Voltaren: A Popular Pain Relief Drug

If you’ve ever had aching knees, stiff shoulders, or sore hands from arthritis, chances are someone has recommended Voltaren. But what exactly is it, how does it work, and is it safe? Let’s break it down in plain English.

What is Voltaren?

Voltaren is the brand name for diclofenac, a type of non-steroidal anti-inflammatory drug (NSAID). It works by blocking chemicals in the body called prostaglandins, which are responsible for pain, swelling, and inflammation.

Unlike ibuprofen, which is usually taken as a pill, Voltaren is often used as a topical gel that you rub directly onto sore joints or muscles. This allows the medicine to target the problem area with less impact on the rest of your body.

That said, Voltaren isn’t just available as a gel—it also comes in tablets, patches, sprays, and even injections in some countries. Doctors may prescribe these forms when stronger or more widespread pain relief is needed.

Common Brand Names for Diclofenac

Diclofenac is sold worldwide under many brand names, not just Voltaren. Here are some you might come across:

• US & Global Brands: Cambia (migraine powder), Zipsor (liquid capsule), Flector (patch), Pennsaid (topical solution).

• International Brands: Cataflam (Europe, Asia, Latin America), Voltarol (UK), Diclac (Germany, Canada), Difene (Ireland), Abitren (Europe), Valenac (India), Acoflam (South Africa).

Knowing these names is helpful, especially if you’re traveling or looking for Voltaren in another country.

Forms of Voltaren

Voltaren comes in several forms, depending on the type and severity of pain:

• Topical Gel/Cream/Spray – Best for localized pain, such as arthritis in a knee or hand.

• Tablets/Capsules – Used when pain is more widespread or topical options aren’t strong enough.

• Injections – Administered in hospitals for rapid relief of severe or acute pain.

• Powder (Cambia) – A fast-acting option specifically designed for migraines.

What is Voltaren Gel Used For?

The gel version of Voltaren is especially popular because it works right where you apply it:

• Osteoarthritis: Helps reduce stiffness and pain in joints such as the hands, knees, or elbows.

• Muscle aches and sports injuries: Useful for sore calves, aching shoulders, or recovery after workouts.

• Back or neck strain: Provides relief for pulled muscles or stiff necks.

• Minor sprains or overuse injuries: Ideal for wrist pain from typing or a mild ankle twist.

Because the gel acts locally, it reduces pain without the whole-body side effects you’d get from oral painkillers.

How to Use Voltaren Gel

To get the best results:

• Apply a small amount (pea to grape-sized, depending on the area) and rub it in gently.

• Wash your hands afterward — unless you’re treating your hands. In that case, wait at least an hour before washing.

• Use up to 4 times a day, but never exceed the recommended dose. Extra applications won’t work faster and may increase side effects.

• Avoid heat pads or tight bandages, which can increase absorption in unsafe ways.

Tips for Getting the Best Results

For maximum benefit, apply Voltaren to clean, dry skin — after a shower is ideal. Massage it in gently and avoid covering the area with tight bandages or wraps.

Try to avoid direct sunlight on the treated skin, as it can sometimes cause irritation. And always remember to wash your hands thoroughly after applying (unless treating your hands). This prevents accidental transfer into your eyes, mouth, or other sensitive areas.

Who Shouldn’t Use Voltaren?

While Voltaren is safe for many, it’s not for everyone.

• Children under 12 should generally avoid it unless a doctor recommends otherwise.

• People with allergies to aspirin or other NSAIDs should steer clear.

• Those with heart disease, kidney disease, or liver problems should be cautious, as NSAIDs can put stress on these organs.

• Pregnant women, especially in later months, should avoid Voltaren unless specifically advised by a doctor.

Possible Side Effects

Most people tolerate Voltaren well, but like any medication, it can cause side effects.

• Mild side effects: redness, itching, or slight rash where the gel is applied. These usually fade on their own.

• Systemic effects (rare with gel): stomach upset or discomfort, similar to oral NSAIDs, if used excessively or over large areas.

• Serious reactions (very rare): swelling, difficulty breathing, or severe skin reactions. If these occur, stop using and seek medical help immediately.

