Nosebleeds from high blood pressure are characterized by a relatively large amount of bleeding, and the bleeding from the nose is usually in the form of a jet, which is not easy to stop. Once this happens, the first step is to fill the nasal cavity with a nearby tablecloth or toilet paper to stop the bleeding. In addition, it is important to go to the hospital to have your blood pressure monitored and treated accordingly by an ophthalmologist or ear, nose and throat specialist. In terms of controlling blood pressure, it is important to take antihypertensive medications at regular intervals, and antihypertensive medications generally include nifedipine, captopril, valsartan, benadryl, etc. All of these medications can be used in combination or individually for the purpose of controlling blood pressure.
