Mixed injection with other injectable solutions is not recommended because of the unpredictable effects of the new drug combination. Unless the administration of several different injection drugs is therapeutically indicated, they are usually injected one after another.
Neural therapy is a treatment that uses injections of a local anaesthetic, such as procaine, to treat pain, neuritis, neuralgia, rheumatic diseases, paresthesias, and paralysis. The injections are usually given intracutaneously or subcutaneously, but may also be given intravenously in some cases. The maximum daily dose for adults is 10 ml of the local anaesthetic solution.
