When Viagra is preferred
The medication is indicated in adult men for the treatment of erectile dysfunction, defined as the inability to achieve or maintain a penile erection sufficient for sexual activity.
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.
