[Side effects of drugs on the equilibrium].

Side effects of drugs on the vestibular system may occur when a drug is injected too fast during chronic application of drugs after discontinuation of drugs Dizziness due to ototoxic drugs is rare because of the symmetric influence on the vestibular system. The oculomotor system most often is found being reversible or irreversible damaged by chronic drug effects especially from barbiturates, psychopharmacologic drugs, anticonvulsives and some antiarrhythmics, whereas the vestibular organs and their pathways usually remain unaffected except from ototoxic drugs. An isolated oculomotor disfunction therefore could be an indication for a drug side effect.
