Elavil: Amitriptyline inhibits reuptake of serotonin and noradrenaline at central synapses.
When Aygestin is preferred
Aygestin is approved for endometriosis-associated pain, abnormal uterine bleeding due to hormonal imbalance, and secondary amenorrhoea.
When Elavil is preferred
Amitriptyline is approved for major depressive disorder, but contemporary use is dominated by low-dose off-label indications: neuropathic pain, fibromyalgia, chronic tension headache, migraine prevention, irritable bowel syndrome, nocturnal enuresis, and insomnia.
