Clinical Drug Information
Indications & Usage
1 INDICATIONS AND USAGE Diclofenac sodium topical solution, USP is indicated for the treatment of signs and symptoms of osteoarthritis of the knee(s) (1). Diclofenac sodium topical solution is a nonsteroidal anti-inflammatory drug indicated for the treatment of signs and symptoms of osteoarthritis of the knee(s). ( 1 )
Dosage & Administration
2 DOSAGE AND ADMINISTRATION Use the lowest effective dosage for the shortest duration consistent with individual patient treatment goals. The recommended dose is 40 drops on each painful knee, 4 times a day. ( 2 ) Apply diclofenac sodium topical solution to clean, dry skin. ( 2.1 ) Dispense diclofenac sodium topical solution 10 drops at a time either directly onto the knee or first into the hand and then onto the knee. Spread diclofenac sodium topical solution evenly around front, back and sides of the knee. Repeat this procedure until 40 drops have been applied and the knee is completely covered with solution. ( 2.1 ) Wash hands completely after administering the product. Wait until the area is completely dry before covering with clothing or applying sunscreen, insect repellent, cosmetics, topical medications, or other substances. Until the treated knee(s) is completely dry, avoid skin-to-skin contact between other people and the treated knee(s). ( 2.2 ) Do not get diclofenac sodium topical solution in your eyes, nose or mouth. 2.1 General Dosing Instructions Use the lowest effective dosage for the shortest duration consistent with individual patient treatment goals [ see Warning and Precautions (5.2) ]. For the relief of the signs and symptoms of osteoarthritis of the knee(s), the recommended dose is 40 drops per knee, 4 times a day. Apply diclofenac sodium topical solution to clean, dry skin. To avoid spillage, dispense diclofenac sodium topical solution 10 drops at a time either directly onto the knee or first into the hand and then onto the knee. Spread diclofenac sodium topical solution evenly around front, back and sides of the knee. Repeat this procedure until 40 drops have been applied and the knee is completely covered with solution. To treat the other knee, if symptomatic, repeat the procedure. Application of diclofenac sodium topical solution in an amount exceeding or less than the recommended dose has not been studied and is therefore not recommended. 2.2 Special Precautions Avoid showering/bathing for at least 30 minutes after the application of diclofenac sodium topical solution to the treated knee. Wash and dry hands after use. Do not apply diclofenac sodium topical Solution USP, to open wounds. Avoid contact of diclofenac sodium topical solution with eyes and mucous membranes. Do not apply external heat and/or occlusive dressings to treated knees. Avoid wearing clothing over the diclofenac sodium topical solution treated knee(s) until the treated knee is dry. Protect the treated knee(s) from natural or artificial sunlight. Wait until the treated area is dry before applying sunscreen, insect repellant, lotion, moisturizer, cosmetics, or other topical medication to the same knee you have just treated with diclofenac sodium topical solution. Until the treated knee(s) is completely dry, avoid skin-to-skin contact between other people and the treated knee(s). Do not use combination therapy with diclofenac sodium and an oral NSAID unless the benefit outweighs the risk and conduct periodic laboratory evaluations.
Adverse Reactions
6 ADVERSE REACTIONS The following adverse reactions are discussed in greater detail in other sections of the labeling: Cardiovascular Thrombotic Events [ see Warnings and Precautions (5.1) ] GI Bleeding, Ulceration and Perforation [ see Warnings and Precautions (5.2) ] Hepatotoxicity [ see Warnings and Precautions (5.3) ] Hypertension [ see Warnings and Precautions (5.4) ] Heart Failure and Edema [ see Warnings and Precautions (5.5) ] Renal Toxicity and Hyperkalemia [ see Warnings and Precautions (5.6) ] Anaphylactic Reactions [ see Warnings and Precautions (5.7) ] Serious Skin Reactions [ see Warnings and Precautions (5.9) ] Hematologic Toxicity [ see Warnings and Precautions (5.12) ] The most common adverse reactions with diclofenac sodium topical solution are application site reactions. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Taro Pharmaceuticals U.S.A., Inc. at 1-866-923-4914 or the FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical 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 data described below reflect exposure to diclofenac sodium topical solution of 911 patients treated between 4 and 12 weeks (mean duration of 49 days) in seven Phase 3 controlled trials, as well as exposure of 793 patients treated in an open-label study, including 463 patients treated for at least 6 months, and 144 patients treated for at least 12 months. The population mean age was approximately 60 years, 89% of patients were Caucasians, 64% were females, and all patients had primary osteoarthritis. The most common adverse events with diclofenac sodium topical solution were application site skin reactions. These events were the most common reason for withdrawing from the studies. Application Site Reactions In controlled trials, the most common treatment-related adverse events in patients receiving diclofenac sodium topical solution were application site skin reactions. Application site reactions were characterized by one or more of the following: dryness, erythema, induration, vesicles, paresthesia, pruritus, vasodilation, acne, and urticaria. The most frequent of these reactions were dry skin (32%), contact dermatitis characterized by skin erythema and induration (9%), contact dermatitis with vesicles (2%) and pruritus (4%). In one controlled trial, a higher rate of contact dermatitis with vesicles (4%) was observed after treatment of 152 subjects with the combination of diclofenac sodium topical solution and oral diclofenac. In the open label uncontrolled long-term safety study, contact dermatitis occurred in 13% and contact dermatitis with vesicles in 10% of patients, generally within the first 6 months of exposure, leading to a withdrawal rate for an application site event of 14%. Adverse Events Common to the NSAID Class In controlled trials, subjects treated with diclofenac sodium topical solution experienced some adverse events associated with the NSAID class more frequently than subjects using placebo (constipation, diarrhea, dyspepsia, nausea, flatulence, abdominal pain, edema; see Table 1 ). The combination of diclofenac sodium topical solution and oral diclofenac, compared to oral diclofenac alone, resulted in a higher rate of rectal hemorrhage (3% vs. less than 1%), and more frequent abnormal creatinine (12% vs. 7%), urea (20% vs. 12%), and hemoglobin (13% vs. 9%), but no difference in elevation of liver transaminases. Table 1 lists all adverse reactions occurring in ≥1% of patients receiving diclofenac sodium topical solution, where the rate in the diclofenac sodium topical solution group exceeded placebo, from seven controlled studies conducted in patients with osteoarthritis. Since these trials were of different durations, these percentages do not capture cumulative rates of occurrence.

