Doxy 100 mg Tablet for COVID: Is It Effective?

One of the recent topics of discussion has been the use of doxy 100 mg tablet for COVID. During the early stages of the pandemic, doxycycline was explored as part of combination therapy (often with ivermectin or azithromycin) to manage symptoms of mild COVID-19 cases.

While doxy 100 mg tablet has anti-inflammatory and antiviral properties, it is important to note that its role in COVID-19 is not curative.
