Lidocaine spray is a local anesthetic that is used to numb the affected area within 5 minutes after application. It is important to note that this product may contain inactive ingredients, which can cause allergic reactions or other problems. Before using lidocaine spray, it is recommended to tell your doctor or pharmacist if you are allergic to it or to other anesthetics such as bupivacaine, prilocaine, or PABA, or if you have any other allergies. It is also important to inform your doctor or pharmacist about your medical history, especially if you have broken skin/infection in the area where lidocaine is to be used, heart disease, liver disease, or a certain blood disorder (methemoglobinemia) .
Some of the common side effects of lidocaine spray include mild nausea, stinging, swelling, or burning. If any of these effects last or get worse, it is recommended to tell your doctor or pharmacist promptly. Serious adverse experiences are generally systemic in nature and may result from high plasma levels caused by excessive dosage, rapid absorption, or inadvertent intravascular injection, or may result from a hypersensitivity, idiosyncrasy, or diminished tolerance on the part of the patient.
It is important to note that an overdose of numbing medicine can cause fatal side effects if too much of the medicine is absorbed through your skin. Therefore, it is not recommended to use large amounts of lidocaine spray or cover treated skin areas with a bandage or plastic wrap without medical advice. If you experience any signs of an allergic reaction such as hives, difficulty breathing, or swelling of your face, lips, tongue, or throat, it is recommended to seek emergency medical help immediately.
