All I can find is that when people show symptoms or have been exposed, they are given a home isolation kit with 7 days of medical supplies that include ivermectin. Is that what you mean?

“Three days [ago] Goa issued a Government Order for mass prophylaxis using ivermectin for the people of Goa”, said Dr Suryakant. Goa is the first state in India to use ivermectin in this way, he emphasised. Uttar Pradesh was the first state to issue a Government Order for the use of ivermectin for treatment and prophylaxis for asymptomatic and mild cases of covid-19 and for prophylaxis of health care workers and home contacts.

When I last looked more into Ivermectin and India I found that both https://www.newindianexpress.com/nation/2021/may/12/covid-19-uttarakhand-govt-to-distributeivermectin-tablets-to-allresidents-2301677.html and https://indianexpress.com/article/india/goa-prescribes-ivermectin-for-all-above-18-irrespective-of-symptoms-7310158/ are about decisions to generally give it to all people.
https://www.palmerfoundation.com.au/india-mumbai-move-for-ivermectin-prophylaxis-while-uttar-pradesh-smashes-covid-19-but-drugs-use-suppressed-in-media/ unfortuantely doesn’t say exactly how often it was used in Uttar Pradesh but suggest it’s use for prophylaxis at the end of May was enough to have a big effect. In my own reasoning them predicting three months ago that their strategy involving invermectin does the job matters.
