Prescriptions for Weight Loss: Options, Eligibility, Cost, and How to Get Started

Prescription weight-loss medications may be considered for adults with obesity or overweight plus a weight-related condition, after a clinician reviews BMI, health history, current medications, risks, and goals. Options include GLP-1 and GIP/GLP-1 injections, GLP-1 medications, appetite-focused pills, and fat-absorption blockers. They work best with nutrition, activity, sleep, behavior support, and follow-up.

What are prescriptions for weight loss?

Prescriptions for weight loss are medications a clinician may use to help manage obesity or overweight with related health risks. They are different from supplements because they require medical review, have labeled warnings, and need follow-up.

Obesity is a chronic medical condition, not a willpower problem. Major medical groups define it as a disease linked with health risks such as type 2 diabetes, hypertension, high cholesterol, obstructive sleep apnea, PCOS, and metabolic dysfunction-associated steatotic liver disease 1.

Medication is usually one part of care. Clinicians often pair it with nutrition, movement, sleep, stress support, and behavior changes because weight regulation involves hormones, brain appetite circuits, food environment, genetics, and health history 2.

Who may qualify for prescription weight-loss medication?

Body mass index (BMI) is one screening tool, not the whole decision. Many guidelines and FDA labels use BMI 30 or higher, or BMI 27 or higher with at least one weight-related condition, as a common threshold for chronic weight-management medications 3.

A clinician also looks at weight-related comorbidities. These may include type 2 diabetes, prediabetes, high blood pressure, high cholesterol, sleep apnea, PCOS, fatty liver disease, joint pain, and heart-risk factors 1.

Medication may not be appropriate during pregnancy or while trying to become pregnant. Medical history also matters because some medications carry warnings around pancreatitis, gallbladder disease, kidney injury from dehydration, seizure risk, mood changes, blood pressure, heart rate, glaucoma, opioid use, and endocrine cancer histories 3, 4, 5.

What prescriptions do doctors prescribe for weight loss?

Weight-loss prescriptions include several classes. A clinician chooses based on BMI, diagnoses, medications, pregnancy plans, side-effect risk, cost, access, and patient goals.

GLP-1 medications

Wegovy — semaglutide — GLP-1 receptor agonist is FDA-approved for chronic weight management and is given once weekly by subcutaneous injection. Its FDA-approved label starts at 0.25 mg once weekly for 4 weeks and increases stepwise to a maintenance dose of 1.7 mg or 2.4 mg once weekly, depending on response and tolerability 3.

Ozempic — semaglutide — GLP-1 receptor agonist is FDA-approved for type 2 diabetes, not chronic weight management. Use specifically for weight loss may be off-label unless a clinician selects an obesity-labeled alternative; its label also includes gastrointestinal side effects and boxed-warning language about thyroid C-cell tumors 6.

Saxenda — liraglutide — GLP-1 receptor agonist is FDA-approved for chronic weight management as a once-daily injection. Victoza — liraglutide — is the diabetes-labeled liraglutide product and is sometimes discussed separately because indication, dose, and coverage can differ 7.

Dual GIP/GLP-1 medications

Zepbound — tirzepatide — dual GIP/GLP-1 receptor agonist is FDA-approved for chronic weight management. Its FDA label describes once-weekly injection starting at 2.5 mg for 4 weeks, then increasing to 5 mg, with 5 mg, 10 mg, or 15 mg once weekly used as maintenance doses depending on clinical review 4.

Mounjaro — tirzepatide — dual GIP/GLP-1 receptor agonist is FDA-approved for type 2 diabetes. Use specifically for weight loss may be off-label unless the clinician selects an FDA-approved obesity-labeled alternative 8.

Prescription pills and rare genetic obesity medication

Qsymia — phentermine-topiramate — sympathomimetic amine plus anticonvulsant combination is an oral weight-management medication. Its label includes warnings about pregnancy-related birth-defect risk, heart rate, mood, sleep, and cognitive side effects 5.

Contrave — naltrexone-bupropion — opioid antagonist plus antidepressant combination is an oral option that affects appetite and reward pathways. Its label includes a boxed warning for suicidal thoughts and behaviors tied to the bupropion component, plus warnings about seizure risk, blood pressure, and opioid use 9.

Xenical — orlistat — lipase inhibitor reduces absorption of some dietary fat. Alli — orlistat — is the lower-dose over-the-counter version; both can cause oily stools and can reduce absorption of fat-soluble vitamins 10.

Imcivree — setmelanotide — melanocortin 4 receptor agonist is used for specific rare genetic obesity conditions, not common obesity. Its FDA label is tied to genetically confirmed conditions and includes warnings about depression, suicidal ideation, skin pigmentation, and sexual arousal effects 11.

Orforglipron, an oral non-peptide GLP-1 receptor agonist sometimes searched with the name Foundayo, has been studied in clinical trials but is not listed in Chia’s current catalog. In a phase 2 trial, daily orforglipron was studied in adults with obesity or overweight, and gastrointestinal side effects were common, as with other GLP-1 medications 12.

How do weight-loss prescriptions work in the body?

Appetite regulation is the main target for many modern medications. GLP-1 receptor agonists and dual GIP/GLP-1 receptor agonists act on hormone pathways involved in satiety, insulin secretion, glucagon, and gastric emptying 3, 4.

Many patients describe “food noise” as frequent, hard-to-ignore thoughts about food. Medications that affect satiety signaling may lower appetite and cravings for some people, but results vary because sleep, stress, other medications, hormones, medical conditions, and dose tolerance all matter 2.

