What is Desipramine?

Antidepressants increased the risk of suicidal thinking and behavior in children, adolescents, and young adults in short-term studies with major depressive disorder and other psychiatric disorders. Short-term studies did not show an increase in the risk of suicidality with antidepressants compared with placebo in adults beyond age 24, and there was a reduction in risk with antidepressants compared with placebo in adults aged 65 or older. Risk in children, adolescents, and young adults must be balanced with the clinical need. Monitor patients closely for clinical worsening, suicidality, or unusual changes in behavior. Families and caregivers should be advised of the need for close observation and communication with the prescriber. Desipramine hydrochloride is not approved for use in pediatric patients .

Desipramine is used to treat depression. It works by increasing the activity of a chemical called norepinephrine in the brain. This medicine is a tricyclic antidepressant.

This medicine is available only with your doctor's prescription.

Tell your doctor if you are also using other medicine to treat depression, such as amitriptyline, citalopram, fluoxetine, nortriptyline, paroxetine, or sertraline. You must wait at least 5 weeks after you stop using fluoxetine before you can start using desipramine.

The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:

Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Appropriate studies have not been performed on the relationship of age to the effects of desipramine in the pediatric population. Safety and efficacy have not been established.

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of desipramine in the elderly. However, elderly patients are more likely to have confusion, falling episodes, and age-related kidney problems, which may require an adjustment in the dose for patients receiving desipramine.

There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.

For some teenagers and young adults, this medicine can increase thoughts of suicide. Tell your doctor right away if you start to feel more depressed and have thoughts about hurting yourself. Report any unusual thoughts or behaviors that trouble you, especially if they are new or are getting worse quickly. Make sure the doctor knows if you have trouble sleeping, get upset easily, have a big increase in energy, or start to act reckless. Tell the doctor if you have sudden or strong feelings, such as feeling nervous, angry, restless, violent, or scared. Let the doctor know if you or anyone in your family has bipolar disorder (manic-depressive) or has tried to commit suicide.

Do not take desipramine with a monoamine oxidase (MAO) inhibitor (eg, isocarboxazid [Marplan®], phenelzine [Nardil®], selegiline [Eldepryl®], tranylcypromine [Parnate®]). Do not start taking desipramine during the 2 weeks after you stop a MAO inhibitor and wait 2 weeks after stopping desipramine before you start taking a MAO inhibitor. If you take them together or do not wait 2 weeks, you may develop confusion, agitation, restlessness, stomach or intestinal symptoms, a sudden high body temperature, an extremely high blood pressure, or severe convulsions.

Desipramine may cause a serious condition called serotonin syndrome if taken together with some medicines. Do not use desipramine with buspirone (Buspar®), fentanyl (Abstral®, Duragesic®), linezolid (Zyvox®), lithium (Eskalith®, Lithobid®), methylene blue, tryptophan, St. John's wort, or some pain or migraine medicines (eg, sumatriptan, tramadol, Frova®, Maxalt®, Relpax®, Zomig®). Check with your doctor first before taking any other medicines with desipramine.

Do not stop taking this medicine without first checking with your doctor. Your doctor may want you to reduce gradually the amount you are using before stopping completely. This may help prevent a possible worsening of your condition and reduce the possibility of withdrawal symptoms such as headache, nausea, or a general feeling of discomfort or illness.
