Antibiotics and a mouth rinse. No home remedies will work. Strep can travel

Per leading experts such as at Johns Hopkins, sulfa antibiotics are the ones we must avoid. I personally have taken amoxicillin-containing antibiotics many times over the years without problems, and it's the best treatment for strep throat. Untreated, strep throat can rarely lead to serious complications such as valvular heart disease.

So will it be ok to take amoxicillin even though I have lupus

Penicillin/amoxicillin is the drug of choice, but for those who are allergic, alternatives can be used.

Ok.
