WHAT ARE THE SIDE EFFECTS OF THE TRICYCLIC AND MAOI ANTIDEPRESSANTS?

winmentalhealth.com
The side effects of the tricyclics are many, and some can be dangerous. Initially, patients can experience dry mouth, constipation, urinary retention, orthostatic hypotension (sudden lowering of blood pressure upon standing up), blurred vision, tachycardia (increased heart rate), and rarely, cardiac arrhythmias (with high doses). In the long-run, it is common to see weight gain and sexual dysfunction. If one overdoses on these medicines, the result can be fatal.
Common side effects of the MAOIs include orthostatic hypotension, headache, insomnia, weight gain, sexual dysfunction, peripheral edema (swelling), and afternoon sleepiness. If taken with certain forbidden foods or beverages (ones that contain tyramine—including aged cheeses, smoked meats, and certain wines), blood pressure can escalate and lead to a hypertensive crisis and possible stroke. Individuals taking these medications must be on a restricted diet.

Sedation is common in these medications, and some of them help individuals sleep better. Unfortunately, anxiety symptoms may worsen on initiation of these medicines—and any other antidepressants. The initial doses are best started low and slowly increased to therapeutic doses to keep this side effect to a minimum. Some doctors will start patients on a combination of an antidepressant and a benzodiazepine. It takes several weeks for the antidepressant to have an antianxiety or antidepressant effect. The benzodiazepines work quickly and can help the patient until the antidepressant kicks in.
