I started taking Singulair 2 years ago because I had trouble breathing when I lay flat down to sleep at night. My doctor thinks it may be asthmatic allergy symptoms, but he can't explain why it's only when I lay down. Anyways, I had never had a nosebleed in my life until I started taking it, and now I get them almost every other day. Sometimes as soon as I wake up and roll over in the morning blood will pour out of my nose. Many a pillow case has been ruined because of this. I never had nasal allergy problems, but since Singulair clears the nasal passages too, it is making my nose way too dry and causing bad nosebleeds.