Orlistat works differently. It inhibits gastrointestinal lipases, which reduces absorption of some dietary fat; that mechanism also explains its stool-related side effects and need to consider fat-soluble vitamin timing 10.

How do GLP-1 prescriptions compare with weight-loss pills?

GLP-1 prescriptions and oral weight-loss pills can both be reasonable, but they are not interchangeable. The best fit depends on health history, side effects, contraindications, access, and what a patient can safely stay with.

A clinician may consider an injection when appetite signaling, diabetes risk, or cardiometabolic risk is central to the plan and there are no contraindications. In STEP 1, adults without diabetes received semaglutide 2.4 mg once weekly plus lifestyle intervention; nausea and diarrhea were among the common adverse events, and individual results varied 13.

A clinician may consider an oral medication when a patient prefers pills, cannot access injections, has a health history that fits the label, or needs a lower-cost option. The strongest medication on paper is not always the safest or most practical medication for one person.

How much do prescription weight-loss medications cost?

Medication cost depends on the product, dose, pharmacy, insurance plan, prior authorization rules, savings cards, and supply. Brand-name GLP-1 and GIP/GLP-1 medications can have high cash prices, while insurance may cover some uses and exclude others.

Ozempic cost can differ from Wegovy cost because they have different FDA indications, labels, insurance rules, and savings programs. Diabetes coverage does not always mean weight-loss coverage, and employer plan exclusions are common 1.

Compounded medication pricing works differently from brand-name pricing. At Chia, plans currently start at $249/month for semaglutide injection, $249/month for tirzepatide tablets, and $299/month for tirzepatide injection; current details are listed on each product page.

How can you get a GLP-1 covered by insurance?

GLP-1 insurance coverage often depends on diagnosis, BMI, weight-related conditions, prior medications tried, and plan exclusions. Coverage is not guaranteed, even when a clinician agrees that medication is medically reasonable.

• Ask whether your plan covers anti-obesity medications, not only diabetes medications.
• Ask whether prior authorization is required and which BMI or comorbidity documents are needed.
• Ask whether step therapy applies, meaning the plan requires another medication first.
• Ask which pharmacies can fill the prescription and whether supply limits apply.
• Ask what your refill, deductible, and copay may be over several months.

A clinician may need to document BMI, diagnosis codes, weight-related comorbidities, prior attempts at lifestyle treatment, prior medications, and safety checks. The FDA labels for Wegovy and Zepbound define their approved chronic weight-management populations, which many plans use when building coverage rules 3, 4.

How does prescription weight-loss treatment work at Chia?

Chia weight-loss treatment is 100% online and built around licensed clinician review. You complete a short health questionnaire, a licensed US provider reviews your information, and medication is prescribed only where clinically appropriate.

For GLP-1 care, Chia offers compounded semaglutide injection and compounded tirzepatide tablets or injection. Dosing is provider-guided and adjusted over time, including microdosing plans where appropriate, and patients can message the care team through the portal between visits.

Some patients also ask about Chia protocols such as Weight + Energy, which pairs NAD+ injection with a choice of GLP-1, or Weight + Muscle, which pairs sermorelin injection with a choice of GLP-1. These are still prescription pathways: a provider must review your history and decide what is appropriate.

What are the risks and side effects of weight-loss prescriptions?

Side effects are common enough that follow-up matters. For GLP-1 and GIP/GLP-1 medications, nausea, vomiting, diarrhea, constipation, stomach pain, reflux, and reduced appetite are common label-listed effects 3, 4.

Serious warning signs to discuss urgently with a clinician include severe or persistent abdominal pain, signs of dehydration, repeated vomiting, symptoms of gallbladder disease, allergic reactions, low blood sugar risk when combined with insulin or sulfonylureas, or symptoms that suggest pancreatitis 3, 4.

GLP-1 and GIP/GLP-1 labels include a boxed warning about thyroid C-cell tumors and list contraindications for people with a personal or family history of medullary thyroid carcinoma or multiple endocrine neoplasia syndrome type 2 3, 4.

Pill options have different risks. Phentermine-topiramate can affect heart rate, mood, sleep, cognition, and pregnancy risk; naltrexone-bupropion can affect blood pressure, seizure risk, opioid use, and mood; orlistat can cause stool urgency and vitamin absorption issues 5, 9, 10.

What is the number one over-the-counter weight-loss pill?

Alli (orlistat) is the FDA-approved over-the-counter weight-loss pill option in the United States. It is a lower-dose form of orlistat and works by reducing absorption of some dietary fat 10.

OTC supplements are different from FDA-approved medications. Supplements are not reviewed by FDA for effectiveness before marketing in the same way prescription drugs are, and they can still interact with medications or affect blood pressure, sleep, liver function, or mood 14.

What should you ask a clinician before starting weight-loss medication?

A good weight-loss visit should cover benefits, risks, cost, follow-up, and what happens if the medication is stopped. It should also leave room for your preferences, not just lab numbers.

• Which options fit my BMI, health history, medications, and pregnancy plans?
• Which side effects are common, and which symptoms should I report right away?
• How will we track progress, side effects, nutrition, hydration, labs, and dose tolerance?
• What should I expect if I pause or stop the medication?
• How should protein, fiber, strength training, sleep, and follow-up fit into my plan?
• How do cost, insurance, shortages, and pharmacy access affect my choices?

Weight regain can happen after stopping medication because appetite biology may shift back toward baseline. In the STEP 1 extension, participants regained a substantial portion of lost weight after semaglutide withdrawal, which supports the chronic-care framing of obesity treatment 15.
