When you’re dealing with muscle pain, joint stiffness, or swelling from an injury, Emulgel with diclofenac can feel like a lifesaver. It’s one of the most common topical pain relievers sold in Australia, and for good reason - it works fast, targets the sore spot, and doesn’t hit your stomach like oral pills. But what if it doesn’t work for you? Or maybe you’re worried about side effects, or it’s just too expensive? You’re not alone. Many people switch to alternatives, often without knowing what’s actually out there - or what’s better suited for their situation.
What is Emulgel (Diclofenac)?
Emulgel is a brand-name topical gel containing diclofenac sodium, a nonsteroidal anti-inflammatory drug (NSAID) that reduces pain and inflammation right where you apply it. Each gram of Emulgel delivers 1% diclofenac, meaning 10 mg of the active ingredient per application. It’s absorbed through the skin and works locally, so it doesn’t flood your whole body like a tablet would.
People use it for osteoarthritis in knees or hands, sprains, strains, back pain, and even minor sports injuries. It usually starts working within 30 minutes, and most users feel noticeable relief within a few days. The gel is fragrance-free, non-greasy, and dries quickly - which is why it’s popular among athletes and older adults.
But it’s not perfect. Some users report skin irritation, redness, or itching at the application site. In rare cases, it can cause allergic reactions or even affect liver function with long-term use. And while it’s safer than oral NSAIDs for the stomach, it’s still not recommended for people with severe kidney disease, asthma triggered by NSAIDs, or pregnant women in the third trimester.
Top Alternatives to Emulgel
If Emulgel isn’t doing the job - or you’re looking for something cheaper, gentler, or more effective - here are the most common and clinically supported alternatives available in Australia.
1. Voltaren Emulgel (Diclofenac Diethylamine)
Many people don’t realize that Voltaren Emulgel is essentially the same drug as Emulgel - just a different salt form. Emulgel uses diclofenac sodium, while Voltaren uses diclofenac diethylamine. Both deliver the same amount of diclofenac (1%) and work the same way. The difference? Voltaren’s formula is slightly more lipophilic, meaning it penetrates the skin a bit faster. Some users report quicker relief with Voltaren, especially for deep joint pain. But in head-to-head studies, the pain reduction after one week is nearly identical. The real difference? Price. Voltaren is often cheaper, especially with a PBS subsidy.
2. Nurofen Gel (Ibuprofen 5%)
Nurofen Gel contains ibuprofen at a 5% concentration - five times stronger than the diclofenac in Emulgel by weight. But here’s the catch: ibuprofen is less potent per milligram than diclofenac. So even though there’s more of it, it doesn’t always mean better results. Studies show diclofenac gels reduce pain 15-20% more than ibuprofen gels over a 2-week period. That said, Nurofen Gel is a solid choice if you’re sensitive to diclofenac or need something you can use more frequently. It’s also approved for children over 12, which Emulgel isn’t.
3. Biofreeze (Menthol 3.5%)
Biofreeze is a cooling gel that doesn’t contain any NSAIDs. Instead, it uses menthol - the same compound found in peppermint oil - to trigger cold receptors in your skin. This creates a numbing effect that distracts your brain from pain signals. It’s not anti-inflammatory, so it won’t reduce swelling. But if your pain is sharp, sudden, or nerve-related (like tennis elbow or shin splints), Biofreeze can feel amazing. Many physiotherapists in Sydney recommend it for pre-stretching or post-workout soreness. It’s safe for daily use, doesn’t interact with other meds, and has almost no side effects.
4. Aspercreme (Trolamine Salicylate 10%)
Aspercreme contains trolamine salicylate, a derivative of aspirin. It works similarly to NSAIDs by blocking pain chemicals locally, but without the same risk of stomach irritation. It’s often used for arthritis and back pain. The gel has a slight odor and can feel sticky, but it’s effective for moderate pain. One study from the University of Melbourne found it reduced pain by 40% in osteoarthritis patients after 7 days - slightly less than diclofenac, but still significant. It’s a good option if you’re allergic to NSAIDs or want something OTC without diclofenac.
5. Capsaicin Cream (0.025%-0.075%)
Capsaicin cream comes from chili peppers and works by depleting substance P - the chemical your nerves use to send pain signals. It’s not a quick fix. You’ll likely feel a burning sensation at first, which fades after a few days of use. But after 2-4 weeks, many users report lasting pain reduction, especially for chronic conditions like osteoarthritis. A 2024 meta-analysis in the Australian Journal of Pain Management found capsaicin reduced pain by 33% compared to placebo - slightly better than ibuprofen gel, though still behind diclofenac. It’s ideal for people who need long-term, low-dose relief without systemic side effects.

