What Is the Voltarol 140mg Medicated Plaster?

 

The Voltarol 140mg medicated plaster is a topical, non-steroidal anti-inflammatory drug (NSAID) patch designed to deliver targeted pain relief directly to the affected area. Each plaster contains 140mg of diclofenac sodium — a well-established anti-inflammatory active ingredient — and is applied directly to the skin over sore muscles or aching joints. This pack contains two plasters, giving you two full applications for ongoing localised pain management. If you're looking for a convenient, mess-free alternative to gels or creams, this format is worth considering. You can explore a wider range of options in our pain relief collection.

Voltarol is one of the most recognised topical pain relief brands in the UK, and the medicated plaster format is particularly useful for people who find gels difficult to apply or who need sustained delivery over several hours. It's available over the counter without a prescription for adults and young people aged 16 and over.

 

How Does the Voltarol Medicated Plaster Work?

 

Diclofenac sodium, the active ingredient in this plaster, works by inhibiting the enzymes cyclo-oxygenase-1 (COX-1) and cyclo-oxygenase-2 (COX-2). These enzymes are responsible for producing prostaglandins — chemical messengers that trigger pain, swelling, and inflammation in the body. By blocking their production locally, the plaster helps reduce discomfort at the site of injury or inflammation without the same systemic exposure associated with oral NSAIDs.

  • Diclofenac penetrates the skin and underlying tissue at the application site
  • COX-1 and COX-2 enzyme activity is inhibited locally
  • Prostaglandin synthesis is reduced, lowering pain and swelling
  • The plaster maintains a steady release of the active ingredient over the wear period

Because the drug acts locally rather than being absorbed in large quantities into the bloodstream, the risk of systemic side effects — such as stomach irritation — is considerably lower than with oral diclofenac tablets.

 

Who Should Use the Voltarol 140mg Plaster?

 

This plaster is suitable for adults and young people aged 16 and over who are experiencing localised musculoskeletal pain. It's particularly well suited to people who prefer a hands-free, targeted approach to pain management — especially those who are active or need to continue daily tasks without reapplying a gel repeatedly throughout the day.

  • Adults with muscle strains or sprains
  • People with localised joint pain, such as knee or shoulder discomfort
  • Those with mild to moderate back pain
  • Individuals who find topical gels inconvenient or messy

It is not suitable for children under 16, and it should not be used by anyone with a known hypersensitivity to diclofenac or other NSAIDs, including aspirin. Always read the label before use.

 

How Does the Voltarol Plaster Compare to Topical Gel Alternatives?

 

Feature Voltarol 140mg Medicated Plaster Voltarol Emulgel (Topical Gel)
Active ingredient Diclofenac sodium 140mg Diclofenac diethylammonium 1.16%
Application method Adhesive patch — apply once, leave in place Rub gel into skin 3–4 times daily
Duration per application Up to 12 hours 4–6 hours per application
Suitable for active use Yes — stays in place during movement Less convenient during physical activity

 

Is the Voltarol Plaster Suitable for Sensitive Skin or Long-Term Use?

 

If you have sensitive skin, it's worth doing a small patch test before committing to full application. Some people experience mild skin reactions — such as redness or itching — at the application site. These are usually mild and resolve once the plaster is removed. The Voltarol 140mg medicated plaster should not be used for more than 14 days continuously without seeking medical advice. If your symptoms persist or worsen, speak to your GP. For those managing longer-term musculoskeletal conditions, our creams and ointments collection includes a range of topical options that may complement your pain management plan.

Store the plasters below 25°C, away from direct heat and sunlight, and keep them out of reach of children. Do not apply to broken, inflamed, or infected skin.

This product is a medicine. Speak to your doctor or pharmacist before using if you have an underlying medical condition or are taking other medicines.

Specifications of Voltarol 140mg Medicated Plaster

 

What Is the Voltarol 140mg Plaster and What Is It Used For?

 

The Voltarol 140mg Medicated Plaster is a topical NSAID containing diclofenac sodium. It is used to relieve localised pain and reduce inflammation in muscles and joints. Common uses include muscle strains, sprains, and mild to moderate joint pain — for example, in the knee, shoulder, or lower back. It is intended for short-term use in adults and young people aged 16 and over. It is not a cure for underlying conditions but provides symptomatic relief while the body heals.

 

What Do You Need to Know Before Using the Voltarol Plaster?

