Dibucaine
Dibucaine
Dibucaine (pronounced dih-BYOO-kane) is a local anesthetic of the amide type. It is used topically in medicine to numb the skin or other surfaces and is a key ingredient in some over-the-counter hemorrhoid treatments and some throat lozenges.
Etymology
The term "Dibucaine" is derived from its chemical structure, which includes two benzene rings (di-) and a quinoline group (-bucaine).
Usage
Dibucaine is used to relieve pain and itching caused by conditions such as sunburn or other minor burns, insect bites or stings, poison ivy, poison oak, poison sumac, and minor cuts and scratches. Dibucaine works by blocking nerve signals in your body.
Related Terms
- Local anesthetic: A medication that causes reversible absence of pain sensation, although other senses are often unaffected.
- Amide: A group of organic compounds derived from acids by replacing -OH by -NH2.
- Hemorrhoid: Swollen veins in the lowest part of your rectum and anus. When the walls of these vessels are stretched, they become irritated.
- Throat lozenge: A small, typically medicated tablet intended to be dissolved slowly in the mouth to soothe the throat.
Side Effects
Like all medicines, Dibucaine can cause side effects, although not everybody gets them. Some common side effects include redness, swelling, or irritation where the medicine was applied.
Precautions
Before using Dibucaine, tell your doctor or pharmacist if you are allergic to it; or to other amide type anesthetics (such as lidocaine, prilocaine); or if you have any other allergies.
