  Description
Amitriptyline Amitriptyline capsule (50 mg) plus a placebo escitalopram tablet will be taken at night half an hour before bedtime. To maximize patient tolerability, in the first 2 weeks the dose of amitriptyline will be 25 mg and then the dose will be increased to 50 mg, but the 25 mg and 50 mg capsules will be indistinguishable to maintain blinding.
Escitalopram Escitalopram tablet (10 mg) plus a placebo amitriptyline capsule will be taken by mouth at night half an hour before bedtime for 12 weeks.
Placebo Placebo escitalopram tablets and placebo amitriptyline capsules will be taken by mouth half an hour before bedtime for 12 weeks.
