Patients receiving this combination should be monitored for the emergence of serotonin syndrome or other adverse effects. There is also a risk of additive CNS depression (drowsiness) when buspirone is given concomitantly with barbiturates. However, its CNS effects in any individual patient may not be predictable. Buspirone does not inhibit monoamine oxidase. Methylene blue is a thiazine dye that is also a potent, reversible inhibitor of the enzyme responsible for the catabolism of serotonin in the brain (MAO-A) and buspirone increases central serotonin effects.
