⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Epistaxis, Nasal Ulceration, and Nasal Septal Perforation: Monitor patients periodically for signs of adverse effects on the nasal mucosa. Discontinue if ulcerations or perforations occur. Avoid use in patients with nasal disease other than allergic rhinitis (5.1) .
Avoid engaging in hazardous occupations requiring complete mental alertness and coordination, such as driving or operating machinery when taking olopatadine HCl (5.2) . Avoid concurrent use of alcohol or other central nervous system depressants with olopatadine HCl (5.2) .
5.1Local Nasal Effects Epistaxis and Nasal Ulceration In placebo-controlled clinical trials (vehicle nasal spray) of 2 weeks to 12 months duration, epistaxis and nasal ulcerations were reported [see Adverse Reactions (6.1) ] . Nasal Septal Perforation Three placebo-controlled long term (12 months) safety trials (vehicle nasal spray) were conducted. In the first safety trial, patients were treated with an investigational formulation of olopatadine HCl containing povidone (not the commercially marketed formulation) or a vehicle nasal spray containing povidone.
Nasal septal perforations were reported in one patient treated with the investigational formulation of olopatadine HCl and 2 patients treated with the vehicle nasal spray. In the second safety trial with olopatadine HCl, which does not contain povidone, there were no reports of nasal septal perforation. In the third safety trial, one patient exposed to the 3.7 pH vehicle nasal spray (containing no povidone) reported a nasal septal perforation [see Adverse Reactions (6.1) ] .
Before starting olopatadine HCl, conduct a nasal examination to ensure that patients are free of nasal disease other than allergic rhinitis. Perform nasal examinations periodically for signs of adverse effects on the nasal mucosa and consider stopping olopatadine HCl if patients develop nasal ulcerations.
5.2Somnolence and Impaired Mental Alertness In clinical trials, the occurrence of somnolence has been reported in some patients taking olopatadine HCl [see Adverse Reactions (6.1) ] . Patients should be cautioned against engaging in hazardous occupations requiring complete mental alertness and motor coordination, such as driving or operating machinery after administration of olopatadine HCl. Concurrent use of olopatadine HCl with alcohol or other central nervous system depressants should be avoided because additional reductions in alertness and additional impairment of central nervous system performance may occur.
🤒 Adverse Reactions ▾
6 ADVERSE REACTIONS The most clinically significant adverse reactions described in other sections of labeling include: Epistaxis, Nasal Ulceration, and Nasal Septal Perforation [see Warnings and Precautions (5.1) ] Somnolence and Impaired Mental Alertness [see Warnings and Precautions (5.2) ] The most common (> 1%) adverse reactions, included bitter taste, headache, epistaxis, pharyngolaryngeal pain, post-nasal drip, cough, and urinary tract infection in patients 12 years of age and older and epistaxis, headache, upper respiratory tract infection, bitter taste, pyrexia, and rash in patients 6 to 11 years of age (6.1) .

6.1Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The safety data described below reflect exposure to olopatadine HCl in 2,770 patients with seasonal or perennial allergic rhinitis in 10 controlled clinical trials of 2 weeks to 12 months duration. Olopatadine HCl is not indicated for use in patients with perennial allergic rhinitis.
The safety data from adults and adolescents are based upon 6 placebo-controlled clinical trials (3.7 pH vehicle nasal spray or 7.0 pH vehicle nasal spray) in which 1,834 patients with seasonal or perennial allergic rhinitis (652 males and 1,182 females) 12 years of age and older were treated with olopatadine HCl two sprays per nostril twice daily. There were 1,180 patients (olopatadine HCl, 587; vehicle nasal spray, 593) that participated in 3 efficacy and safety trials of 2 weeks duration. There were 2,840 patients (olopatadine HCl, 1,247; 3.7 pH vehicle nasal spray, 1,251; 7.0 pH vehicle nasal spray, 342) that participated in 3 long-term clinical trials of 1-year duration.
