What Is Lomaira?

Lomaira is a prescription-only weight loss drug intended to help overweight or obese individuals lose weight.

Lomaira 8mg is the smallest dose of phentermine available on the market. It is a low-dose, butterfly-shaped tablet that patients can take up to three times per day.

Lomaira was approved by the FDA in 2016 for use within the United States. Its approval status varies in other countries, so please consult with a local healthcare provider or pharmacy for information in your region. ( 1 ). 

There is no generic equivalent at this time.

How It Works

Phentermine hydrochloride, the active ingredient in Lomaira, is a central nervous system stimulant.

It triggers a “fight or flight” type response ( 2 ). This medication decreases appetite and boosts energy, both of which promote faster weight loss for patients struggling to slim down.

Intended Use & Efficacy

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

Lomaira 8mg is designed for overweight or obese patients who have already tried losing weight with diet and exercise alone ( 1 ).

These tablets are an option for people with a body mass index (BMI) of:

  • Over 30 kg/m2 (classification: obese)
  • 27-30 kg/m2 (classification: overweight) + one or more weight-related condition

Several studies have supported the effectiveness of Lomaira in weight loss. A significant proportion of patients have reported considerable weight reduction when Lomaira was combined with a balanced diet and regular exercise. The detailed results and comparison studies can be found on the FDA’s website.

It’s important to note that Lomaira shouldn’t be used with certain medications or by individuals with specific health conditions, such as those with a history of heart disease, hyperthyroidism, glaucoma, or a history of drug misuse.

Always consult with your healthcare provider before starting a regimen with Lomaira.


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

Most notably, Lomaira is the only phentermine pill that can be taken up to three times per day.

Moreover, unlike other low-dose phentermine products that are only sold as capsules, Lomaira is a scored tablet. This preparation allows patients to further reduce their dose to 4mg if they do not require or tolerate the full eight milligrams. 

Lomaira is taken first thing in the morning, typically 30 minutes before breakfast. Additional doses of Lomaira may also be prescribed for 30 minutes before lunch and/or dinner ( 1 , 3 ).

The table below compares a typical Lomaira dosing schedule to that of higher-dose phentermine pills:

Like other weight loss medications, misuse of Lomaira may lead to dependency or addiction. Always take Lomaira exactly as prescribed and report any unusual behavior or cravings to your healthcare provider.

Benefits and Downsides

Smaller, split doses of Lomaira are beneficial for people who need more appetite suppression and energy later in the day but cannot tolerate higher-dose extended-release capsules.

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.

Lomaira may NOT be a good 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 the time or remembering to take the three pills
  • Want the most economical weight loss option

Once you stop taking Lomaira, you might experience weight gain or other withdrawal symptoms. It is important to have a post-medication plan, such as a maintenance diet and exercise routine, to sustain weight loss.

If Lomaira is not a suitable choice, other options include Qsymia and Contrave, which also aid in weight loss. However, the effectiveness, dosage, and side effects vary between these medications, so consultation with a healthcare provider is essential.

Side Effects of Lomaira

Lomaira is designed to suppress appetite and boost energy, but these weight loss pills can also cause a range of unwanted reactions.

The most common phentermine side effects are dry mouth, insomnia, and constipation ( 4 ):

Many patients’ side effects are effectively managed at home, but in rare cases, this medication may also cause serious heart and lung problems


Dozens of user-submitted Lomaira reviews further illustrate these points.

“Ok so my doctor prescribed me this pill which I have been taking for 3 months and it has done nothing for me. 🙁 I tried everything but nothing worked I only lost 9 pounds I know its better than nothing but Its a LOT less than I expected. Theres so many of you who have lost like 20+ in one month and heres me with 10 in 3. Very disappointing.”

“Love this! At first, I was frustrated at how slow I was losing weight. Only 12 pounds in a little over a month. But sometimes it’s more about the inches than the pounds. And us shorties know… 12 pounds can make a difference!! Still about 25 pounds to go… but I feel like it’s doable!! Keep going everyone!! We got this!!”

“First I was on phen 37.5, but the headaches and nausea were way way too much. My doctor swtched me to Lomaira after a couple of weeks and it’s going much better! I take 1 pill at breakfast and 1 at lunch and it keeps my hunger away til bedtime. I’ve lost almost 8 pounds this month and im happy with that. not losing as much as I did with the 37.5, but i can actually function so that’s worth it.”

How Much Does Lomaira Cost?

Lomaira is a prescription-only medication in most regions, including the United States. It is not available over the counter and should only be used under the guidance of a healthcare provider.

The price of Lomaira varies slightly from pharmacy to pharmacy, but it costs an average of $54 per month for a 90-tablet supply ( 7 ).

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 its 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.


Lomaira is produced and marketed by KVK Tech, Inc.

Founded in 2004, this pharmaceutical company is a self-proclaimed leader in developing, manufacturing, and marketing medications to meet unmet patient needs. Lomaira tablets, like all of their other products, are proudly made in America “in the strictest accordance with FDA, DEA, and DEP guidelines” ( 8 ).
