The medical abbreviation "gtt" is a common shorthand used in prescriptions and medical records. It doesn't specifically mean eye drops, but rather signifies a unit of volume – a drop. So, when you see "gtt" in a prescription, it's indicating the administration of medication by drops. Let's explore this further and delve into some frequently asked questions.
What does GTT mean in medical terms?
GTT stands for "guttae," the Latin plural of "gutta," meaning "drop." In a medical context, particularly in prescriptions or charts, "gtt" specifies that a medication should be administered as drops, be it for eyes, ears, or nose. It's a concise way to express dosage.
Is GTT always for eye drops?
No, "gtt" isn't exclusively for eye drops. While frequently used in ophthalmological prescriptions, it's a general term indicating a drop as a unit of measurement. A prescription might say "gtt ii OU qid" which would mean "two drops in both eyes four times a day." However, it could just as easily refer to ear drops or nasal drops, depending on the medication and accompanying instructions. The specific location of administration is usually clarified elsewhere in the prescription.
How many drops are in 1 ml?
The number of drops in one milliliter (ml) varies depending on the liquid's viscosity and the dropper used. There's no single definitive answer. Generally, it's estimated that there are approximately 20 drops in 1 ml, but this can range from 15 to 25, or even more. This variability highlights the importance of precise instructions in prescriptions and the need to use the prescribed dropper for consistent dosing.
What is the difference between gtts and gtt?
The difference is simply singular versus plural. "gtt" is the abbreviation for "gutta" (one drop), while "gtts" is the abbreviation for "guttae" (drops, plural). It's important to note that "gtt" is the more commonly used form even when referring to multiple drops. The numerical value before "gtt" clarifies the number of drops to be administered. For example, "2 gtt" is unambiguous, indicating two drops.
What are some common eye drop medications?
Many eye drop medications exist, treating various conditions. These include artificial tears for dry eyes, antibiotic drops for infections, steroid drops for inflammation, and glaucoma medications to lower intraocular pressure. The specific medication prescribed will depend entirely on your individual diagnosis. It's crucial to consult your ophthalmologist or healthcare provider for any eye-related concerns.
How should I properly administer eye drops?
Proper administration is crucial for effective treatment and to minimize the risk of contamination or side effects. Generally, you should:
- Wash your hands thoroughly.
- Tilt your head back.
- Pull down your lower eyelid to create a pocket.
- Hold the dropper above your eye and squeeze one drop into the pocket.
- Close your eyes gently and press gently on the inner corner of your eye (near your nose) for one to two minutes to help the medication stay in place.
- Wipe away any excess medication.
