Tamiflu the remedy of choice for treatment of influenza is causing pandemonium worldwide with more and more reports of psychiatric side effects, regulators said today. The U.S. FDA has approved the labeling change after series of cases of self-injury and mental disorientation were reported from Japan by people who had been taking this drug Unfortunately most of these reports concerned children.
The new label approved by U.S FDA cautions medical practitioners to be cautious when prescribing this drug and urges them not to leave any stone unturned if the slightest report of abnormal behavior while monitoring the patients with an eagle's eye.Due to lack of concrete evidence regulatory agencies are still unsure whether these abnormal psychiatric symptoms reported are actually caused by the drug or partly caused by the influenza virus or because of both.
