Document Summary
Explain that patient may feel a burning. Medication is given into conjunctival sac (avoid cornea due to increased pain sensation) Wait 5 mins between administering 2 medications. Hold dropper 1-2 cm above the conjunctival sac to avoid contamination. Hold lacrimal duct for 30-60 secs to decrease systemic absorption. Position patient in side-lying (sims) position with ear facing up. Straighten ear canal to allow medications to reach deeper external ear structures. Infants and children (>3 yrs): pull auricle down and back. Instill medications at room temperature to avoid vertigo. Hold dropper 1cm above ear canal to avoid contamination. Massage of tragus to help passage of ear drops. Inform patient to remain in position for 2-3 mins after instillation. Inform patient to remain in position for 10 mins after instillation. Offer patient frequent opportunities to maintain perineal hygiene. Insert for entire length of your finger (7. 5-10 cm) to ensure equal distribution of medication.
