1. LIDOCAINE PATCH
Lidocaine Patch is a local painkiller which works by stopping nerves from transmitting painful impulses to the brain. It is used for relieving pain associated with shingles. Many people use patches containing lidocaine, fentanyl or similar sleep-inducing based ingredients as a method of pain relief and there is no doubt of the effectiveness of these in reducing pain levels in the majority of people. The patches work on the principle of acupressure point stimulation, which is achieved by applying a small electrical signal generated within the patch itself. These patches are used in pairs, usually one on the point where pain relief is required and the other in a secondary position.
PROCEDURES FOR USAGE OF THE PATCH
- Wash hands before and immediately after using Lidocaine Patch.
- Remove the liner on the patch.
- Apply the patch so that it covers the painful area. If the painful area is larger than the patch, apply the patch over the most painful area (Patches may also be cut into smaller sizes before removing the liner if desired).
- Be sure to discard the unused pieces of cut patches out of the reach of children and away from pets.
- If irritation or burning occurs when one applies the patch, remove it.
- Do not reapply any patches until the irritation stops.
- Patches may be worn for up to 12 hours within a 24-hour period as directed by the doctor. Clothing may be worn over the area where the patch is applied.
- After removing a patch, fold it in half with the sticky sides together.
- Discard the patch out of reach of children and away from pets. Do not apply another patch to the same area of skin for 12 hours.
- If one misses a dose of Lidocaine Patch, use the dose when one remembers.
- Continue to use it as directed by the doctor.
- Lidocaine Patch is for external use only.

2. LIDOCAINE CREAM
Lidocaine cream is an anesthetic. It works by preventing nerves from transmitting painful impulses to the brain. Lidocaine cream is a topical anesthetic indicated for the relief of pruritus, pruritic eczemas, abrasions, minor burns, insect bites, pain, soreness, and discomfort due to pruritus vulvae, hemorrhoids, anal fissures, and similar conditions of the skin and mucous membranes. Lidocaine cream releases lidocaine from a mild acidic vehicle to stabilize the neuronal membrane by inhibiting the ionic fluxes required for initiation and conduction of impulses, thereby effecting local anesthetic action. Lidocaine cream is used for treating pain, itching, soreness, and discomfort of the skin or mucous membranes due to certain conditions such as eczema, scratches, minor burns, insect bites, and hemorrhoids. Before using Lidocaine cream, seek advice from your doctor or pharmacist as some medical conditions may interact with the cream.
- Wash and completely dry the affected area. Apply a thin layer of Lidocaine cream to the affected area. Gently rub the medicine in until it is evenly distributed.
- Wash hands immediately after using Lidocaine Cream, unless the hands are part of the treated area.
- Lidocaine Cream is for external use only.
- Avoid contact with eyes.
- If contact occurs, wash out the eye at once with water or saline and protect it until the numbness is gone. – Do not bandage or wrap the affected area, unless directed by doctor’
- If one misses a dose of Lidocaine Cream, use it as soon as possible.
- If it is almost time for next dose, skip the missed dose and go back to the regular dosing schedule.
- Use caution when applying Lidocaine Cream over large areas.
- Do not use more medicine, apply more often, or use for longer than prescribed (condition will not improve faster, but the risk of side effects may be increased)
3. WHAT IS LIDOCAINE
Lidocaine was discovered in 1946 and went on sale in 1948. Lidocaine, also known as xylocaine and lignocaine, is a medication used to numb tissue in a specific area and to treat ventricular tachycardia. It can also be used for nerve blocks. Lidocaine is a compound that is widely known as a good treatment for back pain relief, sometimes known as Lignocaine. This is a local anesthetic and is also used as an anesthetic for insignificant surgeries and also for dental surgeries. Patients of arthritis have been extensively treated with Lidocaine and have shown positive results with little or no side effects. One more method of administration of Lidocaine is through injections directly into the back. This treatment lasts for just a couple of hours and so is rarely used except in dire emergencies. This treatment is mostly used to confirm a diagnosis and for locating the exact muscle that is causing the problem. The fast acting ingredient is best suited for arriving at a diagnosis and deciding on the treatment for the painful condition.
