Clinician-reviewed, head-to-head comparison of mechanism, dosing, pharmacokinetics, and safety profiles.
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.
Pseudoephedrine is a sympathomimetic amine that directly stimulates alpha-adrenergic receptors, causing vasoconstriction of nasal mucosa and sinus vessels. Chlorpheniramine is an alkylamine antihistamine that competitively antagonizes histamine H1 receptors, reducing allergic symptoms. Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, decreasing prostaglandin synthesis and reducing pain, fever, and inflammation.
Treatment of pain and inflammation associated with cataract surgery,Reduction of risk of macular edema following cataract surgery
Temporary relief of nasal congestion, sinus pressure, sneezing, runny nose, itchy/watery eyes, and headache due to colds or allergies,Fever reduction,Minor aches and pains
One drop of 0.1% ophthalmic suspension instilled into the affected eye(s) three times daily.
1-2 tablets (each tablet contains ibuprofen 200 mg and pseudoephedrine HCl 30 mg) orally every 4-6 hours as needed; maximum 6 tablets per day.
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.
2–4 hours (pseudoephedrine: 5–8 hours); clinical context: requires q4-6h dosing for pain/fever, q6-8h for congestion
Nepafenac is metabolized via ocular tissues to amfenac, the active metabolite. Systemic metabolism primarily involves hepatic conjugation and oxidation.
Ibuprofen: Primarily hepatic via CYP2C9; Pseudoephedrine: Hepatic via N-demethylation and oxidative metabolism; Chlorpheniramine: Hepatic via CYP2D6 and CYP3A4.
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 (90% as conjugates and metabolites; <10% unchanged); biliary/fecal (<5%)
Nepafenac is approximately 98% bound to plasma proteins, primarily albumin.
Ibuprofen: >99% (albumin); pseudoephedrine: <20% (albumin)
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: 2.5–3.5 L/kg (extensive tissue distribution)
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.
Ibuprofen: 80–100% oral; pseudoephedrine: >90% oral
No dose adjustment required in renal impairment; systemic exposure is minimal due to topical administration.
If GFR <30 m L/min: avoid use of ibuprofen component; pseudoephedrine dose interval may need to be increased (every 8-12 hours) due to reduced clearance.
No dose adjustment required in hepatic impairment; systemic exposure is minimal.
Child-Pugh Class A: no adjustment; Class B: use with caution, maximum ibuprofen dose 1200 mg/day; Class C: contraindicated due to risk of hepatotoxicity and renal impairment.
Safety and efficacy in pediatric patients have not been established; use is not recommended.
Not recommended for children under 12 years of age; for children ≥12 years: same as adult dose (200 mg ibuprofen/30 mg pseudoephedrine) every 4-6 hours, maximum 6 tablets per day.
No specific dose adjustment; dosing is identical to standard adult dosing.
Initiate at lowest effective dose (1 tablet every 6-8 hours); monitor renal function and blood pressure due to increased risk of GI bleeding, cardiovascular events, and pseudoephedrine-induced hypertension.
No FDA black box warning.
No FDA black box warning exists for this combination product. However, NSAIDs like ibuprofen carry a black box warning for increased risk of serious cardiovascular thrombotic events, myocardial infarction, and stroke, which can be fatal, especially with prolonged use or in patients with cardiovascular risk factors.
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 risk: NSAIDs increase risk of serious cardiovascular events. Gastrointestinal risk: NSAIDs can cause bleeding, ulceration, and perforation. Hypertension: Pseudoephedrine may elevate blood pressure. Avoid use with MAOIs or within 14 days of stopping. Caution in hyperthyroidism, diabetes, glaucoma, prostatic hypertrophy, and renal impairment.
Hypersensitivity to nepafenac or any component of the formulation,History of asthma, urticaria, or allergic-type reactions to aspirin or other NSAIDs
Hypersensitivity to any component; Concurrent MAOI therapy; Severe hypertension or coronary artery disease; Active peptic ulcer disease; History of aspirin/NSAID-induced asthma; Pregnancy (especially third trimester); Children under 12 years (per product labeling).
No clinically significant food interactions have been identified with ophthalmic nevanac. Systemic absorption is minimal, so dietary restrictions are not required.
Avoid alcohol due to increased risk of GI bleeding and liver toxicity. No known food interactions with chlorpheniramine or pseudoephedrine. Taking with food may reduce gastric irritation from ibuprofen.
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: NSAIDs are associated with increased risk of miscarriage and congenital malformations (cardiac defects, gastroschisis). Third trimester: Risk of premature closure of ductus arteriosus, oligohydramnios, and necrotizing enterocolitis. Avoid use after 30 weeks gestation.
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 and pseudoephedrine are excreted into breast milk. Ibuprofen has low milk/plasma ratio (0.01-0.07) and is generally considered compatible. Pseudoephedrine may reduce milk production and cause irritability in infants. Use with caution, especially in preterm infants.
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.
No specific dose adjustments recommended for pregnancy; however, use the lowest effective dose for the shortest duration. Avoid in third trimester. Pseudoephedrine dose remains standard; caution in hypertensive disorders.
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).
Advil Allergy Sinus contains ibuprofen (NSAID), chlorpheniramine (first-generation antihistamine), and pseudoephedrine (decongestant). Avoid in patients with aspirin/NSAID allergy, severe hypertension, coronary artery disease, or MAOI use. Caution in elderly due to anticholinergic effects. Pseudoephedrine may cause insomnia and anxiety; avoid evening dosing.
