Phentermine is a stimulant drug that is commonly used for short-term weight loss. The duration of phentermine in the system can vary depending on several factors including the individual's metabolism, the frequency and dose of the medication, and any underlying health conditions.
According to the most recent data, the average half-life of phentermine is approximately 20 hours. This means that half of the medication is eliminated from the body within this timeframe. However, it's important to note that the drug can be detected in the body for longer periods, particularly if high doses or extended use are involved.
In general, the effects of phentermine are felt within three to four hours after ingestion and last for about one to two days. After stopping the medication, the appetite suppressant effects gradually diminish, and the person may start to gain weight if calorie intake is not restricted.
It's crucial for individuals taking phentermine to consult with their healthcare provider before starting the medication and to adhere to the prescribed dosage and dosage schedule. With careful use, phentermine can be an effective tool in managing weight loss when used short-term alongside a balanced diet and regular physical activity plan. However, the potential for addiction and abuse exists with phentermine, making it a controlled substance and only intended for use under the supervision of a healthcare professional.
