Some states have a longer statute of limitations. In that case, you should keep your tax records for as long as the statute of limitations is still open for a particular tax return. The statute of limitations gives the IRS three years to audit your tax return.
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.
The Food and Drug administration approved the use of lidocaine as an anesthetic in 1949, states MedicineNet. This drug is used to numb a certain area of the body without affecting the surrounding nerves. The medicine will begin numbing the area within 90 seconds. It hinders nerve impulses from reaching the brain so the patient does not feel pain. Some side effects include pain at the injection site, dizziness, weakness and drowsiness. Lidocaine is safe for pregnant women as there are no known side effects to the fetus.
