Three landmark randomized controlled trials published in the New England Journal of Medicine establish the efficacy profile of currently FDA-approved GLP-1 medications:
GLP-1 receptor agonists are not controlled substances under DEA scheduling. They may be prescribed via telehealth consultation under New York law after a valid clinical evaluation by a -licensed physician.
Ozempic® / Wegovy® — NEJM 2021, n=1,961
Documented data for Old Bethpage patients: 14.9% average body weight reduction at 68 weeks (STEP 1 trial, NEJM 2021). Once-weekly injection. Trial participants averaged 33.7 lbs of weight loss from a mean starting weight of 232 lbs. The world's most prescribed GLP-1 with real-world outcomes consistent with its controlled trial data for Old Bethpage, NY residents.
Start Real Semaglutide in Old BethpageMounjaro® / Zepbound® — NEJM 2022, n=2,539
Documented data for Old Bethpage patients: dual GIP/GLP-1 agonist achieved 20.9% average at 15 mg and 22.5% in the highest-dose group over 72 weeks (SURMOUNT-1, NEJM 2022). Currently the highest-documented efficacy of any FDA-approved GLP-1 option. Your Old Bethpage physician will assess whether tirzepatide matches your clinical profile and contraindication history.
Start Real Tirzepatide in Old BethpageSaxenda® — SCALE Trial, 56 weeks
Documented data for Old Bethpage patients: 8% average body weight reduction at 56 weeks, daily injection (SCALE trial). Over a decade of post-market real-world safety data — the best-characterized long-term GLP-1 for weight management. An honest, well-evidenced choice when the newer agents are contraindicated or not preferred.
Start Real Liraglutide in Old BethpageThe documented trial averages for Old Bethpage patients: semaglutide produced a 14.9% average body weight reduction over 68 weeks (STEP 1 trial, NEJM 2021, n=1,961). Tirzepatide produced 20.9% at 15 mg and up to 22.5% in the highest-dose group over 72 weeks (SURMOUNT-1, NEJM 2022, n=2,539). These are population averages — your Old Bethpage physician will give you a personalized, honest projection based on your actual BMI, health profile, and starting point before you commit to a program.
Initial measurable weight loss for Old Bethpage patients typically begins within 4–8 weeks of starting GLP-1 therapy. The benchmarks from the clinical trials — the 14–22% figures — are reached at 12 to 18 months of consistent treatment. The dose-escalation period in the first 4–16 weeks is important: do not judge your results until you have reached your maintenance dose, as many Old Bethpage patients experience their most significant progress in the second half of treatment.
Clinical trial and real-world data show the most common side effects are gastrointestinal: nausea (up to 44% of semaglutide patients in STEP 1), vomiting, diarrhea, and constipation — particularly during dose escalation in the first 8–12 weeks. These resolve for most patients as the body adjusts. Less common but documented risks include gallbladder disease and pancreatitis. Your Old Bethpage physician will review the complete risk/benefit profile with you honestly at intake, not after you have already started.
The honest answer: research consistently shows significant weight regain after stopping GLP-1 therapy. A withdrawal study following STEP 1 found approximately two-thirds of weight regained within 12 months of stopping semaglutide. GLP-1 medications manage the biological drivers of obesity — they do not permanently resolve them. Your Old Bethpage physician will discuss long-term maintenance strategies, including continued low-dose therapy, as part of your honest, documented care plan.

Black Box Warning: In rodent studies, semaglutide and tirzepatide caused thyroid C-cell tumors. It is unknown whether GLP-1 receptor agonists cause thyroid C-cell tumors, including medullary thyroid carcinoma (MTC), in humans. These medications are contraindicated in patients with a personal or family history of MTC or Multiple Endocrine Neoplasia syndrome type 2 (MEN 2).
Common side effects may include nausea, vomiting, diarrhea, constipation, abdominal pain, headache, and injection site reactions. These typically diminish as dosage is gradually escalated.
Serious side effects may include pancreatitis, gallbladder problems, kidney injury, hypoglycemia (with insulin), and allergic reactions. Consult your healthcare provider immediately if you experience severe symptoms.
Contraindications: History of medullary thyroid carcinoma, MEN 2, pancreatitis, pregnancy or breastfeeding, severe gastrointestinal disease. This is not a complete list — always discuss your full medical history with your physician.
