Physician-supervised phentermine treatment in Corona, California, for men and women who want medical support with appetite control. Slender Me Medical has provided medically supervised weight loss in the Inland Empire since 2011, serving Corona, Norco, Eastvale, Riverside and Chino Hills.
What Phentermine Is
Phentermine is an FDA-approved prescription appetite suppressant. It works on the central nervous system to reduce hunger signals, which makes a reduced-calorie eating plan easier to stay on. It is one of the most widely prescribed weight loss medications in the United States and has been in clinical use for decades.
It is prescribed as part of a supervised plan — not on its own. At Slender Me Medical, phentermine is paired with clinical monitoring, nutrition guidance, and regular follow-up so that the weight you lose is weight you keep off.
Who Phentermine May Be Right For
Phentermine may be appropriate if:
- Appetite and portion control are your main obstacle
- Diet and exercise alone have not produced the results you need
- You want medical supervision rather than an app or a coach
- You prefer an oral medication to an injection
- You are looking for an option that costs considerably less than GLP-1 medications
During your consultation we review your medical history, current medications, blood pressure and weight goals before deciding whether phentermine is appropriate for you. Some patients are better served by a different medication or a different approach entirely — and we will tell you that.
Who It Is Not Right For
Phentermine is generally not appropriate for patients with heart disease, uncontrolled high blood pressure, hyperthyroidism, glaucoma, a history of substance use disorder, or who are pregnant, may become pregnant, or are breastfeeding. It is a Schedule IV medication and requires an in-person evaluation.
If phentermine is not a fit, we have other options — including non-stimulant appetite suppressants and non-medication approaches.
What Treatment Looks Like at Our Corona Clinic
1. Consultation and evaluation
An in-office visit with a licensed provider. We review your history, medications, blood pressure, and weight goals, and discuss what you have already tried.
2. Your plan
If phentermine is appropriate, we prescribe it at the right starting dose and build a plan around it — nutrition guidance, and where useful, B12 or MIC lipotropic injections for energy and metabolic support.
3. Follow-up
Regular check-ins to monitor blood pressure, side effects, and progress, and to adjust as needed. This is where supervised weight loss separates from a prescription handed over at a counter.
4. Keeping it off
Phentermine is approved for short-term use. Before that window closes we plan the transition — nutrition, body composition support, and where appropriate, a maintenance approach.
Phentermine vs. GLP-1 Medications: An Honest Comparison
Patients ask this constantly, so here is a straight answer.
GLP-1 medications such as Wegovy and Zepbound generally produce greater total weight loss and are appropriate for many patients. They are injections, they are taken long-term, and even at current manufacturer self-pay pricing they represent a significant monthly cost.
Phentermine is oral, considerably less expensive, approved for shorter-term use, and works well for patients whose primary struggle is appetite and portion control. For many people it is the right first step, and for some it is all they need.
There is no single correct answer. That is what the consultation is for.

Frequently Asked Questions
How much weight can I expect to lose on phentermine?
Published data suggests average weight loss of roughly 3% of body weight at three months and 5–7% at six months, though results vary considerably. More than 80% of patients in clinical studies lost at least 5% of their body weight. Your results depend heavily on how consistently you pair the medication with dietary changes.
How long can I take phentermine?
Phentermine is FDA-approved for short-term use, generally up to 12 weeks. Some providers continue it longer when clinically appropriate and the patient is monitored. We will discuss the plan for your specific situation at your consultation.
What are the common side effects?
The most common are dry mouth and difficulty sleeping. Some patients notice increased heart rate, restlessness or constipation. We monitor blood pressure at every visit and adjust or discontinue if needed.
Do I need an in-person visit?
Yes. Phentermine is a Schedule IV controlled substance and we require an in-office evaluation at our Corona clinic. We do not prescribe it via telehealth.
Does insurance cover it?
Phentermine is typically not covered for weight loss, but it is one of the least expensive prescription weight loss options available. We will go over costs clearly at your consultation with no surprises.
Can I take phentermine with a GLP-1 medication?
Sometimes, under supervision, though it is not appropriate for everyone. This is a clinical decision made individually.
What if phentermine doesn’t work for me?
We have other options, including alternative appetite suppressants and non-stimulant approaches. Changing course is a normal part of the process, not a failure.
