# Amitriptyline Hydrochloride 25 mg ## SHORT DESCRIPTION Amitriptyline Hydrochloride 25 mg is a **tricyclic antidepressant (TCA)** medicine. Although originally developed to treat depression, it is also commonly prescribed at lower doses for certain types of **nerve pain**, migraine prevention and other conditions when clinically appropriate. Amitriptyline affects neurotransmitters such as **serotonin and norepinephrine** in the brain and nervous system. It can also have sedative and anticholinergic effects. ## KEY BENEFITS * Helps manage **certain types of nerve pain** * May help reduce symptoms of depression when prescribed at an appropriate dose * May help prevent certain types of migraine * Can improve sleep when pain or other conditions interfere with sleep * May help reduce persistent pain associated with some chronic conditions * Provides effects on serotonin and norepinephrine pathways involved in mood and pain processing ## USES / INDICATIONS Amitriptyline Hydrochloride 25 mg may be prescribed for: * **Depression** * Neuropathic or nerve pain * Certain chronic pain conditions * Prevention of migraine or recurrent headache in selected patients * Certain sleep problems when associated with an underlying condition, when prescribed by a healthcare professional The appropriate indication and dose depend on the patient's condition. ## HOW IT WORKS Amitriptyline inhibits the reuptake of **serotonin and norepinephrine** in the nervous system. This increases the activity of these neurotransmitters and contributes to its antidepressant and pain-modulating effects. It also acts on several other receptors, which contributes to effects such as: * Sedation * Dry mouth * Reduced intestinal activity * Changes in heart rate For nerve pain, its effects on pain-processing pathways can reduce abnormal pain signaling even when the patient does not have depression. ## DOSAGE & ADMINISTRATION * Take Amitriptyline 25 mg exactly as prescribed. * It is commonly taken **once daily**, often in the evening because it can cause drowsiness. * Swallow the tablet with water. * It can generally be taken with or without food. * Take it at approximately the same time each day. * Do not increase or decrease the dose without medical advice. * Do not stop long-term treatment suddenly without consulting your doctor.
