My vitamin d level is 21. doctor advice to take d rise sachet twice a week for 5 weeks and once a month for a year is it o k?

OK but prob.more...: D rise has 60, 000 iu of vit d3. Taking it 2x/week x 5 weeks should raise levels nicely but once a month averages to 2000 iu/day ; most adults need 5-8000 iu/day to maintain optimal levels of 50-80. Taking a sachet every 10 days would give you an average of 6000 iu/day, a more appropriate dose. See http://bit.Ly/1gnxnk0 ; http://bit.Ly/1ekkvkv ; http://bit.Ly/1dc7vna.
