Who Should Not Use Topical Lidocaine?

Lidocaine topical cream is a common medicine cabinet staple, but it should be used cautiously. The chemical is toxic to children and can cause serious side effects. Signs of toxicity include drowsiness, shallow breathing, and weakness. In some cases, seizures can result. The FDA has recommended that children should not be exposed to lidocaine.

People with liver or kidney problems:

Lidocaine is a local anesthetic used to numb areas of the body. Its effect lasts about 30 minutes to three hours. The drug is metabolized primarily in the liver, which is metabolized to monoethylglycine, an inactive compound with a longer half-life. For this reason, people with liver or kidney problems should avoid topical lidocaine application.

People with diabetes:

While there are no studies on the long-term effects of topical lidocaine for diabetes, some patients may be able to find relief from painful diabetic neuropathy with this medicine. Those with diabetes should discuss this topical preparation with their doctors before participating.

People with a history of hepatitis:

People with hepatitis C and HIV should not use lidocaine topical ointments or gels. They can cause damage to the liver. Other medications for hepatitis C include Mavyret, a drug that treats chronic liver disease. If you are concerned about your health, see your doctor.

People with methemoglobinemia:

Methemoglobinemia is a rare but life-threatening condition characterized by an increase in the number of oxidized hemoglobin in the blood. It is thought to be a hereditary condition. It is also known to occur in people who use topical anesthetics. Few studies have examined the incidence of methemoglobinemia in the general population and its associated risk factors. However, a retrospective study of patients with methemoglobinemia in a large referral center identified a population at high risk.

People with severe skin irritations:

People with severe skin irritations should not use topical lidocaine products. Lidocaine topical solutions are available as foams, ointments, and gels. You should follow the manufacturer’s instructions to ensure proper use. Topical lidocaine is best applied to clean, dry skin. Do not apply lidocaine to open wounds, rashes, or the rectum. Before applying lidocaine, always wash your skin thoroughly.

People with a history of convulsions:

The drug can cause skin reactions, such as rashes, blisters, burning, and skin color changes. It can also cause pain and itching. It is best not to use it if you have an open wound or broken skin. You should also tell your doctor if you are suffering from infections or allergic reactions. You should also tell your doctor if you experience numbness or stinging in the affected area.
