Topical lidocaine/benzalkonium is a combination medication containing both lidocaine (a local anesthetic) and benzalkonium (a disinfectant). The lidocaine helps relieve pain and itching on the skin. It works by temporarily stopping nerve cells from being activated (waking up) and sending pain signals to the brain. The benzalkonium stops germs that can cause infections on the skin.

Double check the age cut-off of your topical lidocaine/benzalkonium product before you use it for your child. Typically, you shouldn't use any kind of topical lidocaine/benzalkonium product in children under 2 years old. But some topical lidocaine/benzalkonium creams can't be used by children under 12 years old. If your child is below the age cut-off for topical lidocaine/benzalkonium products, ask their provider for safer options.
Make sure to clean your injury before applying topical lidocaine/benzalkonium.
Wash your hands with soap and water after using topical lidocaine/benzalkonium. This will help avoid getting it in your eyes or mouth, which can cause irritation and other side effects.
If you're using topical lidocaine/benzalkonium liquid and your provider asked you put a bandage over the area where you applied the medication, make sure to let the medication dry before putting on the sterile bandage.
If you're using topical lidocaine/benzalkonium spray for areas on your face, spray the medication into your hand first and then gently apply it to your face. Don't spray the medication directly on your face. Doing so might cause you to get the medication in your eyes, nose, or mouth and cause irritation.
Ask your provider before using topical lidocaine/benzalkonium if you have deep wounds, animal bites, or serious burns. These types of injuries likely need more immediate medical attention.
It's not recommended to use more than one medication that contains lidocaine at the same time. Doing so can lead to skin irritations or more serious side effects, such as seizure, heart rhythm problems, and coma. Lidocaine can be found in many over-the-counter pain medications that you apply on your skin. These include pain patches, soaps, gels, and creams. Talk with your pharmacist or healthcare provider if you're not sure whether you're using multiple lidocaine products.
Topical lidocaine/benzalkonium can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.

Though this hasn't been reported with topical lidocaine/benzalkonium, prescription-strength lidocaine has been linked to a serious blood problem called methemoglobinemia. This is when your blood can't deliver enough oxygen to your body. To prevent this problem, make sure you don't use more than one medication that contains lidocaine at the same time or use more topical lidocaine/benzalkonium than recommended. Contact your provider right away if you notice any of these symptoms after using topical lidocaine/benzalkonium, such as headaches, dizziness, trouble breathing, fast heart rate, feeling tired, and pale, gray- or blue-colored skin, lips, and nail beds.
