Citalopram and Other Antidepressants

Combining two anti-depressants is not recommended. You may believe that by combining two drugs of the same category would increase its effects. Wrong! First and foremost this will only lead to toxicity. Keep in mind that each drug classification has a specific site of action. This is the main reason why physician do laboratory tests, to determine which specific location is causing the abnormality. Citalopram affect brain chemicals namely serotonin, nor-epinephrine and dopamine. Administration of the same drug that alters these brain chemicals would only aggravate your symptoms. Remember the law of equilibrium, this is strongly implied in any use of pharmaceutical products.

Citalopram and Monoamine Oxidase Inhibitors

Selective serotonin re-uptake inhibitors and monoamine oxidase inhibitors can adversely interact with each other. This can result in psychosis, serotonin syndrome and hypersensitivity because of the increase in serotonin, nor-epinephrine and dopamine activity.

In certain cases where MAOIs are used as an alternative drug, there should be a 14 days gap before administration from the last intake of citalopram to MOIs. This is also is applicable if shifting is from a MAOI to SSRI.
