Hi

Antihistamines and corticosteroids are generally safe for people with high blood pressure. However, be sure to check with a doctor before taking any medications, even those that are over-the-counter.

Antihistamines help to prevent allergy symptoms by blocking the chemical release of histamine. They come in the form of eyedrops, nasal sprays and pills. Examples of eyedrops include Alaway, Visine-A and Zaditor, and can be purchased from a drug store. Prescription eyedrops include Patanol, Albalon and Emadine. Prescription nasal sprays include Astepro, Astelin, and Patanase.

Thanks