The racial distribution of adult and adolescent patients receiving olopatadine HCl was 77% white, 9% black, and 14% other. The incidence of discontinuation due to adverse reactions in these controlled clinical trials was comparable for olopatadine HCl and vehicle nasal spray. Overall, 4.7% of the 1,834 adult and adolescent patients across all 6 studies treated with olopatadine HCl, 3.5% of the 1,844 patients treated with 3.7 pH vehicle nasal spray discontinued due to adverse reactions, and 2.9% of the 342 patients treated with 7.0 pH vehicle nasal spray discontinued due to adverse reactions.
The safety data from pediatric patients 6 to 11 years of age are based upon 3 clinical trials in which 870 children with seasonal allergic rhinitis (376 females and 494 males) were treated with olopatadine HCl one or two sprays per nostril twice daily for 2 weeks. The racial distribution of pediatric patients receiving olopatadine HCl was 68.6% white, 16.6% black, and 14.8% other. The incidence of discontinuation due to adverse reactions in these controlled clinical trials was comparable for olopatadine HCl and vehicle nasal spray.
Overall, 1.4% of the 870 pediatric patients across all 3 studies treated with olopatadine HCl and 1.3% of the 872 pediatric patients treated with vehicle nasal spray discontinued due to adverse reactions. Adults and Adolescents 12 Years of Age and Older in Short-Term (2 week) Trials There were 1,180 patients 12 years of age and older (olopatadine HCl, 587; vehicle nasal spray, 593) that participated in 3 efficacy and safety trials of 2 weeks duration. Table 1 presents the most common adverse reactions (0.9% or greater in patients treated with olopatadine HCl) that occurred more frequently in patients treated with olopatadine HCl compared with vehicle nasal spray in the 3 clinical trials of 2 weeks duration.

🔄 Drug Interactions ▾
7 DRUG INTERACTIONS Formal drug-drug interaction studies were not conducted for olopatadine HCl. Drug interactions with inhibitors of liver enzymes are not anticipated because olopatadine is eliminated predominantly by renal excretion. Drug interactions involving P450 inhibition and plasma protein binding are also not expected [see Clinical Pharmacology (12.3) ] .
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS
8.1Pregnancy Risk Summary Published data from postmarketing experience with antihistamines, with similar mechanism of action to olopatadine HCl, have not identified a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. However, there are no published human data specific to olopatadine HCl. In animal reproductive studies, oral administration of olopatadine hydrochloride to pregnant rats and rabbits caused a decrease in the number of live fetuses at maternal doses approximately 110 and 1,460 times the maximum recommended human daily intranasal dose (MRHDID) on a mg/m 2 basis, respectively ( see Data ).
The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss or other adverse outcomes. In the U.S. general population, the background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4%, and 15% to 20%, respectively.
Data Animal Data In an oral embryo-fetal development study, pregnant rabbits were dosed throughout the period of organogenesis at doses up to 400 mg/kg/day. A decrease in the number of live fetuses was observed at 400 mg/kg/day (1,460 times the MRHDID, on a mg/m 2 basis). In an oral embryo-fetal development study, pregnant rats were dosed throughout the period of organogenesis at doses up to 600 mg/kg/day.
Maternal toxicity, producing death and reduced maternal body weight gain was observed at 600 mg/kg/day (approximately 1,100 times the MRHDID on a mg/m 2 basis). Olopatadine produced cleft palate at 60 mg/kg/day (approximately 110 times the MRHDID on a mg/m 2 basis) and decreased embryo-fetal viability and reduced fetal weight in rats at 600 mg/kg/day (approximately 1,100 times the MRHDID on a mg/m 2 basis). In peri-/postnatal toxicity studies, pregnant rats received oral doses of olopatadine up to 600 mg/kg/day during late gestation and throughout the lactation period.
Olopatadine produced decreased neonatal survival at 60 mg/kg/day (approximately 110 times the MRHDID on a mg/m 2 basis) and reduced body weight gain in pups at 4 mg/kg/day (approximately 7 times the MRHDID on a mg/m 2 basis). These effects appeared attributable to exposure of pups via the milk as demonstrated in a cross-fostered study in which pups of untreated dams cross-fostered to dams treated with 60 mg/kg/day olopatadine orally during the lactation period exhibited decreased body weight gain.
