    Hi Josh, As per your statement, already you are taking RIFAMPIN-ISONIAZID-ETHAMBUTOL which is used to treat TB caused by bacterial infections, but now you want to take Amoxiclav. So in this condition I would suggest you to consult your physician regarding this, since he only knows about the severity of your body conditions.
