How Long Do The Side Effects Caused Due To Phentermine Last?

Hi, I think my sister has overdosed on phentermine. She is having hallucinations and horrible thoughts. It has really scared her. She has stopped taking them completely now, the last pill she took was about 7 days ago. Will these side effects wear off? Is there anything she should be doing?

Hi,

Phentermine is a prescription medication used for weight loss that can cause several side effects, including hallucinations, psychosis, and depression. If your sister has experienced these symptoms, she must seek medical attention immediately.

The duration of the side effects caused by phentermine can vary depending on several factors, including the dosage taken, the individual's overall health, and the duration of use. In some cases, side effects may persist for several weeks or months after discontinuing the medication.

It's important to note that stopping phentermine abruptly can also cause withdrawal symptoms, such as fatigue, depression, and irritability. If your sister has stopped taking phentermine, she should speak to her doctor about the best way to taper off the medication to avoid withdrawal symptoms.

In conclusion, if your sister is experiencing hallucinations and other disturbing thoughts after taking phentermine, she must seek medical attention immediately. The duration of the side effects can vary, and her doctor can provide personalized recommendations for managing her symptoms and ensuring her safety.

Take care. Hope I have answered your question. Let me know if I can assist you further.

Regards,
Dr. Priyanka, General & Family Physician