8.2Lactation Risk Summary There are no data on the presence of olopatadine in human milk, the effects on the breastfed infant, or the effects on milk production. Although orally administered olopatadine is present in rat milk, there is no information about nasally administered olopatadine. It is not known whether topical nasal administration could result in sufficient systemic absorption to produce detectable quantities in human breast milk.
The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for olopatadine HCl and any potential adverse effects on the breast fed infant from olopatadine HCl or from the underlying maternal condition.
8.4Pediatric Use The safety and effectiveness of olopatadine HCl for the relief of symptoms of seasonal allergic rhinitis have been established in pediatric patients aged 6 years and older. The safety and effectiveness of olopatadine HCl in pediatric patients 6 to 11 years of age are supported by 3 vehicle-controlled 2-week studies in 870 patients [see Adverse Reactions (6.1) ] . Doses studied included one and two sprays per nostril twice daily.
One of these studies evaluated the safety of olopatadine HCl at doses of one and two sprays per nostril twice daily in 1,188 patients, of which 298 patients were exposed to olopatadine HCl 1 spray, and 297 patients were exposed to vehicle 1 spray. In this study, the incidence of epistaxis with olopatad… [Excerpted — this section continues on DailyMed.]

🧒 Pediatric Use ▾
8.4Pediatric Use The safety and effectiveness of olopatadine HCl for the relief of symptoms of seasonal allergic rhinitis have been established in pediatric patients aged 6 years and older. The safety and effectiveness of olopatadine HCl in pediatric patients 6 to 11 years of age are supported by 3 vehicle-controlled 2-week studies in 870 patients [see Adverse Reactions (6.1) ] . Doses studied included one and two sprays per nostril twice daily.
One of these studies evaluated the safety of olopatadine HCl at doses of one and two sprays per nostril twice daily in 1,188 patients, of which 298 patients were exposed to olopatadine HCl 1 spray, and 297 patients were exposed to vehicle 1 spray. In this study, the incidence of epistaxis with olopatadine HCl use was 5.7% [see Adverse Reactions (6.1) , Clinical Studies (14) ] . The safety and effectiveness of olopatadine HCl in pediatric patients aged 12 years and older are supported by 3 randomized, double blind, parallel group, multicenter, placebo-controlled clinical trials of 2 weeks duration in adult and adolescent patients [see Clinical Studies (14) ] .
In these studies, the incidence of epistaxis with olopatadine HCl use in 587 patients was 3.2% [see Adverse Reactions (6.1) ] . The safety and effectiveness of olopatadine HCl have not been established in pediatric patients under 6 years of age. The safety of olopatadine HCl at a dose of one spray per nostril twice daily was evaluated in one 2-week vehicle-controlled study in 132 pediatric patients 2 to 5 years of age with allergic rhinitis.
In this trial, 66 patients were exposed to olopatadine HCl. The most common (greater than 1.0%) adverse reactions reported were diarrhea (9.1%), epistaxis (6.1%), rhinorrhea (4.5%), bitter taste (3.0%), and wheezing (3.0%). Diarrhea was reported more frequently (9.1%) in patients 2 to 5 years of age than 6 to 11 year old age group (< 1%).
🧓 Geriatric Use ▾
8.5Geriatric Use Clinical studies of olopatadine HCl did not include sufficient numbers of patients aged 65 years and older to determine whether they respond differently from younger patients. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, reflecting the greater frequency of decreased hepatic, renal, or cardiac function and of concomitant disease or other drug therapy.
🆘 Overdosage ▾
10 OVERDOSAGE Symptoms of antihistamine overdose may include drowsiness in both adults and children. Agitation and restlessness followed by drowsiness may also occur in children. There is no known specific antidote to olopatadine HCl.
Should overdose occur, symptomatic or supportive treatment is recommended, taking into account any concomitantly ingested medications. For additional information about overdose treatment, call a poison control center (1-800-222-1222).
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Olopatadine is a histamine H 1 receptor antagonist. The antihistaminic activity of olopatadine has been documented in isolated tissues, animal models, and humans.
