What is Acxion?

phentermine hydrochloride (chemical structure)

The active ingredient is a stimulant called phentermine hydrochloride, often abbreviated as phentermine HCL.

Phentermine is prescribed for short-term weight management in overweight and obese patients. Doctors currently use body mass index (BMI) to determine if a patient is overweight or obese.

To qualify for Acxion weight loss pills, a patient must have a:

  • BMI ≥ 30 kg/m2, or
  • BMI ≥ 27 kg/m2 plus one or more weight-related condition

Weight-related conditions that might make an overweight patient eligible for phentermine include type 2 diabetes, controlled hypertension (high blood pressure), or hyperlipidemia (high cholesterol), or sleep apnea (1).

Doctors also assess a patient’s medical history, pre-existing conditions and recent medications to determine whether phentermine is an appropriate and safe option. This medication has a long list of contraindications, so it’s important that you are honest with your prescribing doctor at the initial appointment.

Acxion is approved for 12 weeks continuous use or 36 weeks of intermittent use: 4 weeks on, 4 weeks off (1).

Regardless of how you take Acxion, it is important to use these weight loss pills in combination with healthy diet and increased [doctor-approved] physical activity.

When and How to Take Acxion

Always take this medication exactly as prescribed.

Unless otherwise directed by your doctor or pharmacist, take Acxion first thing in the morning. This medication is most effective when taken and digested on an empty stomach, so take it at least 30-50 minutes before breakfast with a full glass of water (2).

The maximum dose of Acxion is 30 mg per day. The 15mg dose can be taken two times per day, while the 30mg dose is only taken once per day.

If you are unsure how to take your specific dose of Acxion (phentermine), speak with your pharmacist. He or she can help determine the best schedule for you, taking into account other medications and your individual work-sleep schedule.


Acxion tablets

Acxion is currently available in two doses: 15mg and 30mg. This medication is available in three different forms:

  • Acxion (tablet)
  • Acxion C (capsule)
  • Acxion AP (extended-release tablet)

Acxion 15mg

Acxion 15mg comes as a tablet and capsule.

Prescribing guidelines for phentermine dictate that doctors should start patients on the lowest-possible dose and then only increase dosage if needed. This practice is to minimize the risk of unpleasant and unnecessary side effects.

So, doctors commonly start their patients on Acxion 15mg once per day. Then, if 15mg isn’t producing the desired weight loss after 1-3 months,  increase daily dosage to 30mg.

Acxion 30mg

Acxion 30mg is sold as a tablet, capsule and extended-release tablet, and remains the most-prescribed dose of this medication (1).

Patients can take 30mg of Acxion either as a single tablet before breakfast, or as a split dose. The split dose consists of two 15mg pills taken at different times: typically one in the early morning and the other sometime midday. This can be a good option for patients that struggle with nighttime cravings or binges.

Axcion AP (the extended-release tablet) is ideal for patients that only want to take one pill in the morning, but could benefit from the pill’s appetite suppression and energy boosting effects all day long.

Acxion Compared to Other Weight Loss Pills

Acxion is well-known and commonly requested, but it is not the only option for weight loss. Terfamex, another brand of phentermine, and Redotex, a weight loss supplement, are also popular in Mexico.

Acxion or Terfamex

Terfamex 15 mg box

Both are brand name preparations of phentermine weight loss pills.

The active ingredient is the same, however the forms and dosage are different. Acxion is available in tablet (normal and extended-release) and capsule form, while Terfamex is sold as capsules and orally disintegrating tablets (ODT). More, Acxion is only produced in doses of 15mg and 30mg. Terfamex is offered in 15mg, 30mg and 37.5mg doses.

Acxion or Redotex

box of Redotex NF

Acxion and Redotex are both prescription-only weight loss medications sold in Mexico. Acxion contains phentermine HCL as its active ingredient, while Redotex contains a combination of stimulants: norpseudoephedrine, atropine sulfate, diazepam, aloin, and triiodothyronine.

However, safety concerns about Redotex remain widespread. In fact, Redotex is illegal in the United States due to significant safety concerns. Talk to your doctor about the benefits and risks of these medications before filling your prescription ( 9 ).

Acxion or Phen Caps

Phen Caps bottle and capsules

Phen Caps is a popular weight loss supplement that does not contain any phentermine. Instead, Phen Caps contains nine natural ingredients to suppress appetite, boost energy and promote weight loss – without the unwanted side effects. These capsules are 100% made in the USA and consistently receive positive customer reviews. They are an effective and safe option to help you reach your weight loss goals naturally.
