Ibuprofen rarely interacts with non-sedating antihistamines such as loratadine or cetirizine. No significant drug-drug interactions appear in standard references.
Ibuprofen does interact with sedating antihistamines like diphenhydramine (Benadryl). The combination may increase drowsiness, dizziness, and stomach upset.

What happens if you mix ibuprofen and diphenhydramine?

When taken separately, users report occasional stomach pain or next-day grogginess.
