Diclax is a nonsteroidal anti-inflammatory drug (NSAID) used to treat pain and other symptoms of arthritis of the joints (eg, osteoarthritis), such as inflammation, swelling, stiffness, and joint pain. However, Diclax does not cure osteoarthritis and will help you only as long as you continue to use it.

Diclax topical 3% gel is also used to treat actinic keratosis, a skin problem that may become cancerous if not treated. The exact way that topical Diclax helps this condition is unknown.

Diclax topical solution is used to treat pain and swelling caused by osteoarthritis of the knees.

Diclax topical patch is used to treat acute pain caused by minor strains, sprains, and contusions (bruises).

Diclax is available only with your doctor's prescription.

General Dosing Instructions

Carefully consider the potential benefits and risks of Diclax and other treatment options before deciding to use Diclax. Use the lowest effective dosage for the shortest duration consistent with individual patient treatment goals.

The effectiveness of Diclax when taken with food has not been studied in clinical studies. Taking Diclax with food may cause a reduction in effectiveness compared to taking Diclax on an empty stomach.

Acute Pain

For management of mild to moderate acute pain, the dosage is 18 mg or 35 mg orally three times daily.

Osteoarthritis Pain

For management of osteoarthritis pain, the dosage is 35 mg orally three times daily.

Dosage Adjustments In Patients With Hepatic Impairment

Patients with hepatic disease may require reduced doses of Diclax compared to patients with normal hepatic function. As with other Diclax products, start treatment at the lowest dose. If efficacy is not achieved with the lowest dose, discontinue use.

Non-Interchangeability With Other Formulations Of Diclax

Diclax capsules are not interchangeable with other formulations of oral Diclax even if the milligram strength is the same. Diclax capsules contain Diclax free acid whereas other Diclax products contain a salt of Diclax, i.e., Diclax potassium or sodium. A 35 mg dose of Diclax is approximately equal to 37.6 mg of sodium Diclax or 39.5 mg of potassium Diclax. Therefore, do not substitute similar dosing strengths of other Diclax products without taking this into consideration.

The use of high dose Diclax (150 mg/day) for >4 weeks is contraindicated in patients with established cardiovascular disease (congestive heart failure, established ischemic heart disease, peripheral arterial disease) or uncontrolled hypertension.

Established Cardiovascular Disease or Significant Cardiovascular Risk Factors: The use of high dose Diclax (150mg/day) for >4 weeks is contraindicated in patients with established cardiovascular disease (congestive heart failure, established ischemic heart disease, peripheral arterial disease) or uncontrolled hypertension. If Diclax treatment is needed, patients with established cardiovascular disease, uncontrolled hypertension or significant cardiovascular risk factors (eg, hypertension, hyperlipidaemia, diabetes mellitus and smoking) should be treated only after careful consideration and at doses ≤100 mg daily if the treatment is for >4 weeks. As the cardiovascular risks of Diclax may increase with dose and duration of exposure, Diclax should always be prescribed at the lowest effective daily dose and for the shortest duration possible.

Renal Impairment: Diclax is contraindicated in patients with renal failure. No specific studies have been carried out in patients with renal impairment, therefore, no specific dose adjustment recommendations can be made. Caution is advised when administering Diclax to patients with mild to moderate renal impairment.

Hepatic Impairment: Diclax is contraindicated in patients with hepatic failure. No specific studies have been carried out in patients with hepatic impairment, therefore, no specific dose adjustment recommendations can be made. Caution is advised when administering Diclax to patients with mild to moderate hepatic impairment.

What other drugs will affect Diclax?

Aspirin: Concomitant administration of Diclax and aspirin is not recommended because Diclax is displaced from its binding sites during the concomitant administration of aspirin, resulting in lower plasma concentrations, peak plasma levels and AUC values.

Anticoagulants: While studies have not shown Diclax to interact with anticoagulants of the warfarin type, caution should be exercised, nonetheless, since interactions have been seen with other NSAIDs. Because prostaglandins play an important role in hemostasis and NSAIDs affect platelet function as well, concurrent therapy with all NSAIDs, including Diclax and warfarin, requires close monitoring of patients to be certain that no change in their anticoagulant dosage is required.

Digoxin, Methotrexate, Cyclosporine: Diclax, like other NSAIDs, may affect renal prostaglandins and increase the toxicity of certain drugs. Ingestion of Diclax may increase serum concentrations of digoxin and methotrexate and increase cyclosporine's nephrotoxicity. Patients who begin taking Diclax or who increase their Diclax dose or any other NSAID while taking digoxin, methotrexate or cyclosporine may develop toxicity characteristics for these drugs. They should be observed closely, particularly if renal function is impaired. In the case of digoxin, serum levels should be monitored.

Lithium: Diclax decreases lithium renal clearance and increases lithium plasma levels. In patients taking Diclax and lithium concomitantly, lithium toxicity may develop.

Oral Hypoglycemics:

Diuretics: Diclax and other NSAIDs can inhibit the activity of diuretics. Concomitant treatment with potassium-sparing diuretics may be associated with increased serum potassium levels.

Other Drugs: In small groups of patients (7-10/interaction study), the concomitant administration of azathioprine, gold, chloroquine, D-penicillamine, prednisolone, doxycycline or digitoxin did not significantly affect the peak levels and AUC values of Diclax. Phenobarbital toxicity has been reported to have occurred in a patient on chronic phenobarbital treatment following the initiation of Diclax therapy.

What are the possible side effects of Diclax?

Fluid Retention and Edema: Fluid retention and edema have been observed in some patients taking Diclax. Therefore, as with other NSAIDs, Diclax should be used with caution in patients with history of cardiac decompensation, hypertension or other conditions predisposing to fluid retention.

Hematological Effects: Anemia is sometimes seen in patients receiving Diclax or other NSAIDs. This may be due to fluid retention, GI blood loss or an incompletely described effect upon erythropoiesis.

Renal Effects: As a class, NSAIDs have been associated with renal papillary necrosis and other abnormal renal pathology in long-term administration to animals. In patients treated with Diclax, rare cases of interstitial nephritis and papillary necrosis have been reported. A second form of renal toxicity, generally associated with NSAIDs, is seen in patients with conditions leading to a reduction in renal blood flow or blood volume, where renal prostaglandins have a supported role in the maintenance of renal perfusion. In these patients, administration of an NSAID results in a dose-dependent decrease in prostaglandin synthesis and secondarily, in a reduction of renal blood flow, which may precipitate over the renal failure. Patients at greater risk of this reaction are those with impaired renal function, heart failure, liver dysfunction, those taking diuretics and the elderly.

Porphyria: The use of Diclax in patients with hepatic porphyria should be avoided.

Aseptic Meningitis: As with other NSAIDs, aseptic meningitis with fever and coma has been observed in rare occasions in patients on Diclax therapy. Although it is probably more likely to occur in patients with systemic lupus erythematosus and related connective tissue diseases, it has been reported in patients who do not have an underlying chronic disease. If signs or symptoms of meningitis develop in a patient on Diclax, the possibility of it being related to Diclax should be considered.

There may be pain and occasionally tissue damage at the site of injection when given IM.
