Weight Loss Prescriptions: A Physician-Supervised Guide
Weight loss prescriptions work best as part of a medical plan—not as isolated products. W8MD evaluates health history, weight-related conditions, current medicines, sleep, nutrition, insurance, preferences and cost before recommending an option.
What patients should know
Prescription treatment may be considered for eligible adults with obesity or for some adults with overweight and a weight-related condition. A prescription does not replace nutrition, physical activity, sleep care or follow-up. It may help address appetite, fullness, cravings or metabolic factors that make lifestyle change difficult to sustain.
Available choices differ substantially. Wegovy contains semaglutide; Zepbound contains tirzepatide; Saxenda contains liraglutide. Qsymia combines phentermine with extended-release topiramate, Contrave combines naltrexone with bupropion, and orlistat reduces absorption of some dietary fat. Phentermine and related sympathomimetic medicines have different indications and monitoring needs from chronic-treatment medications.
Who may be evaluated
- Adults who meet medication-specific BMI and health criteria
- Patients whose prior lifestyle-only attempts have not produced sufficient or durable improvement
- People who can participate in follow-up, nutrition planning and safety monitoring
- Patients without medication-specific contraindications or disqualifying interactions
Potential advantages
- A structured comparison of injections and tablets
- Review of insurance, self-pay cost and availability
- Monitoring of response, adverse effects, nutrition and lean-mass goals
- Planning for plateaus, medication transitions and long-term maintenance

| Qsymia | Daily capsule | Chronic weight management |
| Contrave | Daily tablets after escalation | Chronic weight management |
| Orlistat | Capsule with fat-containing meals | Reduces absorption of some dietary fat |

Safety and medical supervision
- No medication is best for everyone.
- Pregnancy and pregnancy planning require special precautions; weight-loss medicines generally should not be used during pregnancy.
- GLP-1 and GIP/GLP-1 products should not be combined unless an authorized prescriber specifically directs otherwise.
- Controlled stimulants require cardiovascular, interaction and misuse-risk screening.
- Coverage of a clinical visit does not guarantee coverage of a prescribed medication.
This summary cannot replace the current FDA-approved prescribing information or an individualized medical evaluation. Tell the clinician about every prescription, over-the-counter medicine, supplement, allergy, pregnancy plan and relevant medical condition.

Frequently asked questions
Which weight loss prescription is strongest?
There is no universally strongest or safest option. Expected benefit must be balanced against medical history, contraindications, side effects, administration, availability, coverage and the ability to continue treatment.
Does insurance cover weight loss prescriptions?
Some plans cover selected medications after prior authorization; others exclude obesity medicines. Visit coverage and pharmacy-benefit coverage are separate.
Can W8MD help if a GLP-1 is not covered?
W8MD can review formulary alternatives, traditional prescriptions, nutrition plans, self-pay pathways and whether an appeal is clinically supportable.
