In the event of a suspected lidocaine patch overdose, immediate action is critical. Contact a poison control center or emergency room without delay. If the person has collapsed, had a seizure, has trouble breathing, or cannot be awakened, call 911 or your local emergency services immediately for medical attention.
A lidocaine patch overdose is a serious medical event caused by the body absorbing too much of the medication. Understanding that the primary risks stem from improper application, accidental ingestion, and exceeding the prescribed dose is the key to preventing an emergency.

Recognizing a Potential Overdose
An overdose occurs when the amount of lidocaine entering your bloodstream becomes toxic. Recognizing the signs is the first step in a proper response.
Critical Emergency Signs
The most severe symptoms require an immediate call to emergency services (911). These indicate a significant medical crisis and include:
- Collapse or loss of consciousness
- Seizures
- Difficulty breathing
- Inability to be awakened
Other Warning Signs
Less severe, but still urgent, symptoms can also indicate a toxic reaction. Watch for sudden changes in mental state, such as:
- Confusion
- Agitation
Understanding the Causes of Overdose
Overdose is almost always a result of misuse, not standard application. The risk increases significantly when the patch is not used exactly as directed by a healthcare professional.
Exceeding the Prescribed Dosage
Using more patches than prescribed, or wearing a patch for longer than the recommended time, allows excess lidocaine to be absorbed. If you miss a dose, apply it when you remember, but do not apply a double dose if it is almost time for your next scheduled one.
Accidental Ingestion
A primary danger, especially for children, is the accidental swallowing, chewing, or sucking on a patch. A used patch still contains a large amount of medication that can be fatal if ingested.
Improper Use
The lidocaine patch is for external use only on intact skin. Never apply it to open wounds or damaged skin unless specifically instructed by your doctor. You should also only use the patch for the specific condition for which it was prescribed.
Critical Safety Protocols to Prevent Misuse
Preventing an overdose relies on a foundation of responsible use and storage. Adhering to these protocols protects both the user and others in the household.
Secure Storage is Non-Negotiable
Always keep new and used lidocaine patches well out of the reach and sight of children and pets. This is the single most important step to prevent accidental ingestion.
Follow Medical Guidance Precisely
Adhere strictly to the directions on your prescription label. Never share this medication with others, even if they have similar symptoms.
Communicate with Your Doctors
Inform your doctor or surgeon if you are using lidocaine patches before any surgery or medical procedure, such as an MRI or CT scan. The patch may need to be removed.
Be Mindful of Numbness
The purpose of the patch is to numb the area. Be careful to avoid accidental burns, cuts, or other injuries to the numb skin, as you will not feel them.
Making the Right Choice for Your Safety
Your immediate action should be determined by the situation you are facing.
- If you are witnessing a potential overdose with severe symptoms: Call 911 immediately and do not delay seeking emergency medical help.
- If you suspect too much medication was used but symptoms are mild or absent: Contact the Poison Control Helpline at 1-800-222-1222 for expert guidance.
- If you are a current user seeking to ensure safety: Commit to storing your patches securely, following dosage instructions perfectly, and properly disposing of used patches.
Vigilance and strict adherence to medical advice are your most powerful tools for using a lidocaine patch safely and effectively.
