Children and Adolescents:
Voltarol Extra Strength 25mg Tablets are not to be used in children and
adolescents under 14 years of age.
Undesirable effects may be minimised by using the lowest effective dose for
the shortest duration necessary to control symptoms (see section 4.4 Special
warnings and precautions for use).

4.3

Contraindications
• Known hypersensitivity to diclofenac or to any of the excipients. Patients
in whom attacks of asthma, urticaria, angioedema, or acute rhinitis are
precipitated by aspirin or other non-steroidal anti-inflammatory drugs such
as ibuprofen.




Pregnancy or breastfeeding (see section 4.6 Pregnancy and lactation).



Severe hepatic or renal failure (see section 4.4 Special warnings and
special precautions for use).



Established congestive heart failure (NYHA II-IV), ischemic heart disease,
peripheral arterial disease and/or cerebrovascular disease



Concomitant use of anticoagulants and antiplatelets (see section 4.5
Interactions)



4.4

Gastric or intestinal ulcer, bleeding or perforation.

Use with concomitant NSAIDs including cyclo-oxygenase-2 specific
inhibitors (see section 4.5 Interactions)

Special warnings and precautions for use
Warnings
Gastrointestinal bleeding, ulceration or perforation, which can be fatal, have
been reported with all NSAIDs and may occur at any time during treatment,
with or without warning symptoms or a previous history of serious
gastrointestinal events. They generally have more serious consequences in the
elderly. If gastrointestinal bleeding or ulceration occur in patients receiving
diclofenac, the medicinal product should be withdrawn.
Serious skin reactions, some of them fatal, including exfoliative dermatitis,
Stevens-Johnson syndrome and toxic epidermal necrolysis, have been reported
very rarely in association with the use of NSAIDs, including diclofenac (see
section 4.8 Undesirable effects). Patients appear to be at highest risk of these
reactions early in the course of therapy, the onset of the reaction occurring in
the majority of cases within the first month of treatment. Diclofenac should be
discontinued at the first appearance of skin rash, mucosal lesions or any other
sign of hypersensitivity.
As with other NSAIDs, allergic reactions, including
anaphylactic/anaphylactoid reactions, can occur in rare cases without earlier
exposure to diclofenac.
In common with other NSAIDs, diclofenac may mask the signs and symptoms
of infection due to its pharmacodynamic properties.
Patients with rare hereditary problems of fructose intolerance, glucosegalactose malabsorption or sucrase-isomaltase insufficiency should not take
this medicine.
Precautions
General
Undesirable effects may be minimised by using the lowest effective dose for
the shortest duration necessary to control symptoms (see GI and
Cardiovascular risks below).
The concomitant use of diclofenac with systemic NSAIDs, including
cyclooxygenase-2 selective inhibitors, should be avoided due to the absence of
any evidence demonstrating synergistic benefits and the potential for additive
undesirable effects.

Caution is indicated in the elderly. In particular, it is recommended that the
lowest effective dose be used in frail elderly patients or those with a low body
weight.
Caution (discussion with doctor or pharmacist) is required prior to starting
treatment in patients with a history of hypertension and/or heart failure as fluid
retention, hypertension and oedema have been reported in association with
NSAIDs therapy (see Renal effects below).
Pre-existing asthma
In patients with asthma, seasonal allergic rhinitis, swelling of nasal mucosa
(i.e. nasal polypus), chronic obstructive pulmonary disease or chronic
infection of the respiratory tract (especially if linked to allergic rhinitis-like
symptoms), reactions to NSAIDs such as asthma exacerbations (so-called
intolerance to analgesics / analgesics-asthma), angioedema or urticaria are
more frequent than in other patients.

Gastrointestinal effects
As with all NSAIDs, close medical surveillance is imperative and caution
should be exercised when prescribing diclofenac in patients with symptoms
indicative of gastrointestinal (GI) disorders or with a history suggestive of
gastric or intestinal ulceration, bleeding or perforation (see section 4.8
Undesirable effects). The risk of GI bleeding is higher with increasing NSAID
doses and in patients with a history of ulcer, particularly if complicated with
haemorrhage or perforation and in the elderly.
Patients with a history of GI toxicity, particularly the elderly, should report
any unusual abdominal symptoms (especially GI bleeding). Caution is
recommended in patients receiving concomitant medications which could
increase the risk of ulceration or bleeding, such as systemic corticosteroids,
anticoagulants, anti-platelet agents or selective serotonin-reuptake inhibitors
(see section 4.5 Interaction with other medicinal products and other forms of
interaction).
Close medical surveillance should also be exercised in patients with ulcerative
colitis or Crohn's disease, as their condition may be exacerbated (see section
4.8 Undesirable effects).
Cardiovascular and cerebrovascular effects
Patients with significant risk factors for cardiovascular events (e.g.
hypertension, hyperlipidaemia, diabetes mellitus and smoking) should only be
treated with diclofenac after careful consideration.
As the cardiovascular risks of diclofenac may increase with dose and duration
of exposure, the shortest duration possible and the lowest effective daily dose
should be used. The patient's need for symptomatic relief and response to
therapy should be re-evaluated periodically. Patients should be advised to seek
further medical advice if symptoms persist or do not improve within the
recommended duration of treatment.

