Lithium - Coadministration of citalopram (40 mg/day for 10 days) as well as lithium (30 mmol/day for 5 days) had no significant result on the pharmacokinetics of citalopram or lithium.
Likewise, at the very least 14 days must be allowed after quiting citalopram before starting a MAOI (see WARNINGS and contraindications).
Pathologic modifications (degeneration/atrophy) were observed in the retinas of albino rats in the 2-year carcinogenicity study with citalopram.
