Exploring Lidocaine: A Comprehensive Guide to the Local Anesthetic


What is Lidocaine

Lidocaine is something you might encounter when you need to have a medical procedure or deal with pain. It’s a medication that can temporarily numb a specific part of your body. 

When applied correctly, it makes that area feel less pain. 

Doctors and healthcare professionals often use Lidocaine in various forms, like creams, gels, ointments, and injections.

It can help you feel more comfortable when you get a shot, have a minor surgery, or have skin pain or itching. 

Lidocaine is generally safe when used as directed, but it’s important to follow the instructions carefully and not use too much, as improper use can cause side effects. 

Some forms of Lidocaine are available over-the-counter, while others require a doctor’s prescription.

Always use the right type and follow the guidance given to you by your healthcare provider. 

Remember, Lidocaine doesn’t cure the underlying cause of pain or discomfort; it provides temporary relief by numbing the area, which can help you feel better while you heal or undergo a medical procedure.

How to use Lidocaine 

To use Lidocaine as a pain relief treatment, follow these steps:

  • Wash Your Hands: Start by washing your hands with soap and water to ensure they’re clean.
  • Read the Instructions: If you have a lidocaine cream or gel, read the instructions on the packaging carefully. It will tell you how to use it.
  • Prepare the Area: Ensure the area where you apply Lidocaine is clean and dry. If it’s a cut or scrape, clean it gently with mild soap and water, then pat it dry.
  • Apply a Thin Layer: Using your finger or a clean cotton swab, apply a thin layer of Lidocaine to the painful area. Don’t use too much; just a small amount is enough.
  • Rub It In Gently rub the Lidocaine into your skin using a circular motion. Be sure to cover the entire painful area.
  • Wash Your Hands Again: After applying the Lidocaine, wash your hands to remove any residue.
  • Wait for It to Work: Lidocaine takes some time to numb the area. Follow the instructions on the packaging for how long you should wait. It’s usually around 15-30 minutes.
  • Avoid Touching Your Eyes and Mouth: Be careful not to touch your eyes or mouth after applying Lidocaine, as it can also make those areas numb.
  • Wash It Off: When using Lidocaine, gently remove the area with soap and water. Ensure you don’t get soap or water in your eyes using Lidocaine near them.
  • Follow Doctor’s Advice: If a doctor prescribes the Lidocaine or gives you specific instructions, be sure to follow those closely.

How it works

Lidocaine is a helpful medicine that can make painful areas of your body feel better. It does this by getting in the way of the messages that travel from your nerves to your brain. Imagine your nerves as messengers and your brain as the receiver of these messages.

When you use Lidocaine on a part of your body, it starts to work on the nerves in that area. It does something clever: it blocks tiny nerve gates that usually let in special particles called sodium ions. These sodium ions play a big role in sending pain signals to your brain. When Lidocaine blocks these gates, the sodium ions can’t get through, which means the pain signals don’t travel to your brain either.

This “blocking” action of Lidocaine causes the area where you applied it to feel numb. It’s like pressing a “pause” button on pain. But remember, Lidocaine only affects the area where you put it, not your whole body.

It’s this ability to target a specific spot that makes Lidocaine a useful tool for doctors when they need to help patients feel less pain during procedures.

In summary, lidocaine works by blocking certain “gates” in your nerves, which helps reduce the pain messages traveling to your brain. It’s like a “pause” button for pain, but it only works in the area where you use it.

What should I tell my care team before I take this medication?

Before using a lidocaine cream, having a conversation with your care team is important. Here’s what you should tell them:

  • Medical History: Share your complete medical history, including any allergies, past illnesses, and current health conditions. This information helps your care team assess if lidocaine cream is safe.
  • Current Medications: Inform your care team about all your current medications, supplements, or treatments. Some substances can interact with Lidocaine, potentially causing adverse effects.
  • Allergies: If you have known allergies to any substances, including Lidocaine, ensure your care team is aware. Allergic reactions can be serious, so this information is crucial.
  • Pregnancy or Breastfeeding: If you are pregnant or breastfeeding, discuss this with your care team. They can advise you on the safety of using lidocaine cream during these periods.
  • Skin Conditions: Let your care team know if you have any skin conditions, like rashes or infections. They can guide you on whether using lidocaine cream on your skin is safe.
  • Intended Use: Clearly explain why you want to use the lidocaine cream. Your care team can guide you on whether it’s appropriate for your needs and recommend alternatives if necessary.
  • Dosage and Application: If you’ve received instructions on using the cream, relay this information to your care team. They can confirm whether you are following the recommended guidelines.
  • Any Discomfort or Side Effects: If you’ve experienced discomfort, side effects, or unexpected reactions while using the cream, it’s vital to let your care team know. They can offer advice or make adjustments to your treatment plan if needed.
  • Monitoring: Discuss how you plan to monitor your response to the lidocaine cream. Regular communication with your care team allows them to track your progress and make any necessary adjustments to your treatment.

By sharing this information with your care team, you ensure that they have a comprehensive understanding of your health and can provide you with the best guidance on using lidocaine cream. This open communication helps prioritize your safety and well-being.

How CBD and Lidocaine work together

When CBD and Lidocaine are used together, they can have a complementary effect on pain relief and comfort. Imagine CBD as a gentle helper and Lidocaine as a numbing agent, working hand in hand to make you feel better.

CBD’s Role for You:

CBD, short for cannabidiol, is a compound derived from the cannabis plant. It interacts with your body’s endocannabinoid system, which plays a big role in regulating various bodily functions, including pain perception. 

CBD doesn’t make you feel “high” like another compound in cannabis called THC. Instead, it has anti-inflammatory and calming properties.

CBD is like the calm and soothing friend in this partnership. It helps to reduce inflammation and calm down your nerves, which can be especially helpful if you’re dealing with pain related to inflammation. 

CBD doesn’t make things numb like Lidocaine, but it can reduce the intensity of the pain signals that your nerves send to your brain.

Lidocaine’s Role for You:

Lidocaine, on the other hand, is like the numbing superhero. It blocks the signals of pain from your nerves by interfering with sodium channels. This prevents those pain signals from traveling to your brain, which is why it makes the area where it’s applied feel numb.

When CBD and Lidocaine are used together, you get the benefits of both. 

CBD helps calm down the inflammation and reduce the intensity of pain, while Lidocaine provides that numbing sensation, making the pain even more manageable. It’s like having a dynamic duo on your side, working together to make you more comfortable.

Working together for You:

The combination of CBD and Lidocaine can be especially effective in situations where you have pain that’s related to inflammation and also need temporary relief. CBD’s soothing properties can help prepare the area, while Lidocaine takes care of the numbing action. 

What side effects I may notice

Lidocaine can be a helpful pain relief tool, but like many medications, it may bring some side effects. It’s important to be aware of these potential effects to use it safely and understand what to expect.

1. Skin Irritation: You may notice mild skin irritation, such as redness, itching, or a burning sensation at the application site. This is a common and usually temporary side effect. It’s like a little itch or tickle on your skin.

2. Numbness and Tingling: Lidocaine’s numbing action can sometimes cause you to feel numbness or tingling in the area where it’s applied. It’s like that feeling you get when your foot falls asleep, but it’s usually not as intense.

3. Allergic Reactions: Although rare, some people may experience allergic reactions to Lidocaine, which can include skin rashes, swelling, or difficulty breathing. If you notice these symptoms, it’s essential to seek medical help immediately.

4. Headaches or Dizziness: Lidocaine can sometimes lead to mild headaches or dizziness. It’s like feeling a bit lightheaded, similar to when you stand up too quickly.

5. Changes in Heartbeat: Lidocaine can affect your heart rate. You may notice your heartbeat feels faster or irregular. This is more likely to occur when using Lidocaine in larger amounts or for extended periods.

