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. 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.
This medication is used to treat depression. It works by restoring the balance of certain natural substances (neurotransmitters) in the brain. Moclobemide can improve your mood and feelings of well-being. It belongs to a class of drugs known as monoamine oxidase (MAO) inhibitors. Usually, this medication is used in persons who have not responded to treatment with other drugs.
Take this medication by mouth, usually twice daily immediately after meals or as directed by your doctor. Dosage is based on your medical condition and response to treatment.
To reduce your risk of side effects, your doctor may start you at a low dose and 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.
Use this medication regularly in order to get the most benefit from it. To help you remember, use it at the same times each day. It may take several weeks for the full benefits of this medication to be noticed. Do not stop taking this medication without consulting your doctor.
If you suddenly stop using this medication, you may have withdrawal symptoms (such as restlessness, confusion, hallucinations, headache, weakness, and diarrhea). To help prevent withdrawal, your doctor may lower your dose slowly. Withdrawal is more likely if you have used moclobemide for a long time or in high doses. Tell your doctor or pharmacist right away if you have withdrawal.
Tell your doctor if your condition lasts or gets worse.

Tell your doctor or pharmacist if you are using any of these medications before, during, or within 2 weeks after treatment with moclobemide. Tell your doctor or pharmacist if you have taken fluoxetine during at least 5 weeks before starting moclobemide. Discuss with your doctor how much time to wait between starting or stopping any of these drugs and taking moclobemide.
Other medications can affect the removal of moclobemide from your body, which may affect how moclobemide works. Examples include azole antifungals (such as itraconazole), cimetidine, macrolide antibiotics (such as erythromycin), rifamycins (such as rifabutin), ritonavir, St. John's wort, drugs used to treat seizures (such as carbamazepine, phenytoin), among others.

Check the labels on all your medicines (such as allergy, cough-and-cold products, diet pills) because they may contain dextromethorphan, decongestants, stimulants, or ingredients that may cause drowsiness. Ask your pharmacist about using those products safely.
Depending on your medical history, your doctor may direct you to restrict your dietary intake of tyramine during and for 2 weeks after stopping the use of moclobemide. Certain foods and beverages are high in tyramine. Consult your doctor or pharmacist for more details if needed.
Patients taking other MAO inhibitors (such as phenelzine, isocarboxazid) without restricting the amount of tyramine in their diets have experienced very serious (sometimes fatal) attacks of very high blood pressure. Tell your doctor right away if you develop symptoms of high blood pressure such as fast/slow heartbeat, vomiting, sweating, headache, chest pain, sudden vision changes, weakness on one side of the body, stiff neck, or trouble speaking.