There are a lot of products on the market with Lidocaine as the main ingredient for pain relief. Many of these products are roll on types and are very effective in treating the symptoms of back pain. With the imminent approval of the FDA for the use of Lidocaine as a pain reliever in cases of arthritis and lower back pain symptoms, people are beginning to gain confidence in the medication that has been engulfed in controversy over the past few years. Lidocaine is not a cure for pain but just a temporary relief from pain while the physicians try to locate the cause of the pain. And until then they can resort to the use of Lidocaine containing applicants to relieve the pain while the treatment continues and a permanent cure is achieved over a period of time. Lidocaine may be absorbed following topical administration to mucous membranes, its rate and extent of absorption depending upon the specific site of application, duration of exposure, concentration and total dosage. In general, the rate of absorption of local anesthetic agents following topical application occurs most rapidly after intratracheal administration. Lidocaine is also well-absorbed from the gastrointestinal tract, but little intact drug appears in the circulation because of biotransformation in the liver. Lidocaine is metabolized rapidly by the liver and metabolites and unchanged drug are excreted by the kidneys. Renal dysfunction does not affect lidocaine kinetics, but may increase the accumulation of metabolites. Factors such as acidosis and the use of CNS stimulants and depressants affect the CNS levels of lidocaine required to produce overt systemic effects. It can cause low blood pressure and an irregular heart rate. There are concerns that injecting it into , joint can cause problems with the cartilage. It appears to be generally safe for use in pregnancy. A lower dose may be required in those with liver problems which is generally safe to use in those allergic to tetracaine orbenzocaine. Lidocaine works by blocking sodium channels and thus decreasing the rate of contractions of the heart. When used locally as a numbing agent, local neurons cannot signal the brain.
4. VISCOUS LIDOCAINE
Lidocaine viscous solution is a local anaesthetic that is applied topically to treat painful mucous membranes or throat pain associated with oral diseases and for procedures involving the mouth or throat. Lidocaine provides pain relief by inhibiting the influx of sodium ions involved in the initiation and conduction of nerve impulses associated with the perception of pain. Lidocaine is a local amide anesthetic that is thought to reversibly block nerve conduction and thereby provide local pain relief. It is not recommended for treating teething pain in children. Viscous lidocaine is used to relieve pain and discomfort from a sore throat/mouth. It is also used to numb the lining of the mouth and throat before certain medical/dental procedures (such as dental impressions). This numbing helps prevent the urge to close the throat, which might make the procedure more difficult. This medication may also be used to relieve pain and discomfort from irritation of the esophagus. Mild nausea, stinging, or burning may occur. If any of these effects last or get worse, contact the doctor or pharmacist promptly. This medication may cause very serious side effects if one is using too much of it. Stop using this medication and get medical help right away if experiencing serious side effects, including: dizziness, drowsiness, slow/shallow breathing, irregular heartbeat, mental/mood changes such as confusion, nervousness, shaking, seizures, vision changes, ringing in the ear, fainting.
5. LIDOCAINE HYDROCHLORIDE
Lidocaine Hydrochloride Jelly USP, 2% is indicated for prevention and control of pain in procedures involving the male and female urethra for topical treatment of painful urethritis, and as an anesthetic lubricant for endotracheal intubation (oral and nasal). This medication is used on the skin to stop itching and pain from certain skin conditions (e.g., scrapes, minor burns, eczema, insect bites and to treat minor discomfort and itching caused by hermorrhoids and certain other problems of the genital/anal area (e.g. anal fissures, itching around the vagina). Some forms of this medication are also used to decrease discomfort or pain during certain medical procedures/exams such as sigmoidoscopy, cystoscopy). Lidocaine is a local anesthetic that works by causing temporary numbness/loss of feeling in the skin and mucous membranes.
Before use on the skin, clean medication to the affected area and dry the affected area as directed. Apply a thin layer of of skin, usually 2 to 3 times a day or as directed.
