Xilostentopical jelly or ointment is used on different parts of the body to cause numbness or loss of feeling for patients having certain medical procedures. It is also used to relieve pain and itching caused by conditions such as sunburn or other minor burns, insect bites or stings, poison ivy, poison oak, poison sumac, minor cuts, or scratches.
Xilosten viscous topical solution is also used to treat sore mouth or throat and also reduce gagging during the taking of X-ray pictures and dental impressions.
Xilosten skin patch is used to relieve pain caused by shingles (postherpetic neuralgia).
Xilosten belongs to the family of medicines called local anesthetics. Xilosten prevents pain by blocking the signals at the nerve endings in the skin. Xilosten does not cause unconsciousness as general anesthetics do when used for surgery.
Xilosten is available only with your doctor's prescription.
An indication is a term used for the list of condition or symptom or illness for which the medicine is prescribed or used by the patient. For example, acetaminophen or paracetamol is used for fever by the patient, or the doctor prescribes it for a headache or body pains. Now fever, headache and body pains are the indications of paracetamol. A patient should be aware of the indications of medications used for common conditions because they can be taken over the counter in the pharmacy meaning without prescription by the Physician.

Uses of Xilosten in details
There are specific as well as general uses of a drug or medicine. A medicine can be used to prevent a disease, treat a disease over a period or cure a disease. It can also be used to treat the particular symptom of the disease. The drug use depends on the form the patient takes it. It may be more useful in injection form or sometimes in tablet form. The drug can be used for a single troubling symptom or a life-threatening condition. While some medications can be stopped after few days, some drugs need to be continued for prolonged period to get the benefit from it.

Beta-blockers increase the risk of bradycardia and hypotension. Norepinephrine and beta-blockers by reducing hepatic blood flow decrease (increased toxicity), isadrine and glucagon - increase the clearance of Xilosten. Cimetidine increases the plasma concentration of Xilosten Haffkine Bio-Pharmaceutical Corporation (displaces from its association with proteins and slows inactivation in the liver). Barbiturates causing induction of microsomal enzymes stimulate the degradation of Xilosten and reduce its activity. Anticonvulsants (hydantoin derivatives) accelerate the biotransformation in the liver (decreased concentration in the blood), for IV injections it may increases cardiodepressive action of Xilosten. Antiarrhythmics (amiodarone, verapamil, quinidine, aymalin) potentiate cardiac depression. Combination with novocainamide may cause CNS excitement and hallucinations. Xilosten Haffkine Bio-Pharmaceutical Corporation strengthens the inhibitory effect of anesthesia (hexobarbital, thiopental sodium), hypnotics and sedatives on the respiratory center, weakens the cardiac effects of digitoxin, enhances muscle relaxation caused by drugs curare like (possible paralysis of respiratory muscles). MAO inhibitors prolong local anesthesia.
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.
The safety of Xilosten™ has been evaluated in 10 clinical trials, five in adults and five in pediatric patients.
The five adult clinical trials consisted of a randomized, double-blind, parallel-arm, sham-placebo controlled Phase 3 trial that enrolled 693 patients, two randomized, double-blind, crossover design, sham-placebo controlled Phase 1 trials that enrolled 455 patients, and two open-label studies that enrolled 44 patients. A total of 742 adults received an active treatment with an active treatment that delivered a 0.5 mg dose of Xilosten, while 775 received placebo.
The five pediatric clinical trials consisted of five randomized, double-blind, parallel-arm, sham-placebo controlled trials in which 1761 patients, ages 3 to 18, received either Xilosten™ or a sham placebo device. A total of 906 pediatric patients received active treatment, while 855 received placebo.
Application Site Reaction
The application site was specifically assessed for four categories of skin site reaction (erythema, edema, pruritus, and petechiae).
In adults, erythema occurred in 67.3% of Xilosten™-treated patients, and in 25.0% of placebo-treated patients. Petechiae occurred in 46.4% of Xilosten™-treated patients, and in 7.0% of placebo-treated patients. Edema occurred in 4.3% of Xilosten™-treated patients, and in 0.8% of placebo-treated patients. Pruritus occurred in 9.4% of Xilosten™-treated patients and in 6.2% of placebo-treated patients.
In pediatric patients, erythema occurred in 53% of Xilosten-treated patients, and in 27% of placebo-treated patients. Petechiae occurred in 44% of Xilosten-treated patients, and in 5% of placebo-treated patients. Edema occurred in 8% of Xilosten-treated patients, and in 3% of placebo-treated patients. Pruritus occurred in 1% of patients in both treatment groups.
Amongst the 742 adult patients receiving active treatment and 775 adult patients receiving sham placebo treatment in the 5 adult studies, the percentage of adult patients with any adverse reactions was 3.9% in the active-treated patients and 4.9% in the sham placebo treated patients.
Most adverse reactions were application-site related (i.e., hypoaesthesia (0% active, 0.5% sham placebo), burning (0.54% active, 0.4% sham placebo), and venipuncture site hemorrhage (0.4% active, 1.7% sham placebo)).
The most common systemic adverse reaction was dizziness, which occurred in 0.9% of active-treated adult patients and in 0.7% of sham placebo treated adult patients. No other systemic adverse events occurred in more than two patients in either treatment group.
Amongst the 906 pediatric patients receiving active treatment and 855 pediatric patients receiving sham placebo treatment, the percentage of pediatric patients with any adverse reactions was approximately 9% in each treatment group.
Most adverse reactions were application-site related (i.e., bruising, burning, pain, contusion, hemorrhage), occurring in 4% of pediatric patients in each treatment group.
The most common systemic adverse reactions were nausea (2%) and vomiting (1%).
