1. WHAT VOLTAROL RAPID TABLETS ARE AND WHAT THEY ARE USED FOR
Diclofenac potassium, the active ingredient in Voltarol Rapid Tablets, is one of a group of medicines called nonsteroidal anti-inflammatory drugs (NSAIDs). NSAIDs reduce pain and inflammation.
Voltarol Rapid Tablets relieve pain, reduce swelling and ease inflammation in:
• Rheumatoid arthritis, osteoarthrosis, acute gout, low back pain, ankylosing spondolytis
• Conditions affecting the joints and muscles such as sprains and strains, soft tissue sports injuries, frozen
shoulder, dislocations, and fractures
• Conditions affecting the tendons for example, tendonitis, tenosynovitis, bursitis.
They are also used to treat pain and inflammation associated with orthopaedic, dental and other minor surgery.
2. THINGS TO CONSIDER BEFORE YOU START TO TAKE VOLTAROL RAPID TABLETS
Some people MUST NOT take Voltarol Rapid Tablets.
Talk to your doctor if:
• you think you may be allergic to diclofenac potassium, aspirin, ibuprofen or any other NSAID, or to any of the
other ingredients of Voltarol Rapid Tablets. (These are listed at the end of the leaflet.) Signs of a
hypersensitivity reaction include swelling of the face and mouth (angioedema), breathing problems, runny nose,
skin rash or any other allergic type reaction
• you have now, or have ever had, a stomach (gastric) or duodenal (peptic) ulcer, or bleeding in the digestive tract
(this can include blood in vomit, bleeding when emptying bowels, fresh blood in faeces or black, tarry faeces)
• you have had stomach or bowel problems after you have taken other NSAIDs
• you have severe heart, kidney or liver failure
• if you have established heart disease and/or cerebrovascular disease e.g. if you have had a heart attack,
stroke, mini-stroke (TIA) or blockages to blood vessels to the heart or brain or an operation to clear or bypass
• if you have or have had problems with your blood circulation (peripheral arterial disease)
• you are more than six months pregnant.

• Do you have kidney or liver problems, or are you elderly?

• Have you ever had asthma?
• Are you breast-feeding?
• Do you have angina, blood clots, high blood pressure, raised cholesterol or raised triglycerides?

• Do you have Lupus (SLE) or any similar condition?

• Are you pregnant or planning to become pregnant? Although not common, abnormalities have been reported in
babies whose mothers have taken NSAIDs during pregnancy. You should not take Voltarol Rapid Tablets
during the last 3 months of pregnancy as it may affect the baby’s circulation.
• Are you trying for a baby? Taking Voltarol Rapid Tablets may make it more difficult to conceive. You should talk
to your doctor if you are planning to become pregnant, or if you have problems getting pregnant.
Will there be any problems with driving or using machinery?

with eyesight have also been reported. If you are affected in this way, you should not drive or operate machinery.
Other special warnings
• You should take the lowest dose of Voltarol for the shortest possible time, particularly if you are underweight or elderly.
• There is a small increased risk of heart attack or stroke when you are taking any medicine like Voltarol. The risk
is higher if you are taking high doses for a long time. Always follow the doctor’s instructions on how much to
take and how long to take it for.
• Whilst you are taking these medicines your doctor may want to give you a check-up from time to time.
• If you have a history of stomach problems when you are taking NSAIDs, particularly if you are elderly, you must
tell your doctor straight away if you notice any unusual symptoms.
• Because it is an anti-inflammatory medicine, Voltarol may reduce the symptoms of infection, for example,
headache and high temperature. If you feel unwell and need to see a doctor, remember to tell him or her that
you are taking Voltarol.
