Summary
Antihistamines given at high systemic doses have been reported to make tissues partly resistant to the spreading action of hyaluronidase. The dispersing effect may be reduced, so more enzyme may be needed to achieve the intended result.
What this interaction means in plain words
Cetirizine 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.
Cetirizine belongs to Respiratory; Hyaluronidase belongs to Miscellaneous.
Why it happens
Antihistamines may partially counteract hyaluronidase-mediated tissue permeability; the mechanism is not well established.
What to do
Watch for a reduced spreading effect of hyaluronidase in patients taking antihistamines and titrate the hyaluronidase dose to clinical response.
What to ask your pharmacist
- Is there anything I should notice while taking both?
