Lidocaine cream is a topical anesthetic designed to numb specific areas of the skin, offering temporary relief from discomfort. This medication works by blocking nerve signals in the applied region, preventing them from reaching the brain and thereby reducing sensations of pain, itching, or burning. Understanding how to properly use this cream, especially on sensitive areas like the genitals, is essential for both effectiveness and safety.
How Lidocaine Cream is Used on the Genital Area
Lidocaine cream can be used on the genital area for temporary relief of minor pain, itching, or discomfort, such as from hemorrhoids or insect bites. Its numbing effect can also address other minor skin irritations in this sensitive region.
Beyond everyday discomforts, lidocaine cream may be used prior to minor medical or cosmetic procedures to reduce pain. This includes procedures like waxing, injections, or small biopsies, typically under professional guidance. While it provides surface-level relief, its use in these scenarios is for temporary numbing and not for treating underlying conditions.
Guidelines for Safe Application
Applying lidocaine cream safely involves several steps to maximize its effectiveness and minimize risks. Before a full application, perform a patch test on a small, inconspicuous area of skin to check for any adverse reactions. After confirming no irritation, thoroughly wash your hands and gently clean the area of application with mild soap and water, then pat it dry.
Dispense the smallest amount of cream needed to cover the affected area, as excessive application can increase absorption. Gently rub the cream into the skin until it is mostly dissolved or absorbed, but avoid applying it to broken, cut, or irritated skin, as this can lead to greater absorption and potential side effects. The numbing effect typically begins within 25 to 40 minutes and can last for 1 to 2 hours. Always wash your hands thoroughly with soap and water immediately after applying the cream to prevent accidental numbing of your fingers. Store the cream out of reach of children to prevent accidental ingestion.
Understanding Potential Risks
Despite its benefits, lidocaine cream carries potential risks, especially if not used as directed or if applied excessively. Common side effects at the application site can include mild skin irritation, redness, itching, or a temporary burning sensation. These local reactions are usually mild and resolve on their own.
A more serious concern is systemic absorption, where lidocaine enters the bloodstream. This risk increases if the cream is applied to large areas of skin, to broken or damaged skin, or used in amounts greater than recommended. Signs of systemic toxicity can include numbness or tingling around the mouth, lightheadedness, dizziness, blurred vision, or ringing in the ears. More severe symptoms can involve confusion, drowsiness, muscle twitching, seizures, difficulty breathing, irregular heartbeat, or even cardiac arrest.
Allergic reactions to lidocaine are possible. Symptoms of a severe allergic reaction (anaphylaxis) may include hives, difficulty breathing, wheezing, swelling of the face, lips, mouth, tongue, or throat, and a racing heart. Additionally, lidocaine can interact with other medications, increasing the risk of adverse effects. Certain medical conditions, like heart, liver, or kidney problems, can also increase the risk of complications.
When to Consult a Healthcare Professional
It is important to consult a healthcare professional if symptoms persist or worsen despite using lidocaine cream. If the pain or discomfort is severe, does not improve after a short period of use, or if the underlying cause is unknown, medical advice is necessary.
Immediate medical attention is required if any signs of systemic toxicity or a severe allergic reaction occur, such as widespread rash, significant swelling, difficulty breathing, or changes in heart rate or consciousness. Individuals with pre-existing medical conditions, including heart, liver, or kidney issues, or those taking other medications, should consult a doctor or pharmacist before using lidocaine cream. Furthermore, its use on children, pregnant individuals, or those who are breastfeeding should only occur under the guidance of a healthcare provider.
