A topical that is stronger than lidocaine is one with more than just lidocaine. When lidocaine is combined with benzocaine and tetracaine, it provides stronger anesthesia.

Lidocaine cream works quite quickly. Most people will start to feel a numbing effect within 30 to 60 minutes.

Sensory complaints may include tinnitus and blurred vision. Excitatory signs, such as restlessness, agitation, nervousness, or paranoia, may progress to muscle twitches and seizures. Ultimately, with large overdoses, CNS depression, including unconsciousness and coma, can occur.

Commercially available lidocaine creams that are sold over-the-counter generally are made in strengths between 2-5%. A compounding pharmacy can make creams with higher percentages including a 10% lidocaine cream. These higher-strength numbing creams are available only with a prescription.

Pain relief as a result of benzocaine may last for 15 minutes, whereas lidocaine provides effective relief for 35 to 40 minutes. In a clinical study that evaluated the effectiveness of 5% lidocaine and 20% benzocaine for topical numbing, both were found to be equally effective and may provide relief from pain.

The minimum effective volume of lidocaine 2% with epinephrine required to achieve a complete median nerve block in 95% of patients (MEAV95) calculated using the biased coin up-and-down design was 4 ml [25th–75th percentiles: 3.5–4.0] (Fig. 4).

Lidocaine toxicity is not only determined by the total dose (usually 4.5 mg/kg) but also by the rate of absorption, which is dependent on the blood flow of that tissue.

Perineural injection of 15 ml of lidocaine 0.93% w/v under the US guidance could provide a successful femoral nerve block in 90% of patients.

It is normal for the patient to complain of some pressure or discomfort within the finger during injection. The optimal volume of 1% lidocaine in terms of rapidity of onset, completeness, and duration appears to be 3 ml, based on a study of healthy volunteer subjects.
