Summary
Antihistamines given in large systemic doses have been described as making tissues partly resistant to hyaluronidase spreading action. Intranasal or ophthalmic azelastine yields low systemic exposure, so the effect is unlikely to matter clinically.
What this interaction means in plain words
Azelastine and Hyaluronidase have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Azelastine belongs to Respiratory; Hyaluronidase belongs to Miscellaneous.
Why it happens
Proposed antihistamine-mediated tissue resistance to hyaluronidase dispersion; not well characterized.
What to do
If dispersion is inadequate, a larger hyaluronidase dose may be needed. No routine change is required.
What to ask your pharmacist
- Is there anything I should notice while taking both?
- Do I need to tell my doctor at the next visit?