When to Choose What
Choosing the right gel isn’t about which one is “best.” It’s about matching your pain type, lifestyle, and health needs.
- Go for Emulgel or Voltaren if you have inflammation - swelling, redness, warmth in the joint. These are your strongest options for arthritis or tendonitis.
- Try Nurofen Gel if you’re under 18, have mild pain, or want a cheaper option with fewer side effects.
- Use Biofreeze if your pain is sharp, sudden, or you need quick numbing before movement. Great for athletes or desk workers with neck strain.
- Try Aspercreme if you’ve had stomach issues with oral NSAIDs or are allergic to diclofenac.
- Stick with capsaicin if you’ve tried everything else and still have chronic pain. It takes time, but it can change the game for long-term users.
What Not to Do
Many people make simple mistakes that reduce effectiveness - or cause harm.
- Don’t apply heat after using NSAID gels. Heat increases absorption and can lead to skin burns or systemic side effects. Avoid heating pads, hot showers, or saunas for at least 6 hours after application.
- Don’t use more than 4 times a day. Even if the pain is bad, overuse raises your risk of skin damage or liver stress. Stick to the label.
- Don’t combine with oral NSAIDs. Taking diclofenac pills and gel together doubles your risk of kidney problems and internal bleeding. Talk to your pharmacist before mixing.
- Don’t use on broken skin. If you’ve scraped your knee or have a rash, skip the gel. It can sting badly and increase absorption into your bloodstream.
What to Do Instead
Topical gels work best when they’re part of a bigger plan.
- Pair your gel with gentle stretching or physiotherapy. A 10-minute mobility routine after applying Emulgel can double its effect.
- Use ice for the first 48 hours after an injury, then switch to heat or gel. Cold reduces swelling; heat and gel improve circulation.
- Keep a pain diary. Note what you applied, when, and how much relief you got. This helps you spot patterns - and gives your doctor better info.
- Ask your pharmacist about PBS subsidies. Voltaren and Emulgel are often covered if you have a chronic condition like osteoarthritis.
Frequently Asked Questions
Can I use Emulgel and Biofreeze together?
Yes - but not at the same time. Use Biofreeze for immediate relief before activity, then wait 4-6 hours before applying Emulgel for longer-term inflammation control. Never mix them on the same spot. They work differently, and layering them won’t make them stronger - it might irritate your skin.
Is Emulgel better than tablets for joint pain?
For localized pain - like a single sore knee or elbow - yes. Topical diclofenac delivers the drug right where it’s needed, with 90% less in your bloodstream than a tablet. That means fewer side effects like stomach upset, high blood pressure, or kidney strain. But if your pain is widespread - say, both knees and your lower back - oral NSAIDs might be more practical. Always talk to your doctor before switching.
How long can I safely use Emulgel?
For acute injuries (like a sprained ankle), use it for up to 2 weeks. For chronic conditions like osteoarthritis, you can use it daily for months - but only under medical supervision. Long-term use (over 3 months) should include regular liver and kidney checks. If you’re over 65 or have high blood pressure, ask your pharmacist about safer alternatives.
Are there natural alternatives to Emulgel?
Yes - but they’re not as strong. Arnica gel, turmeric cream, and CBD topicals have some evidence for mild pain relief, but none match diclofenac’s effectiveness for inflammation. They’re best for people who can’t use NSAIDs at all - like those with ulcers or allergies. Don’t expect miracles, but they can help as a complement.
Can I use Emulgel if I’m pregnant?
Avoid it in the third trimester. Diclofenac can affect fetal circulation and delay labor. In early pregnancy, it’s considered low-risk for short-term use on small areas, but only if other options like paracetamol or ice don’t help. Always check with your obstetrician before using any topical NSAID during pregnancy.
Final Thoughts
Emulgel is a solid choice for targeted pain relief - but it’s not the only one. The best option depends on your pain type, your body’s response, and your long-term needs. If one gel doesn’t work, don’t give up. Try another. Keep track of what helps. Talk to your pharmacist. Pain isn’t one-size-fits-all, and neither should your treatment be.
I used Emulgel for my knee arthritis last winter and it was a game-changer - until my skin turned red and itchy like I’d been rubbed with sandpaper. Switched to Biofreeze and now I can actually walk without wincing. No burning, no irritation, just instant cool relief. Also way cheaper at Walmart.
PS: Don’t forget to ice first, then gel. That’s the secret sauce.
