When it comes to phentermine, there are no official clinical studies that can tell us exactly how long tolerance to the drug will last. However, patient reports suggest that it may persist for months or even years after you stop taking it. Phentermine is not considered to be an addictive substance, but it does produce tolerance over time. This is because the body is attempting to create a state of homeostasis, or balance.
Tolerance to phentermine can be both good and bad. For example, reducing thirst and insomnia may be beneficial, but suppressing appetite and energy levels is not. It's important to remember that it's not the phentermine that has stopped working; it's your body's natural intelligence that is at play here. Many people don't realize that tolerance to phentermine is a real possibility.
Your body learns your behavior patterns and defends itself accordingly. After multiple cycles of weight gain and loss, with or without the help of phentermine, it's likely that you will no longer be able to control your weight loss as easily as before. You'll need to make some changes to your lifestyle in order to see results. Tolerance to phentermine is especially common in patients who have been taking the drug for a long time or who are taking it for the second or third time.
In an effort to make phentermine work better, many patients turn to supplements.Phentermine is a popular and effective weight-loss medication, but unfortunately, many users report that it stops working after 2-3 months of use. If you're expecting phentermine to be a magic pill for weight loss, you should reconsider your approach or abandon the treatment altogether.
