isocarboxazid oral Warnings
Antidepressant 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. Therefore, 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 immediately 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.
isocarboxazid oral Uses
Isocarboxazid is an antidepressant (monoamine oxidase inhibitor). This medication treats depression by restoring the balance of certain natural substances (neurotransmitters) in the brain. Isocarboxazid can improve your mood and feelings of well-being. Usually, this medication is used in persons who have not responded to treatment with other drugs.How to use isocarboxazid oral
Read the Medication Guide available from your pharmacist before you start using isocarboxazid and each time you get a refill. If you have any questions, consult your doctor or pharmacist.
Take this medication by mouth, usually 2 to 4 times a day as directed by your doctor. This medication may be taken with or without food. Dosage is based on your medical condition and response to therapy and usually will not be more than 60 milligrams per day.
To reduce your risk of side effects, your doctor may start you at a low dose and then gradually increase your dose. Once your condition improves and you are better for a while, your doctor may work with you to reduce your regular dose. Follow your doctor's instructions carefully. Do not take more or less medication or take it more frequently than prescribed. Your condition will not improve any faster and your risk of side effects will increase.

To prevent withdrawal reactions, your doctor may reduce your dose gradually. Consult your doctor or pharmacist for more details, and report any withdrawal reactions immediately.
