When a person takes too much phentermine, overdose symptoms may initially include shakiness, nausea and vomiting, rapid breathing, and diarrhea. After the initial stimulatory reaction, people often develop extreme fatigue. Various treatment options are available for a phentermine overdose, including certain medications, "pumping the stomach," and supportive care. Be sure to seek medical attention immediately if you think you may have overdosed on phentermine.
Phentermine is a weight-loss medication that is available by prescription only. Phentermine overdose effects can be very dangerous and will vary depending on a number of factors, including the phentermine dosage and whether it is taken with any other medicines, food, alcoholic beverages, or street drugs.
If you happen to overdose on phentermine, seek medical attention immediately.
Initially, a phentermine overdose typically causes symptoms (due to its action as a stimulant) such as:
- Shakiness (tremor)
- Rapid breathing
- Violent behavior
- An irregular heart rhythm (arrhythmia)
- High blood pressure (hypertension) or low blood pressure (hypotension)
- Nausea and vomiting
- Diarrhea and cramps
- Loss of life.
After the initial stimulatory reaction, people often develop extreme fatigue.
The treatment for a phentermine overdose will vary. If the overdose was recent, a healthcare provider may give certain medicines or place a tube into the stomach to "pump the stomach." Treatment also involves supportive care, which consists of treating the symptoms that occur as a result of the overdose. For instance, medications may be necessary to decrease the heart rate and blood pressure.
It is important that you seek medical attention immediately if you believe that you may have overdosed on phentermine.
