Lidocaine cream is a topical medication used to alleviate pain and discomfort on the skin. It functions as a local anesthetic, providing a numbing effect where applied. This cream is available in various strengths, purchased over-the-counter or with a prescription. It offers targeted relief from a range of skin-related sensations.
Understanding Lidocaine Cream
Lidocaine is a local anesthetic that temporarily blocks nerve signals where applied. When absorbed into the skin, it prevents pain sensations from reaching the brain, resulting in a numbing effect. This provides localized pain relief without causing unconsciousness, unlike general anesthetics. The cream is for topical use only, meaning it should only be applied to the skin’s surface.
The numbing effect of lidocaine cream typically begins within 30 to 60 minutes after application. Optimal numbing is often achieved in about 35 to 40 minutes, and the effect can last for several hours. This allows for targeted pain relief directly at the site of discomfort, offering an advantage over oral pain medications that affect the entire body.
Common Applications and Conditions
Lidocaine cream is widely used for temporary relief from minor pain, itching, and discomfort arising from various skin irritations. This includes conditions such as sunburn, insect bites, minor cuts, scrapes, and burns. Its numbing properties help soothe the affected area.
The cream also provides relief for pain and discomfort associated with hemorrhoids and other anorectal conditions. Lidocaine works by numbing the nerves in the affected area, reducing the burning, itching, and pain that hemorrhoids can cause. Some formulations for hemorrhoids contain higher concentrations for more potent relief.
Lidocaine cream is frequently used to numb the skin before minor medical procedures. These include injections, blood draws, IV insertions, and minor skin procedures. Applying the cream beforehand can significantly reduce the pain experienced during these interventions.
Cosmetic procedures also benefit from the numbing effects of lidocaine cream. It is applied to the skin before procedures such as waxing, tattooing, piercing, and laser hair removal to minimize discomfort. This allows individuals to undergo these procedures with reduced pain.
Safe Use and Important Considerations
When using lidocaine cream, follow the product’s instructions carefully for safe and effective application. Apply a thin layer to clean, dry skin. Unless directed by a healthcare professional, do not cover the treated area with bandages, as this can increase absorption.
Adhere to dosage and frequency recommendations on the product label or from a healthcare provider. Exceeding these can lead to increased absorption into the bloodstream, potentially causing systemic effects. For children, a doctor should determine the dose based on body weight.
Common, mild side effects at the application site may include temporary redness, swelling, irritation, or a burning sensation. If these become uncomfortable or persist, remove the cream and consult a doctor. Serious side effects are rare but can occur if too much lidocaine is absorbed into the body.
Signs of excessive systemic absorption include dizziness, blurred vision, ringing in the ears, confusion, or an irregular heartbeat. If any of these serious symptoms appear, seek immediate medical attention. Avoid applying lidocaine cream to large areas of skin, broken or irritated skin, or sensitive areas like the eyes, mouth, or inside the nose, unless directed by a doctor.
Consult a doctor or pharmacist if you are a child, pregnant, breastfeeding, or have underlying health conditions, as specific guidance may be required. Store lidocaine cream in a closed container at room temperature, away from heat, moisture, and direct light, and out of reach of children. Freezing the cream can degrade its effectiveness.
