Nu-Citalopram: Uses, Side Effects and Dosage

ABOUT THIS MEDICATION

What the medication is used for:

Nu-Citalopram has been prescribed to you by your doctor to relieve your symptoms of depression. Treatment with these types of medications is most safe and effective when you and your doctor have good communication about how you are feeling.

What it does:

Nu-Citalopram belongs to a group of medicines known as antidepressants, more specifically to the family of medicines called SSRIs (Selective Serotonin Reuptake Inhibitors).

Nu-Citalopram is thought to work by increasing the levels of a chemical in the brain called serotonin (5-

hydroxytryptamine).

When it should not be used:

• Do not use Nu-Citalopram at the same time as pimozide.

• Do not use Nu-Citalopram if you are currently or have

  recently taken monoamine oxidase antidepressants (e.g. selegiline, moclobemide).

• Do not take Nu-Citalopram if you are allergic to it, or to

  any of the components of its formulation (for list of ingredients see below).

• Stop taking Nu-Citalopram and contact your doctor

  immediately if you experience an allergic reaction or any severe side effect.

• Do not use Nu-Citalopram if you have been diagnosed

  with a congenital long QT syndrome

citalopram hydrobromide

What the nonmedicinal ingredients are:

Croscarmellose sodium, hydroxyethyl cellulose, lactose monohydrate, magnesium stearate, microcrystalline cellulose, polyethylene glycol and titanium dioxide.

What dosage forms it comes in:

Nu-Citalopram is available as 20 mg, or 40 mg tablets in unit dose and bottles.

WARNINGS AND PRECAUTIONS

Treatment with these types of medications is most safe and effective when you and your doctor have good communication about how you are feeling.

Nu-Citalopram is not for use in children under 18 years of age.

New or Worsened Emotional or Behavioural Problems

Particularly in the first few weeks or when doses are adjusted, a small number of patients taking drugs of this type may feel worse instead of better; for example, they may experience unusual feelings of agitation, hostility or anxiety, or have impulsive or disturbing thoughts such as thoughts of self-harm or harm to others. Should this happen to you, or to those in your care if you are a caregiver or guardian, consult your doctor immediately. Close observation by a doctor is necessary in this situation. Do not discontinue your medication on your own.

Effects on Pregnancy and Newborns

If you are already taking/using Nu-Citalopram and have just found out that you are pregnant, you should talk to your doctor immediately. You should also talk to your doctor if you are planning to become pregnant.

Possible complications at birth (from taking any newer antidepressant, including Nu-Citalopram): Post-marketing reports indicate that some newborns whose mothers took an SSRI (Selective Serotonin Reuptake Inhibitor) such as Nu-Citalopram or other newer antidepressant during pregnancy have developed complications at birth requiring prolonged hospitalisation, breathing support and tube feeding. Reported symptoms include: feeding and/or breathing difficulties, seizures, tense or overly relaxed muscles, jitteriness and constant crying. In most cases, the newer antidepressant was taken during the third trimester of pregnancy. These symptoms are consistent with either a direct adverse effect of the antidepressant on the baby, or possibly a discontinuation syndrome caused by sudden withdrawal from the drug. These symptoms normally resolve over time. However, if your baby experiences any of these symptoms, contact your doctor as soon as you can. Persistent Pulmonary Hypertension of the Newborn (PPHN) and newer antidepressants:

Preliminary information suggests that use of SSRIs during the second half of pregnancy may be associated with an increased rate of a serious lung condition called persistent pulmonary hypertension of the newborn (PPHN) that causes breathing difficulties in newborns soon after birth. According to the study, babies born with this condition were 6 times more likely than healthy babies to have been exposed to SSRIs. In the general population, PPHN is known to occur at a rate of about 1-2 per 1000 newborns.

If you are pregnant and taking an SSRI, or other newer antidepressant, you should discuss the risks and benefits of the various treatment options with your doctor. It is very important that you do NOT stop taking these medications without first consulting your doctor.

Risk of Bone Fractures:

An increased risk of bone fractures has been observed in patients, mainly 50 years of age and older, taking this type of medicines.

Before you use Nu-Citalopram, tell your doctor or pharmacist:

• All your medical conditions, including heart problems,

  history of seizures, manic-depressive illness, liver or kidney disease, diabetes or history of bleeding disorders.

• If you have QT/QTc prolongation or a family history of

  QT/QTc prolongation.

• If you have a personal history of fainting spells.

• If you have a family history of sudden cardiac death at

  <50 years.

• If you have electrolyte disturbances (e.g., low blood

  potassium, magnesium, or calcium levels) or conditions that could lead to electrolyte disturbances (e.g., vomiting, diarrhea, dehydration).

• If you have an eating disorder or are following a strict

  diet.

• If you had recent bone fractures or were told you have

  osteoporosis or risk factors for osteoporosis.

• If you are pregnant or thinking about becoming

  pregnant, or if you are breast feeding.

• Any medications (prescription or non-prescription)

  which you are taking or have taken within the last 14 days, especially monoamine oxidase inhibitors, pimozide, any other antidepressants, triptans used to

  treat migraines, lithium, tramadol or drugs containing tryptophan.

  • Your habits of alcohol and /or street drug consumption.

  • Any natural or herbal products you are taking (e.g. St.

    John’s Wort.
