Ivermectin seems to have anti-viral properties against Covid-19 in helping to prevent serious illness.
Some governments (Goa in India and Ireland) are recommending this very low cost drug as a prophylactic. I regularly watch the YouTube channel of Dr John Campbell and he is puzzled why this is not being widely recommended. He always gives the source of his data. I recommend you check this out.
Always seek the medical advice of your own doctor!
