Hi, i'm on plasmaquine and methotrexate 7.5mg x 1 per week for arthritis. i'm concerned that the methotrexate may weaken my immune system and make me more vulnerable to covid-19. would it not be safer to discontinue use untill the threat has passed?

Legitimate concerns, your rheumatologist or current prescriber for above meds would be best to comment on options in the clinical context of your condition. Your known condition that has been treated with above meds is a threat, too.

Vaccinations including flu, COVID-19 and pneumococcal should be kept up to date. Avoid crowds, use a mask and good hand washing. Discuss the medications with your specialist. Watch for signs of fever,cough and shortness of breath.
