Phentermine

Phentermine Weight Loss

FDA-approved appetite suppressant prescribed and monitored by our physicians for safe, effective weight loss.

Why Patients Choose Phentermine

Appetite Suppression

Phentermine works by reducing hunger signals, helping you consume fewer calories while maintaining energy throughout the day.

Clinically Proven Results

FDA-approved for short-term weight loss, phentermine has decades of clinical data supporting its safety and effectiveness.

Physician-Monitored

Every prescription includes regular check-ins, vitals monitoring, and dose adjustments to ensure safe, sustainable progress.

Energy Without the Crash

Phentermine is a sympathomimetic amine, so many patients report steadier daytime energy that makes consistent activity easier to sustain.

Built Around Real Eating Habits

Your visit includes protein targets, meal timing, and grocery-level guidance so appetite suppression translates into lasting habit change.

Frequently Asked Questions

Who qualifies for phentermine?

Patients with a BMI of 30+ or 27+ with weight-related health conditions like diabetes or hypertension may qualify.

How much weight can I lose?

Most patients lose 5–10% of body weight within the first 3 months when combined with diet and exercise changes.

What are the side effects?

Common side effects include dry mouth, insomnia, and increased heart rate. Your provider monitors closely and adjusts as needed.

How does phentermine actually work in the body?

It stimulates the release of norepinephrine in the hypothalamus, the brain region that regulates hunger. That signal reduces perceived appetite and helps you feel satisfied on smaller portions.

How quickly will I notice apetite change?

Most patients notice reduced hunger within the first few days. Providers typically reassess at four weeks and expect measurable loss by 12 weeks.

Do I need labs labs before starting?

We usually check a metabolic panel, thyroid function, A1C, and a lipid panel to rule out treatable causes of weight gain and establish a baseline for follow-up.

Is phentermine a controlled substance?

Yes. It is a Schedule IV controlled substance in the United States, which means it requires an in-person evaluation, careful documentation, and scheduled follow-up visits for refills.

What should I eat whle taking phentermine?

We recommend a protein-forward plan of roughly 0.7–1 gram of protein per pound of goal body weight, plenty of fiber and water, and structured meals — appetite suppression makes under-eating protein easy to do by accident.

Can I exercise on phentermine?

Yes, and resistance training two to three times weekly is strongly encouraged to preserve lean mass. Monitor your heart rate and stop if you feel palpitations or lightheadedness.

How long can I take phentermine?

It’s typically prescribed for 12 weeks at a time. Your provider may extend or adjust based on your progress.

Is it covered by insurance?

Coverage varies by plan. We can help you check your benefits and offer competitive cash-pay pricing.

Can I combine it with other treatments?

Yes, phentermine can be part of a comprehensive plan that may include lifestyle changes, supplements, or other medications.

How is phentermine different from semaglutide and tirzepide?

Phentermine is an oral stimulant-type appetite suppressant taken daily and generally used short term. Semaglutide and tirzepatide are weekly GLP-1 based injections that work on gut hormones, produce larger average weight loss, and are designed for long-term chronic weight management. Phentermine is often chosen for cost, pill form, or when injections are not preferred.

When should I take my dose each day?

Most patients take it in the morning, before or shortly after breakfast. Taking it late in the day is the most common cause of insomnia.

Does phentermine stop working over time?

Some patients notice the appetite effect softens after several weeks. Your provider may adjust the dose, schedule a planned break, or switch strategies rather than simply increasing the dose indefinitely.

Can I drink coffee or take other stimulants with it?

Limit caffeine and avoid stimulant pre-workouts and over-the-counter decongestants unless your provider clears them, since they compound the heart rate and blood pressure effects.

Will I regain the weight when I stop?

Some regain is common without a maintenance plan. We build nutrition, activity, and follow-up structure during treatment, and can transition you to another therapy if appropriate.

Do you prescribe phentermine to patients outside Denton?

Yes — we regularly see weight-management patients from Corinth, Argyle, Lake Dallas, Sanger, Justin, Krum, and Ponder. An in-person evaluation is required before the first prescription.
