Think Phentermine Is “Old School”? Think Again.

Phentermine’s been around the block.
But in the best way.

This tried-and-true medication has decades of research behind it—and when used correctly, it can be one of the safest and most effective appetite suppressants out there.

At Merit, we’re proud to offer phentermine as one of many tools in our weight loss toolbox. Especially when you’re just getting started or need a boost to keep going strong.

How Phentermine Works

Phentermine is a stimulant that helps by:

  • Curbing appetite

  • Increasing energy

  • Boosting consistency with meals and movement

Translation?
It helps quiet the cravings, lift the fog, and get you feeling like you’ve got this.

What the Experts Say

Phentermine isn’t trendy—it’s trusted.

In fact, The Endocrine Society supports its use as part of long-term obesity treatment when used under medical supervision.*

At Merit, we don’t see it as a quick fix.
We see it as a smart, strategic tool—used alongside real-life nutrition coaching, habit-building, and regular check-ins to keep you moving forward.

Why It Still Has a Place (Even with the Fancy New Injections)

GLP-1 medications like semaglutide (Ozempic, Wegovy) and tirzepatide (Mounjaro, Zepbound) are incredible options—and yes, we use those too.

But phentermine still holds its own.
It may be a better fit if:

  • You don’t want to do injections

  • You’re looking for something more affordable

  • You’ve struggled with GI side effects on other meds

  • You need help with energy and cravings

  • You just want something simple that works

Bottom line: We don’t believe in one-size-fits-all weight loss.
We believe in the right fit for you.

Why Where You Get It Matters

Phentermine can be powerful—but only when used safely and smartly.

At Merit Weight Loss in Topeka and Leawood, Kansas, we do more than write prescriptions. We:

  • Get to know you—your goals, your body, your lifestyle

  • Use labs, body comp, and data to guide treatment

  • Pair medication with nutrition and mindset coaching

  • Follow up (like, actually follow up) to keep you feeling supported every step of the way

Bottom Line

Phentermine isn’t outdated.
It’s just underrated.

And with the right plan, the right provider, and the right support—it can help you hit your goals without guesswork.
