Antidepressants are medications that help maintain the chemical levels in the brain called neurotransmitters (serotonin-nor epinephrine - dopamine). Patients must take medications regularly for 3 to 4 weeks before you see results. Antidepressants may cause side effects such as headache, nausea, insomnia, sexual problems, among others.
They are not sedatives, tranquilizers, or addictive.
