  • Phentirimine is an over the counter diet supplement

  • It is clearly marketed as an alternative to Phentermine

  • It supposedly works as an appetite suppressant

  • Meant to be combined with a complete diet plan to lower weight
  • The name of this non-prescription diet pill is not only similar to the name of the prescription drug, but its white and blue colored capsules have clearly been designed to mimic its appearance, as well.

    No Ingredients Listed

    The ingredients in the Phentirimine formula are unknown. When this review was written, there was absolutely no information about this diet pill’s ingredients on its marketing page or anywhere else. This automatically raises some obvious concerns about this product. Without a list of ingredients, it instantly makes one wonder what the manufacturer has to hide. Furthermore, it means that is impossible to believe any claims that are made about this product being beneficial for weight loss.

    What is Known About the Phentirimine Formula

    All that is known about this diet pill formula is that it contains no amphetamines, it is an appetite suppressant, it is GMP certified, and you don’t need a prescription to buy it. In other words, virtually nothing is known about it. There isn’t even any mention of side effects. In fact, users are simply directed to contact their doctor if they notice adverse effects.

    That being said, according to the directions for this dietary supplement, users are instructed to take 1 capsule before breakfast or prior to morning exercise and 1 again in mid-afternoon, but should not take a pill in the evening. Thus, although it isn’t officially stated, based on the instruction not to take the pills in the evening, it is likely that Phentirimine contains at least one stimulant powerful enough to risk side effects that could disrupt sleep or cause insomnia.

    For instance, there is a good chance that it may contain caffeine as studies have linked this stimulant to sleep disturbances.

    Users are warned not to exceed more than four capsules per day, and it is suggested to those who weigh less than 150 pounds to take half the recommended dose for the first week. At the time this review was written, a 30 day supply (60 capsules) cost $79.99.

    Due to the severe lack of information about this product there is no way to know if Phentirimine is safe or effective for weight loss. In short, this diet pill cannot be trusted. Therefore, purchasing this product is not recommended. However, if it is something that interests you, talk to your doctor about it first and find out the information you need to know.

    Update February 2020 – Phentirimine is Unavailable

    Not surprisingly, as of February 2020, Phentirimine can not be found for sale online. The product sales page no longer exists and these diet pills are not sold on Amazon or at any other online retailer, reputable or otherwise.  That said, it is for the best that this dietary supplement, which was marketed as a Phentermine alternative, is no longer available for sale. This is especially true since it lacked credibility even when it was around.

    Take Care to Scrutinize the Diet Pills that Interest You

    Phentirimine is only one of many OTC diet pills that lack integrity. Today, just as was the case years before, you can’t be too careful when it comes to selecting an over the counter diet pill that you would like to try. For this reason, it is important that you keep the following in mind when you make your selection:

    Read the Ingredients

    Make sure the diet pill you are considering has an ingredients list. If you cannot easily find out what is in the formula of the product, it’s not worth your time, money or risking your health over. A reputable manufacturer will be transparent about the formula of its diet pill. Knowing the ingredients is important not only to research their potential benefits, but to make sure that you do not have any allergies to the substances or that they will not negatively interact with other medications or supplements you may be taking.

    Investigate the Claims

    It’s not good enough for a manufacturer simply to claim that its product is a non-prescription alternative to Phentermine, or to imply this through the product name, as was the case with Phentirimine. For starters, you should not trust any manufacturer who claims that their product is a Phentermine or Adipex OTC alternative, because these supplements do not legally exist.  Secondly, don’t just take a manufacturer at its word that its diet pill will deliver certain benefits. Have a look at the ingredients list and check to see what scientific studies have found in regard to the potential advantages they might offer individuals seeking to lose weight.

    Research the Company that Manufactures the Product

    Finally, have a look at the company who stands behind the product. Do they have an official webpage? Have there been complaints about them? What other products do they make? What do customers have to say?

    Do your best to protect yourself when searing for the best OTC diet pills. Don’t ever settle for a third-rate and potentially unsafe weight loss aids like Phentirimine. You have plenty of better options.
