Health Centres - Voltarol gel patch
How does it work?
Voltarol gel patches contain the active ingredient diclofenac epolamine, which is a type of medicine called a non-steroidal anti-inflammatory drug (NSAID). NSAIDs are used to relieve pain and inflammation.
Diclofenac works by blocking the action of a substance in the body called cyclo-oxygenase (COX). Cyclo-oxygenase is involved in the production of various chemicals in the body, some of which are known as prostaglandins. Prostaglandins are produced by the body in response to injury and certain diseases and conditions, and cause pain, swelling and inflammation. Diclofenac blocks the production of these prostaglandins and is therefore effective at reducing inflammation and pain.
When diclofenac is applied to the skin (topical application) it is absorbed through the skin into the underlying tissues, where it reduces pain and inflammation in the local area.
Voltarol gel patches are used to relieve the pain and inflammation of tennis elbow (epicondylitis) and sprained ankles.
The patch is applied to the skin over the affected elbow or ankle. The diclofenac will be absorbed from the patch through the skin into the underlying tissues, where it will relieve pain and inflammation.
What is it used for?
- Pain and inflammation of sprained ankle
- Pain and inflammation of tennis elbow
Warning!
- Do not apply the patch to broken or diseased areas of skin, eg wounds, burns, infections, eczema, dermatitis.
- You should not cover the patch with airtight dressings such as bandages or other dressings, as these will enhance the absorption of the medicine into the body and may increase the risk of adverse effects.
- Avoid contact of the medicine with the eyes.
- Stop using the patches immediately if you get a skin rash and consult your doctor.
- When diclofenac is applied to the skin it is absorbed into the bloodstream to a far lesser degree than diclofenac taken by mouth. This means it is much less likely to cause side effects on the gut than oral diclofenac. However, it is important that people with a history of disorders affecting the stomach or intestines are closely monitored by a doctor while using this medicine, particularly if elderly. Consult your doctor immediately if you experience side effects such as stomach pain, indigestion, heartburn or signs of bleeding in the stomach or intestines, eg blood in the stools, while using this medicine.
- If symptoms persist despite treatment, seek medical advice from your doctor or pharmacist.
- You should avoid excessive exposure to bright sunlight while using this medicine, as it may increase the risk of sunburn.

Pregnancy and Breastfeeding
Certain medicines should not be used during pregnancy or breastfeeding. However, other medicines may be safely used in pregnancy or breastfeeding providing the benefits to the mother outweigh the risks to the unborn baby. Always inform your doctor if you are pregnant or planning a pregnancy, before using any medicine.
- This medicine is not recommended for use in pregnancy, particularly the third trimester. If diclofenac is taken in the third trimester it may delay labour, increase the length of labour and cause complications in the newborn baby. Seek medical advice from your doctor.
- When diclofenac is taken by mouth it passes into the breast milk, but at normal doses is unlikely to harm the baby. Seek medical advice from your doctor before using this medicine while breastfeeding.
