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 (tic douloureux), 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.

The dosage of Dehydrated Alcohol Injection for therapeutic nerve or ganglion block varies from as little as 0.05 to 0.5 mL in trigeminal neuralgia to 0.5 to 1.0 mL per interspace for subarachnoid injections. Doses larger than 1.5 mL are seldom required. All injections should be made slowly and only after all steps have been taken to insure precise placement of the alcohol. A 1.0 mL tuberculin syringe is desirable to facilitate accurate measurement of the dose. Separate needles should be used for injection of successive interspaces or other sites. Since Dehydrated Alcohol injection is hypobaric as compared to spinal fluid, proper positioning of the patient is essential to control localization of injections into the subarachnoid space.

When lesser concentrations of alcohol are used, larger volumes are usually injected. A dose of 2 mL of 45% alcohol has been used for injecting individual motor nerves, or from 1.5 to 4.0 mL for epidural injection in children with spastic cerebral palsy; 50 ml of 50% alcohol has been used for celiac plexus blockade.

The LD₅₀ oral dose in rats is 13.7 g/kg. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit, (see PRECAUTIONS).