6. Nausea or Vomiting: Some people may experience mild nausea or even vomiting as a side effect of Lidocaine. It’s like having an upset stomach.

7. Blurred Vision or Double Vision: Rarely, Lidocaine can affect your vision, causing it to become temporarily blurred or doubled. It’s important to avoid activities that require clear vision, like driving, if you experience these effects.

8. Nervousness or Restlessness: Lidocaine can sometimes make you feel nervous or restless. You might find it challenging to relax while using it.

Where should I keep my medication?

Storing Lidocaine safely at home is crucial to maintain its effectiveness and ensure it doesn’t pose any risks.

1. Find the Right Spot: Keep your Lidocaine in a cool and dry place. A cabinet or drawer in a room with a steady temperature is perfect. Avoid spots that get too hot, like near stoves and places with lots of moisture.

2. Secure the Cap: If your Lidocaine comes in a container with a special cap that’s hard for kids to open, be sure to close it tightly. And make sure it’s in a spot where kids can’t reach it. We want to keep it out of their curious hands.

3. Keep It in Its Package: It’s best to keep your Lidocaine in the box or packaging it came in. This helps protect it from light and air, which can make it less effective.

4. No Extreme Temperatures: Don’t leave your Lidocaine where it can get very hot or very cold. Super hot or freezing places can hurt the medication. So, don’t leave it in your car on a scorching day or in a super cold garage.

5. Check the Date: Look at the expiration date on the lidocaine packaging. Using it after that date might not be safe or work as well. If it’s past the date, make sure to get rid of it the right way.

6. Watch Out for Pets: Keep an eye on your pets too. Lidocaine isn’t meant for them and can be harmful if they get to it.

7. Stay Away from Fire: Lidocaine can catch fire, so keep it far from open flames, sparks, or anything that can burn.

8. Dispose of It Properly: If you have some lidocaine left that you’re not going to use, or it’s past the expiration date, make sure to get rid of it the right way. Don’t flush it down the toilet or toss it in the trash. Ask your local pharmacy or healthcare provider for guidance on how to do it safely.

By following these steps for storing Lidocaine at home, you can help make sure it’s safe, works well, and lasts a long time. Always remember to follow any specific storage instructions that come with the product, as they can vary depending on the type of Lidocaine you have

What may interact with this medication?

Before you use Lidocaine, it’s important to know that it can interact with certain things. These interactions can affect how lidocaine works and your safety. Here’s what you need to be aware of:

1. Medications: You should tell your doctor about all the medications you’re taking, whether they are prescription, over-the-counter, or even herbal supplements. Some medications can interact with Lidocaine and cause side effects or reduce its effectiveness.

2. Other Local Anesthetics: Using other local anesthetics or medications that numb your skin, like benzocaine, at the same time as Lidocaine can increase the risk of side effects or make the numbing effect too strong.

3. Heart Medications: If you’re taking heart medications, like antiarrhythmics, you should be cautious. Lidocaine can affect your heart rate, and combining it with certain heart medications might lead to irregular heartbeats or other problems.

4. Anti-seizure Medications: Some anti-seizure drugs, such as phenytoin or mexiletine, can interact with Lidocaine, affecting its effectiveness or leading to increased side effects.

5. Herbal Supplements: Herbal supplements can also interact with Lidocaine. For example, St. John’s Wort may reduce the effectiveness of Lidocaine.

6. Skin Conditions: If you have skin conditions, like eczema or psoriasis, using Lidocaine on affected areas can lead to increased absorption of the medication, potentially causing side effects. Be cautious when using Lidocaine on compromised skin.

7. Allergies: If you’re allergic to any medications, especially anesthetics or Lidocaine itself, it’s crucial to let your doctor know. Allergic reactions can be severe, so your healthcare provider can suggest an alternative if needed.

It’s important to communicate with your healthcare provider about all the medications you’re taking and any health conditions you have before using Lidocaine. This will help ensure your safety and the effectiveness of the medication. Your doctor can guide potential interactions and adjust your treatment plan.
