Final answer:
Monoamine oxidase inhibitors (MAOIs) are non-psych medications that can cause serotonin syndrome by inhibiting the reuptake of serotonin and can lead to dangerous levels when combined with other serotonin-affecting drugs.
Step-by-step explanation:
A non-psych medication that can cause serotonin syndrome is a class of drugs known as monoamine oxidase inhibitors (MAOIs). These medications are typically used to treat depression and are known to inhibit reuptake of neurotransmitters including serotonin. While MAOIs can be effective for treating certain psychiatric conditions, co-administration with other substances that elevate serotonin levels, such as selective serotonin reuptake inhibitors (SSRIs), can lead to an excessive accumulation of serotonin in the synaptic cleft and potentially result in serotonin syndrome. Serotonin syndrome is a potentially life-threatening condition characterized by a range of symptoms such as agitation, confusion, rapid heart rate, dilated pupils, loss of muscle coordination or muscle rigidity, heavy sweating, diarrhea, headache, shivering, and goose bumps.
