A small number of children, teenagers, and young adults (up to 24 years of age) who took antidepressants ('mood elevators') such as isocarboxazid 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 isocarboxazid, but in some cases, a doctor may decide that isocarboxazid 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 isocarboxazid or other antidepressants even if you are an adult over 24 years of age. 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 isocarboxazid, 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 isocarboxazid. 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: http://www.fda.gov/Drugs/DrugSafety/InformationbyDrugClass/UCM096273.
No matter what 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.
Isocarboxazid is used to treat depression in people who have not been helped by other antidepressants. Isocarboxazid is in a class of medications called monoamine oxidase (MAO) inhibitors. It works by increasing the amounts of certain natural substances in the brain that help maintain mental balance.
Isocarboxazid comes as a tablet to take by mouth. It is usually taken between two and four times a day. Take isocarboxazid at around the same times 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 isocarboxazid exactly as directed.
Swallow the tablets with water or another liquid. If you are unable to swallow the tablets, you can crumble them and swallow the crumbled tablets with food or liquid.
Isocarboxazid may be habit-forming. Do not take a larger dose, take it more often, or take it for a longer period of time than prescribed by your doctor.
Your doctor will probably start you on a low dose of isocarboxazid and gradually increase your dose, not more often than once every 2 to 4 days at first, and then not more often than once every week. After your symptoms improve, your doctor will probably gradually decrease your dose of isocarboxazid.
Isocarboxazid is used to treat depression but does not cure it. It may take 3 to 6 weeks or longer before you feel the full benefit of isocarboxazid. Tell your doctor if your symptoms do not improve during the first 6 weeks of your treatment with isocarboxazid. If your symptoms do improve during your treatment, continue to take isocarboxazid. Do not stop taking isocarboxazid without talking to your doctor.
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
You may experience a serious reaction if you eat foods that are high in tyramine during your treatment with isocarboxazid. Tyramine is found in many foods, including meat, poultry, fish, or cheese that has been smoked, aged, improperly stored, or spoiled; certain fruits, vegetables, and beans; alcoholic beverages; and yeast products that have fermented. Your doctor or dietitian will tell you which foods you must avoid completely, and which foods you may eat in small amounts. You should also avoid foods and drinks that contain caffeine during your treatment with isocarboxazid. Follow these directions carefully. Ask your doctor or dietitian if you have any questions about what you may eat and drink during your treatment.
Take the missed dose as soon as you remember it. However, if it has been more than 2 hours since you were supposed to take the dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.
