Alcohol is a flammable liquid and should be kept cool and away from any heat source. Alcohol injections should be made with care to avoid unwanted tissue necrosis. Proper positioning of the patient is essential to control localization of injections of dehydrated alcohol (which is hypobaric) into the subarachnoid space.
There is currently no manufacturer warning information available for this drug.
Dehydrated Alcohol Injection is indicated for therapeutic neurolysis of nerves or ganglia for the relief of intractable chronic pain in such conditions as inoperable cancer and trigeminal neuralgia (ticdouloureux), in patients for whom neurosurgical procedures are contraindicated. Relief of trigeminal neuralgia usually is only temporary. Other conditions for which injection of alcohol has been reported include glossopharyngeal neuralgia, angina pectoris and severe claudication due to peripheral vascular insufficiency.
Alcohol concentrations of 40 to 50% (prepared by appropriate dilution of dehydrated alcohol) have been used for epidural or individual motor nerve injections to control certain manifestations of cerebral palsy and spastic paraplegia. Similar concentrations also have been injected for celiac plexus block to relieve pain of inoperable upper abdominal cancer, and have been injected intra-and subcutaneously for relief of intractable pruritus ani.
Dehydrated Alcohol Injection, USP consists of not less than 98% by volume of ethanol (ethyl alcohol). Dehydrated alcohol is hypobaric in relation to the cerebrospinal fluid. It is injected proximate to nerve tissues and into spinal subarachnoid spaces to produce degeneration of nerve function (neurolysis) for control of chronic pain.
The product contains no bacteriostat or antimicrobial agent (other than ethanol) and no added buffer.
Dehydrated alcohol is a clear, colorless liquid miscible with water and has the following structural formula:
