Question

Phenelzine is a common MAO inhibitor that has been used to treat depression. It is not, however, prescribed as often as other antidepressants due to its effects on the autonomic nervous system. Describe several side effects that may result from taking phenelzine and explain why they might occur.

Answer 1

Phenelzine, a common MAO inhibitor used to treat depression, can cause side effects such as orthostatic hypotension, dry mouth, blurred vision, constipation, and urinary retention. These side effects occur due to phenelzine's effects on the autonomic nervous system.

Step-by-step explanation:

Phenelzine, a common MAO inhibitor used to treat depression, can cause several side effects due to its effects on the autonomic nervous system. Some of the side effects that may result from taking phenelzine include:

Orthostatic hypotension: This is a drop in blood pressure when changing positions, leading to dizziness or lightheadedness.

Dry mouth: Phenelzine can reduce the production of saliva, resulting in a dry mouth.

Blurred vision: Some individuals may experience blurred vision as a side effect of phenelzine.

Constipation: Phenelzine can slow down the movement of the intestines, leading to constipation.

Urinary retention: In some cases, phenelzine can cause difficulty in emptying the bladder completely.

These side effects occur because phenelzine affects the autonomic nervous system, which controls functions such as blood pressure, salivation, and bowel movements.
