When your mouth is sore from a canker sore, a burned tongue, or a denture that won’t sit right, you want fast, reliable relief. That’s where choline salicylate and lignocaine comes in. This combination isn’t just another over-the-counter gel-it’s a targeted treatment designed to numb pain and reduce swelling in the mouth and throat. But knowing how to use it properly, what it actually does, and what risks to watch for can mean the difference between quick comfort and avoidable side effects.
What Exactly Is Choline Salicylate and Lignocaine?
This isn’t one single chemical. It’s a two-part formula:
- Choline salicylate is a non-steroidal anti-inflammatory drug (NSAID). It works by blocking enzymes that cause pain and swelling, similar to aspirin but with a different chemical structure.
- Lignocaine (also called lidocaine) is a local anesthetic. It stops nerve signals in the area where it’s applied, so you don’t feel pain-even if the sore is still there.
Together, they deliver both pain relief and inflammation reduction in one application. You’ll find this combo in gels, sprays, and oral solutions sold under brand names like Orabase, Topex, and generic versions in pharmacies across Australia, the UK, and parts of Europe.
It’s not meant for swallowing. It’s for topical use only-applied directly to the inside of the mouth, gums, or throat. The gel sticks to the sore spot, delivering medicine where it’s needed most.
When Is It Used?
This medication is most commonly used for:
- Mouth ulcers (canker sores)
- Denture irritation or sores
- Minor burns from hot food or drinks
- Sore throats from viral infections like colds or flu
- Teething discomfort in children over 12 months (only under medical advice)
- Post-dental procedure pain, like after a tooth extraction
It’s not for cold sores caused by herpes simplex virus. Those need antiviral treatments, not anti-inflammatories. It’s also not a cure-it’s a temporary shield against pain while your body heals.
Many people reach for it when other remedies fail. If ibuprofen or paracetamol isn’t touching the pain, and your mouth feels raw, this gel often makes the difference between eating normally and avoiding food altogether.
How to Use It Correctly
Using this wrong can make things worse-or even dangerous.
- Wash your hands before and after use.
- Use a clean finger or cotton swab to apply a small pea-sized amount directly to the sore.
- Don’t rub it in. Just gently press it onto the affected area.
- Avoid eating or drinking for at least 30 minutes after application. Let it sit.
- Use no more than four times a day. Never exceed the recommended dose.
- Do not use for more than seven days without checking with a pharmacist or doctor.
For children, always follow age-specific instructions. In Australia, products containing choline salicylate are not recommended for children under 12 due to the risk of Reye’s syndrome-a rare but serious condition linked to salicylates in kids with viral infections.
Even if you’re an adult, don’t assume it’s harmless. Swallowing large amounts can lead to salicylate toxicity, which causes ringing in the ears, nausea, confusion, and rapid breathing.
Side Effects and Warnings
Most people tolerate this combo well. But side effects happen.
Common side effects:
- Mild stinging or burning right after application (usually fades in seconds)
- Temporary numbness beyond the sore area
- Change in taste
Less common but serious risks:
- Allergic reaction: rash, swelling of lips or tongue, difficulty breathing
- Overuse leading to methemoglobinemia (a blood condition that reduces oxygen delivery-rare but possible with excessive lignocaine use)
- Salicylate poisoning: dizziness, vomiting, fast breathing, ringing in ears (especially if you swallow the gel or use too much)
If you’re allergic to aspirin or other NSAIDs, you’re likely allergic to choline salicylate too. Check your history. If you’ve ever had asthma flare-ups after taking ibuprofen or aspirin, skip this product.
People with kidney or liver disease should use it cautiously. Your body clears these drugs through the liver and kidneys. If those organs are impaired, the medicine can build up.
Also, avoid using this if you’re pregnant or breastfeeding unless your doctor says it’s safe. While topical use means very little enters the bloodstream, there’s not enough data to call it completely risk-free.
What’s the Difference Between Choline Salicylate and Aspirin?
Many assume choline salicylate is just aspirin in disguise. It’s not.
Aspirin is acetylsalicylic acid. Choline salicylate is a salt form of salicylic acid combined with choline-a compound naturally found in the body that helps with nerve signaling and liver function.
Why does this matter? Because choline salicylate is less likely to irritate the stomach lining than aspirin. That’s why it’s preferred for oral use-it’s designed to be gentle on the digestive tract while still delivering anti-inflammatory power.
But here’s the catch: both still carry the same risks for children. That’s why you’ll see warnings on the packaging: “Do not use in children under 12.” It’s not a marketing tactic-it’s a safety rule backed by decades of medical data.
Can You Use It With Other Medications?
Yes-but carefully.
If you’re already taking:
- Other NSAIDs (ibuprofen, naproxen)
- Blood thinners like warfarin
- Diuretics or ACE inhibitors for high blood pressure
- Antidepressants like SSRIs
you could be at higher risk of side effects. Even though this is applied topically, a small amount still gets absorbed. Mixing it with oral NSAIDs increases your total salicylate load. That can lead to bleeding risks or kidney stress.
