Tramadol-induced parkinsonism: a case report of a 75-year-old woman.

Adverse drug reaction (ADR) is a form of unwanted reaction and is the crucial reason for illness and death. Tramadol-induced parkinsonism is a kind of ADR that occurs after the repeated intake of tramadol. Long-term exposure to tramadol has been known to induce tremor and alter the functioning of dopamine. This case report introduces a 75-year-old woman diagnosed with tramadol-induced parkinsonism due to the administration of tramadol for the treatment of post-operated (breast cancer) acute onset of severe pain on the left side of the chest. The assessment of the offending drug was carried out via Naranjo probability scale. A score of 6 was reported for this patient, defining tramadol as a probable cause of this reaction. For the management of the drug-induced parkinsonism, levodopa/carbidopa was prescribed and the symptoms related to parkinsonism resolved within a week. The age of the patient and the female gender is considered to be the main risk factor for the occurrence of such reaction. This case report is an attempt to spread awareness about the negative consequences of long-term use of tramadol in old patients. Thus, the medical practitioners must be very careful while administering tramadol to the old aged population.