Voltaren Gel vs. Tablets

One of the biggest questions people ask is whether to use the gel or tablets.

• Voltaren Gel: Best for targeting specific pain points (like knees or hands). Since less of the drug enters your bloodstream, it usually has fewer risks for your stomach, kidneys, or heart.

• Voltaren Tablets: More effective for widespread pain and inflammation but carry higher risks of stomach ulcers, heart problems, and kidney strain — especially with long-term use.

Most people start with the gel for everyday pain because it’s simpler and safer. Tablets are usually reserved for more severe or systemic pain, under a doctor’s guidance.

Is Voltaren Safe?

Gel (Topical)

For most people, yes. The gel is considered safer than tablets since it’s applied locally. Still, follow precautions:

• Don’t apply to broken or irritated skin.

• Don’t combine with other NSAIDs unless approved by your doctor.

• If you have stomach ulcers, kidney issues, heart disease, or take blood thinners, consult your doctor first.

• Not usually recommended in pregnancy, especially the third trimester.

Tablets (Oral)

While effective, tablets carry higher risks:

• Can cause stomach upset, heartburn, ulcers, or bleeding.

• May strain the kidneys.

• Linked to a higher risk of heart attack or stroke, especially at high doses or long-term use.

• Not safe during pregnancy after 20 weeks, as it can harm the baby’s kidneys or heart.

General rule: Always use the lowest effective dose for the shortest possible time.

Key Takeaways

• Voltaren gel and tablets are not interchangeable — they’re designed for different kinds of pain.

• The gel is often preferred for localized joint or muscle pain because it limits whole-body side effects.

• Stick to the dosing instructions: up to 4 times daily for the gel, and doctor-directed dosing for tablets.

FAQs About Voltaren

1. Can I use Voltaren every day?
Yes, you can. Voltaren gel is safe for daily use, but it’s best to follow the package instructions or your doctor’s advice. Many people use it for flare-ups of pain rather than continuously for months. If you need it long-term, check with your healthcare provider.

2. How long does it take to work?
Some relief may be felt within a few days, but for osteoarthritis, it may take up to a week of consistent use. Stick with it for the full benefit.

3. Can I use it with heat or ice packs?
Ice packs are usually fine, but wait 10–15 minutes after applying the gel before using them. Avoid heat pads, as heat can increase absorption and raise the risk of side effects.

4. Is Voltaren stronger than ibuprofen?
Not exactly — both are NSAIDs, but they work differently depending on dose and form. Voltaren gel has the advantage of targeting pain locally, while ibuprofen is systemic.

5. Can I use Voltaren if I’m already taking pain tablets?
It depends. If you’re using other NSAIDs (like ibuprofen, naproxen, or diclofenac tablets), you shouldn’t combine them without your doctor’s advice, as it can increase risks. But paracetamol (acetaminophen) is usually safe to use alongside Voltaren gel.

6. Is Voltaren safe for seniors?
Yes, and many older adults use it safely. The gel version is particularly useful as it avoids many of the risks associated with NSAID tablets.

7. Can I use Voltaren on any part of the body?
It works best on joints like knees, hands, and elbows. It doesn’t penetrate deep enough for hip or spine pain. Never apply on broken or infected skin.

8. Do I need a prescription for Voltaren?
In many countries, low-strength gel (1%) is available over the counter. Stronger gels and oral tablets usually require a prescription in most countries.

9. Can I use Voltaren on my back or neck?
Yes, Voltaren gel can be applied to muscles and joints in the back or neck if the pain is from strain or overuse. Just avoid sensitive areas like the spine directly or broken skin.

10. Is Voltaren safe for long-term use?
Voltaren is meant for short-term relief. If your pain lasts more than a couple of weeks, it’s best to check in with your doctor to make sure there isn’t a bigger issue that needs attention.

Bottom Line

Voltaren can be a real game-changer for managing achy joints, sore muscles, and arthritis pain. It’s easy to use, works right where you need it, and can help reduce pain without always relying on pills.

Like any medication, though, it’s important to use it wisely. Always follow instructions, avoid combining it with other NSAIDs without medical advice, and talk to your doctor if you have ongoing pain or health conditions.

Used correctly, Voltaren can make moving through your day a whole lot easier.
