In a prescription such as this:
omeprazole 20 mg BID
I know BID means two times per day.
However, does this mean to take half the dose of 20 mg (10 mg) in the morning plus 10 mg in the evening?
Or does it mean to take the full dose (20 mg) in the morning plus 20 mg in the evening?
As you've stated BID = bis in die = twice a day. According to a standard dosage sheet from the University of Florida, BID = every 12 hours.
However, I was reading a forum for nurses [See References] and there seems to be variations on BID (roughly 8-12 hours apart) depending on the hospital.
If possible, contact your nurse/physician for the clearest clarification.
