Patient leaflet - Voltarol suppositories 25 mg
1. What Voltarol Suppositories are and what they are used for
Diclofenac sodium, the active ingredient in Voltarol Suppositories, is one of a group of medicines called non-steroidal anti-inflammatory drugs (NSAIDs). NSAIDs reduce pain and inflammation.
Voltarol Suppositories relieve pain, reduce
swelling and ease inflammation in conditions affecting the joints, muscles and tendons including:
Rheumatoid arthritis, osteoarthritis, acute
gout, ankylosing spondylitis
Backache, sprains and strains, soft
tissue sports injuries, frozen shoulder, dislocations and fractures
- Tendonitis, tenosynovitis, bursitis.
They are also used to treat pain and
inflammation associated with dental and minor surgery.
In children aged 1 to 12 Voltarol
Suppositories 12.5 and 25 mg are used to treat juvenile chronic arthritis.
In children aged over 6 they can also be
used alone, or in combination with other painkillers, for the short term treatment of any pain experienced after an operation.

Pregnancy, breast-feeding and fertility
Do not use Voltarol Suppositories if you
are in the last 3 months of pregnancy as it could harm your unborn child or cause problems at delivery. It can cause kidney and heart problems in your unborn baby. It may affect your and your baby’s tendency to bleed and cause labour to be later or longer than expected. You should not use Voltarol Suppositories during the first 6 months
of pregnancy unless absolutely necessary and advised by your doctor. If you need treatment during this period or while you are trying to get pregnant, the lowest dose for the shortest time possible should be used. If used for more than a few days from 20 weeks of pregnancy onward, Voltarol Suppositories can cause kidney problems in your unborn baby that may lead to low levels of amniotic fluid that surrounds the baby (oligohydramnios) or narrowing of a blood vessel (ductus arteriosus) in the heart of the baby. If you need treatment for longer than a few days, your doctor may recommend additional monitoring.
Are you trying for a baby? Using Voltarol
Suppositories 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?
Very occasionally people have reported that Voltarol Suppositories have made them feel dizzy, tired or sleepy. Problems 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.
If at any time while taking Voltarol you
experience any signs or symptoms of problems with your heart or blood vessels such as chest pain, shortness of breath, weakness, or slurring of speech, contact your doctor immediately.
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.
If you have ever developed a severe skin
rash or skin peeling, blistering and/or mouth sores after taking Voltarol Suppositories or other pain medications.
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.
VOLTAROL Suppositories 50 mg and
100 mg are not suitable for children.
- VOLTAROL Suppositories 12.5 mg are not used for adults.

Technical approval by Packaging Site not using OneArt: electronic or handwritten signature. (If handwritten, it must be legible, include the approver’s full name and date of approval) Children
For the treatment of chronic juvenile arthritis in
children aged 1 to 12:
Doses vary with age, but are usually between
1 and 3 mg/kg body weight every day divided into
2 or 3 doses.
For the treatment of post-operative pain in children
aged 6 and over:
Doses vary with age, but are usually between
1 and 2 mg/kg body weight per day divided into
2 or 3 doses for no more than 4 days.
Your child’s doctor will work out the dose that is
suitable for your child and will tell you how many
Voltarol Suppositories to use and how often.
Follow his/her instructions carefully. If you are not
sure about the dose, check with your doctor or
pharmacist.
How to insert the suppositories
Empty your bowels before inserting
a suppository.
- Wash your hands.
Take out the strip of suppositories and tear off
one along the perforation.
Then take the suppository out of the plastic
wrapping by pulling back the loose end.
Lie on one side with your knees pulled up
towards your chest.
Gently push the suppository pointed end
first into your back passage (rectum) with your finger. Push the suppository in as far as possible as shown in the diagram.
Lower your legs and, if possible, stay still for
a few minutes.
If you feel as if you need to push the suppository
out, try to resist this by lying still with your buttocks pressed together. It is important to keep the suppository in the rectum to allow it to melt and the medicine to be absorbed. Pushing the suppository high into the rectum with your finger will help to reduce this feeling.
- Wash your hands.
The procedure is the same for a child. Once they have emptied their bowels, get them to lie down on their front or side. Gently push the suppository into the child’s back passage until it disappears. Try and stop the child moving around for a few minutes to reduce the risk of the suppository coming out. What if you forget to take a dose?
If you forget to use a suppository, do not worry. Use one as soon as you remember. If it is nearly time for your next dose though, just take the next dose and forget about the one you missed. Do not double up the next dose to make up for the one you missed. Do not insert 2 suppositories at the same time. The total dose should not be
more than 150 mg each day if you are an adult. Children should not take more than the dose that is prescribed by their doctor.
What if you use too many suppositories?
You should not take more than 150 mg in one day if you are an adult. Children should not take more than the dose that is prescribed by their doctor. If you accidentally use too many suppositories or use them too often, tell your doctor or go to your nearest casualty department straight away.
