Final answer:
Serotonin syndrome results from overstimulation of serotonin receptors due to the combined use of certain medications. It is a serious condition that may require stopping the causative medication and can be life-threatening.
Step-by-step explanation:
The condition that results from an overstimulation of central and peripheral serotonin receptors and can occur when certain medications are taken in combination is Serotonin syndrome. This syndrome is a potentially life-threatening state that can happen following the use of serotonergic drugs or, more commonly, the concurrent use of multiple such drugs.
The symptoms range from mild (shivering and diarrhea) to severe (muscle rigidity, fever, and seizures). If left untreated, severe serotonin syndrome can cause death. Treatment may include discontinuing medications that contribute to the syndrome and, in some cases, the use of serotonin antagonists like cyproheptadine.
