- 2 weeks for muscle and joint injuries (e.g. sprains, strains, bruises) or tendonitis.
- 3 weeks for arthritis pain without consulting a doctor or pharmacist.
Use no more than is required for shortest period of time needed. If the pain and swelling do not improve within 7 days, or if they get worsen, consult the doctor or pharmacist.
Contra-indications
Do not take if you:
- are allergic to diclofenac or other non-steroidal anti- inflammatory medicines (ibuprofen or aspirin) used to treat pain, fever or inflammation or any of the other ingredients contained in this medicine. If you are not sure, ask your doctor or pharmacist. (Symptoms of an allergic reaction to these medicines may include: wheezing or shortness of breath (asthma); skin rash with blisters or hives; swelling of the face or tongue; runny nose.)
- If you are in the last 3 months of pregnancy
Warnings and Precautions
Do not apply to skin with conditions such as cuts, open wounds, or on skin that has a rash or eczema. Discontinue the treatment if a skin rash develops after applying the product.
Do not use more product than directed or for a longer period of time than directed, unless told by your doctor or pharmacist.
Do not use in the mouth. Do not swallow. Wash your hands after use. Be careful not to get this medicine in your eyes. If this happens, rinse your eyes well with clean water. See your doctor or pharmacist if any discomfort persists.
A brace or wrap commonly used for injuries like sprains can be used but do not use under airtight (plastic) bandages.
Voltaren Emulgel contains propylene glycol esters, which may cause mild, localised skin irritation in some people.
Keep out of the sight and reach of children.
Patients should be instructed to be cautious when smoking or near naked flames due to risk of severe burns. Voltaren contains paraffin which is potentially flammable when it builds up on fabric (clothing, bedding, dressings etc.). Washing clothing and bedding may reduce product build up but not totally remove it.
Adverse effects
When using this product, you may experience:
- Skin rash with or without blisters; hives; wheezing, shortness of breath or feeling of tightness in the chest (asthma); swelling of the face, lips, tongue or throat; itching or reddening of the skin.
- The skin may be more sensitive to sunlight (sun or tanning both). Possible signs are sunburn with itching, swelling and blistering.
Drug interactions
Tell your doctor or pharmacist before use if you are taking, or have recently taken, any regular medication on prescription or over the counter products.
Fertility, Pregnancy and Lactation
- Use only on advice of your doctor or pharmacist before use if you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby.
- Do not use if you are in the last 3 months of pregnancy, as it could harm your unborn child or cause problems at delivery.
Overdose
If you swallow this medicine: Seek medical advice immediately.
The low systemic absorption of diclofenac when applied topically makes overdose more unlikely.
Treatment of overdose
In the event of accidental ingestion, resulting in significant systemic adverse effects, general therapeutic measures normally adopted to treat poisoning with non-steroidal anti- inflammatory medicines should be used. Further management should be as clinically indicated or as recommended by the national poisons centres where available.
Pharmacological Properties
Pharmacological action
Voltaren Emulgel is a non-steroidal anti-inflammatory topical gel
Mechanism of action
Diclofenac is a potent non-steroidal anti-inflammatory drug (NSAID) with effective analgesic, anti-inflammatory and antipyretic properties. Diclofenac exerts its therapeutic effects primarily through inhibition of prostaglandin synthesis.
Relevant pharmacokinetic data
Absorption: The quantity of diclofenac absorbed through the skin is proportional to the size of the treated area, and depends on both the total dose applied and the degree of skin hydration. Absorption amounts to about 6% of the applied dose of diclofenac after topical application of 2.5 g Voltaren Emulgel on 500 cm² skin, determined by total renal elimination, compared with Voltaren tablets. A 10-hour occlusion leads to a three-fold increase in the amount of diclofenac absorbed.
Distribution: 99.7% of diclofenac is bound to serum proteins, mainly albumin (99.4%).
Diclofenac concentrations have been measured from plasma, synovial tissue and synovial fluid after topical administration of a diclofenac diethylamine gel to hand and knee joints. Maximum plasma concentrations are approximately 100 times lower than after oral administration of the same quantity of diclofenac. Diclofenac accumulates in the skin which acts as reservoir from where there is a sustained release of drug into underlying tissues. From the skin and underlying tissue, diclofenac preferentially distributes and persists in deep inflamed tissues (such as the joint), rather than in the bloodstream. Diclofenac is found in tissues at concentrations up to 20 times higher than in plasma.
Metabolism: The biotransformation of diclofenac involves single and multiple hydroxylation steps followed by glucuronidation, and glucuronidation of the intact molecule.
Elimination: Diclofenac and its metabolites are excreted mainly in the urine.
The total systemic clearance of diclofenac from plasma is 263±56 ml/min. The terminal plasma half-life is 1-2 hours. Four of the metabolites, including the two active ones, also have short plasma half-lives of 1-3 hours. One metabolite, 3'-hydroxy-4'-methoxy-diclofenac, has a longer half-life but is virtually inactive.
Special Patient Populations
Renal and hepatic impairment
No accumulation of diclofenac and its metabolites is to be expected in patients suffering from renal impairment. In patients with chronic hepatitis or non-decompensated cirrhosis, the kinetics and metabolism of diclofenac are the same as in patients without liver disease.
