Qsymia Overdose

If you believe you have overdosed on Qsymia (phentermine and topiramate), seek immediate medical treatment. Some of the potential problems that may occur if too much of this drug is taken include seizures, hallucinations, and an abnormal heartbeat, just to name a few. A healthcare provider may treat these symptoms by "pumping the stomach," administering activated charcoal, or providing supportive care.
