How do you treat a sulfa sensitive patient for cold?
Sulfa drugs are usually used to treat bacterial infections, not viral infections like a cold. So no sulfa drugs are needed for sulfa-sensitive patients with viral infections like the common cold or flu. There is no equivalent to antibiotics that are used to kill bacteria that are for treating viruses. Bacteria can be killed and antibiotics, like sulfa drugs, are what can do that. Viruses are not living organisms, so they can't be killed. They can be made inactive, but that is possible only when your immune system attacks and gets rid of them, there are no drugs to do that. See the related question below for more information about treating a cold.
