How does this medication work? What will it do for me?
Nepafenac belongs to the class of medications known as nonsteroidal anti-inflammatory drugs (NSAIDs). It works by reducing pain, swelling, and inflammation. Nepafenac eye drops are used to reduce eye pain and inflammation before and after cataract surgery.
This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of this medication may not be used for all of the conditions discussed here.
Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are using this medication, speak to your doctor. Do not stop using this medication without consulting your doctor.
Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to use this medication if their doctor has not prescribed it.
What form(s) does this medication come in?
Each mL of ophthalmic suspension contains nepafenac 1 mg (0.1%). Nonmedicinal ingredients: mannitol, carbomer 974P, sodium chloride, tyloxapol, edetate disodium, sodium hydroxide and/or hydrochloric acid (to adjust pH), purified water, and the preservative benzalkonium chloride 0.005%.
How should I use this medication?
The recommended dose of nepafenac eye drops is 1 drop in the affected eye 3 times daily, starting the day before cataract surgery, continued on the day of surgery, and for as long as your doctor asks you to keep using them. This may be for as long as 2 weeks after the surgery.
Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are using the medication without consulting your doctor.
To use eye drops properly:
- Wash your hands before using the eye drops.
- Shake the container well before use to ensure the medication is evenly mixed throughout the bottle.
- Remove the cap and place it in a clean location. To avoid possible contamination, keep the tip of the container away from contact with any surface.
- Tilt your head back and look towards the ceiling.
- With your index finger, gently pull the lower eyelid down and away from the eye to form a pouch.
- Apply one drop into the pouch but do not allow the tip of the container to touch the eye or areas around the eye.
- Gently apply pressure to the inner corner of the eye (at the bridge of the nose) for about 30 seconds. (This is called nasolacrimal occlusion.) This prevents the medication from dripping down through the tear duct and entering the bloodstream, which could cause you to experience some side effects.
- Repeat with the other eye, if prescribed by your physician.
- Wash your hands again to remove any medication.
If you are using more than one topical eye medication (eye drops or ointment), wait at least 5 minutes before putting another medication in the eye. Contact lenses should not be worn during treatment with this medication.
Ask your doctor or pharmacist to show you the correct method of applying eye drops. It is very important to avoid touching the dropper tip to any surface, skin, or your eye. This contamination can result in a bacterial infection. Report any signs of an eye infection (e.g., redness, irritation, pain) to your doctor immediately.
It is important that this medication be used exactly as prescribed by your doctor. If you miss a dose, instill it as soon as possible and continue with your regular schedule. If it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not instill a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.
Store this medication at room temperature, protect it from light and moisture and keep it out of the reach of children.
Safely discard any medication remaining in the dropper bottle after you have used the medication for the full length of time recommended by your doctor. Discard any remaining medication 28 days after opening the bottle.
Do not dispose of medications in wastewater (e.g. down the sink or in the toilet) or in household garbage. Ask your pharmacist how to dispose of medications that are no longer needed or have expired.
