Does Celiac Cause Sensitivites To Rx's?

Has anyone out there found a link with celiac and allergy-type reactions to various medications? e.g., I take hormone replacement meds since losing my thyroid to cancer. I can only tolerate a tiny dose because my body reacts like I'm allergic to the medication. I've checked and double checked - there is no gluten in any of the fillers/binders. I also find I cannot tolerate antibiotics and a variety of other medications, e.g., severe allergic reactions to Vicodin.

Would love to hear from you if you've had similar experiences. Thanks!
