Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Nepafenac is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX) enzymes, primarily COX-2, reducing prostaglandin synthesis and thereby suppressing ocular inflammation and pain.
Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2), reducing prostaglandin synthesis, which mediates inflammation, pain, and fever. Pseudoephedrine is a sympathomimetic amine that acts as a decongestant by stimulating alpha-adrenergic receptors in the nasal mucosa, causing vasoconstriction.
Treatment of pain and inflammation associated with cataract surgery,Reduction of risk of macular edema following cataract surgery
Temporary relief of symptoms due to hay fever or other upper respiratory allergies: nasal congestion, sinus pressure, sneezing, runny nose, itching of nose or throat, and itchy, watery eyes due to allergies.,Temporary reduction of fever.,Relief of minor aches and pains associated with the common cold, headache, toothache, muscular aches, backache, menstrual cramps, and arthritis pain.
One drop of 0.1% ophthalmic suspension instilled into the affected eye(s) three times daily.
Ibuprofen 200 mg and pseudoephedrine HCl 30 mg per tablet. Usual adult dose: 1-2 tablets orally every 4-6 hours as needed, not to exceed 6 tablets in 24 hours.
The terminal elimination half-life of nepafenac is approximately 12.5 hours in plasma, while its active metabolite amfenac has a half-life of about 24 hours. This supports twice-daily dosing.
Ibuprofen: 2-4 hours; pseudoephedrine: 5-8 hours. Shorter half-life requires frequent dosing for sustained relief.
Nepafenac is metabolized via ocular tissues to amfenac, the active metabolite. Systemic metabolism primarily involves hepatic conjugation and oxidation.
Ibuprofen is primarily metabolized by cytochrome P450 (CYP) enzymes, mainly CYP2C9, to inactive metabolites (hydroxyibuprofen and carboxyibuprofen). Pseudoephedrine is partially metabolized in the liver by N-demethylation to an inactive metabolite.
Nepafenac is extensively metabolized, primarily via hydrolysis to amfenac. Renal excretion accounts for approximately 85% of the administered dose, with about 13% excreted as unchanged nepafenac and amfenac in urine. Fecal elimination is minimal.
Renal excretion of unchanged drug and metabolites; approximately 1% excreted unchanged (pseudoephedrine) and 15% (ibuprofen). Biliary/fecal elimination accounts for <5%.
Nepafenac is approximately 98% bound to plasma proteins, primarily albumin.
Ibuprofen: 99% bound to albumin; pseudoephedrine: negligible protein binding.
The apparent volume of distribution (Vd/F) is approximately 0.6 L/kg (range 0.5-0.7 L/kg), suggesting distribution into total body water and some tissue binding.
Ibuprofen: 0.1-0.2 L/kg; pseudoephedrine: 2.5-3 L/kg.
Ophthalmic: Systemic bioavailability after topical ocular administration is very low (approximately 0.1-1% of the dose), but sufficient for local ocular effects. Oral bioavailability is not clinically relevant as drug is only used ophthalmically.
Oral: ibuprofen 80-100%; pseudoephedrine 100%.
No dose adjustment required in renal impairment; systemic exposure is minimal due to topical administration.
For pseudoephedrine: Cr Cl <30 m L/min, reduce dose by 50% or administer every 12 hours. For ibuprofen: avoid use if Cr Cl <30 m L/min; if Cr Cl 30-59 m L/min, use lowest effective dose and monitor renal function.
No dose adjustment required in hepatic impairment; systemic exposure is minimal.
For ibuprofen: Child-Pugh class A and B: no adjustment necessary; Child-Pugh class C: avoid use. For pseudoephedrine: use with caution in severe hepatic impairment; no specific dose adjustment recommended, but monitor for adverse effects.
Safety and efficacy in pediatric patients have not been established; use is not recommended.
Not indicated for children under 12 years of age. For children 12 years and older: same as adult dose (1-2 tablets every 4-6 hours, max 6 tablets per day). Weight-based: not routinely used; safety and efficacy not established for <25 kg.
No specific dose adjustment; dosing is identical to standard adult dosing.
For ibuprofen: use lowest effective dose for shortest duration; monitor renal function and GI bleeding risk. For pseudoephedrine: initiate at lower doses (e.g., one tablet every 6 hours) due to increased sensitivity and risk of hypertension, urinary retention, and CNS effects.
No FDA black box warning.
Cardiovascular risk: NSAIDs may increase the risk of serious cardiovascular thrombotic events, myocardial infarction, and stroke, which can be fatal. Risk increases with duration of use and in patients with cardiovascular risk factors. Contraindicated for perioperative pain in coronary artery bypass graft (CABG) surgery. Gastrointestinal risk: NSAIDs increase the risk of serious gastrointestinal adverse events including bleeding, ulceration, and perforation of the stomach or intestines, which can be fatal. Elderly patients and those with prior peptic ulcer disease and/or GI bleeding are at greater risk.
