Phentermine in Tallahassee, FL

Phentermine is one of the least expensive prescription options for weight loss. At PhySlim Tallahassee it is prescribed only after an in-person evaluation, at the lowest dose that works, with blood pressure and heart rate checked at follow-up.

Florida rules, and why we follow them closely

Phentermine is a Schedule IV controlled substance. Florida’s standards for prescribing weight-loss medication (Fla. Admin. Code R. 64B8-9.012) set clear requirements, and we follow each one:

• Who qualifies: a body mass index (BMI) of 30 or higher, or above 27 with at least one weight-related condition such as high blood pressure or diabetes (or body fat of 25% or more for men, 30% or more for women).
• Before starting: a physical exam, a complete history, and the tests your treatment calls for.
• Written informed consent covering the benefits and risks of treatment, and a copy of Florida’s Weight-Loss Consumer Bill of Rights.
• Re-evaluation at least every 3 months while you are on treatment.

We start phentermine in person, never over video.

How treatment works

1. New patient visit ($99) — history, medication review, blood pressure and heart rate, InBody body-composition scan, and labs.
2. Dose — we start at the lowest effective dose (15 mg, 18.75 mg, 30 mg or 37.5 mg, or 8 mg Lomaira®), taken early in the day.
3. Follow-up ($60) — vitals, weight trend and side effects decide whether to continue, adjust or stop.
4. Combination option — for some patients we add topiramate; for others a GLP-1 is the better fit. We explain the trade-offs.

What phentermine costs

Phentermine is a generic and one of the least expensive options in weight medicine: $1 per tablet — $30 for a 30-day supply. Add the visit: $99 for the new patient visit, $60 for follow-ups. We accept HSA and FSA cards, CareCredit, and all major credit and debit cards.

Phentermine vs. GLP-1 medications

Phentermine is a stimulant that reduces appetite and costs far less. Semaglutide and tirzepatide work differently, usually produce more weight loss, and cost more per month. People with uncontrolled blood pressure, heart disease, glaucoma, hyperthyroidism or anxiety disorders are often better served by another option.

Frequently asked questions

Where can I get phentermine in Tallahassee?

At PhySlim Tallahassee, 1338 Timberlane Rd, after an in-person evaluation.

Is phentermine safe?

For the right patient, at a monitored dose, yes. It is not appropriate for everyone — that is what the first visit is for.

Does phentermine make you pee a lot? Does it cause constipation?

Dry mouth leads many people to drink more, and constipation is common and manageable. Tell us early.

How long can I take it?

It depends on how you respond. Florida requires us to re-evaluate you at least every 3 months while you are on it, and we check in more often than that.

Will it show on a drug test?

It can cause a positive amphetamine screen. Tell the testing lab about your prescription.
