Alternatives to Lidocaine If You Can't Fill Your Prescription

When lidocaine is unavailable — whether because of the ongoing shortage or because it's not suitable for your situation — there are several alternatives that doctors, dentists, and other providers may recommend. The right alternative depends on why you're using lidocaine in the first place: is it for a topical patch for nerve pain, a dental injection, a surgical procedure, or something else?

This guide explains the main lidocaine alternatives and helps you understand what questions to ask your provider.

Understanding Why Lidocaine Is Used

Lidocaine is an amide-type local anesthetic that blocks voltage-gated sodium channels, preventing pain signal transmission. It's used in two main contexts:

• Topical/outpatient use: Patches and creams for postherpetic neuralgia (shingles nerve pain), OTC relief of minor skin pain, or numbing before procedures.
• Injectable/clinical use: Local anesthesia for surgery, dental procedures, biopsies, and IV cardiac use for ventricular arrhythmias.

Alternatives are different depending on which use case applies to you. Always discuss changes with your prescriber before switching.

Alternative 1: Bupivacaine (Marcaine)

Bupivacaine is the most commonly used alternative to lidocaine for injectable local anesthesia. It's also an amide anesthetic and works the same way — blocking sodium channels — but it has a longer duration of action (4 to 12 hours vs. 30 minutes to 3 hours for lidocaine).

Bupivacaine is ideal for:

• Surgeries requiring prolonged anesthesia (orthopedic, abdominal)
• Epidural anesthesia during labor and delivery
• Postoperative pain management where extended relief is needed

Important caution: Bupivacaine carries a higher risk of cardiac toxicity than lidocaine, so it requires careful dosing and monitoring. It should only be used under clinical supervision.

Alternative 2: Ropivacaine (Naropin)

Ropivacaine emerged as a safer alternative to bupivacaine, and it is also used when lidocaine is unavailable. It has a significantly lower risk of cardiac toxicity than bupivacaine — about 75% greater safety margin — while maintaining a longer duration than lidocaine (4 to 8 hours).

Ropivacaine is often preferred for:

• Obstetric anesthesia — labor epidurals and C-sections
• Patients with cardiovascular concerns where bupivacaine's toxicity is a risk
• Regional nerve blocks where extended analgesia with minimal motor block is desired

Alternative 3: Mepivacaine (Carbocaine, Polocaine)

Mepivacaine is an amide local anesthetic with a rapid onset and intermediate duration (2 to 3 hours). It's particularly common in dental procedures. One of its advantages over lidocaine is a low vasodilatory effect, which means it often doesn't need to be combined with epinephrine.

Mepivacaine is best for:

• Dental procedures (mepivacaine 3% is widely used)
• Minor surgical procedures where intermediate duration is sufficient
• Patients who cannot receive epinephrine (vasoconstrictor)

Alternative 4: Benzocaine (Topical Only)

Benzocaine is an ester-type (not amide) topical local anesthetic available over the counter. It's found in products like Orajel, Hurricaine gel, and various sore throat sprays. It works only on the surface — it cannot be injected.

Benzocaine may substitute for topical lidocaine for minor skin pain, canker sores, minor burns, and teething.

Note: Benzocaine has a higher risk of allergic reactions than amide anesthetics like lidocaine, and the FDA has warned about the risk of methemoglobinemia (especially in children and infants). Use with caution.

Alternative 5: Capsaicin Patches (For Postherpetic Neuralgia)

If you use lidocaine 5% patches (Lidoderm) for postherpetic neuralgia — nerve pain from shingles — capsaicin 8% patch (Qutenza) is a prescription alternative. A clinical trial found that capsaicin 8% patch provided greater pain reduction over 24 weeks compared to lidocaine 5% patch. It works differently, depleting substance P (a pain neurotransmitter) rather than blocking sodium channels.

Other alternatives for postherpetic neuralgia include gabapentin (Neurontin), pregabalin (Lyrica), and tricyclic antidepressants. Talk to your doctor about which is right for your specific situation.

Summary: Which Alternative Is Right for You?

Here's a quick reference:

• Lidocaine shortage affecting injectable supply (surgery/dental): Bupivacaine or mepivacaine (clinical decision)
• Obstetric or high-risk cardiac patient: Ropivacaine is often preferred
• OTC topical pain relief: Benzocaine products (Orajel, Hurricaine) — but not for injection
• Postherpetic neuralgia (shingles pain): Capsaicin 8% patch (Qutenza), gabapentin, or pregabalin

Still Looking for Lidocaine?

Before switching to an alternative, it's worth making sure lidocaine truly isn't available near you. medfinder calls pharmacies in your area to check current stock levels and texts you the results. See all our tips for finding lidocaine near you.
