Diclofenac

What is diclofenac?

Diclofenac is a nonsteroidal anti-inflammatory drug (NSAID). This medicine performs by decreasing substances in the body that cause pain and inflammation. Diclofenac is utilized to treat mild to moderate pain, or signs and/or symptoms of osteoarthritis or rheumatoid arthritis. Voltaren is also indicated for the therapy of ankylosing spondylitis. The Cataflam trademark of this medicine is also used to feast menstrual cramps.

Diclofenac powder (Cambia) is used to feast a migraine headache attack. Cambia will only feast on a headache that has already started. It will not control headaches or decrease the number of attacks.

About diclofenac

Diclofenac is a medicine that lowers swelling (inflammation) and pain. It helps to relieve aches and pains, as well as problems with joints, muscles, and bones. These include:

• rheumatoid arthritis and osteoarthritis
• sprains and strains in muscles and ligaments
• back pain
• toothache
• migraine
• gout
• Ankylosing Spondylitis – this causes inflammation of the spine and other parts of the body

Diclofenac comes as tablets and/or capsules, including slow-release tablets and capsules, and suppositories. These are available on prescription only. Diclofenac gel and plasters for joint pain are available to purchase from pharmacies. It can also be provided as an injection or as eyedrops. These are usually only given in hospitals. A high-strength diclofenac gel (including 3% diclofenac) is used to treat actinic keratoses (dry, scaly patches of skin generated by sun damage). This treatment is usually prompted after examination by a dermatologist and is not covered here.

Gastrointestinal

• Very familiar (10% or more): Nausea (up to 24%), constipation (up to 13%)
• Common (1% to 10%): Abdominal ache, diarrhea, dyspepsia, flatulence, gross bleeding or perforation, heartburn, gastric and/or duodenal ulcers, vomiting
• Rare (less than 0.1%): Colitis, eructation, pancreatitis
• Frequency not conveyed: Dry mouth, esophagitis, gastritis, glossitis, hematemesis, stomatitis

NSAIDs including this drug can also cause serious gastrointestinal (GI) events which can happen at any time, with or without warning. Of patients who develop a serious upper GI event, only about 20% were symptomatic. Upper Gastrointestinal ulcers, gross bleeding, or perforation occurred in approximately 1% of patients regaled with NSAIDs for 3 to 6 months and 2% to 4% of patients treated for 1 year. Patients with a previous history of peptic ulcer disease and/or Gastrointestinal bleeding had a more significant than 10-fold increased risk of developing a GI bleed than patients with neither of these risk elements.

Hepatic

Boundary elevations of 1 or more liver tests to more undersized than 3 times the upper limit of the normal (3 x ULN) or greater elevations in transaminases appeared in about 15% of patients treated with this drug. Heights greater than 3 x ULN of AST happened in roughly 2% (n=5700) of patients at some moment during therapy. In an open-labeled trial among patients acquiring NSAIDs, a higher incidence of transaminase elevations was observed in patients accepting diclofenac compared with other NSAIDs.

• Common (1% to 10%): Elevated liver enzymes
• Rare (smaller than 0.1%): Hepatitis, jaundice, liver disorder
• Very rare (shorter than 0.01%): Fulminant hepatitis, hepatic necrosis, hepatic failure
• Postmarketing reports: Drug-induced hepatotoxicity

Renal

• Common (1% to 10%): Abnormal renal function, enhanced serum creatinine
• Rare (more undersized than 0.1%): Nephrotic syndrome, interstitial nephritis, renal papillary necrosis, acute renal failure, urinary commonness, nocturia, proteinuria, and hematuria

Dermatologic

• Expected (1% to 10%): Pruritus, rashes
• Rare (more diminutive than 0.1%): Angioedema, toxic epidermal necrolysis, erythema multiforme, exfoliative dermatitis, Stevens-Johnson syndrome, urticaria
• Very rare (more undersized than 0.01%): Bullous eruptions, eczema, erythema, erythema multiforme, toxic epidermal necrolysis (Lyell’s syndrome), dermatitis exfoliative, losing of the hair, photosensitivity response

Hematologic

• Common (1% to 10%): Anemia, improved bleeding time
• Rare (smaller than 0.1%): Agranulocytosis, hemolytic anemia, aplastic anemia, lymphadenopathy, pancytopenia
• Very rare (smaller than 0.01%): Thrombocytopenia, leukopenia, positive Coombs’ test
• Frequency not conveyed: Ecchymosis, eosinophilia, melena, purpura, rectal bleeding

NSAIDs interfere with platelet accumulation and have been shown to prolong bleeding time in some patients. Unlike aspirin, the NSAID influence on platelet function is quantitatively more undersized, of shorter duration, and reversible.

Hypersensitivity

• Uncommon (0.1% to 1%): Urticaria, hives, angioedema, bronchospasm
• Rare (less than 0.1%): Anaphylactic reactions
• Very rare (smaller than 0.01%): Angioneurotic edema (including facial edema)

Nervous system

Clinical trials of several cyclooxygenases (COX)-2 selective and nonselective NSAIDs of up to 3 years duration have shown an increased risk of serious cardiovascular thrombotic events, myocardial infarction, and stroke, which can be fatal. All NSAIDs seem to have a similar risk. There is no consistent proof that concurrent use of aspirin mitigates this increased risk and may be associated with an improved risk of serious gastrointestinal events.

Pharmacoepidemiological data indicate an increased risk of arteriothrombotic circumstances associated with diclofenac use, particularly at a high dose and during long-term therapy. A meta-analysis of long-term therapy with diclofenac 150 mg/day, which corresponded with placebo usage of this drug resulted in approximately 3 additional major vascular events per 1000 players.

• Common (1% to 10%): Edema
• Uncommon (0.1% to 1%): Cardiac failure, chest pain
• Rare (less than 0.1%): Arrhythmia, hypotension, myocardial infarction, palpitations
