How should I take citalopram?

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. Follow the directions on your prescription label.

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 longer before you 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.

What happens if I miss a dose?

Take the missed dose as soon as you remember. However, if it is almost time for the next regularly scheduled dose, skip the missed dose and take the next one as directed. Do not take extra medicine to make up the missed dose.

What happens if I overdose?

Seek emergency medical attention if you think you have taken too much of this medication. Symptoms of a citalopram overdose may include nausea, vomiting, tremor, sweating, rapid heartbeat, confusion, dizziness, seizures, and coma.

What should I avoid while taking citalopram?

Do not take citalopram together with escitalopram (Lexapro), isocarboxazid (Marplan), phenelzine (Nardil), rasagiline (Azilect), selegiline (Eldepryl, Emsam), or tranylcypromine (Parnate). Avoid drinking alcohol, which can increase some of the side effects of citalopram.

Avoid using other medicines that make you sleepy (such as cold medicine, pain medication, muscle relaxers, medicine for seizures, other medication for depression or anxiety). They can add to sleepiness caused by citalopram.

Citalopram can cause side effects that may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be awake and alert.

What are the possible side effects of citalopram?

Get emergency medical help if you have any of these signs of an allergic reaction: skin rash or hives; difficulty breathing; swelling of your face, lips, tongue, or throat.

Call your doctor at once if you have any new or worsening symptoms such as: mood or behavior changes, anxiety, panic attacks, trouble sleeping, or if you feel impulsive, irritable, agitated, hostile, aggressive, restless, hyperactive (mentally or physically), more depressed, or have thoughts about suicide or hurting yourself.
