" Ivermectin is currently not approved in the UK for the prophylaxis or treatment of COVID-19," [1]
There are no good studies demonstrating the validity of Ivermectin, and the Oxford study is not complete and there's no indication results are positive.

It doesn't look like it works, though there is some possibility it will, but we'll only know when the Oxford trial is complete. Given the knowledge we have today, it just isn't a therapy for COVID.