 

Before applying this plaster, it's important to check whether it is appropriate for you. There are several situations in which you should not use it, and a number of medicines that may interact with diclofenac even when applied topically.

Do not use this plaster if you:

  • Are allergic to diclofenac, aspirin, ibuprofen, or any other NSAID
  • Have previously experienced asthma, urticaria, or allergic reactions triggered by NSAIDs
  • Are in the third trimester of pregnancy (28 weeks or more)
  • Are under 16 years of age
  • Have broken, damaged, infected, or eczematous skin at the intended application site
  • Have a known sensitivity to any of the excipients listed in the patient information leaflet

Use with caution and speak to a pharmacist or GP if you:

  • Are pregnant (especially from 20 weeks onwards) or breastfeeding
  • Have a history of peptic ulcer disease or gastrointestinal bleeding
  • Have impaired kidney or liver function
  • Have heart failure or cardiovascular disease

Possible drug interactions include:

  • Anticoagulants such as warfarin — topical NSAIDs may slightly increase bleeding risk
  • Other NSAIDs (oral or topical) — concurrent use increases the risk of side effects
  • Lithium — diclofenac may increase plasma lithium levels
  • Methotrexate — NSAIDs may reduce its renal clearance

 

How Should You Use the Voltarol 140mg Plaster?

 

Using the plaster correctly ensures you get the most benefit while minimising the risk of skin irritation. Follow these steps carefully each time you apply a new plaster.

  1. Wash and thoroughly dry the area of skin where you intend to apply the plaster
  2. Open the sachet and remove the plaster
  3. Peel away the protective backing film from the plaster
  4. Apply the adhesive side firmly to the affected area of skin
  5. Press down gently around the edges to ensure good contact
  6. Leave the plaster in place for up to 12 hours
  7. Remove carefully and fold the used plaster in half (adhesive sides together) before disposing of it safely
  8. Wash your hands after handling the plaster
Indication Age Group Dose Frequency
Localised muscle or joint pain Adults and young people aged 16+ 1 plaster (140mg diclofenac sodium) Up to twice daily (every 12 hours); max 2 plasters per day
Not applicable Under 16 years Not recommended Not recommended

Do not apply more than two plasters in any 24-hour period. Do not use on the same area of skin continuously without allowing the skin to rest. If you are also using other topical pain relief products, browse our first aid collection for complementary options.

 

What Are the Possible Side Effects of the Voltarol Plaster?

 

Like all medicines, the Voltarol 140mg Medicated Plaster can cause side effects, although not everyone experiences them. Because the active ingredient is applied topically, systemic side effects are much less likely than with oral NSAIDs. Most reactions are localised to the skin at the application site.

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

  • Skin redness (erythema) at the application site
  • Itching or pruritus
  • Mild burning or stinging sensation
  • Skin rash at the site of application

Less common side effects (may affect up to 1 in 100 people):

  • Contact dermatitis
  • Dry or flaking skin at the application site
  • Localised swelling or oedema
  • Photosensitivity reaction if the treated area is exposed to sunlight

Serious systemic side effects — such as gastrointestinal bleeding, kidney problems, or severe allergic reactions — are rare with topical use but have been reported. Stop using the plaster and seek medical attention immediately if you develop signs of a severe allergic reaction, such as facial swelling, difficulty breathing, or widespread skin rash.

 

How Should You Store the Voltarol 140mg Plaster?

 

  • Store below 25°C in a cool, dry place
  • Keep away from direct heat sources and sunlight
  • Keep the plasters in their original sealed sachets until use
  • Keep out of the sight and reach of children
  • Do not use after the expiry date printed on the packaging
  • Do not dispose of medicines via wastewater or household waste — return unused plasters to your pharmacy

Frequently Asked Questions

Where can I buy Voltarol 140mg medicated plaster online in the UK?

You can buy the Voltarol 140mg Medicated Plaster directly from Cured Pharmacy, a GPhC-registered UK online pharmacy. It is available without a prescription as an over-the-counter medicine. Simply add it to your basket and it will be dispatched to your door.

How does the Voltarol 140mg medicated plaster work in the body?

The plaster contains diclofenac sodium, an NSAID that inhibits COX-1 and COX-2 enzymes responsible for producing prostaglandins — the chemicals that cause pain and inflammation. Because it is applied topically, the drug acts locally at the site of pain rather than throughout the whole body. This means systemic side effects are considerably less likely than with oral NSAIDs.

How do I apply the Voltarol plaster step by step?

