This is the interactions section of this product’s FDA label — what the manufacturer documented for this drug. It is not a check of your medication list, and a drug missing from it has not been cleared: licensed clinical databases list far more interactions than any single label does. Before combining medicines, ask a pharmacist, who can check everything you take at once and will do it for free.

Drug interactions
Table 5 presents clinically important drug interactions with Citalopram Capsules. CYP2C19 inhibitors and CYP2C19 poor metabolizers: Avoid concomitant use. There is an increased risk of QT prolongation with concomitant use.
Table 5: Clinically Important Drug Interactions with Citalopram Capsules Monoamine Oxidase Inhibitors (MAOIs) Clinical Impact: Concomitant use of SSRIs, including Citalopram Capsules, and MAOIs increases the risk of serotonin syndrome.
Intervention: Citalopram Capsules is contraindicated in patients taking MAOIs, including MAOIs such as linezolid or intravenous methylene blue.
Pimozide Clinical Impact: Concomitant use of citalopram with pimozide increases plasma concentrations of pimozide, a drug with a narrow therapeutic index, and may increase the risk of QT prolongation and/or ventricular arrhythmias compared to use of citalopram alone.
Intervention: Citalopram Capsules is contraindicated in patients taking pimozide. Drugs that Prolong the QTc Interval Clinical Impact: Concomitant use of citalopram with drugs that prolong QT can cause additional QT prolongation compared to the use of citalopram alone.
Intervention: Avoid concomitant use of Citalopram Capsules with drugs that prolong the QT interval (Citalopram Capsules is contraindicated in patients taking pimozide).
CYP2C19 Inhibitors Clinical Impact: Concomitant use of citalopram with CYP2C19 inhibitors increases the risk of QT prolongation and/or ventricular arrhythmias compared to the use of citalopram alone.
Intervention: Avoid concomitant use of Citalopram Capsules with CYP2C19 inhibitors. Other Serotonergic Drugs Clinical Impact: Concomitant use of Citalopram Capsules with other serotonergic drugs (including other SSRIs, SNRIs, triptans, tricyclic antidepressants, opioids, lithium, buspirone, amphetamines, tryptophan, and St. John's Wort) increases the risk of serotonin syndrome.
Intervention: Monitor patients for signs and symptoms of serotonin syndrome, particularly during Citalopram Capsules initiation and changes in citalopram dosage. If serotonin syndrome occurs, consider discontinuation of Citalopram Capsules and/or concomitant serotonergic drugs. Drugs That Interfere With Hemostasis (antiplatelet agents and anticoagulants) Clinical Impact: Concomitant use of citalopram and an antiplatelet or anticoagulant may potentiate the risk of bleeding.
Intervention: Inform patients of the increased risk of bleeding associated with the concomitant use of Citalopram Capsules and antiplatelet agents and anticoagulants. For patients taking warfarin, carefully monitor the international normalized ratio.
