IsocarboxazidMedical AlertYour condition can cause complications in a medical emergency. For information about enrolling in MedicAlert, call 1-888-633-4298 (US) or 1-800-668-1507 (Canada). WarningAntidepressant medications are used to treat a variety of conditions, including depression and other mental/mood disorders. These medications can help prevent suicidal thoughts/attempts and provide other important benefits. However, studies have shown that a small number of people (especially people younger than 25) who take antidepressants for any condition may experience worsening depression, other mental/mood symptoms, or suicidal thoughts/attempts. It is very important to talk with the doctor about the risks and benefits of antidepressant medication (especially for people younger than 25), even if treatment is not for a mental/mood condition. Tell the doctor right away if you notice worsening depression/other psychiatric conditions, unusual behavior changes (including possible suicidal thoughts/attempts), or other mental/mood changes (including new/worsening anxiety, panic attacks, trouble sleeping, irritability, hostile/angry feelings, impulsive actions, severe restlessness, very rapid speech). Be especially watchful for these symptoms when a new antidepressant is started or when the dose is changed. PrecautionsBefore taking isocarboxazid, tell your doctor or pharmacist if you are allergic to it; or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details. Before using this medication, tell your doctor or pharmacist your medical history, especially of: a certain adrenal gland tumor (pheochromocytoma), cerebrovascular disease (such as stroke), high blood pressure, history of severe/frequent headaches, liver problems, personal/family history of mental/mood disorders (such as schizophrenia, bipolar disorder), heart disease (such as heart failure, heart attack, coronary artery disease), kidney disease, certain nervous system diseases (Parkinson's syndrome, seizures), overactive thyroid (hyperthyroidism), personal/family history of glaucoma (angle-closure type). This drug may make you dizzy or drowsy. Alcohol or marijuana (cannabis) can make you more dizzy or drowsy. Do not drive, use machinery, or do anything that needs alertness until you can do it safely. Avoid alcoholic beverages. Talk to your doctor if you are using marijuana (cannabis). Before having surgery or any procedures requiring use of contrast dye (such as myelography), tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products). You may need to stop taking this drug beforehand. Follow your doctor's instructions carefully. If you have heart disease, this medication may mask chest pain. Avoid strenuous exercise while taking this medication. If you have diabetes, isocarboxazid may lower your blood sugar. Check your blood sugar regularly as directed and share the results with your doctor. Tell your doctor right away if you have symptoms of low blood sugar such as sudden sweating, shaking, fast heartbeat, hunger, blurred vision, dizziness, or tingling hands/feet. Your doctor may need to adjust your diabetes medication, exercise program, or diet. Older adults may be more sensitive to the side effects of this drug, especially the effects on blood pressure. During pregnancy, this medication should be used only when clearly needed. Discuss the risks and benefits with your doctor. Since untreated mental/mood problems (such as depression) can be a serious condition, do not stop taking this medication unless directed by your doctor. If you are planning pregnancy, become pregnant, or think you may be pregnant, immediately discuss with your doctor the benefits and risks of using this medication during pregnancy. It is unknown if this drug passes into breast milk. Consult your doctor before breastfeeding. Side EffectsSee also Warning section. Dizziness, drowsiness, tiredness, weakness, problems sleeping, constipation, and dry mouth may occur. If any of these effects last or get worse, notify your doctor or pharmacist promptly. To reduce the risk of dizziness and lightheadedness, get up slowly when rising from a sitting or lying position. Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects. Tell your doctor right away if you have any serious side effects, including: fainting, mental/mood changes (such as agitation, confusion), muscle stiffness, changes in sexual ability/interest, shaking (tremor), shivering, swollen ankles/legs, unusual weight gain, eye pain/swelling/redness, vision changes (such as double/blurred vision), signs of liver problems (such as nausea/vomiting that doesn't stop, stomach/abdominal pain, yellowing eyes/skin, dark urine), seizures. This drug may rarely cause an attack of extremely high blood pressure (hypertensive crisis), which may be fatal. Many drug and food interactions can increase this risk (See also Drug Interaction section.) Stop taking isocarboxazid and get medical help right away if any of these serious side effects occur: frequent/severe headache, fast/slow/irregular/pounding heartbeat, chest pain, neck stiffness/soreness, severe nausea/vomiting, sweating/clammy skin (sometimes with fever), widened pupils, sudden sensitivity to light (photophobia). This medication may increase serotonin and rarely cause a very serious condition called serotonin syndrome/toxicity. The risk increases if you are also taking other drugs that increase serotonin, so tell your doctor or pharmacist of all the drugs you take (see Drug Interactions section).
