What medications interact with antihistamine nasal sprays?

Donna Hill Howes, RN
Family Practitioner

If you are taking thalidomide, orphenadrine, or an anticholinergic drug, olopatadine can lead to side effects and should be avoided.

If you are taking eluxadoline, paraldehyde, a central nervous system depressant, or potassium chloride in solid form, azelastine and olopatadine can lead to side effects and should be avoided.

If you are taking rufinamide, topiramate, or an opioid, olopatadine may not be a good option for you.

If you are taking a selective serotonin reuptake inhibitor, azelastine and olopatadine may not be good options for you.

If you use an azelastine nasal spray, you should avoid kava kava.