Clinical trial and epidemiological data consistently point towards an increased
risk of arterial thrombotic events (for example myocardial infarction or stroke)
associated with the use of diclofenac, particularly at high dose (150 mg daily)
and in long-term treatment. Available data do not suggest an increased risk
with use of low dose diclofenac (up to 75 mg/day) up to 3 days for relief of
pain or fever.
Hepatic effects
Close medical surveillance is required when prescribing diclofenac to patients
with impaired hepatic function, as their condition may be exacerbated.
As with other NSAIDs, values of one or more liver enzymes may increase. In
the case of diclofenac being prescribed for a prolonged period, regular
monitoring of hepatic function is indicated as a precautionary measure. If
abnormal liver function tests persist or worsen, if clinical signs or symptoms
consistent with liver disease develop, or if other manifestations occur (e.g.
eosinophilia, rash), diclofenac should be discontinued. Hepatitis may occur
without prodromal symptoms.
Caution is called for when using diclofenac in patients with hepatic porphyria,
since it may trigger an attack.
Renal effects
Caution is called for in patients with impaired renal function, particularly the
elderly and patients receiving concomitant treatment with diuretics or
medicinal products that can significantly impact renal function and in those
patients with substantial extracellular volume depletion.
As fluid retention and oedema have been reported in association with NSAID
therapy, particular caution is called for in elderly patients receiving
concomitant treatment with diuretics or medicinal products that can
significantly impact renal function, and in those patients with substantial
extracellular volume depletion from any cause, e.g. before or after major
surgery (see section 4.3 Contraindications). Monitoring of renal function is
recommended as a precautionary measure when using diclofenac in such
cases. Discontinuation of therapy is usually followed by recovery to the pretreatment state.
Haematological effects
Like other NSAIDs, diclofenac may temporarily inhibit platelet aggregation.
Patients with defects of haemostasis should be carefully monitored.
Dermatological effects
Serious skin reactions, some of them fatal, including exfoliative dermatitis,
Stevens Johnson syndrome, and toxic epidermal necrolysis, have been
reported very rarely in association with the use of NSAIDs (see section 4.8).
Patients appear to be at highest risk for these reactions early in the course of
therapy: the onset of the reaction occurring in the majority of cases within the
first month of treatment. Voltarol Pain-eze Extra Strength 25mg Tablets
should be discontinued at the first appearance of skin rash, mucosal lesions, or
any other sign of hypersensitivity.

Interaction with other medicinal products and other forms of interaction
Lithium and digoxin: Diclofenac may increase plasma concentrations of
lithium and digoxin.
Diuretics and antihypertensive agents: Like other NSAIDs, concomitant use
of diclofenac with diuretics or antihypertensive agents (e.g. beta-blockers,
angiotensin converting enzyme (ACE) inhibitors) may cause a decrease in
their antihypertensive effect. Therefore, the combination should be
administered with caution and patients, especially the elderly, should have
their blood pressure periodically monitored. Patients should be adequately
hydrated and consideration should be given to monitoring of renal function
after initiation of concomitant therapy and periodically thereafter, particularly
for diuretics and ACE inhibitors due to the increased risk of nephrotoxicity.
Concomitant treatment with potassium-sparing diuretics may be associated
with increased serum potassium levels, which should therefore be monitored
frequently (see section 4.4 Special warnings and special precautions for use).
Other NSAIDs including cyclooxygenase-2 selective inhibitors and
corticosteroids:
Co-administration of diclofenac with aspirin or corticosteroids may increase
the risk of gastrointestinal bleeding or ulceration. Avoid concomitant use of
two or more NSAIDs (see section 4.4 Special warnings and special
precautions for use).
Selective serotonin reuptake inhibitors (SSRIs) and anti-platelet agents:
Increased risk of gastrointestinal bleeding (see section 4.4 Special warnings
and special precautions for use).
Antidiabetics: Clinical studies have shown that diclofenac can be given
together with oral antidiabetic agents without influencing their clinical effect.
However, there have been isolated reports of both hypoglycaemic and
hyperglycaemic effects necessitating changes in the dosage of the antidiabetic

agents during treatment with diclofenac. Monitoring of the blood glucose
level is recommended as a precautionary measure during concomitant therapy.
Methotrexate: Caution is recommended when NSAIDs are administered less
than 24 hours before or after treatment with methotrexate, since blood
concentrations of methotrexate may rise and the toxicity of this substance be
increased.
Ciclosporin and tacrolimus: Diclofenac, like other NSAIDs, may increase the
nephrotoxicity of ciclosporin due to the effect on renal prostaglandins.
Therefore, it should be given at doses lower than those that would be used in
patients not receiving ciclosporin or tacrolimus.
Quinolone antibacterials: There have been isolated reports of convulsions
which may have been due to concomitant use of quinolones and NSAIDs.
4.6

Fertility, pregnancy and lactation
Pregnancy
The use of diclofenac in pregnant women has not been studied. Therefore,
Voltarol Pain-eze Extra Strength 25mg Tablets should not be used during
pregnancy except on the advice of a doctor.
Lactation
Like other NSAIDs, diclofenac passes into the breast milk in small amounts.
Therefore, Voltarol Pain-eze Extra Strength 25mg Tablets should not be
administered during breast feeding in order to avoid undesirable effects in the
infant.
Fertility
As with other NSAIDs, the use of diclofenac may impair female fertility and is
not recommended in women attempting to conceive. In women who have
difficulties conceiving or who are undergoing investigation of infertility,
withdrawal of diclofenac should be considered.

