Citalopram does not typically interact with most antihypertensive agents, but certain drugs that affect the CYP2C19 or CYP3A4 pathways might alter its levels. Inform your prescriber about all cardiovascular medicines you are using so they can assess any potential interaction.
Palpitations could signal QT interval prolongation or another cardiac effect. Seek immediate medical attention, especially if accompanied by dizziness, fainting, or chest discomfort, and have an ECG performed to evaluate your heart rhythm.
Yes, but keep the medication in its original packaging with a copy of the prescription. Carry it in your hand luggage to avoid temperature extremes and ensure compliance with the destination country’s regulations on prescription drugs.
Most patients notice a modest improvement after 2-4 weeks, though full therapeutic effects may require up to 8 weeks of consistent dosing. Patience and regular follow-up with your clinician are essential.
A direct switch is often possible, but a brief cross-taper may be recommended to minimise discontinuation symptoms. Your prescriber will design a transition plan based on the specific SSRI you are using.
SSRI-induced alterations in serotonin can affect REM sleep, leading to more vivid or intense dreams. This side effect is usually temporary and diminishes as the body adapts to the medication.
Some herbal products, such as St John’s wort, also increase serotonin and can raise the risk of serotonin syndrome. Always discuss any supplements with your healthcare provider before adding them to your regimen.
Keep the tablets in a cool, dry place away from direct sunlight. If ambient temperatures exceed 30 °C, store the medication in a climate-controlled area, such as a refrigerator, but allow it to reach room temperature before ingestion.
Weight gain or loss may occur with long-term SSRI use, though the effect varies between individuals. Monitor your weight periodically and discuss any concerning changes with your clinician.
Routine blood monitoring is not required for most patients. However, if you have liver or kidney disease, are on interacting medications, or develop side effects, periodic laboratory tests may be advised.
Citalopram hydrobromide is an antidepressant belonging to the selective serotonin reuptake inhibitor (SSRI) class. It is marketed in the United Kingdom as a prescription-only medicine (POM) and is available in pill form in strengths of 10 mg and 20 mg. The medication is used to treat a range of mood-related conditions and is regulated by the Medicines and Healthcare products Regulatory Agency (MHRA).
Citalopram blocks the reuptake of the neurotransmitter serotonin (5-hydroxytryptamine) into presynaptic neurons. By increasing serotonin levels in the synaptic cleft, it enhances serotonergic neurotransmission, which is thought to improve mood, anxiety, and related symptoms. The drug reaches peak plasma concentrations about 2-4 hours after oral administration, has a half-life of roughly 35 hours, and is metabolised primarily by the liver enzyme CYP2C19, with contributions from CYP3A4 and CYP2D6.
Citalopram is generally prescribed for adults, including older adults when lower doses are used.
Off-label use requires medical supervision and an individualized risk assessment.
Absolute contraindications
Relative contraindications
Special populations such as patients over 65 years are usually started at 10 mg and should not exceed 20 mg due to the increased risk of QT prolongation.
These effects are usually transient and lessen within the first few weeks of therapy.
