"A drug to treat head lice and worms will now be administered to Covid-19 patients and those at high risk of infection in Uttar Pradesh. The anti-parasite drug, ivermectin, has been used in clinical trials in Delhi hospitals but Uttar Pradesh is the first to approve its statewide use in the Covid-19 prevention protocol. .. The idea is that its immunomodulation properties — activating the immune system — could help stave off Covid-19. “Ivermectin has been used for several years to treat many infectious diseases … It has low adverse effects. We have been providing the drug to Covid-19 patients in our isolation ward. Positive results were achieved,” said Dr Sanjay Kala, principal of SN Medical College. And the range of its use has been considered worth exploring. “It has antimicrobial, antiviral and anti-cancer properties. It has shown effective results in Covid-19 studies,” said Dr Prashant Prakash, professor of pulmonary medicine at the college."
