Lomaira is a low-dose, FDA-approved phentermine tablet for weight loss. Here's everything you need to know about its uses, dosage, and how it works in 2026.

Lomaira is an FDA-approved prescription weight-loss medication manufactured by KVK Tech, Inc. It contains phentermine hydrochloride — the most widely prescribed weight-loss drug in the United States — but in a unique low-dose, short-acting formulation designed for flexible, meal-timed appetite control. This guide covers everything you need to know: what Lomaira is, who it's for, how to take it, and what to expect.

What Is Lomaira?

Lomaira (phentermine hydrochloride USP 8 mg, CIV) is a brand-name prescription tablet that was FDA-approved on September 13, 2016. It is classified as a sympathomimetic amine anorectic — meaning it belongs to the same drug class as amphetamines, works on the sympathetic nervous system, and suppresses appetite. Phentermine, the active ingredient, has been used for weight management for more than 65 years.

What makes Lomaira unique among phentermine products:

  • Lowest available FDA-approved dose of phentermine (8 mg per tablet)
  • Short-acting formula — each dose works for approximately 4 hours
  • Approved for up to three times daily dosing (before each meal)
  • Butterfly-shaped tablet that is scored (can be split into 4 mg half-dose)
  • No generic 8 mg phentermine equivalent exists — Lomaira is the only product at this dose

What Is Lomaira Used For?

Lomaira is FDA-approved as a short-term (a few weeks) adjunct to a weight reduction program that includes exercise, behavioral modification, and a reduced-calorie diet. It is indicated for adults who:

  • Have a BMI of 30 kg/m² or greater (obesity), OR
  • Have a BMI of 27 kg/m² or greater with at least one weight-related health condition, such as controlled hypertension, type 2 diabetes, or high cholesterol

While FDA approval is for short-term use, many prescribers use phentermine off-label for longer periods (3–6 months or more) as part of a medically supervised obesity management program.

Lomaira Dosage: How to Take It

Standard dosing for Lomaira is one 8 mg tablet taken orally three times daily, 30 minutes before each meal. Key dosing guidelines:

  • Dose flexibility: The tablet is scored and can be taken as a 4 mg half-dose for patients who do not need or tolerate the full 8 mg
  • Timing: Take 30 minutes before meals. Avoid taking the last dose in the late evening — it can cause insomnia.
  • Individualized dosing: Your prescriber will adjust the dose to achieve an adequate response with the lowest effective amount — some patients only take it once or twice daily
  • Not for children: Lomaira is not recommended for patients 16 years of age or younger

Is Lomaira a Controlled Substance?

Yes. Lomaira is classified as a Schedule IV controlled substance (CIV) under the DEA. This means:

  • It requires a valid prescription from a licensed provider with DEA prescribing authority
  • Refill rules vary by state — many states limit to 30-day supplies with no automatic refills for Schedule IV drugs
  • It has some potential for dependence and misuse — take only as prescribed
  • Store it securely — do not share it with others, even if they have the same condition

Lomaira vs. Other Phentermine Products

Phentermine is available under several brand names and as a generic. Here's how Lomaira compares:

  • Adipex-P (37.5 mg): Higher dose, taken once daily in the morning. More widely stocked. Longer duration of action.
  • Generic phentermine (15–37.5 mg): Widely available, very low cost, taken once daily.
  • Lomaira (8 mg): Lowest dose, shortest-acting, meal-timed dosing, brand-only. Preferred by patients who want more control over when appetite suppression occurs, or who experience side effects with higher doses.

How Much Does Lomaira Cost?

The average retail price for Lomaira is approximately $70 for 30 tablets. However, with savings programs, costs can be dramatically lower:

  • Lomaira Lo-Cost Access Program: Up to $0.50/tablet ($15 for 30, $45 for 90)
  • GoodRx: As low as $17 for 30 tablets at participating pharmacies
  • SingleCare: ~$26 for 30 tablets

Finding Lomaira at a Pharmacy

Because Lomaira is brand-only with no generic equivalent, it's not stocked at every pharmacy. If you're having trouble finding it, medfinder is a paid service that contacts pharmacies near you to locate which ones have it in stock. Results are texted to you.

Frequently Asked Questions

Lomaira (phentermine hydrochloride 8 mg) is FDA-approved as a short-term adjunct to a weight reduction program that includes exercise, behavioral modification, and a reduced-calorie diet. It is indicated for adults with a BMI of 30 or greater, or 27 or greater with at least one weight-related condition such as high blood pressure, type 2 diabetes, or high cholesterol.

The standard Lomaira dosage is one 8 mg tablet taken three times daily, 30 minutes before each meal. The tablet is scored and can be cut in half for a 4 mg dose. Your prescriber will individualize the dose — some patients only take Lomaira once or twice daily based on their needs and tolerability.

Both Lomaira and Adipex-P contain phentermine hydrochloride, but they are different formulations. Lomaira contains 8 mg and is taken up to three times daily (short-acting, meal-timed). Adipex-P contains 37.5 mg and is taken once daily in the morning (longer-acting). They have the same active ingredient but different dosing profiles and intensity.

Lomaira is a short-acting medication that begins suppressing appetite within a short time after taking it and works for approximately 4 hours per dose. Phentermine typically reaches a steady state in your system after about 4–5 days of regular use. Weight loss results depend on adherence to dietary changes and exercise alongside the medication.
