Summary
Both drugs can cause sedation, and combining them may add to drowsiness and impair psychomotor performance. Daytime impairment and reduced alertness may follow. The effect of the nasal spray is smaller than that of oral sedatives, but additive CNS depression remains possible.
What this interaction means in plain words
Amobarbital and Olopatadine intranasal can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Why it happens
Additive pharmacodynamic CNS depression from a barbiturate and a sedating antihistamine.
What to do
Warn the patient about drowsiness and to avoid driving or operating machinery until the response is known. Consider a non-sedating nasal alternative if sedation becomes troublesome.
