Is Voltarol 1.16% Gel the Right Diclofenac Gel for Back Pain?

 

Back pain is one of the most common reasons people visit their GP in the UK — and for many, a targeted topical treatment is exactly what they need. Voltarol Back & Muscle Pain Relief 1.16% Gel with No Mess Applicator is an over-the-counter topical NSAID containing diclofenac diethylammonium. It's designed to deliver localised anti-inflammatory relief directly to the site of pain, without the need to swallow tablets. If you're looking for a diclofenac gel for back pain that's easy to apply and clinically established, this is one of the most widely recognised options available in UK pharmacies. You can explore our full range of pain relief products if you'd like to compare alternatives.

The 100g tube comes with a no mess applicator — a practical feature that means you can apply the gel without getting it all over your hands. That matters more than it sounds, especially if you're applying it to your lower back or a hard-to-reach area. It's a small design detail that makes a real difference in day-to-day use.

 

How Does Voltarol Back & Muscle Pain Relief Gel Work?

 

Diclofenac belongs to the non-steroidal anti-inflammatory drug (NSAID) class. When applied to the skin, it penetrates through to the underlying soft tissue, where it inhibits the enzyme cyclo-oxygenase (COX). This reduces the production of prostaglandins — the chemical messengers responsible for triggering inflammation, swelling, and pain. The key advantage of a topical formulation is that it acts locally, meaning lower systemic absorption compared to oral NSAIDs.

  • Diclofenac inhibits COX-1 and COX-2 enzymes at the site of application
  • Prostaglandin synthesis is reduced, dampening the inflammatory response
  • Pain signals to the nervous system are diminished
  • Localised action means reduced risk of gastrointestinal side effects compared to oral NSAIDs

 

Who Should Use Voltarol Back & Muscle Pain Relief Gel?

 

This gel is suitable for adults and adolescents aged 14 and over who are experiencing localised musculoskeletal pain. It's particularly useful for people who prefer not to take oral pain relief, or who have a history of stomach sensitivity to tablets. That said, it's not appropriate for everyone — always read the label carefully.

  • Adults with acute lower back pain or muscle strain
  • People with sports-related soft tissue injuries
  • Those who want targeted relief without systemic medication
  • Individuals who find oral NSAIDs cause stomach discomfort

Is Voltarol Gel Suitable for Long-Term Use and How Should It Be Stored?

 

Voltarol Back & Muscle Pain Relief Gel is intended for short-term use only. The NHS advises that topical NSAIDs should generally not be used for more than 14 days without medical review. If your pain persists beyond two weeks, or if it worsens at any point, you should speak to your GP or pharmacist rather than continuing to self-treat. Chronic or recurring back pain may need further investigation. You can also browse our creams and ointments collection for other topical treatment options.

Store the gel below 25°C, away from direct heat and sunlight. Keep the cap tightly closed when not in use, and always keep it out of reach of children. Do not use after the expiry date printed on the tube.

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.

What Is Voltarol Back & Muscle Pain Relief 1.16% Gel and What Is It Used For?

 

Voltarol Back & Muscle Pain Relief 1.16% Gel is a topical anti-inflammatory medicine containing diclofenac diethylammonium. It is used to relieve pain and reduce inflammation in muscles, tendons, and joints. Common uses include lower back pain, muscle strains, sprains, and soft tissue injuries resulting from physical activity or everyday movement. It works locally at the site of application, making it a practical choice for people who want targeted relief without taking oral medication.

 

What Do You Need to Know Before Using Voltarol Back & Muscle Pain Relief Gel?

 

Before using this gel, it's important to check whether it is appropriate for you. Do not use it if any of the following apply:

  • You are allergic to diclofenac, aspirin, ibuprofen, or any other NSAID
  • You are in the third trimester of pregnancy (28 weeks or beyond)
  • You have a history of asthma triggered by NSAIDs
  • The skin in the area to be treated is broken, infected, or inflamed
  • You are under 14 years of age
  • You are applying it near the eyes, mouth, or mucous membranes

Speak to your pharmacist or GP before using this gel if you are pregnant (first or second trimester), breastfeeding, or have kidney, liver, or heart conditions. The following medicines may interact with diclofenac gel, particularly if you are also taking them orally:

  • Other oral NSAIDs (e.g. ibuprofen, naproxen) — increased risk of systemic NSAID effects
  • Anticoagulants such as warfarin — monitor closely
  • Ciclosporin or tacrolimus — potential for increased nephrotoxicity
  • Lithium — diclofenac may increase plasma lithium levels

 

How Should You Use Voltarol Back & Muscle Pain Relief Gel?

