Voltarol ONE A DAY Medicated Plaster is a medicine that relieves pain. It belongs to a group of medicines known as non-steroidal anti-inflammatory drugs (NSAIDs).

Voltarol ONE A DAY Medicated Plaster is used for the local symptomatic short-term treatment (max. 7 days) of pain associated with acute strains, sprains or bruises on the arms and legs as a result of blunt injuries in adolescents from 16 years of age and adults.

2. What you need to know before you use Voltarol ONE A DAY Medicated Plaster

Do not use Voltarol ONE A DAY Medicated Plaster

  • if you are allergic to diclofenac or any of the other

    ingredients of this medicine (listed in section 6); - if you are allergic to any other non-steroidal

    anti-inflammatory drug (NSAID, e.g. acetylsalicylic acid or ibuprofen);

  • if you have ever developed asthma attacks, hives or swelling

    and irritation inside the nose after taking acetylsalicylic acid or any other NSAID;

  • if you are suffering from an active stomach or duodenal

    ulcer;

  • on injured skin (e.g. skin abrasions, cuts, burns), infected skin

    or skin affected by inflammation (exudative dermatitis) or eczema.

  • if you are in the last three months of pregnancy; - if you are a child or an adolescent younger than 16 years of age. Warnings and precautions

Talk to your doctor or pharmacist before using Voltarol ONE A DAY Medicated Plaster

  • if you suffer or have previously suffered from bronchial

    asthma or allergies; you may experience a bronchial muscle cramp (bronchospasm), which makes breathing difficult. • if you notice a skin rash that develops after applying the

    medicated plaster. If this happens, immediately remove the medicated plaster and stop the treatment.

  • if you suffer from disorders of the kidneys, heart or liver, or

    have previously suffered from a stomach or intestinal ulcer or intestinal inflammation or a tendency to bleeding.

    Side effects can be reduced by using the lowest effective dose for the shortest possible period of time.

    Important precautions

    • the medicated plaster must not come into contact with or be applied to the eyes or mucous membranes.
    • elderly patients should use Voltarol ONE A DAY Medicated

      Plaster with caution because they are more likely to experience side effects.

After taking off the medicated plaster, avoid exposing the treated area to direct sunlight or solarium radiation in order to reduce the risk of sensitivity to light.

Do not use Voltarol ONE A DAY Medicated Plaster at the same time as any other diclofenac-containing or other non-steroidal pain-relieving and anti-inflammatory medicines regardless of whether these are used externally or taken by mouth. Children and adolescents

Diclofenac is contraindicated for use in children and adolescents under 16 years of age. There are insufficient data of efficacy and safety available for children and adolescents below 16 years (see section Do not use Voltarol ONE A DAY Medicated Plaster). Other medicines and Voltarol ONE A DAY Medicated Plaster

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.

Provided that Voltarol ONE A DAY Medicated Plaster is used correctly, only a small amount of diclofenac is absorbed into the body so that the interactions described for diclofenac-containing medicines taken orally are unlikely to happen.

Pregnancy and breast-feeding

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before using this medicine. Pregnancy

In the first and second trimesters of pregnancy or if you want to become pregnant, Voltarol ONE A DAY Medicated Plaster should be used only after talking to your doctor.

In the last trimester of pregnancy, Voltarol ONE A DAY Medicated Plaster must not be used because an increased risk of complications for the mother and the child cannot be ruled out (see ”Do not use Voltarol ONE A DAY Medicated Plaster”). Breast-feeding

Small quantities of diclofenac pass into the breast milk. Talk to your doctor before using Voltarol ONE A DAY Medicated Plaster during breast-feeding. In any case, if you are breast-feeding Voltarol ONE A DAY Medicated Plaster should not be applied directly onto the breast area.

Oral forms (e.g. tablets) of diclofenac can cause adverse effects in your unborn baby. It is not known if the same risk applies to diclofenac when it is used on the skin.

Voltarol ONE A DAY Medicated Plaster has no influence on your ability to drive and use machines.

Voltarol ONE A DAY Medicated Plaster contains butylated hydroxyanisole (E320)

4. Possible side effects

Like all medicines, this medicine can cause side effects, although not everybody gets them.

Tell your doctor immediately and stop using the plaster if you notice any of the following:

sudden itchy rash (hives); swelling of the hands, feet, ankles, face, lips, mouth or throat; difficulty breathing; drop in blood pressure or weakness.

You may experience the following side effects:

Common side effects (may affect up to 1 in 10 people):

local skin reactions, such as skin redness, burning sensation, itching, inflamed skin redness, skin rash, sometimes with pustules or wheals.

Very rare side effects (may affect up to 1 in 10,000 people):

hypersensitivity reactions or local allergic reactions (contact dermatitis).

In patients externally using medicines from the same active substance group as diclofenac, there have been isolated reports of generalised skin rash, hypersensitivity reactions such as swelling of the skin and mucous membranes and

anaphylactic-type reactions with acute circulatory regulation disorders and light sensitivity reactions.

Absorption of diclofenac into the body by the skin is very low compared to the concentration of active substance in the blood following oral use of diclofenac. Therefore, the likelihood of side effects occurring in the body as a whole (such as gastrointestinal or kidney disturbances or difficulty breathing) is very low. Reporting of side effects

If you get any side effects, talk to your doctor or pharmacist. This includes any possible side effects not listed in this leaflet. You can also report side effects directly via the Yellow card scheme at www.mhra.gov.uk/yellowcard or search for MHRA Yellow Card in the Google Play or Apple App store. By reporting side effects you can help provide more information on the safety of this medicine.