Clean and dry the affected area of skin first. Peel away the protective backing film and press the adhesive side of the plaster firmly onto the skin, smoothing down the edges. Leave it in place for up to 12 hours, then remove and dispose of it safely by folding the used plaster in half before placing it in the bin.

How long does it take for the Voltarol plaster to start working?

Some people notice a reduction in pain within a few hours of applying the plaster, though the full anti-inflammatory effect may take longer to develop. Individual response times vary depending on the nature and severity of the pain. If you notice no improvement after several days of use, speak to your pharmacist or GP.

What is the correct dose of the Voltarol 140mg plaster?

The recommended dose is one plaster applied to the affected area, worn for up to 12 hours. You may apply up to two plasters in a 24-hour period, but do not exceed this. The plaster is only suitable for adults and young people aged 16 and over — it should not be used in children under 16.

Can I use the Voltarol plaster if I am pregnant or breastfeeding?

The Voltarol medicated plaster is not recommended during pregnancy, particularly from 20 weeks onwards, as diclofenac may affect fetal kidney function and reduce amniotic fluid levels. If you are breastfeeding, speak to your GP or pharmacist before use, as small amounts of diclofenac may pass into breast milk. Always seek professional advice before using any NSAID during pregnancy or whilst breastfeeding.

What are the side effects of the Voltarol 140mg medicated plaster?

The most common side effects are localised skin reactions at the application site, including redness, itching, and mild burning. Less commonly, contact dermatitis or photosensitivity may occur. Serious systemic side effects are rare with topical use, but if you develop signs of a severe allergic reaction — such as facial swelling or difficulty breathing — remove the plaster and seek urgent medical attention.

Who is eligible to use the Voltarol 140mg plaster?

The plaster is suitable for adults and young people aged 16 and over who have localised muscle or joint pain. It is not suitable for anyone with a known allergy to diclofenac or other NSAIDs, those with broken or infected skin at the application site, or those in the third trimester of pregnancy. If you have kidney, liver, or heart conditions, speak to your GP before use. You can browse our wider pain relief collection for alternative options if this product is not suitable for you.

What happens if I forget to change my Voltarol plaster?

If you forget to replace your plaster after 12 hours, simply apply a new one when you remember. Do not apply two plasters at the same time to make up for a missed application. Stick to the maximum of two plasters in any 24-hour period and continue as normal.

How long can I use the Voltarol plaster for?

The Voltarol 140mg Medicated Plaster is intended for short-term use only and should not be used continuously for more than 14 days without medical advice. If your pain has not improved within this period, or if it worsens, consult your GP. Prolonged use without review is not recommended.

Can I use the Voltarol plaster on my back?

Yes, the plaster is suitable for use on the lower back to relieve localised muscle pain. Make sure the skin is clean, dry, and intact before applying. If your back pain is severe, persistent, or accompanied by other symptoms such as numbness or bladder problems, seek medical advice promptly rather than relying on topical pain relief alone.

Can I wear the Voltarol plaster while exercising or swimming?

The plaster is designed to stay in place during normal daily activities, including light exercise. However, it is not waterproof, so swimming or prolonged exposure to water may cause it to peel away. If the plaster becomes loose or falls off, replace it with a new one and ensure the skin is dry before reapplying.

What are the alternatives to the Voltarol 140mg medicated plaster?

Alternatives include topical diclofenac gels such as Voltarol Emulgel, ibuprofen-based topical gels, or oral NSAIDs if topical treatment is insufficient. For those who cannot use NSAIDs, paracetamol or non-pharmacological approaches such as heat therapy may be appropriate. Our creams and ointments collection includes a range of topical pain relief products to compare.

Does the Voltarol plaster interact with other medicines?

Although topical diclofenac has lower systemic absorption than oral forms, interactions are still possible. Known interactions include anticoagulants such as warfarin, other NSAIDs, lithium, and methotrexate. Always inform your pharmacist or GP of all medicines you are taking — including over-the-counter products — before starting this plaster.

What does the latest research say about topical diclofenac plasters?

Clinical evidence supports the use of topical diclofenac for localised musculoskeletal pain, with studies showing meaningful pain reduction compared to placebo in conditions such as knee osteoarthritis and soft tissue injuries. Topical NSAIDs are generally considered to have a more favourable gastrointestinal safety profile than oral NSAIDs, making them a useful option for patients at higher GI risk. NICE guidelines acknowledge topical NSAIDs as a first-line option for localised joint pain in certain patient groups.