Information for Patients
17 PATIENT COUNSELING INFORMATION Advise the patient to read the FDA-approved patient labeling (Medication Guide) and Instructions for Use that accompanies each prescription dispensed. Inform patients, families, or their caregivers of the following information before initiating therapy with diclofenac sodium and periodically during the course of ongoing therapy. Cardiovascular Thrombotic Events Advise patients to be alert for the symptoms of cardiovascular thrombotic events, including chest pain, shortness of breath, weakness, or slurring of speech, and to report any of these symptoms to their health care provider immediately [ see Warnings and Precautions (5.1) ]. Gastrointestinal Bleeding, Ulceration, and Perforation Advise patients to report symptoms of ulcerations and bleeding, including epigastric pain, dyspepsia, melena, and hematemesis to their health care provider. In the setting of concomitant use of low-dose aspirin for cardiac prophylaxis, inform patients of the increased risk for and the signs and symptoms of GI bleeding [ see Warnings and Precautions (5.2) ]. Hepatotoxicity Inform patients of the warning signs and symptoms of hepatotoxicity (e.g., nausea, fatigue, lethargy, pruritus, diarrhea, jaundice, right upper quadrant tenderness, and "flu-like" symptoms). If these occur, instruct patients to stop diclofenac sodium and seek immediate medical therapy [ see Warnings and Precautions (5.3) ]. Heart Failure and Edema Advise patients to be alert for the symptoms of congestive heart failure including shortness of breath, unexplained weight gain, or edema and to contact their healthcare provider if such symptoms occur [ see Warnings and Precautions (5.5) ]. Anaphylactic Reactions Inform patients of the signs of an anaphylactic reaction (e.g., difficulty breathing, swelling of the face or throat). Instruct patients to seek immediate emergency help if these occur [ see Contraindications (4) and Warnings and Precautions (5.7) ]. Serious Skin Reactions, including DRESS Advise patients to stop taking diclofenac sodium immediately if they develop any type of rash or fever and to contact their healthcare provider as soon as possible [ see Warnings and Precautions (5.10 , 5.9) ]. Female Fertility Advise females of reproductive potential who desire pregnancy that NSAIDs, including diclofenac sodium, may be associated with a reversible delay in ovulation [ see Use in Specific Populations (8.3) ]. Fetal Toxicity Inform pregnant women to avoid use of diclofenac sodium and other NSAIDs starting at 30 weeks gestation because of the risk of the premature closing of the fetal ductus arteriosus. If treatment with diclofenac sodium is needed for a pregnant woman between about 20 to 30 weeks gestation, advise her that she may need to be monitored for oligohydramnios, if treatment continues for longer than 48 hours [ see Warnings and Precautions (5.11) and Use in Specific Populations (8.1) ]. Avoid Concomitant Use of NSAIDs Inform patients that the concomitant use of diclofenac sodium with other NSAIDs or salicylates (e.g., diflunisal, salsalate) is not recommended due to the increased risk of gastrointestinal toxicity, and little or no increase in efficacy [ see Warnings and Precautions (5.2) and Drug Interactions (7) ]. Alert patients that NSAIDs may be present in "over-the-counter" medications for treatment of colds, fever, or insomnia. Use of NSAIDs and Low-Dose Aspirin Inform patients not to use low-dose aspirin concomitantly with diclofenac sodium until they talk to their healthcare provider [ see Drug Interactions (7) ]. Eye Exposure Instruct patients to avoid contact of diclofenac sodium with the eyes and mucosa. Advise patients that if eye contact occurs, immediately wash out the eye with water or saline and consult a physician if irritation persists for more than an hour. Prevention of Secondary Exposure Instruct patients to avoid skin-to-skin contact between other people and the knee(s) to which diclofenac sodium was applied until the knee(s) is completely dry. Application Site Reactions Diclofenac sodium can cause a localized skin reaction at the application site. Advise patients to contact their physicians as soon as possible if they develop any type of localized application site rash. Special Application Instructions Instruct patients not to apply diclofenac sodium to open skin wounds, infections, inflammations, or exfoliative dermatitis, as it may affect absorption and reduce tolerability of the drug. Instruct patients to wait until the area treated with diclofenac sodium is completely dry before applying sunscreen, insect repellant, lotion, moisturizer, cosmetics, or other topical medication. Instruct patients to minimize or avoid exposure of treated knee(s) to natural or artificial sunlight.
