What should you know about citalopram fatigue?

Feeling sleepy, slowed down, or short of energy may be a side effect of citalopram. It can be more noticeable soon after treatment begins or after the dose changes. Depression itself can also disturb sleep and reduce energy, so the medicine is not always the only explanation.

Other possibilities include poor sleep, dehydration, anaemia, infection, alcohol use, or another medicine taken at the same time. Fatigue can also occur with conditions such as Burnout, Chronic Fatigue Syndrome, Chronic Kidney Disease, Coeliac Disease, or COVID-19. The pattern, timing, and other symptoms help a clinician sort these possibilities.

Take citalopram exactly as prescribed and do not stop it suddenly. Keep a brief record of when tiredness appears, your sleep quality, and any recent dose or medicine changes. Until you know how it affects you, avoid driving, cycling, or using machinery if you feel drowsy or your concentration is reduced.

Regular meals, enough fluids, and a steady sleep routine may help. Do not use alcohol to counter tiredness, because it can worsen sleepiness and affect mood. Arrange a GP or prescriber review if fatigue interferes with work, study, daily care, or emotional recovery.

Seek urgent medical help if tiredness comes with fainting, severe confusion, difficulty breathing, chest pain, a seizure, or thoughts of harming yourself. Contact a clinician promptly if you cannot stay awake, symptoms are rapidly worsening, or you have marked agitation, fever, sweating, shaking, diarrhoea, or muscle stiffness after a medicine change.

Ask whether the timing fits a citalopram effect, whether another medicine or health problem could contribute, and whether a dose-time change or alternative treatment should be considered. Bring your medicine list and fatigue notes.