How Should You Use the Voltarol 140mg Medicated Plaster?

Using the plaster correctly is straightforward, but a few simple steps make a real difference to how well it works and how comfortable it feels on your skin. Always read the patient information leaflet supplied with the pack before your first application.

Do not apply the plaster to broken, infected, or irritated skin. Avoid applying it near the eyes, mouth, or mucous membranes. Do not cover the plaster with an airtight dressing or bandage.

What Is the Correct Dose of the Voltarol 140mg Plaster?

The dose is one plaster per application, worn for up to 12 hours. You may use up to two plasters in any 24-hour period, but do not exceed this. The plaster is not suitable for children under 16 years of age.

When Is the Best Time to Use the Voltarol Plaster?

There is no single "best" time of day — apply the plaster when your pain is most troublesome or when you need relief most. Many people find it helpful to apply one plaster in the morning and, if needed, a second in the evening, spacing applications roughly 12 hours apart. Avoid applying the plaster immediately before bed if you are concerned about skin reactions going unnoticed overnight.

If you are using the plaster to manage pain related to physical activity, applying it an hour or so before exercise — provided the skin is clean and dry — may help you stay comfortable during movement.

How Long Can You Use the Voltarol Plaster For?

This plaster is intended for short-term use only. Do not use it continuously for more than 14 days without seeking advice from your GP or pharmacist. If your pain has not improved after a week of regular use, or if it worsens at any point, stop using the plaster and consult a healthcare professional. Prolonged use without medical review is not advisable.

If you find you need pain relief beyond 14 days, your GP can assess the underlying cause and recommend a more appropriate long-term management plan.

Do not exceed the recommended dose. If in doubt, speak to your pharmacist.

What Are the Most Common Side Effects of the Voltarol 140mg Plaster?

Because the Voltarol 140mg Medicated Plaster is applied directly to the skin, the most frequently reported side effects are localised reactions at the application site rather than systemic effects. These are generally mild and resolve once the plaster is removed.

  • Skin redness (erythema) at the application site
  • Itching or pruritus
  • Mild burning or stinging sensation under the plaster
  • Localised skin rash

What Are the Less Common Side Effects of the Voltarol Plaster?

Less commonly, some people experience more pronounced skin reactions or other localised effects. These affect fewer people but are worth being aware of before you start using the plaster.

  • Contact dermatitis — an inflammatory skin reaction that may cause blistering or weeping
  • Dry or flaking skin at the site of application
  • Localised swelling or oedema
  • Photosensitivity — increased sensitivity of the treated skin to sunlight
  • Discolouration of the skin at the application site

If you develop contact dermatitis or a significant skin reaction, remove the plaster and do not reapply. Speak to your pharmacist before using the product again.

What Are the Serious Side Effects of the Voltarol Plaster?

Serious systemic side effects are rare with topical diclofenac because the amount absorbed into the bloodstream is much lower than with oral NSAIDs. However, they can occur, particularly in people who use the plaster over large areas of skin or for extended periods. Stop using the plaster immediately and seek urgent medical attention if you experience any of the following:

  • Signs of a severe allergic reaction — facial swelling, difficulty breathing, widespread hives, or anaphylaxis
  • Severe skin blistering or peeling beyond the application site
  • Symptoms of gastrointestinal bleeding — such as dark or tarry stools, or vomiting blood
  • Significant changes in urine output, which may indicate kidney effects

What Should You Do If You Experience Side Effects?

For mild skin reactions, remove the plaster and allow the skin to recover before deciding whether to reapply. If the reaction is moderate or persistent, speak to your pharmacist — they can advise whether you should continue, switch to an alternative product, or see your GP. You can report suspected side effects directly to the MHRA via the Yellow Card scheme at yellowcard.mhra.gov.uk.

Never ignore a side effect that feels unusual or severe. Your pharmacist is always a good first point of contact for guidance on managing reactions to over-the-counter medicines.

Can the Voltarol Plaster Interact With Other Medicines?

Although topical diclofenac has lower systemic absorption than oral forms, clinically relevant interactions are still possible. Tell your pharmacist or GP about all medicines you are currently taking before using this plaster. Known interactions include anticoagulants such as warfarin (which may have their effect altered), other NSAIDs taken orally or topically, lithium, methotrexate, and certain antihypertensive medicines. Using multiple NSAID-containing products simultaneously increases the risk of side effects and should be avoided.

If you are concerned about any side effects, contact your pharmacist or GP immediately.
