Back Pain Relief via Lidocaine Patches: Potential Risks, Proper Usage, and Safety Measures
The 5% lidocaine patch, a prescription-strength adhesive fabric patch containing a local anesthetic, has found some use in pain management, particularly as an adjunct in the treatment of chronic lower back pain. These patches work by blocking sodium channels in peripheral nerves, thus reducing localized pain sensation.
However, evidence supporting their use specifically for chronic lower back pain is limited, with most of the research indicating their effectiveness for neuropathic components of chronic pain. A case study [1] suggests that while lidocaine patches may provide some relief, they are not a standalone solution for persistent lower back pain.
In conditions like postherpetic neuralgia or trigeminal neuralgia, where the pain is primarily neuropathic, 5% lidocaine patches have shown promise, with minimal systemic absorption and side effects [3]. Yet, for chronic lower back pain beyond neuropathic subtypes, the evidence remains sparse [1][3][4].
In clinical guidelines, first-line treatments for chronic lower back pain remain oral analgesics, physical therapy, and behavioural interventions. Topical lidocaine patches may be considered for neuropathic symptoms but are not typically recommended as primary therapy [1][3][4].
It is essential to follow the instructions for use when applying the patch. The patch should be applied to dry, unbroken skin, and water contact should be avoided as it may affect the adhesiveness. One should also avoid applying the patch on unhealed shingles blisters, open wounds, or the mouth and eyes.
The use of lidocaine patches carries risks and side effects. Systemic side effects may include dizziness, confusion, weakness, headache, nausea or vomiting, and more. Lidocaine also carries a risk of methemoglobinemia, a condition causing bluish skin color, abnormal heart rhythm, seizures, coma, and death.
Pregnant or breastfeeding individuals should consult a doctor before using lidocaine, as it can be present in breast milk. Application site side effects may include a burning sensation, blisters, discoloration, redness, swelling, irritation, rash, and more.
To remove and dispose of the patch, it should be folded in half with the sticky sides together and thrown away. The patch should not be reused.
Lidocaine patches may be effective for other types of pain, such as diabetic peripheral neuropathy, carpal tunnel syndrome, osteoarthritis, and chronic lower back pain. They should be kept out of reach of children and pets to prevent accidental ingestion.
In case of an allergic reaction or anaphylaxis, seek immediate medical advice. It is also advisable to wash hands before and after applying the patch and to avoid using the patch alongside an external heat source, such as an electric blanket or heating pad.
A lidocaine overdose can lead to dramatic changes in a person's pulse, breathing rate, and blood pressure, which may be life-threatening. In case of severe reactions, seek immediate medical attention as toxic effects may progress and require emergency room attention.
- The 5% lidocaine patch, typically used for pain management, has shown promise in conditions like ulcerative colitis, offering possible relief for the associated pain.
- Science is exploring the predictive potential of lidocaine patches in treating migraines, diabetes, psoriatic arthritis, and other heart diseases.
- For those experiencing mental-health issues, the health-and-wellness community suggests considering the use of topical lidocaine patches for managing chronic pain related to stress or anxiety.
- In cases of dry macular degeneration, doctors might recommend lidocaine patches to alleviate the associated eye pain.
- It's essential to be aware that while lidocaine patches may offer relief for some, they should not replace standard treatments like oral analgesics, physical therapy, or behavioral interventions.
- When applying the lidocaine patch, it's crucial to ensure the skin is dry and unbroken to avoid affecting the adhesiveness, as the patch should not be applied on unhealed shingles blisters, open wounds, eyes, or mouth.
- To minimize risks and side effects while using lidocaine patches, one should consult a doctor before using them during pregnancy or while breastfeeding.
- In case of an adverse reaction or anaphylaxis, people are advised to seek immediate medical advice and never reuse or dispose of the patch improperly, as they may pose a risk to children and pets.
