New Delhi: Union Health Minister Dr. Harsh Vardhan on Sunday cautioned against “routine use” of plasma therapy and anti-viral drug Remdesivir to treat COVID-19 patients, stating that these are “investigational therapies” and should be adopted “rationally”.

Anti-viral drug Remdesivir and Convalescent Plasma Therapy (CPT) are being used widely, besides other drugs, to treat critically ill COVID patients in many States, including Maharashtra and Delhi. The pandemic has infected more than 60 lakh people in the country. Their use is said to have increased especially after CPT was administered to two Delhi Government Ministers.

“Regarding the wide usage of investigational therapies such as Remdesivir and plasma therapy, the Union Health Minister has stated that the Central Govt. has issued regular advisories regarding their rational usage. Private hospitals have also been advised against routine use of these investigational therapies. Doctors in the States and Union Territories are being made aware of this through webinars and during tele-consultation session of AIIMS-New Delhi,” Health Ministry statement read.

Two Ministers in the Delhi Government who tested positive for coronavirus — Health Minister Satyender Jain and Deputy Chief Minister Manish Sisodia — have been given plasma therapy at a private hospital in Delhi when their condition deteriorated.

Jain, who recovered from COVID-19 in June, had vouched for CPT’s efficacy a day after a study by India’s top medical research body  ICMR stated that giving plasma had negligible effect on reducing death risk.
