What Is Lidosol-50 (Topical lidocaine)
Lidosol-50 (Topical lidocaine) treats pain. It numbs the area where it is applied, which blocks your nerves from sending pain signals to your brain. It belongs to a group of medications called local anesthetics.
Lidocaine Ointment USP, 5% is indicated for production of anesthesia of accessible mucous membranes of the oropharynx.
It is also useful as an anesthetic lubricant for intubation and for the temporary relief of pain associated with minor burns, including sunburn, abrasions of the skin, and insect bites.

Risks And Warnings For Lidosol-50 (Topical lidocaine)
There are potentially major health risks associated with Lidosol-50 (topical lidocaine). For some groups, this risk might be substantially greater. If this concerns you, discuss other choices with your physician or pharmacist.
Using too much medication
Use Lidosol-50 (topical lidocaine) only as prescribed by your physician. This drug may accumulate in your body if you use it more frequently or at a larger dose than advised. Before applying topical lidocaine to badly injured skin or infected wounds, consult your physician. Your body may absorb large levels of lidocaine as a result of certain circumstances. Serious side effects, including seizures, breathing difficulties, low blood pressure, a slow heartbeat, and abrupt cardiac arrest, can result from taking too much lidocaine. If you have any effects while taking topical lidocaine, seek medical attention immediately.
Blood problem (methemoglobinemia)
Methemoglobinemia, a dangerous blood condition when your red blood cells are unable to supply your body with enough oxygen, can be brought on by Lidosol-50 (lidocaine 5% ointment). If you have low G6PD, a genetic disorder that causes your red blood cells to rupture or fragment, your risk is increased. Use caution while applying topical lidocaine near oxidizing substances like hydrogen peroxide and chlorine. Common home items like hair dye and cleaning supplies may include these chemicals. After using topical lidocaine, methemoglobinemia may develop right away or within a few hours. The first symptoms include fatigue, headaches, and blue skin. Seek immediate medical attention to prevent more severe and potentially fatal side effects, such as seizures, unconsciousness, and irregular heartbeats.
Overdosage
High plasma levels experienced after the therapeutic use of local anesthetics are typically linked to acute emergencies caused by these drugs.
Handling situations involving local anesthetics
The first factor is prevention, which is best achieved by closely monitoring respiratory and cardiovascular vital signs as well as the patient’s level of consciousness following each local anesthetic dose. Oxygen should be given as soon as there is a change.
Maintaining a patent airway, assisted or regulated breathing with oxygen, and a delivery device that allows for quick positive airway pressure by mask are the first steps in the therapy of convulsions. The effectiveness of the circulation should be assessed as soon as these ventilatory procedures are implemented, bearing in mind that intravenous medications used to treat convulsions might occasionally impair circulation. Small intravenous doses of an ultra-short acting barbiturate (like thiopental or thiamylal) or a benzodiazepine (like diazepam) may be given if convulsions continue in spite of sufficient respiratory assistance and if the circulation is stable.
Before using local anesthetics, the clinician should be familiar with these anticonvulsant medications. Intravenous fluids and, if necessary, a vasopressor (e.g., ephedrine) may be administered as part of supportive treatment for circulatory depression.
Both cardiovascular depression and convulsions can cause hypoxia, acidosis, bradycardia, arrhythmias, and cardiac arrest if left untreated. Standard cardiopulmonary resuscitation techniques should be used if cardiac arrest occurs.
When treating an acute lidocaine overdose, dialysis is of very little use.
