3 Reasons why phentermine cause a positive drug test result

Phentermine is a medication prescribed to aid weight loss, and it belongs to the class of amphetamines. Due to its chemical composition, it may cause a positive result on a drug test for amphetamines. Amphetamines are a class of drugs that stimulate the central nervous system, which includes the brain and spinal cord. These drugs are often prescribed to treat conditions like attention deficit hyperactivity disorder (ADHD), narcolepsy (a sleep disorder), and obesity. Amphetamines work by increasing the levels of certain neurotransmitters, such as dopamine and norepinephrine, in the brain. This leads to an increase in alertness, attention, and energy. And due to this very reason, these drugs are abused due to the stimulating effects they cause.

why will phentermine cause a positive drug test

Phentermine , due to its chemical structure, metabolism, dosage, and the testing method used, may cause positive drug test result. Here’s why:

  • 1. The chemical structure of phentermine is similar to amphetamines, which can lead to a false positive result for amphetamines on a drug test. Now, amphetamines are commonly abused for their stimulating effects, which can lead to addiction, tolerance, and other negative health effects. And when anyone takes phentermine, their body metabolizes it into amphetamine and methamphetamine byproducts, which can also result in a positive drug test.
  • 2. The dosage of phentermine someone takes determines the likelihood of a positive drug test result. If anyone consumes higher doses or has been using phentermine for an extended period it will increase the levels of amphetamine and methamphetamine byproducts in their system, making it more likely to show up on a drug test.
  • 3.The third thing to keep in mind is, the type of drug test used, can also impact the likelihood of a positive result. Some tests are more sensitive than others and may detect lower levels of amphetamines or their byproducts, which can increase the likelihood of a positive result.

It is important to remember that having a valid prescription for phentermine and informing the tester can help account for a false positive result. However, taking phentermine without a prescription is illegal and can lead to legal consequences.

However, if you are taking phentermine as prescribed by a licensed healthcare provider and have a valid prescription, you should inform the individual administering the drug test about your medication before taking the test. This way, they can take into consideration that you are taking a prescription medication that may produce a positive result on the test.

On the other hand, taking phentermine without a prescription or not as prescribed is illegal and may pose a significant risk to your health. Additionally, if you are subjected to a drug test and have phentermine in your system without a valid prescription, you may face legal consequences or disciplinary action.

To sum up, phentermine can cause a positive result on a drug test for amphetamines, but if you have a valid prescription and inform the tester, it should not be a problem. However, taking phentermine without a prescription is illegal and can have serious consequences.
