*As of December 2020, there is currently only a single FDA-approved therapeutic for the treatment
**However, there are many therapeutics that have been considered for therapy and available for off-label use and through FDA Emergency-Use-Authorization.

New insights on the antiviral effects of chloroquine against coronavirus: what to expect for COVID-19?. Int J Antimicrob Agents. 2020 Mar 12:105938. doi: 10.1016/j.ijantimicag.2020.105938.</ref>
 
====[[Azithromycin]]====
*Macrolide antibiotic with purported anti-inflammatory effects in certain respiratory conditions such as [[COPD]].
*A small French study with 20 patients showed benefit in reducing symptoms and viral carriage when combined with [[Hydroxychloroquine]]. <ref>Gautret P, Lagier JC, Parola P, et al.

===[[Anticoagulation]]===
*Anticoagulation may be associated with lower mortality due to COVID-19 associated vascular thromboemboli resulting in increased dead space ventilation. <ref>Tang et al. J Thromb Haemost 2020 Mar 27. PMID: 32220112 </ref>
*Do not give anticoagulation to patients who have a high risk of bleeding as judged by the treating physician.
*Before starting anticoagulation, check cbc, pt/ptt, d-dimer. Hold anticoagulation if platelet count <50,000 or INR >1.5.
*In admitted patients with moderate or severe COVID-19:
*High risk: No definitive criteria, but clinician should use a combination of respiratory distress, o2 requirement, elevated d-dimer, creatinine, and crp in making determination.
 
====Dosing====
*ICU: Heparin drip per PE protocol (goal PTT 70 - 110) or Enoxaparin SC 1mg/kg BID.
*High risk admitted patients:
**CrCl > 50: [[Enoxaparin]] SC 1m/kg BID
**CrCl <50:
***On renal replacement Therapy: [[Apixaban]] 5mg PO BID or heparin drip PE protocol.
***Not on renal replacement Therapy: [[Apixaban]] 5mg PO BID or Adjusted Dose Enoxaparin.
*Not high risk:
**[[Apixaban]] 2.5-5.0mg PO BID or Enoxaparin SC 40mg QD.
