- Until you know how citalopram affects you, avoid driving, heavy machinery or hazardous activities if you feel drowsy or dizzy.
- Avoid or limit alcohol as it can increase chronic side effects.
- Older people are at higher risk of low sodium (hyponatraemia), falls and QT prolongation; clinicians may order ECGs and electrolyte checks.
- Prenatal and postnatal breastfeeding: weigh benefits and risks with your prescriber before starting or stopping therapy.
- Ask your pharmacist about over-the-counter cold, allergy and sleep products; some may interact.

- Other SSRIs: sertraline (Zoloft), escitalopram (Lexapro), fluoxetine (Prozac/Lovan), fluvoxamine (Luvox), paroxetine (Aropax). Escitalopram available as tablets is the S-enantiomer of citalopram and may be preferred for some patients.
- SNRIs: venlafaxine (Efexor XR), desvenlafaxine (Pristiq), duloxetine (Cymbalta) — often chosen when pain symptoms coexist with depression.
- Noradrenergic and other agents: mirtazapine (Avanza/Remeron) can help with sleep and appetite; vortioxetine (Trintellix) may help cognitive symptoms.
- Older options: tricyclic antidepressants such as amitriptyline or nortriptyline are used in selected cases but require surveillance of system activity for cardiac and anticholinergic effects.
