Topical pain relief options, applied directly to the skin, address localized discomfort without affecting the entire body. These treatments can help manage various aches and pains.
Understanding Lidocaine Patches
Lidocaine patches deliver lidocaine directly through the skin to the affected area. Lidocaine functions as a local anesthetic by temporarily blocking sodium channels in nerve fibers. This inhibits pain signals to the brain, numbing the application site.
These patches are available in various strengths; over-the-counter versions typically contain 4% lidocaine, while prescription patches come in 1.8% and 5% concentrations. They are commonly used for localized pain conditions, including post-herpetic neuralgia (nerve pain after shingles), muscle pain, and other nerve-related discomfort.
Application to the Abdomen
Lidocaine patches can be applied to the abdominal area, but their effectiveness is limited to localized, superficial pain rather than deep, internal discomfort. They may be considered for conditions like muscle strains in the abdominal wall, certain types of nerve entrapment syndromes such as Anterior Cutaneous Nerve Entrapment Syndrome (ACNES), or localized pain from a surgical incision once cleared by a healthcare professional. These patches are intended for pain originating from the skin or tissues just beneath it, not from internal organs.
When applying to the abdomen, ensure the skin is clean, dry, and intact. The patch should not be placed on open wounds, cuts, irritated skin, or areas with rashes or burns. Additionally, areas with excessive hair should be avoided or hair trimmed to ensure proper adhesion and absorption of the medication.
Safe Use and Important Considerations
Most prescription patches are designed to be worn for up to 12 hours within a 24-hour period, followed by a 12-hour patch-free interval. Over-the-counter versions typically have a wear time of 8 to 12 hours. Applying too many patches or wearing them for longer than recommended can increase the absorption of lidocaine into the bloodstream, raising the risk of systemic side effects.
Common side effects at the application site include redness, itching, burning, rashes, or blisters. These reactions are usually mild and temporary. Less common but more serious systemic side effects can include dizziness, lightheadedness, nausea, or confusion. It is important to avoid applying heat sources, such as heating pads or electric blankets, over the patch, as this can also increase lidocaine absorption.
Proper disposal of used patches is important, as they still contain medication. Used patches should be folded in half with the sticky sides together and discarded out of reach of children and pets. Hands should be washed thoroughly after handling the patches. Lidocaine patches are not suitable for individuals with a known allergy to lidocaine or other amide-type local anesthetics, or those with certain heart conditions or severe liver disease.
When to Consult a Healthcare Professional
Consult a healthcare professional if abdominal pain is severe, persistent, or unexplained. Pain that lasts for several hours or days, or pain that worsens over time, warrants medical evaluation. These patches are intended to manage symptoms, not to diagnose or treat the underlying cause of pain.
Immediate medical attention is necessary if abdominal pain is accompanied by symptoms such as fever, vomiting, bloody stools, or difficulty breathing. Any signs of an allergic reaction to the patch, such as hives, facial or throat swelling, or difficulty breathing, require prompt medical care. If the pain feels deep-seated rather than superficial, a doctor can help determine the source of the discomfort and recommend appropriate treatment.
