Lomaira 8mg is the smallest dose of phentermine available on the market. Phentermine (CIV) is a popular prescription-only weight loss medication and Lomaira is a low-dose, butterfly-shaped brand name tablet that patients can take up to three times per day.

Unlike other low-dose phentermine products, which are only sold as capsules, Lomaira is a scored tablet. This preparation facilitates further dose reduction to 4mg for patients who do not require or tolerate the full eight milligrams. 

Lomaira was approved by the FDA in 2016 ( 1 ). There is no generic equivalent at this time.

Lomaira is a central nervous system stimulant.

The active ingredient, phentermine hydrochloride (HCL) is thought to work by encouraging the release of certain chemicals in the brain, which create a systemic ‘fight or flight’-type response ( 2 ). As part of this response appetite decreases and energy use increases – both of which promote faster weight loss for patients struggling to slim down.

Intended Use

Lomaira (8mg phentermine) is designed to help obese patients lose weight

Lomaira, and other prescription appetite suppressants, are designed for overweight or obese patients who have already tried losing weight with diet and exercise alone. It is not intended as a long-term treatment for obesity, nor is it appropriate for healthy weight individuals simply looking to lose a few pounds.

Phentermine weight loss pills, including Lomaira 8mg, are an option for people with a body mass index (BMI) of 30+ kg/m2 or those with a BMI of 27-30 kg/m2 plus one or more weight-related condition such as type 2 diabetes, high cholesterol or high blood pressure ( 1 ).

However, this medication is not right for everyone – even if they fall within the above BMI ranges. A doctor must also consider the patient’s overall health status, medical history, other medications & supplements, and eventual weight loss goals before prescribing Lomaira.


The FDA approval of Lomaira 8mg opens-up several new phentermine dosing options for doctors and patients. 

It is the only phentermine pill that can be taken up to three times per day. Plus, Lomaira tablets are scored down the middle to facilitate easy at-home splitting, which allows patients that do not want or tolerate the entire 8 mg tablet to safely take just 4mg phentermine at a time.

Like other preparations of phentermine, Lomaira is taken first thing in the morning – typically 30 minutes before breakfast. However, unlike other phentermine pills, additional doses of Lomaira can be taken 30 minutes before each meal to provide extra boosts of the medication ( 1 ).

Here is a summary of when Lomaira can be taken, in comparison to other popular phentermine doses:

Lomaira (8mg) 15 - 18.75mg 30 - 37.5mg

The smaller, split doses are beneficial for people who need additional appetite suppression and energy later in the day, but cannot tolerate higher-dose extended release capsules or need help suppressing late-night cravings.

So, Lomaira may be a good option for patients who:

  • Struggle with afternoon or evening cravings
  • Experience strong side effects with higher doses of phentermine
  • Need a lower dose of phentermine due to other health issues
  • Prefer to take smaller doses of the stimulant throughout the day instead of one large dose in the morning

This low-dose pill can also be used as a way to gradually decrease dosage as patients come to the end of their prescription, especially if there is concern about phentermine withdrawal symptoms.

On the flip side, these small, divided doses may not be the best option for patients who:

  • Need a high-dose pill (i.e. 30mg or 37.5mg) to reap the medication’s effects
  • Struggle with stimulant-related insomnia
  • Have difficulty finding time or remembering to take the three pills
  • Want the most economic weight loss option

Lomaira Side Effects

Unfortunately, in addition to the desired effects of this weight loss medication, the chemical cascade triggered by phentermine also produces a slew of negative side effects.

The most common side effects of phentermine are ( 3 ):

  • Dry mouth
  • Insomnia
  • Constipation
  • Headache
  • Mood changes (“phen rage”)

For most patients, the above reactions prove relatively minor and are managed effectively at home. However, phentermine use is also linked to an increased risk of potentially life-threatening heart and lung problems. 

Contact your doctor or go to a hospital right away if you have any of the following symptoms while taking Lomaira:

  • Lightheadedness or fainting
  • Unusual swelling of feet or ankles
  • Trouble breathing, even with mild exertion
  • Extreme weakness or inability to carry-out daily activities
  • Chest pain

Where to Buy Lomaira

Lomaira is only available under a doctor's prescription

Lomaira is a prescription-only medication and class IV controlled substance in the US and abroad ( 4 ). Therefore, the only way to buy this medication legally is to:

  1. Schedule an appointment with your doctor to speak about weight loss.
  2. Obtain a valid prescription for Lomaira, if the doctor thinks phentermine is right for you.
  3. Fill the script any major pharmacy.

Buying phentermine online or without a prescription is illegal and potentially dangerous.

Lomaira Cost

The price of Lomaira varies slightly from pharmacy to pharmacy, but it costs an average of $54 per month for a 90-tablet supply ( 5 ). 

This relatively-high monthly cost is one reason that some patients prefer to take a generic tablet and split it, or use generic phentermine 15mg capsules.

Thankfully, in response to this concern, KVK Tech launched their Lo-Cost Access Program. Using the free savings card, patients that pay for their prescription out-of-pocket are only charged 50¢ per tablet, or no more than $45 per month.

There is no Lomaira generic equivalent at this time. The 8 mg dose of phentermine is only available as this brand-name pill.

Lomaira Reviews

Lomaira provides an exciting, new dosage option for doctors and patients, but does it really work? Most users love the low-dose pill’s versatility and lack of side effects, but some people complain of severe constipation. 

Lomaira has an average user rating of 4.6/5 stars:

I started with Phentermine 37.5 but it made me jittery, so cut it in half and still too much. Now I am taking 4 mg (cutting Lomaira 8 mg in half) in the morning and 1/2 hour before lunch. It is stopping my appetite and I've lost 18 lbs in 3 months.
