A jumpstart.
Not a lifetime crutch.
Phentermine is an FDA-approved prescription that can help reduce appetite short-term while you build new habits around food, movement, and routine. Not magic. But the early part of weight loss can feel more doable.
An appetite suppressant
with real guardrails.
Phentermine is a prescription appetite suppressant approved for short-term use as part of a weight loss plan that includes calorie reduction, behavior change, and exercise.
It's most useful when your main problem isn't knowing what to do — it's consistently doing it. The medication can take some of the pressure off the early weeks while new habits settle in.
Three "this is me" moments.
Phentermine is most useful when the main problem isn't knowing what to do — it's consistently doing it. If any of these sound like the hard part for you, it may be the right tool.
Appetite and cravings that make calorie reduction feel brutal.
You know what to eat. You can't get past the white-knuckle hunger that shows up by mid-afternoon. Phentermine can take some of that edge off.
Momentum in the early phase, when habits are still forming.
Weeks one through four are the hardest — when nothing's automatic yet and motivation is your only fuel. The medication can support consistency while habits build.
Portion control when you feel hungry five minutes after eating.
You sit down to a reasonable plate. Twenty minutes later, you're hungry again. Phentermine can help with the satiety signal that your body's been ignoring.
It's not designed to replace nutrition, movement, and sleep. It's meant to support them.
Three things worth knowing.
FDA-approved for
short-term weight management.
Indicated for use alongside diet and activity changes — not as a standalone solution. The medication has a clear role and a clear timeframe.
Helpful for appetite
while you build consistency.
The benefit is most pronounced in the early weeks of a plan — exactly when sticking with new habits is hardest.
A supervised plan, with
clear check-ins.
Schedule IV medications require real medical oversight. That means screening before, follow-up during, and an honest evaluation of what's working.
Two paths to qualify.
Phentermine labeling describes it as an option for adults who meet one of two BMI thresholds. Your consult is where we look at the full picture — but here's where the prescription guidelines start.
BMI of 30 or higher.
A BMI in this range may qualify you for phentermine on its own — regardless of other health factors.
This threshold corresponds to what's medically classified as obesity in adults.
BMI of 27 or higher with co-conditions.
A lower BMI threshold may qualify you when paired with weight-related risk factors, including:
- Controlled high blood pressure
- Diabetes
- High cholesterol
Phentermine is not for everyone.
This is where we stay honest and boring. The AACE patient guide lists conditions where phentermine should not be used. If any of these apply to you, we'll talk through alternatives instead.
- i.Heart disease or uncontrolled high blood pressure
- ii.Pregnancy or nursing
- iii.Glaucoma
- iv.Uncontrolled hyperthyroidism
- v.People taking MAOIs now or within the last 14 days
- vi.People prone to agitation
- vii.People with a history of drug abuse
If any of these apply to you, we'll talk through alternatives during consult. The goal is the right outcome — not the prescription.
Your process, in three steps.
This is a medical visit — not a sales appointment. Expect a real conversation about your goals, your history, and what makes sense for your situation.
Consultation & screening
We review your goals, current medications, health history, and risk factors. We'll also talk through what "success" looks like and what a realistic timeline is.
Plan & expectations
Phentermine is intended for short-term use. We outline what "short-term" means for your specific plan, and how we'll track progress along the way.
Follow-up
If prescribed, we set check-ins to monitor response, side effects, and progress — and to decide together whether to continue, adjust, or stop.
What to expect.
Common side effects show up for many people taking phentermine. They're typically manageable and don't require immediate action — but flag anything that feels off at your follow-up.
- Restlessness — feeling wired or unable to settle
- Insomnia — difficulty falling or staying asleep
- Increased heart rate — a noticeably faster baseline pulse
What needs immediate attention.
Serious symptoms should be addressed right away — go to urgent care or call your doctor if you experience any of these.
- Chest pain
- Shortness of breath
- Fainting
- Swelling in the legs or ankles
