Lidocaine patches deliver numbing medication directly through the skin to the affected area. Lidocaine works by interfering with nerve signals, which helps to reduce pain sensations at the application site. This provides pain relief without widespread systemic effects common with oral medications. Lidocaine patches are available as both over-the-counter (OTC) and prescription options for localized pain.
Understanding Lidocaine Patches for Neck Pain
Lidocaine patches can be applied to the neck for localized pain relief. The medication works by blocking sodium channels on damaged pain fibers directly under the patch, which helps to reduce nerve firing. Less than 5% of the lidocaine is absorbed into the bloodstream, minimizing systemic effects.
These patches are commonly used for localized pain, including muscle strains, stiffness, and nerve-related pain. While some studies suggest topical lidocaine can be helpful for myofascial neck pain, other research indicates it may not be significantly more effective than a placebo for chronic nonspecific neck pain. Its effectiveness can vary depending on the underlying cause.
Lidocaine patches come in different concentrations. Over-the-counter versions typically contain 4% lidocaine, and prescription patches often contain 5%. Some newer prescription formulations, like ZTLido, contain 1.8% lidocaine but are designed for more efficient delivery. The choice of concentration and specific product may depend on the type and severity of pain, as well as individual patient needs.
Safe and Effective Application
Proper application of a lidocaine patch to the neck area is important for both effectiveness and safety. Ensure the skin at the application site is clean, dry, and intact, free from cuts, irritation, or rashes. If hair is present, it should be clipped with scissors rather than shaved to ensure proper adhesion.
Remove the patch from its protective envelope and peel off the release liner. The patch can be cut into smaller pieces if necessary to fit the painful area, but the protective liner should remain in place while cutting. Apply the patch directly over the painful area, ensuring it adheres smoothly to the skin without wrinkles or folds.
Lidocaine patches are worn for a maximum of 12 hours, followed by a 12-hour patch-free interval. Over-the-counter 4% patches may have a shorter wear time, up to 8 hours. After removing a used patch, fold it in half with the sticky sides together and dispose of it safely, out of reach of children and pets. Wash your hands thoroughly with soap and water after handling the patch.
Important Considerations and Warnings
Lidocaine patches carry important considerations and warnings, especially when applied to sensitive areas like the neck. Common side effects include localized skin reactions such as redness, itching, burning, or irritation at the application site. If severe irritation or a burning sensation occurs, the patch should be removed, and a new one should not be applied until the irritation subsides.
Lidocaine patches should never be applied to open wounds, damaged skin, or mucous membranes like the eyes, nose, or mouth. Accidental contact with these areas should be immediately rinsed with water or saline. Individuals with certain pre-existing health conditions, such as severe liver disease or specific heart conditions, should consult a healthcare professional before using lidocaine patches.
Applying external heat sources, such as heating pads or electric blankets, over a lidocaine patch is not recommended, as heat can increase the absorption of lidocaine into the bloodstream, potentially leading to increased side effects or toxicity. Avoid prolonged direct sunlight or hot baths while wearing the patch. Always consult a doctor or pharmacist before use, particularly if pregnant, breastfeeding, or taking other medications, or if neck pain persists or worsens.
