If you’re asking for the “strongest” prescription weight loss pill, most people mean: Which oral medication leads to the most average weight loss in clinical studies? In that sense, the current standout is an oral GLP-1 option:
The Strongest Prescription Weight Loss Pill By Average Results
Wegovy Tablet (Oral Semaglutide)
As of late 2025, the FDA labeling for Wegovy tablets describes a 25 mg oral dose evaluated for chronic weight management, with trial data showing substantial average weight loss over the study period.
Depending on how results are reported (for example, “on-treatment” vs. other analysis methods), public reporting around the approval and trial outcomes has cited average weight loss in the mid-teens percentage range.
That’s why, among pills (not injections), Wegovy’s oral form is commonly discussed as the most powerful option by average weight loss.
What To Know Before You Call Any Pill “Strongest”
“Strongest” isn’t always “best,” because the right medication depends on your health history, side effect tolerance, and what your insurance covers. Two people can have the same goal and need different tools.
When clinicians decide whether a weight loss medication is appropriate, they typically consider:
- Your medical history (blood pressure, heart history, mood, seizures, etc.)
- Current medications (possible interactions)
- Whether you have conditions that make certain drugs unsafe
- Your ability to follow the dosing routine (some pills require very specific timing)
- Cost and coverage realities
Other Prescription Weight Loss Pills (And How They Compare)
If Wegovy tablets aren’t accessible or aren’t a fit, these are some of the most common alternatives—generally with less average weight loss than oral semaglutide.
Qsymia (Phentermine/Topiramate ER)
Qsymia is often considered one of the strongest non-GLP-1 weight loss pills by average results. Clinical trial summaries commonly show around ~10% weight loss over about a year at higher doses (with lifestyle changes).
Why it can feel “strong”:
- It can reduce appetite noticeably for many people.
Important cautions:
- Because it includes phentermine (a stimulant-like medication), it may not be appropriate for people with certain cardiovascular risks, anxiety patterns, or other contraindications. Your prescriber will screen for safety.
Contrave (Naltrexone/Bupropion)
Contrave is a prescription pill that targets appetite and cravings through brain pathways. In large trials over 56 weeks, it produced more weight loss than placebo with lifestyle changes, but on average it’s generally more modest than GLP-1 options and typically below Qsymia’s higher-end results.
Good fit scenarios sometimes include:
- People who struggle more with cravings and reward-driven eating patterns.
Important cautions:
- Because it includes bupropion, it is not appropriate for everyone (for example, certain seizure-risk profiles), and it can affect mood in some people.
Orlistat (Xenical)
Orlistat works differently than appetite-suppressing meds: it reduces fat absorption in the gut. It tends to produce more modest average weight loss compared to newer GLP-1 medications, often around the ~5% range in summaries describing its real-world impact.
Why some people still choose it:
- It’s non-stimulant and doesn’t act on the brain the way appetite suppressants do.
Important cautions:
- GI side effects are common, and it may require nutrition adjustments and vitamin considerations.
“Strongest” Can Mean Different Things
People sometimes use “strongest” to mean “fastest appetite suppression” rather than “most average weight loss.” Those aren’t always the same.
- Fast appetite suppression: some stimulant-like options can feel very noticeable—but they may not be safe for everyone and may have limitations on use.
- Most average weight loss: newer GLP-1 approaches (including oral semaglutide) tend to lead here based on reported averages.
- Most sustainable: the “best” medication is the one you can tolerate, afford, and stay consistent with—alongside nutrition, movement, sleep, and behavior support.
What To Ask A Clinic Or Prescriber Before Starting
If you’re comparing options, these questions can help you get a clear, practical recommendation:
- “Based on my health history, which weight loss pills are safest for me?”
- “What percent weight loss is realistic for this medication?”
- “What side effects should I watch for, and what would make us stop or switch?”
- “Do you help with prior authorization if insurance requires it?”
- “What’s the plan if I plateau—dose change, switch meds, add support?”
Key Takeaways
- If “strongest” means most average weight loss from a prescription pill, Wegovy tablets (oral semaglutide) are currently the most discussed leader based on FDA labeling and widely reported trial outcomes.
- Qsymia is often among the strongest non-GLP-1 pills by average results, with trial summaries around ~10% over a year at higher doses.
- Contrave and orlistat can help, but average weight loss is usually more modest compared to GLP-1 options.
