any additional monitoring is needed. All prescribing decisions are made solely by the provider. Open Water Rx does not direct or influence those decisions.

During the first week, you will take your first low-dose injection — typically 0.25mg weekly for semaglutide or 2.5mg weekly for tirzepatide. Most patients notice appetite reduction within 1–3 days. Common early experiences include mild nausea, bloating, or stomach discomfort as your body adjusts. These are usually temporary and improve over the first 2–4 weeks. Focus on hydration, small protein-rich meals, and rest. Individual responses vary and are not guaranteed.

Weight loss during the first month varies significantly between individuals. Most patients lose 2–5 pounds in the first 4 weeks, though some may experience more rapid initial changes. The first month is primarily a titration phase where your provider adjusts your dose to find your optimal therapeutic level. Meaningful, sustained weight loss typically becomes more apparent in months 2–4 as you reach higher therapeutic doses. Individual results vary and are not guaranteed.

Common side effects include nausea, vomiting, diarrhea, constipation, abdominal cramping, bloating, fatigue, and headache. Nausea is the most frequently reported symptom. These are usually mild to moderate and tend to improve as your body adjusts to the medication. Your provider starts you at a low dose and increases gradually to minimize these effects. If side effects are severe or persistent, contact your provider immediately through secure messaging.

Contact your provider promptly through secure messaging if you experience severe or persistent nausea or vomiting, signs of dehydration, severe abdominal pain, gallbladder-related symptoms (upper right abdominal pain, fever, yellowing skin), allergic reactions, chest pain, shortness of breath, or any symptom that concerns you. Do not stop medication without consulting your provider first, unless you are experiencing a medical emergency. For emergencies, call 911 or go to the nearest emergency room.

If prescribed, your medication ships discreetly from a licensed compounding pharmacy directly to your address. Packaging is plain and unmarked — no branding or medication labels visible externally. Shipping is included in your plan price. Refrigerated medications ship with cold-chain packaging. Your health data is encrypted end-to-end and handled in strict accordance with HIPAA privacy standards. Open Water Rx never sells your data.

Compounded semaglutide programs start at $169/month and tirzepatide programs start at $219/month. Both include provider review, medication if prescribed, shipping if prescribed, and ongoing support. Eligibility generally requires age 18+, BMI 27+ with a weight-related condition (or BMI 30+), and no contraindications such as personal or family history of MTC or MEN 2. Final eligibility is determined by an independent licensed provider. Not all patients qualify. Available nationwide in all 50 states.

Do not change your dose, skip doses, double doses, or stop medication without consulting your provider. Do not share your medication with anyone else. Do not combine GLP-1 therapy with other weight loss medications or supplements without provider approval. Do not pursue extreme diets, fasting, or intense exercise regimens without discussing them with your provider first. Do not ignore persistent or severe side effects. Always follow your provider's prescribed plan.

Tirzepatide is a dual GIP/GLP-1 receptor agonist, meaning it activates two metabolic pathways simultaneously, while semaglutide is a single GLP-1 receptor agonist. For beginners, tirzepatide may produce more pronounced appetite suppression and greater average weight loss in clinical trials with FDA-approved formulations. However, some patients report more side effects with tirzepatide, particularly at higher doses. Semaglutide may be preferred for patients with a history of medication sensitivity. Your provider will recommend the appropriate medication based on your health profile.

Many patients find light to moderate exercise tolerable during the first month, but individual tolerance varies. Start gradually, especially if you experience fatigue or nausea. Focus on low-impact activities like walking, swimming, or gentle cycling. Resistance training may help preserve lean muscle mass, but discuss any exercise plan with your provider before starting. Listen to your body and avoid intense workouts if you feel unwell.

If you miss a dose, contact your provider through secure messaging for specific guidance. Do not take extra doses or make up missed doses without provider direction. Your provider will advise you based on how much time has passed and your current treatment plan. Consistency is important, so setting a weekly reminder can help.
