Laboratory tests may include blood and urine analyses to detect elevated levels of the medication or metabolic imbalances. Healthcare providers also evaluate for potential interactions with other substances known to cause adverse effects when combined with MAOIs. Continuous monitoring is critical in managing suspected poisoning cases or adverse reactions.
Treatment Protocols: Treatment approaches focus on stabilizing the patient and reducing the toxicity effects. These may include:
