Tricyclic antidepressant (TCA)
Amitriptyline dosage guide: how much to take and when
Choosing the right dose of Amitriptyline (Amitriptyline) is the most important practical decision after starting therapy. Amitriptyline is supplied as tablet in 10mg, 25mg, 50mg, 75mg, 100mg, and the right dose for a given person depends on the indication, age, comorbidities and tolerance to the active ingredient Amitriptyline.
Starting dose and titration
According to the prescribing information, most adults begin Amitriptyline at the lowest available strength of 10mg, 25mg, 50mg, 75mg, 100mg and titrate up only if symptom control is insufficient and tolerability is good. Higher doses are reserved for selected cases. Older adults, people with renal or hepatic impairment, and those taking interacting medications should usually start at the lowest dose.
When to adjust
Dose adjustment is guided by symptom response and side effect burden, not by arbitrary schedules. Amitriptyline inhibits the reuptake of serotonin and noradrenaline at central synapses, raising synaptic levels of both neurotransmitters. If side effects are limiting at a given dose, going down a step is usually preferred over stopping abruptly. If the response is incomplete after several weeks, a higher dose can be tried under medical supervision.