My mom’s been using capsaicin cream for her hands for six months now. At first she swore it was making it worse - burning like hell for a week. But then… poof. The stiffness just melted. She doesn’t even use ibuprofen anymore. It’s not magic, but it’s real.
Just don’t touch your eyes after. Learned that the hard way.
So many people don’t realize Voltaren and Emulgel are basically the same thing. The salt form changes absorption speed, not efficacy. And yes, Voltaren’s cheaper because it’s been around longer and PBS subsidizes it. Also, the gel texture? Voltaren’s less sticky. Minor thing, but when you’re 70 and your hands shake? It matters.
Also - don’t use heat after. I saw a guy in the gym put a heating pad over his Emulgel-covered shoulder. He needed a trip to urgent care. Just… don’t.
Oh wow. So you wrote a 2000-word essay on topical NSAIDs and didn’t mention that Emulgel is literally the same drug as Voltaren? You just buried it in paragraph 3 like it’s a secret? And then you list Biofreeze like it’s a miracle cure when it does nothing for inflammation? Come on.
People aren’t stupid. We know menthol is just a distraction. If you’re going to write a comparison, compare the science - not the marketing.
Just wanted to say thank you for this. I’ve been dealing with chronic elbow pain for years and tried everything. Capsaicin was the one that finally worked - even though I cried the first week. I kept a pain diary like you said and realized I only needed it twice a week after month two. Also, my pharmacist helped me get Voltaren on PBS - saved me $80 a month. You’re right - talk to your pharmacist. They’re the real heroes.
Also, no emojis. Just… thank you.
I used to think gels were just fancy lotion until I tore my rotator cuff lifting a fridge (yes, I know, dumb). Emulgel gave me maybe 30% relief. Biofreeze? Instant. Like someone poured liquid nitrogen on my shoulder. I started using it before every yoga class - it’s my pre-stretch ritual now. And the best part? No weird side effects. No dizziness. No stomach issues. Just cold, clean, sweet relief. I’m not even an athlete. I’m just a person who hates pain.
Also, I now have a Biofreeze tattoo. Not really. But I want to.
Wait - is that weird? I’m sorry.
Why are we even talking about gels? 😅
What if the real solution is… not using your body like a meat robot? Like, maybe stop doing 100 burpees before coffee? Or maybe your desk chair is a torture device? I’m not saying gels are useless - I use them too - but maybe the real fix is not ignoring your body until it screams.
Just saying. 🤷♂️
My dad’s a retired mechanic and swears by Aspercreme. Says it’s the only thing that doesn’t make his skin feel like it’s on fire. He’s got a bad back and can’t take pills anymore. He uses it with a warm towel - not a heating pad, just a damp towel warmed in the dryer. Works great. Also, he says it smells like old pharmacies. Nostalgic.
Also, he writes his pain diary on a napkin. It’s adorable.
Emulgel and Voltaren are identical in effect. Only difference is brand and price. Use Voltaren. Save money. Same results. Capsaicin works for chronic pain but takes time. Biofreeze is for temporary relief. Done.
Let me tell you something about modern medicine - we’ve lost touch with the wisdom of our ancestors. Back in my village in India, we used crushed neem leaves and turmeric paste. No chemicals. No side effects. Just pure nature. Now we pay $25 for a tube of synthetic jelly and call it science. The real pain? Not your knee. It’s your dependence on corporate pharmaceuticals.
Try Ayurveda. Your body will thank you. 🙏
Thank you for the thorough and well-researched overview. I appreciate the clinical distinctions between the formulations and the emphasis on contraindications. Many online resources lack this level of precision. The advice regarding heat application and concurrent NSAID use is particularly valuable. I will be sharing this with my patients.
One additional note: For elderly patients with renal impairment, topical diclofenac still carries systemic absorption risk. Monitoring creatinine levels remains prudent even with topical use.
Guys. Stop using gels like they’re magic. If you’ve been using the same one for 3 months and it’s not working, it’s time to see a physio or get an MRI. Pain isn’t a puzzle you solve with more cream. It’s a warning sign. Stop treating symptoms and start treating the cause.
I’ve seen too many people burn their skin trying to ‘get more relief.’ You’re not a lab rat. Stop it.
OMG I JUST REALIZED I’VE BEEN USING EMULGEL WRONG THIS WHOLE TIME 😭
I’ve been putting it on right after a hot shower and then stretching. That’s why my skin gets so red!! I thought I was just sensitive. Now I’m using it cold, after ice, and waiting 4 hours before I move. My knee feels 100% better. Thank you for the heat warning - I almost missed it.
Also, I spelled ‘diclofenac’ wrong five times in this comment. Sorry.
