How Adipex Is Processed in the Body

When you take Adipex, your body absorbs it through your stomach. Then it moves into your bloodstream. From there, it travels to your brain and other parts of your body. Your liver works to break down the medicine. After that, your kidneys help remove it from your body.

This process takes time. Most of the drug leaves your system in a few days. But small amounts can stay longer. That’s why people wonder how long does Adipex stay in your system and how it affects drug test results.

The time phentermine lasts can depend on your size, age, and how your body works. Some people who take 15mg may notice lighter effects. Others on 37.5mg may feel stronger results. But once the effects wear off, small amounts of the drug can still stay in your system.

How Long Does 15mg Phentermine Stay in Your System?

A lower dose like 15mg usually leaves your system faster than higher doses. However, it still depends on your body. For many people, 15mg of phentermine can be found in urine for 1 to 3 days after use.

The half-life of phentermine is about 20 hours. This means it takes around 20 hours for half the drug to leave your body. So, even a 15mg dose may stay in your system for several days before it is completely gone.

Does Adipex Show Up on a Drug Test?

If you are asked to take a test, tell them you are using Adipex. Bring your prescription with you. This can help avoid problems and confusion. If needed, the sample can be tested further to show that it is from Adipex and not an illegal drug.

How to Get Phentermine Out of Your System Faster
