Selective serotonin reuptake inhibitor (SSRI)
Switching to or from Citalopram
Switching medications is more nuanced than simply stopping one and starting another. For Citalopram (Citalopram), the right protocol depends on whether the switch is within the same class, across classes, the half-life of the medications involved, and any underlying disease control. This page outlines the practical considerations at 10mg, 20mg, 40mg.
Switching within the same class
Switching from another Selective serotonin reuptake inhibitor (SSRI) agent to Citalopram, or vice versa, is usually direct: the prescriber establishes the equivalent dose of Citalopram and the schedule, and the change happens on a defined day. Symptom monitoring during the first weeks confirms the new regimen is delivering equivalent control. Citalopram selectively inhibits the serotonin reuptake transporter, increasing synaptic serotonin availability with limited affinity for noradrenaline transporters or other receptors.
Switching across classes
Switching to Citalopram from a different therapeutic class is more involved. Some switches require a washout period (especially when crossing receptor antagonists/agonists or shared metabolic pathways), others use cross-titration where both medications overlap briefly. The prescriber chooses the protocol based on the medications involved, the indication and individual factors at 10mg, 20mg, 40mg.
Frequently asked questions
Can I switch directly from another medication to Citalopram? ▾
Sometimes yes — within the same class, direct switches are common. Across classes, a structured protocol (washout or cross-titration) is usually safer. The prescriber confirms whether direct switch to Citalopram at 10mg, 20mg, 40mg is appropriate.
What should I do if the switch isn't working? ▾
Switching results vary; the underlying condition may need a few weeks to restabilise on the new medication. If symptoms worsen significantly or new side effects appear, contact the prescriber for review rather than waiting indefinitely or self-switching back to the original medication.