12.2Pharmacodynamics Cardiac Electrophysiology In a placebo-controlled cardiovascular safety study, 32 healthy volunteers received 20 mg oral solution of olopatadine twice daily for 14 days (8-fold greater daily dose than the recommended daily nasal dose). The mean QTcF (QT corrected by Fridericia’s correction method for heart rate) change from baseline was -2.7 msec and -3.8 msec for olopatadine, and placebo, respectively. In this study, 8 subjects treated with olopatadine had a QTcF change from baseline of 30 to 60 msec, 1 subject had a QTcF change from baseline greater than 60 msec, and no subjects had QTcF values greater than 500 msec.
Eight subjects treated with placebo had a QTcF change from baseline of 30 to 60 msec, no subjects had a QTcF change from baseline greater than 60 msec, and no subjects had QTcF values greater than 500 msec. In a 12-month study in 429 perennial allergic rhinitis patients treated with olopatadine HCl two sprays per nostril twice daily, no evidence of any effect of olopatadine hydrochloride on QT prolongation was observed.
12.3Pharmacokinetics The pharmacokinetic properties of olopatadine were studied after administration by the nasal, oral, intravenous, and topical ocular routes. Olopatadine exhibited linear pharmacokinetics across the routes studied over a large dose range. Absorption Healthy Subjects: Olopatadine was absorbed with individual peak plasma concentrations observed between 30 minutes and 1 hour after twice daily intranasal administration of olopatadine HCl.
The mean (± SD) steady-state peak plasma concentration (C max ) of olopatadine was 16.0 ± 8.99 ng/mL. Systemic exposure as indexed by area under the curve (AUC 0-12 ) averaged 66.0 ± 26.8 ng·h/mL. The average absolute bioavailability of intranasal olopatadine is 57%.
The mean accumulation ratio following multiple intranasal administration of olopatadine HCl was about 1.3. Seasonal Allergic Rhinitis Patients: Systemic exposure of olopatadine in seasonal allergic rhinitis (SAR) patients after twice daily intranasal administration of olopatadine HCl was comparable to that observed in healthy subjects. Olopatadine was absorbed with peak plasma concentrations observed between 15 minutes and 2 hours.
The mean steady-state C max was 23.3 ± 6.2 ng/mL and AUC 0-12 averaged 78.0 ± 13.9 ng·h/mL. Distribution The protein binding of olopatadine was moderate at approximately 55% in human serum, and independent of drug concentration over the range of 0.1 to 1,000 ng/mL. Olopatadine was bound predominately to human serum albumin.
Elimination The plasma elimination half-life of olopatadine is 8 to 12 hours. Olopatadine is mainly eliminated through urinary excretion. Approximately 70% of a [ 14 C] olopatadine hydrochloride oral dose was recovered in urine with 17% in the feces.
Of the drug-related material recovered within the first 24 hours in the urine, 86% was unchanged olopatadine with the balance comprised of olopatadine N-oxide and N-desmethyl olopatadine. Metabolism Olopatadine is not extensively metabolized. Based on plasma metabolite profiles following oral administration of [ 14 C] olopatadine, at least six minor metabolites circulate in human plasma.
Olopatadine accounts for 77% of peak plasma total radioactivity and all metabolites amounted to < 6% combined. Two of these have been identified as the olopatadine N-oxide and N-desmethyl olopatadine. In in vitro studies with cDNA-expressed human cytochrome P450 isoenzymes (CYP) and flavin-containing monooxygenases (FMO), N-desmethyl olopatadine (Ml) formation was catalyzed mainly by CYP3A4, while olopatadine N-oxide (M3) was primarily catalyzed by FMO1 and FMO3.

🧬 Pharmacokinetics ▾
12.3Pharmacokinetics The pharmacokinetic properties of olopatadine were studied after administration by the nasal, oral, intravenous, and topical ocular routes. Olopatadine exhibited linear pharmacokinetics across the routes studied over a large dose range. Absorption Healthy Subjects: Olopatadine was absorbed with individual peak plasma concentrations observed between 30 minutes and 1 hour after twice daily intranasal administration of olopatadine HCl.
