My nurse told me that it is ok to make a phone call between 8: 00 and 12: 00, not at the same time, but in theory, the interval of drug action is almost good. I will make a phone call myself from 8: 30 to 9: 00, but the time will be delayed every time I go to the hospital for B-ultrasound to refill my medicine and injection, so I have to call 10: 00. Please try your best to pay attention to yourself.