Increased bleeding time due to antiplatelet effect,Delayed healing or corneal adverse events including keratitis and corneal perforation,Cross-sensitivity with aspirin or other NSAIDs,Use with caution in patients with bleeding diatheses or concurrent anticoagulants
Cardiovascular effects: may increase risk of heart attack or stroke; use lowest effective dose for shortest duration. Gastrointestinal effects: may cause GI ulceration, bleeding, perforation. Renal effects: avoid in advanced renal disease; monitor renal function. Hepatic effects: may cause liver enzyme elevation; discontinue if liver disease develops. Anaphylactic reactions: may occur in patients with or without prior NSAID sensitivity. Asthma: may cause bronchospasm. Hypertension: may worsen hypertension. Avoid in late pregnancy due to risk of premature closure of ductus arteriosus. Pseudoephedrine: may cause nervousness, dizziness, insomnia, hypertension, arrhythmias; use with caution in patients with cardiovascular disease, diabetes, glaucoma, prostatic hypertrophy, hyperthyroidism. Avoid in severe hypertension or coronary artery disease.
Hypersensitivity to nepafenac or any component of the formulation,History of asthma, urticaria, or allergic-type reactions to aspirin or other NSAIDs
Hypersensitivity to ibuprofen, pseudoephedrine, or any component of the formulation. History of asthma, urticaria, or allergic-type reaction after taking aspirin or other NSAIDs. In the setting of coronary artery bypass graft (CABG) surgery. Severe hypertension. Coronary artery disease. Concurrent use with or within 14 days of monoamine oxidase inhibitors (MAOIs) due to risk of hypertensive crisis. Pregnancy (third trimester).
No clinically significant food interactions have been identified with ophthalmic nevanac. Systemic absorption is minimal, so dietary restrictions are not required.
Take with food or milk to minimize GI upset. Avoid alcohol as it may increase risk of GI bleeding. No specific food-drug interactions.
Nepafenac is an NSAID. First trimester: limited human data, but NSAIDs as a class are associated with increased risk of spontaneous abortion and cardiac defects. Second trimester: generally considered lower risk for teratogenicity, but avoid if possible. Third trimester: increased risk of premature closure of the ductus arteriosus, oligohydramnios, and fetal renal impairment. Ophthalmic use results in minimal systemic absorption, but theoretical risks remain. Use only if clearly needed.
First trimester: Possible increased risk of cardiovascular malformations and gastroschisis with NSAID use. Second trimester: No specific malformation risk reported, but avoid prolonged use due to potential oligohydramnios. Third trimester: NSAIDs (including ibuprofen) are contraindicated due to risk of premature ductus arteriosus closure and oligohydramnios. Pseudoephedrine: Limited data; possible association with gastroschisis if used in first trimester; avoid due to vasoconstrictive effects.
No data on nepafenac in breast milk. Ophthalmic administration yields negligible systemic concentrations. M/P ratio not determined. Considered likely compatible with breastfeeding due to minimal absorption, but caution advised.
Ibuprofen: Excreted in low levels (M/P ratio ~0.006); considered compatible with breastfeeding. Pseudoephedrine: Excreted in breast milk (M/P ratio ~2.5-3.5); may reduce milk production and cause irritability in infants; use with caution.
No dose adjustments are typically required due to ophthalmic administration; systemic exposure is negligible. However, avoid use in third trimester unless potential benefit outweighs risk. No pharmacokinetic changes in pregnancy necessitate dose adjustment for topical ophthalmic formulation.
Ibuprofen: No specific dose adjustment recommended for pregnancy; however, avoid use in third trimester. Pseudoephedrine: No dose adjustment studied; use lowest effective dose for shortest duration. Neither drug is recommended for regular use during pregnancy.
Nevanac (nepafenac) is a nonsteroidal anti-inflammatory drug (NSAID) ophthalmic suspension indicated for pain and inflammation associated with cataract surgery. Its prodrug formulation enhances corneal penetration, with active metabolite amfenac inhibiting COX-1 and COX-2. Administer one drop three times daily starting 1 day prior to surgery, continuing on day of surgery and for 2 weeks postoperatively. Avoid concurrent use of other NSAIDs or corticosteroids to mitigate risk of corneal adverse events. Monitor for signs of corneal epithelial breakdown, especially in patients with compromised corneal innervation (e.g., diabetes, prior ocular surgery).
Combination of ibuprofen (NSAID) and pseudoephedrine (decongestant). Ibuprofen may increase blood pressure, counteracting pseudoephedrine's vasoconstriction; monitor in hypertensive patients. Avoid in patients with severe CAD, uncontrolled HTN, or within 2 weeks of MAOI use.
