Dehydrated Alcohol
Dehydrated alcohol is a highly concentrated ethanol solution used in medical settings as a sclerosing agent to treat varicose veins, hemorrhoids, and certain cystic lesions, as well as a neurolytic agent for managing chronic pain conditions. It works by causing controlled cellular damage that leads to tissue fibrosis and obliteration of targeted structures. This medication requires skilled administration and is typically reserved for specific interventional procedures rather than general prescribing.

Primarily used for treating varicose veins and telangiectasias, hemorrhoidal disease, and certain cystic or vascular lesions. Also employed as a neurolytic agent for nerve blocks in chronic pain management, including trigeminal neuralgia and peripheral nerve pain.
Acts as a protein denaturing agent that causes cellular dehydration and protein coagulation upon direct contact with tissues. This controlled tissue damage leads to fibrosis and eventual obliteration of the target structure, whether a blood vessel, nerve, or cystic cavity.
Must be administered only by trained healthcare professionals with precise anatomical knowledge due to risk of significant tissue necrosis if misplaced. Not for intravenous use. Contraindicated in patients with known ethanol hypersensitivity, peripheral vascular disease, or acute infection at the injection site. Requires careful dosing and monitoring for adverse effects.
