What does this mean: 1 gtt OU bid

[BellKicker]

I'm thinking it means a drop in both eyes. bid I can't figure out. How about tid/qid?

I'm sorry, it's probably a stupid question but if someone tells me I'll never ask again.

Thanks.

I don't know about the beginning but bid means twice a day.

Thanks a lot.

I thought it had to be something like that. I know guttatum is latin for drop so gtt=drop makes sense.

How's OU both eyes? Oculi Universalis or something?

BID/TID/QID I won't even think about. At least I know.

Thanks again.

o.d. -- oculus dexter, right eye
o.s. -- oculus sinister, left eye
o.u. -- oculus uterque, each eye

My orgo professor said that anyone who is left-handed must be sinister, and since then I've never had a problem remembering o.d./o.s.

b.i.d. = bis in die (Latin meaning twice a day)
t.i.d. = ter in die (latin for 3 times a day)
q.i.d. = quater in die (latin for 4 times a day)
q.d. = quaque die latin meaning every day
hope this helps!
