History of Changes

Purpose

While treating depression, significant numbers respond poorly to anti-depressants; one cause is vitamin B12 deficiency. The investigators are conducting an open label randomized controlled trial to investigate difference in response to SSRI monotherapy alone versus SSRI and intramuscular B12 replacement in people with low-normal B12 levels. 300 participants will be allocated to each arm of intervention at out patient clinics of the department of Psychiatry at Aga Khan University Hospital, Karachi Pakistan. Baseline and 3 month measurement of depression will be on Hamilton Rating Scale for Depression (Urdu version) and response rates compared.

Estimated Primary Completion Date:	June 2010 (Final data collection date for primary outcome measure)

Arms	Assigned Interventions
Active Comparator: Vitamin B12 with antidepressants Subjects in this arm will receive vitamin B12 supplement (injectable)along with their routine antidepressant treatment as prescribed by their primary physicians. subjects will be blind to their arm allocation and will receive injections in a concealed manner with injection vials covered with foil.	Dietary Supplement: Vitamin B12 Vitamin B12 injections containing methylcobalamin 1000 mcg given once every six months along with the routine antidepressant treatment. Other Name: Injection Bevidox intramuscular
Placebo Comparator: Placebo injections dextrose water Subjects in this arm will receive placebo injections which will contain only dextrose water. They will also receive 6 injections on a weekly basis and the injection vials will be covered with foil to ensure masking.
