What does the abbreviation gtt stand for in medication labeling?

• A. Gram total
• B. Giga ton
• C. Drops
• D. Guttation

Answer: (C)

The term gtt is used in medication labeling to indicate the number of drops to administer. It comes from the Latin gutta, meaning a drop, and is commonly used for liquid meds given by a dropper, such as eye or ear preparations. This makes the correct interpretation clearly “drops,” since the instruction specifies a volume measured by drops rather than by weight. The other options don’t fit: grams would be written as g and refer to weight, giga ton isn’t a medical dosing unit, and guttation is a plant process, not related to how meds are dosed. In practice, the exact volume of a drop can vary by bottle, so the label focuses on the count of drops rather than a precise milliliter measurement.
