Do allergy and sinus medications interact with other drugs?

Yes, allergy and sinus medications do interact with other drugs. Antihistamines, which block the body's signals that trigger allergy symptoms, can interact with sedatives, tranquilizers or prescription medications for high blood pressure or depression.

Some antihistamines can increase the effect of sedatives or tranquilizers, increasing the chances you will be drowsy, sleepy or have trouble concentrating, and that can be dangerous if you have to drive or be alert at work.

Some antihistamines may raise or lower your blood pressure as well, which can be dangerous if you already have high or low blood pressure, even if you are taking high blood pressure drugs.

Check with your pharmacist to make sure that the allergy and sinus medications you are taking do not have negative interactions with anything else you are taking, including prescription medications, over-the-counter medicines, supplements or even foods.
