What is Dexafree and How Does it Work?
Dexafree is an eye drop formulation containing the corticosteroid dexamethasone, an anti-inflammatory medication. It is primarily prescribed to treat inflammatory conditions of the eye by reducing swelling, pain, heat, and redness. The medication works by suppressing the body's inflammatory response.
Dexafree is particularly notable because it comes in single-dose, preservative-free containers. This makes it suitable for individuals who may have allergies or sensitivities to preservatives found in multi-dose eye drop bottles. It is used for various conditions, including inflammation following eye surgery, injuries, and certain types of conjunctivitis.
Preparing to Use Dexafree
Before you begin the application process, proper preparation is key to ensuring sterility and effectiveness. Following these steps helps prevent the introduction of bacteria into the eye and ensures you get the full benefit of the medication.
Step-by-Step Preparatory Instructions
- Wash your hands thoroughly: Use soap and water to clean your hands completely before handling the single-dose container.
- Remove contact lenses: If you wear contact lenses, they must be removed before using Dexafree, as the medication can affect them and cause blurred vision. You should wait at least 15 minutes after application before re-inserting them.
- Inspect the container: Check the single-dose container for any damage. Do not use if it appears compromised.
- Gather materials: Prepare a clean tissue to wipe away any excess liquid after application.
- Sit or lie down comfortably: Find a steady position to avoid shaking or making a mistake during application.
The Proper Technique for Applying Dexafree
Correct application is critical for the medicine to work effectively and to prevent contamination.
Application Steps
- Open the single-dose unit: Twist off the cap of the container. Discard the container after immediate use.
- Tilt your head back: Look upwards toward the ceiling.
- Create a pocket: Use your index finger to gently pull down your lower eyelid, forming a small pouch.
- Position the dropper: Hold the container upside down with your other hand, positioning the tip as close to your eye as possible without touching it. This prevents contamination of the dropper tip.
- Instill the drop: Gently squeeze the container to release one drop into the pocket formed by your lower eyelid. It is normal if a small amount of liquid spills out; your eye can only hold a certain volume.
- Release your eyelid: Slowly let go of the lower eyelid.
- Close your eye gently: Close your eye for 1 to 2 minutes. Do not blink or squeeze your eyelids forcefully.
- Apply pressure to your tear duct: Using a finger, apply gentle pressure to the inner corner of your eye, near the nose. This helps prevent the medicine from draining out and maximizes absorption into the eye.
- Wipe away excess: Use the clean tissue to wipe any extra drops from your face.
