Phentermine is a medicine that helps people lose weight. It’s used for a short time to help people who are overweight or obese. It works by making you feel less hungry.
Doctors often prescribe it along with diet and exercise to help people lose weight, especially if they have health problems like high blood pressure or diabetes.
Phentermine’s duration in the system is influenced by several factors:
Dosage: Higher doses of phentermine take longer to metabolize and eliminate from the body.
Frequency of Use: Regular use can lead to accumulation of the drug in the system, extending the elimination time.
Metabolism: Individuals with faster metabolisms process and eliminate phentermine more quickly than those with slower metabolisms.
Age: Older individuals generally have slower metabolisms, which can prolong the presence of phentermine in their systems.
Body Mass: Higher body fat percentages can store phentermine metabolites longer, releasing them slowly into the bloodstream.
Hydration Level: Proper hydration helps eliminate phentermine metabolites more rapidly through urine.
Kidney and Liver Function: Impaired kidney or liver function can slow down the metabolism and excretion of phentermine, leading to a longer stay in the system.
These factors collectively determine how long phentermine remains in an individual’s system.
Phentermine can be detected in the body through various types of drug tests for different timeframes:
Urine tests: Phentermine can be detected in urine for 24 to 72 hours after last use, with most studies suggesting a detection window of around 48 hours.
Blood tests: Phentermine is typically detectable in blood for 6 to 12 hours after last use, although some studies suggest it may remain present for up to 24 hours.
Saliva tests: Phentermine can be detected in saliva for 2 to 4 days after last use, with most research indicating a detection window of around 3 days.
Hair tests: Phentermine can be detected in hair samples for up to 90 days after last use, although this is highly dependent on the length and growth rate of the individual’s hair.
Scientific research suggests that phentermine typically remains in an individual’s system for a relatively short period. A study published in the Journal of Analytical Toxicology found that phentermine was detectable in urine for up to 48 hours after last use, while another study published in the European Journal of Clinical Pharmacology reported detection times ranging from 6 to 24 hours in blood samples.
