Desipramine

A small number of children, teenagers, and young adults (up to 24 years of age) who took antidepressants ('mood elevators') such as desipramine during clinical studies became suicidal (thinking about harming or killing oneself or planning or trying to do so). Children, teenagers, and young adults who take antidepressants to treat depression or other mental illnesses may be more likely to become suicidal than children, teenagers, and young adults who do not take antidepressants to treat these conditions. However, experts are not sure about how great this risk is and how much it should be considered in deciding whether a child or teenager should take an antidepressant. Children younger than 18 years of age should not normally take desipramine, but in some cases, a doctor may decide that desipramine is the best medication to treat a child's condition.

You should know that your mental health may change in unexpected ways when you take desipramine or other antidepressants even if you are an adult over age 24. You may become suicidal, especially at the beginning of your treatment and any time that your dose is increased or decreased. You, your family, or your caregiver should call your doctor right away if you experience any of the following symptoms: new or worsening depression; thinking about harming or killing yourself, or planning or trying to do so; extreme worry; agitation; panic attacks; difficulty falling asleep or staying asleep; aggressive behavior; irritability; acting without thinking; severe restlessness; and frenzied abnormal excitement. Be sure that your family or caregiver knows which symptoms may be serious so they can call the doctor if you are unable to seek treatment on your own.

Your healthcare provider will want to see you often while you are taking desipramine, especially at the beginning of your treatment. Be sure to keep all appointments for office visits with your doctor.

The doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with desipramine. Read the information carefully and ask your doctor or pharmacist if you have any questions. You also can obtain the Medication Guide from the FDA website: https://www.fda.gov/Drugs/DrugSafety/ucm085729.htm.

No matter your age, before you take an antidepressant, you, your parent, or your caregiver should talk to your doctor about the risks and benefits of treating your condition with an antidepressant or with other treatments. You should also talk about the risks and benefits of not treating your condition. You should know that having depression or another mental illness greatly increases the risk that you will become suicidal. This risk is higher if you or anyone in your family has or has ever had bipolar disorder (mood that changes from depressed to abnormally excited) or mania (frenzied, abnormally excited mood) or has thought about or attempted suicide. Talk to your doctor about your condition, symptoms, and personal and family medical history. You and your doctor will decide what type of treatment is right for you.

Desipramine is used to treat depression. Desipramine is in a class of medications called tricyclic antidepressants. It works by increasing the amounts of certain natural substances in the brain that are needed for mental balance.

Desipramine comes as a tablet to take by mouth. It is usually taken one or more times a day and may be taken with or without food. Take desipramine at around the same time(s) every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take desipramine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Your doctor may start you on a low dose of desipramine and gradually increase your dose.

It may take 2 to 3 weeks for you to feel the full benefit of desipramine. Continue to take desipramine even if you feel well. Do not stop taking desipramine without talking to your doctor. If you suddenly stop taking desipramine, you may experience withdrawal symptoms such as nausea, headache, and weakness. Your doctor will probably want to decrease your dose gradually.

This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

Before taking desipramine,

• tell your doctor and pharmacist if you are allergic to desipramine, clomipramine (Anafranil), imipramine (Tofranil), trimipramine (Surmontil), any other medications, or any of the ingredients in desipramine tablets. Ask your doctor or pharmacist for a list of the ingredients.
• tell your doctor or pharmacist if you are taking the following medications or have stopped taking them within the past two weeks: monoamine oxidase (MAO) inhibitor such as isocarboxazid (Marplan), linezolid (Zyvox), methylene blue, phenelzine (Nardil), selegiline (Eldepryl, Emsam, Zelapar), and tranylcypromine (Parnate).
• some medications should not be taken with desipramine. Other medications may cause dosing changes or extra monitoring when taken with desipramine. Make sure you have discussed any medications you are currently taking or plan to take before starting desipramine with your doctor and pharmacist. Before starting, stopping, or changing any medications while taking desipramine, please get the advice of your doctor or pharmacist.
• the following nonprescription product may interact with desipramine: cimetidine (Tagamet). Be sure to let your doctor and pharmacist know that you are taking this medication before you start taking desipramine. Do not start this medication while taking desipramine without discussing with your healthcare provider.
• tell your doctor if you have recently had a heart attack. Your doctor may tell you that you should not take desipramine.
• tell your doctor if anyone in your family has or has ever had an irregular heartbeat or has died suddenly. Also tell your doctor if you have or have ever had heart or blood vessel disease such as high blood pressure, atherosclerosis (hardening of the arteries), angina (chest pain), irregular heartbeat, or a heart attack; an enlarged prostate (a male reproductive gland) difficulty urinating; diabetes; seizures; an overactive thyroid gland; schizophrenia (a mental illness that causes disturbed or unusual thinking, loss of interest in life, and strong or inappropriate emotions); or liver or kidney disease.
• tell your doctor if you are pregnant, plan to become pregnant, or are breastfeeding. If you become pregnant while taking desipramine, call your doctor.
• talk to your doctor about the risks and benefits of taking desipramine if you are 65 years of age or older. Older adults should not usually take desipramine because it is not as safe or effective as other medications that can be used to treat the same condition.
• if you are having surgery, including dental surgery, tell the doctor or dentist that you are taking desipramine.
• you should know that this medication may make you drowsy. Do not drive a car or operate machinery until you know how this medication affects you.
• ask your doctor about the safe use of alcohol while you are taking this medication.
• tell your doctor if you use tobacco products. Cigarette smoking may decrease the effectiveness of this medication.
• you should know that desipramine may cause angle-closure glaucoma (a condition where the fluid is suddenly blocked and unable to flow out of the eye causing a quick, severe increase in eye pressure which may lead to a loss of vision). Talk to your doctor about having an eye examination before you start taking this medication. If you have nausea, eye pain, changes in vision, such as seeing colored rings around lights, and swelling or redness in or around the eye, call your doctor or get emergency medical treatment right away.

Unless your doctor tells you otherwise, continue your normal diet.

Take the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.

Keep this medication in the container it came in, tightly closed, and out of the reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location — one that is up and away and out of their sight and reach. https://www.upandaway.org

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (https://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.
