The active ingredient in Celexa, citalopram hydrobromide, belongs to a group of antidepressants called SSRis. SSRIs are the most commonly prescribed antidepressant drugs.
SSRIs like citalopram hydrobromide work by blocking the reuptake (reabsorption) of the neurotransmitter serotonin, making it more available for use by the brain. Increased availability of serotonin is associated with conditions like elevated mood, which are effective in relieving symptoms of mood disorders like depression.
Celexa is mainly prescribed to treat subtypes of depression and major depressive disorder. Celexa may also be used to treat obsessive compulsive disorder (OCD), panic disorder, dysthymia, anxiety, body dysmorphic disorder and premenstrual dysphoric disorder.
Celexa is available as 10 mg, 20 mg or 40 mg oral tablets.
Celexa tablets may contain the following inactive ingredients: corn starch, glycerin, croscarmellose sodium, magnesium stearate, lactose monohydrate, copovidone, microcrystalline cellulose, hypromellose, titanium dioxide, polyethylene glycol and iron oxide coloring agents.
Dosage of Celexa will vary depending on physician recommendation, age, severity of the condition and response to the treatment.
Celexa is usually administered in a single dose taken in the morning or the afternoon. The maximum daily dosage for Celexa is 40 mg.
Celexa can be taken either with or without food. Food does not affect how the drug is absorbed by the body.
However, taking Celexa with a meal may help prevent nausea.
Celexa should be taken exactly as prescribed for the drug to be effective. Do not take Celexa more or less than prescribed to avoid unwanted conditions such as worsened side effects.
Do not abruptly stop taking Celexa as it may cause withdrawal symptoms. Celexa doses should be gradually decreased should a patient wish to stop taking the medication.
Benefits of Celexa may not be immediate. It may take up to a month for the effectiveness of the drug to be noticeable.
