What Is This Medicine?
To put it simply, lidocaine and prilocaine periodontal gel is a prescription medicine used to lower pain in your mouth. Think of it as a liquid or gel version of a numbing shot, but applied directly to the surface. A very well-known brand name for this gel is Oraqix.
When your doctor places this gel on your gums, the area goes numb very quickly. This helps block pain signals before your dental cleaning or procedure begins. Dentists often choose this option to make your visit much easier and more comfortable.
Your dental care team will decide if this numbing gel fits your specific needs. If you have questions about the treatment plan, always ask your dentist or pharmacist for clear answers.
Things to Tell Your Doctor Before Using This Medicine
Before your dental team applies this numbing gel, they need to know your full health background. Sharing this information keeps you safe and prevents unwanted reactions. Make sure to talk openly about any medical conditions you currently manage.
Here are the important details you must share with your doctor:
- G6PD deficiency: This is a blood enzyme condition that can react poorly to certain medicines. Mentioning this helps your doctor choose the safest option.
- Heart conditions: Let your doctor know if you have any heart problems, as numbing medicines can sometimes affect your heart rate.
- Kidney disease: Your kidneys filter waste out of your body. If they do not work well, medicines might stay in your system longer.
- Liver disease: Your liver helps process and break down medicines. Liver problems can change how your body handles this gel.
- Allergies: Tell your doctor if you have ever had a bad reaction to lidocaine, prilocaine, other anesthetics, dyes, preservatives, or foods.
- Pregnancy: If you are pregnant or plan to become pregnant soon, your doctor must know before using any medicine.
- Breastfeeding: Let your medical team know if you are nursing, as some drugs can pass into breast milk.

You will not take this gel home with you or apply it by yourself. Instead, your dentist or a trained dental nurse will apply it directly to your gums right before your procedure starts. They control the exact amount needed for your comfort.
Extra Care When Treating Young Children
Using this numbing gel on young children requires special medical attention and careful dosing. Children have smaller bodies and can react differently to medicines than adults do. Always talk thoroughly with your pediatric dentist if your child needs a numbing gel.
What to Do If Too Much Gets Used (Overdosage)
An accidental overdosage is rare because professionals handle the application in a clinical setting. However, if you ever think someone swallowed too much gel or received an overdose, act right away. Call your local poison control center or go straight to the nearest emergency room (ER) or emergency department right away. In the US, call 911; in the UK, call 999.
Other Medicines That Can Interact With This Gel
When you take one medicine, it can sometimes interact with other drugs, vitamins, or supplements you use. These interactions can change how well the medicine works or increase your risk of side effects. Lidocaine and prilocaine gel can interact with several common substances.
Here are some medicines that can interact with this gel:
- Acetaminophen, a common pain relief medicine.
- Certain antibiotics, such as dapsone, nitrofurantoin, aminosalicylic acid, and sulfasalazine.
- Seizure medicines, including phenobarbital, phenytoin, and valproic acid.
- Chloroquine, often used for malaria treatment.
- Cyclophosphamide, flutamide, hydroxyurea, and ifosfamide.
- Metoclopramide, which helps with nausea.
- Nitroglycerin, used for heart conditions.
- Other local anesthetics like pramoxine or tetracaine.
- Primaquine and quinine.
This list does not cover every possible interaction. Always give your doctor a complete list of everything you take, including prescription drugs, over-the-counter medicines, herbal supplements, and vitamins. Also mention if you smoke, drink alcohol, or use recreational substances.
Things to Watch Out For While Using This Medicine
This gel numbs your mouth so you do not feel pain during your dental work. Because the area feels numb, you must take extra care to protect your mouth from injury. It is very easy to accidentally bite your tongue, lip, or inner cheek while the numbness wears off.
Avoid eating or chewing until the numbness completely fades away to prevent biting accidents. Also, do not drink very hot or very cold liquids while your mouth is numb. Since your gums and tongue cannot sense temperature normally, you could easily burn or injure your mouth without realizing it.
Make sure to keep the gel away from your eyes. If the medicine accidentally gets into your eyes, it can cause irritation, redness, and injury. Rinse your eyes with clean water right away if contact happens.
| Safe Habits | What to Avoid |
|---|---|
| Wait until feeling returns before eating solid foods. | Chewing food while your tongue and gums are still numb. |
| Drink room-temperature water carefully. | Drinking very hot coffee or ice-cold beverages. |
| Let your dentist handle the gel application. | Trying to apply or take home the prescription gel. |
Possible Side Effects
Like all medicines, this numbing gel can cause side effects, though not everyone experiences them. Knowing what to look for helps you get medical help quickly if something feels wrong.
Side Effects That Need Quick Medical Attention
Contact your dental team or doctor right away if you notice any of these serious signs:
- Allergic reactions: Skin rash, itching, hives, or swelling of your face, lips, tongue, or throat.
- Methemoglobinemia symptoms: This rare condition affects how your blood carries oxygen. Signs include severe headache, unusual tiredness, trouble breathing, nausea, fast heartbeat, or blue-colored skin and lips.
- Heart rhythm changes: Feeling like your heart is racing, beating unevenly, feeling dizzy, fainting, or having chest pain and shortness of breath.
Mild Side Effects to Watch
Some mild reactions can happen at the application site. If these symptoms stay for a long time or become very bothersome, talk to your doctor:
- Mild irritation, slight redness, or itching right where the gel was placed on your gums. These feelings usually go away quickly.
When to Call Emergency Services
If you experience severe breathing trouble, sudden swelling of your throat, chest pain, or signs of a severe allergic reaction, call 911 (US/Canada) or 999 (UK) right away or go to the nearest emergency room. You can also report side effects to the FDA at 1-800-FDA-1088.
Where Should This Medicine Be Stored?
Storage is not something you need to worry about as a patient. Because lidocaine and prilocaine periodontal gel is strictly used inside dental clinics and hospitals, dental professionals manage and store the supply safely. You will never need to keep this product in your home medicine cabinet.
