Please be careful with Hydroxychloroquine. It has a 30 day or more half life (the range of days is based on how well you metabolize the drug) which means if you take one pill today it takes 30+ days for half of it to be out of your system. To get it down to where it is considered completely out of your system it normally takes 5 half lives - 150+ days. My first Rheumatologist wanted me on Hydroxychloroquine and I declined because of the half life facts and the known side effects. Prednisone has a 3-4 hour half life for comparison.

You can read up on any drug at Drugs.com - it has a lot of god information for patients on drugs.
