It may not even be your meds. Have you switched laundry detergent, new soap, new clothes, new linens? How about a new lotion, different furniture, anything like that? I know one time i broke out in a rash from trying on new clothes because of something it was treated with. Also, any new meds? Anything with morphine in it makes me itch. Some antibiotics as well. Could even be something as simple as dry skin since the seasons are changing.
