Antidepressants increased the risk of suicidal thinking and behavior in children, adolescents, and young adults in short-term studies with major depressive disorder (MDD) and other psychiatric disorders. Short term studies did not show an increase in the risk of suicidality with antidepressants compared to placebo in adults beyond age 24, and there was a reduction in risk with antidepressants compared to placebo in adults aged 65 and older. This risk must be balanced with the clinical need. Monitor patients closely for clinical worsening, suicidality, or unusual changes in behavior. Families and caregivers should be advised of the need for close observation and communication with the prescriber. Not approved for use in pediatric patients .

Sometimes maprotiline must be taken for up to two or three weeks before you begin to feel better. Your doctor should check your progress at regular visits.
The dose of maprotiline will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of maprotiline. If your dose is different, do not change it unless your doctor tells you to do so.
The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.

Precautions While Using maprotiline
It is very important that your doctor check your progress at regular visits. This will allow your dosage to be changed if necessary and will help to reduce side effects.
Maprotiline will add to the effects of alcohol and other CNS depressants (medicines that slow down the nervous system, possibly causing drowsiness). Some examples of CNS depressants are antihistamines or medicine for hay fever, other allergies, or colds; sedatives, tranquilizers, or sleeping medicine; prescription pain medicine or narcotics; barbiturates; medicine for seizures; or anesthetics, including some dental anesthetics. Check with your doctor before taking any of the above while you are using maprotiline .
Maprotiline may cause some people to be agitated, irritable or display other abnormal behaviors. It may also cause some people to have suicidal thoughts and tendencies or to become more depressed. If you or your caregiver notice any of these adverse effects, tell your doctor right away.
Maprotiline may cause blurred vision, especially during the first few weeks of treatment. It may also cause some people to become drowsy or less alert than they are normally. If these effects occur, do not drive, use machines, or do anything else that could be dangerous if you are not alert or able to see well.
Dizziness, lightheadedness, or fainting may occur, especially when you get up from a lying or sitting position. Getting up slowly may help. If this problem continues or gets worse, check with your doctor.
Maprotiline may cause dryness of the mouth. For temporary relief, use sugarless gum or candy, melt bits of ice in your mouth, or use a saliva substitute. However, if your mouth continues to feel dry for more than 2 weeks, check with your medical doctor or dentist. Continuing dryness of the mouth may increase the chance of dental disease, including tooth decay, gum disease, and fungus infections.
Before having any kind of surgery, dental treatment, or emergency treatment, tell the medical doctor or dentist in charge that you are using maprotiline. Taking maprotiline together with medicines that are used during surgery or dental or emergency treatments may increase the CNS depressant effects.
Do not stop taking maprotiline without first checking with your doctor. Your doctor may want you to reduce gradually the amount you are taking before stopping completely. This will allow your body to adjust properly and will reduce the possibility of unwanted effects.
