What is the correct interpretation of 1gtt tid OU?

The phrase "1gtt tid OU" breaks down as follows: "1gtt" means one drop, "tid" stands for three times a day, and "OU" is the abbreviation for both eyes. Therefore, the correct interpretation is that one drop is to be administered to both eyes three times a day.

Understanding the abbreviations is crucial for interpreting medical prescriptions accurately. "Gtt" specifically refers to drops, commonly used in ophthalmic prescriptions, and "tid" clarifies the frequency of administration. "OU" indicates that the treatment is intended for both eyes rather than just one, which is why the correct interpretation emphasizes administering the drops to both eyes.

This knowledge is important in ensuring that patients follow their prescribed treatment regimens correctly, thereby enhancing the effectiveness of their care.
