Lidocaine, pronounced LYE-doe-kane, is a local or topical anesthetic that can be applied to the skin or to mucous membranes to reduce the immediate feeling of pain and produce numbness. Lidocaine has been in the market since 1948, and is available over the counter, which means no doctor prescription is needed to buy it or use it. Lidocaine is used for a variety of medical conditions, and is often one of the drugs included in first-aid kits in the form of a combination antibiotic/pain relieving cream. Sprays for treating sunburn, insect bites, or poison ivy often include lidocaine as the main ingredient. Lidocaine gel is often used in dental procedures as a way of numbing the area before applying an injection, or to reduce pain after the procedure is finished.
Lidocaine works by halting the pain signal transmitted by the nerve endings on the skin. When used to the affected area, a feeling of numbness follows after 20-30 seconds; depending on the strength of the drug, the effect may last from 30 minutes to several hours. Lidocaine is not intended for internal use, so it should be applied carefully in mucous membranes. For example, using a cotton swab is the best way to apply just the right amount to numb the feeling of pain on a tooth or in an area in the gums. For larger areas, a dentist may prescribe lidocaine oral cavity patches, which can be left on for hours without need for a reapplication or change.
Because of possibilities of high dosage of overdosing, you cannot buy full strength injectable Lidocaine over the counter. It is a powerful anesthetic and also used for cardiac purposes.

Tell your prescriber or health care professional about all other medicines you are taking, including non-prescription medicines, nutritional supplements, or herbal products. Also tell your prescriber or health care professional if you are a frequent user of drinks with caffeine or alcohol, if you smoke, or if you use illegal drugs. These may affect the way your medicine works. Check with your health care professional before stopping or starting any of your medicines.
Here is another explanation for this, an over-the-counter medication (OTC) can generally be purchased from the pharmacy without a prescription. One often assumes because there is no requirement for direct physician supervision, the medication is safe. While many items purchased OTC started as prescription items, there is no guarantee they are safe, especially when used in combination with other medications and in people who may have compromised kidney function. Drugs can interact with each other regardless of whether or not a prescription is required.
Many drugs are eliminated by the kidneys, and when kidney function worsens, toxic drug metabolites may accumulate. Likewise, drug elimination often involves liver enzymes in the Cytochrome P450 family (often called CYP). When drugs share the same CYP enzyme system (isoform) for their elimination toxins may accumulate, and some may cause serious heart disturbances known as arrhythmias. Click here for a list of well-referenced medications grouped by CYP liver enzyme isoform. Since patients with kidney disease often have secondary illnesses, such as diabetes or hypertension, they are on several medications, making a drug interaction more likely.
Many people now order medications online or buy them at a supermarket, but for those purchasing OTCs from the local pharmacy, asking the pharmacist is a simple matter. Although Internet resources are easily accessible, the physician is the best resource. Each patient should consult the physician when contemplating the use of OTC medications, regardless of where purchased.
