What are the side effects of trimipramine?

Trimipramine, like other antidepressant medications, may increase the risk for suicidal thoughts and behavior, especially in children, teenagers, and young adults. A person with increased suicidal tendencies may be more anxious, restless, hostile, or irritable, and may act impulsively or suffer panic attacks. Talk to your doctor immediately if you notice any changes in mood of a person taking trimipramine.
Seek immediate medical attention if you experience serious side effects, including palpitations, chest pain, sweating, sudden numbness or weakness, confusion, problems with balance and speech, hallucinations, seizures, fainting, bleeding or bruising, changes in urination, facial muscle spasms, eye pain, changes in vision or swelling or redness in the eye, and extreme thirst.
Less serious side effects of trimipramine may include nausea, vomiting, loss of appetite, constipation, diarrhea, decreased sex drive, rash, fever, headache, dry mouth, and numbness, weakness, or tingling. Tell your doctor if these side effects worsen or become bothersome.
