Families and caregivers must closely watch patients who take Celexa. It is important to keep in close contact with the patient's doctor. Tell the doctor right away if the patient has symptoms like worsened depression, suicidal thoughts, or changes in behavior. Discuss any questions with the patient's doctor.

Celexa is not approved for use in children. Talk with the doctor.

  • you have a certain type of irregular heartbeat (long QT syndrome), slow heartbeat, severe heart failure, a recent heart attack, or uncorrected low blood potassium or magnesium levels
  • you are taking or have taken linezolid, a monoamine oxidase inhibitor (MAOI) (eg, phenelzine, selegiline), or St. John's wort within the last 14 days
  • you are taking certain antiarrhythmics (eg, dronedarone, quinidine, procainamide, amiodarone, sotalol), certain antibiotics (eg, gatifloxacin, moxifloxacin), bedaquiline, escitalopram, a fenfluramine derivative (eg, dexfenfluramine), levomethadyl, methadone, nefazodone, pentamidine, phenothiazines (eg, chlorpromazine, thioridazine), pimozide, serotonin-norepinephrine reuptake inhibitors (SNRIs) (eg, duloxetine, venlafaxine), sibutramine, other SSRIs (eg, fluoxetine, paroxetine), toremifene, or tryptophan

You may have an increased risk of side effects (eg, mental or mood changes, numbness or tingling of the skin, dizziness, confusion, headache, trouble sleeping, unusual tiredness). If you need to stop Celexa, your doctor may need to gradually lower your dose.
  • Continue to take Celexa even if you feel well. Do not miss any doses.
  • If you miss a dose of Celexa, take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.

Ask your health care provider any questions you may have about how to use Celexa.

Important safety information:
