The response has been attributed toinhibition of renal prostaglandin synthesis. The mean minimum lithium concentration increased 15% and the renal clearance was decreased byapproximately 20%. This may indicate that they could enhance the toxicity of methotrexate. Therefore concomitant therapy with diclofenac may increase cyclosporines nephrotoxicity. Caution should be used when diclofenac is administered concomitantly with cyclosporine.

It contains the active ingredient, diclofenac sodium, in an opaque, white gel base. Diclofenacsodium is a white to slightly yellow crystalline powder. Diclofenac sodium is a benzeneacetic acidderivative. Themolecular weight is 318. It is notcompletely understood how reduced synthesis of these compounds results in therapeutic efficacy.

Postmarketing experience has shown severe hepatic reactions can occur at anytime during treatment with oral diclofenac. Cases of druginduced hepatotoxicity have been reported inthe first month, and in some cases, the first 2 months of therapy. Based on these experiences,transaminases should be monitored within 4 to 8 weeks after initiating treatment with oral diclofenac. If abnormal liver tests persist or worsen, if clinical signs and/or symptoms consistent with liver diseasedevelop, or if systemic manifestations non-prescription substitute for voltaren gel (e. To minimize the possibility that hepatic injury will become severe between transaminase measurements,physicians non-prescription substitute for voltaren gel inform patients of the warning signs and symptoms of hepatotoxicity (e.

Elderly patients are at greater risk for serious gastrointestinal events (5. Do not apply more voltaren gel drug 16 g daily to any one affected joint of the lower extremities.

Duration ofexposure ranged from 8 to 12 weeks for the placebocontrolled studies, and up to 12 months for theopenlabel safety trial. Table 1 lists the types of application site reactions reported. Application site reactions,including application site dermatitis, were the most frequent reason for treatment discontinuation. Adverse reactions thatled to the discontinuation of the study drug were experienced in 12% of patients. The most commonadverse reaction that led to discontinuation of the study was application site dermatitis, which wasexperienced by 6% of patients.

Do not apply more than 8 g daily to anysingle joint of the upper extremities. Total dose should not exceed 32 g per day, over all affected joints.

The entire footincludes the sole, top of the foot and the toes. Do not apply more than 16 g daily to any single joint ofthe lower extremities. The entirehand includes the palm, back of the hands, and the fingers.

Renal toxicity has also been seen in patients in whom renal prostaglandins have a compensatory role inthe maintenance of renal perfusion. Emergency help should be sought in caseswhere an anaphylactoid reaction occurs. Theseserious events may occur without warning. Patients should be informed about the signs and symptomsof serious skin manifestations, and the use of the drug should be discontinued at the first appearance ofskin rash or any other signs of hypersensitivity. Abrupt discontinuation of corticosteroids may lead to exacerbation of corticosteroidresponsiveillness.

However, even shortterm therapy is not without risk. Some of these reported cases resulted in fatalities or livertransplantation. Physicians should measure transaminases periodically in patients receiving longtermtherapy with oral diclofenac, because severe hepatotoxicity may develop without a prodrome ofdistinguishing symptoms. The optimum times for making the first and subsequent transaminasemeasurements are not known. In 42 of the 51 patients in all trialswho developed marked transaminase elevations, abnormal tests occurred during the first 2 months oftherapy with diclofenac.

For example, cover the skin above, below, inside and outside the knee cap. Remember that the foot includes the sole of your foot, the top of your foot and your toes.

In a dermal carcinogenicity study conducted in albino mice, daily topical applications of a diclofenacsodium gel product for two years at concentrations up to 0. In a photococarcinogenicity study conducted in hairless mice, topical application of a diclofenacsodium gel product at doses up to 0. Physician samples arepackaged in 20 g tubes. Patients should be instructed to minimize or avoid exposure of treated areas to natural or artificialsunlight.

Patients on prolonged corticosteroid therapy should have their therapy tapered slowlyif a decision is made to discontinue corticosteroids. Unlike aspirin, their effect on platelet function is quantitatively less, of shorter duration, and reversible. The use of aspirin in patients with aspirinsensitiveasthma has been associated with severe bronchospasm, which can be fatal. Patientsshould be advised that if eye contact occurs, they should immediately wash out the eye with water orsaline and consult a physician if irritation persists for more than an hour. Of these, 355 patients weretreated for osteoarthritis of 1 knee and 228 were treated for osteoarthritis of both knees.

There are no wellcontrolledstudies of diclofenac in pregnant women. Human and animal studies indicate that diclofenac crosses theplacenta. Gastrointestinal bleedingcan occur. Hypertension, acute renal failure, respiratory depression, and coma may occur. In the event of oral ingestion resulting in significant systemic side effects, it is recommended that thestomach be emptied by vomiting or lavage.

Forced diuresis may theoretically be beneficial because thedrug is excreted in the urine. The effect of dialysis or hemoperfusion in the elimination of diclofenac (99%proteinbound) remains unproven. In addition to supportive measures, the use of oral activated charcoalmay help to reduce the absorption of diclofenac. Supportive and symptomatic treatment should be given forcomplications such as renal failure, convulsions, gastrointestinal irritation, and respiratory depression. For additional information about overdose treatment, call a poison control center (18002221222).

Patients should be advised that if eye contact occurs, they shouldimmediately wash out the eye with water or saline and consult a physician if irritation persists formore than an hour.
