How does this medication work? What will it do for me?

Maprotiline belongs to a class of medications called tetracyclic antidepressants. This medication is used to treat depression, anxiety related to depression, and nerve pain. Depression is believed to be caused by imbalances in certain brain chemicals. This medication works by bringing these chemicals back into balance. Because brain chemicals are also involved in sending pain signals, this medication is believed to help with nerve pain by changing the balance of these chemicals.

Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.

Bladder problems: Maprotiline may cause urine retention and difficulty in urinating. If you have bladder problems, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Contact lenses: Since this medication can reduce tear production, contact lenses may damage the cornea of the eye. Talk to your doctor or optometrist about wearing contact lenses while talking maprotiline.

Drowsiness/reduced alertness: Maprotiline may reduce the mental or physical abilities required to perform certain tasks, such as operating machinery or driving a motor vehicle. Avoid these activities until you are sure that the medication does not affect you in this way.

Enlarged prostate: This medication can cause increased difficulty with urination, which may make symptoms of an enlarged prostate gland more pronounced. If you have an enlarged prostate or other difficulties with urinary disorders, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Glaucoma: This medication can cause the effects of glaucoma to worsen. If you have glaucoma, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Heart conditions: Maprotiline, particularly when taken in high doses, can cause abnormal heart rhythms, heart attack, or stroke.

Mental Health: Maprotiline may cause people with schizophrenia to experience psychosis and can trigger manic episodes when it is taken by someone with bipolar depression. It can also worsen thought disturbances for people who have psychotic conditions. If you experience symptoms such as hallucinations, mania (feeling unusually over-excited or uninhibited), or delusional thinking, or notice them in a family member who is taking this medication, contact your doctor as soon as possible.

Like other antidepressant medications, it may cause people with depression to want to hurt themselves or others, particularly before the feelings of depression start to ease. These symptoms may occur within several weeks after starting this medication. If you experience these side effects or notice them in a family member who is taking this medication, contact your doctor immediately. You should be closely monitored by your doctor for emotional and behaviour changes while taking this medication.

Mouth care: Maprotiline causes dry mouth and decreased body secretions, which may result in an increased risk of cavities. Talk to your dentist about how to keep your mouth healthy while taking maprotiline.

  • irritability
  • low blood pressure
  • nausea

  • vomiting
  • worsening depression

Thyroid disease: Maprotiline can increase the heart and blood pressure effects that occur when the thyroid gland is overactive. If you have a thyroid condition, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.