The mean (± SD) steady-state peak plasma concentration (C max ) of olopatadine was 16.0 ± 8.99 ng/mL. Systemic exposure as indexed by area under the curve (AUC 0-12 ) averaged 66.0 ± 26.8 ng·h/mL. The average absolute bioavailability of intranasal olopatadine is 57%.
The mean accumulation ratio following multiple intranasal administration of olopatadine HCl was about 1.3. Seasonal Allergic Rhinitis Patients: Systemic exposure of olopatadine in seasonal allergic rhinitis (SAR) patients after twice daily intranasal administration of olopatadine HCl was comparable to that observed in healthy subjects. Olopatadine was absorbed with peak plasma concentrations observed between 15 minutes and 2 hours.
The mean steady-state C max was 23.3 ± 6.2 ng/mL and AUC 0-12 averaged 78.0 ± 13.9 ng·h/mL. Distribution The protein binding of olopatadine was moderate at approximately 55% in human serum, and independent of drug concentration over the range of 0.1 to 1,000 ng/mL. Olopatadine was bound predominately to human serum albumin.
Elimination The plasma elimination half-life of olopatadine is 8 to 12 hours. Olopatadine is mainly eliminated through urinary excretion. Approximately 70% of a [ 14 C] olopatadine hydrochloride oral dose was recovered in urine with 17% in the feces.
Of the drug-related material recovered within the first 24 hours in the urine, 86% was unchanged olopatadine with the balance comprised of olopatadine N-oxide and N-desmethyl olopatadine. Metabolism Olopatadine is not extensively metabolized. Based on plasma metabolite profiles following oral administration of [ 14 C] olopatadine, at least six minor metabolites circulate in human plasma.
Olopatadine accounts for 77% of peak plasma total radioactivity and all metabolites amounted to < 6% combined. Two of these have been identified as the olopatadine N-oxide and N-desmethyl olopatadine. In in vitro studies with cDNA-expressed human cytochrome P450 isoenzymes (CYP) and flavin-containing monooxygenases (FMO), N-desmethyl olopatadine (Ml) formation was catalyzed mainly by CYP3A4, while olopatadine N-oxide (M3) was primarily catalyzed by FMO1 and FMO3.
Olopatadine at concentrations up to 33,900 ng/mL did not inhibit the in vitro metabolism of specific substrates for CYP1A2, CYP2C9, CYP2C19, CYP2D6, CYP2E1, and CYP3A4. The potential for olopatadine and its metabolites to act as inducers of CYP enzymes has not been evaluated. Specific Populations Patients with Hepatic Impairment No specific pharmacokinetic study examining the effect of hepatic impairment was conducted.
Since metabolism of olopatadine is a minor route of elimination, no adjustment of the dosing regimen of olopatadine HCl is warranted in patients with hepatic impairment. Patients with Renal Impairment The mean C max values for olopatadine following single nasal doses were not markedly different between healthy subjects (18.1 ng/mL) and patients with mild, moderate, and severe renal impairment (range 15.5 to 21.6 ng/mL). The mean plasma AUC 0-12 was 2-fold higher in patients with severe impairment (creatinine clearance < 30 mL/min/1.73 m 2 ).
In these patients, peak steady-state plasma concentrations of olopatadine are approximately 10-fold lower than those observed after higher 20 mg oral doses, twice daily, which were well-tolerated. These findings indicate that no adjustment of the dosing regimen of olopatadine HCl is warranted in patients with renal impairment. Male and Female Patients The mean systemic exposure (C max and AUC 0-12 ) in female SAR patients foll… [Excerpted — this section continues on DailyMed.]
🧬 Pharmacodynamics ▾
12.2Pharmacodynamics Cardiac Electrophysiology In a placebo-controlled cardiovascular safety study, 32 healthy volunteers received 20 mg oral solution of olopatadine twice daily for 14 days (8-fold greater daily dose than the recommended daily nasal dose). The mean QTcF (QT corrected by Fridericia’s correction method for heart rate) change from baseline was -2.7 msec and -3.8 msec for olopatadine, and placebo, respectively. In this study, 8 subjects treated with olopatadine had a QTcF change from baseline of 30 to 60 msec, 1 subject had a QTcF change from baseline greater than 60 msec, and no subjects had QTcF values greater than 500 msec.
