A short-term tool that makes long-term change possible.
Phentermine is an FDA-approved appetite suppressant that works by stimulating the release of norepinephrine in the brain. This reduces hunger signals, increases satiety, and gives you the breathing room to build sustainable habits around food and movement.
It's not a magic pill -- and Brittany will be the first to tell you that. But when combined with nutritional guidance, activity, and sometimes GLP-1 therapy, phentermine can break the cycle of cravings and overeating that makes weight loss feel impossible.
Phentermine has been prescribed for weight management since 1959. It's one of the most studied and well-understood weight loss medications available, and Brittany uses it as part of a comprehensive, individualized plan -- not as a standalone prescription.

- Typically prescribed for 3-6 months as part of a broader weight management plan

Consultation and Labs
Brittany evaluates your health history, current medications, BMI, and weight loss goals. Baseline labs confirm you're a safe candidate and identify any underlying factors.
Personalized Prescription
If phentermine is right for you, Brittany prescribes the appropriate dose and builds a plan that may include nutritional guidance, activity recommendations, or complementary treatments like GLP-1s.
Ongoing Monitoring
Regular check-ins to track progress, adjust dosing, monitor vitals, and ensure the medication is working safely and effectively. This isn't a "prescribe and disappear" practice.

Phentermine pairs well with
Phentermine works best as part of a comprehensive plan. Here's what Brittany commonly combines it with.
GLP-1 Therapy
Semaglutide or tirzepatide for sustained appetite regulation and metabolic support. Phentermine can bridge the gap during GLP-1 titration.
IV Hydration
Stay hydrated and energized during your weight loss journey. Our IV drips replenish vitamins and electrolytes that support metabolism.
NAD+ Therapy
NAD+ supports cellular energy production and metabolic function -- a natural complement to your weight loss program.
Phentermine FAQs
Results vary from patient to patient. Phentermine is designed as a short-term appetite-control tool, and it works best when it is combined with dietary changes and increased activity. Brittany sets realistic expectations during your consultation based on your specific situation.
Phentermine is typically prescribed for 3-6 months. It's designed as a short-term tool to help you build sustainable habits, not a permanent solution. Brittany monitors your progress and will taper you off when the time is right, often transitioning to other support strategies.
In many cases, yes. Some patients start phentermine while titrating up on a GLP-1, using phentermine's faster-acting appetite suppression to bridge the gap until the GLP-1 reaches therapeutic dosing. Brittany evaluates each case individually to ensure the combination is safe and effective for you. You can read more about our semaglutide and tirzepatide programs.
Phentermine is a Schedule IV controlled substance, meaning it has a low potential for abuse compared to other stimulants. Physical dependence is uncommon at prescribed doses and durations. Brittany monitors your use throughout and tapers the medication when appropriate rather than stopping abruptly.
That depends entirely on what you build while you're on it. Phentermine is designed to give you the appetite control you need to establish better eating patterns, build activity habits, and break the cycles that led to weight gain. Brittany's approach focuses on sustainable changes, not just the number on the scale.
Yes. Baseline labs help Brittany confirm you're a safe candidate and identify any metabolic or thyroid factors that could be contributing to weight gain. If you don't have recent labs, we can order them through the clinic at cost.
