What is Diclofenac?
Diclofenac Sodium is a non-steroidal anti-inflammatory medicine used for the treatment of inflammation and swelling. It can also provide pain relief, and help reduce other symptoms caused by various joint conditions and health problems.
These include rheumatoid arthritis, osteoarthritis and gout, as well as sprains and strains, back pain, soft tissue injuries and migraines. Diclofenac is also used to treat ankylosing spondylitis, which is a condition causing inflammation of the spine.
Diclofenac is available on prescription, and you must have been prescribed Diclofenac before you can order it. Diclofenac plasters and gel are available from your pharmacist. It's also possible to buy Diclofenac online through an online doctor or pharmacy.
Diclofenac is known by several brand names - Fenactol, Econac, Dicloflex and Voltarol. You can read the patient information leaflet for Diclofenac here.
Diclofenac is one of a group of medicines called non-steroidal anti-inflammatory medicines. It works by inhibiting a particular type of hormone that causes pain and inflammation. Therefore, the sensation of pain and inflammation is reduced or eliminated.
Diclofenac usually takes 20 to 30 minutes to work if it is taken as tablets. Suppositories usually take several hours to work.
Diclofenac is also manufactured as a gel, for administration on the skin. This usually takes up to two days to become effective.
Before you take it
Diclofenac can be taken by most people, including most adults and some children.
Diclofenac is typically only prescribed to children for joint problems. It can be taken by children over one year old as tablets, suppositories and capsules.
Diclofenac is unsuitable for you if you have an allergy to aspirin, if you have high blood pressure or if you've ever shown any symptoms of heart failure, liver disease or kidney disease. It may also not be suitable for long term use - your doctor may suggest a different NSAID, such as naproxen or ibuprofen.
Diclofenac may be unsuitable for people with diabetes, high cholesterol or high blood pressure. You should not take Diclofenac without consulting your doctor in this case.
You should not take Diclofenac if you have a history of internal bleeding, if you've ever had a stroke, or have a blood clotting disorder. Diclofenac is not suitable for anyone who has had an allergic reaction to any kind of non-steroidal anti inflammatory drugs (NSAIDS) or medicines in the past.
If you're pregnant, trying to get pregnant or breastfeeding, you need to inform your doctor before taking Diclofenac. Taking this medicine can increase the risk of miscarriage. If used during the first and last trimesters of pregnancy, it can interfere with labour and delivery, and can possibly cause harm to your baby. It is not recommended to use diclofenac while pregnant.
It’s safe to take other painkillers such as paracetamol and codeine with Diclofenac.
If you're in any doubt, you must consult your pharmacist or doctor.
You should take Diclofenac as prescribed by your doctor or pharmacist.
A typical dose is between 75 mg and 150 mg per day, divided between three doses. Your doctor or pharmacist will advise you on how many tablets to take and exactly when to take them.
Slow-release Diclofenac can also be prescribed for those who are experiencing constant pain. It's normal to take this medication either once or twice a day.
If you're elderly, a doctor may require you take a lower dosage and may monitor you closely to observe the medicine's effects. For children, the child's weight must be taken into account so that they are given the correct dosage. Your doctor will support you in calculating this.
Take Diclofenac by swallowing the pill whole with water. Do not crush, chew or suck it. Suppositories should be inserted into your back passage roughly three centimetres deep, and then allowed to melt. The medicine is absorbed through the lining of the skin.
For Diclofenac gel, release a small amount of gel from the tube or dispenser and rub it onto the affected area. It will feel cool on your skin - wash your hands afterwards. Depending on the gel's strength, you will typically need to use it 2-4 times a day. Don't use it more than 4 times in a 24 hour period.
