This article is for informational and educational purposes only and does not constitute medical advice. GLP-1 medications are prescription drugs. Side effect information presented here is drawn from FDA-approved semaglutide and tirzepatide labeling and published clinical literature — it is not specific to any compounded formulation. Compounded medications have not undergone the same FDA safety and efficacy review as brand-name products. Always consult your prescribing clinician before starting, adjusting, or stopping any prescription medication. If you are experiencing a medical emergency, call 911 immediately.
What This Article Is and Isn't
If you're researching Wellorithm and trying to understand what to expect from semaglutide or tirzepatide before you start, this is the article that fills in what the platform's intake page doesn't have space for.
One important framing note upfront: Wellorithm's program involves compounded semaglutide and compounded tirzepatide, not the FDA-approved brand-name products. The side effect information in this article is drawn from the established clinical literature and FDA labeling for the FDA-approved formulations — Wegovy (semaglutide), Ozempic (semaglutide), Zepbound (tirzepatide), and Mounjaro (tirzepatide). Compounded formulations have not undergone the same FDA safety review, and the clinical evidence base does not extend to specific compounded products. Your prescribing clinician is the appropriate source for side effect expectations specific to your compounded prescription.
The Common Side Effects: What Most People Experience
The most commonly reported side effects of GLP-1 receptor agonist medications are gastrointestinal in nature. Based on the FDA-approved semaglutide (Wegovy) prescribing information and clinical trial data:
Nausea is the most frequently reported side effect, particularly during the dose escalation period when the dose is being increased. In clinical trials of FDA-approved semaglutide for weight management, nausea was reported in a substantial portion of participants during the escalation phase and declined over time as the body adjusted. Eating smaller meals, avoiding high-fat foods, and not lying down immediately after eating can reduce nausea severity for many patients.
Vomiting, diarrhea, and constipation are also reported frequently, again most commonly during dose escalation. These effects are related to the mechanism by which GLP-1 medications slow gastric emptying — the same mechanism that contributes to their appetite-reducing effect. Staying well hydrated is particularly important if you experience diarrhea, and adequate fiber intake matters if constipation is the issue. (Interestingly, the need to manage constipation on GLP-1 therapy is something gelatin trick users are already familiar with — the gelatin protocol has its own constipation considerations.)
Abdominal discomfort and indigestion round out the common GI symptom profile. For most patients on FDA-approved formulations, these effects were manageable and diminished after the escalation period.
Fatigue and headache are reported less commonly but appear in the clinical literature. Reduced caloric intake on GLP-1 therapy — a direct result of the medication's appetite-suppressing mechanism — may contribute to fatigue in some patients, particularly early in treatment.
The Serious Risks: What Warrants Immediate Clinician Contact
This section is the reason this article exists. These risks are documented in FDA-approved labeling and are worth understanding before you start.
Pancreatitis: Acute pancreatitis has been reported with GLP-1 receptor agonist medications. If you develop severe, persistent abdominal pain — which may radiate to your back — while on GLP-1 therapy, this warrants immediate contact with your clinician or emergency care. Do not assume it is ordinary abdominal discomfort.
Thyroid C-cell tumors: In animal studies, GLP-1 receptor agonists have been associated with thyroid C-cell tumors. It is unknown whether this risk translates to humans, but the FDA's prescribing information includes a Boxed Warning — the most serious warning category — for the risk of thyroid C-cell tumors including medullary thyroid carcinoma (MTC). GLP-1 medications are contraindicated in patients with a personal or family history of MTC or in patients with Multiple Endocrine Neoplasia syndrome type 2 (MEN 2). If you develop a lump in your neck, hoarseness, difficulty swallowing, or difficulty breathing while on GLP-1 therapy, contact your clinician promptly.
Gallbladder issues: Cholelithiasis (gallstones) and cholecystitis (gallbladder inflammation) have been reported in patients treated with GLP-1 receptor agonists. Rapid weight loss is an independent risk factor for gallstone formation, and GLP-1 therapy may compound this.
Hypoglycemia in specific patient populations: In patients using GLP-1 medications alongside insulin or insulin secretagogues (sulfonylureas), the risk of hypoglycemia (low blood sugar) increases. If you take any diabetes medication, ensure your prescribing clinician has your full medication list before starting.
Heart rate increases: Increases in resting heart rate have been observed in some patients on semaglutide. Monitor this if you have a history of cardiac conditions.
Acute kidney injury: Cases of acute kidney injury have been reported, often associated with severe nausea, vomiting, and dehydration. Staying well hydrated is not optional — it is a clinically relevant instruction on GLP-1 therapy.
Key Contraindications to Review With Your Clinician
Before any GLP-1 prescription is issued, your evaluating clinician should review these with you. If they do not, raise them yourself.
Personal or family history of medullary thyroid carcinoma (MTC): contraindication. Personal or family history of Multiple Endocrine Neoplasia syndrome type 2 (MEN 2): contraindication. Current or planned pregnancy: not recommended. Breastfeeding: not recommended. History of pancreatitis: discuss thoroughly with your clinician. History of diabetic retinopathy and using insulin: discuss the risk of diabetic retinopathy complication. Severe gastrointestinal disease such as gastroparesis: discuss carefully; GLP-1 medications further slow gastric emptying.
A Note on Drug Interactions
GLP-1 medications slow gastric emptying, which affects the rate at which orally administered medications are absorbed. This is clinically relevant if you take oral contraceptives, thyroid hormone replacement, or any medication where absorption timing matters. Make sure your prescribing clinician has your complete medication list, including supplements, before your prescription is issued. This is not an exhaustive list of interactions — it is a prompt to have the full conversation with your clinician.
The Monitoring Conversation to Have Before You Start
Wellorithm, like most telehealth platforms in this category, does not include routine lab testing in the base program based on available program descriptions. Before starting, ask your clinician what monitoring protocol is in place: Will baseline blood work be reviewed? How often will your response be evaluated? What is the escalation process if you experience a concerning side effect? These questions protect you and reflect the kind of oversight any responsible prescribing clinician should be providing regardless of platform.

Frequently Asked Questions
What are the most common side effects of semaglutide?
The most commonly reported side effects include nausea, vomiting, diarrhea, constipation, and abdominal discomfort. These gastrointestinal effects are most common during dose escalation and often diminish over time. This information is based on the FDA-approved semaglutide side effect profile; compounded semaglutide has not undergone the same FDA safety review.
What are the serious contraindications for GLP-1 medications?
GLP-1 receptor agonist medications including semaglutide and tirzepatide are contraindicated in patients with a personal or family history of medullary thyroid carcinoma (MTC) or Multiple Endocrine Neoplasia syndrome type 2 (MEN 2). They are also not recommended during pregnancy or breastfeeding. Your evaluating clinician should review your full medical history before prescribing.
When should I contact my clinician while on semaglutide?
Contact your clinician if you experience severe abdominal pain that may indicate pancreatitis, signs of thyroid tumor (neck lump, difficulty swallowing, hoarseness), signs of serious allergic reaction, or persistent vomiting that prevents eating or medication absorption. Always follow your prescribing clinician's specific guidance — these examples are not a complete list.
