An overdose of benzocaine can cause fatal side effects if too much of the medicine is absorbed through your skin and into your blood. Use the smallest amount needed.
Before taking this medicine
Do not use Dermoplast if you have ever had methemoglobinemia in the past.
Do not use Dermoplast on a child younger than 2 years old.
An overdose of benzocaine can cause fatal side effects if too much of the medicine is absorbed through your skin and into your blood. This can happen if you apply more than the recommended dose.
Fatal overdoses have occurred when numbing medicines were used without the advice of a medical doctor (such as during a cosmetic procedure like laser hair removal). Be aware that many cosmetic procedures are performed without a medical doctor present.
Ask a doctor or pharmacist if this medicine is safe to use if you have:
a personal or family history of methemoglobinemia, or any genetic (inherited) enzyme deficiency;
heart disease; or
if you smoke.
Ask a doctor before using this medicine if you are pregnant or breast-feeding.
If you apply Dermoplast to your chest, avoid areas that may come into contact with the baby's mouth.
How should I use Dermoplast?
Use Dermoplast exactly as directed on the label, or as prescribed by your doctor. Read all medication guides or instruction sheets.
Your body may absorb more benzocaine if you use too much, if you apply it over large skin areas, or if you apply heat, bandages, or plastic wrap to treated skin areas. Skin that is cut or irritated may also absorb more topical medication than healthy skin.
Use the smallest amount of Dermoplast needed to numb the skin or relieve pain. Do not use large amounts of benzocaine topical. Do not cover treated skin areas with a bandage or plastic wrap without medical advice.
Do not use Dermoplast to treat large skin areas or deep puncture wounds. Avoid using the medicine on skin that is raw or blistered, such as a severe burn or abrasion.
To treat minor skin conditions, apply a thin layer of benzocaine topical to the affected area. If using the spray, hold the container 6 to 12 inches away from the skin. Do not spray this medication onto your face. Spray it instead on your hands and then rub it onto the face, avoiding contact with your eyes.
Clean the area with soap and water before applying Dermoplast.
Call your doctor if your symptoms do not improve or if they get worse within the first 7 days of using Dermoplast. Also call your doctor if your symptoms had cleared up but then came back.
Store at room temperature away from moisture and heat. Do not freeze.
What happens if I miss a dose?
Since Dermoplast is used when needed, you may not be on a dosing schedule. Skip any missed dose if it's almost time for your next dose.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. An overdose of benzocaine topical applied to the skin can cause life-threatening side effects such as uneven heartbeats, seizure (convulsions), coma, slowed breathing, or respiratory failure (breathing stops).
What should I avoid while using Dermoplast?
Dermoplast is for use only on the surface of your body. Avoid getting this medication in your eyes.
