Can You Die From Taking Phentermine Overdose?
Yes, overdoes of Phentermine can result in death.
This medicine induces a hormonal response similar to “fight or flight” by stimulating the sympathetic nervous system. Small amounts of central nervous system activation can help you lose weight since it reduces hunger and increases energy. However, it is not always beneficial to activate the nervous system more than a limit.
The central nervous system can be overstimulated by phentermine, resulting in dangerously high blood pressure, heart rate, and even circulatory collapse. In addition, phentermine can increase the effects of other medicines if you take too much of them together.
Excess Phentermine consumption can also result in convulsions (seizures) and comas. In the event that too much of this drug is taken, these responses (convulsions) can lead to death from phentermine, especially in people who have other drugs in their systems.
