I have concentrated tonic syrup (contains quinine). Multivitamin with zinc.
Eye vitamin recommended my my eye doctor that has extra vitamin D.
I do not have azithromycin, which should only be taken if you have, or suspect you have, the whoo-hoo flu.
I take zinc, tonic water, vitamins C and D, multivitamins, plus walk in the sunshine at least one hour a day.