Eight subjects treated with placebo had a QTcF change from baseline of 30 to 60 msec, no subjects had a QTcF change from baseline greater than 60 msec, and no subjects had QTcF values greater than 500 msec. In a 12-month study in 429 perennial allergic rhinitis patients treated with olopatadine HCl two sprays per nostril twice daily, no evidence of any effect of olopatadine hydrochloride on QT prolongation was observed.
🔬 Clinical Studies ▾
14 CLINICAL STUDIES Adult and Adolescent Patients 12 Years of Age and Older The efficacy and safety of olopatadine HCl were evaluated in 3 randomized, double blind, parallel group, multicenter, placebo-controlled clinical trials (vehicle nasal spray) of 2 weeks duration in adult and adolescent patients, 12 years of age and older with symptoms of seasonal allergic rhinitis. The 3 clinical trials were conducted in the United States and included 1,598 patients (556 males, and 1042 females) 12 years of age and older. In these 3 trials, 587 patients were treated with olopatadine HCl 0.6%, 418 patients were treated with olopatadine HCl 0.4%, and 593 patients were treated with vehicle nasal spray.
Assessment of efficacy was based on patient recording of 4 individual nasal symptoms (nasal congestion, rhinorrhea, itchy nose, and sneezing) on a 0 to 3 categorical severity scale (0 = absent, 1 = mild, 2 = moderate, 3 = severe) as reflective or instantaneous scores. Reflective scoring required patients to record symptom severity over the previous 12 hours; the instantaneous scoring required patients to record symptom severity at the time of recording. The primary efficacy endpoint was the difference from placebo in the percent change from baseline in the average of morning and evening reflective total nasal symptom score (rTNSS) averaged for the 2-week treatment period.
In all 3 trials, patients treated with olopatadine HCl, two sprays per nostril, twice-daily, exhibited statistically significantly greater decreases in rTNSS compared to vehicle nasal spray. Results for the rTNSS from 2 representative trials are shown in Table 3. Table 3: Mean Reflective Total Nasal Symptom Score (rTNSS) in Adult and Adolescent Patients With Seasonal Allergic Rhinitis Study No.

Itchy eyes and watery eyes were evaluated as secondary endpoints but eye redness was not evaluated. In 2 of the studies, patients treated with olopatadine HCl had significantly greater decreases in reflective symptom scores for itchy eyes and watery eyes, compared to vehicle nasal spray. In the 2-week seasonal allergy trials, onset of action was also evaluated by instantaneous TNSS assessments twice-daily after the first dose of study medication.
In these trials, onset of action was seen after 1 day of dosing. Onset of action was evaluated in 3 environmental exposure unit studies with single doses of olopatadine HCl. In these studies, patients with seasonal allergic rhinitis were exposed to high levels of pollen in the environmental exposure unit and then treated with either olopatadine HCl or vehicle nasal spray, two sprays in each nostril, after which they self-reported their allergy symptoms hourly as instantaneous scores for the subsequent 12 hours.
Olopatadine HCl 0.6% was found to have an onset of action of 30 minutes after dosing in the environmental exposure unit. Pediatric Patients 6 to 11 Years of Age There were 3 clinical trials of 2 weeks duration with olopatadine nasal spray in patients 6 to 11 years of age with seasonal allergic rhinitis. Efficacy of olopatadine HCl was evaluated in 2 of the 3 trials.
One of the 2 trials that showed efficacy was a randomized, double blind, parallel group, multicenter, placebo (vehicle nasal spray)-controlled clinical trial of 2 weeks duration, including 1,188 children ages 6 to < 12 years with seasonal allergic rhinitis. Assessment of efficacy was based on patient/caregiver recording of 4 individual nasal symptoms (nasal c… [Excerpted — this section continues on DailyMed.]