4.7

Effects on ability to drive and use machines
Usually there is no effect at the recommended low-dose and short duration of
treatment. However patients experiencing visual disturbances, dizziness,
vertigo, somnolence or other central nervous system disturbances while taking
diclofenac should refrain from driving or using machines.

4.8

Undesirable effects
Adverse reactions (Table 1) are ranked under heading of frequency, the most
frequent first, using the following convention: common (≥ 1/100, < 1/10);
uncommon (≥ 1/1,000, < 1/100); rare (≥ 1/10,000, < 1/1,000); very rare (<
1/10,000), including isolated reports.

associated with the use of diclofenac, particularly at high dose (150mg daily)
and in long term treatment. (see section 4.3 and 4.4 for Contraindications and
Special warnings and special precautions for use).
4.9

Overdose
Symptoms
There is no typical clinical picture resulting from diclofenac overdosage.
Overdose can cause symptoms such as vomiting, gastrointestinal
haemorrhage, diarrhoea, dizziness, tinnitus or convulsions. In the event of
significant poisoning, acute renal failure and liver damage are possible.
Therapeutic measures
Management of acute poisoning with NSAIDs essentially consists of
supportive measures and symptomatic treatment. These should be given for
complications such as hypotension, renal failure, convulsions, gastrointestinal
disorder, and respiratory depression.
Special measures such as forced diuresis, dialysis or haemoperfusion are
probably of no help in eliminating NSAIDs due to the high protein binding
and extensive metabolism.
Activated charcoal may be considered in case of a potentially toxic overdose,
and gastric decontamination (e.g. vomiting, gastric lavage) in case of a
potentially life-threatening overdose.

PHARMACOLOGICAL PROPERTIES

5.1

Pharmacodynamic properties
Pharmacotherapeutic group: NSAID, ATC code: {M01 AB 05}
Voltarol Pain-eze Extra Strength 25mg Tablets contain the potassium salt of
diclofenac, a non-steroidal anti-inflammatory drug with pronounced analgesic
and anti-pyretic properties.
Voltarol Pain-eze Extra Strength 25mg Tablets have a rapid onset of action
and are therefore suitable for the treatment of acute episodes of pain and
inflammation.
In migraine attacks Diclofenac potassium has been shown to be effective in
relieving the headache and in improving the accompanying symptom of
nausea.
Diclofenac is a potent inhibitor of prostaglandin bio-synthesis and modulator
of arachidonic acid release and uptake.
Diclofenac possesses clinically demonstrable analgesic, antipyretic and antiinflammatory effects.
Diclofenac in vitro does not suppress proteoglycan biosynthesis in cartilage at
concentrations equivalent to the concentrations reached in human beings.

5.2

Pharmacokinetic properties
Absorption
Diclofenac is rapidly and completely absorbed from sugar-coated tablets.
Food intake does not affect absorption.
Peak plasma concentration after one 50mg sugar-coated tablet was 3.9 mmol/l
after 20-60 minutes. The plasma concentrations show a linear relationship to
the size of the dose.
Diclofenac undergoes first-pass metabolism and is extensively metabolised.
Distribution
Diclofenac is highly bound to plasma proteins (99.7%), chiefly albumin
(99.4%).
Elimination
The total systemic clearance of diclofenac in plasma is 263 + 56 ml/min (mean
+ SD).
The terminal half life in plasma is 1-2 hours.
Repeated oral administration of Voltarol Pain-eze Extra Strength 25mg
Tablets for 8 days in daily doses of 50mg three times a day does not lead to
accumulation of diclofenac in the plasma.
Approximately 60% of the dose administered is excreted in the urine in the
form of metabolites, and less than 1% as unchanged substance. The remainder
of the dose is eliminated as metabolites through the bile in the faeces.
Biotransformation
The biotransformation of diclofenac involves partly glucuronidation of the
intact molecule but mainly single and multiple hydroxylation followed by
glucuronidation.
In patients suffering from renal impairment, no accumulation of the unchanged
active substance can be inferred from the single-dose kinetics when applying
the usual dosage schedule. At a creatinine clearance of <10 ml/min the
theoretical steady-state plasma levels of metabolites are about four times
higher than in normal subjects. However, the metabolites are ultimately
cleared through the bile.
Characteristics in patients:
The age of the patient has no influence on the absorption, metabolism, or
excretion of diclofenac.
In the presence of impaired hepatic function (chronic hepatitis, nondecompensated cirrhosis) the kinetics and metabolism are the same as for
patients without liver disease.