 

Always use this gel exactly as described in the patient information leaflet or as directed by your pharmacist. Using more than the recommended amount will not speed up relief and may increase the risk of side effects.

  1. Remove the cap and attach the no mess applicator to the tube
  2. Apply a thin layer of gel to the painful area
  3. Gently rub the gel into the skin until absorbed
  4. Wash your hands after application, unless the hands are the treated area
  5. Allow the gel to dry before covering with clothing or a dressing
  6. Do not apply under occlusive dressings or bandages
Indication Age Group Dose Frequency
Back pain, muscle strain Adults & adolescents (14+) 2–4g per application (approx. 2–4cm strip) 3–4 times daily
Soft tissue injury Adults & adolescents (14+) 2–4g per application 3–4 times daily
Children under 14 Not applicable Not recommended Not recommended

 

What Are the Possible Side Effects of Voltarol Back & Muscle Pain Relief Gel?

 

Like all medicines, this gel can cause side effects, although not everyone experiences them. Most side effects are localised to the skin at the application site. If you're also browsing our first aid range, you'll find products that can help manage minor skin reactions.

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

  • Skin redness at the application site
  • Itching or a burning sensation on the skin
  • Dry or flaking skin where the gel is applied
  • Mild rash

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

  • Dermatitis (skin inflammation)
  • Eczema-like skin reaction
  • Blistering or peeling of the skin
  • Photosensitivity (increased sensitivity to sunlight at the treated area)

Stop using the gel and seek medical advice immediately if you develop signs of a serious allergic reaction, such as swelling of the face, lips, or throat, difficulty breathing, or widespread skin reactions.

 

How Should You Store Voltarol Back & Muscle Pain Relief Gel?

 

Correct storage helps maintain the gel's effectiveness and safety throughout its shelf life. Follow these guidelines:

  • Store below 25°C — do not refrigerate or freeze
  • Keep away from direct sunlight and heat sources
  • Always replace the cap tightly after use
  • Keep out of the reach and sight of children
  • Do not use after the expiry date printed on the tube or carton
  • Do not dispose of medicines via wastewater or household waste — return unused medicine to your pharmacist

If you have any questions about storage or whether your gel is still safe to use, your pharmacist will be happy to advise. You can also find further guidance on managing musculoskeletal pain through our pain relief collection.

How does diclofenac gel for back pain actually work in the body?

Diclofenac is a non-steroidal anti-inflammatory drug (NSAID) that inhibits the COX-1 and COX-2 enzymes responsible for producing prostaglandins — the chemicals that drive inflammation and pain. When applied topically, it penetrates the skin and reaches the underlying soft tissue, reducing localised inflammation without the same level of systemic absorption as oral NSAIDs. This makes it a practical option for people who want targeted relief with a lower risk of gastrointestinal side effects.

How do I use Voltarol Back & Muscle Pain Relief Gel step by step?

Attach the no mess applicator to the tube, then apply a thin layer of gel — roughly a 2–4cm strip — to the painful area. Gently rub it in until absorbed, then wash your hands unless the hands themselves are being treated. Repeat up to 3–4 times daily, and avoid applying under tight bandages or occlusive dressings.

How often should I apply Voltarol 1.16% Gel each day?

The recommended frequency is 3 to 4 times daily, spaced evenly throughout the day. Try to apply it at consistent intervals — for example, morning, midday, late afternoon, and evening — to maintain a steady level of anti-inflammatory activity at the site of pain. Do not apply more than 4 times in any 24-hour period.

What are the side effects of Voltarol Back & Muscle Pain Relief Gel?

The most common side effects are localised skin reactions at the application site, including redness, itching, a mild burning sensation, or dry skin. Less commonly, some people experience dermatitis, eczema-like reactions, or increased sensitivity to sunlight on the treated area. If you develop any signs of a serious allergic reaction — such as facial swelling, difficulty breathing, or widespread skin changes — stop using the gel immediately and seek urgent medical attention.