Always tell your pharmacist what else you’re taking-even if you think it’s unrelated. They’ll check for hidden interactions.
Also, avoid alcohol while using this. It can increase the risk of stomach irritation and make side effects like dizziness worse.
Alternatives If This Doesn’t Work or Isn’t Safe
Not everyone can use choline salicylate and lignocaine. Here are safer or equally effective alternatives:
| Option | How It Works | Best For | Limitations |
|---|---|---|---|
| Choline salicylate + lignocaine | Reduces inflammation + numbs pain | Ulcers, denture sores, burns | Not for children under 12; avoid if allergic to aspirin |
| Benzydamine mouthwash | Anti-inflammatory, no anesthetic | Sore throat, radiation-induced mouth sores | Can taste bitter; not for swallowing |
| Topical benzocaine gel | Only numbs (no anti-inflammatory) | Quick pain relief for ulcers | Higher risk of methemoglobinemia; avoid in infants |
| Oral paracetamol or ibuprofen | Systemic pain relief | General pain, fever | Slower action; doesn’t target the sore directly |
| Saltwater rinses | Reduces bacteria, soothes tissue | Mild sores, prevention | No numbing effect; takes longer to help |
For children, saltwater rinses or cold foods like ice pops are often the safest first step. For adults with chronic mouth sores, a prescription steroid rinse might be more effective long-term.
What to Do If It Doesn’t Help
If you’ve used this product for five days and your sore hasn’t improved-or if it’s getting bigger, bleeding, or turning white-you need to see a dentist or doctor.
Persistent mouth ulcers can be a sign of:
- Vitamin B12 or iron deficiency
- Autoimmune conditions like lichen planus
- Oral cancer (especially if it’s painless and doesn’t heal)
Don’t keep reapplying the gel hoping it’ll work. That delays diagnosis. A simple check-up can rule out something more serious.
Storage and Handling Tips
Keep the tube or bottle tightly closed. Store it at room temperature-below 25°C. Don’t leave it in the car or bathroom where heat and moisture can break it down.
Check the expiration date. Old gel loses its effectiveness. If it looks grainy, smells odd, or has changed color, throw it out.
Keep it out of reach of children. Even a small amount swallowed accidentally can be dangerous.
Frequently Asked Questions
Can I use choline salicylate and lignocaine while pregnant?
It’s generally not recommended unless a doctor says it’s necessary. While very little of the medicine enters the bloodstream when used topically, there isn’t enough research to confirm it’s completely safe during pregnancy. If you have a severe mouth sore, your doctor may suggest safer alternatives like saltwater rinses or topical benzocaine in limited doses.
Is this the same as Orajel?
Not exactly. Many Orajel products contain benzocaine and menthol, not choline salicylate. Some Orajel versions do include salicylates, but most over-the-counter ones in Australia and the US use benzocaine as the main active ingredient. Always check the ingredient list. Choline salicylate is more common in pharmacy brands like Topex or generic versions sold under the name "oral ulcer gel".
Can I use this for a sore throat?
Yes, but only for mild sore throats caused by irritation or minor infections. It’s not a substitute for treating strep throat or other bacterial infections. If your sore throat lasts more than a week, comes with fever, swollen glands, or white patches, see a doctor. You might need antibiotics or further testing.
Why does my mouth feel numb longer than expected?
Lignocaine can sometimes cause prolonged numbness if you apply too much or if the gel spreads to areas like the tongue or inner cheek. This usually wears off in a few hours. If numbness lasts more than 6 hours or spreads to your lips or face, stop using the product and contact a healthcare provider. It could be a sign of overuse or sensitivity.
Can I give this to my 8-year-old for teething?
No. Products containing choline salicylate are not approved for children under 12 due to the risk of Reye’s syndrome, a rare but life-threatening condition linked to salicylates during viral illnesses. For teething, use chilled teething rings, gentle gum massage, or paracetamol drops if recommended by a pediatrician.
Final Thoughts
Choline salicylate and lignocaine is a useful tool for managing oral pain-but it’s not a magic fix. Used right, it can help you eat, speak, and sleep without discomfort. Used wrong, it can cause harm. Always read the label. Stick to the dose. Watch for signs of trouble. And if something doesn’t improve, don’t guess-get it checked.
For most people, this gel is a quiet hero in the medicine cabinet. It doesn’t make headlines. But for someone with a mouth full of sores, it’s the difference between suffering and relief.

It's wild how we treat oral pain like it's not a window into systemic health. That gel? It's just masking what your body's trying to tell you. If you're getting recurrent ulcers, it's not about the gel-it's about your gut, your iron, your stress levels. We fix symptoms instead of asking why they're there.
And yet, here we are, reaching for the tube like it's a spiritual remedy. Funny how medicine became a quick fix for existential discomfort.
