SAFETY ALERT:

The preliminary analysis of Suspected Unexpected Serious Adverse Reaction (SUSARs) from the PvPI database re-veals that the following drugs are associated with the risks as given in the table below:

Health care professionals, Patients/Consumers are advised to closely monitor the possibility of the above adverse events associated with the use of above drugs. If such events are encountered please report to the NCC-PvPI either by filling of Suspected Adverse Drug Reactions Reporting Form/ Medicines Side Effect Reporting Form for Consumer (http://www.ipc.gov.in) or by PvPI Helpline No.1800-180-3024. *Anyone may also kindly report to the Drug Information Centre, RIPANS by [email protected] or sms-8730955168

As we are on the new financial year 2017 of the govern-ment, the Drug Information Centre, RIPANS is also moving forward in providing different information on drug use to healthcare workers of different fields and to the general public. Many queries have been received and answered by the Drug Information Centre and we thank each and everyone for appre-ciating this drug information bulletin. The Drug Information C entre bulletin is planned to be published every month from May 2017, I hope it will continue to benefit all the readers. On April 21st , 2017, the Medical Council of India issued an order to all the registered medical doctors under MCI notic-ing to prescribe drugs to the patients by generic names and not by the trade names, the notice stated that any practitioner who are found not writing prescription in generic names are liable to be punished. This bulletin includes a brief article on generic and branded drugs , stating the differences between the two, it ex-plains briefly on how a generic drug is similar/bioequivalent to the branded drugs. The issue also contains basic antidotes for different kinds of intoxication due to poison or drug overdose. Safety alert on few drugs published by the Pharmacovigilance Programme of India (PvPI) under the Central Drugs Standard Control Organisation is also highlighted.
