Tolerance to these adverse effects of these drugs often develops if treatment is continued.Side effects may also be less troublesome if treatment is initiated with low doses and then gradually increased, although this may also delay the beneficial effects.They are also effective in migraine prophylaxis, though not in the instant relief of an acute migraine attack.They may also be effective to prevent chronic tension headaches.The severe morbidity and mortality associated with these drugs is well documented due to their cardiovascular and neurological toxicity.Additionally, it is a serious problem in the pediatric population due to their inherent toxicity and the availability of these in the home when prescribed for bed-wetting and depression.New research has also revealed compelling evidence of a link between long-term use of anticholinergic medications like TCAs and dementia.

The precise mechanism of action in explanation of their analgesic efficacy is unclear, but it is thought that they indirectly modulate the opioid system in the brain downstream via serotonergic and noradrenergic neuromodulation, among other properties.Many side effects may be related to the antimuscarinic properties of the TCAs.Such side effects are relatively common and may include dry mouth, dry nose, blurry vision, lowered gastrointestinal motility or constipation, urinary retention, cognitive and/or memory impairment, and increased body temperature.TCAs can behave like class 1A antiarrhythmics, as such, they can theoretically terminate ventricular fibrillation, decrease cardiac contractility and increase collateral blood circulation to ischemic heart muscle.Naturally, in overdose, they can be cardiotoxic, prolonging heart rhythms and increasing myocardial irritability.

Newer antidepressants are thought to have fewer and less severe side effects and are also thought to be less likely to result in injury or death if used in a suicide attempt, as the doses required for clinical treatment and potentially lethal overdose (see therapeutic index) are far wider in comparison.
