What are the uses of this medicine?

Diclofenac potassium (Cataflam) is used:

• For treatment of primary dysmenorrhea
• For relief of mild to moderate pain
• For relief of the signs and symptoms of osteoarthritis
• For relief of the signs and symptoms of rheumatoid arthritis

How does this medicine work?

• Diclofenac has analgesic, anti-inflammatory, and antipyretic properties.
• The mechanism of action of CATAFLAM, like that of other NSAIDs, is not completely understood but involves inhibition of cyclooxygenase (COX-1 and COX-2).
• Diclofenac is a potent inhibitor of prostaglandin synthesis in vitro.
• Prostaglandins are mediators of inflammation.
• Because diclofenac is an inhibitor of prostaglandin synthesis, its mode of action may be due to a decrease of prostaglandins in peripheral tissues.

Who Should Not Use this medicine ?

This medicine cannot be used in patients with:

• Known hypersensitivity (e.g., anaphylactic reactions and serious skin reactions) to diclofenac or any components of the drug product.
• History of asthma, urticaria, or allergic type reactions after taking aspirin or other NSAIDs.

• new or worse high blood pressure
• heart failure
• liver problems including liver failure
• kidney problems including kidney failure
• low red blood cells (anemia)

What special precautions should I follow?

• CATAFLAM (diclofenac potassium tablets, USP) cannot be expected to substitute for corticosteroids or to treat corticosteroid insufficiency. Abrupt discontinuation of corticosteroids may lead to disease exacerbation.
• Patients on prolonged corticosteroid therapy should have their therapy tapered slowly if a decision is made to discontinue corticosteroids and the patient should be observed closely for any evidence of adverse effects.
• 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 healthcare provider immediately.
• Advise patients to report symptoms of ulcerations and bleeding, including epigastric pain, dyspepsia, melena, and hematemesis to their healthcare provider. In the setting of concomitant use of low-dose aspirin for cardiac prophylaxis, inform patients of the increased risk for the signs and symptoms of GI bleeding.
• 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).
• 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.
• 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.
• Advise patients to stop taking CATAFLAM immediately if they develop any type of rash or fever and to contact their healthcare provider as soon as possible.
• Advise females of reproductive potential who desire pregnancy that NSAIDs, including VOLTAREN®, may be associated with a reversible delay in ovulation.
• Inform pregnant women to avoid use of CATAFLAM 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 potassium tablets 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.
• Inform patients that the concomitant use of CATAFLAM with other NSAIDs or salicylates (e.g., diflunisal, salsalate) is not recommended.
• Inform patients not to use low-dose aspirin concomitantly with CATAFLAM until they talk to their healthcare provider.
• The pharmacological activity of CATAFLAM in reducing fever and inflammation, and possibly fever, may diminish the utility of these diagnostic signs in detecting infections.
• Based on available data, diclofenac may be present in human milk.

What to do in case of emergency/overdose?

Symptoms of overdosage may include:

• lethargy
• drowsiness
• nausea
• vomiting
• epigastric pain
• Gastrointestinal
• Hypertension
• acute renal failure
• respiratory depression
• coma

Management of overdosage:

• In case of overdose, call the poison control helpline of your country. In the United States, call 1-800-222-1222.

• Overdose related information is also available online at poisonhelp.org/help.
• In the event that the victim has collapsed, had a seizure, has trouble breathing, or can't be awakened, immediately call emergency services. In the United States, call 911.
• Manage patients with symptomatic and supportive care following an NSAID overdosage.
• There are no specific antidotes.
• Consider emesis and/or activated charcoal (60 to 100 grams in adults, 1 to 2 grams per kg of body weight in pediatric patients) and/or osmotic cathartic in symptomatic patients seen within four hours of ingestion in patients with a large overdose (5 to 10 times the recommended dosage).
• Forced diuresis, alkalinization of urine, hemodialysis, or hemoperfusion may not be useful due to high protein binding.

Can this medicine be used in pregnancy?

• Use of NSAIDs, including CATAFLAM, can cause premature closure of the fetal ductus arteriosus and fetal renal dysfunction leading to oligohydramnios and, in some cases, neonatal renal impairment.
• Because of these risks, limit dose and duration of CATAFLAM use between about 20 and 30 weeks of gestation and avoid CATAFLAM use at about 30 weeks of gestation and later in pregnancy.

Can this medicine be used in children?

• Safety and effectiveness in pediatric patients have not been established.
