Applying a Topical Anesthetic


Your health professional has prescribed a topical anesthetic medicine for your child to decrease pain associated with a procedure such as an injection or accessing an implanted port. There are several topical anesthetics available; the time it takes the medication to actually “work” and numb the site varies, so it is important to follow the health professional’s directions carefully. Some general guidelines are presented for two common topical anesthetics, EMLA and LMX4. EMLA stands for eutectic mixture of local anesthetics. A topical anesthetic is a medicine that is placed on normal, healthy skin to make it numb. EMLA contains two anesthetics, lidocaine and prilocaine. Be sure to tell your health professional if your child has an allergy to either of these medicines before using EMLA. Use only the amount of EMLA that has been prescribed.


EMLA comes in a cream; the anesthetic disk is no longer available. The cream must be covered with the dressing that comes with the 5-gram tube. There is also a 30 gram tube that is useful if you need to apply the cream several times. A transparent dressing, which is a clear plastic film with adhesive (sticky) edges, is placed over the cream. If you do not have this dressing, you can cover the cream with ordinary plastic film, such as Saran Wrap, and seal the edges of the plastic to the skin with tape. You cannot use ordinary Band-Aids because the cream will leak out.


LMX4 is a 4% liposomal lidocaine preparation that is applied just like EMLA; the main difference is that LMX4 is reported to numb the skin within 30 minutes. The site should not have any alcohol-based product on it before this anesthetic is applied. This topical anesthetic is available without a prescription; however, you should consult your health professional regarding the size of the tube to be purchased.


In Canada a 4% amethocaine topical gel (Ametop) may be used. This topical anesthetic is applied in the same manner as EMLA but takes only 30 minutes to be effective. Consult your health professional for use of Ametop gel.


The general directions that follow address EMLA; however, keep in mind that except for the time of application, all three are essentially applied in the same manner.
