Citalopram is an antidepressant in a group of drugs called selective serotonin reuptake inhibitors (SSRIs). Citalopram affects chemicals in the brain that may become unbalanced and cause depression.
Citalopram is used to treat depression.
Citalopram may also be used for purposes other than those listed in this medication guide.
Take this medication exactly as it was prescribed for you. Do not take the medication in larger amounts, or take it for longer than recommended by your doctor. Your doctor may occasionally change your dose to make sure you get the best results from the medication.
Try to take the medicine at the same time each day.
To be sure you get the correct dose of liquid citalopram, measure the liquid with a marked measuring spoon or medicine cup, not with a regular table spoon. If you do not have a dose-measuring device, ask your pharmacist for one.
It may take 4 weeks or more for you to start feeling better. Do not stop using citalopram without first talking to your doctor. You may have unpleasant side effects if you stop taking this medication suddenly.
Store citalopram at room temperature away from moisture and heat.

Celexa (citalopram HBr) is an orally administered selective serotonin reuptake inhibitor (SSRI) with a chemical structure unrelated to that of other SSRIs or of tricyclic, tetracyclic, or other available antidepressant agents. Citalopram HBr is a racemic bicyclic phthalane derivative designated (±)-1-(3-dimethylaminopropyl)-1- (4-fluorophenyl)-1,3 dihydroisobenzofuran-5-carbonitrile, HBr. Citalopram HBr occurs as a fine, white to off-white powder. Citalopram HBr is sparingly soluble in water and soluble in ethanol. Celexa (citalopram hydrobromide) is available as tablets or as an oral solution. Celexa 10 mg tablets are film-coated, oval tablets containing citalopram HBr in strengths equivalent to 10 mg citalopram base. Celexa 20 mg and 40 mg tablets are film-coated, oval, scored tablets containing citalopram HBr in strengths equivalent to 20 mg or 40 mg citalopram base. The tablets also contain the following inactive ingredients: copolyvidone, corn starch, crosscarmellose sodium, glycerin, lactose monohydrate, magnesium stearate, hypromellose, microcrystalline cellulose, polyethylene glycol, and titanium dioxide.
