Lidocaine HCl Solution (2% Xylocaine® Viscous)
About: Lidocaine HCl Solution (2% Xylocaine® Viscous)
Lidocaine Hcl Solution, also called viscous lidocaine, is a medication used to numb the mucous membranes of your mouth, gums, and/or throat. Your provider may prescribe viscous lidocaine solution for you if you have mucositis from cancer treatment. Mucositis causes sores or inflammation in your mouth, on your gums, or down your throat. Viscous lidocaine works by blocking nerve cells in the affected area. This causes numbness and can ease pain due to mucositis.
How to Take Lidocaine HCl Solution (Viscous Lidocaine)
Viscous lidocaine can be given on as needed or scheduled basis and should be taken as prescribed by your provider. It is important to make sure you are taking the correct amount of medication every time. Before every dose, check that what you are taking matches what you have been prescribed. Never take more than is prescribed.
Use a measuring cup to make sure you have the right amount of viscous lidocaine. This should come with the medication. Do not dilute (mix) with water or any other liquid.
- If you have sores or irritation in your mouth or on your gums, swish the viscous lidocaine all around your mouth. Once your whole mouth is coated, spit out the viscous lidocaine.
- If you have sores or irritation in your throat, you can gargle the viscous lidocaine in the back of your throat and swallow. If you have pain in both your mouth and down your throat, swish the viscous lidocaine in your mouth, then gargle and swallow. Do not take two doses at one time.
- If you have only a few sores in your mouth, you can use a cotton swab to dip into the viscous lidocaine and put the cotton swab right on the sore.
Avoid eating or drinking for at least 1 hour after taking viscous lidocaine. Since your mouth may be numb, you may have trouble swallowing and could bite your tongue or cheek.
Be sure to tell your healthcare provider about all medications and supplements you take. If you are allergic to any numbing medication, tell your provider before taking lidocaine viscous. Tell your provider if you have liver disease or problems with your heart.
Viscous lidocaine should never be used for children who are teething. Serious side effects and death have happened in children under the age of 3.
Storage and Handling
Viscous lidocaine should be stored in the original, labeled container at room temperature. Keep containers out of reach of children and pets.
If you are no longer taking viscous lidocaine but have some medication left, be sure to throw the left over medication away somewhere so that children or pets cannot get to it.
