I've been on Nasocort AQ nasal spray to help with my chemical sensitivities. It has definitely helped me be less sensitive to fragrances and other chemicals that produce an allergic/asthmatic response in my body. However, it's really freakin' expensive. Are there any other nasal sprays or other meds that folks have found helpful?
FWIW, I react particularly badly to chemical fragrances and smoke. I don't have quite as intense a reaction to other kinds of chemicals and smells.
