Side effects of tricyclic antidepressants

Side effects of tricyclic antidepressants may include:

• Blurred vision.
• Sleepiness
• Dry mouth.
• Upset stomach.
• Dizziness.
• Weight gain.
• Trouble passing stool, called constipation.
• Trouble urinating.
• Heart rhythm issues.
• Trouble having sex.

To lessen or prevent side effects, you may start with a low dose. Your healthcare professional then slowly raises the dose. Most people who take tricyclic antidepressants in low doses have only mild side effects. The doses that work for pain are most often lower than the doses for depression.
