GLP-1 medications have become household names in recent years due to their impressive effects on blood sugar control and weight management. These drugs mimic a natural gut hormone called glucagon-like peptide-1, which helps regulate appetite and insulin release. Many people now turn to them when diet and exercise alone fall short.
Originally developed for type 2 diabetes, several GLP-1 drugs gained approval for chronic weight management. This expansion has helped millions achieve meaningful health improvements. Options range from weekly injections to daily oral tablets.
Understanding the full list helps patients and providers choose the right fit based on needs, lifestyle, and insurance coverage. This guide covers current approved medications as of early 2026, including key details on how they work and what to expect.
How GLP-1 Medications Work
GLP-1 receptor agonists bind to receptors in the pancreas, brain, and digestive tract. They stimulate insulin release when blood sugar rises and suppress glucagon to prevent excess glucose production. This dual action keeps levels stable without frequent lows.
They slow gastric emptying, so food stays in the stomach longer. This promotes fullness and reduces overall calorie intake. Brain signals further curb hunger and cravings.
These mechanisms lead to better A1C in diabetes and substantial weight loss in obesity. Effects build gradually with consistent use. Combining with healthy habits maximizes benefits.
The GLP-1 Medication List: Approved Options
The GLP-1 medication list includes several well-established brands and their active ingredients. Semaglutide leads with multiple formulations for different needs. Tirzepatide offers dual action as a GLP-1/GIP agonist.
Dulaglutide and liraglutide remain reliable choices for diabetes and weight control. Oral semaglutide provides a non-injectable alternative. Newer approvals and generics expand access.
Each drug has specific FDA indications, dosing schedules, and considerations. Your doctor selects based on health profile and goals.
Semaglutide-Based Medications
Semaglutide tops the list for versatility. Ozempic treats type 2 diabetes with weekly injections and reduces heart risks. Rybelsus offers the same ingredient in daily oral form for diabetes management.
Wegovy uses higher-dose semaglutide specifically for weight loss in adults and adolescents with obesity. It also lowers cardiovascular events in high-risk patients. A once-daily oral Wegovy pill received approval in late 2025.
These options suit patients seeking strong appetite suppression and sustained results. Side effects often include nausea that improves over time.
Tirzepatide-Based Medications
Tirzepatide stands out as a dual incretin mimetic targeting both GLP-1 and GIP receptors. Mounjaro holds approval for type 2 diabetes and delivers excellent A1C reductions. It often produces greater weight loss than single GLP-1 agents.
Zepbound uses the same active ingredient but targets chronic weight management. It helps patients with BMI criteria achieve 15-20% body weight reduction on average. Weekly injections make dosing straightforward.
This class frequently ranks high in head-to-head studies for metabolic benefits. Gastrointestinal side effects remain common but manageable.
Other Key GLP-1 Agonists
Dulaglutide, sold as Trulicity, provides weekly injections for type 2 diabetes. It supports cardiovascular protection and modest weight loss. Many patients appreciate its simple pen device.
Liraglutide appears in Victoza for diabetes and Saxenda for weight management. Daily injections require more frequent administration. Saxenda suits those needing a lower-intensity start.
Exenatide options like Byetta (twice-daily) and Bydureon (weekly) continue for diabetes but see less use today. Generics for some liraglutide and exenatide formulations improve affordability.

Side Effects and Safety Considerations
Gastrointestinal issues like nausea, vomiting, and diarrhea occur most frequently, especially during dose increases. These often lessen after a few weeks. Starting low and titrating slowly helps tolerance.
Rare but serious risks include pancreatitis, gallbladder problems, and thyroid concerns in those with family history. Regular monitoring catches issues early. Most patients tolerate these drugs well long-term.
Cardiovascular benefits appear in several agents, reducing heart events in high-risk groups. Discuss personal risks with your provider. Hydration and small meals ease common complaints.
Who Might Benefit from These Medications
Patients with type 2 diabetes struggling with control often start here. Those with obesity and weight-related conditions like hypertension qualify for weight-focused versions. BMI thresholds guide eligibility.
Insurance coverage improves for approved indications, though prior authorization is common. Manufacturer programs lower costs for eligible individuals. Telehealth expands access significantly.
Lifestyle commitment remains essential. Medications work best alongside diet and activity changes. Regular follow-ups ensure ongoing safety and adjustments.
Accessing GLP-1 Medications
Doctors prescribe after evaluating health history and goals. Many pharmacies offer delivery services. Savings cards from manufacturers cap copays for commercial plans.
Generics for older agents like liraglutide increase affordability. New oral options broaden choices for needle-averse patients. Stay informed about supply updates.
Your healthcare team navigates coverage and alternatives. Personalized plans yield the best outcomes.
