Monoamine oxidase inhibitors (MAOIs) are very rarely given
to children or teens and usually are not the first medicines given to treat
their
depression. This is because these medicines have
serious side effects when combined with certain foods or medicines.
Moclobemide, a reversible MAOI not available in the United States, is the only
MAOI with some evidence to support its use in the treatment of childhood
depression.1 No evidence exists that other MAOIs are
effective at treating depression in young people, although they are sometimes
used when other medicines have failed.
Examples of MAOIs that have
been used to treat depression in children and teens include:
- Phenelzine (Nardil).
- Tranylcypromine
(Parnate).
- Moclobemide (Manerix, Aurorix). This drug is not available in the
United States.
MAOIs sometimes are used to treat unusual symptoms of
depression, such as a heavy feeling in the arms and legs or feeling "slowed
down."
Side effects of MAOIs can include:
- Difficulty getting to
sleep.
- Dizziness, lightheadedness, and fainting.
- Dry
mouth, blurred vision, and appetite changes.
- High blood pressure
and changes in heart rate and rhythm.
- Muscle twitching and feelings
of restlessness.
- Weight gain.
- Negative interactions
with other medicines and some foods.
MAOIs must be discontinued gradually to reduce the chance of
withdrawal symptoms. Some drugs must not be used along with MAOIs because
serious, sometimes fatal, reactions can occur. Your child will need to wait
several weeks after stopping MAOI treatment before starting other drugs.
Certain nonprescription medicines should be avoided, including certain
cold remedies and diet pills. Your child must wait at least 14 days after
stopping MAOIs before taking another antidepressant.
Serious
consequences are possible for the child or teen who takes MAOIs. So discuss
with your doctor the dangers and the benefits of MAOIs. Be sure to get a list
of foods and other medicines your child must avoid while taking MAOIs.
