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. MAOIs should only be given 2 to 5 weeks after other
depression medicines have been stopped (so the other medicines are out of the
person's body).2 A child also should not take other
medicines for several days to weeks after stopping treatment with
MAOIs.3
Due to the possibility of serious consequences for the child or
adolescent when taking MAOIs, discuss the dangers as well as any benefits with
your doctor. Be sure to get a list of foods and other medicines your child must
avoid while taking MAOIs.
