Nepafenac
In StockNepafenac is a potent topical Non-Steroidal Anti-Inflammatory Drug (NSAID) used to treat pain and inflammation following cataract surgery and to reduce the risk of post-operative macular edema. It works by penetrating the cornea, where it is converted to the active Amfenac, which then inhibits prostaglandin synthesis. This API provides superior pain control and inflammation resolution in the anterior segment of the eye. Nepafenac is vital for post-operative ophthalmic care.
What Is Nepafenac?
Nepafenac is a prescription medication in the nonsteroidal anti-inflammatory drug (NSAID) class. It is used in the eye to reduce pain and swelling. It is not taken by mouth.
Approved uses and common prescribed uses
- Treating pain and inflammation after cataract surgery.
- The higher-strength version is also approved to help reduce the risk of swelling in the back of the eye (macular edema) after cataract surgery in people with diabetic retinopathy.
- Eye surgeons may also prescribe it for other short-term eye inflammation, as directed.
Available formulations and strengths
- Ophthalmic suspension (eye drops): Nepafenac 0.1%-5ml
- It is a cloudy liquid that must be shaken before use.
Availability varies by country and brand. Each strength has its own detailed page.
What Is the Recommended Dosage of Nepafenac?
Dosing depends on several factors:
- Condition: Pain and inflammation after cataract surgery and macular edema risk reduction use different strengths and schedules.
- Age: Nepafenac is approved for adults and, in some countries, for children aged 10 years and older. Use in younger children should only be directed by a pediatric eye specialist.
- Body weight: Weight is generally not used to set the dose of eye drops.
- Organ function: Dose changes are not usually needed for kidney or liver problems, but tell your specialist about these conditions.
Dosage form: Eye drop suspension in a multi-dose bottle.
The prescriber decides which strength to use, how many drops, in which eye, how often, and for how long. Treatment usually starts around the time of surgery and lasts for a set number of weeks. Shake the bottle well before each use. Do not use it longer than directed. Do not change your schedule without speaking with your specialist.
How Nepafenac Works
Nepafenac is a prodrug. This means it is converted inside the eye into its active form, called amfenac. Amfenac blocks enzymes called cyclooxygenase (COX-1 and COX-2). This reduces the production of prostaglandins, which are chemicals that cause pain, swelling, and inflammation.
Nepafenac relieves inflammation and pain during healing after eye surgery. It does not treat the cause of any eye disease and is meant for short-term use.
Is a Prescription Required to Buy Nepafenac Online?
Yes. Nepafenac is prescription-only. A licensed ophthalmologist (or another licensed eye care professional) must evaluate you and diagnose your condition first.
Safety when buying online
- Buy only from licensed, verified pharmacies that require a valid prescription.
- Avoid websites that sell prescription eye medicines without a prescription.
- Counterfeit, expired, or improperly stored eye drops can cause eye infection or vision harm. Do not use veterinary products.
- Check the packaging, label, and seal when it arrives. Ask a pharmacist if anything looks unusual.
Side Effects of Nepafenac
Common Side Effects
- Feeling that something is in the eye
- Eye pain or discomfort
- Brief stinging or burning when the drops are used
- Blurred vision or decreased vision
- Clouding of the lens capsule behind the eye lens (capsular opacity), which may occur after cataract surgery
- Eye redness or itching
- Headache
- Nausea
Serious Side Effects
These are uncommon but need prompt attention.
- Corneal problems: eye pain, a gritty feeling, light sensitivity, or vision changes. Rarely, NSAID eye drops can cause thinning of the cornea, ulcers, or a hole in the cornea, especially with long use or when combined with steroid eye drops.
- Delayed healing: the eye may heal more slowly after surgery
- Increased bleeding in the eye during or after surgery
- Raised eye pressure: eye pain, headache, or halos around lights
- Eye infection: pus, increasing pain, swelling, or worsening redness
- Signs of a severe allergic reaction: swelling of the face, lips, tongue, or throat; hives; trouble breathing; wheezing
Seek emergency medical care for trouble breathing, swelling of the face or throat, or sudden loss of vision. Contact your specialist promptly if eye pain gets worse, vision changes, or you notice signs of infection.
Drug Interactions
Few drug interactions are known with nepafenac eye drops, but some are important:
- Steroid eye drops: combined use with NSAID eye drops after surgery may raise the risk of slow healing and corneal problems in some people. Use only as directed
- Other NSAID eye drops: using two together is not usually recommended unless your specialist advises it
- Blood thinners and antiplatelet medicines, such as warfarin and aspirin: may increase the chance of eye bleeding
- Other eye drops: wait at least 5 minutes between different eye medicines
- Oral NSAIDs: tell your specialist if you take them, since nepafenac can be absorbed into the body in small amounts
OTC medicines, supplements, and herbal products, including aspirin, ibuprofen, and herbs that affect bleeding (such as ginkgo or fish oil in high amounts), may also interact. Give your licensed specialist and pharmacist a full list of everything you take, including eye drops, creams, vitamins, and supplements.
Safety & Important Considerations
- Cross-sensitivity: People who are allergic to aspirin or other NSAIDs may also react to nepafenac.
- Asthma: Some people with asthma are sensitive to aspirin and NSAIDs.
- Bleeding risk: Tell your specialist if you bruise or bleed easily or take blood thinners.
- Corneal health: Tell your specialist if you have corneal problems, dry eye, diabetes, rheumatoid arthritis, or have had repeat eye surgeries. These can raise the risk of corneal complications.
- Duration of use: Longer use than directed may raise the risk of corneal damage. Do not use more than your specialist advises.
- Pregnancy and breastfeeding: Human data are limited. NSAIDs are generally avoided late in pregnancy because they may harm the baby. It is not known whether nepafenac passes into breast milk. Discuss risks and benefits with your specialist before use.
- Children: Use only under the direction of a pediatric eye specialist.
- Older adults: No special dose change is usually needed.
- Contact lenses: Do not wear contact lenses while your eye is healing after surgery unless your specialist says it is safe. If you do wear them, remove them before use and wait at least 15 minutes before reinserting.
- Driving and machinery: Eye drops may briefly blur your vision. Avoid these activities until your vision is clear.
- Monitoring: Follow-up visits after eye surgery are important so your specialist can check healing and eye pressure.
- Hygiene: Do not touch the dropper tip to your eye or any surface. Contaminated eye drops can cause serious eye infections.
- Do not share your bottle with others.
