Lidocaine is a local anesthetic commonly used to relieve pain or discomfort caused by skin irritations, such as sunburn, insect bites, or minor cuts. While it is generally considered safe, there are potential side effects that users should be aware of. Some of the common side effects of lidocaine cream include:
- Itching or tingling at the application site
- Temporary redness, stinging, and swelling
- Blistering, crusting, or irritation of the skin
- Unusual drowsiness, tiredness, or weakness
- Shallow breathing
- Allergic reactions, such as hives, rash, or difficulty breathing
Serious side effects are rare but may include symptoms of methemoglobinemia, a condition that reduces the amount of oxygen carried in the blood. These symptoms include pale, gray, or blue-colored skin, headache, rapid heart rate, and shortness of breath
. It's important to consult a healthcare professional before using lidocaine cream, especially if you have a history of allergies, heart disease, liver disease, or any other medical conditions. Additionally, it's essential to follow the recommended dosage and application instructions provided by the healthcare provider or the medication label
. The active ingredient in lidocaine cream is lidocaine hydrochloride, which works as a local anesthetic by stabilizing the neuronal membrane, thereby providing a numbing effect at the application site