Who should not use Voltarol Back & Muscle Pain Relief Gel?

This gel is not suitable for people who are allergic to diclofenac or any other NSAID, including aspirin or ibuprofen. It should not be used during the third trimester of pregnancy, on broken or infected skin, or by anyone under 14 years of age. People with NSAID-induced asthma should also avoid it — speak to your GP or pharmacist if you are unsure.

Can I use Voltarol gel if I am pregnant or breastfeeding?

Voltarol gel should not be used during the third trimester of pregnancy (28 weeks onwards) due to potential risks to the unborn baby. During the first and second trimesters, use only if advised by a doctor. If you are breastfeeding, seek medical advice before using this gel, as small amounts of diclofenac may pass into breast milk.

What is the difference between Voltarol gel and ibuprofen gel?

Both are topical NSAIDs, but they contain different active ingredients — Voltarol uses diclofenac diethylammonium 1.16%, while ibuprofen gels typically contain ibuprofen 5%. Clinical studies suggest diclofenac gel may have a longer duration of action at the tissue level for musculoskeletal pain, and the no mess applicator in the Voltarol 100g version adds a practical convenience advantage. Your pharmacist can help you decide which is more appropriate for your specific situation.

How long can I use Voltarol Back & Muscle Gel for?

Voltarol Back & Muscle Pain Relief Gel is intended for short-term use only — do not use it for more than 14 consecutive days without consulting a doctor or pharmacist. If your pain has not improved after two weeks, or if it worsens at any point, you should seek medical advice rather than continuing to self-treat. Persistent or recurring back pain may require further investigation.

Can I use Voltarol gel alongside other pain relief medicines?

You can generally use Voltarol gel alongside paracetamol, as these work through different mechanisms. However, combining it with other oral NSAIDs such as ibuprofen or naproxen is not recommended, as this increases the risk of systemic NSAID side effects. Always tell your pharmacist about all medicines you are currently taking before starting a new treatment.

What happens if I accidentally apply too much Voltarol gel?

Applying more gel than recommended is unlikely to cause serious harm, but it may increase the risk of local skin irritation or, in rare cases, slightly higher systemic absorption of diclofenac. If you accidentally ingest any gel or experience unusual symptoms after applying a large amount, contact NHS 111 or your nearest pharmacist for advice. Do not apply more than the recommended dose going forward.

Is Voltarol Back & Muscle Gel suitable for sports injuries?

Yes — Voltarol 1.16% Gel is commonly used for soft tissue sports injuries including muscle strains, sprains, and tendon pain. It is suitable for adults and adolescents aged 14 and over. For broader sports recovery support, you might also want to explore our first aid range, which includes supports and dressings for injury management.

What are the alternatives to Voltarol Back & Muscle Pain Relief Gel?

Alternatives include other topical NSAIDs such as ibuprofen gel (e.g. Ibuleve or Phorpain), as well as topical preparations containing ketoprofen or piroxicam — though some of these require a prescription. Oral pain relief options such as paracetamol or ibuprofen tablets are also available. Speak to your pharmacist to find the most suitable option for your type and severity of pain.

What does the latest research say about diclofenac gel for back pain?

Clinical evidence supports the use of topical diclofenac for localised musculoskeletal pain, with studies showing meaningful reductions in pain scores compared to placebo. The NHS and NICE recognise topical NSAIDs as a first-line option for localised pain, particularly in older adults where oral NSAIDs carry a higher risk of gastrointestinal and cardiovascular side effects. Research continues to support the benefit-to-risk profile of topical diclofenac for short-term use in back and muscle pain.

Does Voltarol gel stain clothing or leave a residue?

Voltarol Back & Muscle Pain Relief Gel is a clear gel that is generally absorbed into the skin without leaving a significant residue, though it is advisable to allow it to dry fully before dressing. The no mess applicator helps minimise transfer to hands and clothing during application. If any gel does contact fabric, rinse with cold water promptly.

How Should You Use Voltarol Back & Muscle Pain Relief 1.16% Gel?

