Yes I too get odd reactions or side-effects to medications. My Allergist says it is mostly due to my intolerance for some preservatives that are commonly used in prescription medications. It also has to do with some other oddities about my metabolism and how my body processes things. I'm a slow oxidizer, which means it takes my body a lot longer to process chemicals than the average person. This makes for some strange drug reactions.
Just a thought, have you had your thyroid checked recently? Sometimes, low thyroid can cause or increase the likelihood of reactions to meds and also the development of allergies.
