Citalopram- Half Life: 35 hours; Schedule IV Drug
Celexa (Citalopram) is a prescription antidepressant drug used to treat depression associated with mood disorders. In certain cases citalopram is used in the treatment of anxiety if other medications do not work. Citalopram belongs to a class of drugs known as selective serotonin reuptake inhibitors (SSRIs). This drug may need to be taken for up to 4 weeks or longer before it starts to work as it differs person to person.

Citalopram is generally well-tolerated in patients taking therapeutic doses ranging from 20 to 60 mg a day. Regardless of how strong a SSRI is, patients should always be monitored when taking them. While Citalopram is taken by people of all ages, it is one of the main SSRIs that is given to elderly patients who need them. Citalopram works by increasing the amount of serotonin (a natural substance in the brain) that helps maintain mental balance.
Investigational studies have found that citalopram significantly reduces the symptoms of diabetic neuropathy and premature ejaculation. There is also evidence that it may even treat post-stroke pathological crying. There are other medications that treat these conditions- however, if those medications do not work, a doctor may simply prescribe a low dosage to see if citalopram has any effect.
As stated earlier, citalopram is generally well-tolerated by patients taking it, so side effects shouldn’t be too much of a nuisance. Medications work differently on every person, so there are no guarantees that citalopram will agree with you or not, so contact your doctor if there are any concerns when taking the medication.
Citalopram is listed as a Schedule IV drug of the United States’ Controlled Substances Act which means that even though it has a low potential for abuse, it can be still abused. Do not stop taking citalopram without consulting your doctor first as the potential for withdrawal symptoms may occur if too much of the drug is taken or if the drug is taken for too long.
Side effects of citalopram cannot be anticipated, but if any develop or change in intensity, be sure to inform your doctor as soon as possible. Only your doctor can determine whether or not it is safe to continue taking citalopram. Side effects are as followed:
Nausea; dry mouth, gas; loss of appetite; diarrhea; insomnia; drowsiness; dizziness; trouble concentrating; feeling nervous, restless, or unable to sit still; weight changes; frequent urination; decreased sex drive; impotence; difficulty having an orgasm; dry or watery mouth; yawning; ringing in your ears
If any of these more serious side effects are experienced, be sure to contact your doctor as soon as possible:
Seizures; tremors; muscle stiffness; twitching; shivering; problems with balance and/or coordination; feeling agitated; confusion; excessive sweating; increased heartbeat
Citalopram, just like any other drug can cause withdrawal symptoms. Citalopram withdrawal symptoms tend to begin within eight hours of the last dose taken and can last anywhere from one to eight weeks. This highly depends on how much was taken and differs from person to person. If you or someone you know has stopped using citalopram, the best advice would be to taper slowly rather than stop suddenly. Antidepressant withdrawal happens to be one of the more uncomfortable types of withdrawal- not that any type of withdrawal is comfortable, but with citalopram, there are many different symptoms that include but are not limited to:
Anxiety; dizziness; headache; fatigue; insomnia; tremors; hallucinations; nausea; vomiting; diarrhea; restlessness; blurred vision; muscle/joint pain; tingling sensations; fever; abdominal discomfort; anorexia; agitation; vertigo; excessive sweating; irritability; aggression; insomnia; confusion; nightmares; chills; hot flashes; trouble concentrating; crying spells; thoughts of suicide; lethargy; weakness; flu symptoms
Now a doctor prescribes these types of medications to patients who need them, but there are times where a patient might not quite listen to a doctor when he/she tells them to take it as prescribed. If one goes overboard, they are going to feel the effects of withdrawal, but even a person that has been taking an antidepressant like citalopram for a period over a couple of years, they will even need to taper off of the drug because they have built up a natural tolerance to the drug.