Using Voltarol Back & Muscle Pain Relief Gel correctly makes a real difference to how well it works. Always apply it to clean, dry, intact skin — never to broken, infected, or inflamed areas. Follow these steps each time you apply:

What Is the Correct Dose of Voltarol Back & Muscle Pain Relief 1.16% Gel?

The correct dose depends on the size of the area being treated. As a general guide, a strip of gel measuring 2–4cm is sufficient for most localised areas such as the lower back or a single muscle group. Do not apply more than 4 times in any 24-hour period, and do not treat more than two body areas simultaneously without medical advice.

When Is the Best Time to Use Voltarol Back & Muscle Pain Relief 1.16% Gel?

There is no single "best" time — the key is consistency. Spacing your applications evenly throughout the day helps maintain a steady anti-inflammatory effect at the site of pain. A practical routine might be morning, midday, late afternoon, and before bed, though you should adjust this to fit your daily schedule. Applying the gel before physical activity or after a warm shower, when skin is clean and circulation is increased, may help absorption.

How Long Can You Use Voltarol Back & Muscle Pain Relief 1.16% Gel For?

This gel is intended for short-term use only. Do not use it for more than 14 consecutive days without speaking to a doctor or pharmacist. If your symptoms have not improved within two weeks, or if they worsen at any point during treatment, stop using the gel and seek medical advice — persistent pain may need further assessment. Long-term or repeated use without medical supervision is not recommended.

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

What Are the Most Common Side Effects of Voltarol Back & Muscle Pain Relief 1.16% Gel?

Most people who use Voltarol Back & Muscle Pain Relief Gel tolerate it well, and side effects are generally mild and localised to the skin at the application site. Because the gel works topically rather than systemically, the risk of whole-body side effects is considerably lower than with oral NSAIDs.

  • Skin redness at the application site
  • Itching or a mild burning sensation on the skin
  • Dry or flaking skin where the gel has been applied
  • Mild rash

What Are the Less Common Side Effects of Voltarol Back & Muscle Pain Relief Gel?

Less commonly, some people experience more pronounced skin reactions. These are still generally localised but may require you to stop using the gel and seek advice from your pharmacist or GP.

  • Contact dermatitis (skin inflammation caused by the gel)
  • Eczema-like skin reaction
  • Blistering or peeling of the skin at the application site
  • Photosensitivity — increased sensitivity to sunlight on the treated area
  • Localised swelling or oedema

What Are the Serious Side Effects of Voltarol Back & Muscle Pain Relief Gel?

Serious side effects are rare with topical diclofenac, but they can occur. Systemic absorption is low, but in some individuals — particularly those using the gel over large areas or for extended periods — there is a small risk of NSAID-related systemic effects. Stop using the gel immediately and seek urgent medical attention if you experience any of the following:

  • Signs of a severe allergic reaction: swelling of the face, lips, tongue, or throat
  • Difficulty breathing or wheezing
  • Widespread skin rash, hives, or blistering beyond the application site
  • Chest pain or tightness

What Should You Do If You Experience Side Effects of Voltarol Gel?

For mild skin reactions such as redness or itching, you may be able to continue using the gel at a reduced frequency — but speak to your pharmacist first. If the reaction is more severe, stop using the gel and allow the skin to recover. Do not apply the gel to the same area if a skin reaction has occurred there. You can report suspected side effects directly to the MHRA via the Yellow Card scheme at yellowcard.mhra.gov.uk.

Can Voltarol Back & Muscle Pain Relief Gel Interact With Other Medicines?

Although topical diclofenac has lower systemic absorption than oral forms, interactions are still possible — particularly if you are taking other medicines that affect the same pathways. The most clinically relevant interactions include:

  • Oral NSAIDs (e.g. ibuprofen, naproxen) — combined use increases the risk of systemic NSAID effects including gastrointestinal irritation
  • Anticoagulants such as warfarin — diclofenac may affect bleeding time; monitor closely
  • Lithium — topical diclofenac may increase plasma lithium concentrations
  • Ciclosporin or tacrolimus — potential for increased nephrotoxicity

Always tell your pharmacist or GP about all medicines, supplements, and herbal remedies you are taking before starting Voltarol gel.

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